Abstract
The utility model relates to a special isopiestic cutting torch for gasoline and oxygen cutting machines, which belongs to the technical field of machine work and is composed of a gasoline valve, a gasoline tube, a cutting tip body, a cutting oxygen tube, a preheating oxygen tube, a preheating oxygen valve, a cutting oxygen valve, a cutting tip, etc. A tubule is arranged in the gasoline tube, one end of the tubule is connected with a cutting tip body, and the other end of the tubule is connected with the cutting tip. When the gasoline flows to the cutting tip from the cutting tip body through the tubule in the gasoline tube, the head losses everywhere in the gasoline tube are approximately equal, so that the flame of the cutting torch can be kept stable in any position. Meanwhile, the gasoline valve has fine threads of which the thread pitch is below 0.5mm, and the flow rate of the gasoline can be effectively adjusted.
Description
The utility model relates to the isobaric cutting torch of a kind of gasoline oxygen cutter special use, belongs to the Machining Technology field.
At present, can be used to cut low carbon steel plate below 60 millimeters by the gasoline oxygen cutter of inventor application, the used cutting torch of this cutting machine is special-purpose cutting torch, and obtained China Patent Right, the patent No. 92225731.0, used cutting torch is to change the acetylene gas pipe on the existing isobaric cutting torch into gasoline pipeline, its shortcoming is because caliber is too big, using gasoline--when the oxygen torch carries out cutting operation, along with the diverse location of cutting torch in hand changes (put down, stand, face upward), flame alters a great deal, even extinguishes.This has just had a strong impact on the practicality of portable gasoline oxygen cutter.
The purpose of this utility model is the special-purpose cutting torch of a kind of novel gasoline oxygen cutter of design, change the wherein structure of gasoline pipe, when liquid gasoline was passed through in cutting torch, its pressure drop equated everywhere, thereby when overcoming the change of cutting torch location status, gasoline--the problem of oxygen flame working conditions change.
Content of the present utility model is that the special-purpose isobaric cutting torch of gasoline oxygen cutter partly is made up of petrol cock, gasoline pipe, cutting torch body, cutting oxygen pipe, preheat oxygen pipe, preheating oxygen valve, cutting oxygen valve door and cutting torch etc.Be provided with a tubule in the gasoline pipe, an end of tubule connects with the cutting torch body, and the other end connects with cutting torch.Gasoline from the cutting torch body by the tubule flow the gasoline pipe to cutting torch, the oil pipe inner ram loses everywhere about equally, thereby cutting torch flame can all keep stable in any position.Simultaneously, petrol cock is that pitch is the fine thread below 0.5 millimeter, so that the flow of gasoline is effectively regulated and controlled.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is first embodiment of gasoline pipe in the isobaric cutting torch.
Fig. 3 is second embodiment of gasoline pipe in the isobaric cutting torch.
Fig. 4 is the A-A cutaway view of Fig. 3.
Fig. 5 is the 3rd embodiment of gasoline pipe in the isobaric cutting torch.
Below in conjunction with accompanying drawing, introduce content of the present utility model and embodiment in detail.Among Fig. 1, the 1st, petrol cock, the 2nd, gasoline pipe, the 3rd, gasoline pipe, its structure is identical with gasoline pipe 2.The 4th, preheat oxygen tracheae, the 5th, cutting oxygen pipe, the 6th, preheating oxygen valve, the 7th, cutting oxygen valve door, the 8th, cutting torch, the 9th, cutting torch body.Among Fig. 2, the 3rd, gasoline pipe, the 10th, the tubule in the middle of the gasoline pipe, its diameter is 0.8～1.0 millimeter, present embodiment is got 0.9 millimeter.Tubule is fixed in the gasoline pipe by retainer ring 11, tubule two ends respectively with cutting torch body and cutting torch in gasoline pipe link.Fig. 3 is second embodiment of the present utility model, among the figure, and the 12nd, fill in the metal bar in the gasoline pipe, its surface has a groove 13(as shown in Figure 4), the sectional area of groove is 0.5～0.8 square millimeter, present embodiment is got 0.7 millimeter.Solid bar becomes tight fit with gasoline pipe, and two ends link with cutting torch body and cutting torch respectively.Therefore when gasoline from the cutting torch bulk flow during to cutting torch, can only be by the groove (that is tubule) of metal bar, thus make the loss in head in the gasoline pipe equal everywhere.Fig. 5 is another embodiment, among the figure, and the 14th, choked flow rod, the 15th, boss, the 16th, tubule, the 3rd, gasoline pipe.Choked flow rod 14 to be shaped as two ends thin, middle thick, being equipped with diameter from the center, two of thin segment along warp-wise is 0.8～1.0 millimeter aperture 16, i.e. tubule in the gasoline pipe.In the present embodiment, hole diameter is 0.9 millimeter.Also to be equipped with two diameters be 0.8～1.0 millimeter aperture in the appropriate location of thick section in the centre, and the hole diameter of present embodiment is 0.9 millimeter.This aperture one end communicates with the radial hole of thin end, and the other end communicates with gap between choked flow excellent 14 and the gasoline pipe, and this gap is 0.05～0.08 millimeter, and present embodiment is got 0.08 millimeter.There are two boss 15 at the both ends of the butt end of choked flow rod, become tight fit between boss 15 and the gasoline pipe, and two thin ends of choked flow rod link with cutting torch body and cutting torch respectively.Therefore, when gasoline from the cutting torch bulk flow during to cutting torch, gasoline at first along the aperture of choked flow rod thin segment earlier the footpath backward longitudinal stream advance in the gap of choked flow rod and gasoline pipe, again from the aperture of the other end earlier vertically the back radial flow reach the identical purpose of gasoline pipe inner ram loss everywhere to cutting torch.
