Control system and control method for intelligent interlock safe pressure vessel

Abstract

The invention relates to a control system and a control method for an intelligent interlock safe pressure vessel, adopting human-machine interface conversation and set the interlock and the link-unlock of the pressure vessel. The control system comprises a pressure vessel and an electric cabinet; a pressure sensor and a temperature sensor are arranged at the upper end of the pressure vessel; signal output ends of the pressure sensor and the temperature sensor of the control system are connected with a signal input end of the electric cabinet; the opening and closing between an end cover in the pressure vessel and a pressure vessel body is controlled by a pneumatic mechanism, and the pressure vessel body is provided with a proximity switch matched with the pneumatic mechanism; a signal output end of the proximity switch is connected with the signal input end of the electric cabinet; a signal input end of the pneumatic mechanism is connected with a signal output end of the electric cabinet; a safe interlock execution mechanism is arranged between the end cover and the pressure vessel body, and the pressure vessel body is provided with a proximity switch matched with the safe interlock execution mechanism; and the signal output end of the proximity switch is connected with the signal input end of the electric cabinet. The control system and the control method have the advantages that the purpose of one-key operation, real-time safe monitoring, automatic recording, and safe opening and closing can be achieved.

Description

Technical field [0001] The invention relates to an intelligent interlocking safety pressure vessel control system and a control method for setting pressure vessel interlocking and interlocking by adopting a man-machine interface dialogue mode, and belongs to the field of pressure vessel manufacturing. Background technique [0002] CN2245593Y, the name "locking device for sealed container pressure vessel", it is composed of a base plate, a sliding plate, and a pressing plate to form a square or rectangular frame structure. The base plate is fixed on the container door frame. There is a sliding plate between it and the pressing plate. The sliding plate is completed by the lifting mechanism at the bottom. For clamping or unclamping action, the sliding plate has rectangular teeth, and its inclined surface presses the rectangular teeth of the container door, so that the container door presses the sealing rubber ring to realize the sealing purpose. Its shortcomings: First, the user can...

AI Technical Summary

Problems solved by technology

Its shortcomings: first, the user cannot realize the man-machine interface dialogue, and cannot intuitively realize the setting of pressure and temperature; second, the opening of the pressure vessel is manually controlled, which is not only poor in safety and reliability, but also prone to personal injury
