Problems solved by technology

[0004] However, when this automatic quick connector is in use, the gas can only be charged from the air inlet joint, and it is impossible to judge whether it is the leakage of the pipe fitting or the air intake end; if the gas is charged from the locking joint, the joint will be damaged, and the inflation Joint structure is complex

Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] Such as figure 1 and figure 2 As shown, a quick connector for leakage detection includes a connector body with a housing chamber inside, and an air inlet connector is provided at one end of the connector body; a locking part is provided in the housing chamber, and the locking part There is a ventilation channel communicating with the air inlet joint; the locking part realizes the locking state through the backflow of the air pressure in the accommodating cavity. The locking part includes a piston 10 connected to the intake joint with a vent channel in the middle, several clamping blocks 2 and clamping block mounting seats 4 distributed circumferentially outside the intake joint; the piston 10 is movably arranged in the housing In the cavity; there is a gap between the lower part of the piston 10 and the inner wall of the joi...

Abstract

The invention relates to a quick joint used for leakage detection. The quick joint comprises a joint main body with an accommodating cavity therein, wherein one end of the joint main body is equippedwith a gas inlet joint; a locking part is arranged in the accommodating cavity; a ventilating channel is arranged between the locking part and the gas inlet joint in a communication mode; and the locking part realizes a locking state through gas-pressure reflow in the accommodating cavity. The quick joint has the beneficial effects that: gas can be directly introduced in from a tube while leakagedetection is performed on the tube by the quick joint, the tube is locked by gas-pressure reflow, the structure is simple, operations are convenient, and the possibility of leaking gas from the gas inlet end is eliminated.

Description

technical field [0001] The invention relates to a pipeline quick joint, in particular to a quick joint used for gas leakage detection. Background technique [0002] In actual production, when the pipeline needs to be inflated with gas to detect leaks or stored under pressure with gas, quick connectors are usually required. Especially in the fields of air conditioners or refrigerators of household appliances, it is necessary to fill liquid or gas to the inside of the product as functional parts, so these parts need to be tested for leaks, and the quick connector is used to connect the pipe fittings to the inflatable device and inflate them to detection. In the prior art, a hand-operated quick connector is generally used to open and insert the pipe fitting by pulling the handle, and then pull the handle to compress the pipe fitting for detection. With such a quick connector, when the handle presses the fitting, it is impossible to judge whether it is pressed in place. If it ...
