Steel-plastic conversion part air tightness detection device

Abstract

The invention discloses a steel-plastic conversion part air tightness detection device. Supports are symmetrically arranged above two sides of a pool and with the center line of the pool as a symmetric axis; a piston cylinder is fixedly connected onto the support, a piston rod of the piston cylinder extends out downwardly, and the tail end of the piston rod is fixedly connected with a sealing block; the pool is internally provided with a V-type plate for fixing the steel-plastic conversion part, the support is parallel with one corresponding side of the V-type plate or in the same plane, air holes are arranged on one surface, facing the pool, of the sealing block, and the air holes are connected with an air port of the steel-plastic conversion part; and a test air pipe is connected onto the sealing block, one end of the test air pipe is communicated with the air hole through an inner pipeline of the sealing block, and the other end of the test air pipe and the piston cylinder are connected with an air source respectively. Both a straight steel-plastic conversion part and a bent steel-plastic conversion part can be tested, the test is convenient and quick, the test efficiency is improved, and the labor time is saved.

Description

technical field [0001] The invention relates to the technical field of air-tightness detection, in particular to an air-tightness detection device of a steel-plastic conversion part. Background technique [0002] At present, gas pipelines have been widely used in many living quarters and families, bringing convenience to the life of each family. When laying gas pipelines, PE pipes need to be laid underground, and seamless steel pipes need to be laid for the parts that leak out of the ground; therefore, more steel-plastic conversion parts are needed, and the air tightness testing of these steel-plastic conversion parts is very important. important. [0003] The original steel-plastic conversion parts testing device such as figure 1 As shown, it includes connecting rod A, the steel-plastic conversion part to be tested is sleeved on the connecting rod A, and sealing blocks B1 and B2 are fixedly connected to both ends of the connecting rod A, and the sealing blocks B1 and B2 s...

AI Technical Summary

Problems solved by technology

The detection device can better detect the air tightness of the steel-plastic conversion parts, but because the connecting rod of the device is made of metal, the texture is relatively hard and cannot be bent, so this detection device cannot detect the bent pipe; For the pipe, the straight pipe can only be tested when the bent pipe is still in the state of the straight pipe. After the inspection, the qualified straight pipe can be processed into a bent pipe; however, the bent pipe will be rubbed in the later processing process, resulting in defective products. increased chance of

In addition, this detection device can only detect one by one, the detection speed is slow, and the work efficiency is too low; and each test needs to rotate the nut, the work is cumbersome, the workload is heavy, and the workers are very hard to test.
