Abstract
The invention is a safety gas valve, comprising timer and electromagnetic valve, where gas outlet of the electromagnetic valve is connected with a gas flow sensor, input and output control circuits of the timer are connected with the gas flow sensor and the electromagnetic valve, respectively, a case of the gas flow sensor holds a piston whose lower end is provided with a pull spring and whose upper end is provided with a magnet, the upper end of the case is provided with a magnetic switch provided with a magnet, and the case is non-antimagnetic. And it can be automatically turned off in the set time to cut off gas source, assuring gas use safety.
Description
Technical field
The invention belongs to combustion gas gas circuit control technique field, particularly relate to a kind of safety air vavle that domestic gas uses.
Background technique
At present, combustion medium is done by most of families all using gases, as liquid gas, coal gas or rock gas.When using up burner, people can close the burner valve, but the time regular meeting forget and close gas source valve that if fuel gas pipeline or burner leak gas, consequence will be hardly imaginable so.At present, prior art does not have to control automatically and to close the valve of source of the gas.
Summary of the invention
The purpose of this invention is to provide a kind of automatic control and close the safety air vavle of source of the gas.
The technical solution used in the present invention is: safety air vavle comprises electronic timer and solenoid valve, the air outlet of solenoid valve is connected with the gas flow inductor, and the input control line road of electronic timer and output control lines link with gas flow inductor, solenoid valve respectively;
In the shell of gas flow inductor piston is housed, extension spring is equipped with in the piston lower end, and magnet is equipped with in the piston upper end, and the moving switch of magnetic is equipped with in the shell upper end, on the moving switch of magnetic magnet is housed;
The shell of gas flow inductor is NULL not.
The invention has the beneficial effects as follows: when not closing gas source valve when not using combustion gas, safety air vavle can be closed in the time of setting automatically, cuts off source of the gas, thereby avoids fuel gas pipeline or burner gas leakage, ensures and uses gas safety.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the structural representation of gas flow inductor among Fig. 1.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, the present invention is made up of gas flow inductor 1, electronic timer 2, solenoid valve 3.The effect of gas flow inductor 1 is to be used for signal piping whether gas flow to be arranged and send signal to electronic timer 2; The effect of electronic timer 2 is that gas circuit is opened or closed to control electromagnetic valve 3, when the temporary close burner, writing time and control electromagnetic valve 3 are in opening state in the time of setting, avoid frequently opening safety air vavle because of the Temporarily Closed burner and bring trouble in the use to people; The effect of solenoid valve 3 is to open or close gas circuit under the control of electronic timer 2.
As shown in Figure 2, in the shell 7 of gas flow inductor piston 10 is housed, extension spring 11 is equipped with in piston 10 lower ends, and magnet 9 is equipped with in piston 10 upper ends, and shell 7 upper ends are equipped with on the moving switch 6 of magnetic, the moving switch 6 of magnetic magnet 8 is housed; The shell 7 of gas flow inductor 1 is NULL not.
Working principle of the present invention is: safety air vavle is installed in the pipeline of gas source valve lower end, when opening gas source valve (gas cylinder or burning line master control valve), press the switch knob on the safety air vavle, at this moment, safety air vavle is in opening state, and electronic timer is in time status, does not have gas flow in the pipeline, piston 10 is between suction port 12 and the air outlet 13, and is gapped between piston 10 and the shell 7; When opening burner and use gas, gas enters cylinder 14 by suction port 12 and is flowed out by air outlet 13, the gas pressure of suction port 12 is greater than the gas pressure of air outlet 13, cylinder 14 internal air pressures are in non-equilibrium state, act on the pulling force sum of the gas pressure of piston 10 belows greater than gas pressure that acts on piston 10 tops and extension spring 11, under the gas pressure effect, piston 10 moves up, be in the upper end of air outlet 13 until the lower end of piston 10, because magnet 9,8 polarity are relative, under the effect of same sex phase repulsive force, magnet 9 promotes magnet 8 and moves up, and until moving switch 6 closures of magnetic, thereby will have the signal of gas flow to pass to electronic timer 2, at this moment, electronic timer 2 is in not-time state and control electromagnetic valve 3 is in opening state always; After using burner and throttle down, no matter whether close gas source valve, air outlet 13 no gases flow out, gas flows to piston 10 tops by the gap location of piston 10 and shell 7 in the cylinder 14, make cylinder 14 internal air pressures be in state of equilibrium, the gas pressure that acts on piston 10 belows equals to act on the gas pressure of piston 10 tops, piston 10 is under the tension of extension spring 11, move down, because magnet 9,8 distances increase, and the phase repulsive force is not enough to promote magnet 8, the moving switch 6 of magnetic is disconnected, thereby the signal that will not have gas flow is passed to electronic timer 2, and at this moment, electronic timer 2 is in time status and picks up counting automatically, after a period of time (length can be set), gas circuit is closed and cut off to electronic timer 2 control electromagnetic valve 3 automatically, thereby avoid pipeline or burner gas leakage, ensures and use gas safety.
The present invention also can be used for the gas circuit control of other gases.
