What are the skills for matching pneumatic butterfly valves?
There are some tips for stopping the modification of pneumatic butterfly valve, which are explained below:
1、 Whether the upper and lower joint sleeves of pneumatic butterfly valves can be high-strength polyurethane sleeves is also an important basis for ensuring long-term high-strength use. Because ordinary rubber is difficult to use for a long time under high strength.
2、 Check whether the product can provide a 2-3 inch lift request. Some products only provide a 2 inch lift. It is easy to pull to the limit in off-road to cause damage after barely using the 3 inch lift.
3、 Whether the diameter of the central telescopic rod of the pneumatic butterfly valve can reach more than 16 mm is a basic indicator of strength. The pneumatic butterfly valve is mainly used to restrain the shock and impact from the road surface when the spring rebounds after shock absorption. When passing uneven roads, although the shock absorption spring can filter the vibration of the road, the spring itself will have reciprocating motion, and the pneumatic butterfly valve is used to restrain the spring jumping. If the pneumatic butterfly valve is too soft, the body will jump up and down. If the pneumatic butterfly valve is too hard, it will bring too much resistance. The barrier spring works normally?

What factors affect the quality of plastic coated pneumatic butterfly valve
First of all, if you want to know what factors affect the quality of plastic coated pneumatic butterfly valve, you need to understand its application range, mainly in the transportation pipe and the selection of vibration free parts.
This kind of hose, which is used in various fields, has strict requirements for quality. For example, it is an essential accessory in industries closely related to life such as petrochemical industry, steam gas, etc. The size of the plastic coated pneumatic butterfly valve has a diameter, and the length of the hose also affects it. In terms of pressure, we learned a pressure unit P when we were in junior high school, and the working pressure here is also expressed in P.
In addition, in terms of medium, it is mainly decided according to the corrosion resistance table, and the material of each part is also decided by this. The material of each part directly plays a decisive role in the quality of the hose, because the connection part of the plastic coated pneumatic butterfly valve is often determined by some relatively small parts. Its chemical properties directly affect the quality of the connection.
Finally, the state. The so-called state refers to the state when the metal pipe is used. The minimum bending radius shall be calculated by referring to the length of various motion states of the metal pipe. With the help of these data, we can choose the length of the pneumatic butterfly valve, and then we can stop the device correctly, which also directly affects its quality.
