The electromagnetic type external force starting safe controlling device for gas adopts the structures of the driving magnet and the passive magnet to concentrate a gas opening/closing function, a gas amount regulating function, and a safety protecting function into an integral body. The electromagnetic type external force starting safe controlling device for gas emphasizes that the flow amount of the gas is regulated by the change of external force. The electromagnetic type external force starting safe controlling device for gas still can implement safety protection under the condition that the push rod is not repositioned. The electromagnetic type external force starting safe controlling device for gas has the advantages of simple structure, starting speed, safety protection, quick reaction speed, etc. When the electromagnetic type external force starting safe controlling device for gas is started, great current is not needed, and electricity consumption is saved. The electromagnetic type external force starting safe controlling device for gas is especially suitable for a manual gas device, a semiautomatic gas device, or a full automatic gas device which are supplied with electricity by batteries.
Description
The utility model relates to the control device of combustion gas tool, particularly with gas appliances such as the matching used household gas range of corresponding control circuit, fast water heater, fuel gas heating apparatus, Gas-burning rice pot, baking box in switch, gas quantity regulate the basic control device of control and safeguard protection effect.
Blast tube switch and safety guard most widely used in the present stage domestic combustion gas already have flame-out safety guard of thermocouple and self-priming calutron.The flame-out safety guard of thermocouple is by external force passage component to be pushed into fixed part to make its contact; the thermoelectrical potential that is produced when the flame combustion by thermocouple provides coil current and produces magnetic force; keep two parts attracting states; as meet accident when stopping working, the hot thermocouple electromotive force reduces, and coil current also reduces thereupon; when electric current little to a certain degree the time; the electromagnetic force that produces is kept the incessantly attracting state of passage component, makes it break away from fixed body and sets back, and closes blast tube.Do not need power consumption though this device has control circuit, application of force push rod must reset after release, and operating mechanism is complicated, the manufacture process requirement height, thus the cost height, and only have slow switching function, can not regulate its channel capacity, so only be used for manually operated combustion gas tool.Self-priming calutron is to provide coil by heavy current, makes it produce magnetic field force, and blast tube is opened, and reduces electric current after a period of time, and it is maintained the statusquo.The excision electric current, magnetic field force disappears, and setting back is closing passage.Though this device opening speed is very fast, has the manufacturing cost height equally, need complicated control circuit, and starting current is big, power consumption is big, and battery life is short, its function singleness, have only the switching function, do not have the channel capacity of adjusting function, be applicable to manually or semi-automatic operation combustion gas tool.
The purpose of this utility model is to avoid the existing in prior technology defective and provides a kind of combustion gas open and close, gas quantity of collecting to regulate the electromagnetic type external force that control and safeguard protection act on one and start the gas safe control device.
The utility model is achieved by the following scheme: coiling on the skeleton in the shell, be fixed on the shell inner end decide between magnet and the skeleton magnetic shield is housed, having combustion gas advances, the valve body of outlet and gas sealing pad is fixed by drive end bearing bracket and shell, on each faying face sealing ring is housed, prevent the gas leakage contaminated environment, this control device has the valve opening and closing mechanism that external force starts, comprise that active magnet and push rod head close-fitting are pressed into, the passive magnet that is contained in the magnetic shield is sleeved on slip on the push rod, form adhesive face with the active magnetic body, because the blast tube sealing gasket is sleeved on the passive magnet, do the time spent in no external force, the output of control circuit no current, coil no current is not by promptly there being magnetic force, and initiatively magnet and passive magnet are fitted mutually under spring action and made the blast tube sealing gasket be close to channel end surface and be in closed condition.When external force puts on push rod and control circuit and produces magnetic force to the coil input current, initiatively magnet moves to left, against the force of the spring under adhesive face magneticaction, passive magnet is moved to left by suction, drive blast tube sealing gasket moves to left synchronously and opens the blast tube valve port, and the open amount of blast tube is proportional with the external force size.
In a single day when in combustion process, accident extinguishing, anoxic or superheating phenomenon occurring; control circuit cuts off coil power supply voluntarily; adhesive face place magnetic force disappears; passive magnet moves to right under spring action and sets back; make the blast tube sealing gasket be close to the blast tube face and closing passage, reach the purpose of safeguard protection, at this moment; though it is that push rod does not reset that external force still keeps, and does not influence closing of blast tube.When external force disappeared, under two spring actions, initiatively magnet and passive magnet resetted and move to right, and close blast tube.
The defective that this control device has overcome the prior art function singleness has realized the combustion gas open and close.Gas quantity is regulated the multifunctional characteristics of control and safeguard protection effect, makes people's other work of can feeling at ease to be engaged in when cooking, can not burn out kitchen range because of forgeing, and also can not cause accidents such as fire because of the accident fire extinguishing.Also have simple in structure, opening speed and the fast characteristics of safeguard protection reaction speed, under little electric current, work, the power consumptive province, battery life is long, is applicable to the combustion gas tool of battery powered manual, semi or fully automatic control.
Accompanying drawing 1 provides structural representation of the present utility model.
By above-mentioned accompanying drawing embodiment the utility model is described in detail again.
