Abstract
The invention discloses a manual emergent butterfly valve driving device which is arranged at the top end of a butterfly valve and comprises a deflection driving mechanism and a manual emergent mechanism and a power cylinder which are connected at the left end and the right end of the deflection driving mechanism respectively. The deflection driving mechanism comprises a casing and a poking fork. A pin roll in radial connection with the side of the middle of a piston rod of the power cylinder stretching leftwards is in clearance fit with a poking fork opening groove. Rectangular threads are arranged on the outer wall of the rod body at the left end of the piston rod. The manual emergent mechanism comprises a hand wheel, a lining and a limit screw. The hand wheel is in threaded connection with the left end of the piston rod. The lining sleeves a shaft sleeve of the hand wheel extending rightwards to be in clearance fit with the shaft sleeve. The lining is embedded in and fixedly connected with the left end of the casing. A radial annular groove is formed in the outer wall of the hand wheel shaft sleeve, the limit screw penetrates the outer wall of the lining in the radial direction, and the end portion of the limit screw stretches into the radial annular groove in the outer wall of the shaft sleeve of the hand wheel to form a hand wheel axial limit structure. The manual emergent butterfly valve driving device is simple in structure, low in manufacture cost, quick and convenient to operate and capable of being fixed at the required opening position during manual emergent driving.
Description
Technical field
The present invention relates to a kind of butterfly valve drive unit, specifically, the present invention relates to a kind of butterfly valve drive unit that is provided with manual-operated emergent mechanism.
Background technique
The existing butterfly valve being driven by ram generally drives by ram the fork swirl gear being connected with the valve rod of butterfly valve, realizes the rotation of valve rod, thereby realizes butterfly valve opening and closing.Adopt ram to drive and there is laborsaving, easy to operate feature.If but ram is while occurring that abnormal conditions or the shortage due to dynamic medium hinder the operation of valve, piston rod cannot normally move, and just cannot pass through shifting fork mechanism rotation valve rod, will affect butterfly valve opening and closing.At this moment, as needs butterfly valve opening and closing just cannot realize.A kind of butterfly valve manual-operated emergent drive unit is disclosed in the patent " butterfly valve manual-operated emergent drive unit " of China Patent Publication No. CN201582408U: realize manual-operated emergent by pinion and rack and drive, this structure can realize the emergency driving of butterfly valve, but its defect is: pinion and rack complex structure, accuracy of manufacturing is high, and manufacture cost is high.In the patent of China Patent Publication No. CN201582407U " butterfly valve meet an urgent need Manual structure ", another kind of butterfly valve manual-operated emergent drive unit being disclosed: realizes manual-operated emergent by screw mechanism and drive, this structure can realize the emergency driving of butterfly valve, but its defect is: before needing manual-operated emergent to drive, need artificial screw mechanism screw axis to be connected with piston rod thread, while driving without manual-operated emergent, 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 easily cause delay.In addition, in the technological scheme of these two patents, all cannot in the time that manual-operated emergent drive, butterfly valve be opened and be fixed on the position needing.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose one 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 needing while driving.
The present invention is achieved through the following technical solutions technical goal.
Manual-operated emergent formula butterfly valve drive unit, is arranged on butterfly valve top, comprises nutation type driving mechanism, is connected to the ram of its right-hand member; Described nutation type driving mechanism comprise be fixedly connected on butterfly valve top housing, be built in the fork in housing inner chamber; Described fork is fixedly connected on butterfly valve valve rod end, forms deflection mechanism; Described ram by the piston rod medial side face diameter that stretches out left to the bearing pin connecting and the Spielpassung of fork opening slot, 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 piston rod left end; Described manual-operated emergent mechanism comprises handwheel, lining, stop screw; Described handwheel is threaded with piston rod left end; Described lining is linked on the axle sleeve that handwheel extends to the right, with axle sleeve Spielpassung; Described lining setting-in is also fixedly connected on housing left end; Described handwheel extends axle sleeve outer wall to the right and is provided with radially annular groove, and described stop screw is penetration liner outer wall radially, and its end is stretched in the radially annular groove that handwheel extends axle sleeve outer wall to the right, forms handwheel axial limit structure.
As the preferred version of such scheme, described lining is fixedly connected on housing left end by fastening screw trip bolt.
When something unexpected happened need to be adjusted the working state of butterfly valve immediately, first opening the off-load at ram two ends takes over, then rotation hand wheel piston rod axial displacement, drives deflection mechanism band ovable valve stem to rotate by piston rod, thereby realizes fast the quick unlatching of butterfly valve or close; If butterfly valve need to be fixed on to the enable possition needing, in the time that butterfly valve is opened to this position, adjust stop screw, withstand handwheel and extend the radially annular groove of axle sleeve to the right with stop screw end, handwheel cannot rotate, and butterfly valve is fixed on the enable possition of needs.
The present invention compared with prior art, has following good effect:
1. simple in structure, low cost of manufacture.
2. can solve the emergency driving problem of butterfly valve hydraulic pressure, pneumatic actuating device.
3. just can realize manual-operated emergent driving as long as rotate handwheel, easy to operate, quick.
4. when manual-operated emergent drives, butterfly valve can be fixed on to the enable possition needing.
