进口信号反馈电磁阀 德国洛克信号反馈电磁阀

一、进口信号反馈电磁阀产品概述：

德国《LOCKE》洛克--进口信号反馈电磁阀，电磁阀里有密闭的腔，在不同位置开有通孔，每个孔都通向不同的油管，腔中间是阀，两面是两块电磁铁，哪面的磁铁线圈通电阀体就会被吸引到哪边，通过控制阀体的移动来档住或漏出不同的排油的孔，而进油孔是常开的，液压油就会进入不同的排油管，然后通过油的压力来推动油缸的活塞，活塞又带动活塞杆，活塞杆带动机械装置动。

1、 Overview of imported signal feedback solenoid valve products:

Locke - imported signal feedback solenoid valve. The solenoid valve has a closed cavity with through holes at different positions. Each hole leads to a different oil pipe. There is a valve in the middle of the cavity and two electromagnets on both sides. The valve body will be attracted to which side when the magnet coil is electrified. The movement of the valve body is controlled to block or leak different oil drain holes, and the oil inlet hole is normally open, The hydraulic oil will enter different oil discharge pipes, and then push the piston of the oil cylinder through the pressure of the oil. The piston drives the piston rod, and the piston rod drives the mechanical device.

三、进口信号反馈电磁阀工作原理：

常闭——当线圈通电时，先导阀芯吸合，先导孔打开，阀上腔卸压，活塞靠下腔介质压力推动，电磁阀打开。

当线圈断电时，先导阀芯靠弹簧复位，先导孔关闭，阀上腔由活塞节流孔增压和复位弹簧的推力，电磁阀关闭。

常开——当线圈通电时，先导阀芯靠弹簧复位，先导孔关闭，阀上腔由活塞节流孔增压和复位弹簧的推力，电磁阀关闭。

当线圈断电时，先导阀芯靠弹簧复位，先导孔打开，阀上腔卸压，活塞靠下腔介质压力推动，电磁阀打开。

信号反馈—— 当电磁阀打开时，信号公共线和开信号线接通； 当电磁阀关闭时，信号公共线和关信号线接通。

3、 Working principle of inlet signal feedback solenoid valve:

Normally closed - when the coil is energized, the pilot valve core is closed, the pilot hole is opened, the pressure in the upper chamber of the valve is relieved, the piston is pushed by the medium pressure in the lower chamber, and the solenoid valve is opened.

When the coil is powered off, the pilot valve core is reset by the spring, the pilot hole is closed, the upper chamber of the valve is pressurized by the piston orifice and the thrust of the reset spring, and the solenoid valve is closed.

Normally open - when the coil is energized, the pilot valve core is reset by the spring, the pilot hole is closed, the upper chamber of the valve is pressurized by the piston orifice and the thrust of the reset spring, and the solenoid valve is closed.

When the coil is powered off, the pilot valve core is reset by the spring, the pilot hole is opened, the pressure in the upper chamber of the valve is relieved, the piston is pushed by the medium pressure in the lower chamber, and the solenoid valve is opened.

Signal feedback: when the solenoid valve is opened, the signal common line and the open signal line are connected; When the solenoid valve is closed, the signal common line and the off signal line are connected.
