The pressure release valves is also known as the ash warehouse release valve or the ash warehouse vacuum release valve. It is arranged on the top of the ash storage silo to protect the ash storage silo from excessive positive and negative pressure when the ash silo is overpressured and exhausted and abnormal temperature changes. The pressure and vacuum relief valve is installed on the top of the ash warehouse. When the back pressure of the ash silo is too high or the negative pressure is too high, it can act in time to adjust the working pressure of the dry ash silo within the normal range, so that the ash silo does not bear excessive positive or negative pressure, so as to ensure the safety of the ash silo. The valve is characterized by reliable action, tight sealing and long service life. It is an indispensable and important equipment in the ash storage system.
The performance of the pressure relief valve
The pressure relief valve is arranged in closed silos such as ash storage warehouses, limestone powder silos, and granaries. When the pressure and temperature in the silos are abnormal, the pressure and temperature in the silos are automatically adjusted to protect the silos from excessive or low pressure. .
The pressure relief valve is a pressure protection device for the transformer. When a fault occurs inside the transformer, the oil decomposes and produces a large amount of gas. Since the transformer is basically airtight, the connecting pipe connecting the oil pillow is relatively thin, and the small connecting pipe alone cannot effectively reduce the pressure quickly, resulting in a sharp increase in the pressure in the oil tank, which will cause Cause the transformer tank to rupture. The pressure relief valve will be opened in time to remove part of the transformer oil and reduce the pressure in the mailbox. After the pressure in the oil tank is reduced, the pressure relief valve will automatically close and keep the oil tank sealed.
