寶碩直動(dòng)式電磁閥文檔,BUSCJOST直動(dòng)式電磁閥技術(shù)介紹
直動(dòng)式電磁閥，通電時(shí)，電磁線圈產(chǎn)生電磁力把關(guān)閉件從閥座上提起，
閥門打開(kāi)；斷電時(shí)，電磁力消失，彈簧把關(guān)閉件壓在閥座上，閥門關(guān)閉。
它是種直動(dòng)和導(dǎo)式相結(jié)合的原理，當(dāng)入口與出口沒(méi)有壓差時(shí)，
通電后，電磁力直接把導(dǎo)小閥和主閥關(guān)閉件依次向上提起，閥門打開(kāi)。
The valves of this series, including the connection size DN 25
(G 1), are according to Art. 3 § 3 of the Pressure Equipment Directive
(PED) 97/23/EG. This means interpretation and production are in
accordance to engineers practice wellknown in the member countries
當(dāng)入口與出口達(dá)到啟動(dòng)壓差時(shí)，通電后，電磁力導(dǎo)小閥，主閥下腔壓力上升，
上腔壓力下降，從而利用壓差把主閥向上推開(kāi)；斷電時(shí)，
導(dǎo)閥利用彈簧力或介質(zhì)壓力推動(dòng)關(guān)閉件，向下移動(dòng)，使閥門關(guān)閉。

Note to Electromagnetic Compatibility Guideline (EEC):
The valves shall be provided with an electrical circuit which ensures
the limits of the harmonised standards EN 61000-6-3 and
EN 61000-6-1 are observed, and hence the requirements of the
Electromagnetic Compatibility Guideline (2004/108/EG) satisfield.
特點(diǎn)：1.在真空、負(fù)壓、零壓時(shí)能正常工作，但通徑般不超過(guò)25mm。
2.在零壓差或真空、高壓時(shí)亦可動(dòng)作，但功率較大，要求必須水平安裝。

For valves > DN 25 (G 1) Art. 3 § (1) .4 applies.
The basic requirements of the Enclosure I of the PED must be fulfilled.
The CE-sign at the valve includes the PED. A certificate of conformity of
this directive will be available on request.
