Problems solved by technology

[0002] Before the product leaves the factory, a series of tests need to be carried out on the product. Among them, for some valves, pipes and other products, the tightness test is especially important. The existing tightness test device has a complicated structure and is not easy for operators to operate, and the existing The airtightness test is often performed by filling the closed cavity with gas. If the gas is filled too much, it will explode, and there are certain safety hazards.

Abstract

The invention discloses a sealing performance testing device and method, and the device comprises a machine platform which is provided with an object placement groove. A sealing upper cover which is used for closing the object placement groove is disposed above the object placement groove. The device also comprises a sealing assembly which is disposed in the object placement groove, and comprises a sealing ring and a drive cylinder in transmission connection with the sealing ring; a positioning assembly which is disposed in the object placement groove, and comprises a support with a stepped surface; a vacuum pumping apparatus which is disposed in the object placement groove and is used for the vacuum pumping of a sealed cavity formed by the object placement groove and the sealing upper cover; and a detection assembly which is disposed in the object placement groove and comprises a first air pressure inductor, wherein the first air pressure inductor is used for detecting the air pressure value of the sealed cavity formed by the object placement groove and the sealing upper cover. According to the invention, the device is simple in structure and is low in cost. The method is high in safety factor, is good in testing efficiency, and is high in testing precision.

Description

technical field [0001] The invention relates to a mechanical fixture, in particular to a sealing test device and a test method. Background technique [0002] Before the product leaves the factory, a series of tests need to be carried out on the product. Among them, for some valves, pipes and other products, the tightness test is especially important. The existing tightness test device has a complicated structure and is not easy for operators to operate, and the existing The airtightness test is often carried out by filling the closed cavity with gas. If the gas is filled too much, it will explode, and there are certain safety hazards. [0003] Therefore, a sealing testing device and testing method with simple structure, low cost, high safety factor and high precision need to be proposed urgently. Contents of the invention [0004] In order to solve the above technical problems, the present invention proposes a sealing test device and a test method. The test device has a s...
