Abstract

The invention relates to a socket, a plug and a connecting device for a gas pipeline, and belongs to the technical field of gas pipeline connection. The socket comprises a conversion seat and a valveseat; an air inlet interface and an air outlet interface which are in communication with each other are formed in the conversion seat; the air outlet interface is fixedly connected to the valve seat,and a valve core is arranged in the valve seat in a sealing mode; a gas channel communicating with the valve seat is formed in the valve core, and the gas channel is in communication with or closed with air inlet interface by the axial movement of the valve core; one end, away from the air outlet interface, of the valve core is provided with a first sealing ring; an unlocking ring for blocking thefirst sealing ring from sliding out is arranged in the valve seat; and a locking assembly is connected to the valve seat. The socket, the plug and the connecting device have the beneficial effects that when a user installs the socket, the plug and the connecting device, only the plug needs to be inserted into the valve seat, the locking assembly is used for locking the plug, then the installationcan be completed, the installation is simple and convenient, and the installation efficiency is remarkably improved; and during dismounting, only the plug needs to be unlocked and pulled out, the valve core can be automatically closed, operation is very convenient, and popularization and application are facilitated.

Description

technical field [0001] The invention relates to the technical field of gas pipeline connection, in particular to a socket, a plug and a connection device for a gas pipeline. Background technique [0002] Existing indoor gas pipelines are divided into two forms: open installation and concealed installation, and there are conversions between fixed pipelines and movable pipelines for gas appliances. For surface installation, a valve with a conversion joint or a special conversion joint is installed on the pipeline to realize the connection between the fixed pipeline and the hose of the gas appliance. For concealed installation, stainless steel corrugated pipes or aluminum-plastic composite pipes are buried in the wall, then the pipes are bent and protruded directly from the wall, and then valves and conversion joints are installed at the pipe ends to realize the connection between fixed pipes and gas appliance hoses . When installing the valve and switching, it is necessary t...
