Abstract

The present invention provides a pressure release testing device which comprises a sign post which is installed at one end of an outer cover and is embedded into the outer cover. One end of the sign post is tightly connected to a membrane disc. The outer cover is internally equipped with a spring, and two ends of the spring are embedded into the inner surface of the outer cover. The spring is installed at one side of the membrane disc which is installed at one side of a sealing rubber ring. The sealing rubber ring is installed at one end of a switch which is arranged at the surface of the outer cover. The switch is installed at one side of a positioning handle which is installed at one end of a guide post and is embedded into the outer part of the guide post. The guide post is installed at one side of a side rubber ring which is installed at one side of a valve seat. The device has the advantages of compact structure and long life, the magnitude in pressure release can be controlled, the rapid positioning is achieved, the pressure detection is carried out, and the device has good social and economic effects and is suitable for promotion and use.

Description

technical field [0001] The invention relates to a release inspection device, in particular to a pressure release inspection device, which belongs to the technical field of calibration. Background technique [0002] The pressure release test device is widely used in the special equipment for the fixed value of the gas relay flow rate, volume value, sealing pressure, and the opening and closing of the pressure release valve. During operation, due to the effects of oxygen, high temperature, high humidity, sunlight, strong electric field and impurities, the performance of the machine itself will gradually deteriorate, making effective detection impossible. [0003] The pressure release inspection device adopts advanced micro-control technology. By detecting the high-precision pressure sensor and simulating the internal failure of the transformer, the instantaneous blasting pulse pressure method calculates the fixed value of the flow rate, so as to achieve the heavy gas protectio...
