Hydraulic automatic bursting pipe shut-off valve

水力自动爆管关断阀is generally installed near important areas that require protection on water pipelines without power supply along the way. When the pipeline is in normal condition, the burst shut-off valve is open. In the event of a burst accident, the burst shut-off valve senses changes in flow velocity and can automatically close, cutting off the pipeline and preventing huge disasters caused by the burst.

feature
Reduce water loss caused by bursting pipes and avoid secondary disasters. When the water supply pipeline bursts, the burst shut-off valve automatically closes, quickly cutting off the water flow and effectively preventing or reducing the loss of burst pipes.
No external power source is required. The closing torque of the valve is the torque of the heavy hammer. The closing drive of the burst pipe shut-off valve does not require external power. As long as a burst pipe accident occurs, the valve will quickly and automatically close urgently.
The closing speed is adjustable. It can effectively prevent water hammer caused by closing the valve too quickly.
There are multiple options for the main valve. Eccentric hemispherical valves and butterfly valves can both be used as main valves.
