Abstract

The utility model discloses a gravity spattering-proof self-closing water-saving tap, which is composed of a tap body (1), a spattering-proof sleeve (9) whose inner cavity forms a horn shape, a T-shaped rod-shaped valve core (2), a sealing ring (3), an averaging device composed of a containing sleeve (4) and a flow equalizing plate (8), and a valve rod guide disc (10). The gravity spattering-proof self-closing water-saving tap can be automatically closed by the water pressure of a water supply pipe and the gravity of the T-shaped rod-shaped valve core (2), and can be opened by utilizing the external force to lift the T-shaped rod-shaped valve core (2) upwards. The utility model overcomes the shortcomings that the use of the existing press connecting type water tap is not convenient, the plug cock type water tap is easy to damage, etc. The utility model which has the advantages of convenient operation, no easy damage, water saving, etc. is suitable for being as the water supply tap in trains, ships, and other public places.

Description

Gravity spattering-proof self-close water saving tap

The utility model relates to the water tap that opens and closes supply channel, the especially a kind of pressure of water and self-closing water saving tap of gravity type splashproof that the slotting gravity of valve closes valve voluntarily of utilizing.

At present, in train, steamer and other public place, the water nozzle of use mainly is elasticity lever type water nozzle and cock-type water nozzle.After being to use, the great advantage of elasticity lever type water nozzle can cut off current voluntarily, be specially adapted to this class of train self water storage capacity and seldom need water-saving occasion, but when this water nozzle uses must with hand pin shoulder bar can water outlet, cause inconvenience to the user, cause trouble especially for cripple's use.The cock-type water nozzle is by the keying water nozzle that rotatablely moves of rotation entity, though be widely used, if be used for train, steamer and other public arena, because frequency of utilization is higher, water nozzle is easily damaged, and forms running water, the waste water source.

Openly a kind of excessively " automatic shop valve " (application number 91214183.2 that is used to control fluid passage of Chinese patent communique; Notification number CN2085883U), this valve is by a valve body with import and export, and head end is positioned at described body cavity and bar portion stretches out the shaft-like spool of the T shape of its outlet and constitutes, and the outlet port end face of described valve body is provided with sealing gasket.This stop valve utilizes the pressure of fluid self to promote the shaft-like spool of T shape and cuts off fluid passage and realize closing, and utilizes external force to promote the shaft-like spool of T shape and connects fluid passage and realize open-mindedly, advantage such as has and structure is easy simple in structure.But when supply channel being controlled, can only flow out the wire current, can not satisfy the needs of actual used water with this stop valve.

The purpose of the utility model, be at the deficiency of above-mentioned technology and provide a kind of supply channel hydraulic pressure and spool gravity of can utilizing to close voluntarily, easy to use, not fragile, water saving and can satisfy the water supply needs is applicable to the self-closing water saving tap of gravity type splashproof that train, steamer and other public place use.

Realize the technological scheme of above-mentioned purpose:

The self-closing water water saving tap of a kind of gravity type splashproof, it comprises, the mouth body (1) that can be connected and have water intake (11) and water outlet (12) with supply channel, head end is positioned at the shaft-like spool of T shape that its water outlet (12) stretches out in described mouth intracoelomic cavity and bar portion, it is characterized in that the self-closing water saving tap of described gravity type splashproof also comprises:

An inner chamber is trumpet-shaped splash-proof casing (9), and this cover links to each other with described mouth body and the water outlet (12) of its inner chamber and described mouth body (1) is connected;

A sealing gasket, this pad are the seal rings (3) that an embedding is attached to described T shape shaft-like spool head end lower end surface and can moves up and down with the shaft-like spool of this T shape.

In the described scheme, the keying of mouth body water outlet (12) is realized by the shaft-like spool of the T shape with seal ring (3), when with this spool lower end of external force pop-up it being moved upward, the water that mouth body water intake (11) enters the mouth body can flow out by the gap between mouth body water outlet (12) and the shaft-like valve core rod of the T shape portion easily; After external force is eliminated, gravity acting in conjunction by the hydraulic pressure and the shaft-like spool of T shape of supply channel, the shaft-like spool of T shape is moved downward and seal mouth body water outlet (12) and can move up and down with the shaft-like spool of T shape owing to described seal ring (3), it acts on a sealing plug that can open and close, can guarantee that not only mouth body water outlet is closed reliably, and for having created advantage in the gap between choose reasonable T shape shaft-like valve core rod portion and the mouth body water outlet (12).As long as this gap of choose reasonable just can provide the water output of satisfying the demand to the user.

Splash-proof casing in the described scheme (9) is mainly used in the current direction sputter all around that prevents by mouth body water outlet (12) outflow.

The position is accurate when moving up and down with the described T shape spool of assurance for the discharge pressure that reduces described splash-proof casing (9), described splash-proof casing (9) bottom can also comprise a uniform device, this device is by a device cover (4) that links to each other with described splash-proof casing (9) and can be loaded on homogenizing plate (8) formation that described splash-proof casing (9) bottom exports by this device cover (4), described homogenizing plate has aperture on (8), the positioning hole (81) that central authorities have the bar portion of confession T shape spool to move up and down.

Also can comprise a stem guiding dish (10) that is used to improve the wear-resisting property of this gravity type splashproof self-closing water tap between described homogenizing plate (8) and the described splash-proof casing (9), this stem guiding dish is one and has the stem guiding dish (10) that supports the guide ring (7) that the bar portion for the shaft-like spool of described T shape moves up and down by strut (6).

Compare with prior art, the utility model can utilize the hydraulic pressure of supply channel and valve rod self-closing, has easy to usely, not fragile, can satisfy the water supply needs, can reach advantages such as using water wisely purpose.Be applicable to that making water tap in train, steamer and other public place uses, and reaches the purpose of the utility model.

Below in conjunction with example and accompanying drawing the utility model is described.

Fig. 1 is the utility model structural representation, for convenience of description, adopts broken section.

User mode figure when Fig. 2 is in open state for the utility model.

In the example (referring to Fig. 1): 1-mouth body, for being connected with supply channel, its top periphery is processed with screw thread.The water intake of 11-mouth body.The water outlet of 12-mouth body.The shaft-like spool of 2-T shape.The 3-seal ring.9-splash-proof casing, its inner chamber are horn-like.4-device cover.The 8-homogenizing plate, there is positioning hole (81) in its central authorities, and the plate body is furnished with aperture.Constitute uniform device by device cover (4) and homogenizing plate (8) in this example.10-stem guiding dish, it has strut (6) and guide ring (7), 5-seal ring.

Big arrow among Fig. 2 shows the direction that external force upwards holds up the shaft-like spool of T shape, and small arrow shows the direction of current.
