What if the water valve freezes?

Best answer: External heating method: use steam, hot water, fire roasting, electric heating and other means to melt the frozen ice in the water valve into water and discharge it to achieve dredging effect; In-pipe heating method: the pipe is removed, and steam, water, salt water, etc. are introduced into the pipe with a hose thinner than the pipe to melt the ice in the water valve and dredge the water valve. Outside-pipe heating method can be used for thinner pipes, and inside-pipe heating method can be used for thicker pipes.

water valve:

In the water flow system of hydraulic turbine, according to the needs of operation and maintenance of hydropower station, corresponding gates or valves are installed at different positions, and the valve installed in front of the volute of hydraulic turbine is usually called inlet valve.

Generally, the inlet valve of micro-unit is operated manually. The inlet valve of small-sized units generally adopts electric operation mode. On the electric operation mechanism, there is also a manual operation mechanism to ensure the reliable operation of the inlet valve. The water inlet valve is opened and closed by a motor or a manual operating handle through a speed change mechanism (i.e., a reduction box), a screw, a nut and a rotating arm.

For large-diameter inlet valves that require a great operating torque, hydraulic operation is adopted to ensure the closing speed of the inlet valves.
