特征:
成熟產(chǎn)品 久經(jīng)考驗
結構緊湊
常閉型和常開型
也可用作為 2/2 閥
原理:
提升閥(Poppet valve),有時稱為錐閥,菌形閥,菌裝閥。其
蓋有薄膜。薄膜由陶瓷制成。在閥頭的前面固定有隔熱板,以
在活塞式發(fā)動機中的用來控制空氣的進入,提升閥在氣門導管
中運行。提升閥包括閥頭和閥桿,用于內(nèi)燃機。閥頭的表面覆
便在前面和隔熱板之間形成絕熱空間,由此降閥的運行溫度
實物圖:
分步直動式電磁閥:
原理:它是一種直動和先導式相結合的原理,當入口與出口沒
有壓差時,通電后,電磁力直接把先導小閥和主閥關閉件依次
,電磁力先導小閥,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;斷電時,先導閥利用彈簧力或介質(zhì)
向上提起,閥門打開。當入口與出口達到啟動壓差時,通電后
壓力推動關閉件,向下移動,使閥門關閉。
特點:在零壓差或真空、高壓時亦能可*動作,但功率較大,要
求必須水平安裝。
