美国MAC四通电磁阀,电磁阀材质说明
四通阀,液压阀术语,是具有四个油口的控制阀。
四通阀是制冷设备中*的部件,其工作原理是,当电磁阀线圈处于断电状态,
So that the exhaust pipe connected with the outdoor machine, the other two connected to form a refrigeration cycle.
It is not difficult to find out by the valve structure. When the main spool is in the middle position,
As shown below, e, s, c three take over each other ventilation, resulting in intermediate flow,
At this point, the compressor within the high-pressure pipe refrigerant can flow directly back to the low-pressure pipe

使排气管与室外机接管相通,另两根接管相通,形成制冷循环。
由阀结构不难发现,当主滑阀处于中间位置状态时,
如下图所示,e、s、c三条接管相互通气,产生中间流量,
此时,压缩机内高压管内的冷媒可以直接流回低压管。
设计中间流量的目的是当主滑阀处在中间位置时,能起到卸压的作用,使系统免受高压破坏。
先导滑阀在右侧压缩弹簧驱动下左移,高压气体进入毛细管后进入右端活塞腔,
另一方面,左端活塞腔的气体排出,由于活塞两端存在压差,活塞及主滑阀左移,
Four-way valve, hydraulic valve terminology, is a control valve with four ports.
Four-way valve is an indispensable part of the refrigeration equipment,
its working principle is that when the solenoid valve coil is in power state,
Pilot slide valve in the right side of the compression spring drive left,
当电磁阀线圈处于通电状态,先导滑阀在电磁线圈产生的磁力作用下克服压缩弹簧的张力而右移,
高压气体进入毛细管后进入左端活塞腔,另一方面,右端活塞腔的气体排出,
由于活塞两端存在压差,活塞及主滑阀右移,
使排气管与室内机接管相通,另两根接管相通,形成制热循环
high pressure gas into the capillary into the right after the piston chamber,
On the other hand, the left end of the piston chamber gas discharge,
due to the existence of pressure at both ends of the piston, the piston and the main slide valve left,
