Pool Cleaning Valve Control for Low-Hammer Zone Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional in-floor pool cleaning systems experience increased wear and tear on equipment and piping due to repeated shutting off and turning on of water pressure to different zones, leading to valve hammering and inefficiencies in cleaning cycles.
Innovation Solution
A pool control system with a controller valve and distribution valve that includes a hydro-valve and pausing arm, controlled by a microcontroller to intelligently manage water flow to multiple zones, allowing customizable sequences, durations, and cycles, reducing wear and tear by diverting water flow without shutting off the pump.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If water pressure is repeatedly shut off and turned on to different zones, then cleaning cycles can be completed across multiple zones, but equipment wear and valve hammering increase
Solution Approach 1:
The system pre-pressurizes the water supply line before activating cleaning zones. The controller valve opens the bypass valve to allow water to flow through and pressurize the supply line before directing water to cleaning zones, eliminating the need for repeated pump start-stop cycles and reducing equipment wear from water hammer effects
Solution Approach 2:
The controller valve acts as an intermediary between the pump and distribution valve, managing water flow independently. By using the controller valve to regulate water flow and the bypass valve to manage pressure, the system eliminates the need for repeated pump cycling, reducing mechanical wear on the pump and motor while maintaining cleaning effectiveness

Solution Approach 2:
The pump operates continuously throughout the cleaning cycle, maintaining constant water flow through the system. The controller valve and bypass valve work together to manage water distribution and pressure without interrupting the pump's operation, eliminating the harmful water hammer effects caused by repeated pump start-stop cycles

Function Achieved in This Case
The system reduces equipment wear, minimizes valve hammering, and enhances cleaning efficiency by intelligently controlling water distribution to multiple zones, optimizing cleaning cycles based on user input.
Implementation Method 1
a hydro-valve configured to move between an open position in which the water passes from the water inlet to the primary water outlet and a closed position in which the water passes from the water inlet to the bypass water outlet
Implementation Method 2
a pausing arm configured to move between a disengaged position in which the outlet port aperture is configured to align with a new outlet port of the plurality of outlet ports each time the hydro-valve moves from the open position to the closed position and an engaged position in which the pausing arm maintains a position of the outlet port aperture regardless of the position of the hydro-valve

AI summary
A pool control system with a controller valve, a distribution valve, and a microcontroller. The controller valve has a primary water outlet and a bypass water outlet. The controller valve is configured to move between an open configuration in which the water passes from a water inlet to the primary water outlet and a closed configuration in which the water passes from the water inlet to the bypass water outlet. The distribution valve has an inlet port fluidly coupled to the primary water outlet and a plurality of outlet ports with an outlet port aperture. The outlet port aperture is configured to align with a new outlet port each time the controller valve moves from the open configuration to the closed configuration. The microcontroller is configured to discharge water from the pool control system by controlling the controller valve to change the configuration between the open and closed configurations.
