→工作原理 Working principle

→手動控制：Manual control

1、當手柄箭頭與閥體流向箭頭平行時，電磁閥設(shè)定為電腦自動控制。

1,when the handle of the arrow and the valve body to the direction of the arrow,the solenoid valve set for the computer automatic control.

2、當手柄箭頭順時針旋轉(zhuǎn)90度時，電磁閥打開，此時電磁閥已轉(zhuǎn)為手動控制。按不銹鋼限位槽為準，逆時針旋轉(zhuǎn)90度時，電磁閥閉。

2,when the handle arrow clockwise rotation of 90 degrees,the solenoid valve is opened,this time the solenoid valve has been transferred to manual control.Press the stainless steel limit groove is accurate,the counter clockwise 90 degrees,the solenoid valve closes.

→自動控制：Auto-Control

1、當電磁閥線圈通電時，動鐵芯吸合，先導(dǎo)孔處于開啟狀態(tài)，使活塞上腔降壓，主活塞因介質(zhì)壓差開啟，介質(zhì)流通。

1,when the solenoid valve coil is energized,moving core pull,the pilot hole is in open state,so that the piston chamber pressure,the main piston medium pressure to open because of,media circulation.

2、當電磁閥線圈斷電時，動鐵芯依靠彈簧復(fù)位，先導(dǎo)孔關(guān)閉，使活塞上腔生涯，主活塞因介質(zhì)壓差關(guān)閉，介質(zhì)切斷。

2, when the solenoid valve coil power,the moving iron core depends on the spring,the pilot hole closed,so that the piston on the chamber,the main piston because of the media pressure difference,the media cut off.

→應(yīng)用范圍 Scope of appllcauon

蒸汽系統(tǒng)、高壓系統(tǒng)、低溫系統(tǒng)、供熱系統(tǒng)、灌裝系統(tǒng)、電廠設(shè)備、石化設(shè)備、管道自控工程等。

→注解 Note

流體中若含有雜質(zhì)，電磁閥進端必須安裝過濾器，二進一出的工作原理的電磁閥兩進口端壓力不相等時，需加止回閥。可安裝止回閥或訂制自帶止回功能的閥門。

if the fluid contains impurities,solenoid valve into the end must be installed in the filter,two into a working principle of the solenoid valve two inlet end pressure is not equal,the need to add check valve.Can be installed check valve or custom comes with a return function of the valve.
