Question Pressure regulator valve closing pressure is too low 2022-08-31 09:18:46.866

The closing pressure of the pressure regulating valve is low, that is, the unloading time of the air compressor is too long. Check whether the check valve at the air outlet is damaged or whether there is any foreign matter between it and the valve seat, whether the conical spring support washer of the check valve jumps out, and check whether the ventilation hole on the upper cover of the pressure regulating valve is partially blocked by dirt. The above reasons will cause the failure of low working pressure.

Question Does the pressure regulating valve have an unloading function? 2022-08-31 09:18:30.537

As the system air pressure continues to rise, the pressure regulating valve has no pressure regulating and unloading function. This is mainly due to the failure of the pressure regulating valve. Check the gas equipment and whether the adjustment bolts are too tight, and whether the exhaust holes on the valve body are blocked by foreign objects or oil.

Question Return The working pressure of the gas pressure regulator is too high or too low 2022-08-31 09:15:23.238

This is mainly due to improper adjustment of the rated pressure of the pressure regulating valve. It can be solved by adjusting the adjusting bolt of the pressure regulating valve. The rated pressure can be increased by screwing the adjusting bolt downwards; otherwise, the working pressure can be decreased.

Question What should I do if the gas pipeline ball valve leaks? 2022-08-31 09:14:11.756

There are many reasons for internal leakage of ball valves. First of all, the reasons for internal leakage of the valve during the construction period, such as improper transportation and hoisting, cause the overall damage of the valve and cause internal leakage of the valve.

Question Coil Warranty Principle of Solenoid Valve 2022-08-31 09:10:13.208

In principle, the coil of the solenoid valve is not guaranteed, which is the basic principle of this industry.

Question The reason why the solenoid valve burns the coil 2022-08-31 09:10:00.075

Is the solenoid valve coil dripping with water? Conventional coils are easy to burn out in water

Question The breathing hole of the gas pressure reducing valve is blocked and the pressure cannot be adjusted 2022-08-31 09:05:13.228

Without paying attention to daily maintenance and cleaning, the gas pressure reducing valve is contaminated with debris, so that the small round hole with a diameter of about 1mm in the upper casing is blocked. This small round hole is a breathing hole,

Question The flow or pressure of the gas pressure reducing valve is abnormal 2022-08-31 09:03:59.061

The main reason is that it has been used for a long time, causing the rubber sealing ring to expand and deform. If it is deformed, the glue should be replaced.

Question What should be paid attention to when using gas self-closing valve 2022-08-11 15:31:23.242

1. When using the gas self-closing valve, whether it is to open the valve or close the valve, all the valves need to be opened or closed, so as to ensure that the self-closing valve can fully exert its effect.

Question What are the main functions of the gas self-closing valve? 2022-08-11 15:30:48.078

1. With pipeline gas supply pressure monitoring function. When the pipeline gas supply pressure of the gas system has an underpressure fault or an overpressure fault, the self-closing valve will automatically close the valve to avoid the expansion of the fault.
