What are the differences between O-shaped ball valves and V-shaped ball valves?
Ball valve structure
There are many types of structures for ball valves, but they are basically the same. They are all round ball cores with opening and closing parts, mainly composed of valve seats, balls, sealing rings, valve stems, and other driving devices. The valve can be opened and closed by rotating the valve stem 90 degrees. They are used in pipelines to shut off, distribute, regulate flow, and change the flow direction of the medium. The valve seat uses different sealing forms according to different working conditions. The valve body of the O-ring ball valve is equipped with a ball with an intermediate through-hole inside. There is a through-hole with a diameter equal to the pipeline diameter on the ball, which can rotate in the sealing seat. There are circular elastomers on both sides of the pipeline direction to achieve sealing. The V-shaped ball valve core has a V-shaped structure, and the valve core is a 1/4 ball shell with a V-shaped notch. It has a large flow capacity, a large adjustable range, shear force, and can be tightly closed, making it particularly suitable for fluid materials with fibrous structures.
O-type ball valve structure:
The valve body of the O-ring ball valve is equipped with a ball with an intermediate through-hole inside. There is a through-hole with a diameter equal to the pipeline diameter on the ball, which can rotate in the sealing seat. There are circular elastomers on both sides of the pipeline direction to achieve sealing. By rotating the ball by 90 °, the direction of the through-hole can be changed, thereby achieving the opening and closing of the ball valve. The O-type ball valve adopts a floating or fixed design, and the relative moving parts are made of self-lubricating materials with minimal friction coefficient, resulting in low operating torque. In addition, the long-term sealing of sealing grease makes operation more flexible. Its product advantages are as follows:
1. O-type ball valve has low fluid resistance
V-shaped ball valve structure:
The V-shaped ball valve core has a V-shaped structure, and the valve core is a 1/4 ball shell with a V-shaped notch. It has a large flow capacity, a large adjustable range, shear force, and can be tightly closed, making it particularly suitable for fluid materials with fibrous structures. Generally, V-shaped ball valves are single sealed ball valves. Not suitable for bi-directional use.
V-shaped edge, cutting off impurities. During the rotation of the ball, the V-shaped blade of the ball is tangent to the valve seat, thereby cutting off fibers and solid substances in the fluid. However, ordinary ball valves do not have this function, which can easily cause fiber impurities to get stuck when closing, causing great inconvenience to maintenance and repair. The valve core of the V-shaped ball valve will not be stuck by fibers. In addition, due to the use of flange connection, its disassembly and assembly are simple, without the need for special tools, and maintenance is also simple and easy. When the valve is closed. The V-shaped notch produces a wedge-shaped scissors effect between the valve seat, which has self-cleaning function and can prevent the ball core from getting stuck. The valve body, valve cover, and valve seat respectively adopt a metal point-to-point structure, and a valve stem spring with a small friction coefficient is used. Therefore, the operating torque is small and very stable.
V-shaped ball valve is a right angle rotating structure that can achieve flow regulation. It can achieve different degrees of proportionality according to the V-shaped angle of the V-shaped ball. V-shaped ball valves are generally used in conjunction with valve actuators and locators to achieve proportional adjustment. V-shaped valve cores are most suitable for various adjustment occasions, with high rated flow coefficient, large adjustable ratio, good sealing effect, zero sensitivity in adjustment performance, small volume, and can be installed vertically or horizontally. Suitable for controlling media such as gases, vapors, liquids, etc. The V-shaped ball valve is a right angle rotary structure, composed of a V-shaped valve body, pneumatic actuator, locator, and other accessories; There is an approximate inherent flow characteristic of equal percentage; Adopting a dual bearing structure, with low starting torque, excellent sensitivity and sensing speed, and strong shear ability.
