Abstract

The utility model relates to an automatic water cutting off device for resupply on water cut-off, which is composed of an automatic water cutting off device and a water discharging tap which are connected. When tap water is cut off, the automatic water cutting off device cuts off the passage of the tap water. When the tap water is resupplied, even if the tap is not closed, the tap water can not flow out. The utility model solves the phenomenon that water is wasted because the tap is not closed when the tap water is resupplied after the tap water is cut off. The tap of the utility model, which has the advantages of simple structure, convenient operation, and high durability, is especially suitable for being arranged on a tap water pipe in a public place.

Description

Automatic water turn-off device for resupply on water cut-off

The utility model relates to a kind of water closing device of installing on the running water pipe.

As everyone knows, the device that is used at present to close water on the running water pipe is a water valve, is commonly called as tap.Along with the expansion in city, the increase of water consumption, tap water in short supply, supply falls short of demand often, and the phenomenon of cutting off the water also often takes place.Particularly summer, the demand contradictory of tap water is more outstanding.But, one side water service anxiety, the wasting phenomena of tap water is very serious on the other hand.Why? because people open tap when being everlasting the tap water stop supplies, there is not water just not remove to close or forgotten cutout cock.Just let alone gravity flow when tap water supplies again like this.Public place particularly, the phenomenon that tap water pours off in vain is very serious, puts sometimes or even all through the night not stop, and causes tens tons up to a hundred tons tap water waste.Therefore, the tap that uses on the existing running water pipe has improved necessity.

The purpose of this utility model provides a kind of resupply on water cut-off automatic water turn-off device, with solve after the tap water stop supplies cutout cock do not cause tap water again for the time problem of wasting water.

Below in conjunction with accompanying drawing the utility model resupply on water cut-off automatic water turn-off device is carried out detailed narration:

Fig. 1 is a structure sectional view of the present utility model;

Fig. 2 is the zoomed-in view of A-A direction among Fig. 1;

Fig. 3 is the schematic representation of locating rotating switch (13) among Fig. 1;

Fig. 4 is the view of the B-B direction of Fig. 3.

As shown in Figure 1, the utility model resupply on water cut-off automatic water closing device is is partly connected and composed by automatic water-closing device and bleeder cock two, automatic water-closing device by overcoat (1), Floating drum (2), push rod (3), upper shield (4), axle bolt case (5), spring (6), axle door bolt (7), axle door bolt lid (8), stay cord (9) consist of. Overcoat (1) shape is a circular sleeve, and the overcoat wall of its underpart is provided with water inlet (10) and delivery port (11). Floating drum (2) is the stopper with conical head, is contained in the overcoat (1), and push rod (3) is connected with floating drum (2), and axle bolt case (5) shape is T word shape, and it is connected the middle part of upper shield (4). And entangle push rod (3), and spring (6), axle door bolt (7) are located in the axle bolt case (5), and stay cord (9) passes axle door bolt lid (8) and is connected with axle door bolt (7). Bleeder cock is partly by faucet (12), locating rotation switch (13), water plug (14), cover plate (15), rotary handle (16), dog screw (17), cover screw (18) consist of, locating rotation switch (13) is cylinder, have intake chamber (19), locating slot (20), water consent (21) on the locating rotation switch (13), shown in Fig. 2,3,4. Water plug (14) shape is screw-like, water consent (21) coupling with locating rotation switch (13), cover plate (15) is contained on the faucet (12) with cover screw (18), with cover locating rotation switch (13), rotary handle (16) passes cover plate (15) and is connected with locating rotation switch (13). Dog screw (17) is located at the right side of faucet (12), and the termination of dog screw (17) is inserted in the locating slot (20) of locating rotation switch (13).

The operation principle of the utility model resupply on water cut-off automatic water closing device is such: the control action the when automatic water-closing device in this device plays tap water cut-off and supplies, on-off action when the tap of this device plays water service, the just quite now effect of water tap. When the running water stop supplies, and the interior water of overcoat (1) is when having flowed, because the Action of Gravity Field of floating drum (2) bars up the water outlet in the water jacket (1) Mouthful, along with driving push rod (3), the decline of floating drum (2) descends thereupon, at this moment, and the end of blocking push rod (3) of axle door bolt (7) horizontal displacement under the elastic force effect of spring (6). When running water supplies again, because the effect of axle door bolt so that floating drum (2) is close to delivery port, stops that running water does not enter tap partly. Even at this moment tap is partly opened, running water can not flow out yet. If need discharge water, must move right with stay cord (11) pulling axle door bolt (7) just to make floating drum (2) at the effect float downward of running water, and at this moment running water enters in the overcoat (1) from water inlet (10), enters tap partly by delivery port (11) again. The tap operation principle partly of this device is such, make it water plug (14) stub end sealing water inlet pipe (23) by handle (16) rotational positioning rotating switch (13), and at this moment, tap is with regard to contract fully. If find that tap leaks, it is just passable only to need to regulate dog screw (17). By handle (16) rotational positioning switch (13), make intake chamber (19) and water inlet pipe (23) UNICOM, at this moment, running water just enters outlet pipe (22) by water inlet pipe (23) to intake chamber (19) and emits, tap is from being closed to standard-sized sheet, and handle (16) rotates 90 °, as shown in Figure 2.

The utility model, easy to use, open and close flexibly, be installed in the phenomenon of wasting water in the time of preventing from the running water pipe to supply again after tap water from stopping, having water-saving function.
