1、重量輕：本體采用高質(zhì)量球黑鑄鐵制成，重量較傳統(tǒng)閘閥重量減輕約 20%~30%，安裝維修方便。 2、整體包膠：閘板采用***的橡膠進(jìn)行整體內(nèi)、外包膠，歐洲橡膠硫化技術(shù)使得硫化后的閘板能夠保證精確的幾何尺寸，且橡膠與球墨鑄閘板接著牢靠，不易脫落及彈性記憶佳。 3、平底式閘座：傳統(tǒng)的閘閥往往在通水洗管后即因外物諸如石頭，木塊、水泥、鐵屑、雜物等淤積于閥底凹槽內(nèi)，容易造成無(wú)法關(guān)閉緊密而形成漏水現(xiàn)象，彈性座封閘閥底部采用與水管機(jī)同的平底設(shè)計(jì)，不易造成雜物淤積，使流體暢通無(wú)阻。 4、精鑄閥體：閥體采用精密鑄造，精確的幾何尺寸使得閥體內(nèi)部無(wú)需任何精加工即可保證閥門的密封性。美國(guó)紐曼蒂克電磁閥價(jià)格閥門的材質(zhì)那么多，我們應(yīng)該怎么挑選？</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

style="text-indent:25px">在眾多的閥門產(chǎn)品中，閘閥和蝶閥都是很是常用的閥門型號(hào)。然而，很多用戶在選型時(shí)因不知道閘閥和蝶閥的區(qū)別是什么，而不知道如何選擇這兩種閥門。其實(shí)吧，從定義上區(qū)分；閘閥是一種較為常見(jiàn)的啟閉閥，利用閘板(即啟閉件，在閘板中啟閉件稱為閘板或閘門，閘座稱為閘板座)來(lái)接通(全開(kāi))或截?cái)?全關(guān))管路中的介質(zhì)。它不允許作為截流用，使用中應(yīng)避免將閘板微量開(kāi)啟，因高速流動(dòng)的介質(zhì)的沖蝕會(huì)加速密封面的損壞。閘板在垂直于閘門座通道中心線的片面作為升降運(yùn)動(dòng)，像閘門一樣截?cái)喙苈分械慕橘|(zhì)，故稱做閘閥。而蝶閥是指關(guān)閉件(閥瓣或蝶板)為圓盤，圍繞閥軸旋轉(zhuǎn)來(lái)達(dá)到開(kāi)啟與關(guān)閉的一種閥，在管道上主要起切斷和節(jié)流用。蝶閥啟閉件是一個(gè)圓盤形的蝶板，在閥體內(nèi)繞其自身的軸線旋轉(zhuǎn)，從而達(dá)到啟閉或調(diào)節(jié)的目的。蝶閥全開(kāi)到全關(guān)通常是小于90°，蝶閥和蝶桿本身沒(méi)有自鎖能力，為了蝶板的定位，要在閥桿上加裝蝸輪減速器。采用蝸輪減速器，不僅可以使蝶板具有自鎖能力，使蝶板停止在任意位置上，還能改善閥門的操作性能。</p><p style="text-indent:25px">氣動(dòng)主要是用與切斷以及流通管路中流體介質(zhì)的，能夠準(zhǔn)確的對(duì)流體介質(zhì)進(jìn)行調(diào)節(jié)閥和控制。氣動(dòng)閥有很多種類常見(jiàn)的有氣動(dòng)調(diào)節(jié)閥、氣動(dòng)隔膜閥、氣動(dòng)電磁閥、氣動(dòng)截止閥、氣動(dòng)角座閥、氣動(dòng)電磁閥、氣動(dòng)換向閥、氣動(dòng)減壓閥、氣動(dòng)截止閥、氣動(dòng)閘板閥等等，種類非常之多。那么用戶在采購(gòu)的時(shí)候往往會(huì)詢問(wèn)廠商價(jià)格，其實(shí)就價(jià)格而言不通類型的氣動(dòng)閥價(jià)格是有差異的，這其中包括動(dòng)作方式的不同和閥體材質(zhì)的不同，其價(jià)格都是不一樣的。哪一種的閥門比較好？</p><div

①明桿閘閥：閥桿螺母在閥蓋或支架上，開(kāi)閉閘板時(shí)，用旋轉(zhuǎn)閥桿螺母來(lái)實(shí)現(xiàn)閥桿的升降。這種結(jié)構(gòu)對(duì)閥桿的潤(rùn)滑有利，開(kāi)閉程度明顯，因此被大范圍采用。 ②暗桿閘閥：閥桿螺母在閥體內(nèi)，與介質(zhì)直接接觸。開(kāi)閉閘板時(shí)，用旋轉(zhuǎn)閥桿來(lái)實(shí)現(xiàn)。這種結(jié)構(gòu)的優(yōu)點(diǎn)是：閘閥的高度總保持不變，因此安裝空間小，適用于大口徑或?qū)Π惭b空間受限制的閘閥。其兩個(gè)主要區(qū)別是：暗桿法蘭閘閥的提升螺桿是只旋轉(zhuǎn)而無(wú)上和下移動(dòng)，外露的只是一根桿，其螺母是固定在閘板上，通過(guò)螺桿的旋轉(zhuǎn)來(lái)提升閘板，沒(méi)有可見(jiàn)的門架；明桿法蘭閘閥的提升螺桿是外露的，螺母緊貼手輪且是固定的（不旋轉(zhuǎn)也不軸向移動(dòng)），通過(guò)旋轉(zhuǎn)螺桿來(lái)提升閘板，螺桿與閘板只有相對(duì)的旋轉(zhuǎn)運(yùn)動(dòng)而無(wú)相對(duì)的軸向位移，外觀為有門形支架。暗桿閥門就是看不見(jiàn)絲杠，而明桿的就是能看見(jiàn)絲桿的。說(shuō)簡(jiǎn)單點(diǎn)就是明桿閥門是閥瓣連著閥桿一起做上下運(yùn)動(dòng)，方向盤始終在固定點(diǎn)。關(guān)于閥門的知識(shí)你了解多少？美國(guó)紐曼蒂克電磁閥價(jià)格</p><p

style="text-indent:25px">如何正確安裝減壓閥？（1）減壓閥的安裝應(yīng)在供水管網(wǎng)試壓、沖洗合格后進(jìn)行，檢查管道試壓及沖洗記錄。（2）減壓閥安裝前應(yīng)檢查其規(guī)格型號(hào)應(yīng)與設(shè)計(jì)相符、閥外控制管路及導(dǎo)向閥各連接件不應(yīng)有松動(dòng)、外觀應(yīng)無(wú)機(jī)械損傷，并應(yīng)去除閥內(nèi)異物。（3）為了操作和維護(hù)方便，減壓閥一般直立安裝在水平管道上。比例式減壓閥宜垂直安裝，當(dāng)水平安裝時(shí)單呼吸孔減壓閥其孔口應(yīng)向下，雙呼吸孔減壓閥其孔口應(yīng)呈水平位置；可調(diào)式減壓閥宜水平安裝，閥蓋應(yīng)向上。（4）減壓閥安裝必須嚴(yán)格按照閥體上的箭頭方向保持和流體流動(dòng)方向一致。如果水質(zhì)不清潔含有一些雜質(zhì)，必須在減壓閥的上游進(jìn)水口安裝過(guò)濾器（我們建議過(guò)濾精度不低于0.5mm）。（5）應(yīng)在進(jìn)水側(cè)安裝過(guò)濾器，并宜在其前后安裝控制閥。（6）為了防止閥后壓力超壓，應(yīng)在離閥出口不少于4M處安裝一個(gè)減壓閥。如果需要將減壓閥安裝在熱水系統(tǒng)時(shí)，您必須在減壓閥和膨脹水箱之間安裝止回閥。這樣既可以讓膨脹水箱吸收由于熱膨脹而增加的水的體積，又可以防止熱水回流或壓力波動(dòng)對(duì)減壓閥的影響，確保減壓閥長(zhǎng)期正常工作。美國(guó)紐曼蒂克電磁閥價(jià)格</p><p
