Description
The utility model relates to a kind of oxygen-acetylene welding welding torch.
Oxygen-acetylene welding is a kind of manufacturing process that generally uses in metal processing and the device fabrication, the employed main tool of gas welding is a welding torch, and the acetylene vent cap axis that is communicated with nozzle acetylene inlet plenum behind the acetylene adjusting control valve spool chamber axis of existing welding torch and the valve is a broken line thereby the moulding of can't once holing.The oxygen air inlet tube socket axis of welding torch is general big to vertical with oxygen air inlet vent cap axis, thereby the moulding of also can't once holing of oxygen air inlet tube socket and oxygen air inlet vent cap, so all the back machine-shaping of holing respectively of acetylene vent cap and oxygen air inlet tube socket behind acetylene adjusting control valve spool chamber, the valve, oxygen air inlet vent cap when welding torch is made.Two apertures that acetylene vent cap behind the valve, the boring of oxygen air inlet vent cap are produced are usually said fabrication hole, two fabrication holes after welding torch is made again with its shutoff.Because the existence of fabrication hole has not only destroyed the overall structure of welding torch, and very easily the generation leakage has brought totally unfavorable influence for the use of welding torch, and particularly safety in utilization descends greatly.Secondly, the structure of existing welding torch also causes the welding torch body thickness big, and material usage is many, and weight is big, disadvantages such as cost of manufacture height.
The purpose of this utility model is improved existing oxygen-acetylene welding welding torch, provides a kind of overall structure, sealing strong, the welding torch body thickness, and volume is little, and is in light weight, the no fabrication hole jetting-sucking welding torch that cost of manufacture is low.
The purpose of this utility model realizes by following manner.
By the spool chamber (21) of welding torch main body (6), boring back machine-shaping on main body, be loaded on acetylene control valve that the spool (22) that has tappet (23) and handwheel (1) spool chamber in constitutes, on main body boring back machine-shaping have adapter socket (4) and with valve that spool chamber is communicated with before acetylene vent cap (3).
The machine-shaping of boring back on main body with nozzle acetylene inlet plenum (16), acetylene vent cap (19) behind the valve that spool chamber is communicated with, the nozzle mixing chamber (17) of boring back machine-shaping on main body, acetylene inlet plenum (16), oxygen control valve spool chamber (13), be loaded on the nozzle (15) of oxygen control valve outlet side, by spool chamber, be loaded on the oxygen control valve that the needle-like spool (14) that has spool tappet (12) and handwheel (11) in the spool chamber constitutes, acetylene vent cap axis is located along the same line behind the acetylene control valve spool chamber axis of the welding torch that has oxygen air inlet vent cap (18) formation of taking over socket (20) that is communicated with the oxygen control valve spool chamber and the valve, have the oxygen air inlet vent cap of taking over interface and be one and accompany the inclination duct of certain angle with oxygen control valve spool chamber axis, acetylene control valve spool chamber, machine-shaping after the acetylene vent cap is once holed behind the valve, oxygen air inlet vent cap, machine-shaping after oxygen air inlet vent cap adapter socket is once holed.
In order to reduce the main body physical dimension, reduce material usage, between the oxygen air inlet vent cap of welding torch and adapter socket transition air chamber (8) is arranged, blocked to prevent air inlet pipe (7) grafting back air flue.
For the another kind of structural shape that reduces how much overall dimensions of material of main part consumption and main body is that oxygen insertion pipe insertion end and corresponding tube wall place, oxygen air inlet vent cap aperture are shaped on passage or breach, make the oxygen ventilation duct be connected unimpeded with adapter.
The acetylene vent cap is located on the same line behind no fabrication hole jetting-sucking welding torch acetylene control valve spool chamber axis and the valve, thereby the moulding and reduced the thickness of main body of can once holing.Oxygen air inlet vent cap is one to accompany certain angle inclination duct with oxygen control valve spool chamber axis, the machine-shaping of once holing, thus eliminated the fabrication hole of existing welding torch, improved the overall structure and the sealing of stove torch, improved safe and reliable.How much overall dimensions of welding torch are little, and material usage is few, thereby has reduced manufacturing cost.Welding torch is in light weight, is convenient to handgrip and uses.
Accompanying drawing is an embodiment of the present utility model, further specifies the utility model below in conjunction with embodiment.
Fig. 1 is no fabrication hole jetting-sucking welding torch structure chart.
No fabrication hole jetting-sucking welding torch is by main body (6), the spool chamber (21) of boring and moulding on main body, be loaded on spool (22) seal (24) that has tappet (23) and operation handwheel (1) in the valve pocket, the acetylene control valve that union (screwed)bonnet (UB (2) constitutes, acetylene vent cap (3) before the valve that has adapter socket (4) that is communicated with spool chamber of boring and moulding on main body, be fixedly connected on the acetylene air inlet pipe (5) on the socket, on main body boring and moulding with nozzle acetylene inlet plenum (16), acetylene vent cap (19) behind the valve that acetylene control valve spool chamber is communicated with, the spool chamber (13) of boring and moulding on main body, be loaded on the needle-like spool (14) that has tappet (12) and operation handwheel (11) in the spool chamber, seal (10), the oxygen control valve that screw-type gland (9) constitutes, be loaded on the nozzle (15) of oxygen control valve end, with the oxygen control valve spool chamber once hole the back machine-shaping nozzle mixing chamber (17), the acetylene inlet plenum, be communicated with and have the oxygen air inlet vent cap (18) of taking over socket (20) with the oxygen control valve spool chamber, being fixedly connected on the oxygen intake pipe (2) of taking over socket constitutes, acetylene control valve valve core axis and spool acetylene vent cap axis are located on the same line, oxygen air inlet vent cap is one to accompany the inclination duct of certain angle with oxygen control valve spool chamber axis, oxygen air inlet vent cap, machine-shaping after the adapter socket is once holed.Oxygen is taken between socket and oxygen air inlet vent cap transition air chamber (8), and oxygen is entered by the transition air chamber by air inlet pipe and enters oxygen air inlet vent cap.
Except that schematic structure, in the time of also can patching oxygen intake pipe tube wall insertion end and corresponding section, oxygen air inlet vent cap aperture the excision of pipe or boring made between oxygen air inlet vent cap and air inlet pipe ventilation unimpeded.
