As far as the entire air compressor is concerned, the safety valve seems to be insignificant, but its role cannot be ignored. Once the safety valve fails, it will affect the normal operation of the air compressor, and even equipment accidents as well as personal injury. Therefore, an air compressor that does not have a safety valve or a defective safety valve is absolutely prohibited. Listed below are the common failures of spring-loaded safety valves, analysis of simple causes, and exclusion methods.
First, the safety valve and its closed mechanism vibration 1, due to the air compressor exhaust pipe vibration caused by the strong vibration of the valve.
2. The cross section of the safety valve pipe is smaller than the cross section of the safety valve or the cross section is reduced due to the blockage, so that the safety valve “eats†and vibration occurs.
3, due to the safety valve through the capacity of excessive vibration.
4. Due to the small cross section of the safety valve discharge passage, the pressure on the back of the valve plug is increased, causing the opened valve plug to fall to the valve seat prematurely. As the compressed air discharge valve opens again. In this way, repeated opening and closing are performed at a great frequency to cause vibration of the safety valve.
Second, safety valve leakage 1, due to improper manufacturing, improper assembly.
2, the installation tilt, so that the valve and the valve seat sealing surface movement, as well as lax contact.
3, the two ends of the spring are not parallel or skew when assembled; the lever and fulcrum of the lever type safety valve are skewed, so that the contact surface pressure of the valve core and the valve seat is uneven.
4. The sealing surface between the valve plug and the valve seat is damaged.
5, excessive mechanical impurities fall on the sealing surface, the valve plug up. The connection thread is damaged or not tight.
Third, the safety valve does not open to the specified pressure 1, the safety valve adjustment opening pressure is higher than the specified value; the lever-type safety valve weight hammer is not fixed, to the direction of leaving the fulcrum.
2. The cross section of the safety valve tube is too small or blocked so that the pressure in the safety valve is lower than the pressure in the exhaust pipe of the compressor.
3, spool and valve seat due to dirt and was stuck.
4. The lever of the lever type safety valve is stuck or the lever shaft is rusty.
5. In the northern cold season, the outdoor safety valve freezes.
4. When the safety valve is less than the prescribed opening pressure, the opening or action is more frequent. 1. The opening pressure of the safety valve adjustment is lower than the specified value; during the operation, the loosening of the adjustment thread or the weight of the lever-type safety valve moves in the direction of the fulcrum.
2. The elasticity of the spring is small or permanent deformation occurs and the elasticity is reduced.
3. The opening pressure of the safety valve adjustment is lower than the opening pressure adjusted by the load regulator. When the compressed air consumption changes frequently, the load regulator does not act and the safety valve frequently operates.
4. The opening pressure of the safety valve adjustment is too close to or even equal to or lower than the working pressure of the air compressor. The safety valve will frequently operate during operation.
2) Bale-discharging:"turn-out","push-out","forward-out" .
3) No footing bolts needed in installation;diesel engine can be power.
In order to prevent accidents due to high pressure in the air compressor, the working pressure should not exceed the specified value, so a safety valve must be installed on the pipeline behind each stage of the air compressor. There are two types of safety valves commonly used on air compressors: spring type safety valves and lever type safety valves. Because the former has a relatively compact structure, it is often used. Safety valves should generally be installed vertically in places where pressure fluctuations, such as air tanks, oil-water separators or coolers, are minor.
