Abstract
The utility model relates to an LPG card blowtorch, which is composed of an air storing cylinder with a clamping chuck for connecting and a pressure spring air valve, a bonder which is fixedly connected to the air storing cylinder through the clamping chuck, a sprayed air adjusting needle valve which is fixedly connected with the bonder, an air delivery pipe connected with the needle valve, and a flame spraying head which is fixedly connected with the air outlet end of the air delivery pipe. The air passing hole of the bonder and the interface of the air outlet pipe of the air storing cylinder are sealed by a sealing cap with an annular shoulder. The air outlet end of the needle valve is a tapered table shape which is adapted with the shape of the air outlet end of the air delivery pipe. The air outlet end of the needle valve and the air outlet end of the air delivery pipe are connected, and the connecting opening is tightly sealed and pressed by a press ring which is sheathed on the air delivery pipe. The end of the air delivery pipe is enchased with a throat pipe with capillary air outlet holes to make sprayed air disperse evenly and combust completely. The utility model has the advantages of simple structure, low cost, light weight, and convenient operation for holding by hands.
Description
The utility model relates to a kind of hand-held blowtorch.
The flame heater that the hand-held blowtorch uses as a kind of operation field, it is widely used in motor manufacturing, non-ferrous metal welding, paint removal, the oven dry of casting sand mo(u)ld, and the hot-water heating maintenance is in the execute-in-place of operations such as house decoraton, vehicle maintenance.The hand-held blowtorch of existing various types all adopts gasoline as fuel, the fitting structure complexity, weight is big, the cost height, heating need utilize external heating mode that firn-jet head is carried out preheating when using, and wants frequent gas injection pressurization in the use, so it uses troublesome poeration, dangerous, long-time use easily makes people's fatigue, is unfavorable for the assurance of operation quality.
The purpose of this utility model provides a kind of simple in structure, and cost is low, and is in light weight, is beneficial to hand-held the use, and firn-jet head need not preheating during use, need not the oil liquefied gas cassette blowtorch of gas injection pressurization in the use.
Oil liquefied gas cassette blowtorch is by having the connection chuck and the gas receiver of compression spring air valve, the coupling that has chuck, jet metering pin valve, appendix, firn-jet head constitutes, coupling is screwed to fix by chuck and is fixedlyed connected with gas receiver, and the coupling air passing hole seals by having the whole elastic seal cap that is connected annular shoulder with gas receiver escape pipe interface.Jet metering pin valve air inlet end is connected with coupling, and its interface is by the annular shoulder sealing of sealing cap.Jet metering pin valve gas outlet end is a taper type, appendix air inlet end is the gradually expanded form that adapts to jet metering pin valve gas outlet end shape, appendix air inlet end connects back appendix air inlet end wall surface and compresses and be attached on the end wall surface of jet metering pin valve gas outlet appendix, jet metering pin valve sealing joint by being set on trim ring on the appendix with jet metering pin valve gas outlet end, appendix gas outlet end is installed with the trunnion with capillary venthole, and firn-jet head and appendix gas outlet end are tightly connected.
In order to prevent that combustion gas from leaking, the assurance blowtorch is safe and reliable, further improving of oil liquefied gas cassette blowtorch is, jet metering pin valve with the whole spool tappet that is connected of needle-like spool on annular groove is arranged, card crouches in the annular groove the cyclic spring sealing ring, and cyclic spring seal ring with outer end face holds out against to contact with the spool chamber wall spool chamber is hedged off from the outer world.
The oil liquefied gas cassette blowtorch that the utility model provides, simple in structure, in light weight, gas receiver also is the blowtorch lever, and is easy to use.Fuel is cheap, and cost of use is low.Light fixture sealing position is few, and the hermetically-sealed construction sealing is reliable, thereby the light fixture safety in utilization is good.
Accompanying drawing is an embodiment of the present utility model, further specifies the utility model below in conjunction with embodiment.
Fig. 1 is the outside drawing of oil liquefied gas cassette blowtorch.
Fig. 2 is oil liquefied gas cassette Blowtorch structure figure.
As shown in Figure 1, oil liquefied gas cassette blowtorch is by having the gas receiver A that connects chuck and compression spring air valve, having the coupling B, jet metering pin valve C, appendix D, the firn-jet head E that are connected chuck and constitute.
Oil liquefied gas cassette Blowtorch structure as shown in Figure 2, the coupling that constitutes by joint (3), by screw (19) chuck fixedly connected with joint (2) spirals to twist to fix by chuck and Connection Card on the gas receiver (1) and connects, and coupling air passing hole and gas receiver escape pipe interface seal by having the elastic seal cap (4) that integral body is connected annular shoulder.For preventing sealing cap air passing hole distortion obstruction, stud with riveting pipe (5) in the sealing cap air passing hole.Jet metering pin valve air inlet end is fixedly connected by screw (18) and coupling, and its interface is by the sealing of elastic seal cap annular shoulder.Jet metering pin valve is by three way type valve body (6), needle-like spool (7), the spool tappet (16) that is connected with spool integral body, knob (17), spool tappet back-up ring (15) formation, the spool tappet has been located annular groove after being positioned at spool, card crouches in the annular groove cyclic spring sealing ring (8), and the seal ring with outer end face holds out against to contact with the spool chamber wall spool chamber is hedged off from the outer world.Jet metering pin valve gas outlet end is a taper type, appendix air inlet end is the gradually expanded form that adapts to jet metering pin valve gas outlet end shape, appendix air inlet end is fixedlyed connected with jet metering pin valve air inlet end by locknut (10), and appendix air inlet end wall surface compresses and is attached on the jet metering pin valve air inlet end wall surface sealing joint by being set on trim ring (9) on the appendix.Appendix gas outlet end studs with the trunnion (14) with capillary venthole, and the firn-jet head that is made of air nozzle (13), spit tube (12) is sealedly and fixedly connected at appendix gas outlet end.
