US Patent:

55798004, Dec 3, 1996

Filed:

Jul 5, 1994

Appl. No.:

8/270509

Inventors:

Daniel Walker - Spring TX

Assignee:

Keystone International Holdings Corp. - Houston TX

International Classification:

F16L 5518
F16K 3700

US Classification:

137 15

Abstract:

An improved rotary valve indicator apparatus (10) and method is disclosed that includes an electronics switch housing (15), filled with epoxy or other generally elastomeric material (29) to hermetically seal, thus environmentally seal, the switch housing (15). A pair of hermetically sealed reed switches (30, 32) are employed within the electronics switch housing (15) for indicating the open and closed position of the valve (17). A pair of corresponding magnets (26, 28) are mounted within a separate magnet holder (16) that is mounted to a rotatable member (20) of a rotary valve actuator (13). Light emitting diodes (42, 44) radiate from a side portion (57) of the electronics switch housing (15) and are connected in a manner whereby they indicate not only that the respective switch (30, 32) is closed but also that it is conducting electricity. Additional electronics switch housings (15A)are stacked upon each other and additional magnet holder housings (16A) are stacked upon each other to provide for multiple circuits that may be operated at differing voltages or types of power. The electronics switch circuit (14) operates with a wide range of power or signals including alternating and direct current.

Abstract:

An adjustable magnet carrier 100 for a rotary valve indicator apparatus 10 is disclosed. The adjustable magnet carrier 100 includes an extension member 117 having an extension member body 118, an extension member body top 119, and an extension body base 121. Upper and lower magnet carriers 144, 146 selectively rotate about extension member 117 to adjust the stand-off between the magnets 102, 104 and the magnetically responsive switches 30, 32. The magnetically responsive switches are hermetically sealed within a separate electronics switch housing 15. Light-emitting diodes 42, 44 radiate from electronics switch housing 15 in response to switches 30, 32. Drive shafts 124, 128 rotate the magnet carriers 144, 146. The outer surfaces of the upper and lower magnet carriers 144, 146, the ends of drive shafts 124, 128, and the light-emitting diodes 42, 44 are color-coded to correspond to each other and to the open and closed positions of rotary valve element 19.
