Abstract
The invention discloses a four-loop protective valve opening pressure detecting device which comprises a bottom plate capable of being fixed to a rack. Four cylinders are fixed to the bottom plate through fixing assemblies respectively. Each cylinder is correspondingly arranged at a port of a four-loop protective valve and provided with an end cap. Air is injected through an air inlet of each cylinder so that the end cap connected with the cylinder can stretch forwards to block the corresponding port of the four-loop protective valve. The invention further provides a four-loop protective valve opening pressure detecting method. The four-loop protective valve opening pressure detecting device is high in testing efficiency and testing accuracy when testing the opening pressure of the four-loop protective valve. The fixing assemblies are simple in structure, practical and high in clamping accuracy. Compared with a testing method in the national standard, the four-loop protective valve opening pressure detecting method is rapid and accurate in testing and high in accuracy.
