A plugging device for a pressure pipeline

Abstract

The invention discloses a plugging device for pressure pipelines. The plugging device for the pressure pipelines comprises an installation disc, a fixed frame, a high-pressure pipe, a connection pipe,a fixing block, an air-inflation barrel, an air-inflation valve, an air-suction valve, an air bag and a water drainage port, wherein the fixed frame is fixedly connected to the outer side of the installation disc; the high-pressure pipe is connected to the left end of the installation disc in a clamping manner; the connection pipe is fixedly connected into the installation disc; the fixing blockis fixedly connected into the connection pipe; the air-inflation barrel is fixedly connected into the fixing block; the air-inflation valve is fixedly connected into the air-inflation barrel; the air-suction valve is fixedly connected into the upper end of the air-inflation barrel in a sleeved manner; the air bag is connected to the left end of the air-inflation barrel through a thread; the waterdrainage port is formed in the installation disc; and the installation disc is made from a stainless steel material. The invention relates to a plugging device for pressure pipelines. The plugging device for the pressure pipelines has the characteristics of being capable of rapidly connecting pipelines with many types and plugging the pipelines in the pipelines.

Description

technical field [0001] The invention belongs to the technical field of pressure pipelines, in particular to a sealing device for pressure pipelines. Background technique [0002] In a broad sense, pressure pipes refer to all pipes subject to internal or external pressure, regardless of the medium in the pipe. The pressure pipeline is a part of the pipeline. The pipeline is used to convey, distribute, mix, separate, discharge, measure, control and stop fluid flow. It consists of pipes, fittings, flanges, bolted connections, gaskets, valves, and other components. Or the assembly assembly composed of pressure parts and support parts, when repairing the pressure pipeline, it is necessary to use the sealing device to block the pipe opening, but there are some problems in the current sealing device: 1. The connection method is mostly bolt connection , The connection process is too cumbersome, and the type of the connecting pipeline is too single; 2. The pipeline is only blocked a...

The pressure pipeline is a part of the pipeline. The pipeline is used to convey, distribute, mix, separate, discharge, measure, control and stop fluid flow. It consists of pipes, fittings, flanges, bolted connections, gaskets, valves, and other components. Or the assembly assembly composed of pressure parts and support parts, when repairing the pressure pipeline, it is necessary to use the sealing device to block the pipe opening, but there are some problems in the current sealing device: 1. The connection method is mostly bolt connection , the connection process is too cumbersome, and the model of the connecting pipeline is too single; 2. Only seal the pipeline at the mouth of the pipeline, which will easily cause leakage after sealing, and it is not easy to remove
