Description
Technical field
Acousto-optic pressure prior-warning device of the present invention belongs to the warning device technical field, is specifically related to a kind of device that adopts voice signal and wigwag to realize the pressure early warning.
Background technology
Pressure vessel is meant splendid attire gas or liquid, carries the Sealing Arrangement of certain pressure, and storage, reaction vessel, heat exchange container and separation container all belong to pressure vessel.
Pressure vessel is owing to reasons such as sealing, pressure-bearing and media; Blast, burn on fire easily and jeopardize the safety of personnel, equipment and property and the accident of contaminated environment, so pressure vessel generally is furnished with the internals that safety feature, table are taken into account complete various processes effect; At present, as important prison inspection product is all classified it in countries in the world.
Summary of the invention
Acousto-optic pressure prior-warning device of the present invention, technical matters to be solved is: a kind of pressure prior-warning device that adopts voice signal and wigwag to report to the police simultaneously is provided.
For solving the problems of the technologies described above, the technical scheme that the present invention adopted is: acousto-optic pressure prior-warning device comprises pressure transducer YL1, stop button AT1, pilot lamp HD1, hummer DL1, time relay sj 1 and intermediate relay ZJ 1.
Pressure transducer YL1, its normally opened contact YL1-1;
The coil SJ1-1 of time relay sj 1, its time-delay normally opened contact SJ1-2;
The coil ZJ1-1 of intermediate relay ZJ 1, its normally opened contact ZJ1-2.
The end of fuse RD1 links to each other with power end is anodal; The other end of fuse RD1 links to each other with the end of fuse RD2 after being connected in series the coil ZJ1-1 of normally opened contact YL1-1 and intermediate relay ZJ 1 of stop button AT1, pressure transducer YL1 successively, and the other end of fuse RD2 links to each other with the power end negative pole.
The normally opened contact ZJ1-2 of intermediate relay ZJ 1 is attempted by the two ends of the normally opened contact YL1-1 of pressure transducer YL1; The coil SJ1-1 of time relay sj 1 is attempted by the two ends of the coil ZJ1-1 of intermediate relay ZJ 1; The end of incoming cables of the time-delay normally opened contact SJ1-2 of time relay sj 1 links to each other with the end of incoming cables of the coil ZJ1-1 of intermediate relay ZJ 1; Link to each other with the leading-out terminal of the coil ZJ1-1 of intermediate relay ZJ 1 behind the leading-out terminal of the time-delay normally opened contact SJ1-2 of the time relay sj 1 serial connection pilot lamp HD1, hummer DL1 is attempted by the two ends of pilot lamp HD1.
The beneficial effect that the present invention compared with prior art has is: the present invention is at pressure vessel outer setting acousto-optic pressure prior-warning device; Pressure transducer in the device is used to gather the force value of pressure vessel, and when the force value of pressure vessel reached setting value, the normally opened contact of pressure transducer was closed; Alarm lamp in the device is bright; Hummer sends chimes of doom, and pilot lamp signal and buzzer signal can continue always, finds the unusual condition of device up to the staff; When pressing the stop button of lower device, reporting to the police just stops; The present invention adopts lasting sound and the dual alerting signal of light to carry out fault pre-alarming, effectively reminds the staff in time to take solution, has guaranteed equipment and personnel's safety; Also be provided with the time relay in the device,, effectively reduced the situation of device false alarm through the of short duration time-delay of the time relay.
Description of drawings
Do further detailed explanation below in conjunction with the accompanying drawing specific embodiments of the invention:
Fig. 1 is an electrical block diagram of the present invention.
