Description

Quick coupling device for valve actuator Technical Field The utility model relates to the field of valve actuators, in particular to a quick coupling device for a valve actuator. Background A valve is a fluid control device that is used to control the flow, pressure, direction and operating state of a fluid in a conduit. The actuator is a mechanism device that converts signals, energy, etc. into valve motion. According to different control requirements, different actuating mechanisms can be selected, such as a pneumatic actuating mechanism, a hydraulic actuating mechanism, an electric actuating mechanism and the like, chinese patent discloses a quick coupling joint (grant bulletin number CN 205806653U) of a switch valve and a straight travel actuator, concentricity of an actuator push rod and a valve rod of the valve is guaranteed when the technology is connected and installed, the problem that rod pieces on two sides of the actuator and the valve are not concentric due to machining and installation errors can be solved to a certain extent, bending of the rod piece on one side is avoided, smooth switching of the valve is ensured, the service life of the rod piece is prolonged, but the design is fixed through a locking screw, the valve breaks threads on the valve rod and the actuator push rod in the opening and closing process, so that the locking screw is loosened, and detachment is caused. Accordingly, one skilled in the art would be able to provide a valve actuator quick coupling that addresses the problems set forth in the background above. Disclosure of utility model In order to solve the technical problems, the utility model provides a quick connecting device for a valve actuator, which comprises the actuator, positioning pins, elastic snap springs, a valve and a flange plate, wherein four positioning pins with the same size are arranged on the side wall of the bottom of the actuator, the positioning pins can be clamped into the flange plate, the lower end surface of the actuator is tightly attached to the upper end surface of the flange plate, the flange plate is arranged on the upper side of the valve, and the elastic snap springs are arranged at the lower end positions of the positioning pins clamped into the flange plate. Preferably, the outer side wall of the bottom end of the positioning pin shaft is provided with a positioning pin groove; Preferably, the flange plate is provided with four mounting holes with the same size, and positioning pins can be arranged in the mounting holes; Preferably, when the positioning pin shaft is clamped into the mounting hole, the positioning pin groove is arranged at the lower position of the lower end surface of the flange plate, and the positioning pin groove can be clamped into the mounting elastic clamp spring. The utility model has the technical effects and advantages that: 1. Four positioning pins are arranged below the actuator, the positioning pins are arranged in corresponding mounting holes of the flange plate, the lower end face of the actuator is made to be tightly attached to the upper end face of the flange plate, at the moment, the positioning pin grooves are arranged at the lower position of the lower end face of the flange plate, the elastic snap springs are compressed and are arranged in the positioning pin grooves of the positioning pins, the elastic snap springs are loosened and clamped into the positioning pin grooves, and the actuator is automatically fixed and locked to be connected with the valve; 2. the quick assembly disassembly is convenient, and the quick construction is convenient.
