class="title">詳細(xì)說明</p><div id="3e2lcev" 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(dāng)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，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），甘肅安全閥門便宜、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，甘肅安全閥門便宜。 </p> <p> 目前，卡套連接形式，已在中國某些小口徑閥門產(chǎn)品中采用。 </p> <p> 六，甘肅安全閥門便宜、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。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="甘肅安全閥門便宜" src="http://tyunfile.71360.com/UpLoadFile/sdkgfm/2019/11/637087466181411099/6370874661814110993100538.png"></div><p> 閥門介紹 </p> <p> 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(dāng)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(biāo)訂制閥門等。

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。 </p></p><br /><p>文章來源地址: http://m.cdcfah.com/cp/372038.html</p></div></div></div></div></div><div id="f3phjl2"
