Abstract
The utility model discloses a low-voltage safe gas valve without an external electric source. Once the fire or the gas leakage happens, the gas valve is turned off automatically, and then cuts off gas source. In this way, the user's safety is guaranteed. The utility model comprises a valve body, a hand knob and a sealing plate. A pulling haft and a pulling are integrated into a whole, one end of which is fixed with a sealing cushion. A sliding cap and an upper magnet ring are connected together and arranged on the excircle of the upper bracket. A magnet coil is hitched outside the magnet ring. Output of a controlling device which is comprised of a gas siren, a boosted circuit and a capacitance charge and discharge circuit, is connected to the magnet coil. When the gas leakage or the fire happens, the low-voltage safe gas valve will be turned off automatically, and the air source is cut off as well to guarantee the user's safety. In addition, the battery can keep on working more than one year. The utility model overcomes the shortage that the high-tension electricity is power off because of fire disaster and the valve can not work normally.
Description
Technical field
The utility model belongs to the gas valve scope, does not particularly use the external force power supply, and gas valve is closed automatically when the condition of a fire taking place or gas leakage is arranged, and cuts off source of the gas, a kind of low-voltage safety gas valve of protection user security.
Background technique
The widely-used social progress and the process of urban modernization represented of combustion gas, it has significantly reduced the degree of urban air pollution, brings great convenience and efficient to people.Yet, people are when enjoying the convenient combustion gas of cleaning, also in various degree brought many disasters, the harm that causes because of combustion gas grows with each passing day, the loss that causes to people's lives and properties is an immeasurable problem especially, and it is compared with the general coal-fired fire that takes place, and is difficult for discovering, have more sudden, danger.
At the problems referred to above, many enterprises have released the device that is used for gas alarm, but most of product is passive warning type, and warning device and gas valve are installed separately, and can only report to the police, and can not further close combustion gas when reporting to the police, and hidden danger still exists; There are some external products when reporting to the police, to close combustion gas at present, its alarm links to each other with the drive unit of gas valve, by mains-supplied, but this class warning product all must just can be worked when electric power is arranged, therefore very inconvenient, often take place unregulated power to supply with and when causing fire to take place and the idle phenomenon of warning product, and price is higher, is difficult for popularizing.
Summary of the invention
The purpose of this utility model provides a kind of low-voltage safety gas valve, described safe gas valve generally is made up of valve body, handle, sealing gasket, this gas valve is fixed with seal rubber pad 8 in the termination of the pull handle 1 that fuses, pull bar 2, magnet ring 7 under the phase embedding between valve body 11 and the support 15, pressure spring 9 is enclosed between the following magnet ring 7 and seal rubber pad 8 on the pull bar 2, and pull bar 2 can axially slide up and down in support 15; It is characterized in that: on support 15 upper end cylindricals, be with sliding cap 4, upper magnetic ring 5 is attached thereto together, electromagnetic coil 6 is enclosed within two magnet ring outsides, ball 3 is stuck on the groove 16 of pull handle 1 upper end and support 15 walls in the corresponding hole, and ball 3 can stretch out in the triangular groove 17 that a part snaps in sliding cap 4 inwalls from this hole; By gas alarm 14, booster circuit 13, the output and the electromagnetic coil 6 of the control gear that capacitor charge and discharge circuit 12 is formed join.
Described gas alarm 14 is battery-powered.
Described booster circuit 13 is the high-frequency step-up transformer formula.
In case the beneficial effects of the utility model are this low-voltage safety gas valve gas leakages or when having fire alarm to take place, and just can close automatically, cut off source of the gas, guarantee user security.In addition, the safety gas valve does not use high-tension electricity, a use itself with battery just can guarantee proper functioning more than 1 year, prevented the blackout that when the condition of a fire takes place, causes and the inoperable drawback of safe gas valve.Owing to used booster circuit, significantly reduce the volume of electromagnetic coil power supply electric capacity, make the total volume of valve reduce many; The sliding cap structure, with less strength just can control valve close, reduced the power of control circuit, make control circuit simple; Adopt electromagnetic coil to attract the structure of magnet ring, increased the attraction force of magnetic force, guaranteed that valve works reliably.

Embodiment
The purpose of this utility model provides a kind of low-voltage safety gas valve, described safe gas valve generally is made up of valve body, handle, sealing gasket, this gas valve is fixed with seal rubber pad 8 in the termination of the pull handle 1 that fuses, pull bar 2, magnet ring 7 under the phase embedding between valve body 11 and the support 15, pressure spring 9 is enclosed between the following magnet ring 7 and seal rubber pad 8 on the pull bar 2, and pull bar 2 can axially slide up and down in support 15; On support 15 upper end cylindricals, be with sliding cap 4, upper magnetic ring 5 is attached thereto together, electromagnetic coil 6 is enclosed within two magnet ring outsides, ball 3 is stuck on the latching slot 16 of pull handle 1 upper end and support 15 walls in the corresponding hole, and ball 3 can stretch out in the triangular groove 17 that a part snaps in sliding cap 4 inwalls from this hole; The output and the electromagnetic coil 6 of the control gear that battery-powered gas alarm 14, high-frequency step-up transformer formula booster circuit 13 and capacitor charge and discharge circuit 12 are formed join.Working principle with safe gas valve is further specified the utility model below.
When valve installs, install battery, the oscillating circuit of the gas alarm 14 of control gear is started working, the high-frequency voltage of output boosts the back to capacitor charge and discharge circuit 12 chargings through high frequency transformer formula booster circuit 13, after voltage reaches rating value, the oscillating circuit of the gas alarm 14 of control gear quits work, and electric capacity stops charging; When if the voltage of electric capacity is lower than lower limit, oscillating circuit restarts to the electric capacity charging, makes the electric weight of electric capacity remain on saturated state forever.Manually upwards spur pull handle 1 when Open valve, promote upper magnetic ring 5 at following magnet ring 7 magnetic force sliding cap 4 is moved upward, extruding ball 3 moves inward on tightly the latching slot that is pressed in valve pull rod 2 16; After manually unclamping pull handle 1, ball 3 can't outwards move under the effect of sliding cap 4 and make valve remain on opening state.When gas leakage or when having the condition of a fire to take place, gas warning system 14 disconnects booster circuit 13, capacitor charge and discharge circuit 12 is by electromagnetic coil 6 discharges, at the electromagnetic coil 6 inner magnet rings 5 that produce opposite magnetic fields attraction sliding cap, sliding cap 4 is moved downward discharge ball 3, valve pull rod 2 makes valve closing moving downward under the effect of pressure spring 9 on the seal ring 10 that seal rubber pad 8 is depressed into valve body 11.So circulation, the control gear that battery-powered gas alarm 14, high-frequency step-up transformer formula booster circuit 13 and capacitor charge and discharge circuit 12 are formed reaches the purpose of automatic control low-voltage safety gas valve automatic self-closing gas valve when safety fuel gas hidden danger occurring.Overcome the weakness that relies on civil power electric power in the prior art.
