Features:
1) Used together with submerged oil-pump type fueling machine
2) Can cut off the oil flow automatically and rapidly and is a protection for
submerged oil-pump type fueling machine
3) Adopts fusible material and cutting ring
4) Valve core will close automatically to cut off oil-flowing pipe in case of
catching fire or oiling machine damaged by knocking
5) Threaded outlet of upper body is convenient for connection with the inlet
of flowmeter of fueling machine
6) High temperature pressure relief valve is used to relieve the pressure
increasing with the temperature of oil in the pipeline due to the cut-off of
cutting ring and close of auxiliary valve when oiling machine breaks down
7) Normally open type, auxiliary valve can stop oil reverse flowing and leaking
when it is closed
8) The holder can make auxiliary valve normally open to reduce the resistance
of oil flow and that will not affect its flux
9) Spring is used to strengthen sealing performance when auxiliary valve closes
10) Cutting ring is cut off under stress and ensures the cutting-off moment of
350 - 550N.m
11) Main valve is used to close the oil flow to oiling machine from submerged
oil pump
12) Main body is made of HT200 cast iron and inside or outside threaded inlet
is for your option
13) Testing jack is used to test the pressure in pipeline after being installed
with a pressure meter
14) Tumbler is a holder to keep main valve normally open. Using special alloy
YINHE 1# and YINHE 2# can ensure the normal action under 190 oC
or 75 oC (low temperature type)
