Description
Technical field
The utility model relates to a kind of butterfly valve drive unit, and specifically, the utility model relates to a kind of butterfly valve drive unit that is provided with manual-operated emergent mechanism.
Background technique
The existing butterfly valve that is driven by ram generally drives the fork swirl gear that is connected with the valve rod of butterfly valve by ram, realizes the rotation of valve rod, thereby the realization butterfly valve is opened and be closed.Adopt ram to drive and have laborsaving, convenience operation.If but abnormal conditions appear in ram or when hindering the operation of valve owing to the shortage of dynamic medium, piston rod can't normally move, and just can't pass through fork mechanism rotation valve rod, will influence that butterfly valve is opened and closed.At this moment, just can't realize as unlatching of needs butterfly valve and closure.A kind of butterfly valve manual-operated emergent drive unit is disclosed in the patent of Chinese patent publication number CN201582408U " butterfly valve manual-operated emergent drive unit ": realize that by pinion and rack manual-operated emergent drives, this structure can realize the emergent driving of butterfly valve, but its defective is: the pinion and rack complex structure, the accuracy of manufacturing height, the manufacture cost height.Another kind of butterfly valve manual-operated emergent drive unit is disclosed in the patent of Chinese patent publication number CN201582407U " butterfly valve meet an urgent need manual structure ": realize that by screw mechanism manual-operated emergent drives, this structure can realize the emergent driving of butterfly valve, but its defective is: need artificial screw mechanism screw axis is connected with piston rod thread before needing manual-operated emergent to drive, when need not the manual-operated emergent driving, also need manually screw mechanism screw axis and piston rod to be thrown off, operation is very complicated like this, time-consuming bothersome, in case of emergency cause delay easily.In addition, in the technological scheme of these two patents, all can't when manual-operated emergent drives, the butterfly valve unlatching be fixed on the position that needs.
The model utility content
The utility model is at the deficiencies in the prior art, propose a kind of simple in structure, low cost of manufacture, swift to operate, convenient, manual-operated emergent can be fixed on butterfly valve the manual-operated emergent formula butterfly valve drive unit of the enable possition that needs when driving.
The utility model is achieved through the following technical solutions technical goal.
Manual-operated emergent formula butterfly valve drive unit is arranged on the butterfly valve top, comprises the nutation type driving mechanism, is connected the ram of its right-hand member; Described nutation type driving mechanism comprises the housing that is fixedly connected on the butterfly valve top, is built in the fork in the housing inner chamber; Described fork is fixedly connected on butterfly valve valve rod end, constitutes beat mechanism; Described ram by the piston rod medial side face diameter that stretches out left to the bearing pin that connects and the Spielpassung of fork opening slot, the formation driving mechanism; Described ram two ends are provided with off-load and take over; Its improvements are: described piston rod left end shaft outer wall is provided with square threaded form; Be provided with manual-operated emergent mechanism at the piston rod left end; Described manual-operated emergent mechanism comprises handwheel, lining, stop screw; Described handwheel is threaded with the piston rod left end; Described lining is linked on the axle sleeve that handwheel extends to the right, with the axle sleeve Spielpassung; Described lining setting-in also is fixedly connected on the housing left end; Described handwheel extends the axle sleeve outer wall to the right and is provided with radially annular groove, and described stop screw is the penetration liner outer wall radially, and its end is stretched in the radially annular groove that handwheel extends the axle sleeve outer wall to the right, constitutes hand wheel shaft to limit structure.
As the preferred version of such scheme, described lining is fixedly connected on the housing left end by fastening screw trip bolt.
When something unexpected happened need be adjusted the working state of butterfly valve immediately, opening the off-load at ram two ends earlier takes over, rotation hand wheel piston rod axial displacement then drives beat mechanism by piston rod and drives valve rod and rotate, thereby realizes the quick unlatching of butterfly valve fast or close; If desired butterfly valve is fixed on the enable possition that needs, then when butterfly valve is opened to this position, adjusts stop screw, withstand the radially annular groove that handwheel extends axle sleeve to the right with the stop screw end, handwheel can't rotate, and then butterfly valve is fixed on the enable possition that needs.
The utility model compared with prior art has following good effect:
1. simple in structure, low cost of manufacture.
2. can solve the emergent driving problems of butterfly valve hydraulic pressure, pneumatic actuating device.
3. just can realize that manual-operated emergent drives as long as rotate handwheel, easy to operate, quick.
4. butterfly valve can be fixed on the enable possition that needs when manual-operated emergent drives.
