Product Quality Inspection Before Leaving The Factory
1. Inspect the products produced on the electric actuator production line every day, 100% inspection. First, open the indicator cover and check whether the wiring is beautiful, whether the limit cams in the opening and closing directions are fully raised, and whether the pointer position is consistent with the actual position of the actuator. , whether the screws inside are tightened, check whether the back cover is correct, and check whether there is paint peeling on the appearance of the electric actuator. Dirt, manual wrench, waterproof connector, manual dust plug, sight glass, and sight glass gland are all installed. After everything is correct, use a laser marking machine to mark the product number on the back of the electric actuator. The product number should include the date of the day, and finally put the foam into storage.
2. Inspection of complete sets of valves: After the valve installation production line operator completes the debugging, he will take the production order to the quality inspector, and the quality inspector will check the production order and products one by one (inspection items: valve quantity, diameter, material, connection method. Whether the pressure is consistent with the production order, whether the voltage, control type, connection method of the electric actuator, whether it is an explosion-proof product, and whether it is consistent with the production order, whether the screws of the valve and electric actuator are tightened, whether there are any missing ones)
3. Inspection before packing: Check whether the product quantity, model, voltage, control method, and spare parts are consistent with the production order.
4. Inspection of random inspection products in the processing center: Once in the morning and afternoon every day, take the inspection item list to the processing center and randomly select a processed product from each machine. Find the processing center operator and ask him to measure one by one according to the inspection item list. , and keep records.

The Use Of Ball Valve
Since ball valves usually use rubber, nylon and polytetrafluoroethylene as seat sealing ring materials, their service temperature is limited by the seat sealing ring material. The cut-off function of the ball valve is accomplished by the metal balls pressing against each other between the plastic valve seats under the action of the medium (floating ball valve). Under the action of a certain contact pressure, the valve seat sealing ring will undergo elastic-plastic deformation in local areas. This deformation can compensate for the manufacturing accuracy and surface roughness of the ball and ensure the sealing performance of the ball valve. And because the seat sealing ring of a ball valve is usually made of plastic, when selecting the structure and performance of the ball valve, the fire resistance and fire prevention of the ball valve must be considered, especially in petroleum, chemical industry, metallurgy and other departments, in flammable and explosive media When ball valves are used in equipment and piping systems, more attention should be paid to fire resistance and fire prevention.
