Structure and principle of V-type ball valve

V-type ball valve structure
The ball core of the V-type ball valve has a V-shaped structure. The valve core is a 1/4 spherical shell with a V-shaped notch. It has large flow capacity, a large adjustable range, shear force, and can be closed tightly. It is particularly suitable for working conditions where the fluid material is fibrous. In general, V-type ball valves are single-seal ball valves. Not suitable for two-way use.

The edge of the valve core is V-shaped, and there is a V-shaped opening on the ball. As the ball rotates, the flow rate can be adjusted by changing the middle opening area, and the impurities mixed in the fluid can be cut off and closed. It is suitable for the control of pulp, mortar, and viscous fluids.

V-type ball valve principle
V-shaped edge, cut off impurities. During the rotation of the ball, the V-shaped blade of the ball is tangent to the valve seat, thereby cutting off the fibers and solid substances in the fluid. The general ball valve does not have this function, so it is easy to cause the fiber impurities to get stuck when closing, which brings great inconvenience to repair and maintenance. The valve core of the V-type ball valve will not be stuck by the fiber. In addition, due to the flange connection, it is easy to disassemble and assemble, no special tools are required, and maintenance is also simple and easy. When the valve is closed, a wedge-shaped scissor effect is generated between the V-shaped notch and the valve seat, which has both self-cleaning function and can prevent the ball core from getting stuck. The valve body, valve cover and valve seat are respectively made of metal point-to-point structure, and a valve stem spring with a small friction coefficient is used. Therefore, the operating torque is small and very stable.
