Description
Technical field
The utility model relates to a kind of modulating valve, particularly a kind of High Pressure Difference flow control valve.
Background technique
Prior art adopts multi-stage sleeve decompression, perforate on sleeve.Under large pressure reduction condition, high-pressure liquid flows to after valve body, by the multi-stage porous on sleeve, carry out multi-step pressure reduction, thereby reduction flow velocity, but because sleeve is to be horizontally set on valve core inside, and put into practice bottom upper valve body, be only and be subject to pressure reduction maximum, the impact force being subject to is maximum, therefore utilize sleeve decompression decompression efficiency low, poor effect.
Model utility content
In order to overcome the inefficient deficiency of decompression, the utility model provides a kind of High Pressure Difference flow control valve.
The technological scheme that the utility model adopts is: a kind of High Pressure Difference flow control valve, it comprises and is provided with influent stream mouth and goes out the valve body of head piece, the mangetic core assembly that is positioned at valve body and decompressor, described decompressor comprises the circumferentially aperture portion of perforate of bottom, top and surface, this bottom inlay card is in valve body, top and mangetic core assembly lower end surface offset, the cavity in influent stream mouth, decompressor, mangetic core assembly and go out head piece and form circulation passage.
Also comprise that level is placed in the sleeve in mangetic core assembly, described sleeve has window towards the one side of decompressor, the cavity in described mangetic core assembly by sleeve with go out head piece and be communicated with.
Described decompressor is cylindrical body.
Described aperture portion has many rounds.
With row's described hole, aperture is identical; Different rows' described hole, aperture increases successively from top to bottom.
With row's described hole, circumferential array distributes.
The beneficial effects of the utility model are: this High Pressure Difference flow control valve increases decompressor, and have many rounds in decompressor aperture portion peripheral surface, aperture increases successively from top to bottom, convection cell disperses and to keep maximum capacity, passes through fluid uniformly simultaneously, pressure is consumed at this, thereby directly avoided fluid to improve the working life of sleeve and valve the impact of valve body, spool and sleeve.

Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
As shown in Figure 2 and Figure 3, a kind of High Pressure Difference flow control valve, it comprises and is provided with influent stream mouth 11 and goes out the valve body 1 of head piece 12, the mangetic core assembly 2 that is positioned at valve body 1 and decompressor 3, described decompressor 3 comprises the circumferentially aperture portion 33 of perforate of bottom 31, top 32 and surface, these bottom 31 inlay cards are in valve body 1, top 32 offsets with mangetic core assembly 2 lower end surfaces, also comprises that level is placed in the sleeve 4 in mangetic core assembly 2, and described sleeve 4 has window 41 towards the one side of decompressor 3.Cavity 21 in influent stream mouth 11, decompressor 3, mangetic core assembly 2 and go out head piece 12 and form circulation passages, the cavity 21 in described mangetic core assembly 2 by sleeve 4 with go out head piece 12 and be communicated with, can increase mangetic core assembly 2 and go out the sealing between head piece 12.
As shown in Figure 1 and Figure 2, High Pressure Difference flow control valve, its influent stream mouth 11, fluid is from high to low, go out head piece 12, fluid from low to high, thereby the regulating action of realization, but there is height on earth, the potential energy of fluid can turn to kinetic energy, thereby produce, act on valve body 1 inside and spool, impact force on sleeve 4, especially at the first cavity 51, pressure reduction is maximum, the impact force being subject to is maximum, now at the interior increase decompressor 3 of the first cavity 51, the hole that utilizes decompressor 3 aperture portion 33 peripheral surface to have, convection cell disperses and is even, pressure is consumed at this, directly avoided the impact of fluid to valve body 1, fluid flows to the second cavity 52 through hole from influent stream mouth 11, the 3rd cavity 53, cushion, spool and sleeve 4 are played a very good protection, last fluid flows to out head piece 12 from the 4th cavity 54, this is that pressure reduction is little, the wearing and tearing of sleeve 4 are just little, working life that so can lengthening sleeve 4, improve the working life of valve body 1 simultaneously.
As shown in Fig. 3, Fig. 4, Fig. 5, described decompressor 3 is cylindrical body, the shape that cylindrical body has corner angle with respect to other, wear resistance is better, stands the permanent impact of fluid, the aperture portion 33 of decompressor 3 has many rounds, to keep maximum capacity by fluid, with row's described hole circumferential array distribution, cylindrical installation like this is aimed at without special angle, with row's described hole, aperture is identical; Different rows' described hole, aperture increases successively from top to bottom, make the aperture portion of decompressor 3 all inevitable porose on circumferential 360 ° of curved surfaces, even decompressor 3 is owing to being subject to fluid impact to have trace rotation in using process like this, also inevitable porose over against influent stream mouth 11, and because fluid exists potential difference, so the impulse force that decompressor 3 is subject to compared with near hole apart from bottom 31 can be larger than the impulse force of receiving compared with near hole apart from top 32, so different rows' described holes, increase successively can uniform stressed in aperture from top to bottom.
Below described embodiment is only preferred implementation of the present utility model by reference to the accompanying drawings, and the not restriction to protection domain of the present utility model, any improvement of doing based on the utility model spirit all ought to be within the utility model protection domain.
