The lower end of described movable dead bolt is ramp structure, and can only move up and down along described dead bolt tubular slideway.
Described upper water through hole is mutually vertical with backwater through hole.
Described control rotating shaft and be provided with rubber water shutoff pad between described water supply pipeline and water return pipeline.
The utility model compared with prior art has the following advantages:.
1, owing to being provided with described water return pipeline in the utility model, therefore, after water tank can be made to fill water, the water of spilling flows back to water source place through return pipe, is convenient to collect use, and reduces the waste of water.
2, because water through hole upper in the utility model is mutually vertical with backwater through hole, therefore, when water inlet can be made to open water, after water tank fills water, return pipe lower end is closed, and the water of spilling directly flows out without return pipe lower end, thus enters exhaust chamber and piston chamber; And the water overflowed is when flowing out through return pipe lower end, water inlet is closed and is no longer continued to go up water, effectively realizes automatic shutoff.
3, owing to being provided with water return pipeline, exhaust chamber, piston chamber in the utility model, the lower end of described exhaust chamber is communicated with described water return pipeline, and upper end is provided with exhaust port, and its inside is provided with float, and described float upper end is provided with soft rubber film; The lower end of described piston chamber is communicated with described water return pipeline, and its inside is provided with piston, and the upper end of described piston is connected with described movable dead bolt, and therefore, after water tank can be made to fill water, the water of spilling cannot not flow back to return pipe because return pipe lower end closes; Along with the discharge of backwater inner air tube, when the water of spilling enters exhaust chamber, float is floated, effective blocking exhaust port, makes the water in return pipe can not flow out through exhaust port, thus produces effective pressure to piston, and then promotion activity dead bolt moves, start automatic device for cutting-off water.
4, because the upper end of dead bolt movable described in the utility model is provided with Compress Spring, lower end is ramp structure, therefore, on need during water, positioning work piece can be made to slip over the sublingual end of active lock, be effectively locked again afterwards.
5, be provided with positioning work piece and torsion spring owing to controlling rotating shaft described in the utility model, in described casing, be provided with stop block, therefore, on need during water, control rotating shaft can be effectively locked, open water through hole, close backwater through hole; After water tank fills water, control rotating shaft and reset in time, close and close water through hole, open backwater through hole, effectively realize automatic shutoff.
6, owing to controlling rotating shaft described in the utility model and being provided with rubber water shutoff pad between described water supply pipeline and water return pipeline, therefore, can water leakage phenomenon be prevented, effectively improve the performance of this automatic water cut-off device.
6, the utility model structure is simple, easy to operate, makes, safeguards, user cost is lower, be especially applicable to the automatic shutoff of elevated tank and closed tank.
