Product Description
Overview
The eccentric ball valve is an advanced control valve with a right-angle rotation. Its opening and closing parts are hemispheres with special V-shaped openings and have sharp cutting edges. During the rotation of the ball, the sealing surface has a strong cutting force and self-cleaning function.
Working principle
The eccentric opening of the sphere and the valve seat flow channel form a fan-shaped area. The cross-sectional area of the flow channel can be changed during the rotation process to form a linear and proportional adjustment of the medium. Therefore, the V-type regulating ball valve has both functions of regulation and switch. It can be matched with pneumatic or electric actuators. It is commonly used in control systems in the fields of papermaking, chemical industry, petroleum, chemical fiber, electric power, metallurgy, pharmaceuticals, and environmental protection.
Features
1. The valve body is an integral design, which provides the valve body with higher strength, can withstand the pipeline pressure better, and avoids leakage from the shell;
2. The specially designed eccentric ball has a strong shearing effect and sealing performance on the medium, and the flow characteristics of the medium can be adjusted in proportion;
3. The surface of the sphere adopts hard chromium plating, nitriding, supersonic spraying and other sealing surface hardening processes to increase the hardness, wear resistance and corrosion resistance of the sealing surface.
4. The precision ground spherical surface reduces the friction between the sealing surfaces, thereby reducing the torque.
5. The special cover design without valve seat avoids the dead angle between the valve seat and the valve body that is easy to block, and avoids the situation of valve seat jamming.
6. Fixed ball valve structure, upper and lower double stems and double bearings fix the valve core, which has higher stability. The bearing is made of composite material and self-lubricating bearing with sintered bearing surface of the rotating bearing, which has very strong wear resistance. performance.
