Lined Valve, also known as fluoroplastic lined corrosion-resistant valve, is a valve made by molding polytetrafluoroethylene resin and then placing it on the surface of the inner wall of the steel or iron valve pressure-bearing part.
1. The following aspects should be considered when installing polytetrafluoroethylene lined valves:
1. Safety: the safety of personnel and equipment during installation.
2. Installation location: operators should have enough space for installation and ensure the convenience of disassembly and maintenance of valves and accessories.
3. Installers should understand that the regulating valve is a precision instrument and equipment and cannot be collided to avoid damage.
4. It should be installed vertically on the pipeline. If the dead weight is large or there is vibration, support should be added.
2. Before installing the polytetrafluoroethylene lined valve on the pipeline, it is necessary to clean the dirt and welding slag in the valve body connection and pipeline.
3. The flow direction of the medium is consistent with the direction of the arrow on the valve body.
4. The gasket connected to the pipeline cannot penetrate into the pipeline. Pay attention to the gasket material to be suitable for the process medium.
5. The valve flange bolts should be tightened evenly to avoid excessive pipeline pressure.
6. The actuator has been assembled before leaving the factory and does not need to be adjusted during installation.
7. Before installing the air supply pipeline, compressed air should be introduced to discharge the dirt in the pipe.
8. Before operating the valve, if the manual mechanism is in working state, the manual mechanism should be opened to the neutral state, otherwise it will block the movement of the valve.
