Structure of pneumatic butterfly valve damper:
The basic principles of both vehicle valves and industrial valves are almost the same. They are basically divided into two parts: a ball valve and a damping mechanism. The most essential part is rebound damping. It is also represented by R, and the said valve depends on this R to replace the energy+amount of impact. The higher compression damping is represented by C, and the higher compression damping is also divided into two sections, high speed compression C1 and low speed compression C2. For example, the pound number of the ball valve is fixed, and the curve of downforce travel and elasticity is fixed. To put it simply, the size of elasticity is fixed, At this moment, the compression damping C can be adjusted to restrain the reaction of stroke contraction and change the elastic curve. The low-grade vulgar compression damping C1 can reduce the interference of small vibration response to the valve when restraining the brake. The high-speed compression damping C2 can prevent the bottoming, which means that the stroke is exhausted, and it will not let the stroke run out, which is prone to danger, Or break the valve (increase the stroke to quickly shrink the end of the force).
Why can pneumatic butterfly valve replace pneumatic or hydraulic cylinder? Pneumatic butterfly valves have been widely used in many fields, even replacing traditional equipment in many industries. Today, let's take a look at why pneumatic butterfly valves can replace pneumatic or hydraulic cylinders.
The pneumatic butterfly valve can replace the pneumatic or hydraulic cylinder block because it has the following outstanding advantages: low preset height: compared with the traditional cylinder, the pneumatic butterfly valve has no piston rod, which can greatly reduce the preset height, making the structure more compact. Low purchase cost: compared with traditional cylinders, pneumatic butterfly valves not only have low purchase cost, but also need no maintenance due to the long life saving years of use, so the cost can be reduced. The installation is economical, simple and convenient: when the air is not inflated, the pneumatic butterfly valve is simple and sensitive to install, thus saving time and expense. And the product has good elasticity and can repay a small offset. Allowable horizontal injustice: the maximum horizontal injustice of pneumatic butterfly valve can reach 30mm, within which the reliability of work can still be maintained. Unlike the cylinder or hydraulic cylinder, the pneumatic cylinder has no tight sealing parts that will be jammed or worn, and does not need to install precise guiding devices that are susceptible to dust and other impurities. No friction=maintenance free: pneumatic butterfly valve can work effectively even under poor working conditions. Since there are no parts that rub against each other in the type cylinder, it will not wear even if it works in an environment with much dust, particles or sediment.
