Abstract

The invention discloses a rapid detection device for a natural gas pipeline, which comprises a plug column; a small base ring is arranged on the plug column, a small air-filled sealing ring is arranged on the small base ring, and an air-filled cylinder block and an air-released cylinder block are arranged in a column groove; an air-filled piston is arranged in the air-filled cylinder block, a first piston rod is arranged on the air-filled piston, a pressing plate is arranged on the first piston rod, and a first spring is arranged in an inflating cavity. An air-released piston is arranged in the air-released cylinder block, a second piston rod is arranged on the air-released piston, and a stay cable is arranged on the second piston rod. The invention also comprises a sleeve and a push post,wherein the sleeve is provided with a large base ring; a large air-filled seal ring is arranged on the large base ring; one end of the stay cable is connected with the second piston rod, and the other end of the stay cable is provided with a counterweight block. The device has the advantages that the structure is reasonable, the operation is relatively simple in use, the sealing property test canbe effectively carried out on the welded part of the PE natural gas pipe and the corner electric fused sleeve, the sealing property of the welded part can be accurately measured, and the safety in subsequent use can be ensured.

Description

technical field [0001] The invention belongs to the technical field of natural gas pipelines, in particular to a quick detection device for natural gas pipelines. Background technique [0002] PE natural gas pipeline (PE natural gas pipeline) has been widely used in the field of natural gas transportation. PE natural gas pipelines mainly include PE natural gas pipes, electrofusion casings, PE valves and other structures. A PE valve for docking or for some other form of docking. Among them, the electrofusion casing can be divided into straight-through electrofusion casing and corner electrofusion casing. [0003] The corner electrofusion casing belongs to the existing technology in the field of PE pipe valves, which includes a PE pipe body (the PE body pipe of the corner electrofusion casing includes two straight pipe sections perpendicular to each other and a middle elbow section, and the middle elbow section is used for For connecting two straight pipe sections) and the ...
