Water Inlet Valve Filter Dividing Mechanism for Blockage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional inlet valves are prone to blockages due to poor water quality, which prevents backpressure formation and requires professional disassembly for cleaning, making them difficult for ordinary operation.
Innovation Solution
A stain-resistant and easy-to-clean inlet valve design featuring a filtering dividing mechanism with a filter component and inlet divider, allowing for complete filtration and easy assembly/disassembly, eliminating the need for a valve spool hole and incorporating a decompression hole and float mechanism for effective water control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional inlet valve with a valve spool and through hole is used, then the structure is simple, but the groove is easily blocked by dirt in poor water quality, preventing backpressure formation and water stop function
Solution Approach 1:
The inlet valve is divided into separate functional modules: a filter component that can be independently removed and cleaned, and a valve body with the water stop mechanism. The filter component includes a filter screen and inlet divider that can be detached without disassembling the entire valve or water pipes, allowing easy maintenance while protecting the valve stop function from blockage.
Solution Approach 2:
A filter component is installed upstream of the valve spool to pre-filter the water before it reaches the critical groove and valve stop padding. This preliminary filtration action prevents dirt from reaching and blocking the valve stop mechanism, ensuring reliable operation even in poor water quality conditions.
2Ease of operation
If the valve spool needs to be cleaned, then professional disassembly is required, but this makes it difficult for ordinary operation and maintenance
Solution Approach 1:
The filter component is designed as a separate, independently removable module from the valve body. It can be detached by simply unscrewing the filter component from the inlet passage, without needing to disassemble the valve body, water pipes, or internal valve mechanisms. This segmentation enables ordinary users to perform maintenance easily.
Solution Approach 2:
The filter component is extracted as a separate serviceable element that can be removed and cleaned independently. The design allows the filter screen and inlet divider to be taken out for cleaning without affecting the valve stop mechanism or requiring professional disassembly, making maintenance accessible to ordinary users.
3Reliability
If the filter component totally covers the inlet of the inlet passage, then filtration is complete, but the insert opening needs to be covered to prevent the filtering dividing mechanism from separating
Solution Approach 1:
The insert opening cover is nested within the filter component structure itself. The cover is integrated into the filter component assembly, forming a unified structure that combines filtration and sealing functions. This nested design eliminates the need for separate covering mechanisms while maintaining both filtration effectiveness and preventing unintended separation.
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 ensures cleaner water reaches the water stop valve, preventing blockages and allowing for quick maintenance without disassembling the water pipe, extending the valve's operational life and simplifying cleaning processes.
Implementation Method 1
water of the inlet passage is filtered when flowing through the filter component
Implementation Method 2
when water rises to the preset height, the float drives the plug to close the decompression hole
Implementation Method 3
the water pressure in the water chamber pushes the water stop padding to close the outlet

AI summary
A water inlet valve providing stain resistance, easy cleaning, and quick disassembly includes an inlet passage having an insert opening disposed at an upper end of the water inlet valve; an inlet divider; a filter component connected to the inlet divider to form a filtering dividing mechanism, and a water stop valve in communication with the water inlet valve that that controls the water inlet valve to stop water flow. The filter component and the inlet divider are disposed between the inlet passage an outlet of the inlet valve, water flowing through the inlet passage is filtered and is divided into two waterways by the inlet divider including a main waterway that flows to the outlet for inletting and a sub-waterway that flows to the water stop valve, and the filtering dividing mechanism is inserted into the inlet passage through the insert opening and is disassembled from the insert opening.
