Description

Semi-automatic air measuring valve

Technical Field

The utility model relates to a valve body gas tightness detection area, in particular to semi-automatic air measuring valve.

Background

The basic detection principle of the valve body air tightness detection device is a pressure drop method (pressure drop method), also called a pressure attenuation method, which is to pressurize by inflating the interior of a valve body product and judge whether the product leaks or not by detecting the change of quantitative air pressure filled in the valve body in real time;

the working principle of the valve body airtightness detection equipment is that through three main processes of constant-pressure air inlet, balance and detection, a leakage value of the valve body airtightness detection equipment is obtained through a series of sampling, calculation and analysis by a sensor and a system in the valve body airtightness detection equipment, and OK or NG is judged according to the data and the set allowable leakage amount; the common air valve measuring device needs different devices for fixing different valve bodies, is poor in compatibility, has more times of tool replacement, and causes lower air measuring efficiency of the valve bodies.
