Valve airtightness detection equipment

Abstract

Valve airtightness detection equipment disclosed by the present invention comprises a machine body and a reservoir formed on the machine body, a lifting platform is arranged above the reservoir, driving members are symmetrically arranged on the lifting platform, each driving member is connected with a sealing member, one of the sealing members is connected with an air inlet pipe, a detection platform is rotatably arranged at the position, between the two sealing pieces, of the lifting platform through a rotating shaft, a detection station which is used for placing a valve and corresponds to the sealing pieces is formed on the detection platform, and the axis of the rotating shaft is parallel to the symmetric line of the two sealing pieces. The detection equipment has the following advantages and effects that the detection equipment can detect valves with different models and large outline differences, the operation is simple and convenient, the detection efficiency is high, and the universality of the equipment is better; and the equipment can also realize real-time storage of the detection data, so that later viewing is facilitated.

Description

technical field [0001] The invention relates to a valve testing device, in particular to a valve air tightness testing device. Background technique [0002] In the process of valve production and processing, in order to ensure the production quality of the valve, the air tightness test of the assembled valve must be carried out before the valve is sold. Only when there is no leakage of the valve and the sealing level specified by the state is a qualified product, and subsequent product sales can be carried out. [0003] When testing the valve in the existing testing equipment, the valve to be tested is first placed in the testing station, and the seal is driven by the driving part to seal the two ends of the valve tightly, and then high-pressure gas is introduced into the valve. Check the air tightness of the valve to see if there is a leak in the valve. [0004] Due to the different shapes and contours of different types of valves and there is no certain standard, it is d...

AI Technical Summary

Problems solved by technology

[0004] Because the outlines of different types of valves vary greatly and there is no certain standard, it is difficult for the existing testing station to match various valves with different outlines, making it difficult for the valve to be placed in a horizontal state when placed in the testing station.

When the placed valve has a large inclination, a large gap is easily generated between the seal and the end face of the valve, resulting in leakage

This greatly affects the detection efficiency of the valve, and also leads to poor versatility of existing detection equipment
