Abstract

The utility model relates to a timing tap water valve. When a timing button on the timing tap water valve is rotated by hand, the timing tap water valve is opened. A mechanical timing device is driven by that an impeller is impacted by pressure generated when tap water flows out, and the timing tap water valve is automatically closed. The mechanical timing device and a valve base form an integral body. The utility model is the timing tap water valve which is especially suitable for public places. The timing tap water valve can substitute a water tank in a water flushing closet. The utility model saves water, but does not consume energy.

Description

Timing tap water valve

The utility model relates to a kind of running water valve, is specially adapted to the running water valve of public place, and can replace the water tank of water-closet.

The running water valve of public place is not often closed after people use because of a variety of causes now; Water tank in the water-closet, defecating, urinate all need be with the same water yield.These have all caused the waste of water resources.The automatic running water valve of present existing laser controlling though reached the purpose of water saving, has consumed electric energy.

The purpose of this utility model is will provide a kind of to strike the timing running water valve of closing automatically behind the valve from the beginning with the hand, the purpose that does not consume energy to reach water saving according to the water time.

Timing device of the present utility model and running water valve form a whole, with the fixing timing device of two bearing supports, timing device is that an impeller leaning against valve base water outlet place obtains power and drives mechanical timer and close running water valve automatically on the running water valve base.Impeller links to each other with worm screw, and the worm and wheel ring gear matches.One side of timing wheel is inserted in the worm gear ring gear, there is the reed of a band pin tooth to be fixed on the timing wheel in this side of timing wheel, timing disc has two of refuting bar one side to refute bar to be inserted in reed both sides in the timing wheel, has regularly turned round pin tooth one side and has inserted timing disc support roller one side is arranged.The opposite side of timing wheel is recessed a wheel, follower lever one end cooperates with recessed the wheel, and the follower lever the other end has one section screw thread and has one regulates turn-knob, regulates turn-knob below and lever mated, have a spring to head on this end of lever on the valve base, the lever the other end links to each other with valve.

Task of the present utility model is finished in the following way: when rotating with hand when regularly turning round, and the moving timing disc of twisted strip regularly, the bar of refuting of timing disc is refuted reed curved, and reed is drawn in the pin tooth in the timing wheel, refutes bar and drives timing wheel and rotate.Loose one's grip when turning to the appropriate location, reed goes out the pin tooth top with the worm gear ring gear to match; The recessed wheel of timing wheel opposite side simultaneously under the driven masthead, follower lever drive lever, the lever harrow running water valve is opened, and water impacts wheel rotation after by valve, and timing reset begins.Before closing to an end when resetting, follower lever is given power on the recessed eccentric arc of taking turns by the spring of lower end, makes follower lever get back to initial position, valve closing rapidly.When not needing regularly, rotatable timing is turned round directly and is resetted.

Further specify the regularly structure of running water valve below in conjunction with accompanying drawing:

Fig. 1 is a structural drawing of the present utility model.

Fig. 2 is plan view and two sectional views of valve base.

Fig. 3 is the plan view and the sectional view of worm gear ring gear.

Fig. 4 is the plan view and the left view of timing wheel.

Fig. 5 is the plan view and the left view of timing disc.

Plan view and the left view of Fig. 6 for regularly turning round.

Fig. 7 is the plan view and the plan view of two bearing supports of timing device.

In Fig. 1, a steamboat is arranged at follower lever 1 top, and there is one section screw thread the bottom and has regulates turn-knob 2, and regulating turn-knob 2 is to regulate the size that follower lever 1 is come control valve 4 to open by the size of top down stroke; O type rubber ring 5,7 is used for water shutoff; Worm screw 6 links to each other with impeller 8; Pin tooth 9 links to each other with reed 10, and reed 10 links to each other with timing wheel Fig. 4.In Fig. 2, the top is the step profile figure of valve base, and the centre is the plan view of valve base, and the below is the removed sectional view at valve base water outlet place, and hole 11 is fixed supporting frame Fig. 7 places.Recessedly take turns a relative side and insert in worm gear ring gear Fig. 3 with having on timing wheel Fig. 4, and this side refutes bar 12 1 sides with timing disc Fig. 5 and cooperate, the support roller 13 of timing disc Fig. 5 cooperates with bearing support 15.Regularly turning round Fig. 6 has pin tooth one side to be inserted on the support roller 13 of timing disc Fig. 5.

Have the recessed side center of taking turns to insert an axle at timing wheel Fig. 4, an end of axle is fixed on the bearing support 14.

The utility model is reasonable in design, timing wheel recessed take turns breach institute to central angle less than inboard adjacent two teeth of worm gear ring gear institute to central angle, the end that resets is not the rotation by impeller, but take turns applied force on the eccentric arc to recessed by follower lever, the effect of eccentric arc makes that also the torsion of regularly turning round reduces greatly in addition.The shaft centre line of impeller not with the outlet pipe medial axis in same plane, can make impeller obtain big moment.

Claims

1, a kind of timing running water valve, by the impeller that is arranged on the valve base, worm screw, worm gear ring gear, timing wheel, regularly turn round, timing device that follower lever and turn-knob, lever and valve are formed, it is characterized in that integral body of said timing device and valve base formation.

2, by the said timing running water valve of claim 1, its specific said timing device is in the outlet pipe direction one impeller to be arranged, and impeller links to each other with worm screw, and the worm and wheel ring gear cooperates.

3, by the said timing running water valve of claim 1, the said timing device of its feature is that worm gear ring gear inboard has tooth, and is enclosed within timing wheel one side, has the pin tooth to link to each other with reed in this side of timing wheel, and reed links to each other with timing wheel; What cooperate with this side of timing wheel is timing disc, has two to refute bar and be inserted in the reed both sides on timing disc one side; The timing disc opposite side is turned round with timing and is linked to each other.
