產(chǎn)品詳情
按閥桿的螺紋位置劃分,可分為明桿閘閥和暗桿閘閥兩種。閘閥的安裝與維護應(yīng)注意以下事項:手輪、手柄及傳動機構(gòu)均不允許作起吊用,并嚴禁碰撞。雙閘板閘閥應(yīng)垂直安裝(即閥桿處于垂直位置,手輪在頂部)。帶有旁通閥的閘閥在開啟前應(yīng)先打開旁通閥(以平衡進出口的壓差及減小開啟力)。帶傳動機構(gòu)的閘閥,按產(chǎn)品使用說明書的規(guī)定安裝。如果閥門經(jīng)常開關(guān)使用,每月至少潤滑一次。結(jié)構(gòu)特點:長期以來市場上使用的一般閘閥普遍存在著漏水或生銹現(xiàn)象,本企業(yè)引進歐洲高科技橡膠及閥門制造技術(shù)所生產(chǎn)的彈性座封閘閥,克服了一般閘閥密封不良,生銹等缺陷,彈性座封閘閥利用彈性閘板產(chǎn)生微量彈性變形的補償作用達到良好的密封效果,該閥具有開關(guān)輕巧、密封可靠、彈性記憶佳及使用壽命等顯著優(yōu)點。

可以說我國的機械生產(chǎn)已滿足了國內(nèi)的基本需求,并開始向東南亞及第三世界出口,如我國2年的進出口總額為27.37億美元,其中出口額為12.9億美元,比1999年提高了22.2%。在出口的機械品種中以食品(乳品、糕點、肉類、水果)加工機、烤箱、封裝、貼標簽機、紙塑鋁復(fù)合罐生產(chǎn)設(shè)備等機械出口較多,食品機械如制糖、釀酒、飲料、真空包裝機等設(shè)備已開始成套出口。現(xiàn)今常用、基本的包裝工藝方法有兩大類,即充填與裹包。

原因水質(zhì)差含顆粒。由于水質(zhì)差,含有小顆粒及介質(zhì)中鹽酸鹽含量高,形成磨料磨損機封的平面或拉傷表面產(chǎn)生溝槽、環(huán)溝等現(xiàn)象。處理辦法:改進水壓或介質(zhì),更換機封。原因缺水運行造成干磨損壞。此現(xiàn)象多見于底閥式安裝形式進口處負壓,進水管有空氣,泵腔內(nèi)有空氣,泵開機后,機封的磨擦高速運轉(zhuǎn)時產(chǎn)生高溫,無法得到冷卻,檢查機封,彈簧張力正常,摩擦面燒焦發(fā)黑,橡膠變硬開裂。處理辦法:排盡管道及泵腔內(nèi)空氣,更換機械密封。
