Abstract
A manifold that allows replaceable pressure relief components to be installed and replaced without requiring a system shut down. The manifold allows two pressure relief valves to be installed in separate pressure relief ports. The manifold also includes a valve switch that isolates each valve independently, while allowing the system to remain in operation. For example, in a first position, the manifold directs fluid flow to a first pressure relief valve, while a second pressure relief valve is isolated.
Claims20
A manifold, comprising:
- a manifold body having an inlet port and first and second pressure relief valve ports, wherein the first and second pressure relief valve ports are adapted to receive respective first and second pressure relief valves;
- and
- a switch valve coupled to the manifold body and having a valve head linearly movable between first and second positions, wherein when the valve head is in the first position, the valve head is disposed proximal to the second pressure relief port and fluid communication is allowed between the inlet port and the first pressure relief valve port, and when the valve head is in the second position, the valve head is disposed away from the second pressure relief port and fluid communication is allowed between the inlet port and the second pressure relief valve port.
A manifold, comprising:
- a manifold body having an inlet port and first and second pressure relief valve ports;
- and
- a valve coupled to the manifold body and having a valve head linearly movable between first and second positions, wherein when the valve head is in the first position, the valve head is disposed proximal to the second pressure relief port and fluid communication is closed between the inlet port and the second pressure relief valve port, and when the valve head is in the second position, the valve head is disposed away from the second pressure relief port and fluid communication is closed between the inlet port and the first pressure relief valve port.
A manifold and valve system, comprising:
- a manifold body having an inlet port and first and second pressure relief valve ports;
- a first pressure relief valve disposed in the first pressure relief port;
- a second pressure relief valve disposed in the second pressure relief port;
- and
- a valve coupled to the manifold body and having a valve head linearly movable between first and second positions, wherein when the valve head is in the first position, the valve head is disposed proximal to the second pressure relief port and fluid communication is closed between the inlet port and the second pressure relief valve port, and when the valve head is in the second position, the valve head is disposed away from the second pressure relief port and fluid communication is closed between the inlet port and the first pressure relief valve port.
