Abstract

The invention discloses a valve airtightness test bench, which relates to a detection device and comprises a bench body. An air source device is fixedly mounted in the bench body, a first pressing block and a driving structure are fixedly mounted on the air source device, and a second pressing block capable of being driven by the driving structure to linearly reciprocate relative to the first pressing block is fixedly mounted at the action end of the driving structure. Air holes are formed in the first pressing block and the second pressing block respectively, the air holes in the first pressing block are connected with an air source device through a first guide pipe, a normally-closed first two-position three-way electromagnetic valve is installed on the first guide pipe, and a first airflow observation device is further communicated with the portion, between the first two-position three-way electromagnetic valve and the corresponding air holes, of the first guide pipe through a second guide pipe. A normally-closed second two-position three-way electromagnetic valve is further installed on the second guide pipe, an air hole in the second pressing block is connected with a second airflow observation device through a third guide pipe, and a third two-position three-way electromagnetic valve is installed on the third guide pipe. Valve airtightness detection can be effectively carried out.

Description

technical field [0001] The invention relates to a detection device, in particular to a valve air tightness test device. Background technique [0002] Before the valve leaves the factory, it needs to test its air sealing parameters, and the valve can only leave the factory after the test valve has no leakage. At present, most of the existing equipment has complicated structure, cumbersome operation, and many testing links. It is difficult for operators to get started, and the work efficiency is low, which makes it extremely difficult to test a large number of valves, especially the air tightness test. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a valve airtightness test bench to solve the technical problem of difficult valve airtightness test in the prior art. [0004] The present invention is achieved through the following technical solutions: [0005] A valve airtightness test benc...
