style="text-indent:25px">由于上游的泵，彎頭或其他流量干擾，即使是尺寸合適的止回閥在處理湍流時(shí)也可能會(huì)不穩(wěn)定。優(yōu)良作法是在閥的上游留出一定長(zhǎng)度的直管，以使湍流消散（如果有空間的話(huà)）。通常，長(zhǎng)度為10D就足夠了。止回閥在保護(hù)流量系統(tǒng)中的其他組件方面起著重要作用。為了完成其工作，每個(gè)止回閥都必須是適合于應(yīng)用的類(lèi)型，并且需要正確設(shè)置尺寸，以使其在正常工作流量下保持完全打開(kāi)。正確選擇和選擇尺寸的止回閥可以具有較長(zhǎng)的無(wú)故障工作壽命。止回閥用于管路系統(tǒng)，作用是為了防止介質(zhì)倒流、防止泵及其啟動(dòng)電機(jī)反轉(zhuǎn)，以及容器內(nèi)介質(zhì)的泄放。止回閥還可用于給其中的壓力可能升至超過(guò)主系統(tǒng)壓力的輔助系統(tǒng)提供補(bǔ)給的管路上。止回閥安裝在管路上，即成為這一完整的流體部件之一，其閥瓣啟閉過(guò)程就要受它所處系統(tǒng)瞬變流動(dòng)狀態(tài)所影響；反之，閥瓣的關(guān)閉特性又對(duì)流體流動(dòng)狀態(tài)產(chǎn)生作用。西藏止回閥價(jià)格表升降式較旋啟式密封性好，流體阻力大，臥式宜裝在水平管道上，立式裝在垂直管道上。</p><div

style="text-indent:25px">對(duì)于要求關(guān)閉時(shí)水擊沖擊比較小或無(wú)水擊的管路，宜選用緩閉式旋啟止回閥和緩閉式蝶形止回閥。了解進(jìn)口壓力將有助于確定您需要哪種類(lèi)型的止回閥。您需要一個(gè)“球形”式止回閥嗎？您需要求一個(gè)“旋啟式”止回閥嗎？或者您需要一個(gè)消聲式止回閥？還是法蘭止回閥或?qū)A接止回閥？確定您需要哪種止回閥取決于止回閥在泵體系中的方位。背壓是進(jìn)口和出口壓力之間的壓差。例如，一個(gè)閥安裝在將流體排入小口徑的管道的結(jié)尾。當(dāng)流量上升時(shí)，水面上方的水會(huì)有多高？當(dāng)水上升到該閥上方時(shí)，發(fā)生背壓。因此，根據(jù)您的詳細(xì)使用，您應(yīng)該知道止回閥需要接受多大的背壓。如果閥門(mén)安裝后處于浸沒(méi)在介質(zhì)中的狀態(tài)，這意味著閥門(mén)上總是有背壓。在這種情況下，您需要挑選一個(gè)用于浸沒(méi)條件并由正確材料制造的止回閥，以適將錯(cuò)的止回閥放入管道體系中的錯(cuò)誤是比較常見(jiàn)的。如果您的止回閥頻頻出現(xiàn)問(wèn)題，可能是挑選不妥造成的。</p><p

style="text-indent:25px">由于止回閥在沒(méi)有使用者的情況下運(yùn)行，因此需要壓力差來(lái)操作。對(duì)于從入口到出口穿過(guò)閥門(mén)的流動(dòng)，需要更高的上游壓力。閥門(mén)工作的入口和出口之間的較小差異稱(chēng)為“開(kāi)啟壓力”，其根據(jù)閥門(mén)尺寸和設(shè)計(jì)而變化。如果出口側(cè)有較高的壓力，流量將嘗試向后移動(dòng)通過(guò)止回閥。它被設(shè)計(jì)成由于這種“背壓”而關(guān)閉。由于止回閥允許在一個(gè)方向上流動(dòng)，因此以正確的方向安裝是至關(guān)重要的。通常，有一個(gè)箭頭清楚地描繪了方向，如圖1所示。如果向后安裝，介質(zhì)將無(wú)法沿所需的流向移動(dòng)閥門(mén)。根據(jù)閥門(mén)的設(shè)計(jì)，它們的運(yùn)行方式略有不同。彈簧式內(nèi)聯(lián)止回閥是較常見(jiàn)的。還有其他類(lèi)型的特殊功能，如入口過(guò)濾器，柔性膜片或機(jī)械超控桿，但它們不太常見(jiàn)。對(duì)于水泵進(jìn)口管路，宜選用底閥，底閥一般只安裝在泵進(jìn)口的垂直管道上，并且介質(zhì)自下而上流動(dòng)。西藏止回閥價(jià)格表</p><p

style="text-indent:25px">要保持止回閥完全打開(kāi)，通常需要每秒10到12英尺的流體速度，例如水。要開(kāi)始打開(kāi)止回閥，“破裂壓力”大約需要4到8英尺/秒。保持止回閥打開(kāi)的壓降通常是開(kāi)啟壓力的二到五倍。止回閥過(guò)大會(huì)導(dǎo)致流速低，從而無(wú)法保持閥門(mén)始終打開(kāi)。這會(huì)導(dǎo)致不穩(wěn)定，閥可能會(huì)顫動(dòng)或顫動(dòng)。反過(guò)來(lái)，由于頻繁地更換閥門(mén)/閥芯，以及由于修理或更換止回閥而導(dǎo)致的其他系統(tǒng)停機(jī)，這會(huì)導(dǎo)致閥門(mén)過(guò)早的機(jī)械磨損以及可能帶來(lái)的額外維護(hù)成本。止回閥尺寸過(guò)小會(huì)導(dǎo)致通過(guò)該閥的流量過(guò)高，從而導(dǎo)致系統(tǒng)中不必要的高壓力損失。它還可能在流中產(chǎn)生過(guò)度的湍流，這可能導(dǎo)致閥不穩(wěn)定并增加機(jī)械磨損，從而導(dǎo)致更高的維護(hù)成本。同樣，通過(guò)尺寸過(guò)小的閥門(mén)的較高流速可能會(huì)增加閥門(mén)內(nèi)部的腐蝕磨損。西藏止回閥價(jià)格表</p><p
