Problems solved by technology

If the airtightness of the valve core is not good, it will directly affect the working performance of the valve, and sometimes even cause safety accidents
[0003] In the past, when people tested the airtightness of the valve core, most of them used a manual compression testing equipment. This manual compression testing equipment has a complex structure and cumbersome operation. , the size of the pressing force generated each time is unstable, which leads to unstable product quality inspection results

Abstract

The invention relates to a valve element airtightness testing device and belongs to the technical field of testing clamps. The valve element airtightness testing device is characterize by comprising a pressing device (1), wherein the pressing device (1) comprises a bottom plate (1.1), a top plate (1.2) and a movable beam (1.3); the top plate (1.2) is provided with an air cylinder (3); a pluralityof guide posts (2) are arranged between the bottom plate (1.1) and the top plate (1.2); the movable beam (1.3) is sleeved on the guide posts (2); a pressure block (4) is arranged at the bottom of themovable beam (1.3); a base (5) is arranged on the bottom plate (1.1); and a sealed barrel (6) is fixed below the pressure block (4). The valve element airtightness testing device can provide stable and adjustable pressing force, so the airtightness of the valve element can be tested more accurately, and the test efficiency is improved; and the operation is convenient, the structure is simple, thetest efficiency is high, and the manual operation intensity is lowered.

Description

technical field [0001] The invention relates to a valve core air tightness detection device, which belongs to the technical field of inspection fixtures. Background technique [0002] In current production and life, people use valves as switches for fluids in pipelines. With the improvement of people's demand, the precision of various hydraulic parts is also continuously improved, so the structure of the internal valve core of various valves is becoming more and more complex, and the precision requirements are getting higher and higher. The airtightness of the valve core usually needs to be tested before it is used. If the air tightness of the valve core is not good, it will directly affect the working performance of the valve, and sometimes even cause safety accidents. [0003] In the past, when people tested the airtightness of the valve core, most of them used a manual compression testing equipment. This manual compression testing equipment has a complex structure and c...
