Steam Trap Manifold Assembly With Double Isolation and Bleed Valves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Steam systems face inefficiencies due to condensate accumulation, non-condensable gases, dirt, scale, and metal particles, which hinder heat transfer and require effective isolation and maintenance strategies to prevent steam leaks and optimize operation.
Innovation Solution
A steam trap and valve assembly station with a manifold design that includes double isolation valves, bleed valves, and a compact structure to manage steam and condensate flow, allowing for easy maintenance and reduced steam leaks, featuring a single valve stem piston assembly for controlling multiple fluid passages and ports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple isolation valves are installed upstream and downstream of the steam trap, then the reliability of steam trap isolation is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple isolation valves (first upstream isolation valve and second downstream isolation valve) into a single integrated valve assembly that shares common components such as the valve body, actuation mechanism, and flow path structure. This merging approach maintains the functional separation of upstream and downstream isolation while reducing overall system complexity and component count.
Solution Approach 2:
The valve assembly is designed with universal components that serve multiple functions - the same valve body and actuation system handle both upstream and downstream isolation operations. The standardized design allows a single assembly configuration to perform multiple isolation functions, reducing the need for separate dedicated components for each isolation point.
2Area of stationary object
If a compact manifold design is used, then the space requirement is reduced, but the ease of operation for maintenance decreases
Solution Approach 1:
The valve assemblies and steam trap are arranged in a nested or closely integrated configuration within the manifold body, where components are positioned to maximize space utilization. The compact layout places the upstream and downstream isolation valves in close proximity to the steam trap, creating a space-efficient assembly that maintains functional accessibility through proper structural design.
3Reliability
If double isolation valves are installed, then steam leak prevention is improved, but the loss of time for operation increases
Solution Approach 1:
The valve assembly is pre-configured with both upstream and downstream isolation valves in a ready-to-operate state, allowing for rapid sequential closure in case of steam leaks. The pre-positioned design enables operators to quickly isolate the steam trap from both directions without requiring complex positioning or adjustment, reducing the time penalty associated with double isolation operations.

AI summary
A manifold for a steam system is provided with a body forming a first chamber extending between an inlet and an outlet along a first axis and a second chamber extending from a face of the body along a second axis to intersect the first chamber. A first piston valve sub-assembly is disposed in the second chamber to enable and disable steam communication between the second chamber and a first port. A second piston valve sub-assembly is disposed in the second chamber to enable and disable steam communication between the second chamber and a second port. A handle is mounted for rotation relative to the face. A valve stem is connected to the handle and mounted for translation within the second chamber in response to rotation of the handle between four positions to individually activate and deactivate the first piston valve sub-assembly and the second piston valve sub-assembly.
