The problem of oxidation.
The utility model solve above technical problem technical scheme be：A kind of stainless steel tube elbow protective atmosphere heat is provided
Gas operated device, including casing, deflector and gather qi together hole are handled, the casing constitutes bend pipe rest area and protection by dividing plate segmentation
Gas air inlet area, the protection gas air inlet area is located at the underface of the bend pipe rest area, the protection gas air inlet area side lower
Provided with protection gas air admission hole, the protection gas air inlet for separating the round baffling of composition by deflector in the protection gas air inlet area is led to
Road, protect gas inlet channel lower end with it is described protect gas air admission hole communicate, the bend pipe rest area by be evenly distributed on every
Gather qi together hole on plate is communicated with the protection gas air inlet area；Provided with the opening for placing pipe bend at the top of the body side, pass through
The opening is communicated with the cavity of the bend pipe rest area.
Further restriction technical scheme of the present utility model, foregoing stainless steel tube elbow protective atmosphere heat treatment air guide dress
Put, the cavity inner support face of the bend pipe rest area is provided with the support porcelain tube of many parallel arrangements, the cloth of the support porcelain tube
Put direction and steel elbow to enter outgoing direction vertical, supported by using porcelain tube, ensure that thermal deformation does not occur for supporting surface, protected
The stabilization of supporting surface is demonstrate,proved, the finished product error of steel elbow is reduced.
Install and survey in foregoing stainless steel tube elbow protective atmosphere heat treatment gas operated device, the cavity of the bend pipe rest area
Temperature in temperature probe, real-time monitoring case body, it is ensured that the heat treatment of steel pipe is carried out under fully controllable environment.
Foregoing stainless steel tube elbow protective atmosphere heat treatment gas operated device, the protection gas air admission hole is put with the casing
The opening for putting pipe bend is arranged on homonymy.
Further, foregoing stainless steel tube elbow protective atmosphere heat treatment gas operated device, the protection gas air admission hole by
It is multiple to be constituted along the stomata that body side width is arranged side by side, it is ensured that protective gas enters can be uniformly distributed in casing,
Effectively drain the air in casing, it is ensured that the purity of protective atmosphere.
The beneficial effects of the utility model are：The utility model highly versatile, simple in construction, practical, low cost, operation letter
Just, it is safe, by setting deflector in casing, gas air inlet area will be protected to separate the protection gas air inlet that composition comes and goes baffling
Passage, while gather qi together hole is uniformly arranged on dividing plate, so in heat treatment process, it is possible to solve air can not emptying ask
Topic, improves the purity of protective atmosphere, can solve the problem of electrical heating elbow heat treatment inner and outer surfaces oxidation, effectively improve steel
Pipe decay resistance, by the steel elbow quality of this equipment making apparently higher than like product.

Embodiment
Embodiment 1
The present embodiment is a kind of stainless steel tube elbow protective atmosphere heat treatment gas operated device, structure as Figure 1-3, including
Casing, deflector and gather qi together hole, casing constitute bend pipe rest area 1 and protection gas air inlet area 2 by the segmentation of dividing plate 4, and bend pipe is placed
Temperature probe 3 is installed, protection gas air inlet area is located under the underface of bend pipe rest area, protection gas air inlet area side in the cavity in area
Portion is made up of provided with protection gas air admission hole 5, protection gas air admission hole multiple stomatas being arranged side by side along body side width.
Protect by deflector 6 to separate in gas air inlet area and constitute the protection gas inlet channel for coming and going baffling, under protection gas inlet channel
End is communicated with protection gas air admission hole, and bend pipe rest area passes through the gather qi together hole 9 being evenly distributed on dividing plate and protection gas air inlet area phase
It is logical；Provided with the opening 7 for placing pipe bend at the top of body side, the opening that protection gas air admission hole places pipe bend with casing is arranged on
Homonymy, is communicated by the opening 7 for placing pipe bend with the cavity of bend pipe rest area, is set on the cavity inner support face of bend pipe rest area
Have the support porcelain tubes 8 of many parallel arrangements, support porcelain tube arranged direction and steel elbow to enter outgoing direction vertical.
The present embodiment when in use, accesses argon gas, argon gas is by protection gas air admission hole in the protection gas air admission hole of body side
Into protection gas air inlet area, argon gas drives air out of in the protection gas inlet channel for coming and going baffling, when argon gas reaches dividing plate
Gather qi together hole enters bend pipe rest area, and now argon gas is full of the cavity of whole bend pipe rest area, the placing steel tubes in bend pipe rest area
Elbow 10 carries out heat treatment operation, ensure that the purity of protective atmosphere, so as to effectively protect pipe outer surface, and then improves steel
The decay resistance of pipe.
In addition to the implementation, the utility model can also have other embodiment.All use equivalents or equivalent change
The technical scheme to be formed is changed, the protection domain of the utility model requirement is all fallen within.
