Abstract

The utility model relates to a Handle Self-heating welding and cutting torch which is an improvement of welding and cutting torch, and the utility model is composed of a gun body, a cutting oxygen pipe, a cutting oxygen valve, a handle, an oxygen inlet pipe, an oil needle valve, an oil inlet pipe, an oil pipe, a cutting nozzle, etc. The utility model is characterized in that the cutting nozzle is connected with one end of the head part of the gun body, the other end is connected with the cutting oxygen pipe and the oil pipe, the middle part of the gun body is provided with a cutting oxygen valve, the lower part is provided with the handle, and the bottom of the gun body is provided with the oil needle valve. The utility model can be used for welding and cutting non-ferrous metal and ferrous metal, closing calcination of quartz glass productions and various flame workings, and more than 90% fuel cost can be reduced compared with oxygen-acetylene gas fuel.

Description

Handle type self-heating welding torch

The utility model is the improvement of butt welding cutting torch equipment, is a kind of handle type self-heating welding torch.

At present, existing welding and cutting device adopts electric welding, gas welding etc. usually, conventional oxygen---the acetylene gas that adopts of gas welding, and oxygen---natural gas is a fuel, has the cost height, transports difficult, deficiencies such as keeping is difficult, not portable, poor stability, and the cost height of fuel.

The purpose of this utility model be for coloured, ferrous metal weldering, cutting seal calcining and the processing of various flame of processing and quartz glass product, a kind of liquid oils and combustion-supporting oxygen of adopting is provided is the handle type self-heating welding torch of fuel.

The utility model handle type self-heating welding torch content Description:

The utility model handle type self-heating welding torch, be by the rifle body, the cutting oxygen pipe, cutting oxygen valve, handle, advance oxygen hose, oil needle valve, oil inlet pipe, oil pipe, formations such as cutting torch, it is characterized in that: cutting torch is the conulite of being made by red copper, built-in mouth core, the internal thread of the external screw thread of one end and rifle body head is fastenedly connected, the other end of rifle body head connects cutting oxygen pipe and oil pipe, the middle part of rifle body is provided with a cutting oxygen valve, its underpart is a handle, the bottom of rifle body is an oil needle valve, one air inlet pipe is arranged on oil needle valve, an oil inlet pipe is arranged below the oil needle valve.

The utility model handle type self-heating welding torch can be used for welding coloured, ferrous metal, and sealing of quartz glass product calcined and the processing of various flame, with oxygen---and the contrast of acetylene gas fuel can reduce fuel cost more than 90%; Its performance is safe and reliable, uses simply, and is easy to carry, in light weight, is specially adapted to particular surroundings operations such as field, high-altitude.

Embodiment:

Fig. 1 is a handle type self-heating welding torch structural representation

See Fig. 1, the utility model is by rifle body 1, cutting oxygen pipe 2, cutting oxygen valve 3, handle 4, advances oxygen hose 5, oil needle valve 6, oil inlet pipe 7, oil pipe 8, cutting torch 9, vaporizer 10 and constitute.Cutting torch 9 is conulites of being made by red copper, built-in mouth core, and an end has external screw thread, is fastenedly connected with the internal thread of rifle body 1 head one end, be the passage that is used for logical hyperbaric oxygen, oxygen and liquid oil gas fully are mixed into mist in vaporizer 10; Cutting oxygen pipe 2 welds together with the other end of oil pipe 8 with rifle body head, makes it can excellent sealing, is respectively the passage of high pressure oxygen and fluid oil in cutting process; At the middle part of rifle body 1 cutting oxygen valve 3 is set, is used for regulating the throughput of cutting oxygen, its underpart is a handle 4, is the portion of the handle of welding torch; The oil needle valve 6 of the bottom of rifle body 1 is the size that is used to regulate oil mass, to reach best cutting effect; Being oxygen hose 5 on oil needle valve 6, is oil inlet pipe 7 below the oil needle valve 6.

Add 0.5-0.8 kilogram pressure to oil tank during the welding operation, make the interior oil of oil tank send into the end of handle type self-heating welding torch along petroleum pipeline.
