威格士電磁閥和安全閥為一體,組成先導(dǎo)式壓力閥,該閥即是卸荷閥又是安全閥,有時(shí)又是溢流閥.卸荷時(shí)其控制油道貫穿各路換向閥,同前述卸荷油道.當(dāng)各路換向閥處于中立位置時(shí),卸荷閥的控制油道(見圖1b和圖2)貫穿各路換向閥并與油箱連通.卸荷時(shí),大部分油液卸荷,通道短,壓力損失低.任一路閥換向工作,便切斷控制油道,油源來油就從換向閥進(jìn)入執(zhí)行元件工作,其工作壓力大小由導(dǎo)閥控制.此時(shí)系統(tǒng)壓力為導(dǎo)閥調(diào)整壓力.該種卸荷方式,即使換向閥路數(shù)增加,只是控制油道增加,卸荷壓力增加不大,始終保持較低卸荷壓力,此種卸荷方式多用于手動換向閥,卸荷可靠.威格士電磁閥(又是安全閥)的主閥按配合形式不同可分為三級同心、二級同心和滑閥式三類.其中滑閥式結(jié)構(gòu)工作壓力低,控制壓力精度不高;三級同心結(jié)構(gòu)雖成熟,目前應(yīng)用較廣,但與二級同心式比較,不及二級同心式動作靈敏,規(guī)格相同,行程相同時(shí),二級同心結(jié)構(gòu)的通油能力遠(yuǎn)大于三級同心結(jié)構(gòu).
