ESD emergency shut-off valve

Gas liquid linkageball valveWidely used in long-distance transportation of purified natural gas, coal gas and other pipelines, as an opening and closing device or emergency rescue device for pipeline rupture (with emergency cut-off system for pipeline rupture). thatvalveIt is a self reliant approachball valveWithout the need for external energy, it can be driven by the pressure of the pipeline's own mediumvalveAction, implementation of development or closure. KaitamvalveGas and liquid linkage produced by China Limited Companyball valveIt is divided into two categories: emergency rescue devices without pipeline rupture and emergency rescue devices with pipeline rupture.

1. Without an emergency rescue device for pipeline rupture, this typevalveDriven by the pressure of the pipeline's own mediumvalveWhen there is no pressure in the pipeline, the hydraulic oil in the gas-liquid tank can be manually pumped into the driver cylinder through an oil pump to achievevalveAction, or additional energy storage tank (optional), using the gas in the energy storage tank asvalveThe driving force behind the action. If the user needs it, remote control can also be implemented (optional).
2. Equipped with emergency rescue devices for pipeline rupturevalveWithout an emergency rescue device for pipeline ruptureball valveSimilarly, relying on managing one's own pressurevalveThe power source. When there is no pressure in the pipeline, the gas pressure in the manual oil pump or energy storage tank can be used asvalveThe driving force behind the action. When the downstream pipeline ruptures, the pressure in the pipeline is bound to decrease. When the rate of pressure decrease reaches the set value of the system,valveAutomatically close to prevent a large amount of medium from flowing out.
