結(jié)構(gòu)原理             丹富斯電磁閥/電磁閥作用
本閥通徑15～100為膜片式為二次開閥的先導(dǎo)式電磁閥，通徑125～300為三次開閥的先導(dǎo)式電磁閥，其結(jié)構(gòu)主要由副閥和主閥組成。根據(jù)斷電時所處開關(guān)狀態(tài)的不同，可分為常閉電磁閥和常開電磁閥。常閉電磁閥，常位時，活動鐵芯封住副閥口，閥腔內(nèi)壓力平衡，副閥、主閥口封閉。當(dāng)線圈通電，產(chǎn)生電磁力：將活動鐵芯吸上，副閥打開，主閥腔內(nèi)的介質(zhì)自導(dǎo)閥門外世，以致主閥閥杯上下產(chǎn)生壓力差，膜片或閥杯被迅速托起主閥口開啟，閥呈通路狀態(tài)。
當(dāng)線圈斷電，磁場消失，活動鐵芯復(fù)位，封閉副閥口，繼而副閥和主閥閥杯內(nèi)壓力上升，主閥閥杯壓向閥座，閥又呈關(guān)閉狀態(tài)。
常開電磁閥，當(dāng)線圈通電時，產(chǎn)生磁力，銜鐵在磁力作用下下移，推動副閥閥杯下移，副閥關(guān)閉，隨著主閥閥杯上下壓差趨向相等，主閥閥杯由自重壓向密封面，閥門關(guān)閉。當(dāng)線圈斷電后，磁力為零，銜鐵祁副閥閥杯由于彈簧作用上升，副閥打開，主閥閥杯內(nèi)介質(zhì)經(jīng)副閥流走，壓力下降，當(dāng)壓力降到一定值后，主閥閥杯由上下壓差作用向上升起，主閥打開，閥門開啟。

Structure principle 
This valve size 15 ~ 100 for diaphragm for secondary open valve guiding type solenoid valve, size of 125 ~ 300 for three open valve guiding type solenoid valve and its structure is mainly composed of pair of valve and main valve. Depending on the power of switch state, can be divided into the normally closed solenoid valve solenoid valve and it always open. Normally closed electromagnetic valves, and often, activity core sealed vice valve mouth, cavity pressure balance, the deputy valve, main valve closed. Electricity, when the winding electromagnetic force: the core activity on the absorption, vice valve is opened, the main valve cavity medium homing valve outside the world, so that the main valve cup of fluctuation pressure difference, diaphragm valve or cup was quickly in order to the main valve mouth open, valve distribution state. 
Disappear, when the coil power, magnetic activity core reset, the deputy valve closed mouth, then vice valve and pressure rise within the main valve cup, the main valve cup pressure to the valve seat, valve is closed. 
Normally open solenoid valve, when the coil electricity, magnetic, armature down, under the action of a magnetic drive vice valve cup down, the deputy valve closed, as the main valve cup of fluctuation pressure differential approach parity, the main valve cup by the pressure to the sealing surface, the valve closed. After the power coil, magnetic force is zero, armature qi vice valve cup due to the increasing spring action, the deputy valve is opened, the main valve cup in the medium run by the deputy valve, pressure drop, when pressure is below a certain value, the main valve cup by the pressure differential action rises up and down, open the main valve, the valve opens.
