The utility model, when preventing to cut off the water, tank water backflow pollution water system can be provided with flap valve on described exhalant canal.Flap valve comprise tubular check valve body 15, place " ten " shape support 17 in the tube, be arranged at support the inner gasket seal 16, can with the external activity pipe of support just in the locking plate on the check valve body 15 18 and place support 17 and locking plate 18 between spring 19, the inner of check valve body is provided with external screw thread and can be connected with the exhalant canal 22 of valve body 1, the outer end of check valve body is provided with internal thread, can match with locking plate 18, locking plate 18 is provided with water hole.

The utility model is used when being installed on water closet, its operating principle is: when drawdown pneumatic cup 9 loss of buoyance, the acting in conjunction of the gravity of pneumatic cup and water inlet spring 12, water level control lever 7 descends, make sealing ring 10 break away from sealing cap top through hole 24, at this moment, the pressure of the cavity B that is made of sealing cap 3 and switch elastomeric pad 4 equates that with atmosphere promptly the pressure in the cavity B is less than the pressure of hydraulic pressure, under the effect of hydraulic pressure, switch elastomeric pad 4 is lifted, thereby opened the passage of intake tunnel 21 and exhalant canal 22, to the water tank water-filling, the water inlet direction is " A ", be that switch is in opening state, simultaneously, a small amount of tap water slowly enters cavity B by water inlet groove 64, releases from the through hole 24 on sealing cap top, the sluicing direction is " B ", shown in Fig. 2 B.When the water level in the pond rises to pneumatic cup and goes to the bottom, air in the pneumatic cup forms a buoyancy, continuous rising along with water level, buoyancy is increasing, when floatage energy overcomes the weight of the tension force of spring and pneumatic cup 9 and screw rod 8, water level control lever 7 is pulled up, seal the through hole 24 of sealing cap 3 upper surfaces until sealing ring 10, because the effect of the screen resilience of switch elastomeric pad 4, tap water slowly enters cavity B by water inlet groove 64, equates with the hydraulic pressure of tap water until the pressure of cavity B, owing to the pressure of exhalant canal equates with atmospheric pressure, therefore the pressure in the cavity B is greater than atmospheric pressure, switch elastomeric pad 4 is closely attached on the inlet of exhalant canal, has promptly closed exhalant canal 22, stops to the water tank water-filling, be that valve is in closed condition, shown in Fig. 2 A.

The operating principle of flap valve is: when tank intake valve of water is in " open-minded " state, the hydraulic pressure of tap water is during greater than the pressure of spring 19, and gasket seal 16 is opened, and to the pond water-filling, generally speaking, the water in pond is full; After finishing to the pond water-filling, tank intake valve of water is in " closing " state, and under the effect of spring 19, gasket seal 16 is sealed the exhalant canal 22 of tank intake valve of water, and when running water system was cut off the water, the water in the pond can not flow backwards yet, and can not pollute water system.
