[0002] The valve seat is a detachable surface part in the valve, which is used to support the fully closed position of the valve core and form a sealing pair. Generally, the valve seat diameter is the maximum flow diameter of the valve. For example, the valve seat material of the butterfly valve is very wide, and various types of rubber, plastic, and metal materials can be used as valve seat materials; and the sealing ring ensures the sealing of the entire valve. After the valve seat and sealing ring are produced, they need to be assembled to use the processing platform.

[0003] When the device is in use, it is usually necessary to manually operate the installation of the valve ring. At this time, it is necessary to compare the parallel state between the valve ring and the valve seat. This method is also prone to errors. In addition, the assembly procedure is too complicated and requires high manpower, which is inconvenient to use and increases labor costs. Therefore, it is necessary to design valve seat ring processing tooling. Utility Model Content

[0012] 1. The utility model is provided with a motor body, a transverse extension plate, a valve ring seat, a valve ring placement plate, a return spring, a rotating column, a rotating ring, a pressing rod and a pressing processing component. When the device is used, the staff first places the valve ring on the upper surface of the valve ring placement plate, and then starts the motor body to make the rotating gear rotate clockwise. Then the rotation of the rotating gear drives the meshing plate to move in the opposite direction. In this process, the rotating rod encounters the obstruction of the gear lever. Under the setting of the rotating column and the rotating ring, the valve ring seat is turned 180 degrees, and the valve ring seat and the valve seat plate overlap. At this time, the pressing rod on one side of the transverse extension plate contacts the external switch, so that the pressing processing component starts to press down. The downward pressure of the pressing processing component presses the valve ring placement plate. At this time, the valve ring placement plate brings the valve ring out and presses and assembles with the valve seat. Then, under the action of the return spring, the valve ring placement plate returns to its original position, so that the valve ring does not need to compare the position when it is pressed down and docked with the valve seat.

[0013] 2. The utility model provides a pressing rod. When the device is in use, after the rotating gear starts working, it drives the pressing rod on one side of the transverse extension plate to move toward the direction of the external switch. Because it is in a calm state with the external switch, when it reaches the designated location, it will start the processing component, thereby achieving the purpose of full automation of the device.
