Characteristic Use: The emergency cut-off valve is installed on the
inlet of the pipeline for the submersible pump type fuel dispenser.
In case of accidents, for instance, the dispenser collapsing or a
fire, the valve can rapidly cut off the oil flow automatically.
Installation: Install the oil pipeline with oil-proof pipes which
will not turn hardened, The screw seal adopts thread sealant. The
tightness should not be excessive. Don't screw on the slot, or else
the valve will be twisted off. Fix the hexagonal screw on the top
of the valve with a spanner and screw the joint with another
spanner. The slot must be on a level with the top of the base or
within 10mm above or below. Otherwise, the slots on the inlet and
outlet are possible to be broken off caused by the heavy strike.
Change of the top slot: Shut off the power supply for the oil pump
and oil drainage system. Manually close the valve, take off the
hexagonal screw, pull out the valve top, take down the gasket,
spread butter on, mount a new valve top and tighten the hexagonal
screw. Change those parts with even slight damages. Load the pipes
in the oil distributor again and check whether there is any oil
leakage. Valve maintenance: Open and close the valve manually
several times and restore to the former position again to confirm
whether the valve can operate normally. Such operation must be
conducted annually to check whether there are any damage to the
valve and whether repair is necessary or not. Main Part
