自動再循環(huán)閥又稱自動再循環(huán)閥、自動再循環(huán)閥。它主要安裝在離心泵的出口處，作用是當(dāng)離心泵出口流量低于小流量時，自動再循環(huán)閥旁路打開，將泵設(shè)計的小流量經(jīng)旁路回流至泵吸入設(shè)備，避免離心泵因過熱，汽蝕導(dǎo)致?lián)p壞。性能優(yōu)勢1．自動再循環(huán)閥是完全機械結(jié)構(gòu)，由介質(zhì)的流量及壓力來控制閥門，不需要額外的能源。2．自動再循環(huán)閥只在流量很低時才有再循環(huán)，使泵冷卻，在泵正常運行時,并沒有再循環(huán)，從而可節(jié)省因連續(xù)再循環(huán)所消耗的電能和水能。3．小流量閥不需要電氣配線，也不需要兩個調(diào)節(jié)閥串聯(lián)，與傳統(tǒng)控制閥不同的是，我們實現(xiàn)泵保護(hù)只需要一個閥，不再需要執(zhí)行器，流量計與控制單元。</p><p

自動再循環(huán)閥集四種功能于一體:1、流量感知:的主閥瓣能自動感知工藝系統(tǒng)中的主流量,從而根據(jù)此流量來確定主閥瓣和旁路閥瓣的位置.2、再循環(huán)控制:可以將泵正常運行所需要的小流量通過旁路吸入到存儲裝置中,調(diào)節(jié)水泵H-Q特性,實現(xiàn)再循環(huán).3、旁路多級減壓:旁路控制系統(tǒng)能低噪音小磨損的把回流介質(zhì)從泵出口的高壓減至適宜回流存儲裝置中的低壓。4、止回:還具有止回閥的作用,防止液體回流到泵體中。自動再循環(huán)閥用于保護(hù)離心泵，防止泵在低流量工況下由于過熱、嚴(yán)重噪音、不穩(wěn)定和氣蝕而引起的損壞。自動再循環(huán)閥又稱泵保護(hù)閥或小流量閥。湖北自動再循環(huán)閥工廠</p><p

自動再循環(huán)閥的優(yōu)點：1、啟閉方便迅速、省力、流體阻力小，可以經(jīng)常操作。2、結(jié)構(gòu)簡單，外形尺寸小，結(jié)構(gòu)長度短，體積小，重量輕，適用于大口徑的閥門。3、可以運送泥漿，在管道口積存液體少。4、低壓下，可以實現(xiàn)良好的密封。5、調(diào)節(jié)性能好。6、全開時閥座通道有效流通面積較大，流體阻力較小。7、啟閉力矩較小，由于轉(zhuǎn)軸兩側(cè)蝶板受介質(zhì)作用基本相等，而產(chǎn)生轉(zhuǎn)矩的方向相反，因而啟閉較省力。8、密封面材料一般采用橡膠、塑料、故低壓密封性能好。9、安裝方便。10、操作靈活省力，可選擇手動、電動、氣動、液壓方式。寶山區(qū)自動再循環(huán)閥供應(yīng)商</p></p><br
