AI Technical Summary
In existing drain valve structures, the antifreeze valve and solenoid valve are separate components, which are cumbersome to connect, bulky, and prone to leakage.
Design an integrated drain valve structure, including a connecting seat, a solenoid valve assembly and a valve core assembly. The valve core assembly is movably disposed in the receiving cavity. The solenoid valve assembly is used to control fluid flow. The valve core assembly moves automatically under specific conditions to achieve opening and closing, reducing the number of sealing parts.
It enables automatic or manual control of the drain valve, simplifies the structure, reduces sealing parts, and solves the problems of complex structure and water leakage in the existing technology.
