Detection equipment of performance of automobile one-way valve

Abstract

The invention relates to detection equipment of the performance of an automobile one-way valve. The detection equipment comprises a machine base. A detection position is reserved on the machine base. A detection device is arranged at the detection position and comprises an intake tube blocking mechanism positioning and blocking an intake tube of the one-way valve, an exhaust pipe blocking mechanism positioning and blocking an exhaust tube of the one-way valve and a valve fixing mechanism fixing the one-way valve. The intake tube blocking mechanism comprises an intake tube blocking base, and the intake tube blocking base is provided with an intake tube control air channel leading air into the intake tube of the one-way valve or exhausting air out of the intake tube of the one-way valve. The exhaust pipe blocking mechanism comprises an exhaust pipe blocking base, and the exhaust pipe blocking base is provided with an exhaust tube control air channel leading air into the exhaust tube of the one-way valve or exhausting air out of the exhaust tube of the one-way valve. By means of the detection equipment of the performance of the automobile one-way valve, automatic detection of the sealing performance and the antiknock performance of the automobile one-way valve is achieved. The detection equipment has the advantages that the detection efficiency is high and the detection result is reliable.

Description

technical field [0001] The invention relates to a valve detection device, in particular to a performance detection device for a one-way valve of an automobile for detecting the sealing performance and antiknock performance of the one-way valve of the automobile. Background technique [0002] Automobile check valve is an important part of vacuum booster, which is usually made of plastic; such as figure 1 As shown, its main structure includes a valve body 91, a valve cover, a valve seat and a valve core. The air pipe 94 and the valve body 91 have an annular fixing seat 96 for assembling the valve cover, and the annular fixing seat forms an annular flange 96 outside the valve body 91 . [0003] The sealing test of the existing automobile check valve adopts manual inspection, which is not only inefficient, but also has a high error rate and poor reliability; and the automobile check valve is a plastic injection molded part. Due to processing reasons, there is usually uneven wal...

Problems solved by technology

[0003] The sealing test of the existing automobile check valve adopts manual inspection, which is not only inefficient, but also has a high error rate and poor reliability; and the automobile check valve is a plastic injection molded part. Due to processing reasons, there is usually uneven wall thickness, and some If the wall thickness is too thin, it is prone to bursting, so its strength (anti-explosion) performance is also an important indicator of the reliability of the check valve. The strength of the check valve for automobiles can only be tested through the visual inspection of the inspector, and the detection effect is poor. defect

[0004] According to the current situation, the existing methods and equipment for testing the sealing performance of valves are all based on sealing the mouth of the valve and then performing corresponding testing. However, due to the differences in the types of valves, the existing testing equipment is not suitable for Detection of one-way valves in automobiles
