Technical Field

[0001] The utility model relates to the technical field of valve gear boxes, in particular to a waterproof valve gear box. Background Art

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid conveying systems and have functions such as shut-off, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief. Valves used in fluid control systems, from the simplest shut-off valves to various valves used in extremely complex automatic control systems, have a wide variety of varieties and specifications. When operating the valve, a gear box is generally used to drive the valve to operate.

[0003] However, the existing processing equipment has the following shortcomings:

[0004] When using the device, after the user turns the handle to make adjustments, the handle is easily subjected to external force to rotate autonomously, causing fine adjustments to the inside of the main body, making it difficult to restrict the adjusted parts inside the device, resulting in the device being difficult to use; when using the device, the resistance plate is difficult to move, and the resistance plate is prone to reset when moving, causing the resistance plate and the resistance rod to move, making it difficult to restrict.

[0005] Therefore, we propose a waterproof valve gear box to solve the above problems. Utility Model Content

[0027] Specifically, one end of the support rod 67 is fixedly connected to a support plate 69 , and the surface of the rotating block 61 is fixedly connected to a connecting frame 68 .

[0028] In this embodiment, by providing a stopper rod 67 inside the rotating block 61, the stopper block 66 can be restricted, thereby reducing the possibility of the stopper block 66 floating up and down when the device is in use.
