Abstract

The invention belongs to a sealed door, and in particular discloses a ram type sealed door, which consists of a door panel component, a door frame component, a lifting opening-closing mechanism and a positioning guide mechanism. The upper door frame and the door are removable and connected with right and left door frames by bolts. Through the lifting opening-closing mechanism and the positioning guide mechanism, the door can align and position automatically, so as to realize non-resistance opening and closing of the door panel; and a pushing force of a cylinder in the lifting opening-closing mechanism is completely converted into sealing pressure of the door panel so as to fully and effectively separate the space before and after the door.

Description

technical field [0001] The invention belongs to a hermetic door, in particular to a gate-type hermetic door. Background technique [0002] In workplaces that require strict isolation between internal and external passages, such as radioactive places and various special laboratories, etc., where passage sealing doors must be provided, if strict sealing cannot be achieved, cross-contamination may occur, which in turn leads to a series of environmental and health problems. question. [0003] There are two main types of airtight doors: [0004] 1). Inflatable airtight door, that is, after the door is closed, the air is added to the sealing strip to expand the sealing strip to achieve sealing. The disadvantage is that the equipment and structure are complicated, a supporting air source is required, and the life of the sealing strip is short. [0005] 2). The mechanical swing type airtight door, that is, the general side door, is provided with a spiral pressure applying mechani...
