Sealing door lock mechanism for pressure container

Abstract

The invention relates to a sealing gate lock mechanism for the pressure vessel of a sterilizer. Aiming at the deficiencies of the existing mechanical gate lock mechanism for the pressure vessel of the sterilizer that the matching adjustment between a cavity and a cover is difficult during the use and the pressurized door of the pressure vessel of the sterilizer can be artificially opened under a working state, the invention provides a sealing gate lock mechanism which is easy to carry out coupling adjustment between the cavity and the cover and the pressurized door of the sterilizer cannot beopened artificially at discretion under the working state. The invention includes a cavity body, a cavity and cover assembly, a mechanical gate lock mechanism, a gate lock tightness judging mechanismand an electric door lock mechanism, wherein, the cavity and cover assembly comprises an adjustable cavity and cover screw, a plurality of cavity and cover fixing adjustable screws, a plurality of compression springs, a cavity cover and a sealing element; the gate lock tightness judging mechanism comprises a mechanical door lock mechanism tightness judging signal switch, a connection terminal forthe tightness judging signal switch, a coupling head guiding retaining screw and a coupling head guiding retaining 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 in 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, the airtight door can be opened manually. The airtight door lock mechanism used for pressure vessels
