自動再循環(huán)閥又稱自動再循環(huán)閥或小流量閥，用于離心泵小流量的自動再循環(huán)，防止離心泵在低負載下由于過熱，噪音、振動帶來的損壞。自動再循環(huán)閥為自力式控制閥，不需要外部供給能源。與傳統(tǒng)的控制閥系統(tǒng)相比，具有以下明顯優(yōu)勢：在前期產(chǎn)品采購、安裝調(diào)試，以及后期的維護方面，具有明顯的成本優(yōu)勢，總體費用比傳統(tǒng)控制閥系統(tǒng)低2/3旁路流量可調(diào)節(jié)控制，閥門整體運行具有高經(jīng)濟性完全機械結(jié)構(gòu)，依靠流量控制閥門，不需要額外的能源。實現(xiàn)泵的保護只只只需一個閥，不需其他額外組件。因此不受系統(tǒng)故障影響。</p><p style="text-indent:25px"> 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)閥用于保護離心泵，防止泵在低流量工況下由于過熱、嚴重噪音、不穩(wěn)定和氣蝕而引起的損壞。自動再循環(huán)閥初度運轉(zhuǎn)時，要供認電動機滾動的方向是不是精確.</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="泵保護閥廠家電話,自動再循環(huán)閥" src="https://tyunfile.71360.com/UploadFile/shdatian/637343241974296875/6282454.png"></div><p style="text-indent:25px"> 自動再循環(huán)閥的目的是只允許水泵往外送水，而不允許水反向流回水泵。防止水泵突然停止運轉(zhuǎn)時，高壓水反向流回水泵造成水泵倒轉(zhuǎn)；小流量閥保證在再循環(huán)系統(tǒng)處于開啟狀態(tài)時高壓水經(jīng)過減壓使閥出口壓力與除氧器（或冷凝器）水箱壓力接近而不致造成除氧器（或冷凝器）水箱壓力震蕩和發(fā)生汽蝕。顯然，再循環(huán)系統(tǒng)中主要的、工作條件惡劣的無疑是小流量閥。自動再循環(huán)閥結(jié)構(gòu)簡單、運行可靠穩(wěn)定，只有少量運動部件；降低了設(shè)備的投資成本；無須熱閃蒸發(fā)生；不須附加電源及控制信號；設(shè)計簡化安裝方便；自動再循環(huán)閥出廠前已經(jīng)調(diào)試好，安裝前不需要解體。上海回流閥價格哪家便宜</p><p style="text-indent:25px">自動再循環(huán)閥在泵正常運行時,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。泵保護閥廠家電話</p><p style="text-indent:25px"> 為了充分發(fā)揮自動再循環(huán)閥的作用，人們對生產(chǎn)工藝進行了嚴格的檢查，只只是鋁翅片結(jié)構(gòu)就會有多道清洗程序，目的就是實現(xiàn)順暢地流通，這樣才能夠保證換熱效果。具體來說，自動再循環(huán)閥有以下特點：首，換熱效果好，無論是鋁翅片還是銅管，都經(jīng)過了嚴苛的篩選，材質(zhì)的優(yōu)異以及做工的精良，讓自動再循環(huán)閥具有較高的傳熱效率，可以克服阻力影響。第二，使用壽命長，自動再循環(huán)閥的材質(zhì)決定了其具有緊密的結(jié)構(gòu)外形，同時兼具輕便的重量，更值得稱贊的是其具有較高的承重性和抗壓性。第三，應用范圍廣，可以適用于不同規(guī)格的空調(diào)和制冷工程，可以單獨使用，也可以配套使用，組合方式靈活便利，操作簡單。泵保護閥廠家電話</p></p><br
