Description
Technical field
The present invention relates to a kind of solenoid valve that is used for gas electricity generator, directly use the power supply of generator, need not other distribution source, be particularly suitable for not having the small gas generator of storage battery, belong to the solenoid valve technical field.
Background technique
Because small gas generator exhaust emission is little, the small generator that uses combustion gas to generate electricity is more and more, but generator when unmanned guard if gas leakage easily takes place in fault, cause personal injury, still unresolved at present.In addition, when normal shutdown, also have part residual air long-term existence in the mixing valve, valve is had corrosive action.
Summary of the invention
The objective of the invention is to invent a kind of generator and break down, but autostop, the solenoid valve that is used for gas electricity generator that residual air can use up in the mixing valve when normal shutdown.
For realizing above purpose, technological scheme of the present invention provides a kind of solenoid valve that is used for gas electricity generator, it is characterized in that, by handle, pull bar, magnet, coil, Universal linking lever, rubber column, spring, fuel gas inlet, gas outlet, air intlet, housing, circuit board, power line is formed, coil is located at the upper end in the housing, be provided with pull bar in the middle of the coil, the top of pull bar is passed housing and is connected with handle, press close to the inner walls place in the pull bar upper end and be provided with magnet, the lower end of pull bar is connected with Universal linking lever, the lower end of Universal linking lever connects rubber column, spring is located at outside the Universal linking lever, connect housing and rubber column up and down, fuel gas inlet, gas outlet places the lower end of housing, and rubber column is near fuel gas inlet, air intlet is located at the lower end of pull bar, circuit board is located at one side of housing, is connected with coil, and power line connects generator and circuit board.
Described magnet is strong magnet; Described rubber column is the dual face seals rubber column.
Described circuit board is made up of 2 diode D1 and D2,3 resistance R 1-R3,2 capacitor C 1 and C2,1 triode T1, a controllable silicon SCR 1, electric current enters from the Z1 end, give capacitor C 2 chargings by diode D1, resistance R 3, connect the electromagnetic valve coil end to the Z2 outlet, connect the electromagnetic valve coil end by diode D2, resistance R 1 through triode T1, capacitor C 1, controllable silicon SCR 1 to Z2 outlet simultaneously.
The present invention need not additional power supply, also not charged source itself, not charged on the valve before the small gas generator starts and after starting, valve is only with the power supply that sends after the generator proper functioning, circuit and valve integratedization, be that to open or close all be stable state, need not power supply keeps, live inner walls by strong magnetic during proper functioning, drive the spring handle rubber column and up lift from out fuel gas inlet, and the air intlet of upper end is sealed, circuit board 12 is given coil 4 impulsive current when generator breaks down, producing magnetic field suction pulls down magnet by force, push down rubber column by spring force, fuel gas inlet is sealed, gas electricity generator quits work, and the electric current of solenoid valve outage back shut-off valve provides by the capacitor C 2 in the circuit board, by controllable silicon conducting control, power-off signal promptly triggers the silicon controlled pulse and is controlled by the charging voltage size of capacitor C 1, and this charging voltage is to make the continuous conducting of triode T1 come voltage on the limiting capacitance C1 behind the ac voltage rectifier by solenoid valve, in case the voltage on the outage C1 just rises, and turn-offs solenoid valve thus.
Because air intlet communicated with valve air gate when solenoid valve turn-offed, fuel gas inlet is closed, and fuel gas inlet communicated with gas outlet when solenoid valve was opened, and air intlet is closed, thus when normal shutdown in the solenoid valve residual air can use up.
The present invention also can make combustion gas air inlet hand switch valve, promptly handle is pulled on or depressed the purpose that reaches startup and shutdown with hand.
Advantage of the present invention is:
1. both can make combustion gas air inlet hand switch valve, and have failure safe to cut off function again, convenient and practical.
2. need not to connect power supply in addition, safe and reliable.
3. the remaining combustion gas when the present invention turn-offs in the generator mixing valve can exhaust, and has avoided combustion gas that valve is reached
The corrosion of motor increases the service life.
4. the present invention seals and adopts whole elastomer diaphragm and film bar, zero leakage when guaranteeing to close.
Description of drawings

Fig. 2 is the circuit board schematic diagram.
Embodiment
The invention will be further described below in conjunction with drawings and Examples.
Embodiment
As shown in Figure 1, for being used for the electromagnetic valve structure schematic representation of gas electricity generator, the described solenoid valve that is used for gas electricity generator is made up of handle 1, pull bar 2, magnet 3, coil 4, Universal linking lever 5, rubber column 6, spring 7, fuel gas inlet 8, gas outlet 9, air intlet 10, housing 11, circuit board 12, power line 13.
Coil 4 is loaded on the upper end in the housing 11, load onto pull bar 2 in the middle of the coil 4, press close to top that housing 11 inwall places put magnet 3 back stays 2 passes housing 11 and installs handle 1 in pull bar 2 upper ends, magnet 3 is strong magnet, the lower end of pull bar 2 is connected with Universal linking lever 5, the lower end of Universal linking lever 5 connects rubber column 6, rubber column 6 is the dual face seals rubber column, spring 7 is enclosed within outside the Universal linking lever 5, connect housing 11 and rubber column 6 up and down, fuel gas inlet 8, gas outlet 9 places the lower end of housing 11, rubber column 6 is near fuel gas inlet 8, and air intlet 10 is located at the lower end of pull bar 2, and air intlet 10 communicated with gas outlet 9 when solenoid valve turn-offed, fuel gas inlet 8 is closed, fuel gas inlet 8 communicated with gas outlet 9 when solenoid valve was opened, and air intlet 10 is closed, and circuit board 12 is located at one side of housing 11, be connected with coil 4, power line 13 connects generator and circuit board 12.
As shown in Figure 1, be the circuit board schematic diagram, described circuit board 12 is made up of 2 diode D1 and D2,3 resistance R 1-R3,2 capacitor C 1 and C2,1 triode T1, a controllable silicon SCR 1, Z1 is the low-voltage alternating current power supply input end, Z2 is for connecting the electromagnetic valve coil end, electric current enters from the Z1 end, give capacitor C 2 chargings by diode D1, resistance R 3, connect the electromagnetic valve coil end to the Z2 outlet, connect the electromagnetic valve coil end by diode D2, resistance R 1 through triode T1, capacitor C 1, controllable silicon SCR 1 to Z2 outlet simultaneously.
After solenoid valve is installed in the gas electricity generator suction tude, be to connect with being connected of suction tude and generator.
During manually-operable, handle 1 is upwards moved the top to, combustion gas is delivered to generator by suction port 8 behind the gas outlet 9 and is generated electricity, air intlet 10 is sealed by dual face seals rubber column 6, handle 1 holds after overcoming spring 7 elastic force by strong magnet 3, therefore valve is opened. and can be when valve need cut out manually by handle 1, pull bar 2 is away from strong magnet 3, suction weakens, spring 7 is pushed down fuel gas inlet 8 by dual face seals rubber column 6, combustion gas is turned off, and the generator suction port communicates with air intlet 10, and the combustion gas in pipeline and the solenoid valve can exhaust.
When operating automatically, when generator is worked, ac power supply is charged to C2 by D1, R3, make T1 cycle conducting by D2, R1 simultaneously, limited the voltage of C1, controllable silicon SCR 1 can not be triggered, so solenoid valve is failure to actuate, when generator breaks down, ac power supply is in case disconnect, C1 voltage rises rapidly, controllable silicon SCR 1 conducting, and storage capacitor C2 discharges by electromagnetic valve coil, give coil 4 impulsive current, generation magnetic field suction pulls down handle 1 by force and turn-offs, thereby plays the effect of safety cut-off, closes solenoid valve.
