The metal braided hose should avoid water hammer, and the technology of slow opening, quick closing, slow closing, etc. to remove water hammer, to avoid the harm of open pipelines and pump stop reverse flow and water hammer to water supply pipelines and centrifugal pumps. The sealing structure of the metal braided hose should be a structure with ductility and torque force, and the upper, middle and downstream sealing seats are additionally sealed. The metal braided hose and the seal are always sealed. The actual operation is convenient, and there is no need to install another electronic control system for the metal braided hose. The metal braided hose is automatically and sequentially operated with the opening and termination of the pipeline.

Adjust the valve opening according to the setting to obtain suitable main parameters. When the pipeline is drained from the leaking end, the metal braided hose enters the control room, and the outlet pressure is applied to the pipeline according to the function of the hose. When the outlet pressure is higher than the preset value of the pipeline, the pipeline is turned off, and the control room terminates the drainage pipeline. At this time, the main valve controls the indoor pressure to rise and turns off the metal braided hose, and the outlet pressure does not rise. When the outlet pressure drops to the set pressure of the pipeline, the pipeline is opened, and the control chamber drains the pipeline to the middle and lower reaches. Because the outflow of the pipeline exceeds the inflow of the needle control valve, the pressure in the control chamber of the main valve decreases, and the inlet pressure causes the main valve to open.
