Pneumatic valves are valves driven by compressed air. When purchasing pneumatic valves, it is only necessary to specify the specifications, types, and working pressures to meet the purchasing requirements. flow. It is not perfect in the current market economy environment. Zhejiang Shuangzhong Automatic Control Valve has carried out different innovations under the concept of unified design of pneumatic valves in order to make the products perform better, forming a unique enterprise standard and product personality. Therefore, it is very necessary to put forward technical requirements in detail when purchasing pneumatic valves, and reach a consensus with Zhejiang Shuangzhong Automatic Control Valve as an accessory of the pneumatic valve purchasing contract. The compressed air is used to push the movement of multiple sets of combined pneumatic pistons in the actuator, and the force is transmitted to the characteristics of the beam and the inner curved track, which drives the hollow spindle to rotate. Direction, according to the requirements of the rotation torque required by the load (valve), the number of cylinder combinations can be adjusted to drive the load (valve) to work.
1. The purpose of use and maintenance is to prolong the life of the valve and ensure reliable opening and closing.
2. The valve stem thread is often rubbed with the valve stem nut, and a little yellow dry oil, molybdenum disulfide or graphite powder should be applied to lubricate.
3. For valves that are not frequently opened and closed, turn the handwheel regularly, and add lubricant to the valve stem thread to prevent it from being bitten.
4. For outdoor valves, a protective cover should be added to the valve stem to prevent rain, snow, dust and rust.
5. If the valve is mechanically ready to act, add lubricating oil to the gearbox on time.
6. Always keep the valve clean.
