1、選材考究，符合國(guó)內(nèi)、外相關(guān)標(biāo)準(zhǔn)，材料的質(zhì)量高。 2、密封副配對(duì)先進(jìn)合理，閥瓣、閥座密封面采用鐵基合金或鈷基硬質(zhì)合金堆焊面成，耐磨、耐高溫、耐腐蝕、抗擦傷性能好，使用壽命長(zhǎng)。 3、產(chǎn)品按國(guó)家標(biāo)準(zhǔn)GB/T12235設(shè)計(jì)制造。閥門(mén)承壓件采用精密鑄造工藝澆鑄，表面質(zhì)量美觀，無(wú)粘沙、冷隔等表面破損;內(nèi)在質(zhì)量穩(wěn)定，無(wú)疏松、砂眼、裂紋等內(nèi)在破損。 4、可采用各種配管法蘭標(biāo)準(zhǔn)及法蘭密封型式，滿足各種工程需要及用戶要求。 5、閥體材料品種齊全，墊片可根據(jù)實(shí)際工況或用戶要求合理選配，能適用于各種壓力、溫度及介質(zhì)工況。可按用戶要求設(shè)計(jì)制造不同結(jié)構(gòu)形式和連接形式的止回閥，為各種設(shè)備配套使用。 6,用于管路系統(tǒng)，其主要作用是防止介質(zhì)倒流、防止泵及其驅(qū)動(dòng)電機(jī)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。安徽自密封升降止回閥廠家止回閥又稱(chēng)單向閥或逆止閥，其作用是防止管路中的介質(zhì)倒流。</p><div

style="text-indent:25px">蝶式止回閥的閥瓣呈圓盤(pán)狀，繞閥座通道的轉(zhuǎn)軸作旋轉(zhuǎn)運(yùn)動(dòng)，因閥內(nèi)通道成流線型，流動(dòng)阻力比升蝶式止回閥小，適用于低流速和流動(dòng)不常變化的大口徑場(chǎng)合，但不宜用于脈動(dòng)流，其密封性能不及升降式。蝶式止回閥分單瓣式、雙瓣式和多瓣式三種，這三種形式主要按閥門(mén)口徑來(lái)分，目的是為了防止介質(zhì)停止流動(dòng)或倒流時(shí)，減弱水力沖擊。管道式止回閥：閥瓣沿著閥體中心線滑動(dòng)的閥門(mén)。管道式止回閥是新出現(xiàn)的一種閥門(mén)，它的體積小，重量較輕，加工工藝性好，是止回閥發(fā)展方向之一。但流體阻力系數(shù)比旋啟式止回閥略大。</p><p style="text-indent:25px">止回閥的選型標(biāo)準(zhǔn)內(nèi)容如下：球形止回閥1、為了防止介質(zhì)逆流，在設(shè)備、裝置和管道上都應(yīng)安裝止回閥；2、止回閥一般適用于清凈介質(zhì)，不宜用于含有固體顆粒和粘度較大的介質(zhì)；3、一般在公稱(chēng)通徑50mm的水平管道上都應(yīng)選用臥式升降止回閥；4、直通式升降止回閥只能在水平管道安裝；5、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)；6、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；7、旋啟式止回閥的安裝位置不受限制，它可裝在水平、垂直或傾斜的管線上，如裝在垂直管道上，介質(zhì)流向要由下而上；8、旋啟式止回閥不宜制成小口徑閥門(mén)、可以做成很高的工作壓力，公稱(chēng)壓力可達(dá)到42MPa，而且公稱(chēng)通徑也可以做到很大，比較大可以達(dá)到2000mm以上。根據(jù)殼體及密封件的材質(zhì)不同可以適用任何工作介質(zhì)和任何工作溫度范圍。介質(zhì)為水、蒸汽、氣體、腐蝕性介質(zhì)、油品、藥品、等。介質(zhì)工作溫度范圍在-196--800℃之間。旋啟式止回閥有一介鉸鏈機(jī)構(gòu)，還有一個(gè)像門(mén)一樣的閥瓣自由地靠在傾斜的閥座表面上。</p><div

style="text-indent:25px">止回閥的作用是只允許介質(zhì)向一個(gè)方向流動(dòng)，而且阻止方向流動(dòng)。這種閥門(mén)是自動(dòng)工作的，在一個(gè)方向流動(dòng)的流體壓力作用下，閥瓣打開(kāi)；流體反方向流動(dòng)時(shí)，由流體壓力和閥瓣的自重合閥瓣作用于閥座，從而切斷流動(dòng)。旋啟式止回閥有一介鉸鏈機(jī)構(gòu)，還有一個(gè)像門(mén)一樣的閥瓣自由地靠在傾斜的閥座表面上。為了確保閥瓣每次都能到達(dá)閥座面的合適位置，閥瓣設(shè)計(jì)在鉸鏈機(jī)構(gòu)，以便閥瓣具有足夠有旋啟空間，并使閥瓣真正的、全方面的與閥座接觸。閥瓣可以全部用金屬制成，也可以在金屬上鑲嵌皮革、橡膠、或者采用合成覆蓋面，這取決于使用性能的要求。旋啟式止回閥在完全打開(kāi)的狀況下，其流體壓力幾乎不受阻礙，因此通過(guò)閥門(mén)的壓力降相對(duì)較小。電站止回閥介質(zhì)倒流的原因有1、密封面破壞；2、夾入雜質(zhì)。安徽自密封升降止回閥廠家</p><p
