Metal constant-pressure sealing door

The utility model relates to a metal constant pressure sealing door which comprises a clean room, a constant pressure assembly, a pressurization assembly and a decompression assembly, the inner wall of the clean room is provided with a door frame, and the outer side of the door frame is rotatably connected with a metal clean door. The metal cleaning door has the advantages that the pressurizing assembly is driven to enable air pressure to enter the interior of the cleaning room, when the air pressure is too large, the pressure reducing assembly is used for discharging the air pressure, and meanwhile the constant pressure assembly is matched to detect whether the pressure intensity inside and outside the metal cleaning door is balanced or not, so that the constant pressure state inside and outside the metal cleaning door is achieved; the practicability of the equipment is improved, and actual application and operation are facilitated. 本实用新型涉及金属恒压密封门，包括洁净室、恒压组件、增压组件和减压组件，洁净室的内壁开设有门框，门框的外侧转动连接有金属洁净门。本实用新型的有益效果在于
