Detection device applied to automatic detection of performance of pipeline gas self-closing valve

Abstract

The invention discloses a detection device for automatically detecting the performance of a pipeline gas self-closing valve, and the detection device comprises a working rack, and a plurality of groups of tool positions, a gas inlet detection device and a gas outlet detection device which are disposed on the working rack, and the plurality of groups of tool positions support and are fixedly provided with the self-closing valve. A plurality of groups of tool positions are arranged, detection work can be carried out on the plurality of groups of tool positions at the same time, each tool position is an independent subsystem and does not influence each other, the working efficiency is greatly improved, the air inlet detection device is in butt joint with an air inlet of the self-closing valve, and the air outlet detection device is in butt joint with an air outlet of the self-closing valve. The air inlet detection device comprises an air inlet sealing pressure head, an air inlet pressure head fixing seat and a first air cylinder, the air inlet sealing pressure head is driven by the first air cylinder to stretch out and draw back, front-back movement of the air inlet sealing pressure head is achieved, and then contact and separation of the air inlet sealing pressure head and the self-closing valve workpiece are achieved.

Description

technical field [0001] The invention relates to the technical field of pipeline gas self-closing valves, in particular to a detection device applied to automatic performance detection of pipeline gas self-closing valves. Background technique [0002] Pipeline gas self-closing valve, referred to as self-closing valve, pipeline gas self-closing valve is installed on the pipeline of low-pressure gas system. When the gas supply pressure of the pipeline is under-pressure or over-pressure, it can be closed automatically without electricity or other external power. Devices that are manually opened. The basic principle of the pipeline gas self-closing valve is to magnetize the permanent magnet material according to the design requirements to make a multi-pole permanent magnet linkage mechanism with permanent memory, to identify the change of the gas pressure parameter passing through it, and automatically when it exceeds the safe setting range. Close the valve and cut off the gas s...

Problems solved by technology

[0003] At present, in the self-closing valve manufacturing industry, the commonly used testing equipment can only test the airtightness of the self-closing valve alone; in addition, the existing testing equipment generally uses manual reset, which is difficult to ensure the accuracy of the self-closing valve reset cover. journey

[0004] In addition, the existing self-closing valve detection device cannot detect the flow and air tightness at the same time, so the flow and air tightness of the self-closing valve need to be measured separately. The airtightness of the self-closing valve can only be detected by a non-resistance detection device, which is cumbersome to operate and affects the efficiency of self-closing valve detection
