Metal pipe airtightness tester

Abstract

The present invention discloses a metal pipe airtightness tester which comprises a workbench, the bottom of the workbench is fixedly provided with a support frame, one side of the front surface of the workbench is provided with a high-pressure detection area, the other side opposite to the high-pressure detection area is provided with a low-pressure detection area, and two sides of the high-pressure detection area and two sides of the low-pressure detection area are fixedly provided with driving mechanisms. A sealing pressurization pipe sleeve is fixedly installed at the end of the driving mechanism on one side of the low-pressure detection area, a pressurization opening is formed in the upper end of the sealing pressurization pipe sleeve, and sealing assemblies are fixedly installed on the two sides of the high-pressure detection area and the end of the driving mechanism on the other side of the low-pressure detection area at equal intervals. According to the scheme, the driving mechanism, the sealing assembly and the sealing pressurizing pipe sleeve are matched with one another, so that the equipment has the functions of high-low pressure dry-type testing, simultaneous batch detection of air tightness of metal pipes at one time, automatic feeding and blanking, expansion type sealing for sealing, and solving of the problem of frequent breaking of sealant; especially, the low-voltage detection area is utilized to realize the sensitive detection effect of slight leakage in a short time, and the blank in the field in China is filled.

Description

technical field [0001] The invention relates to the technical field of automatic testing of the sealing performance of metal pipes, in particular to an airtightness tester for metal pipes. Background technique [0002] Stainless steel pipe is a hollow long round steel, mainly widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipelines and mechanical structural components. In addition, when the bending and torsional strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used as furniture and kitchen utensils, etc. Metal pipes need to be tested for air tightness after production and processing; [0003] At present, the general metal pipe test is mainly based on single-piece test by immersion in water, which is slow and inefficient. During the test, the sealant at both ends is easily cut by the nozzle. Sometime...

Problems solved by technology

[0003] At present, the general metal pipe test is mainly based on single-piece test by immersion in water, which is slow and inefficient. During the test, the sealant at both ends is easily cut by the nozzle. Sometimes it is not scientific enough to change the sealant several times a day, which seriously affects the airtightness.
