Electric sealing lock

Abstract

The invention relates to an electric sealing lock. The electric sealing lock is provided for overcoming the defects that the adjusting difficulty of cavity cover sealing fit of an existing door lock mechanism is high and a sealing door can be artificially opened when a pressure container in a sterilizer is in an operating state. The electric sealing lock has the advantages that adjustment of cavity cover sealing fit is easy, and the sealing door cannot be artificially opened at will when the sterilizer operates. The electric sealing lock comprises a cavity, a cavity cover assembly, a mechanical door lock mechanism, a door lock locking judgment mechanism and an electric door lock mechanism, wherein the cavity cover assembly is composed of a cavity cover adjustable screw, a plurality of cavity cover fixing adjustable screws, a plurality of compression springs, a cavity cover and a sealing element; and the door lock locking judgment mechanism is composed of a mechanical door lock mechanism locking judgment signal switch, a locking judgment signal switch connector, a connector guiding and fixing screw and a connector guiding and fixing nut.

Description

technical field [0001] The invention relates to a sealed door lock mechanism for a pressure vessel, in particular to a sealed door lock mechanism for a pressure vessel in a sterilizer. Background technique [0002] Existing sealed door lock mechanisms for pressure vessels in sterilizers are divided into mechanical door lock mechanisms and electric control door lock mechanisms. Among them, although the mechanical door lock mechanism can realize the automatic locking state when the pressure vessel in the sterilizer is under high pressure, it has the possibility of sealing when the pressure vessel in the sterilizer is under vacuum and slightly high pressure. The disadvantage that the door can be opened artificially, when the pressure vessel in the sterilizer is in a state of vacuum and slightly high pressure, it is very dangerous to artificially open the airtight door, because the airtight door on the pressure vessel is opened at this time , there will be high-pressure steam a...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims at the existing mechanical door lock mechanism used for the pressure vessel in the sterilizer. It is difficult to adjust the seal between the cavity cover and the cavity in use; when the pressure vessel in the sterilizer is in vacuum and The airtight door can be artificially opened under a slightly high pressure state, and the operator is easily scalded; and the existing electric control door lock mechanism for the pressure vessel in the sterilizer exists in use. In the event of a power failure, the airtight door on the pressure vessel cannot be opened, and it is easy to provide a sealing fit between the chamber cover and the chamber body; when the sterilizer is working, the operating procedure must be terminated first. The airtight door can only be opened, otherwise the airtight door cannot be opened; when the sterilizer encounters a power failure during work, an electric airtight lock can be used to open the airtight door manually
