Pleated Suction Strainer Venting Without Check Valve Bulk
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suction strainers face challenges in compact design due to the need for a check valve structure that increases in size, making it difficult to efficiently remove air bubbles.
Innovation Solution
A suction strainer with a tubular filtration section and an upper plate featuring an air vent hole, where a moving member is used to open and close the air vent hole, allowing for a compact and simple configuration to remove air bubbles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a check valve structure is provided on the first lid member, then air bubbles can be removed, but the device size increases
Solution Approach 1:
The invention extracts the air venting function from the traditional check valve structure and implements it separately through an air vent hole in the upper plate combined with a float mechanism. This separation allows the main strainer body to remain compact while adding a dedicated, space-efficient air removal system.
Solution Approach 2:
The float mechanism is nested within the strainer assembly, with the float moving within the space created by the tubular filtration section and upper plate. The air vent hole is integrated into the upper plate structure itself, nesting multiple functions within a compact arrangement.
2Object-affected harmful factors
If a traditional check valve is used, then air venting function is achieved, but the structure becomes complex
Solution Approach 1:
The invention extracts the air venting function from the traditional check valve structure and implements it separately through an air vent hole in the upper plate combined with a float mechanism. This separation allows the main strainer body to remain compact while adding a dedicated, space-efficient air removal system.
Solution Approach 2:
The invention changes the operational parameter of the air venting mechanism from a pressure-based check valve to a buoyancy-based float system. This parameter change simplifies the structure by eliminating complex valve seating and spring mechanisms, relying instead on the simple rise and fall of the float with air bubble accumulation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively removes air bubbles using a compact and simple air vent structure, ensuring efficient operation while maintaining a downsized moving member and air vent portion configuration.
Implementation Method 1
The moving member is provided to be movable between a position of closing the air vent hole and a position of opening the air vent hole. Thus, air bubbles are removable with the use of an air vent structure
Implementation Method 2
The tubular filtration section is formed by bending a thin plate in a pleat shape

AI summary
Air bubbles are removable with the use of an air vent structure having a compact and simple configuration. An air vent hole is formed in an upper plate that covers an entire upper end surface of a filtration section having a substantially tubular shape formed by bending a thin plate in a pleat shape. A moving member is provided to be movable between a position of closing the air vent hole and a position of opening the air vent hole.
