Hard seal corrugated pipe rapid connector with detection function

Abstract

The invention discloses a hard seal corrugated pipe rapid connector with a detection function. The connector comprises a rapid connector body, a thread head, a seal ring, a first clamping ring and a second clamping ring, wherein the rapid connector body and the thread head are mutually matched. The rapid connector body comprises a thread sleeve and a bottom sleeve connected to one end of the thread sleeve. A detection hole is formed in the outer circumference of the bottom sleeve, and an internal thread is arranged on the inner circumferential wall of the thread sleeve. The thread head comprises a thread head hexagonal prism, a first thread rod and a second thread rod, the end of the first thread rod is provided with an arc face, the top of the arc face is provided with a positioning ring,the first thread rod is matched with the internal thread on the inner circumferential wall of the thread sleeve, the positioning ring is used for being inserted into a corrugated pipe to be connectedto achieve positioning, the first clamping ring and the second clamping ring are located on the two sides of the positioning ring correspondingly and used for clamping the corrugated pipe to be connected to the outer circumferential wall of the positioning ring, the inner diameter of the bottom sleeve is smaller than that of the thread sleeve, a step portion is formed at the combined portion between the thread sleeve and the bottom sleeve, and the step portion is provided with the seal ring.

Description

technical field [0001] The invention relates to the technical field of quick joints, in particular to a hard-sealed bellows quick joint with a detection function. Background technique [0002] A quick connector is a connector that can be connected or disconnected without tools. Quick connectors can be divided into: quick connectors for air, quick connectors for oxygen fuel gas, quick connectors for gas and liquid, quick connectors for oil pressure, quick connectors for inert gas, quick connectors for cooling water and oil, and semiconductor quick connectors. [0003] During the use of the bellows quick connector in the prior art, since the trough of the joint body adopts an inclined surface, the bellows and the joint body will move and loosen after a long time of use, which may cause air leakage, especially When used in flammable and explosive systems such as gas pipelines, poor sealing effect will cause serious consequences.

Problems solved by technology

[0003] During the use of the bellows quick connector in the prior art, since the trough of the joint body adopts an inclined surface, the bellows and the joint body will move and loosen after a long time of use, which may cause air leakage, especially When used in flammable and explosive systems such as gas pipelines, poor sealing effect will cause serious consequences

And because there is usually a yellow coating on the outside of the corrugated pipe, it is not easy to find when there is an air leak, which adds to the safety hazard.

In addition, during the use of the bellows quick connector in the prior art, the connected bellows are prone to move inside the quick connector, thereby affecting the sealing performance
