Introduction to the role of pressure relief holes in American standard gate valves

Date: [2019-08-09] Click rate:

The American standard gate valve can be widely used as a regulating and shut-off device in the pipelines of tap water, sewage, construction, petroleum, chemical industry, food, medicine, textile, electric power, shipping, metallurgy, energy system, etc.


The role of pressure relief hole in American standard gate valve:

Can prevent abnormal boost. After the shutter is closed, there is a low temperature medium in the cavity of the valve. Over time, these media will absorb heat from the atmosphere and vaporize. After gasification, its volume expands sharply, generating extremely high pressure, damaging the valve and causing danger. In order to prevent abnormal pressure rise, setting pressure relief holes on the gate is one of the measures adopted by the low-temperature American standard gate valve to ensure safety.

The American standard gate valve overcomes the defects such as poor sealing and rust of the general gate valve. The elastic seat sealing gate valve uses the compensation of the slight elastic deformation generated by the elastic gate plate to achieve a good sealing effect. Significant advantages such as longevity.
