Description

Technical Field

[0001] The present invention relates to the technical field of valve actuators, and in particular to a remotely controllable valve actuator. Background Art

[0002] A valve actuator is a device used to drive a valve. It uses electrical energy as its main energy source and realizes the rapid opening and closing of the valve through the work of the motor and the transmission mechanism. This device plays a key role in the automation control system. It receives signals from the regulator or computer (such as DCS, PLC, etc.) and adjusts the flow of the process medium according to its position and characteristics in the process pipeline, thereby controlling the controlled automation instrument within the range required by the production process. According to its working characteristics, the valve actuator can be divided into multi-turn, partial-turn, straight-through, angle-through and other types. It is suitable for different types of valves, such as regulating valves, gate valves, stop valves, butterfly valves, ball valves, plug valves, etc., to realize the remote centralized or individual control of industrial automation pipelines. Most of the existing valve actuators can only be operated and controlled on-site, and cannot be remotely controlled. The practicality is poor, and the valve actuator needs to be manually inspected using detection equipment after working for a long time to detect whether the internal structure of the valve actuator is damaged, which is inconvenient.

[0005] Preferably, the bottom of the fixed motor is fixedly connected to the upper surface of the valve actuator body, the outer surface of the telescopic cylinder passes through the rotating disk, and the telescopic cylinder is symmetrically arranged on both sides of the rotating shaft.

[0006] Preferably, the rotating ring is arranged directly below the rotating disk, and a first fixing plate and a second fixing plate are fixedly connected to sides of the lower surface of the rotating ring, and the first fixing plate is arranged opposite to the second fixing plate.

[0007] Preferably, the outer surface of the X-ray light source is fixedly connected to both sides of the first fixed plate, the outer surface of the data processing module is fixedly connected to the outer surface of the detector, and the outer surfaces of the detector and the data processing module are fixedly connected inside the second fixed plate.

[0008] Preferably, the end of the fixed sleeve is fixedly connected to the outer surface of the bracket, the outer surface of the fixed sleeve is sleeved with a movable sleeve, the internal thread of the movable sleeve is connected with a fixing screw, and the fixing screws are symmetrically arranged on both sides of the fixed sleeve.

[0009] Preferably, the outer surface of the movable sleeve is rotatably connected to a rotating member, the outer surface of the fixed clamp seat is fixedly connected to the outer surface of the rotating member, and the interior of the fixed clamp seat is fixedly connected to a fixed shaft.

[0010] Preferably, the interior of the movable clamp seat is rotatably connected to the outer surface of the fixed shaft, and the outer surface of the fixed shaft is sleeved with a return spring.

[0011] Preferably, the end of the return spring is fixedly connected to the inner surface of the fixed clamp seat, and the end of the return spring away from the fixed clamp seat is fixedly connected to the inner surface of the movable clamp seat.

[0012] Preferably, the valve actuator body, the fixed motor, the telescopic cylinder, the X-ray light source, the detector and the data processing module are all electrically connected to the remote control module.

[0013] The present invention provides a remotely controllable valve actuator, which has the following beneficial effects:

[0014] 1. The remotely controllable valve actuator is equipped with a controller, a sensor, an actuator and a communication module through a remote control module. With the cooperation of the remote control module, the staff can remotely control the opening and closing of the valve actuator body, and can also remotely control the detection device to detect the valve actuator body, making it more convenient for the staff to control the valve actuator, thereby improving the practicality and convenience of the valve actuator.

[0015] 2. The remotely controlled valve actuator uses X-rays to scan the valve actuator and obtain the internal structure of the valve actuator through a detection device, so as to determine whether the interior of the valve actuator is damaged, making it more convenient for staff to detect the valve actuator. Under the drive of a fixed motor and a telescopic cylinder, the valve actuator can be scanned and detected at different positions to obtain more comprehensive internal information of the valve actuator, thereby improving the accuracy of the detection.

[0016] 3. The remotely controllable valve actuator uses a supporting device. Since the existing valve actuator is directly installed on the pipeline and relies on the pipeline to support it, when the valve actuator is subjected to external forces, the pipeline is easily damaged. The supporting device can provide additional supporting force for the valve actuator to disperse the forces exerted on the pipeline and improve the stability of the valve actuator installation. When the valve actuator is subjected to external forces, the external forces exert a smaller force on the pipeline, thereby preventing the pipeline from being damaged, thereby improving the protection of the valve actuator and the pipeline connected thereto.
