德國GSR是我們公司的主營產(chǎn)品之一,我公司還德國500個品牌,歐州300多個品牌,美國200多個品牌貨源好,貨期短,保證原廠采購。
原理:通電時,電磁力把先導(dǎo)孔打開,上腔室壓力迅速下降,在關(guān) 閉件周圍形成上低下高的壓差,流體壓力推動關(guān)閉件向上移動,閥門打開;斷電時,彈簧力把先導(dǎo)孔關(guān)閉,入口壓力通過旁通孔迅速腔室在關(guān)閥件周圍形成下低上高的壓差,流體壓力推動關(guān)閉件向下移動,關(guān)閉閥門。
GSR先導(dǎo)閥是一種先導(dǎo)閥與主閥兩者間相互的閥體當(dāng)電磁閥線圈通電,動鐵芯與靜鐵芯吸合使導(dǎo)閥孔開放,閥芯背腔的壓力通過導(dǎo)閥孔流向出口,此時閥芯背腔的壓力低于進(jìn)口壓力,利用壓差使閥芯脫離主閥口,介質(zhì)從進(jìn)口流向出口。當(dāng)線圈斷電,動鐵芯與靜鐵芯脫離,關(guān)閉了導(dǎo)閥孔,閥芯背腔壓力受進(jìn)口壓力的補(bǔ)充逐漸趨于和進(jìn)口平衡,閥芯因彈簧力作用下把閥門緊密關(guān)閉。 特點(diǎn):功率消耗低、通徑較大,而結(jié)構(gòu)簡單、安裝方向任意,但只能用于電磁閥兩端有一定壓差的場合,主要應(yīng)用在汽車,電廠,鋼廠,船廠等行業(yè)
原裝正品德國GSR氣動閥門
1)GSR與固定液阻組成先導(dǎo)控制液橋,根據(jù)輸入信號對主閥或次級閥或變量杠進(jìn)行控制;
2)GSR首級先導(dǎo)閥的流量一般都只在1升/分左右,zui大3升/分。二級先導(dǎo)閥流量就要根據(jù)實(shí)際需要決定。
3)GSR輸入信號都比較小;
4)GSR可以接受多種輸入方式,如手動、電動、液動、氣動、機(jī)械凸輪、電比例等;
5)GSR在變量泵控制等情況,多種先導(dǎo)閥形成模塊化結(jié)構(gòu),多種功能取舍方便;
6)GSR先導(dǎo)閥本身往往就是一種小規(guī)格控制閥,多為壓力控制閥。
