既按原理、作用又按結(jié)構(gòu)劃分，是目前國(guó)際、國(guó)內(nèi)**常用的分類方法。一般分閘閥、截止閥、節(jié)流閥、儀表閥、柱塞閥、隔膜閥、旋塞閥、球閥、蝶閥，安徽軟密封閘閥門供應(yīng)、止回閥、減壓閥安全閥、疏水閥、調(diào)節(jié)閥、底閥、過濾器、排污閥等。 </p> <p> 由于閥門的用途是非常廣的，因此它起的作用也是很大的。例如：在發(fā)電廠中閥門能夠控制鍋爐和汽輪機(jī)的運(yùn)轉(zhuǎn)；在石油、化工生產(chǎn)中，安徽軟密封閘閥門供應(yīng)，閥門同樣也起著控制全部生產(chǎn)設(shè)備和工藝流程的正常運(yùn)轉(zhuǎn)。在其它部門也是這樣。盡管如此，閥門同其它產(chǎn)品比較往往被人們忽視。例如：在安裝機(jī)器設(shè)備時(shí)，人們往往把重點(diǎn)放在主要機(jī)器設(shè)備方面，卻忽視了閥門。這樣會(huì)使整個(gè)生產(chǎn)效率降低或停產(chǎn)、或造成種種其它事件發(fā)生。因此，安徽軟密封閘閥門供應(yīng)，對(duì)閥門的選用、安裝、使用等都必須進(jìn)行認(rèn)真負(fù)責(zé)的工作。安徽軟密封閘閥門供應(yīng)</p><div

以上各種連接形式，都是利用外力來(lái)抵消介質(zhì)壓力，實(shí)現(xiàn)密封的。下面介紹利用介質(zhì)壓力進(jìn)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(gè)分力，一個(gè)與閥體中心線平行向外，另一個(gè)壓向閥體內(nèi)壁。后面這個(gè)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(shí)，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(duì)待。 </p><p> 五、卡套連接： </p> <p> 卡套連接，在中國(guó)近年才發(fā)展起來(lái)，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><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="安徽軟密封閘閥門供應(yīng),閥門"

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。用于工作壓力≥100公斤/平方厘米的高壓閥門，或高溫閥門。 </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(lái)的，它在密封效果上比一般平墊圈可靠。江蘇止回閥門便宜</p><p style="text-indent:25px">安徽軟密封閘閥門供應(yīng)</p><p
