Valve Core Buffer Groove Structure for Stable Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional valve cores experience poor seal tightness due to direct water flow impact and unstable force on sealing elements, leading to deformation and displacement, which compromises sealing effectiveness over time.
Innovation Solution
A valve core design featuring a columnar body with crisscross connected water passage holes, a buffer groove, and a partitioning portion that separates the sealing block from direct water flow impact, using a connection hole with a smaller diameter to equalize water pressure and prevent seepage, combined with a guide portion for precise positioning and outward adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a valve flap or gasket is disposed on the valve core to seal the outlet or inlet of the valve body, then sealing effectiveness is improved, but the valve flap or gasket is subjected to large impact force from water flow, causing deformation and displacement
Solution Approach 1:
The patent introduces a buffer groove as an intermediary structure between the water flow and the sealing block. The buffer groove receives and absorbs the impact force from water flow, preventing direct transmission of large impact forces to the sealing block. This mediator structure protects the sealing element while maintaining sealing effectiveness.
Solution Approach 2:
The buffer groove is designed to cushion the water flow impact before it reaches the sealing block. By providing this cushioning structure in advance, the patent prevents the sealing block from being subjected to sudden large impact forces that would cause deformation or displacement, thereby maintaining its sealing capability.
2Reliability
If the assembly precision of the valve flap or gasket is improved to ensure stability, then sealing tightness is enhanced, but the valve flap or gasket wears down after long period of use, making assembly precision difficult to guarantee continuously
Solution Approach 1:
The patent changes the material parameter of the sealing block from rigid materials to elastic materials. This parameter change allows the sealing block to maintain its sealing function through elastic deformation rather than relying on precise assembly. The elastic material can continuously adapt to wear and maintain contact pressure, ensuring long-term sealing reliability without requiring high assembly precision.
Solution Approach 2:
The patent introduces dynamic adaptability to the sealing block through elastic materials. Instead of a static, rigid sealing element that requires precise initial assembly, the elastic sealing block can dynamically adjust its position and deformation to maintain sealing effectiveness even as wear occurs over time, thereby extending service life.
3Stability of the object's composition
If a rigid valve flap or gasket is used to avoid deformation defect, then structural stability is improved, but the material wears down after long period of use and loses expansive force, limiting sealing effect
Solution Approach 1:
The patent changes the material parameter from rigid to elastic, creating a sealing block that combines both structural stability and sealing reliability. The elastic material maintains its elastic properties over time, providing continuous expansive force to ensure sealing effectiveness while remaining structurally stable.
Solution Approach 2:
The patent uses composite material characteristics by combining the stability of a fixed structure with the adaptive properties of elastic materials. The sealing block is designed to utilize elastic deformation within a stable structural framework, achieving both structural stability and maintained sealing effect over extended service life.
4Productivity
If the inlet of the valve body has a large diameter to allow water flow, then flow capacity is improved, but the large contact area between water flow and gasket causes deformation and affects seal tightness
Solution Approach 1:
The patent segments the inlet structure by introducing a buffer groove that separates the large-diameter water flow passage from the sealing block. This segmentation allows the inlet to maintain large diameter for high flow capacity while the buffer groove protects the sealing block from direct exposure to the full water flow, preventing deformation and maintaining seal tightness.
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 enhances sealing stability and tightness by preventing direct water flow impact on the sealing block, maintaining consistent water pressure, and allowing the sealing block to adjust its position to ensure continuous seal integrity despite wear.
Implementation Method 1
the sealing block is made of elastic material, and the outer side of the sealing block is pressed tightly on the inner wall of the valve body
Implementation Method 2
the water pressure in the valve body acts on the valve flap or the gasket to increase the pressing force between the valve flap or the gasket and the valve body
