Description
Technical field
The present invention relates to a kind of plate valve, relate in particular to a kind of plate valve with flow-adjusting characteristics and acoustic attenuation performance.
Background technique
Plate valve is because flow resistance is little, opens and closes laborsavingly, and the feature such as valve body is shorter, mounting point compactness, is widely used in steam and major diameter boiler feed water pipeline.Yet traditional gate valve only have when flashboard in valve complete shut-down position 50% time, just more responsive to the control of flow, and when flashboard is at a high speed and high-density medium flows, can produce violent vibration, therefore traditional plate valve is unfit to do flow control valve.
Summary of the invention
the object of this invention is to provide a kind offlow-rate adjustment plate valve.
The present invention is Flow-rate adjustment plate valve, there is a valve body 1, in valve body 1, be provided with flashboard assembly 17, in the valve body 1 corresponding with flashboard assembly 17, be provided with common valve seat 3 and throttle valve seat 18, between common valve seat 3 and throttle valve seat 18 and valve body 1, be provided with O type circle 2, flashboard assembly 17 upper ends are connected with valve rod 15, on valve rod 15, cover has valve gap 7, between valve gap 7 and valve rod 15, by filler 8, seal, between valve gap 7 and valve body 1, be provided with successively seal ring 14 from bottom to top, pad 13, pendant collet 12 and dunnage 11, form wood closure structure, valve body 1 upper end is connected with support 9, support 9 upper ends are provided with umbrella gear manual driving device 10, flashboard assembly 17 comprises support ring 4, and support ring 4 two ends are provided with brake disc 5, in the middle of brake disc 5, is provided with spring 6, and support ring 4 upper ends are provided with cutting ferrule 16.
The present invention compares with background technique, the useful effect having is: described Flow-rate adjustment plate valve, it changes domestic traditional plate valve only with Truncation, this plate valve adopts the valve seat construction of opening throttle orifice, not only realized the effect of Flow-rate adjustment, and due to the rational deployment of perforate on valve seat, make this plate valve there is the effect of noise elimination.The mangetic core assembly structure that it adopts fits tightly brake disc and perforate valve seat, guarantees the reliability of Flow-rate adjustment.
Accompanying drawing explanation
Fig. 1 is structure cross-sectional schematic of the present invention, in figure: 1. valve body; 2. O type circle; 3. common valve seat; 4. support ring; 5. brake disc; 6. spring; 7. valve gap; 8. filler; 9. support; 10. umbrella gear manual driving device; 11. dunnages; 12. pendant collets; 13. pads; 14. seal rings; 15. valve rods; 16. cutting ferrules; 17. flashboard assemblies; 18. throttle valve seats.Fig. 2 is partial schematic sectional view of the present invention, in figure: 20,21,22,23,24,25,26,27,28,29,30 is flashboard assembly enable possition.
Embodiment
As shown in Figure 1, described Flow-rate adjustment plate valve, include valve body 1, in valve body 1, be provided with flashboard assembly 18, in the valve body 1 corresponding with flashboard assembly 18, be provided with common valve seat 6 and throttle valve seat 17, between common valve seat 6 and throttle valve seat 17 and valve body 1, be provided with O type circle 2, flashboard assembly 18 upper ends are connected with valve rod 15, on valve rod 15, cover has valve gap 7, between valve gap 7 and valve rod 15, be provided with filler 8, between valve gap 7 and valve body 1, be provided with successively seal ring 14 from bottom to top, pad 13, pendant collet 12 and dunnage 11, valve body 1 upper end is connected with support 9, support 9 upper ends are provided with umbrella gear manual driving device 10, flashboard assembly 18 comprises support ring 3, and support ring 3 two ends are provided with brake disc 4, in the middle of brake disc 4, is provided with spring 5, and support ring 3 upper ends are provided with cutting ferrule 16.The hole of described throttle valve seat (18) is circular hole.Described circular hole is pressed equal percentage flow characteristic and is distributed.
Described Flow-rate adjustment plate valve, when mounted, is first respectively charged into O type circle 2 in valve body 1, common valve seat 6 and throttle valve seat 17, more common valve seat 6 and throttle valve seat 17 is packed in valve body 1.Then flashboard assembly 18 assembled and be connected with valve rod 15, then packing in valve body 1, so far main valve assembling is complete.
Described Flow-rate adjustment plate valve be take equal percentage flow characteristic as example, and adjustment stroke is divided into 10 rank, rating curve equation:
q
m=q
mmine
ch
Wherein, q
mmin-minimal adjustment flow, q
m-adjust flux, h-adjustment stroke, c-constant.
The in the situation that of definite fluid nominal pressure and valve nominal diameter, when flashboard assembly is opened into position 0, now the flow by throttle valve seat is the minimum discharge q of equal percentage regulation range
mminor q
m0.Flashboard assembly is opened into the 1/10(position 1 of adjustment stroke), now the flow by throttle valve seat is q
m1, then flashboard assembly is opened into successively to the 2/10(position 2 of adjustment stroke), 3/10(position 3) ..., now the flow by throttle valve seat is q
m2, q
m3..., Flow-rate adjustment percentage k=(q
m (n+1)-q
mn)/q
mn, be definite value.When flashboard assembly is opened into position 10, now the flow by throttle valve seat is the peak rate of flow q of equal percentage regulation range
m10.
The throttle orifice of described throttle valve seat is small sircle hole.Small sircle hole is easily manufacturing not only, and acoustic attenuation performance is good.When fluid outwards discharges through small holes, the diameter of aperture is less, and the frequency of jet noise is higher, and the peak value with this by noise band moves to outside audible sound, reaches and falls low noise object.But, the too little processing difficulties of aperture, and be easy to block.Conventionally the diameter of getting circular hole is 4.5mm to 8mm.In structural design, make the spacing between aperture as far as possible large, avoid forming the environment of large spray, conventionally getting 1.75<b/d<5 ~ 7(b is the spacing between two adjacent apertures, and d is Circularhole diameter), to reach best soundproof effect.
