The expanding sub-assembly of joint hydraulic pressure includes screw rod, left pad, right pad, left sealing ring, right sealing ring, left end cap, right end cap, shape
Pipe joint of memory alloy and nut；It is characterized in that：Left pad, left sealing ring, left end cap, shape are installed successively on the screw rod
Shape memory alloys pipe joint, right end cap, right sealing ring, right pad, then fasten marmem pipe joint liquid with nut
Companding footpath sub-assembly；The marmem pipe joint is provided with interior muscle, and high-pressure liquid medium inlet is arranged on screw rod
Top, high-pressure liquid medium is injected into inside the marmem pipe joint with interior muscle by high-pressure liquid medium inlet；
The expanding sub-assembly of marmem pipe joint hydraulic pressure for installing good seal is placed in thick-walled pipe.
The present invention enters to above-mentioned screw rod in order that realize that high-pressure liquid medium is expanding with interior muscle marmem pipe joint
Row is further set：Inside screw is provided with 90 ° of through holes of corner, is noted by high-pressure liquid medium entrance for high-pressure liquid medium
Enter to inside marmem pipe joint；Screw rod outer wall machined one section of screw thread, for being fastened by nut and sealing fluid
Companding footpath sub-assembly.High-pressure liquid medium is injected into the marmem pipe with interior muscle and connects by high-pressure liquid medium inlet
Head is internal, is realized with the overall, uniform of interior muscle marmem pipe joint by stepping up the pressure P of liquid medium
It is expanding.
The present invention in order that realize that high-pressure liquid medium is expanding with interior muscle marmem pipe joint, to above-mentioned left end
Lid and right end cap are further set：Left end cap and right end cap are provided with boss, for being connect with interior muscle marmem pipe
Head it is fixed and positioned；Marmem pipe joint two with interior muscle is respectively placed on the boss of left end cap and right end cap,
To reach the purpose of axial centre positioning.
The present invention reaches expected expanding amount, to upper in order that the marmem pipe joint with interior muscle is when expanding
Expanding scheme is stated further to be set：The interior expanding sub-assembly of muscle marmem pipe joint of band for installing good seal is placed in
In thick-walled pipe, thick-walled pipe is manufactured using high strength steel, and its intensity and wall thickness are sufficiently large, to ensure that thick-walled pipe is not produced when expanding
Elastic-plastic deformation.The internal diameter of thick-walled pipe determines according to the expanding amount size of pipe joint, to realize the precise control of expanding amount.
The solution have the advantages that：Expander is simple, compact, and installation and removal are convenient, can realize with interior muscle shape
Overall, the uniform expanding deformation of pipe joint of memory alloy, expanding amount controllable precise, and have to muscle in marmem pipe joint
There is protective effect.
