Description

Energy-saving water tap

The utility model relates to the terminal part in a kind of water system, particularly a kind of energy-saving water tap, and it belongs to the valve class.

Water nozzle of the prior art (being commonly called as water tap) is knob type mostly, and it opens or closes water nozzle by rotation hand wheel, and the frictional resistance that the water nozzle Sealing of this structure is born is big, wearing and tearing easily, leak easily with of a specified duration, working life is shorter, and maintenance load is big simultaneously.China Patent No. 92242157.9 discloses the utility model patent structure that a kind of name is called " magnetic control revolves control water nozzle ", it is by matrix, adjusting knob, anti-pivoted housing, composition such as magnet ring and small plunger, its keying is to realize by the magnetic force of magnet ring and magnetic post, move on the magnet ring, the pulling force that makes progress that acts on the magnetic post just increases gradually, up to pulling force during greater than the pressure of water, the magnetic post just moves in the meeting, aperture on the small plunger is just opened at this moment, water flows out from aperture, and the hydraulic pressure that acts on the magnetic post reduces to zero suddenly, and the magnetic post is gone up suddenly and jumped, small plunger and big piston are also and then gone up and are jumped, and valve open is to maximum; Although the water nozzle of this structure has been broken the principle of traditional water nozzle forced seal, designed the structure of water pressure self-closing, in actual use, it still exists the current size can't regulate this fatal weakness.

The purpose of this utility model is to overcome above shortcomings of the prior art, and a kind of reasonable in design, the big I regulated at will of current and energy-saving water tap easy to use and reliable, that the life-span is long are provided.

The purpose that the utility model proposed can be achieved through the following technical solutions: this energy-saving water tap comprises that matrix, carrying handle, carrying handle cover, open and close plug, open and close and fill in connecting rod, piston, the middle aperture of piston and seal ring, its structural feature is to open and close between plug and the valve rod retainer ring and between valve rod retainer ring and the carrying handle all to glued joint by viscose glue, design has oval conehead in the piston bottom, and is provided with buffer ring above water outlet.

Buffer ring of the present utility model is a conical bowl bodies, is distributed with several sulculuses on its cylndrical surface equably, makes vertical dirty water by the soft water outlet that stably flows out of the effect of buffer ring, and the phenomenon of having avoided direct projection to splash produces.

The utility model also is provided with the technology circle, and this technology circle is arranged on and opens and closes on the plug connecting rod, plays and block the dirty effect of viscose glue in assembly process.

Description of drawings is as follows:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a buffer ring structural representation of the present utility model.

Fig. 3 is the A-A sectional view of the utility model buffer ring.

Following the utility model will be in conjunction with the accompanying drawings, and be described in further detail by embodiment.

Referring to Fig. 1, the utility model mainly is made up of matrix 11, carrying handle 6, keying plug 7, keying plug connecting rod 17, piston 12 and buffer ring 15 etc., matrix 11 is skeletons of whole water nozzle, connects piston sleeve 8 on it, connects water outlet 16 down, and side then links to each other with water inlet tap 19; Open and close plug connecting rod 17 and fuse by pressure injection, wherein open and close plug 7 usefulness plastics and make, open and close plug connecting rod 17 and then make, thereby the intensity at this key abrasion position is improved greatly, prolonged working life with Stainless Steel Wire with opening and closing plug 7; Open and close between plug connecting rod 17 and the valve rod retainer ring 2, all adopt viscose glue 20 splicing between valve rod retainer ring 2 and the carrying handle 6, make connection more firm, reliably; Piston 12 is positioned at the below that opens and closes plug 7, and the design of piston 12 bottoms has oval conehead 12-1, and the size of current is regulated, and also designing on the piston 12 has the middle aperture 18 of piston, is convenient to the open-minded of water nozzle during use; Above water outlet 16, be provided with buffer ring 15, seem very soft stable after making vertical dirty water by buffer ring 15, can not produce the phenomenon that direct projection is splashed.

During use, because glueing joint by viscose glue 20, carrying handle 6, carrying handle lid 1, valve rod retainer ring 2, keying plug connecting rod 17 fuse, so when carrying handle 6 presses down, opening and closing plug connecting rod 17 together moves down together with opening and closing plug 7, open and close plug 7 heads and withstand the piston packing 10 on piston 12 tops, making alive cold 12 to move down, withstanding the seal washer 13 that is contained on the water outlet 16 up to the wedge angle 12-2 at piston 12 middle parts circumference, this moment, water nozzle was cut off the water supply; Because between piston 12 and piston sleeve 8, keying plug 7 and the piston sleeve 8 is gapped, Gu Shui is full of piston sleeve 8 volume inside by the gap, and hydraulic pressure acts on piston 12 all the time and opens and closes on the plug 7, so can accomplish watertight.When carrying handle 6 is up mentioned, open and close plug 7 and and then up move, aperture 18 is open-minded in the middle of the piston on piston 12 tops, the water on piston 12 tops flows out the aperture 18 in the middle of piston, upper pressure reduces suddenly, and piston 12 disequilibriums are upwards floated, this moment, water nozzle was open-minded, owing to the oval conehead 12-1 of piston 12 bottoms, the distance that piston 12 is moved up is big more simultaneously, and the area of water outlet is big more, current are also just big more, realized that thus the power of current sizes is just regulated.The effect of regulating nut 4 is to compress seal ring 5, makes the bottom surface of seal ring 5 tightly touch the last plane of piston sleeve 8, thereby plays the effect of sealing; Technology circle 3 plays and block the dirty effect of viscose glue 20 in assembly process; Last seal ring 9 and lower seal 14 seal between link.

Referring to Fig. 2, Fig. 3, this buffer ring 15 is bowl bodies of a cylinder type, the sulculus 21 of distributed equably on its cylndrical surface 16 (0.8 mm wide, 4.5 millimeters long); Three 90 ° big curved outflow from sulculus 21 has been changeed in the bottom that vertical dirty water is flushed to buffer ring 15, turn over one 90 ° big curved just outflow from water outlet 16 (referring to Fig. 1) again, owing to bending of one 90 ° of revolutions, water velocity all will slow down a lot, so will be very soft stable by the water that flow out four curved backs, can direct projection not splash.

The utility model has the following advantages compared with prior art: 1, reasonable in design, simple; Owing in the piston bottom oval conehead is arranged, the size of current is regulated easily, and open and close brisk, joint Can; 2, good seal performance, long service life: since open and close plug connecting rod, valve rod retainer plate and carrying handle it Between adopt to glued joint, so its connection is more reliable, good seal performance, simultaneously, make the intensity at key abrasion position Improve, prolonged service life; 3, it is soft stable to go out water speed: owing to be designed with bumper ring, make vertical Dirty water velocity slows down, and can not produce phenomenon and good energy-conserving effect that direct projection is splashed; Fill when 4, designing Divide and consider and firm, the reliable connectivity problem of the water inlet pipes such as washing machine, dish-washing machine.
