An anti-loose connection pipeline fastener

Abstract

The invention belongs to the technical field of pipeline transportation, and specifically relates to an anti-loosening connection pipeline fastener, which includes a pipeline, a rotating lock housing and a sealing ring; the outer surface of the pipeline is abutted against a fixed lock housing; the fixed lock housing The lower end surface of the rotating lock housing is hinged with a rotating lock housing; a sealing strip is provided on one side of the rotating lock housing relative to the fixed lock housing; There is a sealing ring; through the present invention, the rapid sealing of pipeline leakage is effectively realized. Through the snap-fit ​​structure, it is convenient for temporary treatment of different pipeline leakage. Fixing, reducing the looseness of the pipeline, can effectively avoid the occurrence of detachment accidents between the pipelines. Compared with the traditional blocking measures, the fixing equipment has strong adaptability, better fixing effect, and is easy to use and easy to disassemble quickly.

Description

technical field [0001] The invention belongs to the technical field of pipeline transportation, in particular to a fastening piece for anti-loose connection pipelines. Background technique [0002] A pipeline is a device used to transport gas, liquid or fluid with solid particles connected by pipes, pipe connectors and valves; usually after the fluid is pressurized by a blower, compressor, pump and boiler, it is discharged from the high pressure of the pipeline Flowing to the low pressure place, it can also be transported by the pressure or gravity of the fluid itself. Ordinary steel pipes have threaded connection, flange connection, welding connection, socket connection, pipe bonding connection and other methods; due to the pressure difference of the pipeline, the fluid passes through the pipeline. Internal flow for fluid delivery. [0003] According to CN104373706A, a composite delivery high-pressure oil pipe, by using a three-layer structure, avoids the harm caused by in...

Problems solved by technology

[0006] In order to make up for the deficiencies of the existing technology and solve the problem in the prior art, the greater the pressure difference inside the pipeline, the more efficient the fluid delivery can be achieved under the same other conditions, but the greater the pressure difference inside the pipeline, the greater the pressure of the fluid on the pipeline. The strength and sealing requirements of different pipe joints are also higher, especially for inset pipe connections, adhesive connections, threaded connections or flange connections. Pipes through these connection methods are very easy to loosen under high pressure for a long time , or even a separation accident between two pipelines. For ordinary low-pressure pipelines, when there is a water leakage problem, temporary sealing can be carried out by tape, welding or blocking blocks, etc., but the effect of this blocking measure is poor, and it is easy to cause detachment Or a large number of leakage problems, but these sealing methods cannot effectively solve the problems of loosening between pipes or separation between pipes, especially when water leakage occurs in high-pressure pipes, the above measures are difficult to implement, and cannot effectively resist high pressure In order to solve the problems of external water spray and other problems, the present invention proposes a kind of anti-loose connection pipeline fastener
