style="font-size:12px;">不銹鋼閘閥有多種類別，按密封面配置可分為楔式閘板式不銹鋼閘閥和平行閘板式不銹鋼閘閥，楔式閘板式不銹鋼閘閥又可分為單閘極式、雙閘板式和彈性閘板式；平行閘板式閘閥可分為單閘板式和雙閘板式。按閥桿的螺紋位置劃分，可分為明桿不銹鋼閘閥和暗桿不銹鋼閘閥兩種。不銹鋼閘閥特別適合于高粘度產(chǎn)品，低雷諾數(shù)量，帶懸浮顆粒，給氣泡介質(zhì)測(cè)量，根據(jù)精度不受流體介質(zhì)電常數(shù)特性的影響和限制。結(jié)構(gòu)設(shè)計(jì)特殊，有導(dǎo)流作用，防止堵塞的情況是詳細(xì)資料場(chǎng)合有無比擬的一種替代品作用。</span> </p> <p> <br /> </p> <p> <br /> </p><p> 安全閥結(jié)構(gòu)主要有兩大類：彈簧式和杠桿式。彈簧式是指閥瓣與閥座的密封靠彈簧的作用力。杠桿式是靠杠桿和重錘的作用力。隨著大容量的需要，又有一種脈沖式安全閥，也稱為先導(dǎo)式安全閥，由主安全閥和輔助閥組成。當(dāng)管道內(nèi)介質(zhì)壓力超過規(guī)定壓力值時(shí)，輔助閥先開啟，介質(zhì)沿著導(dǎo)管進(jìn)入主安全閥，并將主安全閥打開，使增高的介質(zhì)壓力降低。 </p> <p> 安全閥的排放量決定于閥座的口徑與閥瓣的開啟高度，也可分為兩種：微啟式開啟高度是閥座內(nèi)徑的（1/20）～（1/40），全啟式是（1/3）～（1/4）。 </p> <p> <br /> 耐腐供應(yīng)生產(chǎn)不銹鋼閘閥。</p><div style="width:100%;text-align: center;"><img style="max-width:

(1)結(jié)構(gòu)比閘閥簡(jiǎn)單，制造與維修都較方便。 </p> <p> (2)密封面不易磨損及擦傷，密封性好，啟閉時(shí)閥瓣與閥體密封面之間無相對(duì)滑動(dòng)，因而磨損與擦傷均不嚴(yán)重，密封性能好，使用壽命長(zhǎng)。 </p> <p> (3)啟閉時(shí)，閥瓣行程小，因而截止閥高度比閘閥小，但結(jié)構(gòu)長(zhǎng)度比閘閥長(zhǎng)。 </p> <p> (4)啟閉力矩大、啟閉較費(fèi)力，啟閉時(shí)間校長(zhǎng)。 </p> <p> (5)流體阻力大，因閥體內(nèi)介質(zhì)通道較曲折，流體阻力大，動(dòng)力消耗大。 </p> <p> (6)介質(zhì)流動(dòng)方向公稱壓力PN≤16MPa時(shí)，一般采用順流，介質(zhì)從閥瓣下方向上流；公稱壓力PN≥20MPa時(shí)，一般采用逆流，介質(zhì)從閥瓣上方向．以增加密封件能。使用時(shí)，截止閥介質(zhì)只能單方向流動(dòng)，不能改變流動(dòng)方向。 </p> <p> <br /> </p> <p> <br />
