Description

Save-water faucet

Technical field

The utility model relates to a kind of valve, the particularly a kind of water tap that can close automatically.

Background technique

All need manual operation when having common water tap now.In some public arenas, some people the leading water of fetching boiling water wash one's hands or scouring pad after often forget and close, cause the long-time flowing water phenomenon of water tap.Simultaneously, some people is firmly excessive often in switching manipulation, and the handle of water tap or the hermetic unit in the valve body are damaged, and influences its working life.

For this reason, there are many people to propose the various water taps that can close automatically, provide " the adjustable water tap of closing automatically " as Chinese patent 942112784, it is made up of parts such as set screw, deflating cap, screw rod, seal ring, spring, spring seat, valve bodies, utilize the spring roof pressure spool of spool bottom, water tap is sealed.Although this water tap can be closed automatically, its structure is quite complicated, makes the cost of product higher.In addition, the seepage phenomenon also appears in actual use easily.

What up to the present, do not occur also that a kind of structure is more satisfactory, practicability is stronger closes water tap automatically.

Summary of the invention

The purpose of this utility model is in order to address the above problem, provide a kind of simple in structure, practicability is strong, the save-water faucet that can close automatically.

The purpose of this utility model realizes by following technical proposal: this save-water faucet comprises valve body, outer handle, the interior sealing seat and the valve rod that links to each other with sealing seat of valve body of valve body, sealing seat is with sealing gasket outward, socket spring on the valve rod, the two ends of spring link to each other with valve body with sealing seat respectively, handle connects with the upper end of valve rod by a screw, the upper-end surface of valve body is the male and fomale(M﹠F) of a undulate, and also is provided with several pellets shot from a slingshot between valve body and the handle.

In this save-water faucet, the spring roof pressure on the valve rod makes the sealing gasket that is placed on the sealing seat be close to the interior sealing surface of valve body, thereby water tap is closed on sealing seat.Simultaneously, this moment, pellet shot from a slingshot between handle and valve body was in the trench place of valve body upper end male and fomale(M﹠F).In the handle with sleeve process, rely on the frictional force between handle inboard and the pellet shot from a slingshot to make pellet shot from a slingshot along with handle rolls, pellet shot from a slingshot is rolled to the place, protruding peak of male and fomale(M﹠F) by the trench place of male and fomale(M﹠F).Like this, cause the handle vertical promotion, drive valve rod and rise.Thus, the sealing gasket of valve rod end can break away from sealing surface, and water tap is opened.After release handle, the pulling force of spring can make pellet shot from a slingshot by the trench place of rolling back, the protruding peak of male and fomale(M﹠F), and valve rod and sealing gasket all reset, and water tap is closed again, have realized the function of closing automatically.

In order to increase the frictional force of pellet shot from a slingshot and handle, the interior edge face of handle preferably also is a male and fomale(M﹠F).

In order to prevent that the position that pellet shot from a slingshot rolls from deviation can not occur, can be provided with a limit stoper at the pellet shot from a slingshot place.

Above-mentioned limit stoper is a circular plate of being located between valve body and the handle, has on the circular plate and pellet shot from a slingshot equal number and equally distributed circular hole, and the internal diameter of circular hole is slightly larger than the external diameter of pellet shot from a slingshot, and each pellet shot from a slingshot all is in the circular hole of circular plate.In use, circular plate rotates along with the rolling of pellet shot from a slingshot.

Compared with prior art, the save-water faucet that provides of the utility model has following advantage:

1, this water tap has utilized the elastic force of spring to realize closing automatically, and it is simple and reasonable, easy to operate, has higher utility.

2, in the using process of this water tap, valve rod is vertically lifting only, and does not rotate, so the sealing between valve rod and the valve body, between sealing gasket and the valve body is influenced seldom, is not prone to the seepage phenomenon, can prolong the working life of water tap.

Embodiment

As shown in Figure 1, this save-water faucet comprises parts such as valve body 1, valve rod 2, sealing seat 3, sealing gasket 4, spring 6, handle 5 and pellet shot from a slingshot 8.The sealing gasket 4 general rubber materials that adopt are made, and are enclosed within on the sealing seat 3.Spring 6 two ends that are socketed on the valve rod 2 link to each other with sealing seat 3 with valve body 1 respectively.Sealing surface 1a is arranged in the valve body 1, when spring 6 with sealing seat 3 and sealing gasket 4 roof pressures when sealing surface 1a goes up, this water tap is in closed condition.

As shown in Figure 3, the upper-end surface of valve body 1 is a male and fomale(M﹠F) 10.In the present embodiment, three trench 10a and three protruding peak 10b are arranged on the male and fomale(M﹠F) 10 of valve body 1.Corresponding, be provided with three pellets shot from a slingshot 8 between valve body 1 and the handle 5.Simultaneously, as shown in Figure 4, three equally distributed circular hole 9a are arranged also on the circular plate 9.

Connect by screw 7 between handle 5 and the valve rod 2.Handle 5 is closely buckled in the upper end surface of valve body 1, and the inner side surface of handle 5 is pressed on the pellet shot from a slingshot 8.Like this, just can rely on during handle with sleeve 5 frictional force that pellet shot from a slingshot 8 is rotated together with circular plate 9.

In handle with sleeve 5 processes, pellet shot from a slingshot 8 and then rolls together, is rolled to 10b place, protruding peak by the trench 10a place of valve body 1 upper end male and fomale(M﹠F) 10, and valve rod 2 is risen jointly together with sealing seat 3 and sealing gasket 4.Obviously, handle 5 is as long as rotate 60 ° in the present embodiment, and water tap just will be become the state of complete opening by closed condition.After the release handle 5, water tap can be closed under the effect of spring 6 again.

As shown in Figure 2, between handle 5 and screw 7, also be provided with bearing 11 in the present embodiment.Because in handle 5 rotation processes, screw 7 is fixed, can improve the flexibility that handle 5 rotates and resets so set up bearing 11.

This save-water faucet is connected to the water outlet place of tap water, is particularly suitable for local use such as school, dining room or public place.
