KEYED CAP FOR GAS OUTLET VALVE

摘要

A gas valve includes a gas valve body (10) having a first end (16) configured to be coupled to a gas connection and a second end (20). A keyed body (72, 86, 94, 106, 116, 130) is configured to receive the second end (20) of the gas valve body (10). The keyed body (72, 86, 94, 106, 116, 130) has a first keying mechanism (80, 90, 102, 112, 120, 136). The apparatus also includes a cap (70, 88, 96, 108, 118, 132) coupled to the keyed body (72, 86, 94, 106, 116, 130). The cap (70, 88, 96, 108, 118, 132) includes a second keying mechanism (82, 92, 104, 114, 128, 144) configured to mate with the first keying mechanism (80, 90, 102, 112, 120, 136) on the keyed body (72, 86, 94, 106, 116, 130).
