Quick plug for air tightness test

Abstract

The invention discloses an air tightness test quick plug, relates to the technical field of test instrument accessories, and solves the problems that when an air tightness test is carried out, an air pipe test connector needs to be screwed to be in butt joint with a test instrument, the operation is tedious, and the detection progress is affected. The air tightness test quick plug comprises a plug-in female head, a positioning plug-in hole is formed in the bottom end of the plug-in female head, two symmetrically-distributed locking clamping grooves are formed in the bottom face of the plug-in female head, anti-disengaging clamping holes are formed in the inner walls of the locking clamping grooves, and the two locking clamping grooves are located on the two sides of the positioning plug-in hole respectively. According to the invention, through the arrangement of the plug-in female head, the magnet protection cover, the plug-in male head, the pipe pressing nut and the butt-joint locking mechanism, the air pipe test joint can be quickly in butt joint with equipment during an air tightness test, the operation time is saved, the test progress is effectively shortened, and the air pipe test joint is ensured not to fall off in the test process.

Description

technical field [0001] The invention relates to the technical field of test instrument accessories, in particular to an airtight test quick plug. Background technique [0002] With the rapid development of society and economy, the air tightness test is an experiment used to check the air tightness of the device, mainly to check whether there is leakage in each connection part of the container, and the toxicity of the medium is extremely, highly hazardous or not allowed by the design. The pressure vessel with slight leakage must be tested for air tightness. The quick plug for air tightness test refers to the fitting that connects the trachea with the testing instrument. [0003] However, when the existing air tightness test is performed, the trachea test connector needs to be twisted to connect with the test instrument, which is cumbersome to operate and affects the testing progress; therefore, it does not meet the existing requirements, and we propose an air tightness test. ...
