Abstract

The utility model relates to a waterless automatic closing tap. A valve core is arranged between a water inlet and a water outlet. The closing and the opening of the valve core is controlled by the crank axle arranged on a valve body. The crank axle is provided with a handle. When the running water is supplied and the crank axle pushes off the valve core, the friction force between the valve core and the crank axle is increased by the water function and thus the water tap can not be automatically closed. When the running water is cut off, the friction force between the valve core and the crank axle is decreased, the crank axle can automatically under the function of the handle gravity to prevent the valve core from contacting with the crank axle in order to enable the water tap to be in closing state. The utility model has the advantages of simple structure, convenient manufacture and convenient use.

Description

Waterless automatic closing tap

The utility model belongs to valve type, relates in particular to a kind of anhydrous water tap of closing automatically.

At present, the water tap that people use, spool and handle are fixed together, and are provided with screw thread between spool and valve body, by rotatable handle, just can make water tap close or open.This water tap, when cutting off the water, people forget and close water tap, when coming water, will cause the great amount of water resources waste; By threaded joint, grown by the time with valve body for spool in addition, and screw thread will mesh less than together, and make the water tap subscription rate.

The purpose of this utility model provides a kind of anhydrous water tap of closing automatically that can close automatically when anhydrous.

The utility model is to realize like this, water intake ［ 5 ］ is handed over into 90 degree with the shaft axis of water chamber ［ 9 ］, and between them, be provided with a through hole ［ 8 ］, in through hole ［ 8 ］, be fitted with spool ［ 4 ］, one end of spool ［ 4 ］ contacts with the bending part that is contained in the bent axle ［ 3 ］ on the valve body ［ 7 ］, the end that bent axle ［ 3 ］ stretches out outside the valve body ［ 7 ］ is provided with handle ［ 1 ］, and the nose in the bending part of handle ［ 1 ］ and bent axle ［ 3 ］ is in same direction.

The utlity model has simple in structurely, make, advantage easy to use.When running water pipe had water, rotatable handle made the bending part of bent axle back down spool, because the effect of water is arranged, spool increases with the frictional force of bent axle contacting point, and bent axle can not rotate automatically.When tap water cut-off, owing to the frictional force of spool with the bent axle contacting point reduces, bent axle is under the effect of handle gravity, and rotation makes bent axle can not contact with spool, and reaches the function that water tap is closed automatically automatically.

Accompanying drawing is a structural representation of the present utility model.

Now in conjunction with the accompanying drawings embodiment of the present utility model is described further:

Become a valve body ［ 7 ］ with aluminium alloy casting, make the axle center of water intake ［ 5 ］ and water chamber ［ 9 ］ become 90 degree.And between them, be provided with their a taper hole ［ 8 ］ of connection, in round taper hole ［ 8 ］, be fitted with the spool ［ 4 ］ that is made into bronze, be provided with rubber seal at the same cone shape hole of spool ［ 4 ］ ［ 8 ］ phase-contact surface.Adorn chromium plating or zinc-plated bent axle ［ 3 ］ on valve body ［ 7 ］, the same spool in bending part ［ 4 ］ of bent axle ［ 3 ］ contacts, and the shaft axis of the same spool of shaft axis ［ 4 ］ of bent axle ［ 3 ］ becomes 90 degree.Bent axle ［ 3 ］ stretches out the outer end of valve body handle ［ 1 ］ is housed, and the nose in the same bent axle of shaft axis ［ 3 ］ bending part of handle ［ 1 ］ is in same direction.Convenient for installation and processing, between bent axle ［ 3 ］ and valve body ［ 7 ］, also be provided with sealing cover ［ 2 ］, in order to determine the start or stop position of spool ［ 4 ］, between valve body ［ 7 ］ and handle ［ 1 ］, be provided with locating stud ［ 6 ］.
