Abstract
The utility model discloses a domestic gas leakage alarm controller. An electromagnetic valve is installed on a gas pipeline. When the concentration of indoor leaking gas achieves certain extent, a control system controls the electromagnetic valve to close a gas conveying pipeline to avoid gas continuously leak to damage personal life safety. When the utility model is used, the electromagnetic valve can be only manually reopened by a manual resetting device, and the gas conveying pipeline is switched on. The utility model has the advantages of simple structure, sensitive operation and reliable use.
Description
The utility model relates to alarm, relates in particular to the warning and the controller that are used for the combustion gas of family expenses kitchen range.
Coal gas, gas leak, owing to cannot see, so usually spawn disastrous effect.At present,, unite use with vent fan or smoke exhaust ventilator though produced this type of alarm on the market, and the also following situation of Chang Yin and cause serious consequence in use: 1, the gas leakage amount is big, and vent fan is not enough to harmful gas is all drained; Though 2 report to the police, when attention has focused on something, as see TV, chitchat, play etc., off one's guard to reporting to the police; Though 3 report to the police, and have only old man or children in the family, unablely take capable measure.Therefore say the problem that alarm does not have thoroughly to solve the kitchen range gas leakage technically of stating.
The purpose of this utility model provides a kind of household gas leakage alarm controller, and when gas leakage reached finite concentration, the utility model can cut off source of the gas immediately, if want to recover ventilation, must can recover manually.
The purpose of this utility model is achieved in that
The utility model by: electronic type probe, early warning system, executive system, solenoid valve and manual reseting device etc. are formed; One solenoid valve is installed on admission line, the lead of control electromagnetic valve is connected in the circuit of executive system, solenoid valve is in open mode under the normal condition, draft tube is unimpeded, when gas leakage reached finite concentration, the electronic type probe was delivered to early warning system with perceptual signal, arrives executive system again, move on the valve plug in the executive system control electromagnetic valve, inlet channel is closed; If open breather line again, then need manual type to pass through manual reseting device, give solenoid valve an inverse current, make valve plug reset again, be communicated with breather line.
Described in detail below in conjunction with accompanying drawing:
Fig. 1 is a principle schematic of the present utility model;
Fig. 2 is a circuit diagram of the present utility model.
As shown in the figure: the solenoid valve 7 in the utility model is installed between source of the gas 3 and the kitchen range 5, and the harmful gas that electronic type probe 1 leaks out kitchen range 5 transfers electric signal to and is transferred to early warning system 2, when kitchen range gas leakage concentration reaches warning concentration, and relay J
1Work, at this moment: 1, sound and light alarm; 2, J
1-1Connect; When gas leakage concentration reaches must cut off source of the gas the time, early warning system 2 is sent the signal that turn-offs source of the gas, relay J to executive system 4
2Promptly start working, at this moment: J
2-1, J
2-2Connect, solenoid valve 7 energising work, with the adhesive that makes progress of the valve plug in the valve body, source of the gas then is cut off.Because of the solenoid valve top is provided with a permanent magnet, so work as relay J
2Discharge J
2-1, J
2-2During disconnection, though solenoid valve 7 outages, valve plug can not opened source of the gas by the permanent magnet adhesive.
When needs are connected source of the gas, start manual reseting device 6, promptly by manual button 8 engage relay J
3Circuit, at this moment: J
3-1, J
3-2Connect the voltage and the J at the magnetic head coil two ends of solenoid valve
2-1, J
2-2Polarity of voltage during conducting is just in time opposite, so electromagnet polarity is opposite, causes valve plug to move in the other direction, connects source of the gas.When button 8 disconnects J
3Discharge J
3-1, J
3-2Disconnect, solenoid valve does not have electricity, but solenoid valve base has a spring may command valve plug can not move upward, and then can keep source of the gas to connect.
What with coal gas be in example, the especially water gas there to be CO content surpasses 30%.CO is a kind of toxic gas of colorless and odorless, and it can make the people poison rapidly unconsciously and cause death.When kitchen range leaked for some reason, CO concentration reached at 0.025% o'clock in the kitchen, and the utility model is reported to the police immediately, and when CO concentration reached 0.15%, the utility model water promptly cut off the kitchen range source of the gas.
The utility model meets the relevant technologies regulation of the Ministry of Construction:
1, warning volume: 〉=70dB
2, the concentration of Bao Jinging:
Rock gas: 0.1%～1%
Liquefied petroleum gas (LPG): 0.1%～0.5%
CO content is less than 10% manufactured gas, manufactured fuel gas: 0.04%～0.5%
CO content is less than 20% manufactured gas, manufactured fuel gas: 0.04%～0.25%
CO content is less than 30% manufactured gas, manufactured fuel gas: 0.025%～0.15%
Adopt above-mentioned measure, controlled gas effectively and leaked the harm that brings to the mankind, and the utility model is easy to operate, effect is obvious.
