class="title">詳細(xì)說明</p><div id="xnpgrne" class="box"><p><p> 閥門連接方式 </p> <p> 一、法蘭連接： </p> <p> 這是閥門中用得**多的連接形式。按結(jié)合面形狀又可分為以下幾種： </p> <p> 1、光滑式：用于壓力不高的閥門。加工比較方便 </p> <p> 2、凹凸式：工作壓力較高，可使用中硬墊圈 </p> <p> 3、榫槽式：可用塑性變形較大的墊圈，在腐蝕性介質(zhì)中使用較廣，密封效果較好。 </p> <p> 4、梯形槽式：用橢圓形金屬環(huán)作墊圈，使用于工作壓力≥64公斤/平方厘米的閥門，或高溫閥門。 </p> <p> 5、透鏡式：墊圈是透鏡形狀，用金屬制作，江蘇安全閥門便宜。用于工作壓力≥100公斤/平方厘米的高壓閥門，江蘇安全閥門便宜，或高溫閥門，江蘇安全閥門便宜。 </p> <p> 6、O形圈式：這是一種較新的法蘭連接形式，它是隨著各種橡膠O形圈的出現(xiàn)，而發(fā)展起來的，它在密封效果上比一般平墊圈可靠。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="江蘇安全閥門便宜" src="http://tyunfile.71360.com/UpLoadFile/sdkgfm/2019/11/637087465943431242/6370874659434312425065709.png"></div><p> 二、對(duì)夾連接： </p> <p> 用螺栓直接將閥門及兩頭管道穿夾在一起的連接形式。 </p> <p> 三、對(duì)焊連接： </p> <p> 直接與管道焊接的連接形式。 </p> <p> 四、螺紋連接： </p> <p> 這是一種簡(jiǎn)便的連接方法，常用于小閥門。又分兩種情況： </p> <p> 1、直接密封：內(nèi)外螺紋直接起密封作用。為了確保連接處不漏，往往用鉛油、線麻和聚四氟乙烯生料帶填充；其中聚四氟乙烯生料帶，使用日見廣；這種材料耐腐蝕性能很好，密封效果較好，使用和保存方便，拆卸時(shí)，可以完整地將其取下，因?yàn)樗且粚訜o粘性的薄膜，比鉛油、線麻優(yōu)越得多。 </p> <p> 2、間接密封：螺紋旋緊的力量，傳遞給兩平面間的墊圈，讓墊圈起密封作用。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="江蘇安全閥門便宜" src="http://tyunfile.71360.com/UpLoadFile/sdkgfm/2019/11/637087466351188920/6370874663511889202692772.png"></div><p> 五、卡套連接： </p> <p> 卡套連接，在中國(guó)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(shí)，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(diǎn)是： </p> <p> 1、體積小，重量輕，結(jié)構(gòu)簡(jiǎn)單，拆裝容易； </p> <p> 2、連接力強(qiáng)，使用范圍廣，可耐高壓（1000公斤/平方厘米）、高溫（650℃）和沖擊振動(dòng) </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，已在中國(guó)某些小口徑閥門產(chǎn)品中采用。 </p> <p> 六、卡箍連接： </p> <p> 這是一種快速連接方法，它只需兩個(gè)螺栓，適用于經(jīng)常拆卸的低壓閥門。 </p></p><br /><p>文章來源地址: http://m.cdcfah.com/cp/304945.html</p></div></div></div></div></div><div id="o3hykqm" class="page-right twoColRt"><div id="pyulcye"
