Structural Characteristics of V-type Ball Valves


Release time:

Aug 12,2024

V-type ball valve is a compact structure regulating ball valve with 90°swing. Its structural feature is that the closing member is a V-type notched hemisphere, which can be fitted into the valve cavity from one side of the valve body, so that the valve body can be designed as an integral type. the upper and lower fixed shafts are inserted from both ends, and the head of the upper shaft is connected to the ball by a spline structure to transmit the operating torque.

   V-type ball valve is a compact structure regulating ball valve with 90°swing. Its structural feature is that the closing member is a V-type notched hemisphere, which can be fitted into the valve cavity from one side of the valve body, so that the valve body can be designed as an integral type. the upper and lower fixed shafts are inserted from both ends, and the head of the upper shaft is connected to the ball by a spline structure to transmit the operating torque. the sealing seat is hardened by overlaying cobalt-based alloy on the V-type ball body and machined into a sealing surface with the required accuracy. The movable metal seat on the valve body adopts the structure of seat with spring or plate spring loading. Due to the elastic restoring force of the spring/plate spring to push the seat, it can make a good sealing performance between the ball and the seat for a long time. meanwhile, because the valve seat adopts spring-loaded movable structure, it can make the valve seat automatically corrected to achieve the match with the ball spool, and the sealing performance is high.

    Main features of V-type ball valves.

1、Compact structure, small size, can be installed vertically and other advantages.

2, the maximum flow volume: because of its streamlined shape and full right-angle rotary control, so that the maximum value of the volume is particularly high, the flow capacity is particularly large, the flow resistance is small, so you can use smaller more economical and practical valve size.

3、V-type ball valve adopts double bearing structure, high mechanical stability performance, small starting torque, to ensure that the valve has excellent sensitivity and sensing speed.

4、Maximum reliability (safety): the valve body is a whole, strong and durable, the operation is not affected by pipeline pressure, and can avoid leakage of the valve body.

5、Superior sealing of metal seat: V type ball valve adopts movable metal seat, self-help compensation function, and has superior sealing performance and long service life.

6, strong shear capacity: V-ball valve with metal hard seal structure, V-ball valve core and metal valve seat in the rotary process, V-notch and the valve seat to produce a strong shear force can cut off fibers and other impurities, and has a self-cleaning function, to avoid the valve jamming phenomenon occurs. Particularly suitable for pipeline scaling frozen or containing fibers and particles of solid occasions.

     The structural design of V-ball valve makes it suitable for the occasions that need precise regulation and control of fluids. the V-opening design makes the valve have small flow resistance, suitable for high viscosity media and liquid-solid two-phase media, and also widely used in the chemical industry, petroleum, natural gas, electric power and other industrial fields, suitable for high temperature, high pressure, strong corrosive media control system.
