SYNCHRONOUS SWITCH VALVE CORE HAVING VOLTAGE REGULATING FUNCTION

Title:

SYNCHRONOUS SWITCH VALVE CORE HAVING VOLTAGE REGULATING FUNCTION

Document Type and Number:

WIPO Patent Application WO/2021/139541

Kind Code:

A1

Abstract:

A synchronous switch valve core having a voltage regulating 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 buildup 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 waters, 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.
