Where is the vibration of pneumatic soft seal wafer butterfly valve mainly applied? 3. Off line of butterfly valve
3.1 Before construction, it must be confirmed with the process personnel whether the medium in the pipeline and valve is completely replaced and whether it is empty. If the medium pressure is not replaced or reduced, the construction personnel have the right to refuse the construction operation. Operators participating in offline construction shall wear work clothes, work shoes, helmets, protective glasses, protective gloves and other labor protection articles in strict accordance with the specifications. The operation site shall strictly abide by the principle of "three no injuries": "do not hurt yourself, do not hurt others, and do not be hurt by others".
3.2. Before offline, you can know the fault information of the valve in a targeted way, so as to deal with the problem in a targeted way during offline maintenance and improve work efficiency.
3.3 Disassemble from top to bottom. That is, first remove the connecting pipeline, connecting circuit, locator, and other accessories. The air source connector and wire terminal shall be effectively wrapped with insulating tape.
、 When using the pneumatic butterfly valve, we must pay attention to the model problem. If we can choose the correct model, the most basic work can be completed. If we choose the wrong pneumatic butterfly valve, many problems may occur, such as uncontrollable, or can not be used with other accessories, and even continuous failures, and even increase the maintenance cost.
