Gas heater control valve classified by connection
(1) screw type (tube) installation and connection. Gas Heater Control Valve ports connecting screw fittings and pipes and other components, and thus fixed in the pipeline. This approach applies to simple hydraulic system.
(2) screw-mounted connection. Each port gas control valve are arranged in the same mounting surface, and there is a corresponding fixed oil port connecting plate with screws and Heater Gas Valve, and then pipe fittings and pipe connections with other elements; or put a few in a gas control valve with screws manifold
On different sides of the punch in the manifold, each valve is composed of communication loop. When removing the gas control valve due to other components without removing connected, so this installation connection broader application.
(3) Modular installation and connection. Below the gas control valve connection joint surface, the oil ports respectively in these two surfaces, and the same size gas control valve ports connected to the same size. Each gas control valve in addition to its own function, but also play a role in the oil passage, the gas control valve will be stacked into each other loops, no pipe connections, so the structure is compact, small pressure loss.
(4) Flange mounting connection. And screw connection similar, but instead of flanged screw fittings. For Path! 32_ or larger flow systems. Its high strength, reliable connection.
(5) cartridge installation and connection. No separate body such Propane Control Valve, unit body from spool and sleeve and other components of the cartridge in the pre-hole block, connecting screws or the cover plate, and within a block passage through the various gas control valve connected to form a circuit block plug body and play a role in the pipeline. This is a new way to adapt to the installation and connection of the hydraulic system integration and developed.

Category of gas heater control valve
Hydraulic Gas Heater Control Valve is a hydraulic system to control fluid direction, pressure and flow components. With these valves, actuators will be able to start to stop, direction, speed, action sequences and the ability to overcome the load control and regulation, so that all types of hydraulic machinery can be required to work in a coordinated manner.
Classification of hydraulic valves
A zoning [Press]
Hydraulic valves can be divided into the directional gas heater control valve (check valve and switching valve), the pressure gas heater control valve (such as relief valves, pressure reducing valves and sequential valves, etc.) and a flow Gas Grill Control Valve (such as throttle and governor valves, etc. ). These three types of valves can be combined with each other according to need to be a combination of valve, such as a one-way valve Chuan page order, one-way throttle valve, electromagnetic relief valve, etc., making it compact and simple connection, and improve efficiency.
[B] by the working principle
Hydraulic valves can be divided off valve (or on-off valve), servo valves, proportional valves and logic valves. Off valve after it is set only in the state it is set to work, this chapter will focus on the most widely used valves. Servo and proportional valves can be continuously or proportional control system according to the input data signal. Action elements press pre-programmed logic logic Propane Control Valve control the execution of the program.

The problems of gas heater valve in working process
gas heater control valve does not operate a) the system does not run A, flow-type softening valve, run the flow is set to 0. B, automatic filter Gas
Grill Control Valve in the F-00 to F-01 or greater. "Run" position C, the positioning plate of the Hall element is damaged. The main cause of valve leakage. D, F78 distribution valve gas heater control valve inlet or drain plug. Automatic gas heater control valve does not operate A, main board failure. B, motor, motor control board is connected with the motor pinion or transmission damage, leading to the terminal large gear on the motor can not drive the spool rotation. C, with a hand on the handwheel Gas
Control Valve, such as F63, F67, F68, intermediate gear and motor gear or gear wheel slip terminal. D, water quality is poor, resulting in a large resistance between the sealing sheet, the motor does not move with. E, the valve is stuck between objects or large gear motor gear and terminal objects resting motor with fixed. F, a foreign body water, damaged or stuck valve. G, the water pressure is high, the motor does not move with.

Gas heater control valve does not work
1. softener or Gas Control Valve no longer a student), the controller can not control the rotation of the motor A, the gas heater control valve power interruption: damage to equipment failure or power adapter (no display screen). If no power but no display screen, can be used the same type of power supply for testing; now Run the new Propane Control Valve mainly uses two types of power adapters, output voltage and current are DC12V, 1500mA and DC24V, 1500mA. B, motor and motherboard cable shorted. Water immersion or valve leakage control panel, this phenomenon can occur when such installation. C, the motherboard is damaged and can not control the rotation of the motor. D, motor damage. Mainly caused by patio heater control valve leakage. 2), the regeneration time setting unreasonable time or flow regeneration program shows yet to come, but the actual water hardness has been exceeded. A, time type, the regeneration time is set incorrectly, exceed the maximum of water softener system cycle. If this should be renewable once for two days, is set to 20 days renewable once. B, flow type, the total flow is not cut down or decreasing slower than the actual speed, the meter is damaged, no instantaneous flow. For two main reasons: ① suck iron impeller is stuck or foreign body material, can not be rotated. ② meter meter cord is damaged or loose with the motherboard socket. ③ control board failure. 3), the motor can not control spool rotation.

The use of gas heater control valve
Pressure range of different operating pressure range of gas heater valve is lower than the hydraulic valves. Working pressure gas heater valve is usually less than 10bar, few can reach within 40bar. However, working pressure of the hydraulic valves are very high (usually less than 50Mpa). If the gas heater valve in excess of the maximum allowable pressure. Often a serious accident. Use different characteristics than the general gas heater valves hydraulic valves compact, light weight, easy to integrate installation, high Gas
Heater Control Valve operating frequency, long service life. gas heater valve forward low power, miniaturization direction, low-power solenoid valve has appeared only 0.5W of power. Can be directly connected with the computer and PLC programmable controller can also be mounted on a printed circuit board with electronic devices, connected via a standard gas-electric circuit board, save a lot of wiring for pneumatic industrial robots, complex manufacturing assembly line and other occasions.

Performance comparison gas heater control valves and hydraulic valves
Energy may be different pneumatic components and devices Pneumatic gas station method (a) use, depending on requirements and control points to adjust their working pressure Gas Heater Valve. Hydraulic valves are equipped with the return line to facilitate the collection of used hydraulic oil tank. gas heater control valve can be directly compressed air to the atmosphere through the exhaust port. (B) leakage of hydraulic Gas Control Valve for the different requirements of outward leakage demanding, but a small amount of leakage of internal components is allowed. gas heater control valve, the valve seal in addition to the gap, in principle, allow the internal leakage. Internal pneumatic valve leak there is a risk of accidents. For pneumatic tube, it allows a little leakage; leaking hydraulic pipes will cause the system pressure drop and pollution of the environment. (C) for lubrication requirements of different hydraulic system working medium for hydraulic oil, Gas Heater Control Valve there is no requirement for lubrication; pneumatic system working medium is air, the air without lubrication, so many pneumatic valves require mist lubrication. Gas heater control valve parts should be the choice of materials less susceptible to water corrosion, rust, or to take the necessary measures.
