3) Positioning installation points
>> V method
The line between two transducers is parallel to pipe axis, and equal to the distance
shown in the
converter. As shown, A, B are the two installation points.
>> Z method
1. Firstly according to the installation distance shown in converter, positioning two points A, C
on the same side of pipeline. AC is parallel to pipe axis.
2. Perpendicular to the pipe axis, opposite to point C, get Point B.
3. Check. Measure the length between A and B from both sides of the pipe, get AB
1
and AB
2
. If
AB
1 =
AB
2,
then B is the correct point. If not, need to positioning point B and C again.
As shown, A, B are the two installation points
4) Fix ball valve base
>> Welding Fix
For carbon steel pipes, the ball valve base can be welded directly. Make sure that the
central point of ball valve base is overlapped with the transducer installation point.
Matters need attention:
·
Please take the PTFE sealing gasket out from the base before welding.
·
Please clean the pipe surface around welding point before welding. Pay
attention that there
should not be any air hole during welding, which can avoid leaking. Welding
strength must
be ensured.
· Do not sputter welding slag on the base thread.
· Non-deformation of base during welding.
After welding, tighten ball valve into the base.
