Description
BACKGROUND OF THE INVENTION
[0001] (a) Field of the Invention
[0002] The present invention is related to a liquid filler to load
volatile oil from oil tank to an oil barrel, and more particularly,
to one that prevents accidental flame breaking out in the barrel
from extending into the oil tank.
[0003] (b) Description of the Prior Art
[0004] Whereas a filler of liquid is essentially used in
distributing oil from oil tank into an oil barrel, gas generated
from the volatile oil in the course of transport will increase the
pressure inside the oil barrel. An exhaustion pipe is separately
provided to collect the gas above the liquid level inside the
barrel into another barrel for reuse. A liquid filler 2 of the
prior art as illustrated in FIG. 1 of the accompanying drawings has
one end installed at a terminal of an oil pipeline 3 extended from
an oil tank and another end inserted into a liquid inlet 41 of an
oil barrel 4. A flow-regulating valve 22 is disposed to a middle
section of the filler 2 to control the oil S flowing into the
barrel 4. Exhaustion and collection installations generally
available include an exhaustion pore 211 provided on one side of a
lower section of a liquid outlet pipe 21 extending into the liquid
inlet 41 of the barrel 4; a rear end of the filler 2 extends to
connect to a connection pipe 23 for gas collection and turns to
extend into the liquid outlet pipe 21 for series connection to
define a pathway for oil gas S1 separately provided on the inner
side of the liquid outlet pipe 21. Accordingly, oil gas S1
generated above the level of the oil is pushed to the exhaustion
pore 211 and externally discharged through a gas outlet 212 and the
connection pipe 23.
[0005] However, the connection pipe 23 for discharging and
collection the oil gas S1 and the filler provided with a flow
regulating valve 22 in the construction of the liquid filler of the
prior art are separately provided to consume additional space and
cause barrier to the hands of the operator. Furthermore, the tail
of the connection pipe 23 must be curved to extend into the
exhaustion pore 211, and the air outlet 212 before a total welding
job to where the tail of the connection pipe 23 enters into the
exhaustion pore 211 and the air outlet 212 that involves extra time
and inconvenience in the process. Defects frequently found at where
the soldering job is provided lead oil S leakage from the
peripheral of the soldering seam.
[0006] Furthermore, the liquid outlet pipe 21 of the filler is
open-end to easily attract the flame in case of accidental ignition
of the oil in the barrel 4 to extend back into the oil tank for
causing more serious explosion.
SUMMARY OF THE INVENTION
[0007] The primary purpose of the present invention is to provide
an improved construction of a liquid filler that features a summary
structure of having an oil flow control valve and oil exhaustion
channel installed on a same filler body for achieving economic and
practical benefits by lowering production cost and minimizing
failure. To achieve the purpose, the present invention includes a
filling body containing a hollow valve chamber; a ball valve
disposed at the upper end of the filling body is provided with an
axial bolt to execute turning direction around a fixed axial; a
liquid inlet and a downward liquid outlet provided sideway at the
middle section connect through the ball valve to receive oil
introduced through a liquid receiving pipe disposed on one side of
the filling body; the lower section of the valve chamber is made
downward; a liquid drain pipe provided with a coupling seat is
externally disposed to the middle section of the valve chamber; a
liquid drain channel to receive oil from the oil outlet of the ball
valve and lead the oil to flow into an oil barrel placed below the
liquid filler, and an exhaustion channel with a closed terminal are
segregated inside the liquid drain pipe; an oil gas inlet is
disposed on one side of the lower section of the exhaustion channel
and an oil gas outlet externally connected to an oil gas outlet is
disposed on the upper section of the exhaustion channel for
discharging volatile oil gas present above the liquid level in the
oil barrel along the exhaustion channel.
[0008] Another purpose of the present invention is to provide an
improved construction of a liquid filler that provides safety
protection benefits by cutting off flame of any accidental ignition
of the oil in the barrel from extending back into the oil tank. To
achieve the purpose, a drooping mobile lid shutter is disposed by
having its top pivoted to a mouth at the bottom of the liquid drain
channel in the lower section of the filling body; the mobile lid
shutter is connected to a tension coil suspended in and extending
from the inner side of the liquid drain channel; and the mobile lid
shutter normally blocks the mouth of the liquid drain channel in
the absence of executing liquid discharge by the mobile lid
shutter.
[0009] Another purpose yet of the present invention is to provide
an improved construction of a liquid filler that executes automated
and precise filling operation. To achieve the purpose, once the
coupling seat moves further to cover up the liquid inlet of the
barrel in position, a plate retainer at the top of the mobile lid
shutter protruding from where behind the pivoting location at the
top folds up for holding against the edge of the liquid inlet of
the barrel, in turn synchronously opens up a front section of the
mobile lid shutter to automatically open up the mouth of the liquid
drain channel; and when the coupling seat upward clears away from
the mouth of the liquid inlet of the barrel, the plate retainer for
no longer holding against the edge of the liquid inlet of the
barrel folds downward to return to its normal status of shutting up
the mouth of the liquid drain channel.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0015] Referring to FIGS. 1, 2, 3, and 4, an improved construction
of a liquid filler of the present invention is essentially
comprised of a filling body 5, a ball valve 6, and a mobile lid
shutter 7.
[0016] The filling body 5 contains at its middle section a hollow
valve chamber 51 provided with a bolted opening at its top; an open
liquid inlet 52 is provided on one side of the valve chamber 51 for
an outer end of the liquid inlet 52 to be connected to a liquid
pipe 55 extending from an oil tank so to allow oil S delivered form
the tank to enter into the valve chamber 51 through the liquid
inlet 52; a lower section of the valve chamber 51 is directed
downward; and a liquid drain pipe 53 connected to a coupling seat
531 to an oil barrel 4 is externally disposed to the middle section
of the valve chamber 51.
[0017] The ball valve 6 inserted in the valve chamber 51 is
provided at it top a regulating axial bolt 61 to pass through a
bolting hole 541 disposed in a middle section of a locking lid 54
located at where above the valve chamber 51 for the ball valve 6 to
execute turning its direction around a fixed axis when a handle 62
is connected to the ball valve 6. The middle section of the body of
the ball valve 6 is made a sideway liquid inlet 63 that connects
through a downward liquid outlet 64 to receive the volatile oil S
introduced from a liquid receiving pipe 55 provided on one side of
the filling body 5. A liquid drain channel 532 directed downward to
receive liquid delivered through the liquid inlet 63 of the ball
valve 6 is segregated in an inner section of the liquid drain pipe
53, and the terminal of the liquid drain pipe 53 is related to a
closed exhaustion channel 533. An inlet 5331 for an oil gas S1 is
disposed on one side of a lower section of the exhaustion channel
533, and an outlet 5332 to drain the oil gas S1 externally
connected to a gas-leading pipe P is disposed in an upper section
of the exhaustion channel 533. Accordingly, the volatile oil-gas S1
above the oil level of the oil S is externally led along the
exhaustion channel 533 to achieve the purpose of providing a
summary construction of having a flow control valve (i.e., the ball
valve 6) for the oil S and a drain channel for the oil gas S1
(i.e., the exhaustion channel 533) disposed on the same filling
body 5.
[0018] The mobile lid shutter 7 is pivoted to an upper section of a
mouth at a bottom end of the liquid drain channel 532 by means of a
lateral bolt 71 disposed on its top and further connected to a
tension coil 72 extending out of the inner side of the liquid drain
channel 532 so that the mobile lid shutter 7 normally shuts up the
mouth of the liquid drain channel 532. A plate retainer 73
protrudes from the top of the mobile lid shutter 7 at where behind
the pivoting location of the lateral bolt 71.
[0019] Accordingly, as illustrated in FIG. 4, before the coupling
seat 531 moves to a locating position to fully cover up a liquid
inlet 41 of the barrel 4, the mobile lid shutter 7 normally shuts
off the mouth of the liquid drain channel 532 when the tension coil
72 is pulled up and the oil S delivered from the oil tank is
prevented from being led downward even the liquid inlet 63 of ball
valve 6 has been turned to align at the liquid inlet 52 of the
filling body 5.
[0020] Once the coupling seat 531 moves further to cover up the
liquid inlet 41 of the barrel 4 in position as illustrated in FIG.
5, the plate retainer 73 at the top of the mobile lid shutter
protruding from where behind the pivoting location at the top folds
up for holding against the edge of the liquid inlet 41 of the
barrel 4, and in turn synchronously opens up a front section of the
mobile lid shutter 7 to automatically open up the mouth of the
liquid drain channel 532. The oil S is downward led to enter into
the barrel to complete the purpose of filling the oil S into the
barrel 4 when the liquid inlet 63 of the ball valve is turned to
align at the liquid inlet of the filling body 5.
[0021] As illustrated in FIG. 4, when the coupling seat 531 upward
clears away from the mouth of the liquid inlet 41 of the barrel or
the barrel 4 turns over for the coupling seat 531 to automatically
disengage from the mouth of the liquid inlet 41, the plate retainer
73 for no longer holding against the edge of the liquid inlet 41 of
the barrel 4 folds downward to return to its normal status of
shutting up the mouth of the liquid drain channel 532 to prevent
the oil S from being further led into the barrel 4 to provide
safety protection benefits, i.e. the most important characteristic
of the present invention in case of an accidental ignition breaks
out inside the barrel 4 by cutting off extended ignition of fire or
explosion since the fire is prevented from spreading through the
liquid drain channel 532 back to the filler and the oil tank at the
front end of the filler.
