Y-Shaped Pipeline Strainer With Reduced Angle and Dome Recess
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Y-shaped pipeline strainers experience pressure drops due to the obstruction caused by debris collection in the straining element, and they require complex flange systems for maintenance, which are prone to leaks and complicate the insertion and removal of the straining element.
Innovation Solution
A pipeline strainer design with a reduced angle between the straining element and the body, eliminating the bottom flange and optimizing the debris collection chamber's position to increase the straining element's presence in the fluid flow path, featuring a dome-shaped recess for easier insertion and a removable cover plate for simplified maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a large opening with flange and end cap is used to insert the straining element, then the straining element can be inserted, but the device complexity increases and reliability decreases due to potential leak points
Solution Approach 1:
The patent removes the flange and end cap components from the debris collection chamber design. The straining element is inserted through the outlet end of the body directly, eliminating the need for the complex flange system that was previously required to access and maintain the straining element.
Solution Approach 2:
The straining element is designed as a separable component that can be independently inserted and removed through the outlet end, allowing maintenance without disassembling the entire strainer body or dealing with flange connections.
2Ease of operation
If the straining element is inserted through a large opening with flange, then insertion is possible, but the amount of straining element in the flow path is reduced due to flange interference
Solution Approach 1:
The flange that interfered with the flow path is completely removed from the design. The straining element can now extend fully through the outlet end without any flange obstruction, maximizing its presence in the fluid flow path.
3Adaptability or versatility
If conventional Y-shaped design with oblique debris collection chamber is used, then vertical piping compatibility is achieved, but pressure drop increases due to obstruction from debris collection
Solution Approach 1:
Instead of having the debris collection chamber oblique to the flow path (conventional design), the patent inverts the approach by making the straining element oblique to the flow path while keeping the debris collection chamber aligned with the flow direction. This allows debris to be collected efficiently without creating excessive pressure drop.
Solution Approach 2:
The patent changes the orientation from the conventional approach by positioning the straining element at an oblique angle (between 10-45 degrees) relative to the longitudinal axis of the body, rather than having the debris collection chamber oblique. This dimensional change optimizes both flow characteristics and debris collection.
4Ease of repair
If complex flange system is used for maintenance, then straining element can be accessed, but ease of repair worsens due to leak points and complexity
Solution Approach 1:
The flange system is completely extracted from the design. The straining element is accessed by simply removing the strainer body from the pipeline, eliminating all flange-related leak points and simplifying the repair process.

AI summary
A pipeline strainer having a body with a straining element therein. The body has a Y-shape and defines a cavity to receive the straining element. The cavity may be defined in part by a recess that comprises a surface which may be used to guide the straining element as it is inserted into the cavity. The recess may form a dome. The recess, when viewed cross sectionally, may have a linear segment and a curvilinear segment. A rounded protrusion may be created on an outer surface of the body as a result of the recess.
