Abstract:
1. A device for detraction and temporary storage of fluid from a flow line, comprising: a first connector, for engagement with a source of fluid; a second connector, for engagement with a flow line for carrying the fluid; a resizable chamber, coupled to the first and second connectors, for temporarily holding fluid from the flow line; a main body comprising at least four engagement elements and an opening for selectively allowing flow of fluid from the first connector into the resizable chamber; a first component comprising at least one engagement element, movable with respect to the main body, but not separable therefrom, and wherein the first connector forms part of the first component: a second component comprising at least one engagement element, movable with respect to the main body, but not separable therefrom, and wherein the second connector forms part of the second component: wherein: the engagement element of the first component engages with a first engagement element on the main body to maintain an open position for the valve; the engagement element of the first component engages with a second engagement element on the main body to maintain a closed position for the valve; the engagement element of the second component engages with a third engagement element on the main body to hold the device in the first position wherein the chamber has the first size; and the engagement element of the second component engages with a fourth engagement element on the main body to hold the device in the second position wherein the chamber has the second size larger than the first size; and wherein the device has at least two positions, the positions comprising: a first position, wherein the chamber is configured to have a first size, for allowing flow of fluid from the source of fluid into the flow line; and a second position, wherein the chamber is configured to have a second size larger than the first size, for causing fluid to be detracted from the flow line into the chamber.
