Abstract

The invention relates to an airtight valve airtightness detection platform. The airtight valve airtightness detection platform comprises an air compressor, a vacuum pump, a plenum chamber, an airtight valve and a reducer pipe, the reducer pipe is mounted on one side of the plenum chamber, a first ball valve, a second ball valve, a third ball valve and a fourth ball valve are mounted on the other side of the plenum chamber sequentially, the airtight valve is mounted at the end of the reducer pipe, the air compressor is mounted at the end of the first ball valve, the vacuum pump is mounted at the end of the second ball valve, a first pressure sensor is mounted at the end of the third ball valve, and a second pressure sensor is mounted at the end of the fourth ball valve. The airtight valve airtightness detection platform is simple in structure, good in measurement effect and quite high in practicality.

Description

technical field [0001] The invention relates to the technical field of industrial testing, in particular to an airtight testing platform for airtight valves. Background technique [0002] Airtight valves are responsible for the airtight performance of the project. At present, the protective airtight doors are produced and processed according to the requirements of the design drawings. Due to the large number of manufacturers and the variety and complexity of equipment types, there are relatively few detection methods and detection equipment in the production process. Product quality and performance are difficult to be effectively guaranteed without effective quality supervision, so that there are great hidden dangers in the use of airtight valves. Contents of the invention [0003] The object of the present invention is to provide an airtightness detection platform for airtight valves, through which the airtightness performance of airtight valves can be detected, providing...
