Description
Technical field
The utility model relates to a kind of welding gun, particularly relates to a kind of water cooled welding torch being applied to gate valve welding, belongs to the technical field of gate valve welding gun equipment.
Background technology
Gate valve generally needs to carry out the operations such as interior welds, and the welding temperature of gate valve inner chamber is high, and welding gun in high temperature environments its cyclic duration factor is low, causes the nozzle ignition tip life-span short.
And water cooled welding torch of the prior art, water-cooled DeGrain, and water-cooled scope is less, insulating barrier between ignition tip and rifle head body causes cooling effect lower, easy appearance on ignition tip is splashed, and causes wire feed freely easily not cause weld defect, affects welding quality.
Utility model content
The purpose of this utility model is to solve above-mentioned technical problem, proposes the water cooled welding torch being applied to gate valve welding.
The purpose of this utility model, will be achieved by the following technical programs:
Be applied to the water cooled welding torch of gate valve welding, comprise air inlet pipe and arc welding gun head, especially, described water cooled welding torch comprises a cooling water pipe and a water-cooled body, the sheathed coated described air inlet pipe of described water-cooled body and cooling water pipe, the outer wall of described water-cooled body has a water-cooling jacket;
Described arc welding gun head comprises cooling gun head and is arranged at nozzle and the ignition tip of cooling gun cephalic par, described ignition tip is positioned at nozzle, be provided with the cooling cycle chamber be connected with cooling water pipe in described cooling gun head, there is between described nozzle and ignition tip the gas be positioned at bottom ignition tip and sieve.
Preferably, the outer surface of described nozzle has nanometer insulating coating.
Preferably, described air inlet pipe is gooseneck.
Preferably, the outer surface of described air inlet pipe has nanometer insulating coating.
Preferably, described nozzle is chromium pick copper nozzle, and described ignition tip is chromium pick copper ignition tip.
Preferably, described gas sieve is the gas sieve of three layers, 100 order.
The beneficial effects of the utility model are mainly reflected in:
1. be provided with cooling cycle chamber in cooling gun head, cooling water pipe directly carries out cooling water supply to cooling cycle chamber, and cooling effect is remarkable;
2. air inlet pipe and cooling water pipe are coated with water-cooled body, and water-cooled body all has cooling effect to air inlet pipe and cooling water pipe;
3. nozzle outer surface has nanometer insulating coating, and nanometer insulating coating replaces traditional internal insulating layer, makes heat transfer effect between cooling gun head and nozzle more excellent, meanwhile, has certain isolation effect to the high temperature of gate valve inner chamber;
4. add gas sieve, increase the deflection of gas and the uniformity of air-flow, reduce resultant turbulence.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model is applied to the water cooled welding torch of gate valve welding.
Detailed description of the invention
The utility model provides the water cooled welding torch being applied to gate valve welding, have cooling effect significantly, increase the deflection of gas and air-flow uniformity, reduce the features such as resultant turbulence.
As shown in Figure 1, be applied to the water cooled welding torch of gate valve welding, comprise air inlet pipe 1 and arc welding gun head 2, water cooled welding torch comprises cooling water pipe 3 and a water-cooled body 4, the sheathed coated air inlet pipe 1 of water-cooled body 4 and cooling water pipe 3, and air inlet pipe 1 is gooseneck, water cooled welding torch is facilitated to probe into brake valve body inside, the outer wall of water-cooled body 4 has a water-cooling jacket 5, and water-cooling jacket 5 pairs of water-cooled bodys 4 cool, and water-cooled body 4 pairs of air inlet pipe 1 and cooling water pipe 3 carry out heat exchange cooling; Arc welding gun head 2 comprises cooling gun head 21 and is arranged at nozzle 22 and the ignition tip 23 of cooling gun head 21 end, nozzle 22 is chromium pick copper nozzle, ignition tip 23 is chromium pick copper ignition tip, ignition tip 23 is positioned at nozzle 22, be provided with the cooling cycle chamber 6 be connected with cooling water pipe 3 in cooling gun head 21, there is between nozzle 22 and ignition tip 23 gas be positioned at bottom ignition tip 23 and sieve 7.
For increasing the water-cooled effect of water cooled welding torch, insulating coating in traditional is removed, and coat nanometer insulating coating at the outer surface of nozzle 22 and the outer surface of air inlet pipe 1, interior insulating coating is poor to the heat insulation cooling effect that causes between nozzle and water-cooling welding torch head, and eliminate interior insulating coating and make the heat exchange between nozzle and water-cooling welding torch head more smooth and easy, cooling effect is obvious, the nanometer insulating coating of outer surface makes again nozzle and air inlet pipe have the effect heat insulation with external high temperature, adds the cooling effect of water cooled welding torch.
Further refinement this programme, gas sieve 7 is the gas sieve of three layers, 100 order, increases the deflection of gas and the uniformity of air-flow, reduces resultant turbulence.
Below the water-cooled principle of water cooled welding torch of the present utility model:
Cooling water pipe and water-cooling jacket carry out cool cycles simultaneously, the cooling cycle chamber of cold medium circulation in cooling gun head in cooling water pipe, cooling gun head is lowered the temperature, simultaneously, cooling gun head carries out heat exchange cooling to nozzle and ignition tip, and water-cooling jacket is lowered the temperature to water-cooled body, water-cooled body carries out heat exchange cooling to air inlet pipe and cooling water pipe, make gas temperature in air inlet pipe lower, cooling water pipe internal circulation heat-exchanging cold medium is out lowered the temperature simultaneously, ensured the cooling effect of water cooled welding torch.
The utility model still has numerous embodiments, all employing equivalents or equivalent transformation and all technical schemes formed, and all drops within protection domain of the present utility model.
