Abstract
A novel safety gas valve for coal gas comprises a safety gas valve body and a control circuit. An electromagnet, a power indicator light, an automatic reset switch and a manual reset switch are arranged in the control circuit and are in sequential and parallel connection. The safety gas valve body is mounted on a gas pipeline connecting port. One end of the safety gas valve body is provided with a handle body. A spring is arranged between the handle body and the gas pipeline connecting port. The handle body is made of ferromagnetic materials and located on one side of the electromagnet in the control circuit. The novel safety gas valve for the coal gas is simple in structure, safe, reliable and wide in application range, and eliminates the gas leakage phenomenon caused by abnormal extinguishing of the coal gas when nobody is on guard, and other safety accidents due to gas leakage.
Description
Technical field
The utility model relates to a kind of gas safety air valve, is specially a kind of novel gas safety air vavle.
Background technique
At present, traditional coal gas using method is the manual unlocking jet at first, and electronic striking is lighted coal gas, usually under personnel's keeping an eye on, the coal gas of lighting extinguishes in improper situation, must close immediately jet, avoid gas leakage, and gas leakage causes security incident.Keep an eye on if personnel forget, the coal gas of lighting extinguishes in improper situation, jet or open mode, and like this, coal gas can leak always under the unmanned situation of finding, leaks into to a certain degree to cause security incident.
The model utility content
The technical problem that the utility model solves is to provide a kind of novel gas safety air vavle, the problem that causes security incident to solve coal gas causes under the unattended state gas leakage and gas leakage in improper situation.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of novel gas safety air vavle comprises safety air vavle and control circuit, is provided with the electromagnet, power supply indicator, automatic reset switch, the manual reset switch that are connected in parallel successively in the described control circuit; Described safety air vavle is installed on the gas pipe line connection mouth, and safety air vavle one end is provided with the handle body, is provided with spring between described handle body and the gas pipe line connection mouth, and described handle body adopts ferromagnetic substance, and the handle body is arranged in electromagnet one side of control circuit.
As a kind of optimization of above technology, described automatic reset switch, manual reset switch are equipped with temperature transducer, and described automatic reset switch is near apart from burning things which may cause a fire disaster, and described manual reset switch is far away apart from burning things which may cause a fire disaster.
Beneficial effect:
Compared with prior art, the utility model is simple in structure, and is safe and reliable, applied range; Eliminated that undesired the extinguishing of coal gas causes gas leakage when unattended, and other cause security incident because of gas leakage.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, safety air vavle, 11, the handle body, 12, spring, 2, the gas pipe line connection mouth, 3, electromagnet, 4, power supply indicator, 5, automatic reset switch, 6, manual reset switch.
Embodiment
In order to make realization technological means of the present utility model, creation characteristic, to reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of novel gas safety air vavle comprises safety air vavle 1 and control circuit, is provided with the electromagnet 3, power supply indicator 4, automatic reset switch 5, the manual reset switch 6 that are connected in parallel successively in the described control circuit; Described safety air vavle 1 is installed on the gas pipe line connection mouth 2, safety air vavle 1 one ends are provided with handle body 11, be provided with spring 12 between described handle body 11 and the gas pipe line connection mouth 2, described handle body 11 adopts ferromagnetic substance, and handle body 11 is arranged in electromagnet 3 one sides of control circuit.
Described automatic reset switch 5, manual reset switch 6 are equipped with temperature transducer, and described automatic reset switch 5 is near apart from burning things which may cause a fire disaster, and described manual reset switch 6 is far away apart from burning things which may cause a fire disaster.
At first, with the control circuit plugged, closed manual reset switch 6, at this moment power supply indicator 4 is bright in the control circuit, electromagnet 3 energisings, produce magnetic, under the magnetic action of electromagnet 3, hold the handle body 11 of safety air vavle 1, safety air vavle 1 is opened, gas pipe line is opened, and coal gas just can normal combustion; When the temperature transducer collection burning things which may cause a fire disaster temperature of manual reset switch 6 was higher than 40 ℃, when the temperature transducer collection burning things which may cause a fire disaster temperature of automatic reset switch 5 was higher than 80 ℃, manual reset switch 6 disconnected, and automatic reset switch 5 is connected simultaneously, coal gas continuation normal combustion.When transient cause with flame extinction, gas leakage, the temperature transducer collecting temperature of automatic reset switch 5 is lower than 80 ℃, automatic reset switch 5 disconnects, electromagnet 3 does not produce magnetic, handle body 11 breaks away from electromagnet 3 under the pulling force effect of spring 12, safety air vavle 1 is closed, and breaks off coal gas and communicates with the external world and cause coal gas gas leakage.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.Claimed scope of the present utility model is defined by appending claims and equivalent thereof.
