  3. The diaphragm compressor safety valve is...

The diaphragm compressor safety valve is not careful and will be less and less safe

The diaphragm compressor safety valve is not careful and will be less and less safe

一. Under which condition can the diaphragm compressor safety valve not be applied

Whether an article is useful, sometimes need to see the area that it is in, if the use is not very good, it can be a very big security risk. Diaphragm compressor safety valve is such a commodity. So in which condition can the diaphragm compressor safety valve not be applied?

1. The pressure will continue to grow, and the release rate of the safety valve is lower than that of the pressure.

2. When there are not optimistic regulations on sealing properties.

3. The raw materials in the vessel will make the safety valve invalid, such as the raw materials in the oil tank with a lot of solid particles, the safety valve after the seat will cause the sealing is not tight.

4. When the raw materials in the vessel have toxic or other characteristics that block information security.

The above conditions should not be applied alone safety valve, must be used blasting plate or safety valve and blasting plate composition application.

二. The diaphragm compressor safety valve must be verified on time

Diaphragm compressor safety valve belongs to the valve class, its working mechanism is, when the diaphragm compressor or the pipeline medium pressure rises above the standard value, will discharge medium to the system to prevent the pipeline or machine equipment medium pressure exceeds the required value of the gate valve, when the control pressure does not exceed the standard value, can be the diaphragm compressor work and life safety has a main maintenance effect.

Verification method of safety valve of diaphragm compressor:

1. Verification table offline verification: it is necessary to put the safety valve machine and equipment on the verification table, and then apply the verification medium to make the safety valve open, by viewing the pressure gauge to determine the open pressure. But this kind of method can not fully consider the back pressure safety valve and high temperature or ultra-low temperature medium safety valve verification.

2. Online instrument and equipment verification: is through the external force on the effect of the safety valve down the torsion spring interaction force measured, can be used to calculate the opening pressure of the safety valve, this method is generally not affect the production, the system pressure does not need to modify, the inspection rate is relatively very fast. And it is very convenient and convenient, but this method can not test the sealing characteristics of the safety valve.

3. Variable pressure jump method verification: it is to put the safety valve into the machine and equipment in the system, the system human factor variable pressure, until the safety valve jumped, to check the opening pressure of the safety valve, this kind of check method to the protruding surface of the safety valve harm is relatively large, the actual operation of the risk factors are also relatively large.
