Two, as shown in Figure 8,9, traction-resistant fibre 20 in RTP tube road tensile layer 3 is removed, threading clip b is caught in RTP tube a
On the step surface milled out, and pay attention to anchored end 8 backwards to pipe hot melting interface.
Three, RTP tube inner tube 1 is subjected to sweat soldering, and removes thermofussion welding junction superfluous molten material.
Four, the traction-resistant fibre 20 separated is sequentially passed through into the corresponding threading hole of threading clip b, as shown in figure 8, tension is fine
Dimension 20 initially passes through clip inner ring threading hole 6, then passes back through outer ring threading hole 7 and use anchor clamp d that traction-resistant fibre 20 is free
End is fixed at the anchored end 8 of threading clip b.
Five, the position for adjusting threading clip b, is allowed to match with the card slot 14 of connector housing c, by 20 anchor of traction-resistant fibre
It reinforces.
Six, opposite be mounted on of two halves connector housing c is threaded outside clip b and RTP tube a, makes 14 position of card slot and threading
Clip disk body 5 is corresponding, two halves button and securely after, fastened using 21 butt joint housing c of fastening bolt group, and complete outside connector
The connection of set.
Seven, it is injected into connector housing inner cavity 12 often using glue injection equipment by the injected hole 13 on an end connector housing c
Temperature solidification unsaturated polyester (UP) or epoxy resin colloid uniformly fill full housing inner cavity 12 to colloid, and in other end injected hole 13
There are homogeneous colloids, when bubble-free stops slip casting.
Eight, after the colloid solidification in housing inner cavity 12 and after reaching design requirement, using the methods of welding or be bolted
Both ends injected hole is blocked, connector assembly is completed.
Connector is when in use as shown in fig. 6, the axial tension of RTP tube body a is transferred to threading clip b by traction-resistant fibre 20
On, then it is transferred on connector housing c by threading clip b, is born to occur during conduit running by the connector housing c of steel
Tensile stress.The interior pressure of pumped (conveying) medium in RTP tube a, is transferred on the colloid in housing inner cavity 12, and by colloid by RTP inner tube 1
It is transferred on connector housing c, the interior pressure of medium in pipe is finally undertaken by steel joint housing c.
Meanwhile the colloid solidified is uniformly wrapped in the outside of pipe hot melting docking area 22, and by traction-resistant fibre 20 and
Anchor clamp d at anchored end 8 is equally uniformly wrapped up, and plays good protection and sealing function.Pipeline internal medium does not contact connector
Housing c, therefore pipeline resistance dielectric corrosion ability is strong, it is low to media chemistry component requirements.
In addition to the implementation, the utility model can also have other embodiments.It is all to use equivalent replacement or equivalent change
The technical solution to be formed is changed, the protection scope of the requires of the utility model is all fallen within.
