Abstract
The utility model provides a novel gas shutoff magnetic self-locking device which is characterized in that a switch is installed on a magnetic support frame, a spring supports the magnetic support frame, and a balance weight hammer is installed at the tail end of an air valve. The air valve is installed on a valve core, the valve core is connected to a valve core body through threads, the valve core body is connected to a main valve body through threads, a filter screen is connected in a main air inlet channel through threads, the top of the main valve body is connected with an air outlet channel through threads, the air outlet channel is connected with a gas stove through a rubber pipe, a plurality of air inlet channels are uniformly distributed on the valve core, the upper portion of the valve core body is provided with a gas vent, the bottom of the main valve body is provided with a magnet and the magnetic support frame, and a clamp spring is installed in a clamp spring groove. The novel gas shutoff magnetic self-locking device has the advantages of being novel in structure, simple in a process, and strong in practicability. According to the novel gas shutoff magnetic self-locking device, gas leakage can be effectively prevented, and meanwhile life safety of people can also be guaranteed.
Description
Technical field
The utility model relates to a kind of gas leakage self-closing device, and particularly a kind of novel gas is closed the magnetic self-locking device.
Background technique
In long-living work of day, a lot of families only close the switch of gas cooker in using gas process, be reluctant to close main gas valve, use easily because sebific duct is long-term and wear out, produce potential safety hazard, cause gas leakage, and danger just is easy to occur in this link, not only brings irremediable loss to oneself, and, also can bring disaster to neighbours, even can make people's life be subject to danger.
Summary of the invention
The purpose of this utility model is the deficiency that exists in the above-mentioned technology, provides a kind of novel gas to close the magnetic self-locking device.It can prevent from not closing because of main gas valve, the gas leakage that the sebific duct fracture causes.
The purpose of this utility model is achieved in that and comprises valve body, magnet carrier, switch, counter weight, it is characterized in that, switch is installed on the carriage of magnet, the spring supporting magnet carrier, and counter weight is installed in the valve tail end.Valve is installed on the spool, spool is with being threaded on the valve core, valve core is with being threaded onto on the main valve body, filter screen is with being threaded in the main air intake,, air outlet channel is connected with gas cooker with sebific duct with the air outlet channel that is threaded on the top of main valve body, a plurality of intake ducts evenly distribute on spool, top at valve core is provided with exhaust port, in the main valve body bottom magnet and magnet carrier is installed, and in the jump ring ditch jump ring is housed.
The utility model has the advantages that, novel structure, technique is simple, and is practical.Can not only effectively prevent gas leakage, and, can also guarantee people's life safety.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing present embodiment is described further:
As shown in Figure 1, switch 1 is installed on the carriage 15 of magnet 3, by spring 2 support brackets 15, counter weight 4 is installed in the tail end of valve 5, valve 5 is installed on the spool 11, spool 11 usefulness are threaded on the valve core 14, valve core 14 usefulness are threaded onto on the main valve body 13, filter screen 12 usefulness are threaded in 9 li of main air intakes, with the air outlet channel 8 that is threaded, with sebific duct air outlet channel 8 are connected to gas cooker on the top of main valve body 13, a plurality of intake ducts 6 evenly distribute on spool 11, be provided with exhaust port 7 on the top of valve core 14, magnet 3 and magnet carrier 15 are installed in main valve body 13 bottoms, jump ring 10 is housed in the jump ring ditch.
Working principle:
During igniting, Drawing switch 1 is screwed gas stove switch simultaneously downwards, counter weight 4 has left the magnetic force scope of strong magnet 3, and combustion gas this moment enters main air intake 9 through filter screen 12 and along intake duct 6 valve 5 blown afloat, and entering gas cooker from exhaust port 7 inflow air outlet channels 8 can light a fire.After point catches fire, can let go.This moment, magnet 3 resetted under the effect of Returnning spring 2, because the pressure of combustion gas blows afloat valve 5 and counter weight 4, counter weight 4 is not in the magnetic force scope, so air feed all the time keeps burning.
When closing, when gas kitchen range flame was closed, combustion gas was not flowed, there is not pressure reduction, valve 5 is under the effect of counter weight 4 deadweights, and free fall seals valve port, this moment, strong magnet 3 was under the effect of Returnning spring 2, reset, counter weight 4 is caught by the magnetic force of strong magnet 3, because of the pressure of magnetic force greater than combustion gas, so under without the effect of external force, can't open, thereby reach the purpose of sealing the gas self-locking.
