換向閥

作用:

利用閥芯相對于閥體間的相對位置改變，使油路接通、關(guān)斷，或改變油流的方向，從而使液壓執(zhí)行元件啟動、停止或變換運(yùn)動方向。

1、對換向閥的性能要求

(1)油液導(dǎo)通時壓力損失要小;

(2)油液斷開時泄漏要小;

(3)閥芯換位時操縱力要小。

2、類型

按閥芯的形狀分類滑閥、轉(zhuǎn)閥

按閥的安裝方式分類:管式、板式、法蘭式。

按操縱方式分類: 

手動、機(jī)動、電動、彈簧控制、液動、液壓先導(dǎo)控制、電液動等。

WE型電磁換向閥采用濕式交流或直流電磁鐵。該閥是通過電磁鐵控制閥芯的不同工作位置。當(dāng)電磁鐵斷電時，閥芯靠彈簧壓力保持在中間或終端位置(脈沖式閥除外)。電磁鐵通電，閥芯被推到工作位置上，斷電后又恢復(fù)到初始狀態(tài)。這時用手推動故障檢查按鈕可使閥芯移動。

換向閥可分為手動換向閥、電磁換向閥、電液換向閥等。

又稱克里斯閥，閥門的一種，具有多向可調(diào)的通道，可適時改變流體流向。

工作時借著閥外的驅(qū)動傳動機(jī)構(gòu)轉(zhuǎn)動驅(qū)動軸，帶動搖拐臂，啟動閥板，使工作流體時而從左入口通向閥的下部出口，時而從右入口變換通向下部出口，實(shí)現(xiàn)了周期變換流向的目的。這種變換閥在石油、化工生產(chǎn)中有著廣泛的應(yīng)用，在合成氨造氣系統(tǒng)中較為常用。此外，換向閥還可作成閥瓣式的結(jié)構(gòu)，多用于較小流量的場合。工作時只需轉(zhuǎn)動手輪通過閥瓣來變換工作流體的流向。

安全閥是啟閉件受外力作用下處于常閉狀態(tài)，當(dāng)設(shè)備或管道內(nèi)的介質(zhì)壓力升高超過規(guī)定值時，通過向系統(tǒng)外排放介質(zhì)來防止管道或設(shè)備內(nèi)介質(zhì)壓力超過規(guī)定數(shù)值的特殊閥門。安全閥屬于自動閥類，主要用于鍋爐、壓力容器和管道上，控制壓力不超過規(guī)定值，對人身安全和設(shè)備運(yùn)行起重要保護(hù)作用。注安全閥必須經(jīng)過壓力試驗(yàn)才能使用。
