Diaphragm Valve Flow Rate Optimization via Annular Groove
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional diaphragm valves face challenges in increasing flow rate without increasing the dimensions of the body and suffer from variations in flow rates among manufactured products.
Innovation Solution
The diaphragm valve features a body with a seat receiving surface, a seat-holder receiving surface, and an annular groove on its bottom surface, allowing for increased flow rate and reduced variations by optimizing the flow path through the seat holder's through holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the diameters of the fluid channels and through holes are increased to increase the flow rate, then the flow rate is improved, but the dimension of the body increases
Solution Approach 1:
The invention applies local quality by creating a depression (local凹陷 region) in the bottom surface of the valve body, concentrating the flow path optimization in a specific localized area rather than increasing overall body dimensions. The annular groove and seat receiving surface are formed only in the necessary depression region, allowing flow rate enhancement without proportional increase in the entire body size.
Solution Approach 2:
The invention utilizes the vertical dimension by forming a depression opening upward from the bottom surface, creating a three-dimensional flow path structure. The annular groove and seat receiving surface are positioned at different vertical levels within the depression, optimizing flow in the vertical dimension rather than only in the horizontal plane, thereby increasing flow rate without increasing the horizontal footprint.
2Productivity
If the diameters of the fluid channels and through holes are increased to increase the flow rate, then the flow rate is improved, but the variation in flow rates among manufactured products increases
Solution Approach 1:
The invention changes the geometric parameters of the flow path by forming a depression with specific depth and contour, creating an annular groove with defined cross-sectional area, and forming a seat receiving surface at a specific position. These parameter changes optimize the flow characteristics and reduce variations among manufactured products by providing a more controlled and consistent flow path geometry.
Solution Approach 2:
The flow path is segmented into distinct functional regions: the depression region, the annular groove, and the seat receiving surface. This segmentation allows each region to be optimized independently for its specific function, with the annular groove controlling the flow path and the seat receiving surface ensuring proper seat positioning, thereby reducing flow rate variations among products.

AI summary
Provided is a diaphragm valve that is capable of increasing its flow rate and is capable of suppressing variation among the diaphragm valves in the flow rates. In a diaphragm valve 1, a fluid that has flown into the fluid inflow channel 2a enters a fluid outflow channel 2b via through holes 22a of a seat holder 5. On a bottom surface 13 of a depression 2c of a body 2, a seat receiving surface 13a that receives a seat 4 is flush with a seat-holder receiving surface 13b that receives a seat holder 5. In the bottom surface of the depression 2c of the body 2, an annular groove 14 facing through holes 22 of the seat holder 5 is formed.
