The utility model relates to an actuator connecting device of a new valve, which belongs to the technical field of the connecting device of the valve actuator.
Invention Background The executing agency uses liquids, gases, electricity or other energy sources and converts them to a driving function by means of motors, cylinders or other devices. The basic actuator is used to drive the valve to full open or closed position. The actuator with the control valve is able to accurately move the valve to any position.
Although most actuators are used for switching valves, but today's actuators are designed far beyond simple switching functions, including position sensors, torque sensors, electrode protectors, logic controllers, digital communication modules and PID control modules, all of which are installed in a compact enclosure.
The existing technology in the upper and lower connectors do not have a disc spring, so that the actuator closed when the valve shut down when the hard connection caused by the closure of the seal surface damage, bite Deng situation.
In view of the shortcomings of the existing technology, the utility model aims to provide a new type of valve actuator connecting device to solve the problem. In order to achieve the above purpose, the utility model is realized by the following technical scheme: The utility model relates to a new actuator connecting device of the valve, comprising a lower connecting piece, a bolt, a cover plate, an upper connecting part, a disc spring, and the upper connecting part is connected by a thread connecting the lower connecting part through a bolt, and the cover plate is connected with the lower connecting part by a bolt The disc spring is connected with the lower connecting piece through the upper connecting piece, and the lower connecting piece is composed of a left threaded hole, the countersunk head hole, the right threaded hole, the lower connecting piece through hole and the lower connecting piece sleeve are composed, the left threaded hole is fixedly connected with the lower connecting part, the sinking head hole is located in the middle of the lower connecting part, the right threaded hole and the lower connecting piece are fixedly connected,
The lower connector sleeve is fixedly connected with the lower connecting part through the hole. Further, the cover plate is composed of a fixed hole and an inner circular hole. An internal thread is arranged inside the fixing hole. The upper connecting part is composed of an upper connecting piece through hole and an upper connecting part sleeve. The upper connecting piece through-hole edge is provided with a chamfering angle. The outer diameter of the upper connector is less than 4mm of the inner diameter of the lower connecting part.
The disc spring has large stiffness and strong cushioning ability, and can withstand large loads with small deformation. The utility model discloses a new valve actuator connecting device, the structure is arranged between the upper connecting piece and the lower connecting piece to install a disc spring, so that the closing force of the actuator is increased flexibly when the valve closes, and the sealing surface is damaged and the Deng condition is not caused by the close of the hard connection.
