Abstract
The utility model relates to a welding and cutting gun, which comprises a nozzle, wherein an injection and suction pipe is sleeved on the outside of the nozzle; the front end of the injection and suction pipe is connected with a mixing pipe; a welding nozzle is installed on the mixing pipe; a mixing chamber is arranged on a gun body; the nozzle and the injection and suction pipe are arranged inside the mixing chamber; a connecting pipe is sleeved on the outsides of the injection and suction pipe and the mixing pipe; the upper end and the lower end on the outside of the mixing chamber are respectively provided with a cutting nozzle joint; a valve body is arranged on the lower part inside the gun body. The utility model has the advantages of compact structure, small size, convenience for carrying, possibility of being used for cutting and welding, flexible installation positions of the cutting nozzle, possibility of being assembled and disassembled at any time, high combustion rate, capability of generating effective flame under low atmospheric pressure, capability of saving gas by 40% to 50%, and energy saving.
Description
Technical field
The utility model relates to a kind of welding cut bit, particularly a kind of pistol type solder cutting gun.
Background technology
The welding gun volume that uses is big at present, is not with cutting torch or cutting torch not removable, can not finish weldering on same instrument, cut work, uses inconvenience, is a passage because injecting tube and nozzle directly are communicated with, and combustion rate is not high, expends the energy.
The utility model content
The purpose of this utility model provides that a kind of volume is little, cutting torch dismounting at any time, easy to use, cut weldering and use same a kind of solder cutting gun that instrument is finished.
The purpose of this utility model is achieved through the following technical solutions:
A kind of solder cutting gun, comprise nozzle, outer socket one injecting tube of nozzle, the injecting tube front end connects a mixing tube, and tip is housed on the mixing tube, and rifle body internal upper part is established a mixing chamber, said nozzle, injecting tube are located in the mixing chamber, outer socket one tube connector of injecting tube and mixing tube, a cutting head joint is respectively established in two ends up and down in the mixing chamber outside, and valve body is established in the bottom in the rifle body.
Flexibly connect a cutting oxygen communicating pipe on above-mentioned arbitrary cutting head joint, cutting oxygen communicating pipe front end is adorned a cutting torch.
Be provided with cutting oxygen control valve, acetylene control valve and oxygen control valve in the described valve body, above-mentioned cutting oxygen control valve was communicated with oxygen communicating pipe with cutting by communicating pipe, above-mentioned acetylene control valve was communicated with injecting tube by communicating pipe, and above-mentioned oxygen control valve was communicated with nozzle by communicating pipe.
The utility model compact conformation, volume is little, and is easy to carry, and welding all can use, and the cutting torch installation site is flexible, at any time dismounting; The combustion rate height, Weldability is improved, and makes noble metal soldered easily, reduces the solder flux consumption simultaneously, owing to just can produce effective flame under low pressure, can economize gas 40%～50%, energy savings.

The specific embodiment
A kind of solder cutting gun, nozzle 2, injecting tube 3 are fixed in the mixing chamber 1, and nozzle 2 is socketed in the injecting tube 3, and injecting tube 3 has passage 21, and injecting tube 3 and mixing tube 5 thread bush are connected in the tube connector 4.
Be located at when using welding on the oxygen connection 11 of valve body 13 lower ends and the acetylene joint 10 and connect oxygen hose and acetylene hose respectively, open oxygen control valve 12, oxygen enters nozzle 2 by communicating pipe 18, and penetrates fast from nozzle 2, form vacuum in nozzle periphery, promptly produce negative pressure and suction.At this moment open acetylene control valve 9 again, acetylene accumulates in around the nozzle 2 through entering gap 20 between injecting tube 3 and the nozzle 2 communicating pipe 17.Because the suction function of oxygen jet, acetylene is very fast to be sucked injecting tube 3 by oxygen, enters mixing tube 5, mixes the back by a certain percentage from tip 6 ejections in mixing tube 5, and igniting is regulated oxygen control valve 12 and acetylene control valve 9 to obtaining optimum state flame.
On cutting head joint 19, connect tube connector 14 during cutting, light the oxygen-acetylene gas of tip 6 ejections, allow oxygen-acetylene torch heating of metal, open cutting oxygen control valve 8, through entering tube connector 14 communicating pipe 16 and, can cutting from the cutting torch ejection to aglow.
