Description of content
The utility model is a novel valve actuator connecting device belonging to the technical field of valve actuator connecting device.
Background of the Invention
Actuators use liquid, gas, electricity or other energy sources and convert them into drive action through motors, cylinders or other devices. The basic actuator is used to drive the valve to the fully open or fully closed position. Actuating and control valve actuators enable precise positioning of the valve to any position. Although most actuators are used for on-off valves, today's actuators are designed to go beyond the simple switching functions of position sensing, torque sensing, electrode protection, logic control, digital communication modules And PID control module, etc., and these devices are all installed in a compact housing.
In the prior art, there is no disc spring on the upper connecting piece and the lower connecting piece, so that when the closing force of the closing valve is shut off due to the hard closing of the valve, the sealing surface is damaged and killed.
Content of the invention
In view of the shortcomings of the prior art, the purpose of the utility model is to provide a novel valve actuator connecting device to solve.
In order to achieve the above object, the present invention is achieved by the following technical solutions: A novel valve actuator connection device, the structure of which comprises a lower connector, a bolt, a cover plate, an upper connector and a disc spring, wherein the upper connector Piece is screwed with the lower connecting piece through a bolt, the cover plate is screwed with the lower connecting piece through a bolt, the disc spring is movably connected with the lower connecting piece through an upper connecting piece, the lower connecting piece is composed of a left-handed screw hole and a countersunk head Hole, a right threaded hole, a lower connecting piece through hole and a lower connecting piece sleeve, wherein the left threaded hole is fixedly connected with the lower connecting piece, the counterbore hole is located in the middle of the lower connecting piece, the right threaded hole is connected with the lower The connecting piece is fixedly connected, and the lower connecting piece sleeve is fixedly connected with the through hole of the lower connecting piece.
The utility model is a new type of valve actuators implementing agencies connected device schematic cross-sectional structure

Further, the cover plate is composed of a fixing hole and an inner circular hole. The fixing hole is internally provided with an internal thread. The upper connecting piece is composed of an upper connecting piece through hole and an upper connecting piece sleeve. The edge of the through hole of the upper connector is provided with a chamfer. The outer diameter of the upper connector is smaller than the inner diameter of the lower connector by 4 mm. The rigidity of the disc spring is large, the buffering vibration absorbing ability is strong, and can bear large loads with small deformation.
The utility model is a novel valve actuator connecting device, the structure is installed between the upper connector and the lower connector disc spring, so that the actuator closing force when the valve is closed to increase the flexibility will not be hard to connect Close too fast and cause sealing surface damage, seizures and so on.
