The effect of active control of body balance is poor. Subsequently, the pneumatic butterfly valve became an option for all 1958 Cadillac vehicles. As pneumatic butterfly valves are more and more widely used, some customers complain that the ball valves they have used have quality problems and are often crushed. However, the bomb of Shanghai Dongfeng
The spring will not have quality problems. Now, Shanghai Dongfeng will give you an answer to the problems that may arise in the process of using pneumatic butterfly valves.
1. The purpose of ball valve strength calculation is to ensure that the ball valve does not appear plastic deformation and fatigue damage during operation; The purpose of ball valve stiffness calculation is to ensure that the ball valve has the required flexibility.
2. The relationship curve between the load on the ball valve and its deformation is called the ball valve performance curve. The slope value of the performance curve reflects the stiffness of the ball valve. The performance curve of constant stiffness ball valve is a straight line, while that of variable stiffness ball valve is a curve.
3. The strength of the ball valve is independent of the effective number of turns n, and the stiffness of the ball valve is inversely proportional to the effective number of turns n.
Pneumatic butterfly valves are used in industrial equipment. Pneumatic butterfly valve technology is applied to the valves of industrial equipment, which effectively improves the working efficiency of equipment and the safe service life of equipment. Shanghai Dongfeng pneumatic butterfly valve does not have an internal control rod, piston or sliding sealing device like the ordinary cylinder device, which greatly reduces the cost of using pneumatic or hydraulic cylinders and wins more economic benefits for customers.
The dot is:
Low cost and wide range of specifications
Long service life, no need for maintenance and lubrication, no need for internal lever or piston
Soft medium without friction effect
Bending capacity, side load capacity, compact original height pneumatic butterfly valve? Pneumatic butterfly valve, pneumatic butterfly valve, pneumatic butterfly valve, etc.
Features of pneumatic butterfly valve, The stiffness of the pneumatic butterfly valve changes with the load, which makes the ball valve device have an ideal performance: the pneumatic butterfly valve can bear axial and radial loads at the same time, and can also transmit torque. The pneumatic butterfly valve can obtain different bearing capacity by adjusting the internal pressure, so it can meet the needs of a variety of loads: the pneumatic butterfly valve has light weight, long service life, and good high-frequency vibration isolation and sound insulation performance. Pneumatic butterfly valve requires small installation space and is easy to replace.
