1、引言移动滑阀所必须的力,可采用不同的驱动方式得到。其中,常用电磁铁直接驱动。由于电磁铁在一个给定的结构体积下,只能输出一定的力,因而,准确地了解在换向中所必须克服的反力是很重要的。这样,才能通过一些相应的措施,保证电磁阀的工作可靠性。图1为一种带有两个法兰式安装电磁铁三位四通换向阀。 1, Introduction The necessary force of moving the slide valve can be obtained by different driving methods. Among them, the commonly used electromagnet direct drive. Since the electromagnet can only output a certain amount of force for a given volume of structure, it is important to know accurately the reaction force that must be overcome in the commutation. In this way, through some corresponding measures to ensure the reliability of the solenoid valve. Figure 1 shows a three-position, four-way reversing valve with two flange mounted solenoids.
