Abstract
To the disadvantages of the existing mechanical track ball valve, such as the difficult-operating switch, the easy-abrading sealing surface, short operating life, etc. The new valve applies the principle of hydraulic transmission, the sylphon sealing ring is invented. The assistant guiding wheel pulls the oil cylinder as hydraulic source. The master and slave guiding rail are operate separately to control the sealing ring on/off thus to ease the operating.
Description
Hydraulic bellows guide rail ball valve is the innovation and creation that belong to the ball valve aspect.Its task is at the soft seal ball-valve of existing traditional mechanical formula, in use can not adapt to the needs of high temperature, high pressure occasion.Problems such as it is easy to wear to exist sealing ring material in addition, causes seal failure, causes to leak, and working life is short.Developed the application hydraulic transfering principle first, a kind of bellows-type seal ring is provided, it is hydraulic power that handwheel drives oil cylinder, adopts guide rail to operate control spheroid open and close step by step.Thereby overcome above-mentioned shortcoming,, prolonged working life from having improved the sealability of ball valve in essence.
The present invention is provided with piston oil-cylinder above handwheel, be provided with driven guide rail sleeve and valve rod locating stud and guider screw below it, and a mantle cartridge seal circle respectively is set in the spheroid both sides.When valve closing, forward spheroid to 0 degree (position, pass) by 90 degree (open position), its handwheel clockwise rotates, and drives oil cylinder respectively and driven guide rail sleeve moves down, before this because one section no oily space is arranged at the cylinder chamber top, form negative pressure, sphere Contact Seal ring not when spheroid rotates.When driven guide rail sleeve forwards valve rod to 0 when spending, the cylinder chamber pasta touches the cylinder top cover, and this moment, oil cylinder began to boost, and hydraulic oil is delivered to bellows by valve rod center hole and oil pipe, acts on the diaphragm, and platen pressurized distending makes sphere engage with seal ring.Sphere forwards 90 degree to by 0 degree when valve opening, and handwheel rotates counterclockwise, and at first oil cylinder is carried out release, and bellows hydraulic oil returns oil cylinder, and sphere separates with seal ring, and driven then guide rail sleeve forwards valve rod to 0 degree and causes valve opening.
Novel structure of the present invention, hard, soft seal all can, good seal performance does not have friction, long service life is a kind of desirable model utility ball valve.
Figure of description 1 is a structure sectional view of the present invention.Among the figure: 1. valve body; 2. pad; 3. bellows; 4. flange seat; 5. locking nut; 6. oil pipe lower interface; 7,34. double-screw bolts; 8. filler; 9. gland; 10. locating stud; 11. interface on the oil pipe; 12. ball; 13. screw; 14. handwheel; 15. flat key; 16. cylinder cap; 17. piston; 18. oil pressure gauge; 19. oil cylinder; 20. valve rod; 21. retainer nut; 22. driven guide rail sleeve; 23. handwheel gland; 24. oil pipe; 25. guider screw; 26. suspension ring double-screw bolt; 27. lining; 28. seal ring; 29. spheroid; 30. diaphragm; 31. platen; 32. backing plate; 33. axle bed.
Fig. 2 is the partial sectional view of I among Fig. 1.Among the figure: 22. driven guide rail sleeves; 10. locating stud; 11. interface on the oil pipe; 36. positioning guide rail; 25. guider screw; 35. divert guide track.
Annotate: bellows 3 is by flange seat 4; Diaphragm 30; Platen 31; Locking nut 5; Valve body 1 composition such as grade.Its flange seat 4 is pushed down diaphragm 30 with valve body 1 and locking nut 5 respectively, makes to seal in the bellows 3 sternly, and is high pressure resistant.30 outer rings of this outer membrane and platen 31 collar wall are connected into one, enter the valve body lumen to avoid medium, cause leakage.Hence one can see that, and the bellows-type seal ring then is made of bellows 3 and seal ring 28.
Know by accompanying drawing 1: the present invention on handwheel 14 by screw 13; Flat key 15 is with handwheel gland 23; The retainer nut 21; Cylinder cap 16 and oil cylinder 19 tightly join together.Piston 17 and valve rod 20 are integral through spiral marking connection.When rotating handwheel 14, oil cylinder 19 rotates thereupon.In handwheel gland 23, cooperate simultaneously, through guider screw 25 effects, will drive valve rod 20, make it open and close 90 degree conversions by locating stud 10 from driven guide rail sleeve 22 by upper and lower ball 12.
Known by accompanying drawing 2: have two cover positioning guide rail 36 and divert guide track 35 of symmetry on driven guide rail sleeve 22, the corner between its two covers guide rail becomes 45 degree location.
Below in conjunction with accompanying drawing to its working principle of implementation of the present invention.
1. during valve closing:
Clockwise rotate handwheel 14 and drive oil cylinder 19 and driven guide rail sleeve 22 respectively, driven guide rail sleeve is under the effect of guider screw 25, oblique rail section along divert guide track 35 moves down earlier, moving down along perpendicular rail section subsequently, meanwhile positioning guide rail 36 is by locating stud 10 effects, valve rod 20 and driven guide rail sleeve 22 are rotated synchronously, make it substep and finish 90 and spend corners and oil cylinder boosts.Because one section no oily space is arranged at the cylinder chamber top, form negative pressure before this, sphere and seal ring 28 do not produce friction when spheroid 29 rotates, as shown in Figure 1.When driven guide rail sleeve 22 forwarded valve rod 20 to perpendicular rail section, the cylinder chamber pasta touched the cylinder top cover, and this moment, oil cylinder 19 began to boost, hydraulic oil is delivered to bellows 3 by valve rod 20 center holes and oil pipe 24, acts on the diaphragm 30, platen 31 pressurized distendings make sphere engage valve closing with seal ring.
2. during valve opening:
Rotate counterclockwise handwheel 14, drive on the driven guide rail sleeve 22 and move, at first it carries out release in the perpendicular rail section of divert guide track 35 with oil cylinder 19, and this moment, the hydraulic oil of bellows 3 turned back to oil cylinder 19 rapidly, and diaphragm 31 and platen 30 shrink, and seal ring 28 and sphere are separated.In oblique rail section valve rod 20 is rotated 90 degree then, cause valve opening.
No matter in the process of opening or closing, its spheroid 29 surfaces are non-contacts with seal ring 28 forever in the present invention, and 28 pairs of spheroid 29 surfaces of seal ring do not produce friction, therefore have effect hard, that soft seal all takes into account.
