Pneumatic butterfly valves have very important applications in many industries. Today, we know that braid is a curved capsule made of paste with metal wire. It is also called pneumatic butterfly valve in industry. Also called pneumatic tire, corrugated pneumatic tire, safety, leather tiger, etc. Pneumatic butterfly valve is a common product type in pneumatic butterfly valve industry. Today, Dongfeng's Xiaobian takes you to learn about pneumatic butterfly valves.
The two ends of the pneumatic butterfly valve capsule need to be connected with two plates to form a compressed air chamber. The cable itself does not provide the bearing capacity, but the compressed air is filled with capsules. Generally speaking, the number of crimp capsules is usually 1-3. If the requirements are different, 4 or more crimp capsules can be designed and manufactured, which can be superimposed by two pneumatic butterfly valves under certain conditions. There are five flange sealing forms at the end of pneumatic butterfly valve and connecting plate: LHF, JBF, GF, HF and ZF.
What are the three types of pneumatic butterfly valve connections?
1. Looper flange connection mode: the size of pneumatic butterfly valves at both ends is much smaller than the maximum outer diameter of the winding bag, so it is not necessary to use special flange rings and common end plates for fixed connection;
2. Self sealing type: self sealing without flange connection pressure enters the end plate filled with compressed air
3. Fixed flange connection type: the edge size at both ends of the pneumatic butterfly valve is equal to or slightly less than the maximum outer diameter of the crankshaft. After drilling several holes, use the blue ring to fasten the connection with the end plate.
