We usually use valve electric devices in many places, but we don't know much about valve electric devices. So what is the assembly process of the valve electric device? Let's learn together now.
1. Preparations before assembly
Before assembling valve parts, it is necessary to remove the burrs formed by machining and welding residues, clean and cut fillers and gaskets.
2.cleaning of valve parts
The valve installed as a fluid pipeline control must have a clean inner cavity. In particular, valves used in nuclear power, medicine, and food industries have stricter requirements on the cleanliness of the valve cavity in order to ensure the purity of the medium and avoid medium infection. The valve parts should be cleaned before assembly, and the cutting chips, residual smooth oil, coolant and burrs, welding slag and other dirt on the parts should be washed and cleaned. The valve is usually cleaned by spraying with alkaline water or hot water (kerosene can also be used for scrubbing) or cleaning in an ultrasonic cleaning machine. After the parts are ground and polished, Zui post-washing is required. Post-Zui cleaning is usually to clean the sealing surface with gasoline, then dry it with compressed air and wipe it with a cloth.
