Abstract

The invention discloses a high-pressure gas joint leak-protection structure. The high-pressure gas joint leak-protection structure comprises a joint body and a joint component, wherein one end of the joint component is connected with the joint body, and the joint component is used for tightly pressing a nut. A protective cover is arranged outside the joint component. One end of the protective cover is an open end, and the other end of the protective cover is a sealed end. An internal thread is arranged on the portion, close to the open end, of the protective cover. An external thread is arranged on the periphery of the middle portion of the joint body. The middle portion of the joint body is connected with the protective cover in a threaded mode. A protective cover through hole is formed in the sealed end of the protective cover. A one-way valve is further arranged on the protective cover. According to the high-pressure gas joint leak-protection structure provided by the invention, a leak portion is designed on the high-pressure gas joint leak-protection structure and located on the periphery of a component to which gas is supplied, the original structure of the component to which gas is supplied is not changed, the structure is compact, and requirements of small natural gas engines are met.

Description

technical field [0001] The invention belongs to the technical field of gas engine components, and in particular relates to a leakage protection structure for a high-pressure gas joint. Background technique [0002] In the prior art, in order to avoid gas leakage during the high-pressure gas transmission process of marine natural gas engines, it is necessary to design leakage places on the parts to be supplied with gas, and to use gas detection and removal devices, so the anti-leakage structure is very large in size. This anti-leakage structure can still be used on large engines, but the volume of small high-speed engines is relatively small, which is far from enough to provide the space required by the anti-leakage structure of the prior art. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a leakage protection structure for high-pressure gas joints, where the leakage location is designed on the leakage protectio...
