Removable Filter Valve Pipe Fitting for Better Sealing and Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pipe fittings with filters have limited filtration efficiency due to filter size constraints and require cumbersome removal processes, making them inefficient for fluid purification between connection pipes.
Innovation Solution
The design includes a body with a receiving orifice featuring guide slots and a filter valve with a filtration orifice, allowing for a larger filter size and easy removal/replacement, utilizing seal gaskets and fixing bolts for secure filtration and easy maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the filter size is increased to improve filtration efficiency, then filtration efficiency is improved, but the device complexity and installation difficulty increase due to space constraints in conventional pipe fittings
Solution Approach 1:
The pipe fitting is divided into separate modular components: a body, a filter valve with integrated filter, and seal gaskets. This segmentation allows the filter to be independently sized and replaced without replacing the entire fitting, thereby improving filtration efficiency while maintaining manageable device complexity.
Solution Approach 2:
The filter valve is designed to be inserted into and nested within the body of the pipe fitting. The filter valve includes a driven section that fits into the receiving orifice of the body, allowing a larger filter to be accommodated within the overall fitting structure without proportionally increasing external dimensions.
2Ease of repair
If the filter is made removable for maintenance, then ease of maintenance is improved, but the reliability and sealing performance may deteriorate due to potential leakage
Solution Approach 1:
The filter valve is designed as a removable component that can be extracted from the body for maintenance. The filter is integrated with the filter valve, allowing the entire filter assembly to be removed as one unit by unscrewing the filter valve from the body, thereby simplifying maintenance while maintaining sealing integrity during operation.
Solution Approach 2:
Seal gaskets are pre-installed on the filter valve before it is inserted into the body. This preliminary action ensures that the sealing surfaces are already prepared and protected, maintaining reliable sealing performance when the filter valve is installed, while still allowing for easy removal and reinstallation during maintenance.
3Reliability
If the filter is securely fixed to prevent leakage, then sealing performance is improved, but the ease of removal and replacement deteriorates
Solution Approach 1:
Seal gaskets are pre-installed on the filter valve before insertion into the body. This preliminary sealing preparation ensures reliable leakage prevention during operation, while the simple screw-on/screw-off connection allows for easy removal and replacement without requiring complex disassembly procedures.
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
Enhances filtration efficiency with a larger filter and simplifies filter replacement and maintenance by allowing easy access and secure fixation within the pipe fittings, ensuring effective fluid purification.
Implementation Method 1
The filter is accommodated in the filtration orifice of the driven section, such that fluid flows between the first connection pipe and the second connection pipe and is filtered by the filter
Implementation Method 2
The two seal gaskets are accommodated in a first peripheral groove and a second peripheral groove respectively

AI summary
Pipe fittings with a filter contain a body, a filter valve, and two seal gaskets. The body includes a first connection pipe and a second connection pipe, a receiving orifice, and at least one guide slot. The filter valve includes a driven section and an operation portion. The two seal gaskets are accommodated in the first peripheral groove and the second peripheral groove respectively. The driven section has a first peripheral groove, a second peripheral groove, and a filtration orifice defined between the first peripheral groove and the second peripheral groove and communicating with the driven section, and at least one fixing bolt mounted between the operation portion and the first peripheral groove and extending outward from the driven section. The at least one fixing bolt slides into the at least one guide slot respectively so that the filter valve is accommodated in the receiving orifice.
