Description

Technical Field

[0001] The utility model relates to the technical field of gas pipeline monitoring, in particular to a gas pipeline pressure detection device. Background Art

[0002] Gas pipelines refer to pipelines mainly used to transport natural gas, liquefied petroleum gas, and manufactured coal gas. In long-distance transportation, gas pipelines specifically refer to the transportation of natural gas media. In towns, gas pipelines refer to the transportation of natural gas, liquefied petroleum gas, manufactured coal gas and other media. They are widely used. During their laying process, pressure detection equipment is usually installed to perform real-time detection of the pressure inside the pipe body.

[0003] The existing gas pipeline pressure detection device has the following disadvantages when in use: the pressure gauge is the most commonly used pressure detection equipment, which is usually installed directly on the periphery of the gas pipe. Although the pressure gauge itself has the characteristics of waterproofness and high strength, when used for a long time in some special environments, especially in humid and corrosive environments, the pressure gauge shell structure and its installation end are prone to aging, rust and other problems. For this reason, we propose a gas pipeline pressure detection device. Utility Model Content

The inside of the annular groove is movably connected with an insert tube through a spring B. The mounting tube at the bottom of the pressure gauge is used to dock with the installation position of the gas pipe. When docking, the insert tube is lifted up so that its top is inserted into the annular groove, the spring B is compressed, and the mounting tube is exposed to facilitate docking with the docking tube. After the pressure gauge is installed, the insert tube is released, and the spring B pushes it downward so that its bottom fits the top of the docking tube. Through the cooperation of the sleeve and the insert tube, the mounting end of the pressure gauge is isolated and protected.

[0008] Furthermore, a groove is provided on one side of the baffle surface for conveniently controlling the opening and closing of the baffle, and a rubber pad is bonded to the bottom of the baffle; the groove structure facilitates the movement of the baffle to control its opening and closing, and the rubber pad structure can improve the bottom sealing when the baffle is closed.
