Description

Technical Field

[0001] The utility model relates to the technical field of valve fixing, in particular to a valve clamping device. Background Art

[0002] Coal mine comprehensive mining hydraulic support structure control valves mainly include safety valves, hydraulically controlled one-way valves, operating valves and other types. These valves play a key role in the hydraulic support structure system to ensure the normal operation and safety of the hydraulic support structure. The coal mine comprehensive mining hydraulic support structure control valve is a complex system used to ensure the safe, stable and efficient operation of the hydraulic support structure. After the valve body casting is produced and formed, it is necessary to drill or tap the end opening. In order to ensure the stability of the valve during the processing, it is often necessary to place the valve on a clamping device to clamp and fix it, so as to improve the stability of the valve and the processing efficiency. The valve clamping device commonly used on the market for coal mine comprehensive mining hydraulic support structure control valves has limited fixing effect on the bottom of the valve during the fixing process. If it encounters a collision, it is very easy to slide and tilt slightly, affecting the processing efficiency. In addition, the clamping device can only be used to process and fix the coal mine comprehensive mining hydraulic support structure control valve. The fixed valve model is relatively single and its use is limited. Utility Model Content
