Water Knock Out Bottle and Process for Making the Same
Apparatus for stopping fluid flow when liquid is present in the fluid flow. The apparatus generally includes two parts, an internal structure with a float valve, and an external tank. The internal structure includes a plurality of fluid entry holes positioned, sized, and numbered relative to a drain hole. The design is generally thread less, and the preferred process used for making the apparatus includes welding and promotes the conservation of materials.
This application is a continuation of non-provisional application Ser. No. 13/361,133, filed on Jan. 30, 2012, which claims the benefit of provisional application No. 61/437,794, filed on Jan. 31, 2011.

BACKGROUND OF THE INVENTIONThe present invention is in the technical field of apparatuses that stop fluid flow when liquid is present in the flow. Specifically, the present invention is ideal for use as a water knock-out bottle in the oil and gas industry. When operating with the forces and pressures of a gas well, threaded solutions tend to fail. What is needed is a welded solution that can be constructed in a cost effective and economical manner.
SUMMARY OF THE INVENTIONThe present invention is a generally thread-less automatic shut-off apparatus that stops fluid flow when liquids are present in the flow, and the process that is used to create the apparatus. The apparatus generally comprises two main components: an external tank with an inlet flange and a drain; and an internal float valve with an exit flange. The process includes welding and creating the internal float valve using parts from the creation of the external tank. The internal structure, or float valve, has a particular configuration and size of fluid entry and drain holes.

The advantages of the present invention include, without limitation, a generally thread-less solution for water knock out bottles used in the oil and gas industry. A thread-less solution is less likely to fail during its service.
In broad embodiment, the present invention is a generally thread-less apparatus that ensures that only gas flows through it, and stops fluid flow when liquid flows into the apparatus. Further, the present invention is a process of making a generally thread-less apparatus that ensures that only gas flows through it, and stops fluid flow when liquid flows into it. The process relies on welding instead of using threaded parts.
While the foregoing written description of he invention enables one of ordinary skill to make and use what is considered presently to be the best mode thereof, those of ordinary skill will understand and appreciate the existence of variations, combinations, and equivalents of the specific embodiment, method, and examples herein. The invention should therefore not be limited by the above described embodiment, method, and examples, but by all embodiments and methods within the scope and spirit of the invention.
Claims
1. A water knock out bottle comprising:
- an external tank having an inlet, a drain valve, and a top opening;
- an internal chamber fitting inside said top opening, wherein said internal chamber includes at least one drain hole, a plurality of fluid entry holes, and an exit opening; wherein said plurality of fluid entry holes are positioned between said exit opening and said drain hole, and said plurality of fluid entry holes have a combined size greater than fifteen of at least one drain holes.
- a float receptacle positioned inside said internal chamber between said plurality of fluid entry holes and said exit opening;
- a float placed inside said internal chamber;
- said float receptacle and float having shapes so that when said float is in contact with said receptacle, fluid cannot pass through said exit hole.
2. The water knock out bottle of claim 1 wherein said inlet and exit openings are flanges for connecting to two inch pipe.
3. The water knock out bottle of claim 1 wherein said external tank is created by welding weld caps to the ends of a pipe.
4. The water knock out bottle of claim 3 wherein said pipe has a six inch diameter.
5. The water knock out bottle of claim 3 wherein said internal chamber is welded to said external tank.
6. The water knock out bottle of claim 1 wherein said inner chamber comprises a flange welded to an entry fitting, a bushing welded to said entry fitting, an elongated hollow cylinder welded to said bushing, and a seat welded to said bushing on the inside of said elongated cylinder.
7. The water knock out bottle of claim 1 wherein said float has a specific gravity less than one and outer surface of stainless steel.
8. The water knock out bottle of claim 1 wherein said float's cross section area is at least eighty percent of the cross section area of the section of said internal chamber where said float will travel.
