Abstract

The utility model relates to a straight sealing type tap which is used for sealing an inlet of a valve body by means of water pressure. The utility model is characterized in that an annular handle which is rotated around an axis is utilized to push a hollow valve rod to do reciprocating linear motion through an annular inclined plane of an inner hole of the annular handle, and therefore, the tap is opened or closed to regulate water quantity. When water is in a pipe, the annular handle can be locked at any opening position by the pressure of the water, and the outflow of the water can be maintained with definite flow quantity. Once the supply of the water is stopped, the pressure of the water disappears simultaneously, the annular handle is recovered to zero position under the action of a small pressure spring, and therefore, the function that the tap can be closed automatically when the water is not supplied is realized. Because of the adoption of a straight sealing structure, the tap has good sealing property. Because the inner part of the valve body is not provided with a screw thread, the service life of the tap is extended. The function that the tap can be closed automatically when the water is not supplied causes the tap to have the advantages of water saving and safe use. The utility model is especially suitable for being popularized and used in cities and districts where the supply of tap water is in a tension state.

Description

The drill point hair style is anhydrous from turning off the tap

The utility model belongs to the water supply utensil

Its switching of existing water tap generally all is manually-operated.And in the area of water supply gets, or the higher building of the number of plies if do not have current after water tap opened, and is forgotten it is closed, in case come water will waste a large amount of tap water, even more serious is cause water overflow the room, bring disaster to the serious consequence in neighbourhood

The purpose of this utility model provides a kind of new type water tap that can close automatically after cutting off the water suddenly again under anhydrous in the pipeline or the water supply state, to realize the target of water saving and safe water

The utility model is achieved in that the pressure that utilizes water seals and the handle lock of water tap is fixed on arbitrary position of its unlatching, in case and after cutting off the water in the pipeline, disappearance along with water pressure, its handle is at the external force effect of Returnning spring reset to zero next time, thereby realizes anhydrous from the purpose of closing

The novel structure of this realization is as follows: make 90 °～120 ° conical surfaces in upper end, valve axis hole, with the lower end be the hollow valve rod chewed of water from the valve axis hole upwards the Shen go out, put rubber sealing boot in the top, the following conical surface of stuffing box gland is made 90 °～120 ° inverted cone surface, plays seal action with cone match on the valve body.At this moment, if with hollow valve rod along moving on its axis, water can be from entering its inner chamber through the uniform tank of crossing in hollow valve rod upper end between two conical surfaces, outflow from water is chewed, water tap promptly is unlocked, reversing motion then can be closed water tap.

Hollow valve rod moves up and down by following structures shape along its axis:

Be pressed into and make its inner to enter part annular groove left part on the valve body from the rectangular hole of annular hand grip upper end slide block, simultaneously a stainless steel small pressure spring is embedded in the circular groove, this moment, annular hand grip can only rotatablely move as the part around valve axis.

Hollow valve rod both wings enter valve body lower portion "

" in the shape groove, limiting it can only do reciprocating linear motion.

The endoporus step surface of annular hand grip is made the form of two groups of annular slopes, holds the lower inclined plane of hollow valve rod both wings, and when annular hand grip rotated, this inclined-plane forced on the hollow valve rod and moves, and water tap is unlocked.Otherwise under the pressure effect of water, hollow valve rod moves down, and water tap is closed.

The anhydrous self-off function of this water tap is achieved in that when being rotated counterclockwise annular hand grip the stainless steel little spring in the valve body circular groove is compressed, and has the trend that resets.When having water to pass through in the water tap, the pressure of water can be locked in annular hand grip on arbitrary position of unlatching, to keep the stable of flow.In case cut off the water, above-mentioned water pressure disappears synchronously, thus annular hand grip the promotion of little spring next time reset to zero realize anhydrous self-off function.

Further specify 26S Proteasome Structure and Function of the present utility model below in conjunction with accompanying drawing.

Fig. 1 is an erection drawing of the present utility model.

Fig. 2 is the sectional drawing by slide block and valve body circular groove symmetry plane.

Fig. 3 is the sectional view of annular hand grip.

Fig. 4 is the plan view of annular hand grip.

Fig. 5 dissects unfolded drawing for the cylinder of step surface in the annular hand grip.

Fig. 6 be valve body lower end "

" the shape groove cooperates schematic representation with hollow valve rod both wings.

Among the figure, 1-rubber sealing boot, 2-valve body, 3-elbow, 4-slide block, 5-small pressure spring, 6-annular hand grip, 7-hollow valve rod.

As shown in the figure, rotate counterclockwise annular hand grip (6), drive slide block (4) and slide in the part annular groove of valve body (2), small pressure spring this moment (5) is compressed.Simultaneously, the endoporus annular slope of annular hand grip (6) forces on the hollow valve rod (7) and moves, and makes to produce the gap between the conical surface of rubber sealing boot (1) and valve body (2), at this moment, just therefrom and through hollow valve rod (7) top the uniform tank of crossing enters its inner chamber to water, chews discharge from the water of lower end.Obviously, regulate the rotation angle of annular hand grip (6), can change the gap length between the above-mentioned sealing surface, thereby reach the purpose of regulating water-quantity.When in the pipeline water being arranged, water passes to annular hand grip (6), slide block (4) to the pressure of rubber sealing boot (1) by hollow valve rod (7), makes that the friction between slide block (4) and valve body (2) circular groove increases, play locking annular hand grip (6), the effect of stablizing selected flow.In case cut off the water, above-mentioned water pressure disappears synchronously, and under the effect of small pressure spring (5) reposition force, annular hand grip (6) is got back to zero-bit, realizes the purpose of cutting off the water and closing certainly.
