Abstract
The utility model discloses a novel water-saving tap, which is composed of a rotating handle, a valve rod, a valve core, a valve seat, etc. The valve rod (2) is installed in an upper body (5), and the valve rod (2) or the inner wall of the upper body (5) is provided with moment changing threads (3) in a carved way; a cylindrical guide pin (4) is fixed on the side wall of the upper wall (5) or inside the valve rod (2); one end of the guide pin (4) is inserted in the groove of the moment changing threads (3). The valve seat (6) is fixed in a valve body (8), and the center of the valve seat is provided with a valve port; the valve core (7) is arranged in the valve seat (6) and is positioned below the valve port, and the valve core (7) and the valve port are in the same center line; the bottom of the valve core (7) is provided with a spring (9) which can prevent the valve core (7) from falling down when the water supply is cut off, and the closing state can be ensured. The utility model has the advantages of reasonable design, high sensitivity, reliable water-saving performance, simple structure, easy fabrication, and low cost.
Description
The utility model relates to a kind of novel water-saving type water tap.
Existing ordinary tap water tap is to be made up of institutes such as handle with sleeve, valve rod, spool, valve seats, and rotatable handle makes valve rod descending, and the rubber spool is pressed on the valve port, and current are blocked.Spool is a running torque by the people to closing of valve port, and this structure is easy to generate weeping, and reason is: when the handle overtorquing spool easily twisted bad, thereby occur more stubborn, the weeping that is not closed completely more; Next is to use up the water back handle not tighten, and spool and not driving fit of valve port also cause water clock.These weepings are recurrent in factory, school, public place, fully reflect the drawback of the structure existence of existing ordinary faucet.In addition, some have the water tap of time-delay closing function, and the deficiency of existence is: people can only use in the scope of given time and water flow, can not arbitrarily control the time of time-delay closing, be easy to generate the too much or not enough phenomenon of water consumption, also have the situation of necessarily wasting water.Because of can not arbitrarily controlling the size of water flow, inconvenient part is arranged in the use.
The objective of the invention is to overcome the deficiency of above water tap existence, a kind of novel water-saving type water tap is provided, adopt bending moment screw thread and the brand new that utilizes water pressure self acting stop valve mouth.
Now in conjunction with the accompanying drawings 1 and 2 pairs of technical solutions of the utility model of accompanying drawing illustrated.
The utility model system is made up of handle with sleeve, valve rod, spool, valve seat etc., valve rod (2) is contained in the upper body (5), bending moment screw thread (3) is engraved in the inwall that upper body (5) were gone up or be engraved in to valve rod (2), cylinder pilot pin (4) one ends are fixed on the sidewall of upper body (5) or are fixed in valve rod (2) body, and the other end of pilot pin (4) is inserted in the groove of bending moment screw thread (3).When rotatable handle (1), valve rod (2) rotates thereupon, and the interaction by pilot pin (4) and bending moment thread groove moves up and down valve rod, valve seat (6) is fixed in the valve body (8), the center has valve port, and spool (7) is contained in the valve seat (6), is positioned at the same center line of valve port bottom and valve port, spring (9) is equipped with in spool (7) bottom, when valve rod (2) was descending, spool (7) was by being pushed up down, the valve port outflow of fetching boiling water.When valve rod (2) was up, ducted hydraulic pressure impelled it together up with valve rod (2), until valve port is closed to the top power of spool (7).When cutting off the water, there is not hydraulic pressure in the pipeline, spring (9) can prevent that spool (7) from descending, and guarantees to be in closed condition.
As can be seen, bending moment screw thread (3) has 2 different amount from accompanying drawing, and 1. 2. the locking angle discharges angle, is the angle turning point with (A).Its effect is: when pilot pin (4) is in the locking angle of bending moment thread groove, valve rod (2) can rest on arbitrarily angled, can regulate spool and valve port opening, realize control water yield size, when pilot pin (4) was in the release angle of bending moment thread groove, hydraulic pressure was to the frictional force of spool (7) top power up greater than the screw thread cell wall of pilot pin (4) in the pipeline, and valve rod (2) is by jack-up, spool (7) is closed valve port, and current are blocked.So this novel water-saving type water tap is to utilize the pressure of water to close, rather than dependence people's screw-down torque.
The utility model can design when the fine water stream mode, and the release angle that allows pilot pin (4) just enter the gaining twist groove gets final product the self acting stop valve mouth, prevents that water clock from producing, and also do not influence the use of the normal water yield simultaneously.
The utility model compared with prior art has following characteristics:
1: the utility model adopts the bending moment worm structure, and when pilot pin (4) is in when discharging angle, with valve rod jack-up, spool self acting stop valve mouth blocks current to hydraulic pressure, solves the water clock problem of existing ordinary faucet, the realization using water wisely to the last top power of spool.
2: the utility model save-water faucet is not to rely on people's screw-down torque to block current, but utilizes the pressure of ducted water that spool jack-up self acting stop valve mouth is blocked current.
3: the utility model can design when the fine water stream mode, allows pilot pin (4) enter the release angle of gaining twist groove, can realize the self acting stop valve mouth, prevents that water clock from producing, and also do not influence the use of the normal water yield simultaneously.
4: the utility model is reasonable in design, and is highly sensitive, simple in structure, and easily manufacturing is with low cost, is convenient to promote the use of.Adopt this product not only can obtain favorable economic benefit, and will society produce far reaching significance, make water conservation push the new stage to.
