Thermal insulation V-shaped ball valve, V-shaped ball valve, ball valve

Product Overview of the Thermal Insulation V-Type Ball Valve:

The thermal insulation V-type ball valve adopts an integral jacket structure design, which can provide more uniform insulation and cold preservation. The V-type ball valve is smaller in volume and lighter in weight compared to ordinary ball valves, and it has no external leakage. It has excellent sealing performance. The jacket is made of carbon steel pipe welding, which is more pressure-resistant and firm than castings. The jacket, valve body outer side, and jacket connection pipe are welded together. The maximum pressure allowed for steam or cold water is 1 MPa. The V-type ball valve is a straight-angle rotating advanced control valve. Its closing element is a semi-spherical body with a special V-shaped opening, featuring sharp edges. During the rotation of the ball, the sealing surfaces have strong cutting force and self-cleaning functions. The V-shaped opening of the ball body forms a fan-shaped area with the valve seat flow channel, which can change the cross-sectional area of the flow channel during rotation, achieving linear and proportional precise regulation of the medium. Therefore, the V-type ball valve has both regulating and switching functions and can be used in conjunction with pneumatic or electric actuators, and is widely used in control systems in fields such as papermaking, chemical industry, petroleum, chemical fiber, power, metallurgy, pharmaceuticals, and environmental protection. 

Advantages of the insulated V-type ball valve product:

1. Valve body:

(a) Integrated design provides higher strength for the valve body, enabling it to better withstand pipeline pressure.

(b) Avoids leakage caused by the flange connection of the two-piece valve body.

(c) Features both flange and clamp connection structures.

2. Valve core:

(a) Special V-shaped ball design provides strong shearing effect and sealing performance for the medium, achieving proportional regulation of the medium's flow characteristics.

(b) Can be treated with hard chrome plating, ion nitriding, or supersonic spraying to increase the hardness, wear resistance, and corrosion resistance of the sealing surface.

(c) The precision-ground spherical surface reduces friction between the sealing surfaces, thereby reducing torque.

3. Valve seat:

(a) Special no-valve-seat-cover design avoids the formation of easily clogged dead corners between the valve seat and the valve body, preventing the valve seat from getting stuck.

(b) The valve seat spring adopts a snap ring design, providing preload force for the valve seat seal while significantly reducing the torque required to operate the valve.

(c) The valve seat with preload force can provide good sealing even under a small pressure difference.

4. Valve stem:

(a) Fixed ball valve structure, with upper and lower double valve stems and double bearings for fixing the valve core, providing higher stability. The bearings are composite materials, and the rotating shaft bearing surface is sintered for self-lubrication, with extremely strong wear resistance. It reduces torque and avoids valve stem jamming over long-term use.

The jacket is made of carbon steel pipe welding, which is more pressure-resistant and firm than castings. The jacket, valve body outer side, and jacket connection pipe are welded together. The maximum pressure allowed for steam or cold water is 1 MPa. The insulated V-type ball valve is a high-grade control valve with a right-angle rotation. Its closure element is a semi-sphere with a special V-shaped opening, featuring sharp edges. During the rotation of the ball, the sealing surfaces have strong cutting force and self-cleaning functions. The V-shaped opening of the ball and the valve seat flow channel form a fan-shaped area. During the rotation process, the cross-sectional area of the flow channel can be changed, forming a linear and proportional precise regulation of the medium. Therefore, the insulated V-type ball valve has both regulation and opening functions and can be used in conjunction with pneumatic or electric actuators, and is widely used in control systems in fields such as papermaking, chemical industry, petroleum, chemical fiber, power, metallurgy, pharmaceuticals, and environmental protection.
