Problems solved by technology
[0002] In the pipeline system, pipeline rupture and valve damage often occur, so it is necessary to replace the ruptured pipeline or valve, which not only has long working hours and high cost, but also has adverse effects on life and production
The industry has proposed a quick way to maintain pipelines. This method is usually to set a special valve to cut off the fluid on the pipeline upstream and downstream of the rupture or upstream of the damaged valve to reduce leakage. However, this method needs to be installed in a dedicated The upstream and downstream pipelines at the rupture of the pipeline in the valve valve body or the upstream pipeline of the damaged valve cut a cut for placing the rubber gate; how to realize this function, there is no special tool to realize it at present

Description
technical field [0001] The invention belongs to the field of pump valves, and in particular relates to a special tool for quick maintenance of pipelines. Background technique [0002] In the pipeline system, pipeline rupture and valve damage often occur. Therefore, it is necessary to replace the ruptured pipeline or valve. This not only takes a long time and costs a lot, but also brings adverse effects on life and production. The industry has proposed a quick way to maintain pipelines. This method is usually to set a special valve to cut off the fluid on the pipeline upstream and downstream of the rupture or upstream of the damaged valve to reduce leakage. However, this method needs to be installed in a dedicated The upstream and downstream pipelines at the rupture of the pipeline in the valve valve body or the upstream pipeline of the damaged valve cut a slit for placing the rubber gate; how to realize this function, there is currently no special tool to realize it.
