Abstract

The invention provides a quick joint of a corrugated pipe for gas, which belongs to the technical field of gas and solves the problems that the prior quick joint of the corrugated pipe needs deformation and has trouble in installation during quick installation. The quick joint of the corrugated pipe for gas comprises a corrugated pipe, a locking screw and a joint with a connection hole, wherein the corrugated pipe is sleeved with a seal washer and a clamping sleeve which can be clamped in the trough of the corrugated pipe, one end of the corrugated pipe penetrates through the clamping sleeve and the seal washer and then extends into the connection hole of the joint, one end of the locking screw is screwed with the outer side of the joint, and the other end of the locking screw is limited on the outer circumferential surface of the clamping sleeve through a limit structure; the inner wall of the connection hole is provided with a step 1, the inner end of the seal washer is provided witha tilt surface which can extend into the connection hole and support against on the step1, and the outer circumferential surface of the seal washer is provided with an annular groove. The quick jointof the corrugated pipe for gas has the advantages of favorable seal performance and quick installation.

Description

technical field [0001] The invention belongs to the technical field of gas, and relates to a quick joint, in particular to a quick joint of a corrugated pipe for gas. Background technique [0002] In daily life, gas has become an indispensable part of people's life. In the process of using gas, it is often necessary to connect and disassemble the gas pipes. In order to realize fast operation and ensure its tightness (because gas leakage will cause very serious consequences), people have designed various quick connectors for gas, and some have applied for patents. [0003] For example, the Chinese patent literature discloses a high-temperature-resistant metal bellows quick connector for gas [Patent No.: ZL200620107454.X], which includes a nut and a joint screwed on the inner wall of the nut. The ring is provided with a clamping ring and a pressure ring protruding inward. The clamping ring is located at the right end of the clamping ring, and the pressure ring is located at ...
