意大利CAMOZZI VMS系手控閥
汽車行車制動的過程中,停車、住車制動、排氣制動是通過手控閥來實現制動。
發(fa)(fa)(fa)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)制(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)就是排(pai)氣制(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)，對于重型車(che)來說，制(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)主要(yao)有行(xing)車(che)制(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)；停車(che)、住車(che)制(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、排(pai)氣制(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)。行(xing)車(che)制(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)就是通(tong)過(guo)(guo)(guo)雙腔制(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)總閥(fa)(fa)(fa)來實現制(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)，停車(che)、住車(che)制(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)是通(tong)過(guo)(guo)(guo)手控閥(fa)(fa)(fa)來實現制(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)，而排(pai)氣制(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)是通(tong)過(guo)(guo)(guo)排(pai)氣制(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)蝶閥(fa)(fa)(fa)來實現制(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)。排(pai)氣制(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)蝶閥(fa)(fa)(fa)是裝在發(fa)(fa)(fa)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)排(pai)氣軟管后面，當(dang)操(cao)縱按鈕(niu)閥(fa)(fa)(fa)時(shi)，氣壓通(tong)過(guo)(guo)(guo)排(pai)氣制(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)蝶閥(fa)(fa)(fa)的工作(zuo)缸，使工作(zuo)缸內的氣活(huo)塞(sai)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)，從而帶動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)推桿使蝶閥(fa)(fa)(fa)閥(fa)(fa)(fa)片轉(zhuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)90度(du)，關閉(bi)排(pai)氣軟管，使發(fa)(fa)(fa)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)排(pai)氣受阻(zu)，發(fa)(fa)(fa)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)排(pai)氣受阻(zu)時(shi)，那么發(fa)(fa)(fa)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)缸體內的活(huo)塞(sai)就不(bu)能正常(chang)行(xing)程(cheng)，它必需刻服這個阻(zu)力，就這樣在這個空(kong)氣阻(zu)力作(zuo)用，發(fa)(fa)(fa)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)活(huo)塞(sai)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)降低，由于牽引力作(zuo)用，所以車(che)速就慢下來了。

意大利CAMOZZI VMS系手控閥
1、3 和 4 系列：二位三通、二位五通和三位五通，接口 G1/8 和 G1/4
VMS 系列：二位三通，接口 G1/8, G1/4, G3/8, G1/2 和 G3/4
3 和 4 系列手控閥備有多種形式的手
控驅動頭，以滿足各種不同的需要。因
其流量較大，多用于直接控制氣缸，也
可作為大型氣控閥的導閥使用。
對于二位三通手控閥，當 1 為進氣口
時，此閥為常閉（NC）式。當 3 口為進
氣口時，此閥為常開（NO）式。
對于二位五通手控閥，如果需要
個氣缸的工作行程壓力不同于回程壓力
時，可以通過給 3 口和 5 口供給二種不
同的壓力來實現
