Constant current valve seat 4 hollows, the direction of the endoporus of constant current valve seat 4 from the feed-water end to the waterexit end is provided with successively cone shape hole 41, supporting frame 42, regulates chamber 43; Described cone shape hole 41 is negative and positive with the outer wall of modulating valve 3 and coordinates; The direction of the outer wall of constant current valve seat 4 from the feed-water end to the waterexit end is divided into two parts of joining, and the direction from the feed-water end to the waterexit end is followed successively by location bead 44 and mixing chamber 45; The diameter of described location bead 44 is greater than the diameter of mixing chamber; Be provided with a circle pore 46 on the wall of mixing chamber 45; Be provided with screw thread on the wall of regulating chamber 43.
Pressure release valve seat 5 is provided with central through bore, and its waterexit end endoporus is negative and positive with the outer wall construction of Decompression valves 6 and coordinates; The valve rod of Decompression valves 6 is provided with endoporus, is provided with screw thread on inner hole wall; Regulation spring 7 consists of column spring and turriform spring serial connection, and the column spring is positioned at feed-water end, and the tower top diameter of turriform spring is identical with the column spring; Jet orifice plate 8 is provided with intensive spray orifice.
Described shell 9 is for being provided with the Cylindrical object of central through bore, and the direction of its endoporus from the feed-water end to the waterexit end is divided into two sections, and the diameter of first paragraph is greater than the diameter of second segment, and the diameter of second segment is greater than the external diameter 0.4mm-1.4mm of constant current valve seat 4 waterexit ends.
Regulating ring 11 is the tubulose of hollow, end face towards feed-water end is provided with three above adjustable columns 111, the regulating ring outer rim is provided with outside thread, and the edge of regulating ring waterexit end is provided with the adjusting bead of a circle projection, and the diameter of described adjusting bead is more than or equal to the diameter of shell 9.
During assembling, modulating valve 3 is filled in to the cone shape hole 41 of constant current valve seat 4, make the center hole of the newel 32 of modulating valve 3 through supporting frame 42, then pressure release valve seat 5 is filled in to constant current valve seat 4 from waterexit end to the direction of feed-water end, its inner hole sleeve is connected on the newel 32 of modulating valve 3; Decompression valves 6 inserts its endoporus from the waterexit end of pressure release valve seat 5, and passes the support 33 of modulating valve 3; Pressure release spring 2 is filled in to its central through bore from the feed-water end of modulating valve 3, then the direction from feed-water end to waterexit end, through pressure release spring 2, is screwed in the endoporus of Decompression valves 6 valve rods screw 1; The column spring section of Regulation spring 7 is filled in to it regulates chamber 43 and is screwed in the outer wall thread of pressure release valve seat 5 from the waterexit end of constant current valve seat 4; Jet orifice plate 8 is put into to it from the waterexit end of constant current valve seat 4 and regulated chamber 43; Again constant current valve seat 4 is filled in to its inner chamber from the feed-water end of shell 9, filter screen 10 is put into to the inner chamber of regulating ring 11 from feed-water end, then regulating ring 11 is filled in and is screwed in the inner thread of mixing chamber from the waterexit end of shell 9; In the process screwed, the adjustable column 111 on regulating ring 11 withstands on jet orifice plate 8.
When regulating ring 11 is screwed on constant current valve seat 4 fully, pore 46 is between the water inlet end face and jet orifice plate 8 of regulating ring 11.
Before use, seal ring is filled in to its endoporus from the feed-water end of shell 9, be pressed onto the feed-water end edge of constant current valve seat 4, then be screwed on the tap water outlet mouth.
During work, open tap, water enters into leading constant current water outlet, the water inlet end face of water impact modulating valve, pressure-acting due to Regulation spring 7, modulating valve 3 is in open mode, current flow into from the gap between modulating valve and constant current valve seat regulates chamber 43, be ejected into mixing chamber through the hole on jet orifice plate 8, according to venturi principle, swiftly flowing water makes in mixing chamber to produce negative pressure, extraneous air enters in mixing chamber along the gap of leaving between regulating ring and shell, water and air strikes on filter screen, damping function due to filter screen, the water sprayed slow down and, being mingled with air flows out.
When the hydraulic pressure of the modulating valve 3 of flowing through larger, while being enough to overcome the prestressing force of Regulation spring 7, gap between modulating valve and constant current valve seat will be just little, the water yield that flows through leading constant current water outlet will reduce, as now hydraulic pressure minimizing, under the effect of Regulation spring, the gap between modulating valve and constant current valve seat can become again greatly, thereby plays the constant current effect of current stabilization flow control.If flow through, the hydraulic pressure of modulating valve is large especially, the prestressing force that surpasses Regulation spring, at this moment, gap between modulating valve and constant current valve seat is blocked fully, powerful hydraulic pressure will promote Decompression valves 6 by the central through bore of modulating valve, Decompression valves overcomes the pressure of pressure release spring, and the space between Decompression valves and pressure release valve seat is opened, and current just flow into the adjusting chamber from the central through bore of modulating valve.So just can prevent from the cutout phenomenon occurring when hydraulic pressure is especially big, and guarantee suitable water-outlet quantity.
In actual use, the user can, according to the actual demand of self, by regulating regulating ring in the position of the mixing chamber of constant current valve seat, control max water yield.Regulating ring is twisted toward the direction of feed-water end, and adjustable column is toward the direction top spray orifice plate of feed-water end, and jet orifice plate is pressed Regulation spring to the direction of feed-water end, makes the prestressing force of Regulation spring strengthen, thereby strengthens water-outlet quantity.Otherwise will reduce water-outlet quantity.
Tap constant current water outlet can not produce harmful effect to current when hydraulic pressure is low, only has when hydraulic pressure is excessive, just plays a role, and like this, has both played the effect of constant current, does not affect again user's normal use.
Directly substitute traditional tap water outlet mouth with leading constant current water outlet, modulating valve can be regulated its position in cone shape hole automatically according to the variation of hydraulic pressure, if hydraulic pressure is excessive, modulating valve has sealed cone shape hole, the position of adjusting pressure release valve in modulating valve, thus reach the purpose of stablizing water-outlet quantity; Spray head at the prestressing force of regulating Nei position, chamber adjustment Regulation spring by adjustment, play the purpose of water yield adjusting as required.
The prestressing force of adjusting Regulation spring by adjusting regulating ring plays the purpose of water yield adjusting as required, and in exiting water process, utilizes the pore be located on the constant current valve seat that extraneous air is mixed with water, produces soft current.
The utility model can also promote the use of liquid and the gas field that needs to control flow.
Above-described embodiment is only for interpretation purposes of the present utility model; and be not to restriction of the present utility model, those skilled in the art, in essential scope of the present utility model; make a variety of changes or substitute, also should belong to protection category of the present utility model.
