The advantage applies of the utility model household safe gas burning system is in following several respects:
(1) novel gas kitchen range
1, gas range (comprising natural gas range) adopts pulse firing, and blowout protection adopts the thermion sensing:
Gas range up-to-date on the market is established protector of accident extinguishing; blowout protection is by hot dipole sensing; shortcoming is that reaction is slow; because dipole heating or cooling need the regular hour; treat that hot dipole temperature rising late gate just opens so must push certain hour when starting shooting at every turn; when running into accident extinguishing, also need certain hour could cool off valve-off, can cause gas leak during this.
The point device of the gas range of the utility model household safe gas burning system adopts the pulse firing mode of known water heater, and thermion sensing, solenoid control are adopted in the accident extinguishing protection.Advantage is: gas range knob one is twisted and is promptly lighted a fire successfully; As run into and flame-out close immediately, not only convenient but also energy-saving safe.
2, the novel gas kitchen range adopts multiple leak-proof measure:
At present, average family gas range and water heater be not owing to itself possess safe drip-preventing function, and the keying of gas passage is mainly by gas tank (or piped gas) total valve, the control of firepower control valve.Shortcoming is that the open and close of total valve are very inconvenient; Do not possess leak protection and warning function, potential safety hazard is very big.
The utility model gas range and pipe-line system thereof have adopted multiple leak-proof measure:
(1) dual-coil electromagnetic valve structure: install a magnetic valve additional at piped gas or gas tank pressure-reducing valve back, another magnetic valve is installed on gas range the inside (the gas entry place of firepower control valve).Two magnetic valves are controlled by pulse igniter simultaneously.Turn the firepower control handle, pulse igniter is lighted a fire immediately, opens two electromagnetic valves simultaneously, and burning is kept in the coal gas circulation.When stubborn tempering power control handle or accident extinguishing, pulse igniter makes two magnetic valves discharge simultaneously immediately, closes pipeline and imports and exports.At this moment, because first magnetic valve is installed on the pressure-reducing valve place, the main entrance of coal gas is blocked, therefore, even pipeline gas leakage till just the coal gas between two magnetic valves having been leaked, can not caused danger yet.
(2) baroswitch control: (on the gas piping between two magnetic valves) installs a baroswitch in gas range, in order to the power supply of control impuls igniter.When seal for pipe joints and when coal gas is arranged, because the effect of coal gas air pressure, baroswitch is in logical state, and pulse igniter power connection, pulse igniter can be lighted a fire at any time.If do not have coal gas or gas leakage in the pipeline, baroswitch is in off-state, and ignition power is cut off, and igniter can't be lighted a fire this moment.
The acting in conjunction meeting of dual-coil electromagnetic valve and baroswitch makes effect very obvious.Particularly without gas range the time, the gas pipe two ends are all blocked by two electromagnetic valves, and therefore, as long as pipeline a little leaks gas, the very fast reduction of intraductal atmospheric pressure disconnects baroswitch, cuts off ignition power automatically to igniter can't be lighted a fire.Like this,, greatly reduce the possibility of gas poisoning, gas explosion, make the probability that leakage takes place almost nil just for gas piping is provided with dual fail-safe.
(3) leakage alarm: if pipeline gas leakage, baroswitch is connected buzzer warning.
(2) New-type water heater
In like manner, water heater also can be taked multiple leakproof: because water heater itself adopts pulse firing, the flame-out thermion sensing that adopts, and a magnetic valve has been installed at the gas entry place, therefore, only need the driving circuit for electromagnetic valve of igniter also movingly a little, make it to drive two magnetic valves, by the connection of gas range baroswitch and igniter, buzzer being joined then gets final product.
(3) during the public same gas piping of coal gas left and right sides kitchen range and water heater, the magnetic valve at shared pressure-reducing valve place only needs the output line of the drive circuit of gas range and water heater and connects (same polarity is joined) to arrive pressure-reducing valve place magnetic valve just passable.
The utility model household safe gas burning system is provided with multiple insurance at the safety problem of gas pipeline, has solved the problem that gas pipeline is caused danger because of leakage; Baroswitch is by the gaseous-pressure sensing, so buzzer warning is not subjected to the influence of environmental factor as humidity, oil smoke, dirt etc., dependable performance.
Devices such as the related magnetic valve of the utility model, baroswitch, pulse igniter, firepower control valve all are a little modified devices, its original technology is very ripe at present, therefore it is little to improve the difficulty of making, cost is also lower, and (the novel gas kitchen range only needs the cost of the about 20-30 of increase unit on the basis of original gas range, still less about 10 yuan of water heater), promote than being easier to.

The specific embodiment
Now specify in conjunction with the accompanying drawings:
(1) novel gas kitchen range
1, gas range is connected with gas tank and magnetic valve
As shown in Figure 1, different with normal conditions is to have installed a magnetic valve 3 additional in the pressure-reducing valve back, coal gas in the gas pipe 17 is subjected to the control of this magnetic valve 3, and magnetic valve 3 is controlled by pulse igniter 7 (see figure 3)s in the gas range 14, has control line 15 to be connected between magnetic valve and the gas range 14.(when rotating counterclockwise gas range 14 firepower control valve firepower control valve knobs 6) magnetic valve is opened (see figure 2) during use, uses back (clockwise rotate gas range knob 6 time) on earth magnetic valve and discharges and close.
As shown in Figure 2, from appearance, the utility model gas range 14 has assembled a SR 8, a thermion sensor 10 and a high-tension ignition pin 12 than ordinary gas stove more.Its effect and function have detailed description in the back.
2, gas range internal structure
As shown in Figure 3, the escape pipe of magnetic valve 5 bases of gas range itself is connected with the air inlet pipe of firepower control valve 6 ', baroswitch 4 is installed on the gas pipe near magnetic valve 5, two binding posts of buzzer 11 are connected with pulse igniter 7 with baroswitch 4 respectively, and two binding posts of other of baroswitch 4 and magnetic valve 5, SR 8, microswitch 9, thermion sensor 10, high-tension ignition pin 12 all are electrically connected with pulse igniter 7.Control line 15 is magnetic valve 3 connecting lines of pulse igniter 7 and close pressure-reducing valve 2.
3, gas range firepower control valve
The firepower control valve 6 ' of the gas range 14 of the utility model household safe gas burning system is compared different with the firepower control valve (containing mechanical igniter) of ordinary gas stove: the firepower control valve 6 ' of gas range 14 of the present utility model has installed microswitch 9 additional, and with having removed the mechanical ignition function, (with pulse igniter 7 igniting).Microswitch 9 is installed near the turning cylinder of firepower control valve 6 ', (with the contact position of microswitch 9) has a bossing 21 on the turning cylinder of firepower control valve 6 ', the Push And Release of microswitch 9 is by 6 ' the turning cylinder transmission of firepower control valve, when firepower control valve knob 6 is in original position (closed condition), bossing 21 backs down (disconnection) with microswitch 9, and microswitch 9 returns are connected after turning firepower control valve knob 6 counterclockwise.Control line 20 is the connecting line of microswitch 9 and pulse igniter 7.
4, the gas range and the pipe-line system course of work
As Fig. 5, shown in Figure 6, the magnetic valve 3 at pressure-reducing valve 2 places and gas range 14 magnetic valves 5 own can adopt the magnetic valve of common water heater on the market, are all pressed on pulse igniter 7; Magnetic valve 5 and pulse igniter 7, and buzzer 11, firepower control valve 6 ' be installed in the gas range 14; SR 8 is installed on gas range 14 control panels.(direction of arrow is the coal gas circulating direction among the figure).
When using this gas range 14 for the first time, because gas pipe does not have coal gas for 17 li, the air pressure in the pipeline is with the atmospheric pressure unanimity, and baroswitch 4 places position 2, buzzer 11 can pipe after loading onto battery, therefore, must click SR 8, force start is magnetic valve 3 once, make pipeline be full of coal gas, baroswitch 4 places position 1, and closes buzzer 11, thereby makes gas range 14 be in the igniting readiness.
Gas range 14 is not when using, because firepower control valve knob 6 returns, microswitch 9 disconnects, pulse igniter 7 dumps, and magnetic valve 3 and magnetic valve 5 are in closed condition simultaneously, at this moment, because magnetic valve 3 blocks the gas pipe inlet, therefore, even pipeline gas leakage, till just the coal gas of gas pipe between two magnetic valves 3,5 having been leaked, spillage risk can not take place yet.
When turning firepower control valve knob 6 counterclockwise, microswitch 9 is connected, pulse igniter 7 power connections and igniting, and magnetic valve 3 and magnetic valve 5 adhesives simultaneously, gas piping is unimpeded, and the igniting success is also kept burning.
Behind stubborn tempering force control valve knob 6, gas passage is closed, burn-out, and microswitch 9 disconnects simultaneously, and pulse igniter 7 power supplys are cut off, and magnetic valve 3 and magnetic valve 5 discharge.
Gas range 14 is in use as accident extinguishing, and thermion sensor 10 works very soon, by pulse igniter 7 magnetic valve 3 and magnetic valve 5 is closed, at this moment, even firepower control valve 6 ' return not because magnetic valve 3 has cut out, can not leak gas yet.But this moment is because microswitch 9 is still connected, so pulse igniter 7 power supplys do not disconnect yet, but can not light a fire.
In the combustion process, if gas pipe gas leakage is relatively more severe, perhaps gas pipe comes off, intraductal atmospheric pressure reduces, and makes baroswitch 4 place position 2, closes pulse igniter 7 power supplys, magnetic valve 3 and magnetic valve 5 discharge, and have closed the coal gas source, therefore security incident can not take place.
Gas range 14 is not when using, and two magnetic valves 3,5 are in closed condition simultaneously, and this moment is as long as pipeline a little leaks gas, the very fast reduction of gas pipe internal gas pressure makes baroswitch 4 place position 2, starts buzzer 11 and reports to the police, and break impulse igniter 7 power supplys, next use can't be lighted a fire.Only after gas piping is repaired, click SR 8 again, gas range can normally use again.
The pulse igniter 7 of gas range 14 of the present utility model is converted by the pulse igniter of common water heater, its electrical schematic diagram is seen accompanying drawing 6, it is on the drive circuit of original magnetic valve and has connect the one-level driving, such pulse igniter just can drive two magnetic valves simultaneously, the components and parts of the driver that increases are R27, R28, Q10, Q11, D9, D10, and wherein the effect of D9, D10 is to influence each other when preventing the magnetic valve 3 at two the public pressure-reducing valve of pulse igniter 2 places.
The structure of gas double kitchen range is: left and right sides kitchen range has structure identical but independently pulse igniter, magnetic valve separately, about the magnetic valve 3 (employing parallel way) at the shared baroswitch 4 of two kitchen ranges and pressure-reducing valve 2 places.Because the effect of D9, D10 is arranged, when the gas double kitchen range uses simultaneously, about two kitchen ranges be independent of each other, but, one (as left kitchen range) also using as long as wherein being arranged, the magnetic valve 3 at pressure-reducing valve 2 places is opened all the time, and the keying of another (right kitchen range) is just ineffective to the control of the magnetic valve 3 at pressure-reducing valve 2 places, but does not influence the keying of magnetic valve 5 own, have only when closing left and right sides kitchen range at the same time, the magnetic valve 3 at pressure-reducing valve 2 places is closing passage.If pipeline gas leakage, baroswitch disconnects, and two kitchen ranges all can not be lighted a fire.
(2) control principle of water heater of the present utility model identical with gas range of the present utility model (electrical schematic diagram is identical as Fig. 6), different is: the keying of the microswitch 9 of this water heater is by hydraulic pressure control (function that common water heater itself possesses need not to change).
The difference of this water heater and common water heater is: the pulse igniter more than 7 of this water heater the drive circuit of one-level magnetic valve 3 (forming) by R27, R28, Q10, Q11, D9, D10.Situation during the shared same gas pipe of water heater and gas range is the same with the connection of gas double kitchen range, the magnetic valve 3 at all public pressure-reducing valve 2 places during installation.
(3) the used buzzer of gas range and water heater leakage alarm 11 adopt low-voltages start (+3V), buzzer 11 pipes during power connection.A binding post of one end and baroswitch 4 joins other end ground connection.When pipeline leaked gas, baroswitch 4 placed position 2, and buzzer 11 pipes.
