Abstract
The present utility model discloses a safety interlocking device for fast-open pressure vessels. The safety interlocking device which is capable of improving automation degree and safety performance comprises a door lock mechanism and an electromagnetic valve, a controllable programming device and a temperature sensor, a pressure transmitter, a spacing travel switch and an electric contact pressure gauge that are connected with the input end of the controllable programming device, and the output end of the controllable programming device is connected with the door lock mechanism and the electromagnetic valve. The safety interlocking device for fast-open pressure vessels has a higher automation degree and totally satisfies all the requirements of safety interlocking devices for fast-open pressure vessels in a document of [1999] No.154, namely, the document of <pressure vessel safety technique monitoring specification> that is issued by the State Bureau of Quality Technical Supervision (CSBTS).
Description
Technical field
The utility model relates to pressurized container, refers more particularly to the safety interlock of pressurized container.
Background technique
At present, along with emerging of for a long time new round medical reform scheme fermented by country, direction, target, basic principle and the major measure of China's medical and health system reform that this scheme is clear and definite further impels sterilization device to become hospital, pharmacy, the indispensable facility of biology laboratory.The explosive accident of sterilization pressurized container occurred repeatedly, and in rising trend but in recent years.For this reason, it is " safe technology of pressure vessel supervision rules " that National Quality ﹠ Technology Inspection Bureau has printed and distributed [1999] No. 154 files, and the 49th quick operating valve to fast opening type pressure container (lid) wherein clearly proposes to answer the design safety interlock.At present, the safety interlock of the fast opening type pressure container that China also designs, makes, finalizes the design by seeking unity of standard, have only part container production producer to be the pure machinery of the own supporting exploitation of pressurized container of producing or the safety interlock of semi-automation, this safety interlock operates cumbersome.
The model utility content
Technical problem to be solved in the utility model is: a kind of safety interlock that improves the door-opening pressure vessel of automaticity and Safety performance is provided.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the safety interlock of door-opening pressure vessel, comprise: door lock mechanism, solenoid valve, may command programmable device and the temperature transducer, pressure transmitter, limitation travel switch, the pressure gauge with electric contact that link to each other with the input end of may command programmable device, the output terminal of programmable logic controller (PLC) links to each other with door lock mechanism and solenoid valve.
Described door lock mechanism mainly is made up of A.C. contactor, door electric reducer.
The beneficial effects of the utility model are: automaticity of the present utility model is higher, the may command programmable device is according to the status parameter of the container door (lid) of limit sensors and pressure gauge with electric contact output, drive the tight mechanism of solenoid valve and door lock after treatment, it is locked safely that pressurized container is linked accordingly, play the effect of safety interlock, and can superpressure report to the police, very easy to use; Compare with manually original or pass automatic safety device, improved its Safety performance greatly, satisfied National Quality ﹠ Technology Inspection Bureau fully and send out i.e. the 49th the every requirement in " safe technology of pressure vessel supervision rules " of [1999] No. 154 files safety interlock device of fast opening type pressure container.
Description of drawings
Fig. 1 is a theory structure schematic representation of the present utility model.
Among the figure: 1, temperature transducer, 2, pressure transmitter, 3, limitation travel switch, 4, pressure gauge with electric contact, 5, programmable logic controller (PLC), 6, graphic control panel, 7, A.C. contactor, 8, the door electric reducer, 9, solenoid valve.
Embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.
As shown in Figure 1, the safety interlock of door-opening pressure vessel described in the utility model, comprise: door lock mechanism, solenoid valve 9, programmable logic controller (PLC) 5 and the temperature transducer 1 that links to each other with the input end of programmable logic controller (PLC) 5, pressure transmitter 2, limitation travel switch 3, pressure gauge with electric contact 4, the output terminal of programmable logic controller (PLC) 5 links to each other with door lock mechanism and solenoid valve 9, and described door lock mechanism mainly is made up of A.C. contactor 7, door electric reducer 8; In the present embodiment, described programmable logic controller (PLC) 5 also links to each other with graphic control panel 6.
Working procedure of the present utility model: correlation engineering parameter and status parameter that temperature transducer 1, pressure transmitter 2, limitation travel switch 3, pressure gauge with electric contact 4 will detect pressurized container inside send programmable logic controller (PLC) 5 to, after 5 pairs of data of programmable logic controller (PLC) are analyzed, are handled, the temperature and pressure data display that each point is measured in real time is on industrial touch screen 6, to make things convenient for the user to the pressurized container Stateful Inspection, and, when surpassing the pressure of setting, the corresponding alarm signal of industrial touch screen 6 outputs.
