Description

Technical Field

[0002] The small shaft drive is a remote drive device for operating valve parts, which can effectively solve the shortage of local operation space for valve parts in narrow spaces and achieve the purpose of remotely operating valve parts. Currently, as Figure 1 shown, the valve handwheel 01 needs to be connected to the round end joint 03 (type E1, CB / T 3791-1999), and then the drive pipe 5 is connected through the universal joint 4 to remotely transmit the opening and closing torque of the valve handwheel 01 to a place where personnel can easily operate.

[0003] The installation process of the round end joint 03 is complex. It is necessary to remove the valve handwheel 01, sleeve the locking nut at the bottom of the round end joint 03 onto the valve stem and then reinstall the handwheel. Use the groove of the round end joint body to clamp the three-point support of the valve handwheel, and finally install the round end body and the locking nut in place to achieve the connection between the round end joint and the valve handwheel.

[0004] Therefore, due to the structural limitation of the round end joint 03, the workload of disassembling the valve handwheel during its installation is relatively large.

[0005] In order to overcome the complexity and limitations in the installation process of the round end joint, this application proposes a small shaft drive end joint. This joint can not only eliminate the process of disassembling the valve handwheel, but its simple structural form can be applicable to various valve handwheels. Content of the Utility Model

[0009] One end of the end joint body facing the valve handwheel is fixedly provided with a circular mounting plate, and several connection hole groups are uniformly arranged along the circumferential direction on the circular mounting plate. Each connection hole group includes two connection holes;

[0010] The connection hole groups correspond to the U-shaped pipe clamps one by one, and the two connection holes in the connection hole group are adapted to the two legs of the U-shaped pipe clamp;

[0011] After the U-shaped pipe clamp passes through the corresponding support rod of the valve handwheel from below, the two legs of the U-shaped pipe clamp are inserted upward into the corresponding connection holes on the circular mounting plate and are fitted with mounting nuts to realize the connection between the end joint body and the valve handwheel.

[0012] Preferably, the distances from the centers of all the connection holes to the center of the circular mounting plate are all the same.

[0013] Preferably, the number of the U-shaped pipe clamps is the same as the number of the support rods in the valve handwheel.

[0014] Preferably, the distance between the two legs of the U-shaped pipe clamp is the same as the diameter of the support rod in the valve handwheel.

[0015] Preferably, one end of the end joint body away from the valve handwheel is connected to the transmission pipe through a universal joint.

[0016] Preferably, a bracket is rotatably fitted on the end joint body.

[0017] The beneficial effects of the utility model are as follows:

[0018] The structure of the utility model is simple and reliable, easy to manufacture, and can be widely applied to various types of valve handwheels.

Each connection hole group includes two connection holes;

[0034] The connection hole groups correspond to the U-shaped pipe clamps 3 one by one, and the two connection holes in the connection hole group are adapted to the two legs of the U-shaped pipe clamp 3;

[0035] After the U-shaped pipe clamp 3 passes through the corresponding support rod 02 of the valve handwheel 01 from below, the two legs of the U-shaped pipe clamp 3 are inserted upward into the corresponding connection holes on the circular mounting plate 101 and fitted with the mounting nut 2 to realize the connection between the end joint body 1 and the valve handwheel 02.
