Modular pneumatic three-way ball valve principle and characteristics

in the past the coke oven of coking plant of high pressure ammonia water injection system structure of high and low voltage conversion system generally adopts the traditional L pneumatic three-way ball valve, due to the working conditions of the parts of the special, L pneumatic three-way ball valve in the leak installed for months or even a few days, to reduce the system pressure, leakage of high pressure ammonia sucked to pulverized coal in the coke oven gas collector, serious cause chamber negative pressure, both influence of coke quality, rigor and furnace. Due to the modular pneumatic three-way ball valve installed on the top of the coke oven, where the temperature is high, poor working conditions, pneumatic valve replacement to bring very great difficulty. Pneumatic valve frequent replacement, also caused great economic losses to the factory, and also seriously pollute the environment. http://www。 zgbfw。 Com/info /

principle and characteristics of the modular pneumatic three-way ball valve: http://www. zgbfw。 Com/info /
in order to solve the above problems, YQF - The structure of the pneumatic valve type combined tee as shown. It consists of straight through pneumatic valve and floating ball sleeve check pneumatic valve, pneumatic valve on the left side of the ball after high pressure system, on the right side of the check system low pressure pneumatic valve, intermediate exports to discharge pipe, when the pneumatic ball valve closing, high channel cut off, check the pneumatic valve pneumatic valve driven by low voltage medium automatically open, low pressure ammonia by export channel discharge in the middle. When the pneumatic ball valve opens, high pressure ammonia will check into the pneumatic pneumatic valve pneumatic valve seat valve, check valve pneumatic valve closed, low voltage channel is cut off, high pressure ammonia by export channel discharge in the middle. After the injection, close the pneumatic ball valve, check valve pneumatic valve automatically open, low pressure ammonia and automatic discharge. Therefore, as long as like operating traditional pneumatic three-way ball valve, pneumatic ball valve pneumatic valve rod ℃ switch, which can finish high and low pressure switch. Modular three-way pneumatic valve main characteristics are as follows: http://www. zgbfw。 Com/info /
, as the straight through the floating ball in the modular three-way solenoid pneumatic valve opened and closed only on one side of the high pressure system, rather than a tee conversion function, therefore, even if the ball in use after a period of time with the pneumatic valve seat assembly pre-tightening force disappears, the spheroid and pneumatic valve seat, a gap between the pneumatic ball valve is closed, the pressure of high side medium pneumatic valve seat can still push the ball into the export side, close contact between the sphere and the export side pneumatic seat, so the pneumatic valve still has good sealing performance, modular three-way pneumatic valve completely solve the traditional pneumatic l-type three-way ball valve seal failure problem easily. The low voltage side check pneumatic valve adopt stainless steel, unique design, action quick, reliable sealing, long service life. http://www。 zgbfw。 Com/info /
and the structure of modular three-way solenoid length and connection size is the same as the traditional aerodynamic l-type three-way ball valve, pneumatic valve replacement is convenient. http://www。 zgbfw。 Com/info /
and modular three-way solenoid, simple and convenient operation, and the traditional aerodynamic l-type three-way ball valve is exactly the same. http://www。 zgbfw。 Com/info /
, pneumatic valve body to the integral structure design, can effectively prevent the leakage of pneumatic valves, pneumatic valves of the overall design more hasten is perfect. http://www。 zgbfw。 com/info/
