The technical scheme that the utility model proposes is: the electricity-saving lamp fuel gas welding torch, comprise the rifle body, be installed in inlet end on the rifle body, be installed on the rifle body as the Y shape air jet pipe of outlet side and inlet end to the gas channel between the Y shape air jet pipe, it is characterized in that the valve pocket that is shaped on single-revolution shape on the described rifle body, this valve pocket series connection inserts gas channel; Inner conical is made at inwall position in the middle of the valve pocket, inserts a spool slidably in the valve pocket, and the bottom of spool is shaped on and the matched cone of described inner conical, to form closable valve port; The bottom of spool also is subjected to the effect of a spring, makes spool have the potential energy of the close port of moving upward; Other has one handle to be positioned at the top of spool swingably, it is moved downward open valve port so that drive spool when being subjected to manual pushing tow; Also be shaped on a current by pass on the spool, this current by pass begins from the spool bottom along the outer circumference surface that extended to the spool middle part after cone passed through in valve core axis, still to connect described gas channel when valve port is closed; Described inlet end is shaped on two air inlets, and one of them air inlet is communicated with described valve pocket, and another air inlet is communicated with described Y shape air jet pipe by a branch road.

Described handle is hinged on the rifle body.

Use principle of the present utility model is: with the rubber appendix two air inlet 1-11 of inlet end and 1-12 are joined with first end and second end of three-way control valve respectively earlier, then in the 3rd end feeding combustion gas of three-way control valve and light.Operating personnel still earlier rotate first end of three-way control valve and the valve knob of second end respectively, regulate after the gas flow among two air inlet 1-11 and the 1-12, (flow are opened to maximum with light finger pushing handle 11; This moment, air-flow mainly sprayed by Y shape air jet pipe through valve pocket 15, valve port, outlet 8-1, gas channel 8 successively from inlet end 1 again), again welding gun is aimed at the power saving fluorescent lamps heating, cooperate with air-extractor vacuumize, gas injection and seal, binding or welding work; After finishing, heating only needs release lever, spring promotes to move close port on the spool, and gas channel promptly is cut off, and only has a little air-flow to enter Y shape air jet pipe from air inlet 1-11, outlet 2, branch road 7 and gas channel respectively, thereby big fire becomes small kindling material, a circulation end immediately; When needing to heat second power saving fluorescent lamps by the time, only need with the light finger pushing handle air-flow be increased again, kindling material just increases immediately, can burn with the throughput of setting up once more and power saving fluorescent lamps be heated.

The beneficial effects of the utility model are: the welding gun that is provided still keeps a burning fire kind owing to do not cut off air-flow fully when cutting out spool; Operating personnel can enable very hot oven as required respectively and keep two kinds of operating modes of kindling material during use, when not only having satisfied sintering to the needs of big flame, and the flame of loitering phase reduced to minimum, thus having reduced energy consumption significantly, fuel saving reaches more than 50%; In addition and since once more when lighting big flame only with hand refer to the pushing tow handle, need not regulate the flow proportional of liquefied gas and oxygen again, so operate also very convenient; Thereby has a broad prospect for its application.
