Abstract
The utility model provides a connecting and positioning device between a valve shaft and a valve plate of a butterfly valve, relates to the field of valve manufacturing technology, and particularly discloses a connecting and positioning and torsion transmitting device between the valve shaft and the valve plate of the butterfly valve. The valve plate comprises valve clacks and a valve shaft seat. A vertical through hole is formed in the valve shaft seat and used for the valve shaft to penetrate through. A round positioning hole is formed in the valve shaft seat in a horizontal mode and used for positioning and connecting the valve shaft. A wedge groove is arranged in a position, contacting with the round positioning hole, of one side of the valve shaft, and a wedge columnar pin is arranged in the round positioning hole in a penetrating mode. The diameter of a large round end of the wedge columnar pin is the same as that of the round positioning hole, and one face contacting with the valve shaft, of the wedge columnar pin is an inclined face matched with the wedge groove of the valve shaft. The connecting and positioning device is easy to machine and manufacture, convenient to assemble and disassemble, large in transmitted torque, and high in production and assembly efficiency. Moreover, the wedge columnar pin can be repeatedly used, materials are saved, and cost is reduced.
Description
Technical field
The utility model relates to technical field of valve manufacturing, is connected location, transmitting torque device between the valve shaft that is specially butterfly valve and the valve plate.
Background technique
In the prior art between the valve shaft of butterfly valve and the valve plate the general taper pin that adopts be connected, this Placement need to be joined work in assembly process, join that to make difficulty large, efficient is low, and the difficulty of producing in batches at assembly line is large, and taper pin has just been scrapped after the dismounting, can't reuse, increase cost.
Summary of the invention
It is higher that the purpose of this utility model provides a kind of efficient, the valve shaft of the butterfly valve of convenient disassembly and the connection locator between the valve plate.
The technological scheme that realizes above-mentioned purpose is: the valve shaft of butterfly valve and the connection locator between the valve plate, it is characterized in that: described valve plate comprises flap and valve shaft seat, the valve shaft seat is provided be used to the vertical through holes that places valve shaft, be provided with circular positioning hole be used to the lateral arrangement of the valve shaft that is located by connecting at the valve shaft seat, side at valve shaft, the position that contacts with circular positioning hole is provided with wedge slot, in circular positioning hole, placed the wedge shape pin, the diameter of described wedge shape pin great circle one end is identical with the diameter of circular positioning hole, and the one side that the wedge shape pin contacts with valve shaft is the plane of inclination of matching with the wedge slot of valve shaft.
The utility model is easy to processing and fabricating, assembling, convenient disassembly, and carry-over moment is large, produce,
Efficiency of assembling is high, and wedge shape pin of the present utility model is reusable, has saved material, has reduced cost.
