Fig. 4 shows the simplified schematic diagram of utilizing the utility model valve to control a plurality of combustion gas terminals, HG1, HG2 and HG3 represent the flame sensor switch of each combustion gas terminal (as gas cooker and water heater) respectively among the figure, and ZX1, ZX2 and ZX3 represent the ignition knob switch of aforementioned each combustion gas terminal respectively; The utility model will be controlled the safe handling of a plurality of combustion gas terminals with a valve, has realized that a valve controls a plurality of combustion gas terminals.During proper functioning, each combustion gas terminal is not all disturbed.When the situation of accident extinguishing appears in any one terminal, the fuel gas source of whole family will all be cut off.
As for how realizing the utility model valve opening and the control circuit of closing, adopt technological means habitual in the present technique field to realize, Fig. 5 only shows an embodiment of valve controling circuit, wherein, JP1 and JP11 are ABAP Adapter terminal (JP1 wherein is the electromagnet power supply, and JP11 is single chip computer AT 89S51 power supply); JP2, JP3 and JP4 are electromagnet, and DL1, DL2 and DL3 are Darlington transistor, and U1 is a single-chip microcomputer, and this single-chip microcomputer adopts the AT89S51 single-chip microcomputer.
The utility model household gas range valve mechanism is applied to control in family's combustion gas using process (having gas cooker and gas water-heater simultaneously with family is the example explanation) comprises automatic unlatching and close two actions automatically, having closed automatically wherein normally closed and the improper two states of closing, and narrates the exercises of valve below respectively:
The breakdown action of valve is: the user opens any one among three ignition knob switch ZX1, ZX2, the ZX3 arbitrarily, the ff pin output high level of single chip computer AT 89S51, Darlington transistor DL4 conducting, electric current flows through the 3rd electromagnet JP2 (among Fig. 1 shown in the reference character 19), the 3rd electromagnet JP2 promotes valve core of auxiliary valve 3, combustion gas is by secondary valve point combustion flame, the operation of the control program control entire circuit in the single chip computer AT 89S51 (can be set to 2 seconds) after a while and send the 3rd electromagnet JP2 cut-offing instruction.Behind the circuit delay 2 seconds, the 3rd electromagnet JP2 outage, secondary valve cuts out automatically.This moment, flame made among three flame sensor switch HG1, HG2, the HG3 and corresponding that closure of secondary valve, the flame sensor switch sends low level to single chip computer AT 89S51, the zf1 pin output high level of single chip computer AT 89S51, Darlington transistor DL3 conducting, electric current flows through the first electromagnet JP3 (shown in reference character among Fig. 1 13), and the first electromagnet JP3 promotes valve core of main valve 15 combustion gas and makes the flame holding burning by main valve.After this, the state of other two ignition knob switches does not exert an influence to the main valve of having opened.
The normal closing motion of valve is: close among three ignition knob switch ZX1, ZX2, the ZX3 any one or several, wherein with the corresponding flame sensor switch of each switch HG1, HG2, send signal when HG3 senses signal immediately and give single chip computer AT 89S51, the gzf pin output high level of single chip computer AT 89S51, two Darlington transistor DL1, DL2 associating conducting, electric current flows through the second electromagnet JP4 (shown in reference character among Fig. 1 1), closes main valve thereby control this second electromagnet JP4.
When making flame extinction: as flame sensor switch HG1 when something unexpected happened, HG2, as long as an induction is arranged among the HG3 less than the existence that flame is arranged, this flame sensor switch disconnects at once, when the ignition knob switch corresponding with it still is in closed state, the zf2 pin output high level of single chip computer AT 89S51, Darlington transistor DL1 conducting, before this, Darlington transistor DL2 is on state all the time, electric current flows through the second electromagnet JP4, second electromagnet promotes valve core of main valve 15, closes the total inlet pipe road, makes flame extinction, this moment, valve closing did not have combustion gas to enter in the man.Because electromagnet should not be switched on for a long time, the control program in the single chip computer AT 89S51 is controlled to second electromagnet JP4 power supply 2 seconds, and DL2 ends by Darlington transistor, second electromagnet JP4 outage.
Because the utility model valve has said structure, therefore have following several respects characteristics: (1) valve adopts the Normally closed type structure, and when not using combustion gas, valve keeps closing; (2) can realize utilizing flame to come the open and close of control valve; (3) valve is installed in ingress in the fuel gas pipeline inlet chamber, can guarantees indoor safety with the combustion gas terminal; (4) adopt major and minor valve two-part structure, guarantee that the combustion gas terminal is held open state when needing flame; (5) valve is provided with hand push button, when having a power failure, also can uses; (6) each combustion gas terminal of family is used this valve simultaneously, can realize guaranteeing each combustion gas terminal security in the whole family, using combustion gas easily with a valve, and its using scope is wider.In addition, valve each several part mechanical development can be become modular organization, be convenient to and being connected of combustion gas terminal; (7) when valve is developed as product, its cost is about 300 yuan, and its cost performance is compared with existing like product has very big advantage.
Although in conjunction with figure the utility model is described above; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment only is schematic; rather than it is restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; under the situation that does not break away from the utility model aim, can also make a lot of distortion, these all belong within the protection of the present utility model.
