Abstract
The invention relates to a novel butterfly valve, which comprises a drive valve, a driven valve, a guide pin, a guide sleeve, a drive shaft, a driven shaft, a drive valve plate, a driven valve plate and circular rubber sealing rings; and the drive valve and the driven valve are connected through the guide pin and the guide sleeve to make the double-opening butterfly valve realize opening and closing; the drive shaft and the drive valve plate are connected into a whole; likewise, the driven shaft and the driven valve plate are also connected into a whole; and the circular rubber sealing rings are arranged on the peripheries of the drive valve plate and the driven valve plate respectively. The novel butterfly valve has high production efficiency, easy detachment, easy cleaning and no secondary pollution and can realize free opening and closing under a closeness condition.
Description
(1) technical field
What the present invention relates to is a kind of novel butterfly valve, is specifically related to a kind of double-opening butterfly valve that is applied to industries such as pharmacy, food, chemical industry.
(2) background technique
The butterfly valve that is applied to industries such as medicine, food, chemical industry at present is single opening structure, in material cycling, have phenomenons such as pollution, exposure, oxidation in the butterfly valve working procedure and since the unlatching of butterfly valve be manual operations, efficient low, secondary pollution takes place easily.
(3) summary of the invention
The object of the present invention is to provide a kind of double-opening butterfly valve of a kind of manufacturing efficiency height, quick detachable, easy cleaning, no secondary pollution, promptly aggressive valve and passive valve can realize freely opening under airtight situation.Guarantee that material is not contaminated in turnover.
The object of the present invention is achieved like this: this device is formed by connecting by two guide pillars, guide pin bushings by aggressive valve and passive valve, can guide pillars and bushes be moved up and down with machinery or cylinder during work, the aggressive valve of double-opening butterfly valve is reached with passive valve separate and combination.In conjunction with BB1 can with manually or pneumatic actuator carry out rotation and locking, can opened butterfly valve after the locking, can be with manually during unlatching, also available pneumatic actuator is realized.
The present invention can also comprise some technical characteristicss like this:
1. the axle head of driving shaft on aggressive valve and the passive valve and driven axle all has inlet hole, is connected with the round rubber seal ring of valve plate periphery with passive valve plate through the active valve plate, and therefore initiatively the sealing of valve plate and passive valve plate is to adopt hermetic seal.
2. aggressive valve is connected by two guide pillars and bushes with passive valve, can make aggressive valve and passive valve opening and closing by the effect of steam-operating or machinery.
3. after aggressive valve and the passive valve closure, can be by pneumatic actuator or manually make the guide gip rotation realize locking.
4. after the locking of aggressive valve and passive valve, by pneumatic actuator or manual rotation valve plate 90 initiatively since this moment aggressive valve and passive valve be in locked state, so also opened passive valve simultaneously.
(4) description of drawings
Fig. 1 is the closed schematic representation of double-opening butterfly valve.
Fig. 2 is that double-opening butterfly valve is opened schematic representation.
Fig. 3 is a double-opening butterfly valve overall structure schematic representation.
(5) embodiment
The invention is further described for example below in conjunction with accompanying drawing:
Form by aggressive valve 1 and passive valve 2 two-part in conjunction with Fig. 1, double-opening butterfly valve,, make double-opening butterfly valve realize opening and closing through being connected of guide pillar 3 and guide pin bushing 4.
Fuse in conjunction with Fig. 2, driving shaft 8 and active valve plate 6, same driven axle 7 and passive valve plate 5 also fuse, and round rubber seal ring 9 is to be contained in respectively on the periphery of active and passive valve plate.
Claims (4)
1. a novel double-opening butterfly valve is connected and forms with round rubber seal ring (9) by aggressive valve (1), passive valve (2), guide pillar (3), guide pin bushing (4), passive valve plate (5), active valve plate (6), driven axle (7), driving shaft (8); Aggressive valve (1) and passive valve (2) can realize opening simultaneously under airtight situation.
2. according in right 1 described aggressive valve (1) and the passive valve (2) driving shaft (8) and driven axle (7) being arranged, its axle head all has inlet hole, is connected with round rubber seal ring (9) through active valve plate (6) and passive valve plate (5) and realizes hermetic seal.
3. be connected with guide pin bushing (4) by two guide pillars (3) with passive valve (2) according to right 1 described aggressive valve (1), can by manually and the effect of cylinder make that aggressive valve (1) and passive valve (2) are opened, closure.
4. according to after right 1 described aggressive valve (1) and the closed also locking of passive valve (2), the unlatching of butterfly valve is to drive passive valve plate (5) by driving shaft (8) together with aggressive valve (1) to open butterfly valve simultaneously.
