class="title">詳細說明</p><div id="e8t3kzr" class="box"><p><p> 五、卡套連接： </p> <p> 卡套連接，在中國近年才發(fā)展起來，它的連接和密封原理是，當旋緊螺母時，卡套受到壓力，使其刃部咬入管子外壁，卡套外錐面又在壓力下與接頭體內(nèi)錐面密合，浙江止回閥門供應(yīng)，因而能夠可靠地防止泄漏。 </p> <p> 這種連接形式的優(yōu)點是： </p> <p> 1、體積小，重量輕，結(jié)構(gòu)簡單，拆裝容易； </p> <p> 2、連接力強，使用范圍廣，可耐高壓（1000公斤/平方厘米）、高溫（650℃）和沖擊振動 </p> <p> 3、可以選用多種材料，適合防腐蝕； </p> <p> 4、加工精度要求不高；便于高空安裝。 </p> <p> 目前，卡套連接形式，浙江止回閥門供應(yīng)，已在中國某些小口徑閥門產(chǎn)品中采用。 </p> <p> 六，浙江止回閥門供應(yīng)、卡箍連接： </p> <p> 這是一種快速連接方法，它只需兩個螺栓，適用于經(jīng)常拆卸的低壓閥門。浙江止回閥門供應(yīng)</p><div style="width:100%;text-align: center;"><img

折疊按作用和用途分類 </p> <p> （1）截斷類：如閘閥、截止閥、旋塞閥、球閥、蝶閥、針型閥、隔膜閥等。截斷類閥門又稱閉路閥，截止閥，其作用是接通或截斷管路中的介質(zhì)。 </p> <p> (2) 止回類：如止回閥，止回閥又稱單向閥或逆止閥，止回閥屬于一種自動閥門，其作用是防止管路中的介質(zhì)倒流、防止泵及驅(qū)動電機反轉(zhuǎn)，以及容器介質(zhì)的泄漏。水泵吸水關(guān)的底閥也屬于止回閥類。 </p> <p> (3) 安全類：如安全閥、防爆閥等。安全閥的作用是防止管路或裝置中的介質(zhì)壓力超過規(guī)定數(shù)值，從而達到安全保護的目的。 </p> <p> (4) 調(diào)節(jié)類：如調(diào)節(jié)閥、節(jié)流閥和減壓閥，其作用是調(diào)節(jié)介質(zhì)的壓力、流量等參數(shù)。 </p> <p> (5) 分流類：如分配閥、三通閥、疏水閥。其作用是分配、分離或混合管路中的介質(zhì)。 </p> <p> (6）特殊用途類：如清管閥、放空閥、排污閥、排氣閥、過濾器等。排氣閥是管道系統(tǒng)中必不可少的輔助元件，廣泛應(yīng)用于鍋爐、空調(diào)、石油天然氣、給排水管道中。往往安裝在制高點或彎頭等處，排除管道中多余氣體、提高管道路使用效率及降低能耗。浙江閘閥門全國發(fā)貨</p><div style="width:100%;text-align: center;"><img

密封性能要求 </p> <p> 閥門的密封性能是指閥門各密封部位阻止介質(zhì)泄漏的能力，它是閥門**重要的技術(shù)性能指標。閥門的密封部位有三處：啟閉件與閥座兩密封面間的接觸處；填料與閥桿和填料函的配合處；閥體與閥蓋的連接處。其中前一處的泄漏叫做內(nèi)漏，也就是通常所說的關(guān)不嚴，它將影響閥門截斷介質(zhì)的能力。對于截斷閥類來說，內(nèi)漏是不允許的。后兩處的泄漏叫做外漏，即介質(zhì)從閥內(nèi)泄漏到閥外。外漏會造成物料損失，污染環(huán)境，嚴重時還會造成惡事件。對于易燃易爆、或有放射的介質(zhì)，外漏更是不能允許的，因而閥門必須具有可靠的密封性能。

閥門是用來開閉管路、控制流向、調(diào)節(jié)和控制輸送介質(zhì)的參數(shù)（溫度、壓力和流量）的管路附件。根據(jù)其功能，可分為關(guān)斷閥、止回閥、調(diào)節(jié)閥等。閥門是流體輸送系統(tǒng)中的控制部件，具有截止、調(diào)節(jié)、導(dǎo)流、防止逆流、穩(wěn)壓、分流或溢流泄壓等功能。用于流體控制系統(tǒng)的閥門，從**簡單的截止閥到極為復(fù)雜的自控系統(tǒng)中所用的各種閥門，其品種和規(guī)格相當繁多。閥門可用于控制空氣、水、蒸汽、各種腐蝕性介質(zhì)、泥漿、油品、液態(tài)金屬和放射性介質(zhì)等各種類型流體的流動。閥門根據(jù)材質(zhì)還分為鑄鐵閥門，鑄鋼閥門，不銹鋼閥門（201、304、316等），鉻鉬鋼閥門，鉻鉬釩鋼閥門，雙相鋼閥門，塑料閥門，非標訂制閥門等。浙江止回閥門供應(yīng)</p><p style="text-indent:25px">浙江止回閥門供應(yīng)</p><p> 七、內(nèi)自緊連接： </p> <p> 以上各種連接形式，都是利用外力來抵消介質(zhì)壓力，實現(xiàn)密封的。下面介紹利用介質(zhì)壓力進行自緊的連接形式。它的密封圈裝在內(nèi)錐體處，跟介質(zhì)相向的一面成一定角度，介質(zhì)壓力傳給內(nèi)錐體，又傳遞給密封圈，在一定角度的錐面上，產(chǎn)生兩個分力，一個與閥體中心線平行向外，另一個壓向閥體內(nèi)壁。后面這個分力便是自緊力。介質(zhì)壓力愈大，自緊力也愈大。所以這種連接形式，適合于高壓閥門。它比法蘭連接，要節(jié)省許多材料和人力，但也需要一定的預(yù)緊力，以便在閥內(nèi)壓力不高時，使用可靠。利用自緊密封原理做成的閥門，一般是高壓閥門。 </p> <p> 閥門連接的形式還很多，例如有的不必拆除的小閥門，跟管子焊接在一起；有的非金屬閥門，采用承插式連接，等等。閥門使用者要根據(jù)具休情況具體對待。浙江止回閥門供應(yīng)</p><p
