Flange ball valve structure principle use principle introduction

The valve body is integral or combined and has the same 90-degree rotational operation. Its circular through hole and passage can pass directly through the axis. When the ball valve is rotated 90 degrees, it is basically presented at the inlet or the outlet. Spherical so that it can be used to cut off the flow.
When starting the valve, only the gas needs to be rotated by 90 degrees, so that there will be a small turning torque to achieve the possibility of tight closing. The valve body cavity of the same DC channel has a small increase in resistance to liquid.
Slice ball valve
Do not think that the ball valve can only be used for opening and closing. The truth is not true. The electric flange ball valve is not a traditional wide-type valve. It can realize safety throttling and flow control functions. At the same time, the structure is compact, easy to disassemble and maintain, and suitable. The ball valve for water and electric flanges has the same 90 degree lift action and has a circular through hole or passage through its axis. The ratio of the spherical surface to the passage opening should be such that when the ball is rotated 90 degrees, the spherical surface should be entirely present at the inlet and outlet to intercept the flow.
The ball valve only needs to be rotated 90 degrees with a small rotation torque to close tight. The fully equal valve body cavity provides a small, straight-through flow path for the medium. In the past, it was always thought that the ball valve was the most suitable for opening and closing directly, but modern ball valve function has been used as throttling and flow control. The electric flanged ball valve is compact in design, easy to disassemble for repair and maintenance, and can be used for working media in water and natural gas and in harsh conditions.
