Saturation valve assembly for electric cables

A discard/vacuum tank subassembly, comprising:

• (a) a discard tank configured to receive fluid from a source;
• (b) a valve assembly, comprising:
• (i) a fluid column having a first open end and a second open end, the first open end in fluid communication with the discard tank and configured to receive fluid from the discard tank when fluid within the discard tank reaches a predetermined threshold;
• (ii) a fluid flow path defined between the first and second open ends of the fluid column;
• (iii) a saturation valve portion disposed within the fluid flow path, wherein the saturation valve portion is a first configuration when no fluid is flowing through the fluid flow path, and wherein the saturation valve portion transitions to a second configuration when fluid is flowing through the fluid flow path;
• and
• (c) a vacuum tank in fluid communication with the second open end of the fluid column.

A fluid injection assembly, comprising:

• (a) a cable having first and second ends;
• (b) a fluid feed tank in communication with the first end of the cable and configured to inject fluid into the cable;
• (c) a discard tank in communication with the second end of the cable and configured to receive fluid flushed from the cable;
• (d) a valve assembly, comprising:
• (i) a fluid column having a first open end and a second open end, the first open end in fluid communication with the discard tank and configured to receive fluid from the discard tank when fluid within the discard tank reaches a predetermined threshold;
• (ii) a fluid flow path defined between the first and second open ends of the fluid column;
• (iii) a saturation valve portion disposed within the fluid flow path, wherein the saturation valve portion is a first configuration when no fluid is flowing through the fluid flow path, and wherein the saturation valve portion transitions to a second configuration when fluid is flowing through the fluid flow path;
• and
• (e) a vacuum tank in fluid communication with the second open end of the fluid column.

A valve assembly configured to close off the flow of fluid within a fluid injection assembly, the valve assembly comprising:

• (a) a fluid column having a first open end and a second open end;
• (b) a fluid flow path defined between the first and second open ends of the fluid column;
• and
• (c) a saturation valve portion disposed within the fluid flow path, wherein the saturation valve portion is a first configuration when no fluid is flowing through the fluid flow path, and wherein the saturation valve portion transitions to a second configuration when fluid is flowing through the fluid flow path, wherein the fluid flowing through the fluid flow path is selected from the group consisting of phenylmethyldimethoxysilane, dimethyldimethoxysilane, trimethylmethoxysilane, dimethyldibutoxysilane, tolylethylmethyldimethoxysilane, dimethoxymethyl[2-(methylphenyl)ethyl]silane, cyanobutylmethyldimethoxysilane, 2-(4-methylphenethyl)methylbis(2-ethylhexoxy)silane, di(2-ethylhexoxy)methyl[2-(methylphenyl)ethyl]silane, 3-cyanobutylmethylbis(2-ethylhexoxy)silane, and acetephenone, and any combination thereof.

A valve assembly configured to close off the flow of fluid within a fluid injection assembly, the valve assembly comprising:

• (a) a fluid column having a first open end and a second open end;
• (b) a fluid flow path defined between the first and second open ends of the fluid column;
• and
• (c) a saturation valve portion disposed within the fluid flow path, wherein the saturation valve portion is a first configuration when no fluid is flowing through the fluid flow path, and wherein the saturation valve portion transitions to a second configuration when fluid is flowing through the fluid flow path, wherein the fluid flow path is further defined by a first transverse opening in fluid communication with the first open end of the fluid column, a second transverse opening in fluid communication with the second open end of the fluid column, and a sealed gap extending between the first and second transverse openings, wherein a column sleeve is disposed over the fluid column, wherein an internal diameter of the column sleeve is larger than an external diameter of the fluid column to define the sealed gap extending between the first and second transverse openings.

A valve assembly configured to close off the flow of fluid within a fluid injection assembly, the valve assembly comprising:

• (a) a fluid column having a first open end and a second open end;
• (b) a fluid flow path defined between the first and second open ends of the fluid column;
• and
• (c) a saturation valve portion disposed within the fluid flow path, wherein the saturation valve portion is a first configuration when no fluid is flowing through the fluid flow path, and wherein the saturation valve portion transitions to a second configuration when fluid is flowing through the fluid flow path, wherein a column sleeve is securable to the fluid column, the column sleeve having a longitudinal axial opening at a first end, a bore at a second end, and a fluid passageway extending between the longitudinal axial opening and the bore.
