Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
As shown in Figure 1, a kind of nickel-based alloy pipe, including hollow tube body 1, the tube body 1 includes at least internal layer 2, mistake
Layer 3 and protective layer 4 are crossed, and internal layer 2, transition zone 3 and protective layer 4 are set gradually from the inside to the outside, the internal layer 2 is by nichrome
It is made, the transition zone 3 is made of carbon steel material, and the protective layer 4 is made of ambrose alloy powder spray.Nichrome can resist
The corrosion of the gases such as high-temperature oxydation and sulfur-bearing, vanadium, corrosion resistance enhance with the increase of chromium content, and this kind of alloy also has preferably
Resistance to hydroxide (such as NaOH, KOH) corrosion and anticorrosion stress-resistant ability, and monel has a wearability and oxygen simultaneously
The property changed is strengthened by the hardness that the methods of plasma arc spraying coating or flame spray coating carry out surface covering, and transition zone 3 is made
Based on material rise integral frame supporting role.
1 end of tube body is equipped with terminal pad 5, and terminal pad 5 is circular step structure, and the terminal pad 5 has
There are top plate portion 6 and chassis portion 7, the diameter in the chassis portion 7 is greater than the diameter in top plate portion 6, and the top plate portion 6 is embedded in tube body
1, and by being welded and fixed between terminal pad 5 and tube body 1.Terminal pad 5 is embedded in tube body 1, i.e. top plate portion 6 is inserted into tube body 1, terminal pad
5 and the original seam crossing in 1 outer surface of tube body by being welded and fixed, improve leakproofness and bonding strength.5 structure of terminal pad is similar to more
Layer cake shape is not made excessively to illustrate and limit herein.
7 end face of chassis portion is equipped with connecting hole 8 and mounting groove 9, and 8 diameter of connecting hole is from chassis portion 7 to top
6 direction of pan portion becomes larger.When two tube bodies 1 are docked by two terminal pads 5, liquid or gas when passing through terminal pad 5, by
Diameter first becomes smaller the influence to become larger afterwards, and radial flow speed can first become larger, and liquid or gas are quickly through terminal pad 5, then radial flow
Speed becomes larger again, and liquid or gas restore initial motion state.Weaken radial forces with this, while constant in external input power
In the case where, it will increase the power axially flowed, avoid being mutually disengaged between terminal pad 5.
The top plate portion 6 is equipped with discharge orifice 10, and discharge orifice 10 is connected with connecting hole 8, and the mounting groove 9 is ring junction
Structure, and sealing ring 11 is equipped in mounting groove 9.It is sealed by sealing ring 11, prevents radial exudation.
The lateral wall of described smaller one end of 5 diameter of terminal pad is equipped with external screw thread, and 1 inner tubal wall of tube body is equipped with
