The airtightness tester standard tank is used to test the airtightness performance of materials, and its principle of action is mainly based on the measurement principle of pressure changes. During testing, the airtighter seals the standard can outside the sample, applies a certain pressure to the standard can, and records the pressure changes inside the standard can.
It mainly seals various internal holes, pipe holes, etc., and can form effective seals on sealing surfaces, machined surfaces, or partially cast surfaces.
A leak free three-way valve is a type of valve used in conjunction with air tightness testing. It can be used as a three-way valve, as well as a leak free distribution valve and a leak free selection valve.
Compressed air drive, automatic locking structure. Widely used in the refrigeration and new energy industries, such as heat exchangers, pressure vessels, instruments and meters, motor control cooling water plates, etc
