Fig. 2 is the sectional view at A-A place among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing scheme of the present utility model is further specified.
Sylphon seal sleeve adjusting valve as shown in Figure 1, comprise bonnet 8 and valve body 1, be provided with valve pocket 12 in the valve body 1, the spool 2 that is provided with sleeve 3 in the valve pocket 12 and cooperates with sleeve 3, valve rod 5 one ends expose bonnet 8, the other end is positioned at valve pocket 12, and be fixedly linked with spool 2, valve rod 5 is provided with annular valve rod boss 13, valve gap 6 in being fixed with between bonnet 8 and the valve body 1, be provided with a cavity 14 in the middle valve gap 6, cavity 14 is connected with valve pocket 12, and cavity 14 upper end-hole are provided with middle spacer ring 7, middle spacer ring 7 and bonnet 8, middle valve gap 6 is tightly connected, middle spacer ring 7 is provided with a mounting hole 15 that supplies valve rod 5 to pass, and also is provided with bellows 4 in the cavity 14, and bellows 4 is enclosed within on the valve rod 5, bellows 4 one ends are sealedly and fixedly connected in middle spacer ring 7 bottoms, bellows 4 the other ends are sealedly and fixedly connected on valve rod boss 13, also comprise the valve seat 18 integrally formed with sleeve 3, and sleeve 3 is provided with the window 17 relative with spool 2, when spool 2 contacted with valve seat 18, spool 2 was blocked window 17 fully.Sleeve 3 all is sealed and matched with the place of valve body 1,6 times end in contact of middle valve gap.
As shown in Figure 1, spool 2 is divided into epicoele and cavity of resorption with valve pocket 12, spool 2 is provided with the equalizing orifice 16 with epicoele and cavity of resorption connection, when actuator drives valve rod 5 when state shown in Figure 1 moves upward, bellows 4 is compressed, spool 2 moves upward under the drive of valve rod 5, spool 2 is opened window 17, the medium that flows into from inlet channel 19 flows out to outlet passage 20 through window 17, the medium at outlet passage 20 places can flow into the epicoele from cavity of resorption along equalizing orifice 16, acts on the unbalanced force of spool about in the of 2 to reduce medium; And because of no matter whether window 17 is opened, outlet passage 20 all communicates with cavity of resorption in the valve pocket 12, and cavity of resorption communicates by equalizing orifice 16 again with epicoele, and promptly the medium of outlet passage 20 communicates all the time with cavity 14 beyond the bellows 4; Because of the pressure of outlet passage 20 is lower than the pressure at inlet passage 19 places, make the bellows outer wall bear lower pressure like this, help prolonging the working life of bellows; In this part medium that equalizing orifice 16 flows into valve pockets 12 epicoeles is closed under the spacer ring 7, beyond the bellows 4, can not flow in the inner chamber of bonnet, middle spacer ring 7 and bellows 4 are as the sealing of first road, and filler still is contained in the packing cavity 9, seals as second road.
As shown in Figure 2, flat hole 15 of processing in the middle of the middle spacer ring 7, one section flat of milling on the cylinder of stage casing valve rod 5, after valve rod 5 is packed in the flat hole 15, the rotating force that takes place in rotating force that produces on the spool 2 or the actuator is all blocked by flat hole 15, valve rod 5 can't rotate, and assurance bellows 4 is not turned round bad.As shown in Figure 1, valve rod 5 is one-piece parts from top to bottom, during assembling bellows 4 is set on the valve rod 5 bellows 4 lower ends argon arc welding and valve rod boss 13 seal weldings; Be inserted in valve rod 5 behind the flat of the flat hole aligning valve rod of middle then spacer ring 7, the bottom seal welding of the upper end of bellows 4 and middle spacer ring 7, part 4,5,7 forms a bellows component like this with argon arc welding.Must be earlier during assembling at the seal washer of putting into suitable for reading of middle valve gap, 13 1 of the valve rod boss of bellows component are penetrated middle valve gap 6, then the screw thread of valve rod 5 bottoms is screwed in the spool 2, and insert pin at spool 2 and valve rod 5 joining sections, do not have between valve rod, middle spacer ring, bellows, the spool like this and relatively rotate.
Sylphon seal sleeve adjusting valve of the present utility model, move up and down by spool, the size that the regulating sleeve window is opened, regulate the flow of medium, bonnet, middle valve gap and valve body are tightly connected successively, in the packing cavity 9 of bonnet, and the filler of packing into, seal packing cavity 9 with Gland 10, compress with pressing plate 11 again on the Gland 10.
In the sylphon seal sleeve adjusting valve of the present utility model, parts such as bonnet, valve body, sleeve, spool, sleeve packing ring all adopt the part of standard cartridges valve, improve part generalization degree between the series product, just increase a middle valve gap, sealed members such as its inner installation bellows are enclosed in medium below the middle spacer ring, beyond the bellows, and are isolated with filler, valve body partly adopts the telescoping valve structure, can bear higher pressure reduction.This product is used to control poisonous, harmful, valuable special media, is again the bigger place of pressure reduction, guarantees positive confinement.
