Step 1: Check whether the solenoid valve is normal, whether the coil is worn out or in poor contact, and whether the spool of the solenoid valve is stuck. Repair method: Replace the coil. Clean up the stuck things on the solenoid valve. Replace the solenoid valve if the above method is useless. Step 2: Check whether the pneumatic actuator works normally, such as cylinder piston blow-by, cylinder body and end cover or shaft leakage, etc. Repair method: Disassemble the actuator and check whether the seal is damaged. Whether the surface of the cylinder inner hole is damaged. Replace the damaged seal ring, replace the piston, or the cylinder. Step three check whether there is something inside the valve core or valve plate stuck. Maintenance method: cleaning miscellaneous

Due to the principle of medium, the valve will occasionally be blocked or stuck in the process of use, and cannot operate normally. To avoid this problem, Wuhan Xiete Valve Technology Co., Ltd. has taken countermeasures and summarized the following methods for your reference only: rust, welding slag, slag, etc. in the pipeline of 1. cleaning method will cause blockage or jam in the hole of each part of the valve, cause the valve core, guide surface, sealing surface to produce indentation, deformation, etc., which is the most common fault. When this happens, the device should be removed in time for cleaning, and the dirt should be cleaned; if the sealing surface is damaged, it should be ground; at the same time, the bottom plug should be removed.

The valve sealing function requirements, to prevent leakage angle. According to the different parts and degree of the leakage, the leakage of the valve is different, so it is necessary to put forward different methods. There are two reasons for leakage, one is the most important factor affecting the sealing performance, that is, there is a gap between the sealing pair, and the other is the pressure difference between the two sides of the sealing pair. The principle of valve sealing is also analyzed from four aspects: liquid sealing, gas sealing, leakage channel sealing principle and valve sealing vice. 1. The tightness of the liquid The tightness of the liquid is through the viscosity and surface tension of the liquid

Pneumatic valve is a kind of valve driven by compressed air. When selling pneumatic valves, only clear specifications, categories and working pressure can generally meet the purchasing needs of customers. Start valve can generally be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. Pneumatic valve is a kind of high-quality valve with convenient operation and low failure rate. In daily use, we need to develop a good habit of valve inspection and maintenance. Regular inspection and maintenance, the equipment runs more smoothly. So in the daily inspection of pneumatic valves, how should the specific work be carried out
