Card sets of gas heater valve installed

(1) according to the requirements of Chapter 9 of the need for pickling pipes should be pickled;
(2) according to the required length by sawing or patio heater gas valve  machines and other equipment off the tube, and definitely not broken with solvent (such as flame cutting) or cutting wheel; remove the tube ends inside and outside round burrs, metal chips and dirt; removing rust-proof pipe fittings agents and dirt; but also to ensure the pipe roundness;
(3) the nut, ferrule has set into the tube, card sets Gas Control Valve the front edge (diameter end) from the mouth of the tube at least 3mm, then taper pipe into the connector body, until the top;
(4) Slowly tighten the nut, turn the gas safety burner valve until it does not move, then tighten the nut 2 / 3-4 / 3 laps;
(5) Remove the check card sets whether to cut the pipe, the location is correct. Card sets are not allowed to move axially to slightly rotate;
(6) Tighten the nuts again after passing inspection.

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.
