Embodiment 1

[0010] Embodiment 1: with reference to attached figure 1 and 2 . An intelligent interlocking safety pressure vessel control system, which includes a pressure vessel 1 and an electric control box 19, the electric control box 19 is composed of a CPU main control board 21, a touch screen 18 and a pneumatic solenoid valve 20, and the two-way connection between the CPU main control board and the touch screen 18 Data exchange, one-way data exchange with the pneumatic solenoid valve 20. The manufacture of the pressure vessel 1 is a prior art, and will not be described here. The upper end of the pressure vessel 1 is provided with a pressure sensor 2, a temperature sensor 7 and 8, and the signal output terminals of the pressure sensor and the temperature sensor are connected to the signal input terminal of the electric control box 19; The opening and closing between the container bodies adopts a pneumatic mechanism 14 and a proximity switch 13 that cooperates with the pneumatic mech...

Embodiment 2

[0011] Embodiment 2: On the basis of Embodiment 1, the intelligent interlocking safety pressure vessel control method, the CPU main control board has a built-in man-machine interface dialogue software and pressure and temperature comparison software. The working pressure, working temperature, and working time of the pressure vessel are set, and segmental control is realized. When work is required, the CPU main control board closes the end cover 12 through the pneumatic electromagnetic command pneumatic mechanism 14. After the end cover 12 is closed in place, it is connected with the pneumatic The proximity switch 13 coordinated with the mechanism transmits the signal that the end cover 12 is closed in place to the CPU main control board, and the CPU main control board instructs the latch in the safety interlock actuator 9 to lock the end cover 12 with the pressure vessel body, and the proximity switch 11 locks the latch The signal in place is transmitted to the CPU main control...

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 control method for setting the interlocking and opening of pressure vessels by means of man-machine interface dialogue, belonging to the field of pressure vessel manufacturing. Background technique [0002] CN2245593Y, titled "door locking device for airtight container pressure vessel", it consists of a base plate, a slide plate, and a pressure plate to form a square or rectangular frame structure, the base plate is fixed on the container door frame, and the slide plate is between it and the pressure plate, and the slide plate is pushed by the lifting mechanism at the bottom to complete Clamping or loosening 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 achieve the purpose of sealing. Its shortcomings: first, the user ...
