Liquid filler

Abstract

An improved construction of a liquid filler comprised of a filling body, a ball valve, and a mobile lid shutter that executes automated and precise filling operation in 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, and 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.

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 ...

Benefits of technology

[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.

Problems solved by technology

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.
