Accompanying drawing explanation
Fig. 1 is cross-sectional view of the present utility model.
Detailed description of the invention
With specific embodiment, this utility model is further described below in conjunction with the accompanying drawings, sees Fig. 1:
A kind of micro-hydraulic pressure pressure-stabilizing pressure regulation valve, including valve body 1, is provided with the intake tunnel 2 being interconnected and leads to water outlet in valve body 1
Road 3, the downside of valve body 1 connects valve gap 4, is provided with valve seat and valve rod 5 between intake tunnel 2 and exhalant canal 3, valve rod 5 upper
End is provided with the spool of closure valve seat, and the lower end of valve rod 5 is run through valve body 1 and extend into valve gap 4 intracavity and be set with epithelium 6 and epithelium pressure
Plate 7, valve cover cavity is divided into the pressure chamber 8 of inner side, the atmospheric chamber 16 in outside by epithelium 6, and exhalant canal 3 and pressure chamber 8 are by logical
Water channel 9 connects, and atmospheric chamber 16 connects air, is provided with the spring 10 that one end withstands on epithelium pressing plate 7 in atmospheric chamber 16.
The concrete structure of above-mentioned spool is: the upper end of valve rod 5 is set with the sealing ring 11 with valve seat fitted seal, sealing ring
11 cartridge cover 12 being threadedly attached on valve rod 5 compress.
The lower end of above-mentioned valve gap 4 is provided with opening, and opening is bolted with spring capping 13, and spring capping 13 is provided with and normal pressure
The through hole 14 that room 16 is connected, one end apical grafting of described spring 10 on epithelium pressing plate 7, other end apical grafting is at spring capping 13
On.
The position that above-mentioned valve rod 5 runs through valve body 1 is provided with annular groove, is set with sealing ring 17 in annular groove, seals
Circle 17 can guarantee that, when valve rod 5 slides up and down work, intake tunnel 2 does not connects with pressure chamber 8, it is achieved intake tunnel 2 and pressure chamber 8
Isolation.
Valve body 1 above above-mentioned spool is provided with opening, and threaded on opening have sealing lid 15.
Above-mentioned epithelium 6 is made up of elastomeric material, and the formation annular protrusion that upwards arches upward near the position of outer edge on epithelium
20, the epithelium 6 of this structure is conducive to crossing hightension when alleviating epithelium work.
The lateral wall of the above-mentioned valve body 1 being positioned at exhalant canal 3 side is provided with Hall element 18, is provided with in exhalant canal
Rotating and have magnetic impeller 19, on a toroidal support, ring support is sleeved on water outlet to the rotating installation of impeller 19
In passage 3, in the course of the work, water jet propulsion impeller 19 rotates valve, and impeller 19 forms the magnetic field of change and then touches after rotating
Send out Hall element 18, the size of discharge can be calculated by calculating the pulse signal of Hall element 18.
Operation principle of the present utility model is:
Water enters in the intake tunnel 2 of valve body from the water inlet of valve body 1, under normal circumstances the spool in valve body 1 and valve
Seat is in open mode, there is water space between spool and valve seat, and the water in intake tunnel 2 enters into valve by crossing water space
The exhalant canal 3 of body 1, then flow out to solar water heater liner water supply from the outlet of valve body 1；
To in solar water heater liner or automatic constant temperature water heater water supply process, the hydraulic pressure in entering into valve body 1
Time higher, enter into the water in exhalant canal 3 by water space excessively and enter in pressure chamber 8 by waterway 9 again, pressure chamber 8
The pressure of interior water acts on and makes epithelium 6 form downward tension force on epithelium 6, and the downward tension force of epithelium 6 overcomes the effect of spring 10
Power and then compression spring 10 pull epithelium pressing plate 7 to move downwardly together with valve rod 5, and the water space of crossing between spool and valve seat contracts
Little；
When the hydraulic pressure entered in valve body 1 is relatively low, the water in exhalant canal 3 enters into pressure chamber 8 by waterway 9
In, in pressure chamber 8, the pressure of water acts on and pulls epithelium 6 to form downward tension force on epithelium 6, and now the active force of spring 10 is big
In the tension force that epithelium 6 is downward, the effect hypodermis mould plate 7 at spring 10 moves upwardly together with valve rod 5, between spool and valve seat
Cross water space expand；
Water space of crossing between spool and valve seat realizes dynamically regulation with the change of hydraulic pressure, and no matter the size of hydraulic pressure all can be protected
The card pressure stability of pressure regulator valve water outlet and stablizing of discharge, it is also possible to regulate spring 10 by rotating spring gland 13
Compression degree, comes output hydraulic pressure and the output flow of control valve by changing spring 10 to the active force of epithelium pressing plate 7.
When solar water heater or automatic constant temperature water heater are without water, when complete machine is closed, in exhalant canal 3
Water enters in pressure chamber 8 by waterway 9, and in pressure chamber 8, the pressure of water acts on and makes epithelium form downward opening on epithelium 6
Power, the downward tension force of epithelium 6 overcomes the active force of spring 10 and then compression spring 10 to make epithelium pressing plate 7 with valve rod 5 downwardly together
Mobile, spool is fitted with valve seat, and the water of intake tunnel 2 cannot propagate in exhalant canal 3, thus at solar water heater or
When automatic constant temperature water heater does not uses, in the hydraulic pressure of tap water also will not be transmitted to the inner bag of solar water heater or automatic constant-temperature
In the inner bag of water heater, thoroughly separate external pressure.
Above-described embodiment is only preferred embodiment of the present utility model, limits protection model of the present utility model the most according to this
Enclose, therefore: all equivalence changes done according to structure of the present utility model, shape, principle, protection of the present utility model all should be covered by
Within the scope of.
