Description

Technical Field

[0001] The utility model relates to the technical field of clamping devices for processing and punching holes in stop valves, in particular to a clamping device for processing and punching holes in stop valves. Background Art

[0002] The stop valve, also known as the gate valve, is a forced sealing valve. Therefore, when the valve is closed, pressure must be applied to the valve disc to force the sealing surface to prevent leakage. When the medium enters the valve from under the valve disc, the resistance that the operating force needs to overcome is the friction between the valve stem and the packing and the thrust generated by the pressure of the medium. The force to close the valve is greater than the force to open the valve, so the diameter of the valve stem must be larger, otherwise the valve stem will bend. The corresponding mounting holes on the surface of the stop valve usually require the valve body to be clamped on the workbench of the drilling equipment for drilling. In today's life, stop valves are widely used, and stop valves are also used on the air conditioners we use in daily life.

[0003] However, the general punching clamping mechanism is clamped on one side, which greatly reduces the punching area and requires multiple adjustments to punch holes; therefore, we propose a clamping device for stop valve processing and punching to solve this problem. Utility Model Content
