Abstract

The utility model relates to a water faucet, which is invented in connection with the prior traditional water faucet. The water faucet consists of a handle, a pin, a compression rod, a floating ball, a water seal, a limit bracket and a connecting nut. One end of the handle is an arc clinohedral and the other end is a lever. The compression rod is below the handle and the lower end of the compression rod presses against the floating ball. The utility model solves the problem that the traditional water faucet fails to turn off automatically when a water supply failure occurs but the water faucet remains turned on and thus a water escape is caused. Moreover, the utility model maintains the advantages of the traditional water faucet that the structure is simple, the cost is low, the material is easy to obtain and the water consumption can be adjusted at will. The utility model utilizes the interaction force of water pressure, buoyancy and so on to achieve the function of an automatic turnoff when the water supply failure occurs and a manually operated turnoff is needed, therefore, no other auxiliary energy sources are needed; in addition, the utility model is hard to damage and can replace the traditional water faucet directly. The utility model is particularly applicable to the areas frequently hit by a water supply failure, such as storied buildings, families and other public places.

Description

Anhydrous automatic turn-off water tap

Affiliated technical field

The utility model belongs to fixed buildings feedwater, draining class, a kind of water nozzle that can close automatically when anhydrous.

Background technique

Traditional water nozzle that we generally use now, all be opening or closing of manual form, very easily cause " metalling run out " during improper use, mostly its reason is because when cutting off the water, forget and close water nozzle and after coming water, take place, use this traditional water nozzle bring inconvenience can for our daily life.Other type has the water nozzle of automatic delay function, is changeless because of its waterdrainage amount and discharge time again, so need water can cause waste, need water frequently unlatching again for a long time, so this kind water nozzle only is applicable to some occasion after a little while.

Summary of the invention

Purpose of the present invention just provides a kind of water nozzle that has the automatic closing function device under anhydrous situation.In order to overcome the shortcoming that traditional water nozzle can not be closed when anhydrous automatically.

The technological scheme that its technology that solves the utility model adopts is: employing float ball goes controlled water flow below being positioned at the water seal water outlet in faucet body.Withstand on the float ball with the constrictor lower end, but the upper end withstands on dowel fixes in the faucet body flexible motion and to have certain work orientation angles, an end be that camber clinohedral, the other end are on the camber clinohedral of lever and the center of gravity handle that is positioned at the lever side, goes to realize the mutual control of handle and float ball.When hydraulic pressure being arranged in the water pipe and is closed condition, handle is in horizontal position, because the point of contact of constrictor is the lowest part of handle curve slope, make constrictor not produce active force to the float ball, again because the buoyancy that water produces the float ball adds that the interior effect of water pressure of pipe is in water seal, make the float ball water outlet that blocks water seal place tightly, the interior water of pipe can not be flowed out.When needing water, upwardly open handle and by the cambered surface of its curve slope the pressure that constrictor produces is acted on the float ball, make the float ball move down the back and form the space with water seal, water promptly flows out in the pipe.The angle control that the water-outlet quantity size is then opened by handle.Because water reacts on handle and the pin by constrictor the buoyancy of float ball generation and the active force of pressure and current in the pipe, because of handle is a clinohedral, so the decomposing force that produces makes a side of handle and its faucet body surface of contact place produce bigger friction, add the friction that produces between upper handle and the pin constrictor, the sliding force that is squeezed and is produced greater than the arc shaped surface of the self gravitation of handle and handle, handle is on the static position of required any angle, has kept the state of discharging water.During water, do not press handle down, can close water nozzle.When cutting off the water, when promptly whether there is water or not in the pipe presses (or pipe is interior anhydrous), lose the pressure that inner pipe water pressure produces the float ball this moment to the water sealing part, again because the design of the buoyancy of float ball adds the weight of constrictor in the weight that is substantially equal to handle, therefore the float ball is not to there being the effect of pressure between handle and the pin, so the friction that each one produces is less than the own wt of handle, make handle can only be in level, the enable possition that can't keep any angle and stop, thereby the function of having closed automatically after having realized cutting off the water.

The beneficial effects of the utility model are: the utility model has kept the traditional water mouth structure simple, easy to use, has also had the self-off function when anhydrous.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified:

Figure (1) is the schematic diagram of the utility model water nozzle:

(1) handle, (2) pin, (3) constrictor, (4) float ball, (5) among the figure (1) (on), (in), (descending) water seal, (6) position-limited rack, (7) attaching nut, (8) (on), (descending) faucet body.

Embodiment

In figure (1), handle (1) with pin (2) be fixed on (on) in the faucet body (8), handle (1) should move freely, its work orientation angles should be in the horizontal direction up and down 60 spend in, and its radian, surface slope, weight should be suitable.Constrictor (3) upper end contact with place, handle (1) camber inclined-plane, and the lower end contacts with float ball (4), the centre by (on) faucet body (8) is spacing and can be mobile flexibly up and down.Float ball (4) is arranged in (descending) faucet body (8) () water seal (5) below, and is spacing by position-limited rack (6), and its size that produces buoyancy should design in the weight that is substantially equal to handle (1) and add that the weight of constrictor (3) is advisable.Water seal (5) divides (on), (in), (descend) three places, (on) in the middle of the water seal (5) with constrictor (3) sealing, edge with (on) faucet body (8) seals, its elastic telescopic degree should be advisable not influence moving up and down of constrictor (3).(in) water seal (5) be positioned at (on), (descending) faucet body (8) middle part, its internal orifice coincide in float ball (4) cone place.(descending) water seal (5) be equal to (in) its position of water seal (5) is opposite.Position-limited rack (6) is positioned at float ball (4) on every side, should be able to limit the normal operation position of float ball.Attaching nut (7) be positioned at (on), (descending) faucet body (8) joining place.(on) faucet body (8) and handle (1) side that produces friction should make and can produce friction bigger shape or add the big antifriction material of friction ractor between it.

Claims (1)

1. A kind of anhydrous automatic turn-off water tap, in faucet body, comprise combination in order such as handle, pin, constrictor, float ball, water seal, position-limited rack and attaching nut, it is characterized in that: having an end is the camber clinohedral, the other end is the handle that lever and its center of gravity are positioned at lever one side, be fixed on flexibly on the faucet body with certain work orientation angles with pin, a constrictor upper end withstands on the camber clinohedral of handle, the lower end withstands on the float ball, and the float ball is positioned at faucet body water seal water outlet below.
