The ball of the ball valve is elastic. Both the ball and the valve seat sealing ring are made of metal materials, and the sealing specific pressure is very large. The pressure of the medium itself cannot meet the sealing requirements, and external force must be applied. This valve is suitable for high temperature and high pressure medium.
The elastic sphere is obtained by opening an elastic groove at the lower end of the inner wall of the sphere to obtain elasticity. When the channel is closed, the wedge head of the valve stem is used to expand the ball and compress the valve seat to achieve sealing. Before turning the ball, loosen the wedge head, and the ball will return to its original shape, so that there is a small gap between the ball and the valve seat, which can reduce the friction and operating torque of the sealing surface.
Qv347, Qv647, Qv947 V-type regulating ball valve
Qv347, Qv647, Qv947 V-type regulating ball valve has a shearing effect on the valve seat due to the V-shaped structure of the ball core. Therefore, it is suitable for the control of relevant process parameters in the suspension medium containing fibers or tiny solid particles in papermaking, chemical, metallurgical and other industrial enterprises, especially for pulp, white water, black liquor, white Automatic adjustment of fluids of suspended particles such as liquids and thick and turbid slurry fluids.
This V-shaped ball valve is a fixed ball valve, and it is also a single-seat sealed ball valve. The adjustment performance is the best in the ball valve, the flow characteristics are equal percentages, and the adjustable ratio is up to 100:1. It has a shearing effect between its V-shaped notch and the metal valve seat, which is especially suitable for media containing fibers, tiny solid particles, and slurry.
Three-way ball valve has T type and L type. The T type can connect three orthogonal pipes to each other and cut off the third channel, and play the role of diversion and confluence. The L type can only connect two pipes that are orthogonal to each other, and cannot keep the third pipe connected to each other at the same time, and only plays the role of distribution.
