Abstract
To the disadvantages of the existing mechanical gate valve, such as the difficult-operating switch, the easy-abrading sealing surface, short operating life, etc. the new gate valve applies the principle of hydraulic transmission, the sylphon flashboard is invented. The assistant hand wheel pulls the oil cylinder as hydraulic source. The master and slaved hand wheel are operate separately to conrol the flashboard on/off, thus to ease the operating.
Description
Hydraulic bellows sluice valve is the innovation and creation that belong to the gate valve aspect.Its task is at existing traditional mechanical formula gate valve, in use exists unlatching, closing function power is big, and is not easy to operate, the influence that be detained by impurity easily produces to squeeze on sealing surface and hinders phenomenon, causes seal failure, problems such as initiation is leaked, and working life is short.Developed the application hydraulic transfering principle first, a kind of bellows-type flashboard is provided, major and minor handwheel is operated step by step.Thereby overcome above-mentioned shortcoming,, prolonged working life from having improved the performance of gate valve in essence.
The present invention is provided with a piston oil-cylinder above assistant's wheel, rotated by it and produce oil pressure, by the valve rod center hole, hydraulic oil is delivered to the bellows flashboard again, acts on the diaphragm platen pressurized distending.Valve seat is engaged tightly with platen, guaranteed to close not have and leaked.
Novel structure of the present invention, rapid operation, shear action and good seal performance, long service life is a kind of desirable model utility gate valve.
Figure of description is a structure sectional view of the present invention.Among the figure: 1. bellows flashboard; 2. valve seat; 3. valve body; 4,7. bolt; 5. valve gap; 6. filler; 8. support; 9. backing plate; 10. ball; 11. main handwheel; 12. assistant's wheel; 13. secondary retainer nut; 14. oil cylinder; 15. oil pressure gauge; 16. piston; 17. flat key; 18. locking nut; 19. gland nut; 20. main retainer nut; 21. valve rod; 22. oil hole; 23. gland; 24. lining; 25. pad; 26. inner nut; 27. platen; 28. outer nut; 29. diaphragm; 30. box body.
Annotate: bellows flashboard 1 is by box body 30; Diaphragm 29; Outer nut 28; Platen 27; Inner nut 26 is formed, and it and valve rod 21 are coupled to one symmetrically.Promptly respectively diaphragm 29 is fastened on box body 30 and the left and right sides platen 27, makes to seal in the bellows flashboard 1 sternly by left and right sides inner nut 26 and outer nut 28, high pressure resistant.
Known by accompanying drawing: the present invention takes turns on 12 assistant and by flat key 17 and locking nut 18 secondary retainer nut 13 and oil cylinder 14 is connected into one.Piston 16 and valve rod 21 are integral through spiral marking connection.Main handwheel 11 is connected into one with main retainer nut 20 through flat key 17 and locking nut 18.When rotating main handwheel 11, main retainer nut 20 rotates thereupon, drives valve rod 21 with 1 unlatching of bellows flashboard or close.
Below in conjunction with accompanying drawing to its working principle of implementation of the present invention.
1. during valve opening:
Rotate counterclockwise assistant and take turns 12, drive on secondary retainer nut 13 and the oil cylinder 14 and move, then the oil pressure in the oil cylinder 14 reduces.Hydraulic oil in the bellows flashboard 1 turns back to oil cylinder 14 and carries out release by the center hole of valve rod 21, and this moment, left and right sides diaphragm 29 and platen 27 shrank, and valve seat 2 and left and right sides platen 27 are separated.Main handwheel 11 begins to start, and rotates counterclockwise, and drives main retainer nut 20 valve rod 21 and bellows flashboard 1 are mentioned valve opening.
2. during valve closing:
Clockwise rotate main handwheel 11, valve rod 21 and bellows flashboard 1 are moved down into closed position.Impacting force takes turns 12 by assistant then provides, it is clockwise rotated, drive secondary retainer nut 13 and oil cylinder 14 moves down, oil pressure in the oil cylinder 14 is risen, hydraulic oil is delivered to bellows flashboard 1 by valve rod 21 center holes, this moment left and right sides diaphragm 29 pressurized distendings, left and right sides platen 27 engages valve closing with valve seat 2.
When no matter the present invention is opening and closing, draw for a short time always its bellows flashboard earlier by hydraulic pressure, decomposes steering force, so it has not only withstand voltage but also labour-saving effect.
