NUMATICS閥芯閥套都用440C不銹鋼制成,經(jīng)超精密配對研磨拋光加工,達(dá)到高精度配合公差,間隙僅*um。當(dāng)氣流經(jīng)閥套上小孔進(jìn)入,在閥芯、閥套間微小間隙中形與-空氣薄膜,閥芯閥套中自動對中。當(dāng)閥芯在這種空氣軸承上運(yùn)動時,象在空氣分子場中一樣,*沒有金屬和金屬間的接觸。同時,其芯套經(jīng)熱處理達(dá)到硬度RC5-62,閥套小孔內(nèi)緣及閥芯凸肩外緣均呈無倒角銳邊狀,這種刃形邊緣形成一把理想的切刀,可切碎任何進(jìn)入閥套小孔的雜質(zhì)顆粒,并由氣流帶走。 在電磁閥方面,NUMATICS閥的心臟---閥芯閥套組件是NUMATICS的設(shè)計(jì)。這種設(shè)計(jì)始于1949年,并于1954年完善地應(yīng)用在四通五路接口閥上。經(jīng)*客戶近50年應(yīng)用實(shí)踐表明,這種結(jié)構(gòu)已經(jīng)成為NUMATICS氣動元件高品質(zhì)的標(biāo)志面*。
在流體工業(yè)中*個開發(fā)的技術(shù)有:
1、閥芯和閥套的概念;
2、5□4通路閥;
3、鋁合金壓鑄閥體;
4、在閥體和底座間的迭加式減壓閥;
5、積木式組合的匯流板;
6、長槽型流路通道模式;
7、直動式電磁閥;
8、迭加式調(diào)速閥;
9、迭加式氣閥的電控聯(lián)接模式;
10、鎂合金閥體,底座和匯流板;
11、精確選擇控制元件的"Numasizing"的軟件。
