進口先導膜片式電磁閥產品概述：

德國《LOCKE》洛克--進口先導膜片式電磁閥是指采用不銹鋼材質，先導膜片式結構的電磁閥。閥前后存在壓力差，大通徑選用先導式電磁閥。先導式電磁閥，通電時，依靠電磁力提起閥桿，導閥口打開，此時電磁閥上腔通過先導孔卸壓，在主閥芯周圍形成上低下高的壓差，在壓力差的作用下，流體壓力推動主閥芯向上移動將主閥口打開；斷電時，在彈簧力和主閥芯重力的作用下，閥桿復位，電磁閥上腔壓力升高，流體壓力推動主閥芯向下移動，主閥口關閉。

The imported pilot diaphragm type solenoid valve is made of stainless steel with pilot diaphragm structure. There is a pressure difference between the front and rear of the valve, and the pilot type solenoid valve is selected for the large diameter. When the pilot type solenoid valve is powered on, the valve rod is lifted by the electromagnetic force, and the pilot valve port is opened. At this time, the upper chamber of the solenoid valve releases the pressure through the pilot hole, forming a high differential pressure around the main valve core. Under the action of the pressure difference, the fluid pressure pushes the main valve core to move upward to open the main valve port; when the power is off, the valve rod is reset under the action of spring force and the gravity of the main valve core, and the upper chamber of the solenoid valve is opened When the pressure increases, the fluid pressure pushes the main valve core downward and the main valve port is closed.
