- 液壓系統(tǒng)先導式溢流閥工作原理與結構特點
- 先導式溢流閥的工作原理和結構。
- 先導式溢流閥的工作原理:
- 當壓力油從入口流入時,壓力作用在主閥芯下端平面上。閥體內部設計有阻尼孔,壓力油通過后進入先導閥的右腔,并最終作用于先導溢流閥的閥芯上。先導溢流閥的閥芯受彈簧推力而處于常閉狀態(tài),通過外部的調節(jié)手柄,可對彈簧的預調壓力做出調整。當液壓壓力小于彈簧預調壓力時,先導閥芯始終處于封閉狀態(tài),此時主閥芯亦無相應動作。當液壓系統(tǒng)壓力上升,導緻先導閥內部液壓壓力大于彈簧預調壓力,先導閥開啓,在阻尼孔的降壓作用下,主閥芯上、下産生壓力差,因此主閥芯上抬,原本密封的進油路以及出油路相通,壓力油直接從進油口到出油口,實現(xiàn)卸荷。
- 先導式溢流閥的結構:
- 先導式溢流閥,其結構分爲兩個部分,先導部分是一個小規(guī)格的直動式溢流閥,其與主閥相連,兩者構成先導式溢流閥。這樣的結構特點使先導式溢流閥調節(jié)力矩大大小于直動式溢流閥,并且啓閉特性好。
- 先導式溢流閥根據使用環(huán)境的要求,可以選擇內控內洩,內控外洩,外控內洩,外控外洩等多種控制形式。內控內洩,指控制先導溢流閥的液壓油直接由進口P口引入,先導控制閥溢流出的油液與主溢流閥溢流的油液一起,從閥的T口流出。外控,則主閥進油口P與先導溢流閥控制腔的油路被阻斷,單獨引入控制油液從控制口X口進入。外洩,則先導溢流閥溢流后的油液不通過主回路,單獨通過洩油口Y口洩油。
- 溢流閥由于其結構特點決定不適合用于大流量液壓泵站中。一方面大流量環(huán)境直接造成溢流閥的調節(jié)手柄旋轉困難,甚至無法調節(jié),影響工作。另一方面直動式溢流閥的結構造成其啓閉特性相對比較差。因此直動式溢流閥用于小流量,要求不高 的液壓系統(tǒng)中。針對大流量,高精密要求的液壓站,一般選用先導式溢流閥。
