Torque of Yantai electric soft seal wafer butterfly valve? 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
、 3、 When it comes to the selection of electric control valve, it is necessary to decide whether to purchase electric control valve controller additionally. However, due to the general state, the controller needs to be purchased separately. In most states, a single controller will be used, so you need to purchase a controller. If the electrical control performance cannot meet the requirements of engineering design, it needs to be proposed for modification or re design. Of course, the electric control valve should not only pay attention to the pipeline parameters, but also pay attention to the environmental conditions of obligations, because the electric device of this type of control valve is electromechanical equipment, and the obligation state will be greatly affected by the environment of obligations.
