Abstract

The invention relates to the technical field of connection equipment for ultra-high pressure gas pipelines, in particular to a quick-plug connector for ultra-high pressure gas pipelines with a protection device and an operating method thereof. The ultra-high pressure gas pipeline push-in joint with protection device includes a fixed end assembly, a movable end assembly and a protection card arm. The anchor points form a fixed fit relationship; the push-in joint also includes a limit component for limiting the maximum axial displacement action distance of the protection card arm. The invention can not only realize the function of online plugging and unplugging under pressure by hand, but also have extremely high use safety and operation reliability, so that it is suitable for use in ultra-high pressure gas pipelines. Another object of the present invention is to provide an operation method based on the above-mentioned ultra-high voltage push-in connector, so as to realize the purpose of free-hand plugging under pressure more conveniently and safely, including the docking step and the separation step.

Description

technical field

[0001] The invention relates to the technical field of connection equipment for ultra-high pressure gas pipelines, in particular to a quick-plug connector for ultra-high pressure gas pipelines with a protection device and an operating method thereof. Background technique

[0002] Ultra-high pressure push-in connectors are widely used in the connection of ultra-high pressure gas pipelines. When connecting the pipelines, the connection or disconnection of the pipelines can be realized without the use of other tools. Its working pressure exceeds 70MPa. It is an ultra-high pressure pipeline system An important part of the connection that has a major impact on the safety and reliability of the system. Due to the lack of relevant national standards, the push-in joints used in the existing ultra-high pressure pipeline system are mainly improved on the basis of the 40MPa high-pressure pipe joint standard. In addition to the problems of complex processing and manufact...
