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)中為常用。此外，換向閥還可作成閥夠式的結(jié)構(gòu)，多用于小流量的場(chǎng)合。工作時(shí)只要轉(zhuǎn)動(dòng)手輪通過(guò)閥鏈來(lái)變換工作流體的流向。
換向閥分類(lèi)
(1)機(jī)動(dòng)換向閥，機(jī)動(dòng)換向閥又稱行程閥
(2)電磁換向閥，電磁換向閥是利用電磁吸引力提縱閥芯換位的方向控制閥
(3)電波換向閥，電波換向閥是由電磁換向閥和液動(dòng)換向閥組成的復(fù)合閥。
(4)手動(dòng)換向閥，手動(dòng)換向閥是用手推杠桿操縱閥芯換位的方向控制閥。

手拉閥特點(diǎn)

1、手動(dòng)操作,方向與軸芯同軸,操作方便,定位準(zhǔn)確、可靠;

2、滑柱式結(jié)構(gòu),密封性好,體積小、重量輕、裝拆方便;

3、內(nèi)孔採(cǎi)用特殊工藝加工,磨擦阻力小,使用壽命長(zhǎng);

4、無(wú)需加油潤(rùn)滑;

5、多位置安裝,安裝使用方便;
