Description

Technical Field

[0001] The utility model relates to the field of gas pipe joints, in particular to a gas pipe joint. Background Art

[0002] As urban and rural pipeline gas, natural gas, liquefied petroleum gas, biogas and other gases enter thousands of households, they have brought people clean fuels that are easy to use, hygienic and pollution-free. These gases are mainly connected between combustion appliances through two types of gas interfaces. One is the pagoda joint that is widely used in liquefied gas cylinders in accordance with international standards. Since the pagoda joint is generally annular corrugated, there is a large gap between the rings and has corrugations, it can effectively prevent the gas pipe from falling off after connecting the hose. The other is the British 1 / 2" threaded interface.

[0003] When the existing gas pipe joint is in use, there may be a gap after the pipes are connected, so there will be gas leakage. Since the delivery pipeline is long, the gas leakage cannot be detected, which not only wastes resources but also pollutes the environment. The metal bellows only contacts the sealing plug, and the sealing rubber ring is sealed on the covering part. The metal bellows has no other connection relationship with the external joint. The connection is not firm enough, and there is a safety hazard of loosening. In addition, the sealing is still not ideal, which brings certain adverse effects to people's use process. For this reason, we propose a gas pipe joint. Utility Model Content
