Abstract
The utility model discloses a warning indicator of a natural gas switch, which comprises a sensing system arranged on a natural gas switch, a power supply system, and an indication system which is connected with the power supply system and the sensing system respectively, wherein the sensing system comprises a magnet arranged on the natural gas switch and a reed switch located on a natural gas pipeline below the natural gas switch. The warning indicator disclosed by the utility model is characterized by simple structure and good use convenience and is directly mounted on the position of the natural gas switch; when the natural gas switch is under an opening state or a closing state, the current state of the natural gas switch is prompted through the indication system intuitively and remarkably; in addition, warning can be given before an accident happens; so good safeguard property is achieved.
Description
Technical field
The utility model relates to the natural gas in home field, specifically is a kind of rock gas open-close warning device.
Background technology
At present, along with improving constantly of living standards of the people, rock gas acts as a fuel and progresses into huge numbers of families.Yet in using the process of rock gas, people usually forget after use and close rock gas; And then gently then causing combustion gas to be poisoned, heavy then occurrence of large-area is exploded, " the natural gas leaking warning device " of present use on the market; It is the signal that after rock gas has taken place to leak and reached finite concentration, just given the alarm; And device need be installed in 1.5 meters scopes of source of the gas radius, belongs to monitoring afterwards, and safety is poor.
The utility model content
The technical matters that the utility model will solve provides a kind of rock gas open-close warning device, solves existing rock gas open-close warning device and reports to the police the problem of safety difference afterwards.
The technical scheme of the utility model is:
Rock gas open-close warning device comprises the induction system, the power-supply system that are arranged on the rock gas switch, is connected indication mechanism with power-supply system respectively with induction system; Described induction system includes the tongue tube that is arranged on magnet on the rock gas switch and the natural gas line that is positioned at rock gas switch below; Described indication mechanism comprises the conducting indication mechanism that is connected in series respectively with power-supply system and closes indication mechanism; The conducting indication mechanism comprises the conducting pilot lamp and first triode that is connected in series each other, and that closes that indication mechanism comprises that mutual polyphone connects closes the pilot lamp and second triode; And two incoming ends of described first triode and two incoming ends of second triode are connected respectively at two incoming ends of tongue tube.
Be in series with first resistance on the described conducting pilot lamp, described closing is in series with second resistance on the pilot lamp, be parallel with the 3rd resistance on the described indication mechanism, is connected with the 4th resistance between described first triode and second triode.
The advantage of the utility model:
The utility model is simple in structure, and is easy to use, directly is installed on the rock gas position of the switch, under switch opens or closed condition, all points out through indication mechanism, intuitively eye-catching, and can before accident generation prerequisite, warn, and safety is good.
Description of drawings
Fig. 1 is the structural representation of the utility model under rock gas switch opens state.
Fig. 2 is the circuit theory diagrams of the utility model.
Embodiment
See Fig. 1, Fig. 2, rock gas open-close warning device comprises the induction system, the power-supply system 5 that are arranged on the rock gas switch 1, is connected indication mechanism with power-supply system respectively with induction system; Induction system includes the tongue tube 4 that is arranged on magnet on the rock gas switch 13 and the natural gas line 2 that is positioned at rock gas switch 1 below; Indication mechanism comprises the conducting indication mechanism that is connected in series respectively with power-supply system 5 and closes indication mechanism; The conducting indication mechanism comprises first resistance 10, conducting pilot lamp 8 and first triode 6 that is connected in series successively, second resistance 11 of closing that indication mechanism comprises that polyphone successively connects, closes the pilot lamp 9 and second triode 7; And two incoming ends of first triode 6 and two incoming ends of second triode 7 are connected respectively at two incoming ends of tongue tube 4, are parallel with on the indication mechanism between the 3rd resistance 12, the first triodes 6 and second triode 7 and are connected with the 4th resistance 13.
The use principle of the utility model:
When natural air cock 1 was opened, tongue tube 4 was not worked, 6 conductings of first triode, and 8 conductings of conducting pilot lamp are lighted; Close when natural air cock 1, the magnet 3 that is arranged on the rock gas switch 1 drives tongue tube 4 work that are arranged on the natural gas line 2, and 7 conductings of second triode are closed pilot lamp 9 conductings and lighted.
