Description

MULTI-PORT DIVERTER VALVE
FIELD OF THE INVENTION The present invention is directed to a manifold diverter valve for fluids, in general and specifically for flow lines from a plurality of oil wells.
BACKGROUND OF THE INVENTION
Traditionally, oil well testing is achieved by adopting the dual production and test manifold system with connecting pipework and shut-off valves for each oil well flow line. This enables each well to be isolated and diverted to the test manifold. Although this conventional system has proven functionality and reliability, it is costly; due to its large weight and size. These and other difficulties experienced with the prior art coating systems have been obviated by the present invention.
It is, therefore, a principal object of the present invention to provide a multi-port diverter valve which is simple, light and relatively inexpensive than prior art test manifold systems. A further object of the present invention is the provision of a multi-port diverter valve which substantially reduces the change in flow path direction to minimize erosion of parts due to fluid flow.
Another object of the present invention is the provision of a multi-port diverter valve which enables fluid to be diverted for testing from any one of a plurality of fluid flow lines disrupting fluid flow from the remaining flow lines to a main production line.
A still further object of the present invention is the provision of a multi-port diverter valve which enables fluid to be diverted to a test line test from any one of a plurality of flow lines without the need for shut off valves for each flow line when changing the test flow from one flow line to another flow line. With these and other objects in view, as will be apparent to those skilled in the art, the invention resides in the combination of parts set forth in the specification and covered by the claims appended hereto. BRIEF SUMMARY OF THE INVENTION
A diverter valve for fluids such as oil which includes a manifold housing containing a main chamber, an outlet port and a diverter port from the main chamber and a plurality of inlet flow channels. A diverter is located within the manifold housing has a diverter channel and is controlled by an actuator for selectively connecting the diverter channel to any one of the inlet flow channels which connecting the remaining flow channels to the main chamber.

DETAILED DESCRIPTION OF THE INVENTION
Referring to FIGS. 1-4, the multi-port diverter valve of the present invention includes a manifold housing, generally indicated by the reference numeral 10. The housing 10 comprises an inlet manifold housing portion 12, a diverter housing portion 14 connected to the inlet manifold housing portion 12 by bolts 15. A diverter 16 is located within the diverter housing portion 14 and an actuator 20 is located within the inlet manifold housing portion 12. The diverter housing portion 14 contains a main chamber 22 which is connected to a diverter port 24 and an outlet port 18.
The inlet manifold housing portion 12 contains a plurality of inlet flow channels 26. Each inlet flow channel 26 has an inlet opening 28 and an outlet opening 30. Each inlet opening 20 is connected to an inlet flow line 32. The inlet flow lines 32 are connected to the separate wells. A production flow line 34 is connected to the outlet port 18. A test flow line 36 is connected to the diverter port 24 and contains a valve 38.
The diverter 16 has a plurality of inlet ports 40 which are arranged in a circle about an axis of rotation 41. The diverter 16 also contains a diverter channel 42 which has an inner opening 44 and an outer opening 46. The diverter 16 has a cylindrical outer portion 48 which contains a portion of the diverter channel 42 and the outer opening 46 and is operatively connected to the diverter port 24. The cylindrical outer portion 48 is located in a sealing and guiding mechanism 50 which enables the outer portion 48 to move linearly along the axis 41 and to rotate about the axis 41. The inner end of the diverter 16 has a shaft 52 which is located in a bearing 55 and a sealing and guiding mechanism, generally indicated by the reference numeral 54, which enables the shaft 52 to move linearly along the axis 41 and to rotate about the axis 1. The sealing and guiding mechanisms 50 and 54 enable the diverter to be shifted linearly within the chamber 22 about the axis 41 and to rotate about the axis 41. The shaft 52 is connected to the actuator 20 which provides the linear and rotational movements selectively to the diverter 16. The actuator 20 enables the inner opening at the diverter to be selectively connected to any one of the outlet openings 30 while the inlet ports 40 are operatively connected to the remaining outlet openings 30. A first sealing element 56 is located in each of the outlet openings 30 for sealingly engaging a complimentary second sealing element, generally indicated by the reference numeral 58, located in each of the inlet ports 40 and the inner opening 44 of the diverter 16.
During operation of the multi-port diverter valve of the present invention, oil from a plurality of wells flows through the inlet flow lines 32 to the main chamber 22 and thereafter exits into the reduction flow line 34 through the outlet port 18. However, one of the inlet flow lines 32 is connected to the test line 36 through the diverter 16. When it is desired to test the production from a different inlet flow line 32, the actuator is energized to move the diverter 16 axially away from the diverter housing portion 14. This momentarily disconnects the inner opening 44 and the inlet ports 40 from the outlet openings 30. The diverter 16 is then rotated by the actuator 20 about the axis 41 so that the inner opening 44 is aligned with the outlet opening 30 which corresponds to the flow line 32 to be tested. The diverter 16 is moved axially toward the diverter housing portion 14 by the actuator 20 so that the first and second sealing elements 56 and 58 at the outlet openings 30 are brought into sealing engagement. Oil from all of the inlet flow lines 32, except the flow lines 32 just selected, enters the main chamber 22 and flows thereafter into the main production line 34.
Referring to FIG. 5, the first and second sealing elements 56 and 58 include a rugged energized tapered leg metal "T" seal 61. Referring to FIGS. 6 and 7, each of the sealing and bearing mechanisms uses a polymer multi seal stack 62 with a spring energized low pressure seal and stem scrapper ring
64 which provides protection from produced sand. One or more retaining rings 66 are also used. Sealing at the inner opening 44 of the diverter is achieved by energized tapered leg metal "T" seals 61 within the first sealing element 56. Mating seat inserts 68 are retained within the sealing element 58 for ease of maintenance. Sealing mechanism 54 includes a wear sleeve 70.
The required actuation motion for the diverter valve of the present invention is as follows:
1. Linear disengagement of diverter 2. Incremental rotation
3. Linear engagement of diverter The required motion of the diverter can be achieved by various combinations of rotational and linear actuation devices and power sources. The proposed remotely operated hydraulic actuator provides a compact positive indexing solution by using helical geared piston discs, solenoid valves and limit switches. Hydraulic pressure lifts the diverter 16 off the seals, pressure via an additional port will then compress and accurately rotate the helical geared piston discs and diverter to the next inlet port. The diverter 16 then linearly engages on the next port as the geared piston discs are expanded to their original position.
The diverter valve of the present invention can be adapted to suit specific actuator requirements with no detrimental effect on the primary functional features.
