Dry Disconnect – 3" Coupler Maintenance
PACKING REPLACEMENT:
1.
With coupler BODY (10) securely held, assemble one WASHER (15)
and PACKING (17) over top of SHAFT (35), followed by an additional
WASHER (15). PACKING assembly must be installed with the “V”
notches of the PACKING pointing up towards you. WASHERS and
PACKING may be pushed into coupler BODY (10) using SCREW (4).
2.
Install SAFETY RELEASE BUTTON (42) and SPRING (40) onto coupler
BODY. Assemble WASHER (39) and WASHER, TEFLON (19) over
boss on BODY, making sure SAFETY RELEASE BUTTON (42) remains
underneath. Assemble BEARING (20) into RAMP (3) ID, then slide
RAMP & BEARING together onto boss on BODY. The hole in the
RAMP (3) must be facing the front (fixed jaw end) of the coupler
BODY. Push RAMP down until it locks together with LATCH (1).
Install WASHER (14) on top of RAMP (3).
3.
Thread JAM NUT (16) all the way to the top of SCREW (4). Thread
this combination into BODY over SHAFT (35). Tighten until you feel
it bottom out. Turn an additional quarter turn and back out a few
turns. Repeat this process once or twice (this helps set PACKING).
Finally, tighten SCREW (4) again until it bottoms out and then
snug tight.
4.
Holding SCREW (4) in final position, thread JAM NUT (16) down
SCREW (4) until it contacts WASHER (14), and tighten to
approximately 25 foot-pounds of torque.
5.
Place HANDLE EXTENSION (2) over SHAFT (35) end and down
onto RAMP (3). Cast flat in HANDLE EXTENSION must align with
flat on SHAFT.
6.
Place HANDLE (7) over SHAFT and nest it down between
the raised parts of the HANDLE EXTENSION (2). Wedging a screw-
driver in the slot of the HANDLE to open up the hole makes it easier
to slide the HANDLE over the SHAFT end. It may be necessary to
lightly tap HANDLE down with a hammer.
7.
Properly assembled, the HANDLE (7) will nest against
the HANDLE EXTENSION (2), and the HANDLE EXTENSION will nest
against the RAMP (3). Tighten SOCKET HD. SCREW (21).
8.
If it is necessary to replace SAFETY ADJUSTING SCREW (38),
uninstall CLAMP (11) by removing both SHOULDER SCREWS (32).
Take care not to lose SPRING (33). Remove JAM NUT (22) and
unthread SAFETY ADJUSTING SCREW (38) from CLAMP (11). Install
new SAFETY ADJUSTING SCREW (38) by threading all the way into
CLAMP (11) from its underside. Thread JAM NUT (22) onto SAFETY
ADJUSTING SCREW (38).
9.
Place SPRING (33) into the boss on CLAMP (11) and
assemble to BODY (10) with SHOULDER SCREWS (32). Tighten
SHOULDER SCREWS (32) to approximately 25 foot-pounds torque.
CLAMP (11) should rock freely back and forth.
COUPLER/ADAPTOR INTERFACE ADJUSTMENT:
This interface is critical to proper operation of the Drylok coupler.
Keeping the interface clean and adjusted will help maximize the life of
the coupler poppet seal and will reduce the chance of leaks developing
at the coupler / adaptor interface
1.
Loosen SAFETY ADJUSTING SCREW (38) and JAM NUT (22). Couple
dummy adaptor into fixed jaw of coupler BODY and turn HANDLE
(7) to first SAFETY RELEASE BUTTON (42) lock, as per operation
instructions.
2.
Use a flathead screwdriver to tighten SAFETY ADJUSTING SCREW
(38) until it makes contact with RAMP (3). Then, continue to tighten
one complete turn. Push SAFETY RELEASE BUTTON (42) and turn
HANDLE (7) to full “open” position. Next, holding the SAFETY
RELEASE BUTTON (42) down, turn HANDLE back and forth two or
three times to properly seat SAFETY ADJUSTING SCREW (38).
3.
Now turn HANDLE (7) and lock in full “open” position. Loosen
SAFETY ADJUSTING SCREW (38), backing it completely off RAMP
(3). Retighten SAFETY ADJUSTING SCREW (38) until it just makes
contact with RAMP. Tighten SAFETY ADJUSTING SCREW one and a
quarter to one and a half turns or approximately 18 inch-pounds
of torque.
4.
Tighten JAM NUT (22) down against CLAMP (11) to lock SAFETY
ADJUSTING SCREW in place.
WARNING
Failure to retighten JAM NUT (22) over the
SAFETY ADJUSTING SCREW (38) may cause coupler/adaptor
interface leakage and/or coupler failure.
TEST PROCEDURE:
It is recommended that the VALVE be pressure tested utilizing the air
under water method, checking for leaks in the area of the O-RING,
POPPET (36) and PACKING (17). Place coupler under water, tapping
and rotating it to release any trapped air. Pressurize the valve to 2 PSI,
and check inspection points. Then, increase pressure to 80 PSI and
check inspection points again. Check for leaks in the following areas:
A)
RAMP (3)/HANDLE EXTENSION (2) area.
B)
POPPET (9)/coupler interface (hold coupler vertically,
with POPPET (9) face up and fill coupler face with water).
Reduce air pressure to 0 PSI. Insert Drylok test fixture into coupler.
Note: The Drylok test fixture is a fully operational, leak-proof adaptor,
fitted with a nipple and cap. Depress SAFETY RELEASE BUTTON (42),
open coupler to fully open position and pressurize to 2 PSI. Check for
leaks at the inspection points listed above. Also check for leaks at
the coupler/adaptor interface. Increase pressure to 80 PSI and check
for leaks again. If leaks occur at coupler/adaptor interface, retighten
adjusting screw as stated above and retest.
