Pneumatic flange butterfly valve Guanglianda set rated electric butterfly valve trips when operated together? Smooth grease shall be compatible with butterfly valve metal materials, rubber parts, plastic parts and working media. When the working medium of pneumatic butterfly valve is gas, smooth grease can be used. Apply a thin layer of smooth grease on the surface of the seal device groove, apply a thin layer of smooth grease on the rubber seal, and apply a thin layer of smooth grease on the sealing surface and friction surface of the valve stem. After cleaning, the device should be started after the cleaning agent for the washed wall surface evaporates (can be wiped with a silk cloth not soaked in the cleaning agent), but it should not be placed for a long time, otherwise it will rust and be polluted by dust.
、 In addition, this can also increase the air pressure inside the butterfly valve to ensure a completely closed state inside. It is completely different from the elastic butterfly valve, and the upper and lower parts of the butterfly valve are equipped with bearings, so that a torsional operation can be carried out. Most of them are installed in large diameter pneumatic butterfly valves, In order to reduce the friction between the butterfly valve and the equipment during operation and cause certain density impact, a lubricant component will be added here, thus forming a protective layer for the butterfly valve.
