QUICK-CLOSING DOOR FOR PRESSURE VESSELS

摘要

Sealing system of the widely-used quick-closing doors for pressure vessels is not guaranteed where the materials or products are treated with variable inner pressure from underpresure to overpressure and vice-versa. A risk is seen at ambient pressure in the vessel as to the pressure difference from underpressure to overpressure and with burnable atmosphere. This invention relates to a sealing system for quick-closing doors for pressure vessels which ensures safe operation with an atmosphere of burnable gases.
