Door sealing system of high-temperature sterilization cabinet

Abstract

The invention discloses a door sealing system of a high-temperature sterilization cabinet. The door sealing system comprises a communicating pipeline, an air compression device, a check valve, an air-control check valve and a door sealing safety four-way valve, wherein the gas output end of the air compression device communicates with one end of the air-control check valve by virtue of a pipeline, and the gas output end of the air compression device simultaneously communicates a first port of the door sealing safety valve by virtue of a pipeline; a second port of the door sealing safety valve communicates with gas in the high-temperature sterilization cabinet; the other end of the air-control check valve is connected to one air inlet of the communicating pipeline, and the other air inlet of the communicating pipeline is connected to one end of the check valve; the other end of the check valve communicates with a third port of the door sealing safety four-way valve, and a fourth port of the door sealing safety four-way valve communicates with the gas in the high-temperature sterilization cabinet; and two air outlets of the communicating pipeline communicate with two grooves which are formed in a door plate of the sterilization cabinet and are used for accommodating seal rings. Pressure compensation can be conducted in the case that the pressure of compressed air is insufficient by virtue of the gas in the cabinet, so that various potential safety hazards caused by insufficient sealing are eliminated.

Description

[0001] technical field [0002] The invention belongs to the technical field of sterilizing cabinet sealing, in particular to a door sealing system of a high-temperature sterilizing cabinet. Background technique [0003] The high temperature sterilization cabinet is a cabinet that uses steam for sterilization, and it is widely used in the pharmaceutical field. Under normal working conditions, the high temperature sterilization cabinet needs to seal the door of the sterilization cabinet and the inner space of the cabinet. Therefore, the prior art provides a door sealing system of the high temperature sterilization cabinet. [0004] Generally, the door panel of the high-temperature sterilization cabinet is provided with two grooves near the top and bottom of the door panel respectively, and a sealing ring is respectively accommodated in the two grooves, such as figure 1 As shown, the door sealing system of the high-temperature sterilization cabinet provided by the prior art i...
