Detailed description of the invention
As shown in Figure 1, Figure 2 and Figure 3: high accuracy quickly response low noise pressure-regulating valve, it includes bearing 4, leading screw rear support 13, valve cage 9, chute 6, feed screw nut 7, slide block 8, orifice plate 11, orifice plate drive end bearing bracket 10, orifice plate rear end cap 12 before valve body 1, guide shell 3, water conservancy diversion support plate 14, leading screw 5, leading screw；Described guide shell 3 is fixed in valve body 1 by water conservancy diversion support plate 14, and guide shell 3 port of export is connected with orifice plate drive end bearing bracket 10, and orifice plate rear end cap 12 is connected with valve body 1, and orifice plate 11 is installed between orifice plate front and rear cover 10,12；Leading screw 5 one end is fixed in guide shell 3 by bearing 4 before leading screw, and the other end is fixed on valve body 1 by screw mandrel rear support 13, and wherein one end connects driving means 2；Feed screw nut 7 is connected with valve cage 9, valve cage 9 has slide block 8, slide block 8 are limited in chute 6 and slides axially.
Valve body 1 can be overall processing, it is possible to by Flange joint or welding after segmental machining, and valve outer surface can arrange gusset increases body strength, and valve body 1 is placed on support 15.Form circular passage between guide shell 3 and valve body 1 and guide air current flow.Water conservancy diversion support plate 14 arranges 4, and downstream direction is installed, and is evenly arranged vertically.Orifice plate drive end bearing bracket 10 is connected with guide shell 3 end, and the cooperation face that contacts with each other arranges sealing, prevents high pressure draught leakage before valve.Orifice plate rear end cap 12 is connected with valve body 1 port of export, and the cooperation face that contacts with each other needs to arrange sealing, prevents high pressure draught leakage before valve.Orifice plate 11 is annular, is installed between orifice plate drive end bearing bracket 10 and orifice plate rear end cap 12, detachably.The number of plies of orifice plate 11 is not limited to shown in figure 3 layers, can require the increase and decrease orifice plate number of plies according to range of regulation and noise reduction capability.Last layer of orifice plate breathing area that air-flow passes through is to be realized by moving axially of valve cage 9.Being welded with slide block 8 on valve cage 9, slide block 8 is limited in chute 6 and slides axially.
Actuator is driven mainly to be made up of leading screw 5, feed screw nut 7.Leading screw 5 is fixed by bearing before screw mandrel 4 and screw mandrel rear support 13, and feed screw nut is connected with valve cage 9 bolt or welds, and drive system 2 drives leading screw 5 to rotate, and the convert rotational motion of screw mandrel 5 is linear motion by feed screw nut 7, drives valve cage 9 slide anteroposterior.
As shown in Figure 2: the low noise pressure-regulating valve of the present invention when semi-open state, air current flow as shown by arrows in FIG., by the circular passage between valve body 1 and guide shell 3 flow into multilamellar orifice plate 11 region.Air-flow pressure after each layer of orifice plate can reduce, and flows through last layer of orifice plate, flows out valve after reaching required downstream pressure.When valve cage 9 is in maximum travel position, air-flow is cut off.
The present invention is during pressure regulation, owing to have employed the mode that multilamellar orifice plate classification blood pressure lowering and micropore jet are eliminated the noise, it is to avoid shock wave noise, jet noise under high pressure ratio, avoids the generation of very noisy from source.Meanwhile, this structural shape makes valve cage can quickly move and be accurately positioned, it is possible to meet the requirement of intermittent wind tunnel rapid pressure regulation.
It is more than the preferred forms of the present invention, the content announced according to the present invention, can easily draw other concrete schemes.
