Preparation of packing and gaskets for fully welded ball valves

Preparation of packing and gaskets for fully welded ball valves, understanding the cleaning and assembly of their parts, cleaning of fully welded ball valve parts: installing fluid pipelines to hold the valve, the inner cavity must be clean. Before assembly, the valve parts should be cleaned to remove chips, debris, residual lubricating oil, coolant, burrs, welding slag, or other dirt.
Packing and gasket preparation: Graphite packing is widely used due to its corrosion resistance, good sealing, and low friction coefficient. Packing and gaskets are used to prevent media leakage through the valve stem and valve cover and flange joints. These accessories must be prepared for cutting and use before valve assembly. Especially for nuclear power, medicine, and food industry valves, in order to ensure the purity of the medium and avoid medium contamination, the cleanliness of the valve cavity is strictly required,
Assembly of fully welded ball valves: Valves are usually assembled with the valve body as the reference part according to the order and method specified in the process. Before assembly, the parts should be inspected to prevent parts that have not been deburred and cleaned from entering the final assembly. During assembly, parts should be handled with care to avoid bumping or scratching the processed surface.
