密封面不易磨損及擦傷，密封性好，啟閉時閥瓣與閥體密封面之間無相對滑動，因而磨損與擦傷均不嚴(yán)重，密封性能好，使用壽命長。 </p> <p> 啟閉時，閥瓣行程小，因而截止閥高度比閘閥小，但結(jié)構(gòu)長度比閘閥長。 </p> <p> 啟閉力矩大、啟閉較費力，啟閉時間校長。 </p> <p> 流體阻力大，因閥體內(nèi)介質(zhì)通道較曲折，流體阻力大，動力消耗大。 </p> <p> 介質(zhì)流動方向公稱壓力PN≤16MPa時，一般采用順流，介質(zhì)從閥瓣下方向上流；公稱壓力PN≥20MPa時，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，截止閥介質(zhì)只能單方向流動，不能改變流動方向。上海不銹鋼閘閥來電咨詢不銹鋼閘閥耐腐制造。</p><div style="width:100%;text-align: center;"><img

通常情況下，如果把不銹鋼閥門放在相對干燥的環(huán)境中，經(jīng)過很長時間，閥門不僅完好如新，而且也沒有上銹。 </p> <p> 而如果把閥門放置于含有大量鹽分的海水中，沒有幾天就會生銹。因此，不銹鋼閥門的耐腐蝕性和不銹鋼性也需要根據(jù)環(huán)境來衡量。 </p> <p> “從不銹鋼閥門的本身特性來看，之所以不銹是因為在其表面有一層富鉻氧化膜來防止外界的氧原子等粒子對物件造成侵襲損害，從而使閥門具有不銹的特性?！?*表示，不過，當(dāng)這種膜受到環(huán)境等因素的破壞后，會隨著氧原子進(jìn)入，與鐵離子游離出來，不銹鋼閥門就生銹了。 </p> <p> <br /> </p><p> 要經(jīng)常對不銹鋼閥門表面進(jìn)行清潔擦洗，去除附著物，消除引發(fā)銹蝕的外界因素。 </p> <p> 第二，海濱地區(qū)要使用316材質(zhì)的不銹鋼，因為316材質(zhì)能抵抗海水的腐蝕。 </p> <p> 第三，市場上有些不銹鋼管化學(xué)成分不符合相應(yīng)的國家標(biāo)準(zhǔn)，達(dá)不到304的材質(zhì)要求，因此也會引起生銹。對此，技術(shù)人員表示，用戶在選擇不銹鋼閥門之時，一定要認(rèn)真選擇有信譽廠家的產(chǎn)品。般德不銹鋼閥門，材質(zhì)優(yōu)，品質(zhì)好，是您的信賴之選~ </p> <p>

電動不銹鋼閘閥簡單地說就是用電動執(zhí)行器控制的閘閥,電動不銹鋼閘閥主要有兩種，一種為角行程電動不銹鋼閘閥：由角行程的電動執(zhí)行器配合角行程的閥使用，實現(xiàn)閘閥90度以內(nèi)旋控制管道流體通斷；另一種為直行程電動不銹鋼閘閥：由直行程的電動執(zhí)行器配合直行程的閥使用，實現(xiàn)閥板上下動作控制管道流體通斷。通常在自動化程度較高的設(shè)備上配套使用,本閥水平按裝調(diào)節(jié)精度極好。電動不銹鋼閘閥通常由電動執(zhí)行機構(gòu)和閥門連接起來，經(jīng)過安裝調(diào)試后成為電動閥。電動不銹鋼閘閥使用電能作為動力來接通電動執(zhí)行機構(gòu)驅(qū)動閥門，實現(xiàn)閥門的開關(guān)、調(diào)節(jié)動作。從而達(dá)到對管道介質(zhì)的開關(guān)或是調(diào)節(jié)目的。</span>
