High pressure chamber door seal with leak detection system |
摘要 |
A high pressure chamber opening is equipped with a cylindrical element that features a circumferential flange. The circumferential flange features concentrically positioned primary and secondary O-ring seals that surround the chamber opening. A door is clamped to the circumferential flange and over the opening and the circumferential seals. As a result, the opening is sealed and an annular passage is formed between the seals. A port is formed in the cylindrical element so that the annular passage may communicate with a pressure switch. The port also communicates with a relief valve. The pressure switch signals the system operator when the pressure in the annular passage rises due to failure of the primary O-ring. The relief valve vents the annular passage when the pressure therein increases to a level where damage to the secondary O-ring could occur. The relief valve setting is such that the pressure within the annular passage may rise to a level where dry ice formation is prevented.
