Abstract
The utility model relates to a fixing device of butterfly valve rod and valve clack, it mainly includes valve rod (1), valve clack (2) and fixed pin (3), valve rod (1) connection valve clack (2) position be with radial inclined plane that becomes 25, valve clack (2) connection valve rod position be the round hole, fixed pin (3) for having the inclined plane cylindric lock of boss, inclined plane angle is 25. During assembly, the fixing pin (3) is knocked into the round hole of the valve clack (2) and is overlapped and pressed with the inclined plane of the valve rod (1). When the valve is disassembled, the fixing pin is taken out by utilizing the lug boss on the fixing pin (3), so that the valve rod (1) and the valve clack (2) are separated. The utility model has the advantages of fixed pin (3) one side is the inclined plane, and one side is the cylinder, and pressure is bigger the contact of valve rod (1) and valve clack (2) is tighter, becomes extrusion stress with the shear stress transformation of fixed pin (3), has increased the life-span of fixed pin (3), makes the sealing performance of butterfly valve obtain long-term assurance. The boss on the fixing pin (3) provides convenience for disassembling the valve rod (1) and the valve clack (2) of the butterfly valve.
Description
Technical Field
The utility model relates to a fixing device of butterfly valve rod and valve clack prevents the relative rotation of butterfly valve rod and valve clack through this device, and then guarantees the stability of butterfly valve switch operation.
Background
The valve rod and the valve clack of the butterfly valve are usually connected through the cylindrical pin, when the butterfly valve is opened and closed, the cylindrical pin is subjected to large shearing stress, and the cylindrical pin is easy to loosen or damage after multiple actions, so that the valve rod and the valve clack are separated, and the valve action fails. In order to prevent the above situation, the fixing device of the valve rod and the valve clack of the butterfly valve is designed, and the service life of the butterfly valve is prolonged.
Disclosure of Invention
The utility model aims at providing a fixing device of butterfly valve rod and valve clack.
The technical scheme of the utility model is that a fixing device of butterfly valve rod and valve clack is provided, it mainly includes valve rod (1), valve clack (2) and fixed pin (3), valve rod (1) is connected valve clack (2) position and is become the inclined plane 25 degrees with radial, valve clack (2) are connected valve rod position and are the round hole, fixed pin (3) are the inclined plane cylindric lock that has the boss, the inclined plane angle is 25 degrees, during the assembly, beat fixed pin (3) into the round hole of valve clack (2), and compress tightly with the inclined plane coincidence of valve rod (1); when the valve is disassembled, the fixing pin is taken out by utilizing the lug boss on the fixing pin (3), so that the valve rod (1) and the valve clack (2) are separated.
The utility model has the advantages that: after the butterfly valve is opened and closed for many times, the valve rod and the valve clack of the butterfly valve can still be connected and fastened.
