Abstract
The utility model relates to a piston type water saving valve. The inner cavity of the valve body of the utility model is connected with a projection which has the action of guide on a piston core which is arranged between a water inlet and a water outlet. The inner cavity of the piston core is provided with an eccentric wheel, and the piston core moves up and down through the convex and concave of the eccentric wheel for achieving the function of opening or closing tap water. The utility model has the advantages of simple structure, convenient operation, and long service life.
Description
The utility model belongs to valve type, relates in particular to a kind of piston-type underwater valve.
At present, the water valve that people use, what generally adopt is Ball valve, its ball valve core and handle are fixed together, and are provided with the sealed nylon pad between ball valve core and valve body, by rotatable handle, regulate the position of ball valve core.Finish the open and close of current.This valve uses soon, and the sealed nylon pad is just easily aging, causes Ball valve to be not closed completely, and during operating cost, changes difficulty, brings inconvenience to the user.
The purpose of this utility model is to provide a kind of easy and simple to handle, water-outlet quantity is big, valve can be closed current after out of control automatically piston type water-saving valve.
The utility model is achieved in that the water-saving valve of being made up of valve body, piston core, stage clip and seal rubber pad, its valve body internal organ have the projection that is connected as a single entity with it, it is to the generation leading role that moves up and down of piston core, the center of piston core has a groove, be combined with eccentric wheel in the groove, the end that eccentric wheel stretches out outside the valve body is provided with handle, the seal rubber pad that between the bottom of piston core and water outlet, is equipped with, and it is tightly withheld in valve body.
The utlity model has simple in structurely, time saving and energy saving, the characteristics that water consumption is few owing to adopted eccentric structure, have increased the frictional contact surface of piston core and eccentric wheel work, and improved 3-5 times than ball valve working life.
Accompanying drawing is a structural representation of the present utility model.
Now in conjunction with the accompanying drawings embodiment of the present utility model is described further:
Valve body 1 has water intake 5, water outlet 9 and projection 7 are formed, its water outlet 9 is greater than water intake, stage clip 2 is housed in valve body 1, piston core 3 and seal rubber pad 8, its projection 7 is connected as a single entity with valve body 1, cooperate with piston core 3, play the guiding role when piston core 3 is moved up and down in valve body 1, have a rectangular slot in the middle of the inner chamber of piston core 3, eccentric wheel 6 is contained in this chamber, eccentric wheel 6 can be unidirectional also can be two-way, the end that eccentric wheel 6 stretches out outside the valve body 1 is provided with handle 4, connects with locating stud, between the bottom of piston core 3 and water outlet 9, a seal rubber pad 8 is housed, tightly is buckled in the lower end of valve body 1.During work, handle with sleeve 4 one angles make eccentric wheel 6 projectioies, promotion piston core 3 produces the top power that makes progress and leaves bottom compression press spring 2, water flows out from water outlet 9 along valve body 1 inboard seal rubber pad 8 endoporus that pass through, when closing, and handle with sleeve 4, make eccentric wheel 6 convex portions leave piston core 3, piston core 3 moves rapidly downwards under the effect of stage clip 2 and tap water at this moment, and the bottom compresses seal rubber pad 8, blocked the outlet of water outlet 8, played and dammed and seal action.
