Abstract

A ball-shaped shut off valve of the utility model is a safety device of the water supply line system, whose casing is composed of a water inlet pipe, a water outlet pipe and a ball storage pipe in which a floating ball is put. A venting device is arranged on the upper end of the ball storage pipe. If the faucet which is opened is not closed when water shuts off, the floating ball falls between the water inlet pipe and the water outlet pipe. A water stream enables the floating ball to clog the water outlet pipe, and thus the safety function is achieved. The faucet is closed, and the air in the ball storage pipe is let out through the venting device simultaneously. The floating ball goes into the ball storage pipe, and the faucet is used nornally.

Description

Ball-shape shut off valve

The utility model relates to a kind of valve, particularly a kind of automatic stop valve of cutting off the water (F16K 1/100,31/22,33/00) that is used for water system

After the water tap that uses in water system is at present opened, in water supply line, can not close voluntarily when anhydrous, therefore in case cut off the water, people are usually owing to carelessness is forgotten and closed water tap, after pipeline resumes water supply, just can cause the current waste like this, even flood takes place.In order to address this problem, there is the people once to design a kind of tap water safety installations (GG86203694), its main structure is in a housing water-inlet cavity and sinking and energing cavity to be set, and puts into a sinking and energing mark simultaneously in sinking and energing cavity.Its deficiency is that this device must vertical be installed, and its sensitivity is lower, when the pressure of water hour, can be malfunctioning.

Task of the present utility model provides a kind of and the matching used stop valve of cutting off the water of water tap, and it can close the water route automatically when water supply pipe is cut off the water, and after resuming water supply, the user can open the water route again easily.

The utility model is finished as follows:

A storage bulb is set between intake pipe and outlet pipe, make it to form the T font structure, in the storage bulb bead is arranged, the proportion of its bead should be slightly smaller than the proportion of water, storage bulb and intake pipe and outlet pipe mutual conduction have a venting gas appliance in the upper end of storage bulb simultaneously.As the water tap of opening when cutting off the water is not closed, water in the pipeline will flow to end, and the bead of storing at that time in the bulb will fall between the link position of intake pipe and outlet pipe, when unexpected water supply, the water impact bead makes it outlet pipe is blocked, play by effect, close water tap and utilize venting gas appliance will store the interior air of bulb when draining, because buoyancy of water, bead will rise, enter the storage bulb, just conducting of water route like this, water tap can normally use again.

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

Fig. 1 is a kind of embodiment's of the utility model a longitudinal sectional drawing.

With reference to Fig. 1, the stop valve valve body is made up of intake pipe (9), outlet pipe (12) and storage bulb (13), storage bulb (13) is substantially perpendicular to intake pipe (9) and outlet pipe (12), the three can one-time cast-forming, also can discrete assembling moulding, a bead (8) is put in inside at storage bulb (13), and bead can drop between intake pipe (9) and the outlet pipe (12) along storage bulb (13), and can be between the two (9), (12) flexible motion.Outlet pipe (12) is preferably bell mouth shape (10) with the internal diameter of storage bulb (13) connecting end, so that can coincide with bead (8) is fine, play effectively by effect, if the internal diameter of outlet pipe (12) is greater than the diameter of bead (8), can set up an annular shim at outlet pipe (12) and storage bulb (13) connecting end, to play the effect of blocking bead (8), blocking-up current.Said in the above bell mouth shape (10) can have one or several dribble (11) on the position, in case pipeline resumes water supply, water will ooze water tap by dribble (11), to remind the user.There is a venting gas appliance (14) upper end at storage bulb (13), this venting gas appliance (14) can be made following structure: exhaust handle (1) passes storage bulb cap (3) and stretches in the storage bulb (13), fix an air-vent cap (5) at the inserting end of exhaust handle (1), said air-vent cap (5) can be fixed on the inserting end of exhaust handle (1) by a nut (6), on the face of air-vent cap (5), fix a seal washer (4) by storage bulb cap (3), be equipped with exhaust port (2) on the storage bulb cap (3), exhaust port (2) is at least 1.On the circumferential position of inwall near storage bulb cap (3) of storage bulb (13).Have two salient points (15) or more at least, even be linked to be ring-type, its salient point (15) is in order to support a spring (7), under the effect of spring (7), seal washer (4) on the exhaust handle is closely contacted with storage bulb cap (3), run off from the exhaust port (2) on the storage bulb cap (3) is interior to prevent water.The most handy stainless steel material of said spring (7) is made.For the ease of water supply pipe that the stop valve of originally cutting off the water is packed into, can attack screw thread in the outside or the inside of the water outlet of the water intake of intake pipe (9) and outlet pipe (12).

Originally the working principle of stop valve of cutting off the water is such: when cutting off the water, if the water tap of opening is not closed, water in the valve body will slowly flow to end, the bead of storing simultaneously in the bulb (13) (8) will fall between the link position of intake pipe (9) and outlet pipe (12), when resuming water supply, water impact bead (8) makes it to coincide with bell mouth shape (10) position of outlet pipe (12), so just outlet pipe (12) is blocked, and plays the effect by current.Because the existence of dribble (11), water can pass through dribble (11) and flow out water tap, the user can have not dripping phenomenon according to water tap, (not having the dribble user also can know whether certainly resumes water supply) judges whether to resume water supply, in case water is arranged in the pipeline,, and presses the exhaust handle (1) on the stop valve of cutting off the water simultaneously as long as the user closes water tap, seal washer (4) will break away from storage bulb cap (3), and the gas in the storage bulb (13) just can discharge by exhaust port (2).Under the buoyancy of water effect, bead (8) will rise, and enters the storage bulb, water route conducting again like this, and water tap just can normally use.

The utility model is skillfully constructed, simple in structure, highly sensitive, with low cost, and design outline structure according to actual needs, be applicable to family, dormitory water saving, also can control a plurality of taps by it and make the pipeline main valve, be applicable to collective unit's water savings such as army, universities and colleges, industrial enterprise.
