Pipeline system with automatically closing port

A pipeline assembly, comprising:

• a hollow body having a first opening and a second opening;
• a valve port provided on the hollow body, wherein the valve port is fluidly coupled to the first opening;
• a valve port seat disposed in the valve port;
• a shutter;
• a spring, coupled to the shutter, configured to urge the shutter against the valve port seat to fluidly de-couple the second opening from the first opening;
• a valve plug disposed in the valve port, wherein the valve plug decouples the shutter from the valve port seat to fluidly couple the first opening and the second opening to one another;
• and
• a check valve disposed in the valve plug, wherein the check valve is configured to prevent a fluid flow in a direction from the second opening to the first opening.

A pipeline assembly, comprising:

• a hollow body having an interior space;
• an inlet opening and an outlet opening, each provided on the hollow body and each fluidly coupled to the body interior space;
• a valve port provided on the hollow body and fluidly coupled to the inlet opening;
• a valve port seat disposed in the valve port;
• a shutter;
• a spring, coupled to the shutter, configured to urge the shutter against the valve port seat;
• and
• a valve plug body disposed in the valve port,
• wherein the valve plug decouples the shutter from the valve port seat;
• and
• further comprising at least one of:
• a check valve disposed in the valve plug body between a first space and a second space defined in the valve plug body, wherein the check valve is configured to prevent a fluid flow between the second space and the first space when the check valve is in a closed configuration;
• or a filter disposed in the valve plug body between the first space and the second space, wherein the filter is configured to filter out unwanted particles in a fluid flow between the first and second spaces.

A pipeline assembly, comprising:

• a body having an interior space defined therein;
• an outlet opening, provided on the body, fluidly coupled to the body interior space;
• a valve port opening, provided on the body, fluidly coupled to the body interior space;
• a valve port seat disposed in the valve port opening;
• a shutter;
• a spring, coupled to the shutter, configured to urge the shutter against the valve port seat to fluidly de-couple the outlet opening from the valve port opening;
• and
• a valve plug positioned in the valve port opening to decouple the shutter from the valve port seat, wherein the valve plug further comprises a check valve configured to prevent a fluid flow in a direction from the outlet opening.

A pipeline assembly, comprising:

• a body having an interior space defined therein;
• an outlet opening, provided on the body, fluidly coupled to the body interior space;
• a valve port opening, provided on the body, fluidly coupled to the body interior space;
• a valve port seat disposed in the valve port opening;
• a shutter;
• a spring, coupled to the shutter, configured to urge the shutter against the valve port seat to fluidly de-couple the outlet opening from the valve port opening;
• a valve plug positioned in the valve port opening to decouple the shutter from the valve port seat,
• wherein the valve plug is configured to fluidly isolate the valve port opening from the body interior space, and
• wherein the valve plug further comprises:
• a valve plug body;
• and a check valve defining a first interior valve space and a second interior valve space in an interior of the valve plug body, the first interior valve space fluidly coupled to the body interior space, wherein the check valve, when in a closed configuration, prevents a fluid flow between the first and second interior valve spaces.
