FIG. 2 andFIG. 2 a, two separate internal structures are shown.FIG. 2 a represents an internal structure that is made with commercial off-the-shelf parts. - Referring now to the invention shown in
FIG. 2 , internal structure is shown that is made from one continuous piece. The internal structure includes aflange 9 capable of being attached to another flange that is not part of the system, so that the apparatus may be installed in-line. in typical gas wells. This is true of all flanges described in this document. The internal structure also includes anelongated cylinder 7. In this embodiment,flange 9 andcylinder 7 are one continuous piece of metal, but they can be separate pieces welded together.Cylinder 7 has an opening at the top. Insidecylinder 7 isseat 41. Seat 41 is configured so thatball 70 cannot pass throughflange 9, but fluids can. Whenball 70 is in contact withseat 41, a seal is created so that fluid cannot pass throughflange 9. - Referring now to
FIG. 2 a, the internal structure is created using off-the-shelf parts.Exit flange 10 is welded tocoupling 20. In the preferredembodiment exit flange 10 is a 2″ diameter 300# flange, andcoupling 20 is a 2″ diameter socket weld coupling. In the preferred embodiment, coupling 20 is welded tobushing 30. Here, bushing 30 is a 2″ diameter×1″ bushing.Bushing 30 is welded tonipple 35. Here,nipple 35 is threaded so thatfemale union 40 may be attached tonipple 35 using threads. However, the invention is not limited by the use of threads, asnipple 35 may be welded tofemale union 40. In the embodiment shown inFIG. 2 a,Female union 40 is a 1″ diameter threaded female union, andnipple 5 is a 1″ Diameter by 4″ threaded nipple. Also welded tobushing 30 isinternal pipe 5. In the preferred embodiment,internal pipe 5 has a 2″ diameter. Finally, the bottom ofinternal pipe 5 is sealed by seal means 8. In the preferred embodiment, seal means 8 is a 2″ diameter circular piece of metal welded to the bottom ofinternal pipe 5. - Referring to
FIGS. 2 and 2 a,top holes 50 are cut out ofcylinder 7 andinternal pipe 5 so that fluids can enter the internal structure. In the embodiment shown inFIG. 2 a, there are two rows of 9½″ holes for a total of 18 holes that are installed so that the center line between the rows of holes is 6″ belowbushing 30. Further,bottom hole 60, also called a drain hole, is cut out ofcylinder 7 so that liquid can escape the internal structure when the liquid is drained from the system viad 110. In thepreferred embodiment hole 60 is a ½″ hole. Through experimentation, the optimal ratio ofbottom hole 60 overtop holes 50 was found to be approximately 1/18. This ratio allows for gas to flow through the internal structure without disturbingfloat 70. As the ration becomes larger, gas entering throughbottom hole 60 may pushfloat 70 into its seat and stop fluid flow when water is not present. When claimed, the size of openings me s the surface area of the space of the openings. The size of all top openings means the combined surface area of all top openings. - Still referring to
FIGS. 2 and 2 a, in the preferred embodiment, float 70 is a ball that has a specific gravity of slightly less than one. In the preferred embodiment, float 70 is stainless steel, or some other type of material that resists corrosion.
