Abstract
The invention discloses an alarm type gas leakage induction cutoff switch. The alarm type gas leakage induction cutoff switch comprises a power supply, a gas detector, a central processing system, an alarm device and an executing system, wherein the central processing system is respectively connected with the gas detector, the alarm device and the executing system, and the power supply is used for supplying power to all the parts. The central processing system comprises a central processor and a comparator, signals are emitted by the gas detector and transmitted to the central processor via the comparator, the central processor comprises a display module and an input module and can automatically input set values of the comparator, and the central processor can further emit commands to the alarm device and the executing system. The alarm type gas leakage induction cutoff switch provided by the invention simultaneously has the functions of detection, alarm and cutoff, further has a manual reset function, is simple and convenient to mount and can be used repeatedly.
Description
Technical field
The present invention relates to a kind of alarm type gas leakage induction and cut off switch.
Background technique
Raising along with development in science and technology and industrial level, various flammable or toxic gases are used in family daily life or industrial production in a large number, offer convenience when being worth to people, the events such as the various blasts that cause because of gas leakage, murder by poisoning emerge in an endless stream, and the various infringements that bring thus also usually allow the people startling.Therefore, have the equipment of the several functions such as gas leakage detection, warning, cut-out, become the focus of people's research.
Summary of the invention
The purpose of this invention is to provide the induction of a kind of alarm type gas leakage and cut off switch, the concentration of monitored gas in the Real-Time Monitoring environment is in case detectable concentration when setting concentration, is then reported to the police and cut off simultaneously the source of the gas passage.
Switch is cut off in described alarm type gas leakage induction, comprises power supply, gas detector, central processing system (CPS), alarm, executive system, and central processing system (CPS) links to each other with gas detector, alarm, executive system respectively, and power supply is powered to various piece.Described central processing system (CPS) comprises central processing unit (CPU) and comparator, and signal is sent by gas detector, is transferred to central processing unit (CPU) through comparator, comprises display modular and load module in the central processing unit (CPU), voluntarily the setting value of input comparator.Gas detector is with the concentration signal that detects, be transferred to comparator, comparator is after relatively, if signal value surpasses setting value, then send signal to central processing unit (CPU), send instruction by central processing unit (CPU) to alarm and executive system, alarm sends warning message, and executive system is carried out and cut off the source of the gas channel operation.
Described executive system comprises housing, and air delivering pipeline access port and exit are arranged on the housing, is fixed with motor-driven screw rod on the inner walls, and described screw rod links to each other with air valve, by the switch of screw rod extension and contraction control air valve.Under the normal state, air valve is in open mode, and when gas detector surpassed setting value with the concentration signal that detects, central processing unit (CPU) sent instruction to executive system, and the motor driving screw rod stretches or shrinks, and closes thereby drive air valve.Preferably, described outside also is provided with the hand switch of control motor, and is manually opened behind convenient in case of necessity manually-operable or the described alarm type gas leakage induction cut-out switch automatic closing air valve, makes the induction of alarm type gas leakage cut off switch and resets.
Described executive system is installed on the air delivering pipeline.The each several part that switch is cut off in the induction of the described alarm type gas leakage structure that can be integrated in one, or optionally arrange separately, connect via circuit.
Alarm type gas leakage provided by the invention induction is cut off switch and is had simultaneously detection, warning and cutting function, and has the hand reset function, installs simple and conveniently, can be repeatedly used.

Embodiment
Below in conjunction with embodiment the present invention is described further, but is not construed as limiting the invention.
As shown in Figure 1, switch is cut off in a kind of alarm type gas leakage induction, comprise power supply, gas detector, central processing system (CPS), alarm, executive system, described central processing system (CPS) comprises central processing unit (CPU) and comparator, and signal is sent by gas detector, is transferred to central processing unit (CPU) through comparator, comprise display modular and load module in the central processing unit (CPU), the setting value of input comparator voluntarily, central processing unit (CPU) sends instruction to alarm and executive system again, and power supply is powered to various piece.Gas detector is with the concentration signal that detects, be transferred to comparator, comparator is after relatively, if signal value surpasses setting value, then send signal to central processing unit (CPU), send instruction by central processing unit (CPU) to alarm and executive system, alarm sends warning message, and executive system is carried out and cut off the source of the gas channel operation.
Shown in Fig. 2,3, described executive system comprises housing 5, and pneumatic tube 1 access port and exit are arranged on the housing 5, be fixed with motor driving screw rod 3 on housing 5 inwalls, motor driving screw rod 3 upper ends are connected with iron plate 6, and iron plate 6 links to each other with air valve 2, are elastic sealing structure on the air valve 2 close faces of housing 5.Under the normal state, air valve 2 is in open mode, and when gas detector surpassed setting value with the concentration signal that detects, central processing unit (CPU) sent instruction to executive system, and motor driving screw rod 3 is stretched upwards, and closed thereby drive air valve 2.Described housing 5 outsides also are provided with the hand switch 4 of control motor, and are manually opened behind convenient in case of necessity manually-operable or the described alarm type gas leakage induction cut-out switch automatic closing air valve, make the induction of alarm type gas leakage cut off switch and reset.
The induction of the alarm type gas leakage of present embodiment is cut off switch and is had simultaneously detection, warning and cutting function, and has the hand reset function, installs simple and conveniently, can be repeatedly used.
