Pneumatic stainless steel V-shaped regulating pinch ball valve is composed of two parts: pneumatic piston actuator and V-shaped ball valve. Pneumatic piston actuators are divided into two types: single acting and double acting. There are two sealing forms for V-shaped ball valves: soft seal and hard seal.
(Front) Pneumatic V-shaped ball valve A. When the pneumatic piston actuator is double acting:
The gas source signal pressure output by the double acting locator is respectively input into the left and right air chambers of the actuator piston. Due to the different pressure of the air source in the left and right chambers of the input piston, a pressure difference is formed, which drives the piston to move in a straight line. Through gear rack transmission, the linear motion of the piston is converted into the rotational motion of the actuator spindle until the pressure in the left and right chambers is balanced and stops moving. When the actuator rotates, it drives the valve stem and valve core to rotate, changing the flow area between the valve core and valve seat to achieve the purpose of regulation.
b. When the pneumatic piston actuator is single acting:
The gas signal pressure output by the single acting locator is input into the actuator's non spring side chamber. The difference between the thrust and spring force formed by the gas signal pressure acting on the piston causes the cylinder piston to move linearly. Driven by gears and racks. Until the thrust generated by the air signal pressure balances with the spring force, the motion stops. When the actuator spindle rotates, it drives the valve stem and valve core to rotate, thereby changing the flow area between the valve core and valve seat, achieving the purpose of regulation.
The pneumatic V-shaped regulating ball valve is composed of a V-shaped valve body, ZSQ pneumatic actuator, and other accessories. It is a high-end regulating valve with a right angle rotary structure. The V-shaped ball valve requires no maintenance for a long time and has a long service life, providing you with a truly efficient valve for controlling process conditions.
The V-shaped ball valve has excellent regulating characteristics, with approximately equal percentage flow characteristics and an adjustable ratio of up to 300:1. Therefore, V-shaped ball valves can provide precise control over a wide range of variations.
Pneumatic V-shaped regulating ball valve is used in conjunction with valve positioner to achieve proportional adjustment, and is used in conjunction with a two position five way solenoid valve and control box to achieve switch control, It has precise interception performance and control function, suitable for various control occasions, with advantages such as high rated flow coefficient, large adjustable ratio, excellent sealing performance, compact structure, small volume, vertical and horizontal installation, and is suitable for controlling gas, liquid, and solid granular media. Due to the lack of clearance between the valve core and valve seat, it has great shear force and self-cleaning performance, especially suitable for suspensions and solids containing fibrous or small solid particles. Particle control. Therefore, this product is widely used in industries such as petroleum, chemical, power, papermaking, metallurgy, etc.
The maximum flow rate, due to its streamlined line and full right angle rotation control, is particularly high, with a large flow capacity and low flow resistance, making it possible to use smaller and more economical valve sizes.
The V-shaped ball valve adopts a double bearing structure, which has high mechanical stability and small starting torque, ensuring that the valve has good sensitivity and sensing speed.
Maximum reliability (safety), the valve body is an integral structure, sturdy and durable, and its operation is not affected by pipeline pressure, which can avoid valve body leakage.
The metal valve seat has superior sealing performance. The V-shaped valve adopts a movable metal valve seat with self compensating function, superior sealing performance, and long service life.
Super strong shear capacity, the V-shaped ball valve adopts a metal hard seal structure. During the rotation of the V-shaped valve core and metal valve seat, the V-shaped groove and valve seat generate strong shear force, cutting off impurities and other fibers, and has self-cleaning function to avoid valve jamming.
