A universal fixture for plugging fluid pipelines under pressure

Abstract

The invention discloses a universal fixture for fluid pipeline belt pressure leaking stoppage and relates to the technical field of fluid pipelines. The universal fixture for the fluid pipeline belt pressure leaking stoppage comprises an upper clamping collar and a lower clamping collar; sleeves distributed in a circumferential array are fixedly installed on the outer surface of the upper clampingcollar; sleeves distributed in a circumferential array are fixedly installed on the outer surface of the lower clamping collar; a pressure detection meter is fixedly inserted into the right side of the upper clamping collar; the interiors of the sleeves are in threaded insertion with adjusting screw rods; rotary knobs are fixedly installed at the top ends of the adjusting screw rods; and antiskidgrooves laid uniformly are formed in each of the upper side and the lower sider of the front of the upper clamping collar. The universal fixture for the fluid pipeline belt pressure leaking stoppageis high in tensile strength and good in structural stability; enough and lasting radial pressure can be exerted after the clamping collars are tightly hooped so as to allow the fixture to be compressed on the excircle surface of a pipeline, so that the sealability is improved, the leaking stoppage effect is improved, and the potential safety hazard is eliminated; and pressure on the inner side ofthe fixture can be detected in real time, so that a user conveniently judges whether the problem of oil leakage or gas leakage happens according to the pressure on the inner side, and disconnecting detection is avoided.

Description

Technical field [0001] The invention relates to the technical field of fluid pipelines, in particular to a general clamp for fluid pipelines to plug leaks under pressure. Background technique [0002] The fluid pipe is a kind of steel pipe with a hollow section from beginning to end without welds. The steel pipe has a hollow section. It is used as a pipe for transporting oil, natural gas, gas, water and certain solid materials. Compared with solid steel such as round steel, it is lighter when the bending and torsion strength is the same. It is a kind of economical cross-section steel, which is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile transmission shafts, bicycle frames and Steel scaffolding used in construction, fluid pipelines that have been in operation all year round may leak due to various reasons, but the existing fluid pipelines with pressure plugging fixtures have poor plugging performance, poor sealing pe...
