The diameter difference that the two is formed just is convenient for carrying out the two stronger welding, after the completion of solder joint two welds, is equivalent to this
Diameter difference carry out arc-shaped transition, make the hydraulic oil in hydraulic tube, from flange arc-shaped transition to steel pipe in, effectively prevent hydraulic oil
Solder joint one is impacted by the gap of steel pipe and flange between the two, another scheme is that bottom diameter is made to be equal to pipe diameter, is led to
It crosses and sets chamfering two, the welding that the effect of chamfering two is convenient for solder joint two close to stepped hole side in bottom outlet, two schemes all may be used
Gap between flange and steel pipe is sealed, service life is increased.

Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Embodiment one:
Referring to Fig. 1, a kind of hydraulic tube flange arrangement, including steel pipe 2 and the flange 1 being welded on 2 one end of steel pipe, in conjunction with figure
2,1 end face of flange is square, and 1 end face center of flange vertically offers the logical oily bottom outlet 3 through flange 1,1 one end of flange
The stepped hole 4 that a diameter is greater than bottom outlet 3 is offered on face and the same center line of bottom outlet 3,4 depth of stepped hole is about that flange 1 is thick
The half of degree, the diameter of stepped hole 4 is bigger by 0.5 than 2 outer diameter of steel pipe to arrive 2mm, is located at 4 one end face Yan Tai of stepped hole on flange 1
Rank hole 4 is machined with a circle chamfering 1,4 diameter of stepped hole in flange 1 be greater than 3 diameter of bottom outlet be formed between the two one with
The parallel step surface 10 in 1 end face of flange, 2 internal diameter of steel pipe is equal with 3 diameter of bottom outlet, and 2 one end of steel pipe gos deep into stepped hole 4 and steel pipe
2 end faces are abutted with step surface 10, and flange 1 is far from the closure gasket groove 9 for offering annular on 4 one end face of stepped hole, in closure gasket groove 9
Diameter is slightly larger than 3 diameter of bottom outlet, can be used for placing sealing ring in closure gasket groove 9, can increase leakproofness, in the present embodiment, steel pipe 2
It is two-sided welding with flange 1, is equipped with a lap welding point 1 in chamfering 1, solder joint 1 is by the lateral surface of steel pipe 2 and 1 end face of flange
Welding, 2 one end of steel pipe and bottom outlet 3 in flange 1 are equipped with a lap welding point 26, weld for the ease of solder joint 26 and for method
Orchid 1 is stronger with the welding of steel pipe 2, increases 3 diameter of bottom outlet of flange 1, keeps the diameter of bottom outlet 3 3mm smaller than 2 outer diameter of steel pipe,
Remaining size constancy, solder joint 26 are welded in bottom outlet 3 and 2 internal diameter of steel pipe and are formed in diameter difference, what solder joint 1 and solder joint 26 were formed
Two-sided welding avoids the hydraulic oil in hydraulic tube flange arrangement and enters in the gap between 2 outer diameter of stepped hole 4 and steel pipe, prevents
Only hydraulic oil butt welding point 1 generates impact, can greatly reduce risk of leakage, improve reliability, extend hydraulic pipe flange
Service life.
Embodiment two:
Referring to Fig. 3, embodiment two and embodiment one the difference is that, when bottom outlet 3 and other component need to cooperate, Bu Nenggai
When becoming 3 diameter of bottom outlet, need to process a circle chamfering 28 on step surface 10,3 diameter of bottom outlet is equal to 2 internal diameter of steel pipe, this reality at this time
The solder joint 26 applied in example is located in chamfering 28, and 2 end face of steel pipe and bottom outlet 3 are welded by solder joint 26 in chamfering 28, realized
Two-sided welding, in the case where that can not reduce 3 diameter of bottom outlet, the hydraulic oil equally avoided in hydraulic tube flange arrangement enters
In gap between 2 outer diameter of stepped hole 4 and steel pipe, it is therefore prevented that hydraulic oil butt welding point 1 generates impact, can greatly reduce infiltration
It leaks out danger, improves reliability, extend the service life of hydraulic pipe flange.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
