Synchronous Valve Core with Integrated Pressure Balancing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing valve systems require additional pressure balance modules and one-way check valves, which are prone to blockages, flow resistance, and short service life, complicating the system and increasing installation costs.
Innovation Solution
A synchronous switch valve core with a flow regulating module and balancing hydraulic module that integrates pressure balancing and flow control, eliminating the need for a separate check valve by allowing water to enter the pressure balancing module only after passing through the flow regulating module, thus preventing high-temperature immersion and lime scale buildup, and optimizing pressure differences between cold and hot water inlets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stress or pressure
If additional pressure balance modules are arranged to balance pressure, then pressure balancing is achieved, but the system complexity and installation cost increase
Solution Approach 1:
The patent integrates the pressure balancing function directly into the valve core structure. The valve core itself, through its synchronous switching mechanism and internal passage design, balances the pressure between cold and hot water passages, eliminating the need for separate pressure balance modules
Solution Approach 2:
The valve core is designed to perform multiple functions simultaneously: flow regulation, synchronous switching, and pressure balancing. This multi-functional design eliminates the need for additional dedicated pressure balance modules, simplifying the overall system
2Ease of operation
If the valve core is directly exposed to high-temperature water, then flow control is achieved, but the valve core is subject to high-temperature immersion, lime scale buildup, and reduced service life
Solution Approach 1:
The patent implements preliminary flow regulation before water enters the valve core's internal passages. The flow regulating module is positioned upstream to control and cool the water before it reaches the valve core, preventing high-temperature damage and lime scale accumulation
Solution Approach 2:
The flow regulating module acts as an intermediary between the incoming high-temperature water and the valve core. It pre-cools and regulates the water flow before it contacts the valve core, protecting the valve core from thermal damage while maintaining flow control functionality
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 extends the service life of the valve core, simplifies the valve body structure, reduces installation costs, and achieves balanced pressure differences, transforming the valve from a single flow regulator to a synchronized switch capable of pressure balancing, thereby eliminating the need for a separate balancing module.
Implementation Method 1
a balancing hydraulic module... to balance pressure in the channel under the action of the pressure balance module
Implementation Method 2
the pressure difference of the cold and hot water inletting through the traditional valve core is 3:1 after testing, and the pressure difference of the cold and hot water inletting can reach 20:1 after the valve core of the invention is adjusted in pressure

AI summary
A synchronous switch valve core with a voltage stabilizing function, comprising: a valve core housing (1), a valve core base (2), a flow regulating module, and a balancing hydraulic module. The flow regulating module is capable of cutting off a cold/hot water path before water enters a pressure balancing module, thus preventing high-temperature water from immersing the valve core, preventing the building of lime scale, protecting the valve core, and extending the service life; moreover, water flow can enter the pressure balancing module only after flowing through the flow regulating module, thus preventing the channeling of hot and cold, and obviating the need to install a check valve at a water intake elbow. By means of an optimized design with respect to the parts of the synchronous switch valve core, the synchronous valve core is transformed from a switch capable only of regulating flow into a switch not only capable of regulating flow but also capable of synchronized switching, and also capable of balancing the pressures within two channels, thus transforming a product equipped with the vale core from a complex channel into a simple channel, and obviating the need for separately providing a balancing module part; a valve body is structurally simple, has a shortened water path, and is inexpensive.
