The operation-related matters of different types of stainless steel flanged ball valves are also different. Today, the main introduction is the operation instructions of stainless steel three-piece flanged ball valves.
When operating the stainless steel three-piece flanged ball valve, there are two operating modes, one is to open and the other is to close.
Before the stainless steel three-piece flanged ball valve is opened, the ball will be tightly pressed on the valve seat under the action of the mechanical pressure of the valve stem. When the stainless steel three-piece flanged ball valve is rotated counterclockwise, the valve stem will move clockwise, and the angular plane at the bottom will allow the ball to move away from the valve seat.
When the valve stem continues to lift, it will act as a guide pin in the spiral groove of the valve stem. At this time, the ball will start to rotate without friction.
Until the fully open position, the valve stem of the stainless steel three-piece flanged ball valve will be lifted to the high position, and the ball will be rotated to the fully open position.
In the process of closing, its operating principle is the opposite of that of opening. When the sphere is tightly pressed on the seat, the sealing state can be achieved.
