V-ball valve structure:

The ball core of v-ball valve has V-shaped structure, the valve core is 1 / 4 ball shell, with V-shaped notch, large circulation capacity, large adjustable range, shear force, tight closing, etc., which is especially suitable for the working condition of fluid material with fibrous shape. Generally, v-ball valves are single seal ball valves. Not suitable for two-way use.

V-ball valve principle:

V-shaped edge, cut off impurities. In the process of ball rotation, the v-knife edge of the ball is tangent to the valve seat, so as to cut off the fibers and solid substances in the fluid, while the general ball valve does not have this function, so it is easy to cause fiber impurities to jam when it is closed, which brings great inconvenience to maintenance and repair. The valve core of v-ball valve will not be stuck by fiber. In addition, due to the use of flange connection, it is easy to disassemble, without special tools, and easy to maintain. When the valve is closed. V-notch and valve seat produce wedge-shaped scissor action, which not only has self-cleaning function but also prevents the ball core from being stuck. The valve body, bonnet and valve seat adopt metal point-to-point structure respectively. In addition, the valve stem spring with small friction coefficient is used, so the operating torque is small and stable.

The edge of the valve core is V-shaped, and there is a V-shaped opening on the ball. With the rotation of the ball, the flow can be adjusted by the change of the middle opening area, and the impurities in the fluid can be cut off and closed, which is suitable for the control of pulp, mortar and viscous fluid.
