Switching of the refrigerant processed between two runners.Fig. 1 specifically is referred to, the figure shows a kind of overall structure of three-way magnetic valve
Schematic diagram.
As shown in figure 1, coil（Not shown in figure）During no power, spring 5 promotes core iron part 3 to pass through steel to bottom offset
Ball pushes down valve port, and upper valve port is closed；At the same time, core iron part 3 pushes down on steel ball part 8 by drive link 2, opens lower valve
Mouthful, now refrigerant fluid flows to outlet 7 from inlet tube 4 by lower valve port.During coil electricity, the core iron under electromagnetic force
Part 3 is offseted with end socket 6 and is bonded, and steel ball and the upper valve port of the lower end of core iron part 3 are disengaged, and upper valve port is opened；At the same time, it is driven
Bar 2 loses the motive force of core iron part 3, and 8 upward top pressure of steel ball part is blocked lower valve port by returning spring 9, and lower valve port is closed, this
