outer surfaces with a brush. Do not leave the valve in the washing liquid
for a long time. After washing you should wipe the valve dry with a clean
rag. Before installing it back in the well sounder, apply a small amount of
lubricant, according to standard CIATIM GOST 6267-80, on the rubber
sealing ring surface (5).
After mounting the valve on the well sounder, install the latter on
the Inspection bench for well sounders SKU-1 IZM 4.137.003 (SIAM
Company) and purge the valve at pressure of 5…8 atm, using clean air.
Test for pressure integrity with a soap solution. A slight “seepage” is
allowed with small bubbles in the discharge hole area. In case of a high
"seepage", repeat the valve washing process.
If high “seepage” continues, then replace the cone (7) of ball seats.
In order to do that, press the retaining ring (3) and pull it out of valve
housing. Take out the guide bush (1), spring (4), tappet (2) in combination
with cone (7) and nut (6) from valve housing (8). Then, replace the cone
(7) by unscrewing the nut (6). When necessary, clean the contact chamfer
of the valve ball-and-seat in the housing (8) with a rag.
Assemble it in the reverse sequence.
