5. Cleaning of the pneumatic amplifier Since the pollutants in the compressed air will lead to throttling blockage of the pneumatic amplifier, proper steel wire can be used for cleaning. During reassembly, it should be noted that the amplifier diaphragm needs to be subjected to uniform force to effectively prevent blockage or leakage.

What are the structural characteristics of the electric butterfly valve?
1. Under high temperature and high pressure conditions, it still has a stable sealing function. Its special sealing system can ensure that all temperature scales from ultra-low temperature to ultra-high temperature have a high sealing function
2. The 3D preferential sealing system and the optimized design make the opening resistance of the valve small. The sealing surface of the butterfly plate is a cone protruding upward. When opening, all points on the peripheral surface of the butterfly plate are closed together and separated from the sealing ring, and solids are not easy to accumulate on the sealing surface. The closing process of the valve is closed through the elastic pressure of the sealing ring
3. There is no phase jam between the electric butterfly plate and the seal ring. What are the structural characteristics of the electric butterfly valve? 　　
4. The sealing function of the valve is not affected by temperature changes
5. The valve rod shaft diameter seal adopts the graphite restricted shaped seal ring. In conclusion, zero leakage is ensured. The metal seal plus the front, middle and rear of the fire are zero leakage, so it is essentially fire safe
