Universal fixture for fluid pipeline belt pressure leaking stoppage

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 universal clamp for fluid pipeline plugging under pressure. Background technique [0002] The fluid pipe is a steel pipe with a hollow cross-section and no welds from the beginning to the end. The steel pipe has a hollow cross-section and is used in large quantities as a pipe for transporting fluids to transport oil, natural gas, gas, water and certain solid materials. Steel pipes and Compared with solid steel such as round steel, the weight is lighter when the bending and torsional strength is the same. It is an economical section steel and is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile transmission shafts, bicycle frames and The steel scaffolding used in building construction, etc., the fluid pipelines that run all the year round will leak due to various reasons, but the existing fluid pipeline pressure ...
