Detailed description of the invention
In order to make the purpose of this utility model, design clearer, below in conjunction with embodiment illustrated in fig. 1, nonrestrictive detailed description further to this utility model.
Gas-cooker anti-dry valve described by Fig. 1, mainly includes valve body, temperature sensing device, shell etc., and temperature sensing device is an expanding chamber 3 filling with liquid, and the top of expanding chamber 3 is provided with self-closing liquid injection hole 2, can be used to adding liquid and uses.The side outer wall of expanding chamber 3 is in close contact with the lower surface of steel plate of stove body, with impression from the temperature of stove, in order to increase heat output, this face can be fabricated to fold face, and at the installed position of stove, the shape on surface must be corresponding with this fold face.The inwall of expanding chamber 3 another side is the outside wall surface of moveable expanding chamber piston 4, another outside wall surface of expanding chamber piston 4 is connected through the spool of connecting rod 6 and gas valve is fixing, this spool is the structure of a valve piston 13, the direction being perpendicular to valve piston 13 axis has the through hole 16 that can lead to combustion gas, inlet channel 14 shown in Fig. 1, outlet passageway 15 are the passages of combustion gas, it is evident that when through hole 16 and inlet channel 14, outlet passageway 15 are to timing, combustion gas is passed through, i.e. valve is opened；When through hole 16 misplaces with inlet channel 14, outlet passageway 15, combustion gas can not be passed through, i.e. valve cuts out, as shown in Figure 2.Certainly for the sealing property of guarantee system, 5,12 in figure are sealing rings.
Getting on the bus a groove 7 at connecting rod 6, groove 7 is along the axial excavation of connecting rod 6, and one end groove away from expanding chamber piston 4 is relatively steep, and the position of groove, length and the degree of depth are suitable.
A push rod 10 is laid in the direction that the side of connecting rod 6 fluted 7 is vertical with connecting rod 6, welding catch spring sheet 8 in appropriate location on push rod 10, at catch spring sheet 8 away from the first spring 9 being cased with being compressed on the push rod 10 of connecting rod 6, the other end of the first spring 9 heads on the inwall of this crust of the device 1, the exposed outside at this crust of the device, push rod one end.
Sheet metal 17 is welded in valve body shell body 11 appropriate location, on sheet metal 17 porose, push rod 10 passes through its top rear and just withstands on the side of connecting rod 6 fluted 7, and during normal use stove, push rod 10 withstands under the effect of the first spring 9 not to be had on reeded connecting rod 6 outer surface.
Connecting rod 6 is a hot non-conductor, and its purpose is it is obvious that mainly prevent too much heat from passing to valve body, to prevent from toasting the combustion gas by valve.
Valve piston 13 exposes valve body shell body 11 has certain length, one end of push rod 10 to rest on the end face exposing valve piston 13.On valve piston 13, the corresponding surface of connecting rod 6 has a projection 19, and of the second spring 18 compressed is solidly set on protruding 19, and other one presses closer on the inwall of shell 1.
As another kind of embodiment of the present utility model, the difference of Fig. 3 with Fig. 1 is, remove the valve body part in Fig. 1, and open the through hole passage as combustion gas in expansion piston 4 appropriate location, connecting rod 6 is fixing with piston 4 to be connected, other one of connecting rod 6 is overlapped second spring 18 compressed admittedly, and other one of the second spring 18 presses closer on shell 1 inwall.
During use, temperature-sensitive face of the present utility model being arranged on the lower section being close to kitchen range gas-cooker body steel plate, for ensureing heat transfer efficiency, temperature-sensitive face is in close contact with steel plate；When normally using, not being the highest due to temperature, the liquid in expanding chamber does not seethes with excitement, and insufficient pressure is enough big, so, expanding chamber piston is failure to actuate, combustion gas normal through.Once pot is dryouied, and has reached the temperature set, and the liquid in expanding chamber comes to life vaporization, liquid becomes gaseous state, and expansion chamber pressures increases, and promotes expansion piston motion, by the and then motion of connecting rod valve piston, valve piston through hole misplaces with blast tube, closes combustion gas, during push rod also falls into the groove of connecting rod under the first spring effect simultaneously, now gas-cooker is owing to stopping burning without combustion gas, but expanding chamber temperature is the highest, expansion piston continues motion, and push rod continues to slide in a groove.Final temperature declines, owing to expanding chamber internal pressure reduces, expanding chamber piston moves towards rightabout, when push rod moves to the steeper edge of groove, push rod is made connecting rod stop motion by card, now the through hole of valve piston still misplaces with blast tube, thus avoids the thing generation automatically turning on blast tube in the case of unattended.From structure, only people pulls push rod could depart from groove, and under the double definition of the second spring 18 and push rod, valve piston is in the position of balance conducting.
This utility model simple in construction；Do not use electromagnetic valve, the most just save electric energy, rely on mechanical force to reach the purpose of automatic self-closing gas passage；It is only parts simultaneously, and the repacking for conventional gas stove provides possibility.
It is above an of the present utility model specific embodiment, but those of ordinary skill in the art still can make and still fall within protection domain of the present utility model without departing from scheme of the present utility model.
