The technical scheme is as follows: the utility model provides a biological safety airtight door, its includes the door frame of being connected with the wall body, passes through the door body of hinged joint with the door frame, sets up fluted in the middle of the week portion of the door body, install the gasbag in the recess, the gasbag loops through electronic relief valve, one-way check valve, ooff valve and is connected its characterized in that with the air supply: one side that the door frame is located the laboratory or is located the laboratory outside is connected with the connecting block, the connecting block extends to the side of the door body, the connecting block with be connected with sealed the pad between the door body, when the airtight door is closed, sealed pad laminating the door body is located install first panel and second panel on the door frame of laboratory inside and the door frame that is located the laboratory outside respectively, first panel with install manual relief valve on the second panel respectively, manual relief valve respectively through the trachea with the gasbag is connected.
It is further characterized in that:
the connecting blocks are positioned on the upper part, the lower part, the left part and the right part of the door frame at the same time, and the positions, used for connecting the sealing gaskets, on the connecting blocks are sunken towards the direction far away from the door body;
a pressure regulating valve and a one-way electromagnetic valve are sequentially connected between the switch valve and the one-way check valve; a pressure sensor is connected between the one-way check valve and the electric pressure release valve;
the door body is provided with a limiting handle, an electromagnetic lock is arranged at the position of the limiting handle corresponding to the door frame, and an alarm is also arranged on the door frame;
and the first panel and the second panel are respectively provided with an emergency stop button and a door opening button.
After having adopted such structure, through the sealed pad of round of addding in door body department, when airtight door closed like this, except can rely on the gasbag between the door body and the door frame to guarantee the leakproofness, can also rely on sealed pad to guarantee the leakproofness to a certain extent, and even gasbag trouble leads to leaking sealed pad also can help to carry out the shutoff, thereby the security has been improved, reduce the virus, the possibility of bacterium leakage, guarantee biological safety, simultaneously if the valve trouble of control gasbag makes the unable pressure release of gasbag, thereby it also can come manual pressure release to open through being located indoor and outdoor manual relief valve to lead to the door body and open airtight door.
