Sliding Valve Plate Water Valve for Pool Disinfection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for controlling water inflow and outflow in above-ground pools are labor-intensive, prone to leakage, and inefficient in disinfection, as plugs are difficult to operate and disinfectants fail to diffuse evenly due to sinking or drifting.
Innovation Solution
A water valve system with a sliding valve plate and integrated chemical dispenser that allows for easy operation, prevents leakage, and ensures even disinfection by using a chemical dispenser connected to the valve body, allowing chemical solutions to be dispersed throughout the pool via water flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If plugs are used to block water inlet and outlet, then water leakage can be prevented, but operation difficulty increases and user effort is required
Solution Approach 1:
The valve plate is designed to be operable by users sitting in the pool without requiring them to reach or exert significant effort. The long handle and sliding mechanism allow users to easily control water flow while seated, making the system self-service friendly and eliminating the need for difficult plugging operations
Solution Approach 2:
The valve body is divided into detachable components (valve seat and valve housing) that can be assembled and disassembled without tools. This segmentation allows for easy maintenance and operation while maintaining reliable sealing through the valve plate mechanism
2Ease of operation
If plugs are used to block water inlet and outlet, then water flow can be controlled, but water leakage may occur if plugs are not firmly plugged
Solution Approach 1:
The valve plate with sealing edge is designed to provide reliable sealing before any potential leakage can occur. The detachable connection between valve seat and valve housing ensures proper alignment and sealing surfaces are prepared in advance, preventing leakage issues that would require corrective action
3Reliability
If disinfection tablets are put directly into water, then sterilization can be achieved, but dissolved disinfectants can only diffuse to small area near tablets
Solution Approach 1:
The chemical dispenser utilizes water flow dynamics to distribute disinfectants. Tablets are placed in the dispenser which is positioned in the water stream, allowing flowing water to continuously pick up dissolved disinfectant and transport it throughout the pool, expanding the disinfection area from local to global
Solution Approach 2:
The valve body serves multiple functions: it controls water flow and simultaneously houses the chemical dispenser for disinfectant distribution. This multi-functionality integrates the disinfection system with the existing water circulation infrastructure, ensuring wide distribution of disinfectants through the same water flow that serves the primary filtration function

AI summary
A water valve and a pool are provided. The water valve includes a valve body having a first channel; and a valve plate having a valve plate opening and configured to control opening or closing of the first channel by sliding; when the valve plate is in a first position, the valve plate opening is aligned with the first channel and water can flow through the first channel, the water valve is opened; when the valve plate is in a second position, the first channel is blocked by the valve plate, the water valve is closed. The pool includes a water inlet part connected with a pool wall and the water valve detachably connected with the water inlet part. The water valve is simple in operation, has good sealing performance and switch function of the water valve and disinfection function of the chemical dispenser, thereby improving the water valve's performance.
