Abstract

The invention discloses a special strong-poison composite bellows valve (hereinafter referred to as special strong-poison valve), and belongs to inventions and innovations in anticorrosion valves in the field of chemical engineering. The special strong-poison valve aims to solve the problem that a bellows in a conventional steel-lined fluorine plastic bellows single-seat valve has poor flexibility, is liable to crack and has a short service life when used under a poisonous and harmful medium condition, wherein the bellows is made from polytetrafluoroethylene, is used for sealing a valve rod to prevent medium leakage and is the main core part of the conventional steel-lined fluorine plastic bellows single-seat valve. A bellows made from a special alloy can overcome the defects, but is too high in manufacturing cost to be accepted by lots of manufacturers. The special strong-poison valve makes an innovation in the conventional bellows according to the static plastic spraying principle to manufacture a composite bellows, has the characteristics of high flexibility, high corrosion resistance, long service life, moderate cost and the like and is applicable to poisonous and harmful medium conditions in chemical engineering.

Description

A kind of compound bellows severe toxicity special valve
The invention discloses " a kind of composite corrugated hypertoxic special valve " (hereinafter referred to as hypertoxic special valve), it belongs to the innovation and creation of aspect, anticorrosive valve field.Its task is for existing steel lining fluorine plastic film capicitor single-seat valve, and in use the bellows made of teflon, also exists telescopic resilience difference, easy-rupturing, the problems such as working life is short.If the bellows using special alloy to make existing, it can overcome above-mentioned defect, but manufacture cost is but very high, and a lot of producer also can not accept at present.In addition existing bellows single-seat valve, also also exists valve flowing channel not smooth, especially dead angle place, washes away seriously by medium, as: valve seat and spool two counterparts often wear and tear, and are easy to damage, therefore cause valve cannot continue to use.
In sum, the bellows of the present invention's development is that one can meet special hypertoxic working condition requirement, the cost of valve can be made again to lower, the novel hypertoxic special valve that both can take into account.The present invention's application electrostatic plastic spraying principle, first by fluorine rubber cylinder-packing on metal barrel, its metal cylinder play supporting role, and be lined with fluororubber layer at its outer wall, this is in order to the corrosion-resistant plastic-blasting bottom done, and after then making bellows, then applies electrostatic plastics-spraying technology and carries out anticorrosive coat processing.Therefore through the compound bellows that above-mentioned technique is made, there is good springiness, the features such as anti-corrosive properties are strong, long service life, moderate.On this basis, the present invention innovates on valve flowing channel, changes valve body inlet obliquely inserting type runner into horizontal run, be designed to streamline in body cavity corner simultaneously, and on fluorine-lining valve seat, studding with the alloy valve seat of anticorrosion antiwear, spool adopts full alloy to make, and can wash away by anti-medium.It can thus be appreciated that the novel hypertoxic special valve of the present invention, opens at spool, when cutting out, spool and valve seat fitted seal lastingly, non-internal leakage, and media-resistant washes away.
The present invention fundamentally solves the drawback that existing bellows single-seat valve exists, therefore effectively raises the sealability of valve, also ensure that working life simultaneously.
Pipe, by stud, connects and is pressed between valve gap and valve body by the present invention, forms one, and bellows upper flanges is also pressed in wherein, and valve rod lower end screw thread coordinates with valve core nut to be tightened, by end flange fixing and locking under bellows, valve rod is made to form sealing, without leaking outside medium.Bonnet flange has two Screw rod bearings handwheel pressing plates, nut by handwheel pressing plate and bonnet flange locked, make it integral.Upper valve rod engages by contiguous block with lower valve rod, forms revolution.When valve opening or when closing, rotate handwheel, upper valve rod drives lower valve rod and spool to move up and down thereupon, controls given flow, can control value to reach.
Structure of the present invention is simple, novel, practical, operates light, good seal performance, long service life, is a kind of desirable invention severe toxicity special valve.
Figure of description is structure sectional view of the present invention.In figure: 1. valve body; 2. serve as a contrast fluorine layer; 3. alloy valve seat; 4. spool; 5.O shape is enclosed; 6. compound bellows; 7. pipe connects; 8. lower valve rod; 9. limiting bush; 10. valve gap; 11 fillers; 12. screw rods; 13. contiguous blocks; 14. bearing plates; 15. upper valve rods; 16. handwheels.
Below in conjunction with accompanying drawing, its working principle is illustrated to embodiments of the invention.
1. during valve opening:
Rotate counterclockwise handwheel 16, then upper valve rod 15 synchronous axial system, contiguous block 13 and lower valve rod 8 is driven to move up, now the curve bath of contiguous block 13 vertically slides along screw rod, and left and right is not turned round, when lower valve rod 8 mentions spool, compound bellows 6 is compressed, it seals isolated to lower valve rod 8 and medium, and the filler 11 of valve gap 10 does again the use of secondary seal simultaneously.So cause valve opening, medium enters from the left side, by spool choked flow, flows out to the right.
2. during valve closing:
Rotate clockwise handwheel 16, upper valve rod 15 synchronous axial system, drive contiguous block 13 and lower valve rod 8 to move down, now compound bellows 6 is stretched, and spool 4 engages with valve seat 3, forms sealing, causes valve closing.
The present invention selects special material due to spool 4 and valve seat 3 simultaneously, and compound bellows 6 has pull resistance again in addition, and therefore novel hypertoxic special valve working life can durable, and it is a kind of reliable novel good product.
