Abstract

A new water saving tap relates to fast-actuating, controllable flow, automatic delayed turning off, and non-interfering device, in particular to a time delay mechanism of an inner trepanning piston. A slippery hollow water valve shaft (8, 9) which is connected with a screw, with step and equal outside diameter, whose lower part is provided with a plurality of horizontal perforations (6), is arranged between the up valve body and the down valve body. The hollow water valve shaft is connected with a sealing ring (5) of the low valve body in slippage, which is used as a water outlet. An inner trepanning piston (10) which is connect with an inner sealing ring (25) of the piston is arranged in the upper part of the hollow water valve shaft, and an outer sealing ring (26) is connected with the up valve body in slippage. A circular shaft of cone apex (14) moves upward, and the water in the up valve body (15) flows down through a hole (21), and the water valve shaft and the piston moves upward, and the water outflows from (3) by (7) through (6), then infiltrates on the piston slowly from a shaft hole of the cone apex (13) through a cone needle (13), and then pushes the piston and the water valve shaft to turn off the tap with time delay after filling up. The tap also can be turned off fast by pushing down the water valve shaft for saving water.

water valve axle

8,9 and close water tap downwards.Also can before being full of, close water tap by the downward setting-out

valve shaft

8,9 of shell at any time.Move up the water valve wheelbase from control flow rate thereby reach selected, close the purpose of water tap downwards by the water valve axle rapidly.

The beneficial effects of the utility model are, both be provided with can be brisk upwards or left-handed rising flow-controllable ground open current, install " long delay is decided the water yield " again additional, self-closing device mechanism on again can the be brisk downward device that close current rapidly.The control that is independent of each other of (1 minute to 5 minutes) and two mechanisms, thus reach water saving, practical effect.

Description of drawings:

Fig. 1 is the whole-cutaway view of the utility model embodiment.

Fig. 2 is the shell partial sectional view of the utility model embodiment.

Embodiment:

Water tap shown in Figure 1 is established two valve bodies up and down.Going up is control valve body 1, is water-in and water-out valve body 2 down.Establish a water-exit vertically hole 7 in following 3 same aspect the place aheads, valve inleting water road, be provided with one in the hole by permeable opening wearing the O RunddichtringO 5 that groove ring washer 4 limits, establish the smooth hollow

water valve axle

8,9 that two sections scyewed joint and outer diameter equate again, this hypomere 8, end establish a plurality of cross hole slot 6 therewith the osculum seal ring be slidingly connected and be exhalant canal.

The hole inner seal ring 25 that water valve axle epimere 9 passes the interior trepanning piston 10 of special setting is slidingly connected with it, the slick and sly moving formation pressure chamber 15 that connects in piston peripheral hardware O RunddichtringO 26 and the upper valve body bottom.

Vertex of a cone shape roundlet axle 14 with the level outside the hollow is lived with spring 11 crimping by 12 places, round platform rank in this water valve axle epimere top, this roundlet axial cone pushes up downwards and seal ring 24 crimping of water valve axle hypomere upper top, and the seal ring 19 that upper valve body top cover 16 is passed on its circular shaft top connects with shell 17 usefulness screws 18.

Swivel body inner circumference shown in Figure 2 establish the symmetry that is provided with on symmetrical two Xiao's axles 28 and the upper valve body excircle, can make two Xiao's axles can be vertically, opening chute 27 that again can left-handed rising is slidingly connected, and left-handed chute can not self-locking; Top casing can be manipulated the water valve axle directly by vertex of a cone shape circular shaft and open and close current.

Hollow vertex of a cone shape circular shaft is pressed on the seal ring 24 of water valve axle hypomere upper top by spring 11 at ordinary times, make tap water can not enter the upper valve body pressure chamber thus, can only be from flowing through it, the aperture at hollow vertex of a cone circular shaft top being provided with the side of screw thread awl 13 and adjustment hole 23, and from then on the little cross-drilled hole 22 in circular shaft middle part slowly enters upper valve body pressure chamber 15 again.Treat that the upper valve body pressure chamber is full of water and forms and to promote piston behind the pressure and move down, the water valve that outer step arranged in the middle of driving axially under, make a plurality of horizontal perforation slot parts in its lower end enter osculum seal ring 5 and close current, water tap is in normally off.

During use, when shell 17 upwards or left-handed sliding the liter upwards, when driving the circular shaft vertex of a cone and making progress, the moment of its leaving water valve shaft hypomere upper top seal ring 24, the pressure water in the upper valve body pressure chamber rapidly from the water valve axle macropore 21 enter wherein and flow away downwards.This moment, the water valve axle was moved up by the spring pressure drive, and a plurality of hole slots that cross in its lower end pass the ascending unlatching current of osculum seal ring thereupon, and interior trepanning piston is also moved up by the interior negative pressure pulling of upper valve body pressure chamber, stops until reaching a certain height.Simultaneously current from vertex of a cone circular shaft top aperture 23 through the horizontal aperture 22 in side and middle part of screw threads awl meter adjustment holes, and hole 21 slowly enter in the upper valve body pressure chamber, be full of the back form pressure promote in the trepanning piston slowly downward, finally drive a plurality of hole slots that cross in the lower end of water valve axle and enter the osculum seal ring again and close current.Because of screw thread awl and adjustment hole flow are small and constant, selected the circular shaft distance that makes progress, selected water-outlet quantity exactly.

If the user thinks to close at once current, drive the water valve axle by shell by vertex of a cone circular shaft downwards and do not close current rapidly in pressure difference obstruction ground.Because the hypomere diameter is identical on the water valve axle, does not have pressure reduction, interior trepanning piston and water valve axle are again not have being slidingly connected of topping bar and hinder, thereby the time-delay closing piston mechanism does not influence manual operation.

In addition, sky 15 in the major diameter is established on upper valve body top, and the accumulation pressure water yield has increased delay time and water flow at double.

The friction of seal ring and smooth water valve axle is only arranged during operation is moved, and resistance is little, operates brisk; Displacement distance is less, and working life is corresponding longer.
