Description
Technical field
The present invention relates to a kind of water saving fixtures, relate in particular to a kind of water flow and stablize effective water-saving water saving fixtures with water economizer.
Background technique
The employed time-delay valve of water saving fixtures in the past, it mostly is perforate on buoyancy aid, on the hole, cover filter screen then, water enters the time-delay chamber by filter screen from the hole on the buoyancy aid, time has been grown filter screen and has been stopped up by the foreign material in the water easily, the water level that water can not enter the water of delaying time the chamber or entering is not enough, does not have the effect that reliable and stable time-delay control discharges water; Also have plenty of in addition on the main body inner wall of the cooperation place of main body and buoyancy aid and have gutter, such gutter is not easy to be stopped up by foreign material, the water inlet of time-delay chamber smoothly, but because gutter leaves on main body inner wall, processing is big, the cost of production height.
At present, have time-delay and wash, close automatically the valve series products of using with the flushing device for toilet of flow control function, a function with manual control flow rate.Flow was too small when hydraulic pressure was low when bath, and just effect is dashed in influence; Flow was excessive when hydraulic pressure was high, the serious waste water resources.And hand control valve is because its most volume is bigger than normal, and complex structure is unfavorable for the control of product cost.
Have and see and this, the applicant's independent research a kind of water-outlet quantity that can guarantee stable, and guarantee effectively using water wisely under the developing result prerequisite.
Summary of the invention
Technical problem to be solved by this invention is the defective that overcomes prior art, provides a kind of and can stablize water flow, guarantees effective water-saving water saving fixtures under the developing result prerequisite.
The technical solution adopted for the present invention to solve the technical problems is: a kind of water saving fixtures with water economizer, comprise a stainless steel adapting piece, stainless steel adapting piece is provided with into, and the water nut makes intake pipe fixedly be communicated with stainless steel adapting piece, the stainless steel adapting piece below is connected with outlet pipe and installs and fixes with the water outlet nut, stainless steel adapting piece is provided with foot-operated, be provided with in the stainless steel adapting piece by the foot-operated time-delay valve that opens or closes that triggers, one water economizer is installed in the feed-water end of outlet pipe, water economizer comprises a water saving shell, water saving shell upper inboard is provided with the hard-wired piston gland of screw thread, and piston gland is that hollow structure forms intake tunnel; Be provided with the tapered piston that is positioned at the piston gland below in the water saving shell, leave the space between tapered piston and the water saving shell and form split channel, tapered piston also forms water channel for hollow structure, and intake tunnel and exhalant canal communicate; Water saving outer casing underpart inboard is protruding with a boss, and the tapered piston upper outside also is protruding with a boss, and the outside of tapered piston is with the pressure spring between water saving shell boss and tapered piston boss, and two boss are spacing as pressure spring; Tapered piston is provided with open communication exhalant canal and split channel, and the tapered end face maximum diameter of tapered piston is equal to or greater than the sealing end face diameter of water saving shell waterexit end, and other diameters of tapered end face are less than the sealing end face diameter of water saving shell waterexit end; Also be provided with first seal ring between tapered piston top and the water saving shell, the water saving shell outside is with second seal ring of realizing sealing with outlet pipe.
As the further design to the aforementioned techniques scheme: aforesaid water saving shell upper is outward extended with and the annular boss of outlet pipe as limit mounting.
The basic principle of operation of water economizer is: be in when closing at water economizer, pressure spring is not compressed, and tapered piston is in initial static, and this moment, split channel was crossed water cross section maximum, and crosses the water cross section greater than exhalant canal; When water economizer is opened, when pressure of supply water during less than minimum operationg pressure differential, tapered piston 2 is in initial static, and a part of water flow flows out from split channel, another part water flow flows out from exhalant canal, and water flow is split channel and exhalant canal flow sum; When pressure of supply water during greater than minimum operationg pressure differential, tapered Piston Compression spring, piston moves to the waterexit end, split channel must be crossed the water cross section and reduce with the pressure reduction increase, corresponding water flow reduces, the water flow of exhalant canal then increases and increases in a small amount with pressure reduction, but the water flow sum of split channel and exhalant canal still remains unchanged; When pressure of supply water during greater than maximum operating pressure differential, split channel is closed, and water flow is all flowed out by exhalant canal.
In sum, water saving fixtures of the present invention are compared with water saving fixtures of the prior art and are had following advantage:
One, simple in structure, the big parts of whole water economizer are made up of water saving shell and tapered piston substantially;
Two, water flow is stable, no matter hydraulic pressure what, its water flow is all quantitative, water flow is not affected;
Three, using water wisely, because its water flow is stable, water flow can be not too much, saved water effectively under the prerequisite that guarantees developing result;
Four, volume is little, and is easy for installation, and water economizer directly is installed in the outlet pipe, need not outlet pipe is changed, and directly installation just can;
Five, sturdy and durable, water economizer is full copper valve body, has the piston and the stainless copper pressure spring of sealed type, detects sensitivity, and work is balanced during use.
