Single valved bypass meter bar system
View Patent ↗A meter bar system and method can include: providing a body; and coupling a valve to the body, the valve configured to provide gas flow configurations based on a rotational position of the valve, the gas flow configurations including a normal gas flow configuration, a purge gas flow configuration, and a bypass gas flow configuration.
1 . A meter bar system comprising:
a body having an input connection port, an output connection port, a meter input connection port, and a meter output connection port, the body further including a safety shroud; and
a valve coupled to the body, the valve configured to provide gas flow configurations based on a rotational position of the valve, the valve includes a lockout hole for fixing the valve in the rotational position, the gas flow configurations including:
a normal gas flow configuration for allowing gas to flow from the input connection port through the valve and out of the meter input connection port and from the meter output connection port through the valve and through the output connection port,
a purge gas flow configuration for allowing the gas to flow from the input connection port through the valve and through the output connection port, and allowing the gas to flow through the valve and the meter input connection port, and
a bypass gas flow configuration for allowing the gas to flow from the input connection port through the valve and out of the output connection port.
2 . The system of claim 1 wherein: the valve includes an internal valve structure with a straight side opposite a curved side, the straight side and the curved side converge to form a narrow end.
3 . The system of claim 1 wherein: the valve includes an internal valve structure with a straight side opposite a curved side, the straight side and the curved side diverge to form a thick end.
4 . The system of claim 1 wherein: the valve includes an internal valve structure with seals on two opposing ends.
5 . The system of claim 1 wherein: the valve includes a valve handle for changing the rotational position of the valve.
6 . The system of claim 1 wherein: the safety shroud includes location indicators indicating the rotational position of the valve in the normal gas flow configuration, the purge gas flow configuration, and the bypass gas flow configuration.
7 . The system of claim 1 wherein: the safety shroud includes a lock out location for fixing the valve in the rotational position.
8 . The system of claim 1 wherein: the valve includes a handle configured to contact the safety shroud at a limit of the rotational position of the valve.
9 . A method of manufacturing a meter bar system comprising:
providing a body having an input connection port, an output connection port, a meter input connection port, and a meter output connection port, the body further including a safety shroud; and
coupling a valve to the body, the valve configured to provide gas flow configurations based on a rotational position of the valve, the valve includes a lockout hole for fixing the valve in the rotational position, the gas flow configurations including:
a normal gas flow configuration for allowing gas to flow from the input connection port through the valve and out of the meter input connection port and from the meter output connection port through the valve and through the output connection port,
a purge gas flow configuration for allowing the gas to flow from the input connection port through the valve and through the output connection port, and allowing the gas to flow through the valve and the meter input connection port, and
a bypass gas flow configuration for allowing the gas to flow from the input connection port through the valve and out of the output connection port.
10 . The method of claim 9 wherein: coupling the valve includes coupling the valve having an internal valve structure with a straight side opposite a curved side, the straight side and the curved side converge to form a narrow end.
11 . The method of claim 9 wherein: coupling the valve includes coupling the valve having an internal valve structure with a straight side opposite a curved side, the straight side and the curved side diverge to form a thick end.
12 . The method of claim 9 wherein: coupling the valve includes coupling the valve having an internal valve structure with seals on two opposing ends.
13 . The method of claim 9 wherein: coupling the valve includes coupling the valve having a valve handle for changing the rotational position of the valve.
14 . The method of claim 9 wherein: providing the body includes providing the body with the safety shroud having location indicators indicating the rotational position of the valve in the normal gas flow configuration, the purge gas flow configuration, and the bypass gas flow configuration.
15 . The method of claim 9 wherein: providing the body includes providing the body with the safety shroud having a lock out location for fixing the valve in the rotational position.
16 . The method of claim 9 wherein: coupling the valve includes coupling the valve having a handle configured to contact the safety shroud at a limit of the rotational position of the valve.
