The gas ball valve is a valve that uses a ball with a circular channel as the opening and closing part, and the ball rotates with the valve stem to realize the opening and closing action. It is suitable for frequent operation, opening and closing quickly and lightly. Fluid resistance is small. Simple structure, relatively small size, light weight, easy maintenance. Good sealing performance Not limited by the installation direction, the flow direction of the medium can be arbitrary. No vibration and low noise.
The main advantages of gas ball valve are as follows:
It is suitable for frequent operation, opening and closing quickly and lightly. Fluid resistance is small. Simple structure, relatively small size, light weight, easy maintenance. Good sealing performance Not limited by the installation direction, the flow direction of the medium can be arbitrary. No vibration and low noise.
The main disadvantages of gas ball valves are as follows:
The gas ball valve can be divided into: floating ball valve, fixed ball valve, elastic ball valve and oil-sealed ball valve according to the structure form; according to the channel, it can be divided into direct energy type, angle type and three-way type, etc., and the three-way type can be divided into T shape and L shape. two kinds. According to the connection method, it can be divided into three types: threaded connection, flange connection and welding type.
