Application of metal pneumatic butterfly valve in automobiles?
The metal pneumatic butterfly valve is mainly used in automobile shock absorption. How is the metal pneumatic butterfly valve used in automobile shock absorption?
? 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. During the modification of the suspension system, the hard pneumatic butterfly valve should be matched with the hard spring, and the hardness of the spring is closely related to the vehicle weight. Therefore, the heavier vehicles usually use the hard pneumatic butterfly valve. The device connected with the shock inducing crankshaft is used to counteract the modified vibration of the crankshaft.
Most pneumatic butterfly valves are installed inside the suspension system of automobiles. The pneumatic butterfly valve of automobile is also called "suspension", which is composed of spring and pneumatic butterfly valve. The pneumatic butterfly valve is not used to support the weight of the vehicle body, but to prevent the spring from bouncing after shock absorption and absorb the energy of road impact. The spring plays the role of easing the impact, changing the "large energy single impact" into "small energy multiple impact", while the pneumatic butterfly valve is gradually reducing the "small energy multiple impact".
The pneumatic butterfly valve is indispensable in the automobile device, unless you want to feel a pit, a bouncing pleasure.

What must be done for metal compensator to be qualified
Everything is good or bad, and the products we consume must pass strict inspection before leaving the factory. Only qualified products can leave the factory. So, what conditions should we have before we can leave the factory?
1. Materials of other structural parts must have material certificates.
2. The materials of compensator elements and barrel joints must be provided with material certificates, and they shall be re inspected as qualified according to relevant specifications.
3. The longitudinal welds of components must be 100% X-ray flaw detection, which is acceptable at Level I. The longitudinal welds of cylinder section must be 100% X-ray flaw detection, which is acceptable at Level II.
4. The circumferential weld between element and cylinder section must pass dye penetrant inspection and kerosene leakage inspection.
5. After the whole assembly of elements and cylinder sections is completed, the air tightness and strength tests must be stopped according to the specifications.
6. The surface (inside and outside) of the element shall be free of scratches or welding spatters larger than the negative deflection of the plate.
7. The overall dimensions shall meet the requirements of drawings and relevant specifications.
The above are some general specifications of metal compensators introduced by Xiao Bian, which can be created by ourselves.
