The valve plug (1) is covered by a flexible envelope (7) with a sealing wing rim (6). The utility model has the characteristics of no leakage, water cut-off self-closing and convenient use.

Description

Energy-saving water valve

The utility model belongs to valve, and especially daily normal pressure valve is made the field.

Present spiral water valve, the long slightly sealing surface wear that promptly easily causes of spreadable life produces and leaks.Recently, though there are some anti-leak water valves to occur, its anti-leak function is unsatisfactory, is difficult to drop into actual use.

The purpose of this utility model is a kind of Energy-saving water valve of design, makes its above shortcoming that can overcome prior art, and has function easy to use and the energy water-stopping self-closing concurrently.

The purpose of this utility model is to realize by following design.

In the water valve of forming by valve body, intake-outlet, spool etc., constitute the spool elevator mechanism by valve plug, lifting bar, lifting slider and cam handle etc.One end of lifting bar connects firmly on valve plug, and its other end and lifting slider link.Cam handle is supported by solid clever stand on valve body and connects with the upper end of lifting slider is concentric.Valve plug is coated by a flexible cover that has sealing wing edge, has on the big envelope to make lifting bar pass through therebetween via hole, and the big envelope wing connects firmly along being press seal with valve body.

After adopting structure as above, whole spool is subjected to the control of cam curve, and optionally the turn cam handle raises valve plug or reduces to obtain the current of different flow.Because the moving part of valve plug elevator mechanism is by the big envelope insulation package, so can not produce leakage.In addition; after cam was threaded to a certain position and comes water, the effect of pipeline inside water pressure made the cam convex edge be subjected to a downward power, made convex edge and support stand keep enough positive pressure to keep the invariant position of cam; when cut off the water midway; hydraulic pressure disappears to the downward active force in convex edge, the positive pressure between convex edge and support stand be decreased to less than its handle from gravity, handle falls automatically; valve plug is closed automatically; when coming water once more, valve still is in the pass closed state, the protective action that playing cuts off the water closes automatically.In addition, unlatching of the present utility model or close and only need lift or can finish by lower handle, operate very easy, if only need water in short-term, the handle of closing gently can be connect downwards again, lifting slider is moved on slightly, can obtain current in short-term, hand is pressed water promptly, and the dried up automatic stop of hand is especially practical in some public washing occasions.

Description of drawings is as follows:

Fig. 1 is the utility model embodiment's a sectional view (pass closed state).

Fig. 2 is the utility model embodiment partial sectional view (a unlatching attitude).

Below in conjunction with accompanying drawing structure of the present utility model is described in further detail.

From Fig. 1 and Fig. 2, can see, by valve lift up 1, lifting bar 2, lifting slider 3 and cam handle 1 constitute the spool elevator mechanism, an end of lifting bar 2 connects firmly on valve plug 1, its other end and lifting slider 3 link.There is a hole 10 centre that connects firmly the stand 5 on valve body, and lifting slider is by sliding therebetween, cam handle support by stand 5 and with 11 concentric connections of upper end of lifting slider.Valve plug 1 is had the flexible cover 7 of the sealing wing along 6 by one and coats, and has on the big envelope to make the via hole 8 of lifting bar 2 by therebetween, and the sealing wing is press seal along 6 with valve body and connects firmly, thereby makes pipeline and spool moving part isolated.Outer cover 12 plays a part attractive in appearance and spacing to cam handle.

In the closed state of the pass of Fig. 1,, can open the situation of water valve pie graph 2 if lift handle by the hollow arrow direction, can find out in the unlatching attitude of Fig. 2, lift handle, cam will move on the slide block 3 in the turn process, slide block 3 promptly drives on the lifting bar 2 drive valve plugs and moves, and valve port is opened, and is in the water supply attitude.Be subjected to the effect of pipeline inner pressure water, cam convex edge 9 is close to stand 5, and its frictional force makes the cam handle holding position constant greater than the handle gravity of conducting oneself with dignity, in case carry on handle, valve just is in the unlatching attitude always.If cut off the water therebetween, the pressure of pipeline water disappears, cam convex edge and stand no longer are close to, its frictional force is less than the handle gravity of conducting oneself with dignity, handle is then whirlpooled down automatically, and valve is returned to the pass closed state, also can not open automatically when coming water again, can play the effect of water-stopping self-closing, this function is particularly important for the area that often cuts off the water.

In the closed state of the pass of Fig. 1, if by taking over handle under the filled arrows direction, valve plug is slightly opened, supplied water in short-term, hand is by i.e. water, and hand is from then cutting off the water supply.

Water flow when opening attitude for making is controlled, and the convex edge 9 of cam should have corresponding curved surface structure, preferably makes involute, and valve plug can be realized different folding degree, and current are changeable.

Basic scheme of the present utility model can not only be used for water valve, also can be used for air valve etc., and is especially particularly suitable as the gas pipeline Safety valve of stopping the supple of gas or steam self-closing.
