What is the maintenance workflow of pneumatic valves?
Pneumatic valves are valves driven by compressed air. Pneumatic valve only specifications, categories and working pressure to meet the procurement requirements, can be used to control the flow of air, water, steam, all kinds of corrosive media, mud, oil, liquid metal and radioactive media. It is not perfect in the current market economy environment. Under the concept of unified design of pneumatic valves, different innovations have been carried out to form a unique enterprise standard and product personality. Therefore, in the accessories of the pneumatic valve procurement contract, it is necessary to put forward detailed technical requirements when purchasing the pneumatic valve.
Using the characteristics of compressed air to promote the movement of multiple groups of pneumatic pistons in the actuator, and transfer the force to the beam and the internal curve track, drive the hollow spindle to rotate, transport the compressed air disc to each cylinder, change the inlet and outlet position, change the rotation direction of the spindle, adjust the number of cylinder combinations, And drive the load (valve) according to the rotation torque required by the load (valve).
1. The purpose of use and maintenance is to extend the service life of the valve and ensure a reliable switch.
2. Stem thread, often rub with stem nut, apply a little yellow dry oil. Molybdenum disulfide or graphite powder for lubrication.
3. Valves that are not often opened and closed should also be turned regularly, and lubricant should be added to the stem threads to prevent bite.
4. For outdoor valves, a protective sleeve should be added to the stem to prevent rain. Snow. Dust and rust.
5. If the valve is mechanical to be moved, oil should be added to the gearbox in time.
6. Keep valve clean.
