The characteristic of the V-shaped ball valve is that its ball center is designed with a scissors-type "V"-shaped notch, which has a strong shearing force, especially for some stubbornness, which can be effectively restrained and cut off to ensure that when encountering special media For normal operation, such a design is not only a working feature, but also reserves a lot of space for later maintenance.
The V-type ball valve adopts a cylindrical spring preloaded structure with a compensating movable metal seat, the ball core and the valve seat will not be blocked or separated, and the service life is long. There is a shearing effect between the V-shaped notch on the ball core and the metal valve seat, which is especially suitable for controlling media with high viscosity, containing fibers, solid particles and pulp. It can be used for switch, cut off and adjustment on the pipeline. The working principle of V-type ball valve is to use the top actuator (handle, turbine, pneumatic, electric) actuator to drive the valve stem, and drive the ball center to rotate at a right angle of 90° to switch or adjust the opening of the ball valve. That is to say, the choice of drive determines the usage occasion.
V-type ball valve adopts movable metal seat, self-compensation function, and has excellent sealing performance. In the flow direction, the leakage is rated for the flow coefficient. The V-shaped ball valve adopts a metal hard sealing structure. During the rotation process of the ball center and the metal valve seat, the V-shaped notch and the valve seat generate a strong shearing force. The super shear strength can cut off impurities such as fibers, and has a self-cleaning function to avoid valve jamming.
(1) Handle operation, through the handle on the top, twisting in a right-angle direction drives the ball center of the valve stem to rotate back and forth at a right angle of 90°. This handle driving method can only be used for opening or closing or cutting off the ball valve.
(2) Turbine operation, through the top turbine transmission mechanism, the rotation of the handwheel in the (clockwise, counterclockwise) direction drives the valve ball rod back and forth at a right angle of 90°. This turbine drive method can be used for low precision. Adjust the occasion.
(3) Pneumatic operation, through the top pneumatic actuator, using compressed air as power, through matching with solenoid valve and positioner, driving the valve stem to drive the ball center to rotate back and forth at a right angle of 90°, pneumatic operation is mainly used for high-precision cutting, Adjust the occasion.
(4) Electric operation, the V-shaped ball valve is powered by 220V and 380V power supply through the electric actuator on the top, and the valve stem is driven by the built-in servo module to drive the ball center to rotate back and forth at a right angle of 90°. Electric operation is mainly used for high-precision cutting and adjustment occasions.
