Abstract
The utility model provides a vacuum and drop-proof water saving valve, belonging to the technical field of valve, which is essentially characterized in that the valve top is provided with a handle and also a water inlet and a water outlet; wherein, the lower end of the handle is provided with a screw rod that is connected with a nut, and the nut is fixed with a piston, with a lower end having a spring that is further provided with a piston. Compared with the prior art, the utility model has advantages of simple structure and convenient operation as well as saving water resource and preventing water sealing.
Description
The utility model belongs to valve technology field, relates to a kind of vacuum lock and drips water-saving valve.
At present the water valve that uses is not closed completely, and can seep water, drips, waste water resource.
The purpose of this utility model is the water-saving valve that a kind of Shi Buhui of closing of design drips.
The technological scheme that the utility model is taked is to have valve body, and the valve body top is provided with handle, also is provided with water intake, water outlet, and handle, at its lower end is connected with screw mandrel, screw mandrel links to each other with screw, be installed with piston on the screw, the screw lower end is provided with spring, and the spring lower end is provided with piston again.
Because the utility model taked technique scheme, compared with prior art, has the advantage of simple in structure, easy to use, conserve water resource, prevention stolen water.
Below in conjunction with accompanying drawing and example, structure characteristic of the present utility model is described further.
Fig. 1 is a general assembly structural representation of the present utility model.
Referring to Fig. 1, the utlity model has valve body 1, valve body is provided with handle 2, water intake 3, water outlet 4, and handle 2 lower ends are connected with screw mandrel 5, and screw mandrel 5 links to each other with screw 6, is installed with piston 7 on the screw 6, and screw 6 lower ends are provided with spring 8, and spring 8 lower ends are provided with piston 9 again; Piston 7 is opened earlier, move when being no less than 0.3cm, piston 9, spring 8 move up and are no less than 0.3cm, this moment, piston 9 still was in closed condition, when screw mandrel 5 upwards moves 0.25cm again, piston 7,9 is opened, and reach the water supply purpose this moment, and closing this block of valve, to close order be front and back open and close order with opening ways; Rotatable handle 2 makes upwards jack-up of screw mandrel 5, and piston 7 is away from packing ring 10, and spring 8 is being with piston 9, and away from water intake packing ring 11, like this, water enters from water intake 3, piston 9, and piston 7 is opened, and water has just come out from water outlet 4.
