Working principle of pneumatic butterfly valve
1. The pneumatic butterfly valve is a safety device, which can prevent the pressure equipment and vessels from breaking due to the pressure rise or the pressure inside the vessels exceeds the limit. Pneumatic butterfly valve is a safety device widely used in pressure vessels, boilers, pressure pipelines and other pressure systems to ensure the safe operation of the pressure system.
2. When the pressure of the container exceeds the design requirements, the pneumatic butterfly valve will automatically open to release the excessive pressure in the gas pressure reducer to prevent damage to the container or pipeline. When the pressure in the container drops to the normal working pressure, it will automatically close to avoid exhausting all the gas due to the overpressure in the container, which will lead to waste and production interruption.
3. Pneumatic butterfly valve is mainly composed of three parts: valve seat, valve disc (valve core) and loading mechanism. Some seats are integrated with the valve body, and some are assembled with the valve body and connected with the equipment. The valve disc is usually attached with a valve stem, which is fixed on the valve seat. Above the disc is a loading mechanism, which can adjust the loading size.
