Description
Technical field
The utility model relates to valve technology field, and especially a kind of outlet pressure that makes valve is lower than the fluid pressure valve of inlet pressure.
Background technique
Reduction valve is a kind of special arrangement of automatic reduction working pressure of pipeline; It can be reduced to the required level of pipeline behind the valve with pipeline higher hydraulic pressure before the valve; Reduction valve is widely used in tall building, too high zone, mine and other occasions of city water-supply pipe network hydraulic pressure, and each obtains suitable service hydraulic pressure and flow with water spot in the water system to ensure to.Traditional reduction valve comprises the valve body with water intake and water outlet; Also has a valve core case in the valve body; Be provided with a flap assembly in the valve body; Be provided with a spool in the valve core case, the flap assembly can move up and down along spool under the effect of a pressure regulation assembly, forms a water channel of crossing that when the flap assembly moves up and down, can change water flux density between flap assembly and the spool.But this kind reduction valve is prone to the flap assembly is depressed into the spool lowermost end when the hydraulic pressure of water intake is excessive, makes that the effect of easing stress of reduction valve is unstable and decompressor whole reduction valve is fragile, and then makes reduction valve weak effect, life-span low.
Summary of the invention
Therefore, to above-mentioned problem, the utility model proposes that a kind of effect of easing stress is stable, the novel reduction valve of long service life.
For realizing above-mentioned purpose, the utility model has adopted following technological scheme: a kind of novel reduction valve comprises valve body; Valve body is provided with horizontal intake tunnel and exhalant canal, also is provided with vertical current control channel on the said valve body, is provided with current control mouthful a connection intake tunnel and an exhalant canal in the middle of this current control channel; Vertical current control channel top is provided with bonnet, and the bottom is provided with lower end cap, and current control channel is provided with spool mechanism; Said spool mechanism comprise valve rod and be fixedly arranged on bonnet and valve body between diaphragm, the upper end of said valve rod is fixedly arranged on the diaphragm, the lower end of this valve rod is provided with flap and flap sealing seat; Said bonnet is provided with adjusting screw rod; This adjusting screw rod is provided with spring pressuring plate, is provided with upper spring between said spring pressuring plate and the diaphragm, is provided with lower spring between said lower end cap and the flap sealing seat.
Through adopting the aforementioned techniques scheme; The beneficial effect of the utility model is: through between the lower end cap of reduction valve and flap sealing seat, setting up a lower spring; Make the lower end of whole reduction valve flap assembly when the hydraulic pressure of water intake is excessive that the auxiliary hydraulic pressure of alleviating of lower spring arranged; Be difficult for the flap assembly is depressed into the spool lowermost end, make that the effect of easing stress decompressor stable and whole reduction valve of reduction valve is not fragile, and then make that reduction valve is effective, the life-span is long.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation.
Embodiment
Combine accompanying drawing and embodiment that the utility model is further specified at present.
Consult shown in Figure 1ly, a kind of novel reduction valve of the utility model comprises valve body 1; Valve body 1 is provided with horizontal intake tunnel 11 and exhalant canal 12, also is provided with vertical current control channel on the said valve body 1, is provided with a current control mouthful 13 connection intake tunnels 11 and exhalant canal 12 in the middle of this current control channel; Vertical current control channel top is provided with bonnet 2, and the bottom is provided with lower end cap 3, and current control channel is provided with spool mechanism 4; Said spool mechanism 4 comprise valve rod 41 and be fixedly arranged on bonnet 2 and valve body 1 between diaphragm 42; The upper end of said valve rod 41 is fixedly arranged on the diaphragm 42, and the lower end of this valve rod 41 is provided with flap 411 and flap sealing seat 412, said valve rod 41 with up and down movably mode be contained in the vertical current control channel; Flap sealing seat 412 can be blocked current control mouth 13 when valve rod 41 moved up; Current control mouthful 13 apertures that are communicated with intake tunnel 11 and exhalant canal 12 are strengthened, and said bonnet 2 is provided with adjusting screw rod 21, and this adjusting screw rod 21 is provided with spring pressuring plate 211; Be provided with upper spring 5 between said spring pressuring plate 211 and the diaphragm 42; Can be during use through the moving up and down of adjusting screw rod 21 ACTIVE CONTROL valve rods 41, thus the size of current control mouthful aperture regulated, be provided with lower spring 6 between said lower end cap 3 and the flap sealing seat 412; Hydraulic pressure through lower spring 6 can make flap sealing seat 412 bear water intake is shared, and guarantees the stable of effect of easing stress.
The utility model is through setting up a lower spring between the lower end cap of reduction valve and flap sealing seat; Make the lower end of whole reduction valve flap assembly when the hydraulic pressure of water intake is excessive that the auxiliary hydraulic pressure of alleviating of lower spring arranged; Be difficult for the flap assembly is depressed into the spool lowermost end; Make that the effect of easing stress decompressor stable and whole reduction valve of reduction valve is not fragile, and then make that reduction valve is effective, the life-span is long.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; But the those skilled in the art should be understood that; In the spirit and scope of the utility model that does not break away from appended claims and limited; Can make various variations to the utility model in form with on the details, be the protection domain of the utility model.
