Protect well during use and non use:
1. When it is not used for a long time, it should be washed and dried, filled with talcum powder inside and coated with talcum powder outside, and placed indoors in a dry, cool and ventilated place.
2. It shall be stretched out and placed flat, and shall not be stacked or piled with weights.
3. Store away from heat sources.
4. Do not contact with acid, alkali, grease and organic solvent.
The vertical displacement of the CFM electric butterfly valve is roughly proportional to the load. With the change of the internal pressure of the capsule, the vertical stiffness increases continuously. The elasticity curve under the same pressure shows an inverse · S "property, and the air elasticity shows an obvious nonlinear elasticity. When the working stroke of the electric butterfly valve is compressed to a large value, the electric butterfly valve contacts the upper and lower bases on the round table, The rigidity of the electric butterfly valve increases significantly. It is shown in the figure that the more close to · 0, the greater the rigidity of the air spring. Moreover, with the increase of the air pressure, the rigidity increases at the same displacement, and the rigidity of the air spring is smaller near the design height.
