style="text-indent:25px">壓力控制閥（pressurecontrolvalve）是制壓力的閥的總稱。在平常中我們都把控制壓力的閥的統(tǒng)稱為壓力控制閥。壓力控制閥有時(shí)候也簡(jiǎn)稱為壓力閥，主要是用來(lái)滿足對(duì)執(zhí)行機(jī)構(gòu)提出的力或力矩的要求。包括安全閥、溢流閥、減壓閥和順序閥。壓力控制閥是制壓力的閥的總稱。下面給大家舉例：電磁閥：電磁閥是用來(lái)控制流體的自動(dòng)化基礎(chǔ)元件，屬于執(zhí)行器；并不限于液壓，氣動(dòng)用于控制液壓流動(dòng)方向，工廠的機(jī)械裝置一般都由液壓鋼控制，所以就會(huì)用到電磁閥。</p><p style="text-indent:25px">節(jié)流閥是通過(guò)改變節(jié)流截面或節(jié)流長(zhǎng)度以控制流體流量的閥門。將節(jié)流閥和單向閥并聯(lián)則可組合成單向節(jié)流閥。節(jié)流閥和單向節(jié)流閥是簡(jiǎn)易的流量控制閥，在定量泵液壓系統(tǒng)中，節(jié)流閥和溢流閥配合，可組成三種節(jié)流調(diào)速系統(tǒng)，即進(jìn)油路節(jié)流調(diào)速系統(tǒng)、回油路節(jié)流調(diào)速系統(tǒng)和旁路節(jié)流調(diào)速系統(tǒng)。節(jié)流閥沒(méi)有流量負(fù)反饋功能，不能補(bǔ)償由負(fù)載變化所造成的速度不穩(wěn)定，一般*用于負(fù)載變化不大或?qū)λ俣确€(wěn)定性要求不高的場(chǎng)合。對(duì)節(jié)流閥的性能要求是：流量調(diào)節(jié)范圍大，流量一壓差變化平滑；內(nèi)泄漏量小，若有外泄漏油口，外泄漏量也要??；調(diào)節(jié)力矩小，動(dòng)作靈敏。液壓閥用于降低并穩(wěn)定系統(tǒng)中某一支路的油液壓力。</p><div

style="text-indent:25px">換向型方向控制閥(簡(jiǎn)稱換向閥)，是通過(guò)改變氣流通道而使氣體流動(dòng)方向發(fā)生變化，從而達(dá)到改變氣動(dòng)執(zhí)行元件運(yùn)動(dòng)方向目的。它包括氣壓控制換向閥、電磁控制換向閥、機(jī)械控制換向閥、人力控制換向閥和時(shí)間控制換向閥等一個(gè)完整的液壓系統(tǒng)由五個(gè)部分組成。液壓閥是用來(lái)控制液壓系統(tǒng)中油液的流動(dòng)方向或調(diào)節(jié)其壓力和流量的，因此它可分為方向閥、壓力閥和流量閥三大類。一個(gè)形狀相同的閥，可以因?yàn)樽饔脵C(jī)制的不同，而具有不同的功能。壓力閥和流量閥利用通流截面的節(jié)流作用控制著系統(tǒng)的壓力和流量，而方向閥則利用通流通道的更換控制著油液的流動(dòng)方向。這就是說(shuō)，盡管液壓閥存在著各種各樣不同的類型，它們之間還是保持著一些基本共同之點(diǎn)的。一個(gè)液壓系統(tǒng)，不論其如何簡(jiǎn)單，都不能缺少液壓閥。連云港氣動(dòng)液壓閥</p><p style="text-indent:25px">流量閥適用于需要進(jìn)行流量控制的水系統(tǒng)中，尤其適合于供熱。安徽手動(dòng)液壓閥</p><p style="text-indent:25px">分流集流閥按調(diào)整方式分為：固定式分流集流閥，可調(diào)式分流集流閥和自調(diào)式分流集流閥。其中固定式結(jié)構(gòu)同步閥又可分為換向活塞式和掛鉤式兩種結(jié)構(gòu)。分流集流閥按流量分配方式還可分為：等流量式和比例流量式，比例流量常采用2:1流量分配方式。分流集流閥主要應(yīng)用于液壓雙缸及多缸同步控制系統(tǒng)中。實(shí)現(xiàn)同步運(yùn)動(dòng)的方法很多，但其中以采用分流集流閥的同步控制液壓系統(tǒng)具有結(jié)構(gòu)簡(jiǎn)單、成本低、設(shè)計(jì)、成套、調(diào)試和使用容易、可靠性強(qiáng)等許多優(yōu)點(diǎn)，因而分流集流閥在液壓系統(tǒng)中得到了普遍的應(yīng)用。安徽手動(dòng)液壓閥</p><p
