其耐蝕性也不相同。塑料襯里的耐蝕性與上述塑料閥門中的相應(yīng)塑料相同。但選用時(shí)，應(yīng)考慮塑料襯里閥門中使用的其它材料的耐蝕性能。⑽橡膠襯里閥門橡膠較軟，因此很多閥門采用橡膠做襯里，以提高閥門的抗蝕性能和密封性能。隨橡膠種類的不同，其耐蝕性差異較大。經(jīng)過硫化的天然橡膠能耐非氧化性酸、堿、鹽的腐蝕，但不耐強(qiáng)氧化劑，如硝酸、鉻酸、濃***的腐蝕，也不耐石油產(chǎn)品和某些有機(jī)溶劑的腐蝕。因此，博樂低壓閥門大全，天然橡膠被合成橡膠逐漸代替。合成橡膠中的丁腈橡膠耐油性能好，但不耐氧化性酸、芳烴、脂、酮、醚等強(qiáng)溶劑的腐蝕；氟橡膠耐蝕性能優(yōu)異，能耐各類酸、堿、鹽、石油產(chǎn)品、烴類等，但耐溶劑性不及氟塑料；聚醚橡膠可用于水、油、氨、堿等介質(zhì)。⑾鉛襯里閥門鉛屬活性金屬，但因材質(zhì)軟，常用作特殊閥門的襯里。鉛的腐蝕產(chǎn)物膜是很強(qiáng)的保護(hù)層，博樂低壓閥門大全，它是耐***的有名材料，在磷酸、鉻酸、碳酸及中性溶液、海水等介質(zhì)中具有較高的耐蝕性能、但不耐堿、鹽酸的腐蝕，也不適于在它們的腐蝕產(chǎn)物中工作。四、根據(jù)溫度和壓力選用閥門返回頁優(yōu)先用閥門除了考慮介質(zhì)的腐蝕性能、流量特性，博樂低壓閥門大全、連接形式外，介質(zhì)的溫度和壓力是重要的參數(shù)。博樂消聲止回閥廠家。博樂低壓閥門大全</p><div

一、根據(jù)流量特性選用閥門閥門啟閉件及閥門流道的形狀使閥門具備一定的流量特性。在選擇閥門時(shí)，必須考慮到這一點(diǎn)。1.截?cái)嗪徒油ń橘|(zhì)用閥門通常選擇流阻較小、流道為直通式的閥門。這類閥門有閘閥、截止閥、柱塞閥。向下閉合式閥門，由于流道曲折，流阻比其它閥門高，故較少選用。但是，在允許有較高流阻的場合，也可選用閉合式閥門。2.控制流量用的閥門通常選擇易于調(diào)節(jié)流量的閥門。如調(diào)節(jié)閥、節(jié)流閥、柱塞閥，因?yàn)樗拈y座尺寸與啟閉件的行程之間成正比例關(guān)系。旋轉(zhuǎn)式（如旋塞閥、球閥、蝶閥）和撓曲閥體式（夾管閥、隔膜閥）閥門也可用于節(jié)流控制，但通常*在有限的閥門口徑范圍內(nèi)適用。在多數(shù)情況下，人們通常采用改變截止閥的閥瓣形狀后作節(jié)流用。應(yīng)該指出，用改變閘閥或截止閥的開啟高度來實(shí)現(xiàn)節(jié)流作用是極不合理的。因?yàn)椋苈分薪橘|(zhì)在節(jié)流狀態(tài)***速很高，密封面容易被沖刷磨損，失去切斷密封作用，同理，用節(jié)流閥作為切斷裝置也是不合理的。3.換向分流用閥門根據(jù)換向分流需要，這種閥可有三個(gè)或者更多的通道，適宜于選用旋塞閥和球閥。大部分換向分流用的閥門都選用這類閥門。在某些情況下，其它類型的閥門，用兩只或更多只適當(dāng)?shù)叵嗷ミB接起來。</p><p style="text-indent:25px">當(dāng)壓力略低于正常工作壓力時(shí)，安全閥自動(dòng)關(guān)閉，停止排放流體并保持密封。泄壓閥主要是用在壓力過大的場合，當(dāng)壓力大于設(shè)定值時(shí)閥內(nèi)片被頂開及時(shí)釋放壓力，壓力減小后恢復(fù)到原來的位置，和安全閥區(qū)別不大，泄壓閥多指用于液體的，安全閥多指用于氣體，蒸汽的。穩(wěn)壓閥是將一個(gè)區(qū)域內(nèi)的介質(zhì)保持在一定的壓力范圍的設(shè)備。和減壓閥的區(qū)別：減壓閥：無論進(jìn)口壓力如何變化，都把出口壓力減到額定值，起到減壓作用。穩(wěn)壓閥：無論下游壓力和需求量如何變化，都維持一個(gè)恒定的上游壓力。安全閥及減壓閥是兩種閥門類型，是**閥門。其中，安全閥屬于安全泄發(fā)裝置，是**閥門，只在工作壓力超過允許范圍時(shí)動(dòng)作，對系統(tǒng)起到保護(hù)作用。減壓閥屬于工藝閥門，可使高壓物流減壓，以滿足后系統(tǒng)對壓力的要求，其工作過程是連續(xù)的。阿克蘇閘閥廠家。。。</p><div
