ABSTRACT:
This invention relates to a hose clearing device and more particularly to a hose clearing device which fits on the hose and may receive compressed air therethrough.
BACKGROUND OF THE INVENTION
When storing items for the winter, it is necessary to remove the fluid, especially undesired fluid, therefrom. Typical items, from which fluid must be removed, include fluid lines on motor homes, garden hoses and similar fluid containing items. One good way of accomplishing such a fluid clearance is to run air therethrough. However, there is no efficient way to do that.
Typical of the underfed fluid in these hoses or elongated tubes is water. Because water expands in volume as it transitions to ice, such expansion can cause the hose to rupture, and the hose to be ruined.
On ships of the United States Navy, it is customary to use hoses to apply steam to pipes for the purpose of cleaning the pipes. Customarily, such hoses are stored on deck. Condensed water in the hoses can freeze and make the hoses difficult to use. In fact, such frozen condensate can even ruin the hoses. An efficient clearing of those hoses can provide a great advantage. No such clearing device or method exists.
It is also feasible to put antifreeze in the appropriate lines. However, the antifreeze can have difficulty. Not only is the antifreeze an environmental hazard, it is difficult to dispose of after use. Thus, a means for clearing the fluid out of lines is desirable.
SUMMARY OF THE INVENTION
Among the many objectives of this invention is the provision of a fluid clearing device in the form of a valve assembly, capable of being removably attached to the elongated fluid container in air tight fashion.
Another objective of this invention is to provide a valve assembly to assist with passing air through an elongated member.
Yet another objective of this invention is to provide a valve assembly attachable to a male hose fixture.
Still, another objective of this invention is to provide a valve assembly attachable to a female hose fixture.
Additionally, an objective of this invention is to provide a valve assembly attachable to a hose without a fixture.
A further objective of this invention is to provide a valve assembly attachable to a hose with a snap assembly.
A still further objective of this invention is to provide a valve assembly attachable to a variety of hoses with an adapter.
Yet a further objective of this invention is to provide a valve assembly attachable to a steam hose in order to remove condensate therefrom.
These and other objectives of the invention (which other objectives become clear by consideration of the specification, claims and drawings as a whole) are met by providing a valve assembly having at one end thereof, for example, a compressed air receiving valve; and, at the opposing end thereof, an attaching device for securing the valve assembly to an elongated tube requiring the substantial evacuation of fluid therefrom.
