Pressure relief valve

Set the safety valve Pressure Relief Valve flap in the operating conditions began to rise the import of static pressure. At this pressure, a measurable opening height starts and the fluid is continuously discharged visually or audibly. Also known as opening pressure, setting pressure. 2, the maximum calibration burst pressure The same batch of rupture disc, burst test at a certain temperature, if the product is qualified, then the maximum burst pressure test for the batch of bursting disc maximum calibration burst pressure. 3, the maximum relief pressure relief valve flap valve state to achieve the provisions of the maximum import pressure after opening height. The maximum relief pressure of the rupture disc device is the maximum pressure in the relief state. 4, at one end of the valve can be separated from other systems of one or more devices (containers), using the corresponding pipe system connection, and the middle of the valve without the partition, can be regarded as a separate pressure system.
