12 Claims. (Cl. 251-91) This invention relates to a device for controlling the iiowl cf fluid, and relates more particularly to a ow bean for controlling the flow of a well.

The oil flowing from wells producing from natural causes is usuallyI under comparatively high pressures, making it necessary to control or regulate the ow. Devices commonly known as flow beans are employed to control or restrict the rate of flow of wells. The oil owing from Wells under high pressures usually carries with it sand which rapidly cuts out and enlarges the bores or passages of the usual types of ilow beans, making it necessary to replace them after short periods of use.

It is a general object of the present invention to provide a simple, practical, and eective ow bean or ow lnipple for controlling the flow of uid from an oil well, or the like.

Another object of the invention is. to provide a flow bean in which the nipple for reducing the rate of flow of.the fluid may be quickly and easily removed for replacement. Y

It is another object of the invention to provide a flow bean in which the nipple for controlling or reducing the rate of flow may be quickly and easily replaced without removing the device from the line and without disconnecting or disturbing other equipment on the well.

It is another object of the invention to provide a flow bean of the character mentioned that is adapted to handle extremely high pressures without leaking.

A further object of the invention is to provide F a ow bean in which the flow controlling nipple directly subjected to the abrasive action of the fluid and the sand in the fluid is of simple formation and is inexpensive of manufacture.

It is another object of the invention to provide a flow bean that maybe simultaneously operated to cut of the flow of fluid and to operate the ow controlling nipple to a position for removal in a single operation.

Another object of the invention is to provide a. flow bean that embodies a carrier for the ilow nipple that is rotatably carried in a body, so that the nipple is shiftable to a position forreplacement and to provide a means for effectively sealing around the carrier.

It is a further object of the invention to provide a ow bean that is dependable in operation and that is inexpensive of manufacture.

Other objects and features of my invention will be best and more fully understood from the following detailed description f a typical form and application of the invention, throughoutl which description reference is had to the accompanying drawings, in which:

Fig. 1 is a side elevation of a typical arrangement of ttings or valves at the upper end of a well casing illustrating two of the flow beans provided by the present invention in connection therewith. Fig. 2 is a top or plan view of the flow bean provided by this invention. Fig. 3 is an end view of the device. Fig. 4 is an enlarged 65 vertical detailed sectional view'of the flow bean illustrating it in the open position. Fig. 5 is a transverse or horizontal detailed sectional view taken as4 indicated by line 5-5 on Fig, 4, and Fig. 6 is a reduced horizontal detailed sectional 7 0 view taken as indicated by line 6-6 on Fig. 4.

In Fig. 1 ofthe drawings I have illustrated an arrangement of conduits, valves, and other ttin'gs for mounting at the upper end of a well casing, which arrangement may be considered typical of constructions provided on producing oil wells. Devices or arrangements ofl the general character illustrated in Fig. 1 of the drawings are generally termed Christmas trees. The Christmas tree shown in the drawings includes the upper end portion-of a well cap or head 10, a gate Valve l1 connected with the upper end of the head 10, a cross tting 12 above the gate valve 11, a valve 13 on the upper arm of the tting 12, a valve 14 on one of the side or horizontal arms of the fitting 12, a valve 15 on the other horizontal arm of the fitting, and various other parts common to arrangements of this character.

The deviceor ow bean provided by the present invention is intended primarily to be mounted in or connected with a conduit for passing oil from a producing well. For the purpose of facilitating an understanding of the invention the flow bean will be described as connected with the valve 14. In Fig. 1 of the drawings I have illustrated 95 two flow beans provided by this invention, one being connected with the valve 14 and the other being connected with the valve 15. The device provided by this invention is adapted to be employed wherever it is desirable to control the dow of fluid under high pressures. It is to be understood that the invention is not to be taken as limited to the particular form or applicationabout to be described, but that it is to be taken asincluding any features that may fall within the scope of the claims.

The flow bean provided by the present invention includes, generally, a body 16 having a iluid passage 17, a core or plug 18 carried by the body 16, a flow nipple 19 removably carried. by the 110 plug 18 and adapted to restrictl the flow of uid through the passage 17, and means 20 for sealing around the plug 18 to prevent the leakage of iluid from between the body 16 and the plug 18.

The body 16 is adapted to be mounted in or connected with a conduit at the upper end of a well. For example, it is adapted to be connected with the valve 14 on the fitting 12. The body 16 may be similar, generally, to the body of a typical stop cock and may be varied considerably in construction Without departing from the broader principles ofv the invention. The iluid passage 17 extends diametrically through the body 16 and suitable means is providedat the opposite ends of the passage for connecting the body 16 in a fluid conduit. In the particular case illustrated externally screw threaded tubular extensions 21 are provided on the body 16 at the opposite ends of the passage 17 A longitudinally tapered opening 22 is provided in the body 16 for carrying the plug 18. The opening 22 preferably extends completely through the body and intersects the fluid passage 17. The central longitudinal axis of the opening 22 is preferably normal to the longitudinal axis 'of the passage 17. The

opening 22 is round in cross section and is longitudinally tapered throughout its length.

In accordance with the invention a second opening 23 is provided in the body 16. The opening 23 intersects the opening 22 and its central longitudinal axis is in the same plane as the longitudinal axis of the fluid passage 17. The opening 23 extends completely through the body 16 and may be of greater diameter at one side of theopening22 than it is at the opposite side of the opening 22. The opening 23 may be normally closed at its largest end by a removable plug 24 and at'its smaller end by a removable -plug 25.

The core or plug 18 is rotatably carried in the opening 22 and is in the nature of a carrier for the ow nipple 19. The plug 18 is operable tov a position where it prevents the flow of fluid through the passage 17. In accordance with the preferred form of the invention the plug 18 is an integral member and includes a longitudinally tapered central portion 26 tting the opening 22, an enlarged polygonal portion 27 at the large end of the central part 26, and a reduced portion or stem 28 at the small end of the portion 26. The central portion of the plug is of round cross sectional conguration and preferablyhas a ground twith the opening 22 so that it tightly fits the opening.

The polygonal portion 27 of the plug 18 projects from the body 16 and is adapted to be engaged by a .wrench or suitable tool for operating or turning the plug. The portion 27 may be made hollow to lighten the construction. `A transverse opening 29 may be provided through the portion 27 to receive a suitable tool for operating the plug. In the preferred form of the invention the end of the body 16 at the base of the portion 27 is made flat and an annular flange 30 is provided at the base of the portion 27 to extend over the end of the body. In practice the flangev30 i`s"1or mally spaced from the body.

The flow nipple 19 is removably carried in a transverse opening 31 in the plug 18. The opening 31 is diametrically disposed in the central portion 26 of the plug and is provided at a point where 1t is adapted to be brought into register with the fluid passage 17. The opening 31 extends completely through the plug 18 and is longitudinally tapered throughout `its length. The

Vremoval of the nipple 19.

nipple 19 is in the form of a liner or tube having a central longitudinal opening 32. The. opening` 32 of the nipple maybe of a diameter to provide for the desired restriction of the flow of fluid through the passage 17. The nipple 19 is carried completely within the opening 31 and is longitudinally tapered. In the preferred form of the invention an annular radial flangel 33 is provided at the small end of the nipple to fit the opening 31. An annular body 34 of packing surrounds the nipple between the flange 33 and the large end of the nipple. The packing 34 may be formed of a suitable soft metal or rubber and is provided to seal with the Walls of the opening 31. The packing 34 prevents the nipple 19 from becoming set or jammed in the opening 31.

The large end of the opening 23 in the body is adapted to readily pass the nipple 19 when it is desired to insert or remove the nipple. It will be obvious how thefplug 18 maybe operated from a position such as is shown in Figs. 4 and 5 of the drawings to a position where the opening 31v is in register with'the opening 23 and how the plugs 24 and 25 may be removed to permit When the plug 18 is in a position where the nipple may be removed, that is, when the opening 31 is in register with the Aopening 23, the 110W of fluid through the passage 17 is fully stopped by the plug.

The present invention provides means for limiting rotation of the plug 18 in the opening 22 so that it may be positioned where the nipple 19 is in proper register with the passage 17. The means for limiting the movement of the plug 18 in the opening 22 includes a lug 35 projecting from the body 16 and extending `into a groove 36 in the base of the polygonal portion 27 of the plug. The groove 36 may extend for approximately about the axis of rotation of the plug 18, vand the lug 35 is adapted to engage an end of the groove when the plug is in a position where the nipple 19 is in direct register with the fluid passage 17. The lug 35 is adapted to engage the opposite end of the groove 36 to position the plug relative to the body so that the opening 31 is in register with the opening 23.

Means may be provided on the plug to indicate the direction in which the flow is intended to pass through the device. In the particular form of the invention illustrated in the drawings an arrow.

40 is provided on the end of the polygonal portion 27 to indicate the direction of flow through the plug 18.

The means 20 is provided to pack or seal between the body 16 and the plug 18 and to maintain the plug in a position where it is tightly seated in the opening 22. The means 20 includes packing 41 arranged in an enlargement or groove 42 in the large end portion of the opening 22 in the body. The packing is preferably in the nature of a cup-leather. The lower side of the enlargement or groove 22 is beveled inwardly toward the' seals with the walls of the enlargement 42 and the shoulder. Y

In the preferred form of the invention an annular groove 44 is provided in the inner wall of the packing 41 to receive uid supplied to the groove 22 from the exterior of the body. Means 'l is provided for supplying fluid under pressure to the groove 22 for actuating the packing 41 into effective sealing engagement with the Walls f the groove and the flange or shoulder 43. A suitable valved fitting 70 is arranged in a port or passage 71 communicating with the groove 22. A suitable fluid, say grease, may be delivered to the groove 22 through the fitting 70 to actuate the packing 41 and to retain the packing compressed against the shoulder 43 and the walls of the groove.

Means is provided for sealing or packing between the reduced end portion of the plug 18 and the body 16. Registering annular grooves are provided in the plug 18 and the opening 22 to form an annular groove 46 for carrying a packing or cup-leather 47. The walls of the groove 46 diverge downwardly or outwardly and the packing 27 is provided with flanges 48 to seat against the divergent walls of the groove. The inner portion of the groove 46 is adapted to hold or contain uid supplied to the groove 46 under pressure to eiectively expand the anges 48 against the walls of the groove. A passage 74 extends from the exterior of the body 16 to the groove 46 and a suitable valved fitting '75 is provided at the outer end of the passage, through which grease or the like, may be supplied to the groove for actuating the packing.

In the preferred form of the invention means is provided for normally yieldingly urging the plug 18 into the opening 22 so that it tightly seats inthe opening and for effectively compressing the packing 41 and 47. A nut 50 is screw threaded onto the reduced stem 28 of the plug 18. A compression sleeve 5l is arranged between the nut 50 and the body 16. The sleeve 51 may be slidable on a cylindrical enlargement 52 at the base of the stem 28. The sleeve 51 is provided with an annular flange 54 extending into the groove 46 and engaging the packing 47. The ange 54 cornpletely closes the end of the groove 46. A radial shoulder is provided on the sleeve 51 to engage an end ofthe body 16 to limit movement of the vange 54 into the groove 46.

A helical spring 56 is arranged under compression between the sleeve 51 and the nut 50. In the preferred form of the invention an annular apron or lip 57 is provided on the nut 50 to inclose the spring 56. The lip 57 may freely engage over the sleeve 51. The spring 56 acts to urge the sleeve 51inwardly to retain the flange 54 in effective engagement with the packing 47 and acts to urge the plug 18 downwardly or inwardly in the opening 22. In practice the nut 50 may be adjusted on the stern 28 to provide for the desired or necessary action of the spring 56. In thedrawings the nut 50 is shown in engagement with the sleeve 51.

In the preferred construction the plug is reinforced so that the stem 28 is particularly strong and is not apt to fail upon turning of the plug or tightening of the nut 50. The plug is preferably in the nature of a casting and a bar of soft steel is arranged in the stem 28 to strengthen the stem. The bar 80 may be arranged in themould when the plug is poured, so that it is effectively bonded in the plug. The bar 80 may extend completely through the stern 28 and extend'into the portion 48.

It is believed that theoperation of the ow bean provided by this invention will be readily apparent from the foregoing detailed description.

During normal operation of the device the plug 18 is positioned as illustrated throughout the drawings Where the nipple 18 is in direct register with the fluid passage 17. The nut 50 may be adjusted on the stem 28 vto provide for the proper urging of the plug 18 into the opening 22 and for the proper compression of the packing 4l and 47. When it is desired to remove the nipple 19 for replacement the plug 18 is rotated to a position where the opening 31 is in register with the opening 23. The lug 35 acts to limit turning of the plug in either direction so that it may be operated to the position where the opening 3l is in register'with the opening 23. The plugs 24 and 25 may be removed and the nipple 19 driven out through the opening 23 by means of a suitable tool. When the plug 18' is in the position for removing the nipple 19 the passage of fluid through the device is positively prevented. Grease or other suitable uid may be supplied to the grooves 42 and 46 under pressure to actuate the packing. The flange 30 on the plug prevents uid that may leak from the device from squirting or iiying onto the operator. The lip 57 preventsuid that may leak past the sleeve 51 from discharging directly outward.
