Pressure relieving pipeline

Abstract

The invention discloses a pressure relieving pipeline which comprises a pipeline body, wherein a first connecting pipe is fixedly connected to the side wall of the pipeline body; the first connectingpipe communicates to the inner cavity of the pipeline body; a first fixed block is fixedly connected to the side wall of the first connecting pipe; a second connecting pipe is arranged on the upper side of the first connecting pipe; a second fixed block is fixedly connected to the side wall at the lower end of the second connecting pipe; the second fixed block leans against the first fixed block;the second fixed block and the first fixed block are fixedly connected through a bolt; two sliding chutes are symmetrically formed in the inner wall of the second fixed block; slide blocks are slidably connected in the two sliding chutes; and a baffle plate is fixedly and jointly connected to the two slide blocks. The pressure relieving pipeline disclosed by the invention is simple and reasonablein structure, and can unload effectively to reduce the dynamic load acted to the inner wall of the pipe, so that the service life of the pipeline is prolonged favorably. Meanwhile, the pressure relieving pipeline is provided with an alarm device, so that the alarm device can raise the alarm when the change of pressure is relatively great.

Description

technical field [0001] The invention relates to the technical field of pipelines, in particular to a pressure relief pipeline. 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 blowers, compressors, pumps and boilers, it flows from the high-pressure part of the pipeline to the low-pressure part, and it can also be transported by the pressure or gravity of the fluid itself. Pipes are widely used, mainly in water supply, drainage, heat supply, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial devices. The existing pipeline itself does not have a pressure relief device, because the pressure in the pipeline is very unstable, and the repeated action of variable load on the pipe wall is prone to fatigue failure, which greatly reduces the service...

Problems solved by technology

The existing pipeline itself does not have a pressure relief device. Because the pressure in the pipeline is very unstable, the repeated action of variable load on the pipe wall is prone to fatigue failure, which greatly reduces the service life of the pipeline.
