AI Technical Summary
Technical Problem
Existing electromagnetic directional valves have complex structures and insufficient directional stability.
Method used
The main valve adopts a structural design including a valve body, valve core, valve seat and slider. The valve core is driven to rotate by differential pressure, which drives the slider to connect between adjacent valve seat ports. The structure is simplified and the sealing part fits against the inner wall of the valve cavity to ensure stability.
Benefits of technology
It simplifies the structure of the electromagnetic reversing valve and improves its reversing stability. It has good sealing performance and can stably switch the refrigerant flow direction under a small pressure difference.

Abstract
本申请涉及一种电磁换向阀，包括主阀，主阀包括阀体、阀芯、阀座和滑块，阀体设有第一阀腔部和第二阀腔部；第一阀腔部通过分隔部分隔形成第一腔室、第二腔室和第三腔室，第一腔室和第二腔室之间连通有第一通道，第一腔室和第三腔室之间连通有第二通道；阀芯包括轴部和密封部，阀芯位于第一腔室内，阀芯能够绕轴部转动，并带动密封部贴合于第一腔室的内壁转动至密封部封堵第一通道或第二通道；阀座设有至少三个与第二阀腔部连通的阀座口，滑块位于第二阀腔部内，滑块朝向阀座的一侧设有连通槽，滑块可在阀芯的带动下转动，使连通槽连通于相邻两个阀座口之间。该电磁换向阀结构简单，可保证密封部在较小的压差作用下，能够稳定地带动滑块转动。
