The development of China's valve industry

The implementation of diversified sales strategy, efforts to open up international markets to expand exports.

According to China Valve Association statistics show that currently we valve industry excess capacity, about 40% of production capacity venting, the face of such a huge excess production capacity, the most effective way is to implement diversified sales strategy, vigorously explore the international market . The current international market every year about 60-70 million outlet gas safety valve, China exports 1.5 million, less than 2% share, this side has great potential. First, open up international markets to focus on foreign talent, a group will operate foreign trade professionals understand foreign languages; Second, we must learn to use the Internet and information technology, to make customers to capture business opportunities; and third, and some domestic foreign trade companies can expand cooperation with its channel exports; fourth qualified enterprises can set the point of sale or setting up factories abroad. In recent years, Shandong Yidu valve plant and Suzhou 526 plants are better achieve market diversification. A significant increase in the proportion of exports to ease the contradiction between domestic orders inadequate. Open up the international market but also pay attention to our own advantage, selecting the right export products, currently mainly in the export of labor-intensive products such common valve, in addition to semi-finished casting blank is also very good export prospects.

Fourth, improve enterprise management level, the implementation of management innovation, deepen enterprise reform, the implementation of institutional innovation is in the Gas Control Valve industry in China is currently alternating with a new round of restructuring period.

Has been declining proportion of state-owned enterprises, private, foreign-funded enterprises developed rapidly. According to incomplete data estimation; the proportion of the assets of China's valve industry at this stage, accounting for 40 percent of private, state-owned 30%, the remainder being funded, military enterprises occupy, is expected in the coming years of private and foreign-funded enterprises share will be further expanded. Now Wenzhou private enterprises developed rapidly, and the considerable number of enterprises with certain scale and strength, such as Bethel, never a Zhejiang-dimensional all profits and other enterprises. Current industry mostly state-owned heavy burden due to historical reasons, the mechanism is not live, operational difficulties, but many companies remain equipment, personnel, technology, brand and other advantages; to solve the immediate difficulties to deepen reform, institutional innovation, and fully revitalize the stock of assets, diversify their ownership and the establishment of modern enterprise system. For the rapid development of private enterprises, despite shortcomings and historical baggage mechanisms do not exist, but its development should focus on improving the management level, the implementation of management innovation, to avoid falling into the "family" and "paternalistic" management cliche. In short, the valve industry is full of hope. As long as we have to "Congress" spirit pointer, fully implement the "Three Represents", we will be able to revitalize the valve industry for China's economic development and contribute to the full realization of off target.

China's valve industry in a very favorable development opportunities

Valve industry is an important branch of our general machinery. Its products as critical fluid control equipment is widely used in petroleum, chemical, metallurgy, electric power, urban construction, environmental protection and other industries. Currently, the gas stove safety manufacturing industry is in a very favorable development opportunity. This is because:
First, the state-owned economy continued to develop steadily. Fixed asset investment expanded. Especially several centuries, "natural gas" start "West to East", "South" and the project requires a lot of valve products matching;
Second, with the accession to the WTO, international trade, lowering the threshold and developed countries, the adjustment of product structure, China is becoming the world's largest plant of this emerging trend, manufacture Gas Heater Valve products face greater space for development.
So how to seize the strategic opportunity to accelerate the development of the valve industry. Industry professionals were analyzed from the following aspects:
First, actively promote the consolidation and reorganization among enterprises, as soon as possible to create a group of grade scale enterprise groups.
Valve industry currently produces about 5,000 companies with annual sales of more than 50 million just seven, more than one million three, enterprises with more than 200 million yuan a no. Domestic market share is only the Sufa an enterprise more than 2% the rest were below 1%. This is difficult to produce shocking scale enterprises in the market, and competition with the industry's well-known international companies more difficult. To change this situation as soon as possible, in addition to their own growth factors, the most effective way is through inter-firm alliances, mergers, and restructuring to achieve corporate expansion capital to further expand market share, remain unbeaten in the competition. It is more popular in today's international economic practices, the problem is the development of a directional valve industry in the future period. To emancipate the mind on this issue, according to Congress's "new breakthroughs in reform, the development of new ideas" requirement breaking regional boundaries, breaking the boundaries of ownership, breaking the traditional boundaries of specialization. Whenever possible inter-enterprise union can do to try bold, with 3-5 years and strive to create value of over 500 million and the number of 1 billion yuan of enterprise groups.
Second, pay attention to the adjustment of product structure, the courage to technological innovation, research and development of high value-added products and the international advanced level.
China's Oven Safety Gas Valves industry is now able to produce more than a dozen categories of products.  Such as gate valves, globe valves, ball valves, butterfly valves, safety valves, check valves, throttle valves, plug valves, pressure reducing valves, diaphragm valves, steam traps, emergency shut-off valve, the maximum temperature 570 ℃, the lowest -196 ℃, maximum pressure 600MPa, the maximum diameter 5350MM. Despite the strong support of these products in the domestic economic construction, but it should be clear that most of our products belong to general technical content or labor-intensive products, few have the international advanced level. Recently West-East main line bidding, we all lost the valve business is a regrettable fact. Bitter experience. Valve industry to revitalize national industry to develop there must be implementation of technological innovation, the adjustment of product structure, have the courage to research and development of high-tech, high value-added work with the international advanced level of control valves and valve products such as automatic valves regulating valve, three through the confluence wide, three-way diverter valve, safety valve; ball valve type metal seal all-welded, high-parameters of large diameter valve; and a power plant supercritical C12-A steel valves. Technical implementation of innovative research and development of new products have a couple of choices, one through and research institutions and institutions, such as the recent Kaifeng High Pressure Valve Factory and the Chinese Academy of Sciences under the "three-dimensional" companies to develop power plant boiler main steam valve is a leading international level product, its "pressure drop" significantly below international standards, in the power plant industry has a very prospect; the second is in the form of foreign cooperation or technology transfer, the Zigong High Pressure Valve Co., Ltd. Xin Bilun cooperation with the Italian company is shortened our ball product gap with foreign countries. In addition to these practices, qualified enterprises can be developed independently.

Development Trend of China's pressure regulating valve analysis

In recent years, with the changing environment of industrial technology, advanced manufacturing technology are eager to enter the Gas Heater Valve manufacturing. Most manufacturers are in the application of advanced manufacturing technology, investment and manufacturing execution systems used to achieve process automation and CNC machine tools, die-casting, the whole mold and other high precision molding technology, high-precision grinding machines, high efficiency and precision processing technology, surface modification and coating of special processing and material modification technology to produce sophisticated, usable, reliable, high-quality products --- flow control valve from tiny to large diameter valve; from the traditional to the eccentric single seat valve type rotary valve, V-type ball valve, axial flow valve; from the anti-surge, anti-cavitation cavitation, abrasion resistant to high temperature and pressure regulating valve special valve, special valve; from the big thrust of the pneumatic actuator to quickly respond to the electric actuator; from safety assurance process tightly closed to ensure the environment ultralow leakage. Regulating valve and the development of petroleum and petrochemical process control simultaneously, the formation of the whole process, large-scale, high-parameter products, basically meet the control requirements for petroleum and petrochemical production.
A pressure regulating valve, also known as self-balancing valve, flow control valves, flow control, dynamic balancing valves, flow balancing Gas Valves, is an intuitive and easy flow regulation control device, the pipe network application traffic control valve can be set directly from the design constant flow, the valve can be in the action of water flow automatically eliminate the remaining pipeline pressure head and pressure fluctuations caused by deviation, no matter how the pressure changes in the system are kept constant flow setting, the valve These features enable a complete network flow regulator to tune into a simple flow net work distribution, effective solution pipe network hydraulic imbalance.
Pressure regulating valve without external energy, energy in the absence of electric airless workplace, convenient and saves energy.
Finely segmented pressure range and cross each other, high regulation accuracy.
Pressure setting value can be set continuously during operation.
After the pressure regulator Oven Gas Valve

 on the front than the back pressure valve and the valve pressure is available from 10: 1 to 10: 8.
Rubber diaphragm type detection, high precision actuators measured, sensitive.
Using pressure balance mechanism, the regulator valve responsive and precise control.

Pressure relief valve in the car use

     When a modified car speeding off from the side, we often hear the "hum ......" After a period of accelerated engine sound, came the "ci ......" bang - it gives people a

momentum transfer full of feeling. This is where the sound is coming from? Why on ordinary civilian car, or some high-performance sports cars do not have such a voice (and some ordinary modified car there)?
     In fact, this unique "ci ......" sound is the sound pressure relief valve turbocharged engine emitted when the Safety Valve can be said that all of the turbocharged engine will produce this sound, but for everyday civilian vehicles , the manufacturers would this sound as noise to deal with in the design, to reduce it as much as possible. Approach is to vent the pressure within the intake manifold, so very little noise - this stove valves method is called internally drained.
When we depress the accelerator pedal acceleration, throttle opening, engine exhaust temperature and high pressure exhaust energy driven rotation of the turbine exhaust gas, when the speed reaches the turbocharger work (ie the turbine rotating at 100,000 rpm per minute) turbochargers before compressing the air around the engine intake air increases, improve engine power.
     At this point, we need in the intake duct installation of a pressure thermostatic valve device to remove the pipe from the intake of excess high-pressure turbo compressed air. In fact the pressure safety gas valve is a valve installed on the intake pipe for controlling the supercharging pressure. Opening and closing of the Gas Top Burner Valve is controlled by the ECU (electronic control unit) operated solenoid. ECU will be based on high and low pressure turbine outlet supercharged to make judgments, once the pressure exceeds a Gas Control Valve, will be on the electromagnetic coil is energized or de-energized control to open or close the Oven Safety Gas Valves.
     When the pressure pilot valves is closed to ensure that there is sufficient intake pipe inlet pressure as the basis, when the Manual Gas Valves is open can vent excess gas into the atmosphere, reducing the pressure inside the inlet to protect the engine air intake pipe. So we hear the modified car "ci, ci" sound is relief at the sound of the exhaust pressure Range Dual Safety Valves.
