比例閥采用閥芯+閥體結構。伺服閥和伺服比例閥主要應用在閉環控制系統,比例閥的驅動裝置是比例電磁鐵。
伺服閥的驅動裝置是力馬達或力矩馬達.閥體兼作閥套。
驅動裝置不同.所以近些年出現了比例伺服閥。
比例閥一般zui高幾十Hz,伺服閥中位沒有死區,伺服閥對液壓油液的要求更高.性能參數不同;否則容易堵塞,
用來控制流量和流向,比例閥要求低一些.比例閥有中位死區;
比例閥和伺服閥的區別主要體現在以下幾點:
逐漸向伺服閥靠近,
比例換向閥屬于比例閥的一種,滯環、中位死區、頻寬、過濾精度等特性不同.閥的額定壓降不同;比例換向閥具有與普通換向閥相似的中位機能,
而比例伺服閥性能介于伺服閥和比例閥之間,因此應用場合不同,伺服閥和伺服比例閥采用閥芯+閥套的結構。中位機能種類不同.其它結構的比例閥主要應用在開環控系統及閉環速度控制系統;因為比例閥的性能越來越好;2伺服閥的頻響(響應頻率)更高。閥芯結構及加工精度不同.伺服閥與比例閥之間的差別并沒有嚴格的規定。
,可以高達200Hz左右,需要精過濾才行,而伺服閥中位機能只有O型(Rexroth產品的E型)。

KKDSR1PB/HCG12N0K4V 普通溢流閥與比例溢流閥一樣,都有一個閥芯,閥芯的一端是液壓油產生的壓力,另一端是機械力。普通溢流閥通過調節彈簧力,來調整液壓壓力。而比例溢流閥是電磁鐵直接產生推力,作用在閥芯上,電磁鐵上的輸入電壓可以在0-24伏之間變化,產生的推力就隨之變化,從而得到連續變化的液壓壓力。
因為比例電磁鐵的推力不大,所以直動式比例溢流閥的流量很小,壓力70兆帕時,流量只有1升/分鐘左右。需要大流量比例閥的時候,要把這個比例閥做先導閥,下面還要配一個大通徑的溢流閥。
電磁溢流閥和比例溢流閥功能上區別不是太大,都是在系統壓力超過設定值時開啟卸壓、溢流;不同的是,比例溢流閥可以按比例調定溢流的流量,對系統的控制更加精密。普通的溢流閥就是開啟和關閉兩個位置,比例閥在開啟溢流時可以有多個位置。
rexroth比例插裝節流閥主要用于多泵并聯使用時安裝于水泵壓出口,起限制水泵工作流量,防止停泵回流作用。該閥采用導閥,主閥構造,結構緊湊,重量較輕。該閥安裝于水泵出口,在單泵啟動和非全數設計工作泵工作時,對工作泵起限制流量作用,使泵在較高效率狀態下工作;防止電動機在水泵低揚程、大流量、低效率時,發生過載現象;防止超額定電流燒電機現象的發生,同時起到一定的節能效果。
rexroth比例插裝節流閥和安全閥為一體,組成先導式壓力閥,該閥即是卸荷閥又是安全閥,有時又是溢流閥.卸荷時其控制油道貫穿各路換向閥,同前述卸荷油道.當各路換向閥處于中立位置時,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,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入執行元件工作,其工作壓力大小由導閥控制.此時系統壓力為導閥調整壓力.該種卸荷方式,即使換向閥路數增加,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.
rexroth比例插裝節流閥與直接作用自力式控制閥類似,其設定信號由指揮器的設定彈簧設置。如果閥后壓力升高,表示膜頭l下面的壓力高于上面壓力,閥芯3上移,控制閥的流通面積減小,使閥后壓力下降。同時,作用在指揮器膜片4的壓力也升高,其作用-力大于由設定彈簧5提供的作用力,使指揮器組件6移動,擋板7??拷鼑娮?,指揮器輸出壓力隨之減小,即在膜頭l上面壓力減小,使閥芯3上移,直到閥后壓力與設定彈簧的作用力平衡為止。針閥2用于調節放大系數,過濾器9用于過濾介質中的顆粒雜質,防止噴嘴被堵塞。另有一種采用重錘作為設定的自力式壓力控制閥。重錘經杠桿連接到閥桿。
