Abstract
The invention discloses a multifunctional universal type balance valve, which belongs to the filed of invention and creation of universal cutoff valves and control regulating valves. The task of the multifunctional universal type balance valve aims to solving problems that in the prior traditional mechanical type cutoff valve and the regulating valve, a valve clack (a valve core) has large stress, the valve is time-consuming and laborious to open and close in the using process, and the aperture of the valve is also restricted by pressure difference and cannot be randomly changed, so the valve is not applied in middle- pressure and high-pressure occasions. The invention initially develops and applies a balanced pressure difference principle of a pilot valve and provides a combined balance valve clack (valve core); a medium is controlled by the pilot valve and acts on a piston to generate thrust; and the thrust and pressure acting on the valve clack (the valve core) are counteracted with each other to achieve balance. The multifunctional universal type balance valve has large aperture, high-pressure resistance, convenient operation, labor conservation and long service life, and the closing of the balance valve can reach the standard of zero leakage. The multifunctional universal type balance valve substantially improves the performances of the cutoff valve and the regulating valve and greatly widens the application range; and therefore, the multifunctional universal type balance valve is a perfect balance valve.
Description
Multifunctional general balance valve is to belong to universal cutoff valves and regulating and controlling valve, the innovation and creation of two big valve field aspects.Its task is to existing traditional mechanical formula stop valve and modulating valve; It is stressed big in use to exist flap (spool); Valve opening, close time-consuming, effort, also pressure difference restriction of valve aperture in addition then can not be toward the heavy caliber development; Thereby this valve is in middle and high pressure, and the heavy caliber occasion can not get using.The present invention is development and Application pilot valve balance pressure reduction principle first, and two kinds of independences " combined type balance valve core " are provided, that is: a kind of is cylinder window spool; Another kind is a plungers valve core, and each spool and valve hole part are formed " combined type balance valve core ", in use all can be with medium through pilot valve control; Act on the piston; Produce thrust, and cancel each other, reach balance with the pressure that spool receives.Thereby overcome above-mentioned shortcoming,, also widened Applicable scope simultaneously greatly from having improved the performance of stop valve and modulating valve in essence.
The present invention is provided with a piston cylinder below valve gap; Between piston and spool, also be provided with splice sleeve; Guide's spool is located in the sleeve pipe, and by valve rod and the control of butterfly spring, makes " combined type balance valve core " in valve opening or pass closed procedure, all be in state of equilibrium all the time.Therefore not pressure difference restriction of the present invention, so the valve rod ouput force is little, it was both convenient, laborsaving again to operate.
The present invention is simple in structure, novel, and is high pressure resistant, rapid operation, and good seal performance, long service life is a kind of desirable model utility equilibrium valve.
Figure of description is a structure sectional view of the present invention.Among the figure: 1. butterfly spring; 2. cylinder window spool; 3. valve body; 4. valve seat; 5. piston; 6. pad; 7. double-screw bolt; 8. nut; 9. valve gap; 10. hold-down grid; 11. lower valve rod; 12. adjustable bolt; 13. priming cup; 14. support; 15. handwheel; 16. nut; 17. flat key; 18. upper valve rod; 19. Stem Mut; 20. connecting sleeve; 21. straight pin; 22. bolt; 23. open loop pad; 24. filler gland; 25. filler; 26. lining; 27. guide's spool; 28. splice sleeve; 29. plungers valve core; 30. locking nut.
Annotate: combined type balance valve core: by butterfly spring 1; Cylinder window spool 2; Piston 5; Guide's spool 27; Splice sleeve 28; Plungers valve core 29; Locking nut 30 is formed; Wherein piston 5 and cylinder window spool 2 or plungers valve core 29, screw thread or welding through splice sleeve 28 respectively are combined into one two kinds of spools respectively, constitute two covers difform " combined type balance valve core "; Its two cover " combined type balance valve core " can be realized four kinds of exemplary traffic characteristics respectively; That is: linear flow flow characteristic, equal percentage (logarithm) Flow characteristics, quick open flow characteristic and parabolic flow character.Guide's spool 27 upper ends are integral by being threaded with lower valve rod 11 in addition, and its lower end adopts nut 30 that butterfly spring 1 is pinned.Shown in accompanying drawing.
Cylinder window spool 2: adopted half sectional view (left hand half is a cylinder window spool 2) in the accompanying drawings, had the cylinder window on its cylinder barrel, to satisfy straight line or quick open flow characteristic requirement.
Plungers valve core 29: also adopt half sectional view (right side one side of something is a plungers valve core 29) in the accompanying drawings, it can satisfy equal percentage (logarithm) or parabolic flow character requirement.
The present invention by flat key 17 and locking nut 16, is connected into one with valve rod 18 on handwheel 15.Stem Mut 19 is screwed in support 14 upper ends, connecting sleeve 20 is arranged below it, is connected into one through straight pin 21 and lower valve rod 11.By bolt 22 and open loop pad 23 support 14 is fixed on the valve gap 9 in addition, forms an integral body.When handwheel 15 rotated, upper valve rod 18 also rotated, and lower valve rod 11 also moves thereupon, drove the combined type balance valve core and opened or close.
Below in conjunction with accompanying drawing embodiments of the invention are explained its working principle.
1. during valve opening:
Rotate counterclockwise handwheel 15, then upper valve rod 18 rotates synchronously, drives connecting sleeve 20; Straight pin 21 moves down with lower valve rod 11, and this moment, straight pin 21 slided in support 14 vertical slots, and about do not turn round; When lower valve rod 11 moved down, guide's spool 27 at first began to open, and medium flows to low pressure piston chamber, upper end by the endoporus of lower end high pressure through splice sleeve 28; Along with the continuous inflow of medium, last downforce tends to balance, so handwheel 15 rotates; Not pressure difference restriction, it is all very light to cause valve opening or closing operation.
2. during valve closing:
Clockwise rotate handwheel 15, lower valve rod 11 is mentioned guide's spool 27, simultaneously because the tension force effect of butterfly spring 1; Make guide's spool 27 still be in opening state, like this " combined type balance valve core " but non-resistance moves up and pressure differences not; So medium by top be back to gradually below, close when putting in place until " combined type balance valve core ", butterfly spring 1 is by the pulling of the valve rod of guide's spool 27 (trace pulling); Make 1 compression of butterfly spring, guide's spool 27 is closed and is put in place, and this moment, medium was static mobile.
No matter the present invention is valve aperture differential pressure size, is opening or is closing in the closed procedure, and two covers independent " combined type balance valve core " always are in state of equilibrium, not limited by any pressure reduction, bore, so it are both high pressure resistant, rapid operation again, and sealing reaches zero leakage.
