Description

A water inlet valve height adjustment mechanism

technical field

The utility model relates to the technical field of water inlet valves, in particular to a water inlet valve height adjustment mechanism.

Background technique

In the prior art, the water inlet valve usually includes a water inlet pipe, a main body of the water inlet valve, a control valve, a control rod, a buoy bucket and a buoy box. , the water inlet pipe is socketed in the main body of the water inlet valve, and a control valve is set in the main body of the water inlet valve to control the flow of water through the control valve, and the closing of the control valve is realized by the action of the control rod; In the floating tank, the floating tank is installed on the main body of the water inlet valve.

When the water level of the floating tank drops, the floating bucket is lowered by gravity, and the control rod is driven to open the control valve. When the water level of the buoyancy tank rises, the buoyancy of the buoyancy increases the buoyancy of the buoyant bucket, which drives the control rod to close the control valve and stop the water intake.

When the water inlet valve is installed in the flush water tank, the installation height of the water inlet valve needs to be adjusted due to the different models of the flush water tanks.
