High-Flow Valve Seat Structure for Higher Water Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing water control valve structures face limitations in increasing water flow rate due to circular cross-section areas of flow channels, which restricts the cross-section area of the valve seat, making it difficult to enhance flow velocity without compromising structural strength or service life.
Innovation Solution
A high flow valve seat design with a main body featuring a circumferential part and through holes connected to flow channels, which enlarge the cross-section area by forming a waterway and flow channels with specific wall surfaces, allowing for increased water flow to the valve core structure.

Engineering Contradiction Analysis
1Productivity
If the cross-section area of the flow channel is enlarged to increase flow rate, then the flow rate increases, but the structural strength and service life are compromised
Solution Approach 1:
The patent transitions from a traditional 2D circular cross-section flow channel to a 3D multi-level flow channel structure with through-holes extending in multiple directions. This dimensional change allows the flow channel to occupy additional spatial volume without increasing the outer diameter of the valve seat, thereby enlarging the effective flow area while maintaining structural integrity.
Solution Approach 2:
The patent implements nested through-holes within the flow channel structure, where smaller circular through-holes are positioned within or adjacent to the main flow channel path. This nesting arrangement maximizes the use of available space within the valve seat, creating multiple flow paths that collectively increase the total flow rate without requiring a larger overall valve seat diameter.
2Ease of manufacture
If multiple circular water outlets are formed at the abutting end, then connection convenience is improved, but the cross-section area of the flow channel is confined
Solution Approach 1:
The patent adds a third dimension to the flow channel configuration by creating through-holes that extend radially and axially within the valve seat body. This multi-dimensional arrangement allows water to reach multiple outlets through interconnected 3D pathways, effectively increasing the total flow capacity without being constrained by the traditional 2D circular outlet layout at the abutting end.
Solution Approach 2:
The patent divides the flow channel into multiple segmented pathways, with each through-hole representing a distinct flow segment. These segmented channels are interconnected to form a network that distributes water to multiple outlets, allowing the system to achieve high flow rates while maintaining the circular outlet geometry for connection convenience.

AI summary
Disclosed is a high flow valve seat for a water control valve, including a main body, wherein the main body has one end and a circumferential part. The main body forms a waterway and several flow channels which straight extend from the end into the main body respectively. The main body forms several through holes connected to the flow channels respectively. The flow channel is formed of a first wall surface, a second wall surface and a third wall surface. The first wall surface is laterally adjacent to the circumferential part. The second wall surface and the third wall surface abut on both sides of the first wall surface respectively, and the second wall surface and the third wall surface extend away from the circumferential part respectively, so as to enlarge the cross-section area of the flow channel and to increase the flow of water to the valve core structure.
