Abstract
The utility model relates to a preheating device for a liquid fuel range, in which a housing with a gas inlet hole on the cylindrical surrounding walls of the opening is fixed on the body of the preheating device, a flow control bar, a control joint and a filling bar are arranged in the hole of the body of the preheating device, a locking nut is screwed on the control joint, a nipple communicates the control joint and a liquid conveying tube, the joint is arranged on the body of the preheating device, and a hole of the joint is communicated with the hole for containing the flow control bar through the hole for containing the filling bar. The utility model has the advantages of simple structure, capacity of flow control of the preheated liquid, favorable fuel firing effect, no production of red fire and black smoke, convenient and reliable use and is suitable for being used as the preheating device for a liquid fuel range.
Description
The utility model relates to a kind of preheating device of liquid fuel cooker.
The existing cooking stove that uses liquid fuel, direct combustion of liquid fuel heating generating tube is adopted in the preheating of its liquid fuel mostly, this preheating method is easy to generate flourishing and black smoke, more obvious when particularly burning the high heating value liquid fuel, though also have some liquid fuel cookers also to adopt some smoke consuming apparatuses, flourishing and black smoke still appears in cooking stove combustion system easily under the temperature condition with higher.
The purpose of this utility model provides a kind ofly can control preheating with liquid fuel flow and combustion efficiency liquid fuel cooker preheating device preferably.
Task of the present utility model realizes with following mode: a kind of liquid fuel cooker preheating device is to be fixed with cover on the preheating device body, through hole one end in the preheating device body is equipped with the control joint, the other end flow-control bar of packing into, the awl point of flow-control bar is facing to the end face of control joint, collar nut is connected woven hose with the control joint, the woven hose other end stretches in the cover, another through hole is equipped with and fills out bar in the preheating device body, the hole of filling bar is connected with the aperture intercommunicating pore of dress flow-control bar, joint is contained on the preheating device body, through hole in it is connected with the hole of filling bar, on the uncovered cylindrical periphery-wall of cover air admission hole is arranged.Air admission hole is the combination in hole or slit or hole and slit.The material of making preheating device body and flow-control bar is the material of two kinds of different linear expansion coefficients, and the line of material coefficient of expansion of flow-control bar is bigger than the line of material coefficient of expansion of preheating device body.
The utlity model has simple in structure, the preheated liquid flow can be controlled, fuel combustion efficiency does not well produce flourishing and black smoke, characteristics such as easy to use, reliable, is suitable for the preheating device of making liquid fuel cooking range.
The front view of this preheating device of Fig. 1 embodiment two
Fig. 2 is the vertical view of Fig. 1
Fig. 3 is the side view of Fig. 1
Below in conjunction with accompanying drawing the utility model is described in further detail.Present embodiment is:
Cover 1 is one and is bent into the uncovered tin of a no end with sheet metal, be furnished with 20 to 150 air admission holes 13 on the perisporium of tube.Cover 1 is fixed on on steel or the castiron preheating device body 2, and flow-control bar 3 spinnings are in the through hole of preheating device body 2, and locking nut 5 is spun on the control joint 4, and control joint 4 is spun in the through hole of preheating device body 2, and locking locking nut 5.Collar nut 6 is fixed on woven hose 7 on the control joint 4.Fill out in the hole that bar 10 is contained in preheating device body 2, its afterbody is equipped with joint 9, and its head has intercommunicating pore 14 to be connected with the holes of dress flow-control bars 3.Spray point 8 is fixed on the preheating device body 2, and woven hose 7 terminations are stretched in the cover 1.Screw 11, screw 12 are used for stopping up machining hole.
Flow-control bar 3 flows through liquid fuel with to fill out bar 10 all gapped with its installing hole in the gap.
Use: with reference to accompanying drawing, during the kitchen range preheating, pre-heating fuel enters from joint 9, just can enter the awl point of flow-control bar 3 and slit that the aperture on the control joint 4 forms again in woven hose 7 enters cover 1 through intercommunicating pore 14 again behind the gap that forms through the endoporus of filling out bar 10 and preheating device body 2.Thereby liquid fuel long flow path on burner body 2, be subjected to preheating time longer, the preheated liquid temperature is comparatively high, helps burning.Spray point 8 is contained in the generating tube of preheating device top to kitchen range (accompanying drawing does not mark entering ignited fuel in the cover 1, omit) carry out preheating, because a lot of air admission holes 13 that replenish air are arranged on the cover 1, so over-emitting black exhaust and flourishing can well eliminate fuel combustion the time.During preheating, whole preheating device also obtains heating, when the fiery normal combustion of master, also can heat preheating device.As after closing main fire, need again to continue again to use at once, preheating device temperature this moment is than higher, if pre-heating fuel enters cover 1 very soon, fuel can be vaporized after running into hot preheating device body 2 at once, produce a large amount of fuel vapours, cover 1 can not in time replenish a large amount of air, flourishing and over-emitting black exhaust can occur.So preheating this moment will slowly enter in the cover 1 with fuel, fuel flow rate must reduce, after the preheater temperature raises, the preheating device body 2 that flow-control bar 3 that copper material is made and steel are made produces linear expansion simultaneously, because the linear expansion coefficient of flow-control bar 3 is greater than the linear expansion coefficient of preheating device body 2, so the linear expansion amount of flow-control bar 3 is greater than preheating device body 2, thereby formed slit diminishes between the awl of flow-control bar 3 point and the control joint 4, the pre-heating fuel flow reduces, and has played the purpose that varies with temperature automatic control pre-heating fuel flow.The height of control temperature can be adjusted by the size of regulating the initial slit between flow-control bar 3 and the control joint 4.
