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(yùn)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(yùn)行可靠穩(wěn)定，只有少量運(yùn)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；浙江自動三通回流閥廠家哪家便宜自動再循環(huán)閥可以設(shè)置自動控制.</p><div

自動再循環(huán)閥具有止回功能，阻止介質(zhì)回流到泵內(nèi)。自動再循環(huán)閥的特點1、流量感知：自動再循環(huán)閥（自動再循環(huán)閥）能感知工藝系統(tǒng)中的主流量，并根據(jù)此流量來確定其閥芯的具位置置;2、再循環(huán)控制：自動再循環(huán)閥可將泵正常運(yùn)轉(zhuǎn)所需的小流量旁通到泵吸入水箱或冷凝水箱中，防止泵過熱;3、多級降壓：旁路控制系統(tǒng)能低噪單小磨損地把加流液體從其高壓感至適宜的低壓（泵吸水箱中壓力）;4、止回作用：自動再循環(huán)閥也可作為止回閥使用，阻止流體回流到液泵內(nèi);多功能控制閥自動再循環(huán)閥。</p><p style="text-indent:25px"> 隨著防化學(xué)腐蝕的合成橡膠在自動再循環(huán)閥上的應(yīng)用，自動再循環(huán)閥的性能得以提高。由于合成橡膠具有耐腐蝕、抗沖蝕、尺寸穩(wěn)定、回彈性好、易于成形、成本低廉等特點，并可以根據(jù)不同的使用要求選擇不同性能的合成橡膠，以滿足自動再循環(huán)閥的使用工況條件。由于聚四氟乙烯(PTFE)具有耐腐蝕性強(qiáng)、性能穩(wěn)定、不易老化、摩擦系數(shù)低、易于成形、尺寸穩(wěn)定，并且可以通過填充、添加適當(dāng)?shù)牟牧细纳破渚C合性能，得到強(qiáng)度更好、摩擦系數(shù)更低的自動再循環(huán)閥密封材料，克服了合成橡膠的局限性。自動再循環(huán)閥應(yīng)及時排除管道中的積氣.</p><div

自動再循環(huán)閥對保護(hù)給水泵，避免水泵葉輪汽蝕損壞，保證整個機(jī)組正常運(yùn)行起到了至關(guān)重要的作用。由于鍋爐剛啟動時流量小，壓差大，預(yù)期可能出現(xiàn)氣蝕和沖刷；隨著鍋爐的啟動，流量隨之增大而壓差將逐漸變小，對閥門的流通能力要求極高；當(dāng)鍋爐恢復(fù)正常運(yùn)行時又必須具備快速關(guān)閉和緊急密封功能。因此自動再循環(huán)閥必須具備以下特點方能勝任此惡劣工況：抗汽蝕，保護(hù)給水泵并提高給水泵效率；具備大流通能力，并能預(yù)防卡塞；具備V或VI級密封，快速開啟/關(guān)閉功能。自動再循環(huán)閥具有止回功能，阻止介質(zhì)回流到泵內(nèi)。蕪湖自動再循環(huán)閥什么牌子好</p><p style="text-indent:25px">自動再循環(huán)閥在完全開啟時，具有較小的流阻.當(dāng)開啟在大約15°~70°之間時.浙江自動三通回流閥廠家哪家便宜</p><p style="text-indent:25px"> 排空止回閥安裝在火電機(jī)組的高壓給水泵出口管道上,防止給水倒流,保護(hù)給水泵.該閥配合水泵小流量自動再循環(huán)旁閥工作,當(dāng)給水泵在低負(fù)荷或者出口截門關(guān)閉狀態(tài)時,自動再循環(huán)旁路閥應(yīng)處于開啟位置,以保證水泵的安全運(yùn)行.當(dāng)空排止回閥開啟時,再循環(huán)旁路閥就自動關(guān)閉。作用原理及結(jié)構(gòu)特點：打開出口閥，給水泵啟動，給水達(dá)到一定的壓力后，空排止回閥的閥芯自動升起，推離閥座，給水即流出。同時閥芯連桿拔動排空口閥片封閉排空口。當(dāng)給水泵流量減小時，閥芯下落，推動連桿拔開排空閥片，開啟再循環(huán)門維持水泵小流量。當(dāng)停泵時，閥芯自動下落關(guān)閉通道，從而防止高壓水錘對給水系統(tǒng)的破壞。浙江自動三通回流閥廠家哪家便宜</p></p><br
