Description
Technical field
This utility model relates to the valve field of universal machine.
Background technology
Regulation valve is widely used in industrial fluid system, controls the flow velocity of all kinds of fluid, flow, pressure, pressure reduction etc., due to valve
Door inner chamber and throttling internals runner are complicated, change in flow great Yi when fluid passes through, gas medium such as steam, air, natural gas etc.
Compressible fluid spreads because of volume through throttling compression, expansion, easily forms noise.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that the high temperature resistant regulation of a kind of low noise
Valve, it is possible to decrease noise.
The purpose of this utility model is achieved in that the high temperature resistant regulation valve of a kind of low noise, including valve body, valve rod,
Valve seat, spool, sealing member, valve gap, arrange the medium flow channel being connected with body cavity on valve body and medium flows out logical
Road, valve seat, spool and sealing member be arranged in valve body, and the lower end of valve rod is connected with spool, and valve body, valve are stretched out in the upper end of valve rod
Lid is nested with on valve rod and is connected with valve body, and sealing member is arranged on the lower section of valve gap and between valve body and spool, sealing member,
Upper plenum is formed between valve gap, spool；Also setting up sleeve in described valve body, described spool is arranged in sleeve, under sleeve
End contacts setting with valve seat, and the upper end of sleeve contacts setting, arranges several throttling pore on sleeve, throttles little with sealing member
Hole is connected with medium flow pass.
The throttling pore that this utility model arranges rationally arrangement by valve sleeve outer surface limits flow velocity, prevents non-
Compression fluid falls below steam pressure for vaporization, and can reduce dashing forward due to compressible fluids such as such as steam, air, natural gass
The noise so expanded and produce reaches to reduce the purpose of noise.
Internals use the sleeve part with many regularly arranged through holes or the sleeve zero with many narrow parallel grooves
Part is as main noise reduction device.This structure, on the basis of not affecting valve negotiability, can effectively reduce fluid rapid
Stream, has obvious noise-reducing effect.It is mainly used in the occasion of high pressure difference gas or steam medium, is used for reducing medium at height
The huge noise produced during speed flowing.
Can also reduce what cavitation erosion produced with many regularly arranged ladder apertures outside sleeve part, this structure can
Effectively control rate of flow of fluid, it is to avoid the generation of cavitation, be substantially reduced control valve noise under harsh working condition, extend
The service life of control valve and replacement cycle.
Preferably, arranging lower cavity in the lower end of described spool, arrange balance aperture in the upper end of spool, balance aperture is even
Catharsis cavity and upper plenum.Realizing the upper plenum above spool and the pressure balance of cavity under spool, such spool is the most uneven
Weighing apparatus power is greatly reduced, and spool drives lighter.
Preferably, balanced seal circle is set between described spool and sleeve, it is ensured that sealing property.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As it is shown in figure 1, the high temperature resistant regulation valve of low noise, including valve body 1, valve rod 15, valve seat 3, spool 4, sleeve 5, close
Sealing 7, valve gap 11.
On valve body, 1 arranges the medium flow channel 2 and medium flow pass 10 being connected with body cavity, and medium flows into
Passage 2 is less than medium flow pass 10.
The lower end of valve rod 15 is arranged on valve body 1 inside and is connected with spool 4, and valve body 1 is stretched out in the upper end of valve rod 15.Valve gap 11
Being nested with on valve rod 15 and be connected with valve body 1, valve seat 3, sleeve 5, spool 4 and sealing member 7 are arranged in valve body 1, at valve gap
The lower section of 11 from top to bottom sets gradually sealing member 7, sleeve 5, valve seat 3, and the lower end of sleeve 5 contacts setting, sleeve 5 with valve seat 3
Upper end contact setting with sealing member 7, spool 4 is arranged in sleeve 5, arranges balanced seal circle 6 between spool 4 and sleeve 5.
Arranging several throttling pore 8 on sleeve 5, throttling pore 8 is connected with medium flow pass 10.
Sealing member 7 is between valve body 1 and spool 4, when spool 4 moves down, is formed between sealing member 7, valve gap 11, spool 4
Upper plenum 12, arranges lower cavity 13 in the lower end of spool 4, arranges balance aperture 9 in the upper end of spool 4, under balance aperture 9 connection
Cavity 13 and upper plenum 12.Upper plenum and the pressure balance of lower cavity, spool drives lighter.
Noise of the present utility model and flow-control are accomplished by:
Selecting to enter from right side for gas compressible fluid, (low in and high out) is flowed out in left side, enters valve on the right side of fluid
Body 1 cavity of resorption, is entered sleeve 5 inner chamber by valve seat 3, outside sleeve 5 distribution rule arrangement throttling pore 8, fluid when small holes,
Regularly through small holes combing, enter sleeve 5 outer space in order, owing to outer space is relatively big, after diverging expansion, dredged
Diffusing goes out valve body.It is to consider effusion meter control characteristic requirement that aperture is arranged, and controls both sides pressure reduction, make outlet pressure during aperture design
Higher than pressure for vaporization, reduce cavitation phenomenons.Spool 4 connects as one with valve rod 15, is driven by driving means, it is achieved live up and down
Dynamic, when spool 4 moves, valve opening increases, and flow becomes big；When moving down, flow reduces.
