The parameters of pressure balanced double rod floating ball valve are as follows: (1) pressure 0-1.6mpa; (2) temperature 0-80 ° (3) medium: water. (4) Connection mode: external thread.
Application: the ball valve is suitable for water storage tank. The buoyancy and weight of the ball are used to keep the water level in the tank stable.
Action principle: the valve rod is used to connect the valve seat disc and the cylinder gasket guide piece with the same diameter of the valve seat; the water supply pressure is evenly distributed in the valve body, and the "lifting force (valve closing direction)" is applied to the upper part of the valve seat disc respectively, and the "lifting force (valve closing direction)" is applied to the lower part of the cylinder gasket guide piece. The opening pressure (pressure drop force) applied inside the valve body is equal to the closing pressure (lifting force). Therefore, even if a small floating ball is used, the valve can be closed reliably.
pressure balanced double rod floating ball valve characteristics:
1) FW type floating ball valve is equipped with water level regulating bolts, which can adjust water level easily when necessary.
2) FW type float valve adopts built-in filter, which can effectively prevent foreign matters from sticking on the valve seat.
3) FW type floating ball valve can be equipped with water wave prevention pipe (length: 125625mm), which is better than the old type water wave prevention plate
Water wave prevention effect.
4) As an important part of the solution to water rust, CAC 406 (= bronze) or stainless steel is used in the main waterway quality.
5) The pressure balance mechanism has excellent effect on preventing vibration and water hammer.
