style="font-size:16px;">水利控制閥按結(jié)構(gòu)可分為隔膜型和活塞型兩類，工作原理相同，都是以上下游壓力差P為動(dòng)力，由導(dǎo)閥控制，使隔膜(活塞)液壓式差動(dòng)操作，完全由水力自動(dòng)調(diào)節(jié)，從而使主閥閥盤完全開(kāi)啟或完全關(guān)閉或處于調(diào)節(jié)狀態(tài)。當(dāng)進(jìn)入隔膜(活塞)上方控制室內(nèi)的壓力水被排到大氣或下游低壓區(qū)時(shí)，作用在閥盤底部和隔膜下方的壓力值就大于上方的壓力值。所以將主閥閥盤推到完全開(kāi)啟的位置;當(dāng)進(jìn)入隔膜(活塞)上方控制室內(nèi)的壓力水不能排到大氣或下游低壓區(qū)時(shí)，作用在隔膜(活塞)上方的壓力值就大于下方的壓力值，所以就會(huì)把主閥閥盤壓到完全關(guān)閉的位置;當(dāng)隔膜(活塞)上方控制室內(nèi)的壓力值處于入口壓力與出口壓力中間時(shí)，主閥閥盤就處于調(diào)節(jié)狀態(tài)，其調(diào)節(jié)位置取決于導(dǎo)管系統(tǒng)中的針閥和可調(diào)導(dǎo)閥的聯(lián)合控制作用?？烧{(diào)導(dǎo)閥可以通過(guò)下游的出口壓力并隨它的變化而開(kāi)大或關(guān)小其自身的小閥口，從而改變隔膜(活塞)上方控制室的壓力值，控制方閥閥盤的調(diào)節(jié)位置。</span> </p><p> <span style="font-size:16px;">水力控制閥是一系列多用途控制與安全類閥門的總稱。水力控制閥*依靠介質(zhì)———水的能量，即可實(shí)現(xiàn)對(duì)壓力、流量、液位等的控制。根據(jù)給水系統(tǒng)中不同的設(shè)計(jì)要求和使用要求，還可以演變出十幾種用途的閥門（目前國(guó)外此類閥門已派生出近百種用途）。經(jīng)常用到的有先導(dǎo)式減壓閥、泄壓安全閥、遙控浮球閥等。簡(jiǎn)單來(lái)說(shuō)，水力控制閥是由主閥和不同的導(dǎo)閥系統(tǒng)所組成的。通過(guò)裝配不同的導(dǎo)閥系統(tǒng)，水力控制閥將可以具備不同的使用功能該閥安裝于管路中，主要穩(wěn)定出口壓在設(shè)定的范圍，保證出口的壓力不因進(jìn)口壓力的變化而變化，當(dāng)出口壓力低于設(shè)定值時(shí)，閥瓣在彈簧力的作用下打開(kāi)，水流通過(guò)，當(dāng)出口壓達(dá)到設(shè)定值時(shí)，出口壓直接傳遞與膜片下方，與彈簧形成對(duì)抗，使閥瓣關(guān)閉切斷通水。</span> 水力控制閥的分類和工作原理.</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="海南州水力控制閥生產(chǎn)廠家,水力控制閥"

style="font-size:16px;">水利控制閥無(wú)需操作控制。當(dāng)水泵啟停時(shí)，巧妙地利用閥門兩端的介質(zhì)及其壓力差作為驅(qū)動(dòng)介質(zhì)和控制動(dòng)力，使閥門自動(dòng)按水泵操作規(guī)程的要求進(jìn)行動(dòng)作。水利控制閥無(wú)需專業(yè)調(diào)試。閥門動(dòng)作不受液位高差和出水壓力以及水泵流量變化的影響，適應(yīng)范圍廣。基本無(wú)需維修，壽命長(zhǎng)。水利控制閥使用前要安裝過(guò)濾器，并應(yīng)便于排污的要求。多功能水力控制閥隨介質(zhì)的液位和壓力的變化而動(dòng)作，由于導(dǎo)閥種類很多，可以單獨(dú)使用或幾個(gè)組合使用，就可以使主閥獲得對(duì)水位和水壓及流量等進(jìn)行單獨(dú)和復(fù)合調(diào)節(jié)的功能。但主閥閥體類似截止閥，閥門全開(kāi)時(shí)，其壓力損失比其他閥門要大得多，且各個(gè)開(kāi)度損失系數(shù)越是與全閉狀態(tài)接近，越是劇增，閥門口徑越大。水利控制閥安全可靠性高。消除水錘裝置與閥門啟閉動(dòng)作完全聯(lián)鎖，</span><span
