Abstract
A meter bypass adapter has a body having: a first port; a second port; a third port; and a fourth port. At least one valve element is held by the body and moveable between: a first position wherein a flowpath is open from the first port to the second port and a flowpath is open from the third port to the fourth port without a direct flowpath from the first port to the fourth port; and a second position wherein a flowpath extends from the first port to the fourth port bypassing the second port and the third port. A single rotary actuator is held by the body to rotate about an axis and, in turn, shift the least one valve element between the first position and the second position.
Claims11
A meter bypass adapter comprising:
- a body having:
- a first port;
- a second port;
- a third port;
- and
- a fourth port;
- and
- at least one valve element mounted in the body for a linear shift between:
- a first position wherein a flowpath is open from the first port to the second port and a flowpath is open from the third port to the fourth port without a direct flowpath from the first port to the fourth port;
- and
- a second position wherein a flowpath extends from the first port to the fourth port bypassing the second port and the third port;
- and
- a single rotary actuator held by the body to rotate about an axis and, in turn, shift the least one valve element between the first position and the second position,
- wherein
- the at least one valve element comprises a first valve element and a second valve element;
- the first valve element and the second valve element each have a toothed rack;
- and
- the actuator has a pinion engaged to the toothed rack of the first valve element and the second valve element.
A meter bypass adapter comprising:
- a body having:
- a first port;
- a second port;
- a third port;
- and
- a fourth port;
- a first valve element held by the body and moveable between a first position and a second position;
- a second valve element held by the body and moveable between a first position and a second position;
- and
- an actuator coupled to the first valve element and second valve element to synchronize movement of the first valve element and second valve element between their respective first position and second position,
- wherein:
- movement of the first valve element between its first position and its second position is linearly opposite movement of the second valve element between its first position and its second position;
- with the first valve element and second valve element in their respective first positions a flowpath is open from the first port to the second port and a flowpath is open from the third port to the fourth port;
- and
- with the first valve element and second valve element in their respective second positions, a flowpath is open from the first port to the fourth port bypassing the second port and third port.
