特征:
成熟產(chǎn)品 久經(jīng)考驗(yàn)
結(jié)構(gòu)緊湊
常閉型和常開(kāi)型
也可用作為 2/2 閥
原理:
提升閥(Poppet valve),有時(shí)稱(chēng)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(dòng)機(jī)中的用來(lái)控制空氣的進(jìn)入,提升閥在氣門(mén)導(dǎo)管
中運(yùn)行。提升閥包括閥頭和閥桿,用于內(nèi)燃機(jī)。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(yùn)行溫度
分步直動(dòng)式電磁閥:
原理:它是一種直動(dòng)和先導(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,電磁力直接把先導(dǎo)小閥和主閥關(guān)閉件依次
,電磁力先導(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),先導(dǎo)閥利用彈簧力或介質(zhì)
向上提起,閥門(mén)打開(kāi)。當(dāng)入口與出口達(dá)到啟動(dòng)壓差時(shí),通電后
壓力推動(dòng)關(guān)閉件,向下移動(dòng),使閥門(mén)關(guān)閉。
特點(diǎn):在零壓差或真空、高壓時(shí)亦能可*動(dòng)作,但功率較大,要
求必須水平安裝。
