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。甘肅預(yù)作用報(bào)警閥門全國(guó)發(fā)貨</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

（1）截?cái)囝悾喝玳l閥、截止閥、旋塞閥、球閥、蝶閥、針型閥、隔膜閥等。截?cái)囝愰y門又稱閉路閥，截止閥，其作用是接通或截?cái)喙苈分械慕橘|(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(dòng)閥門，其作用是防止管路中的介質(zhì)倒流、防止泵及驅(qū)動(dòng)電機(jī)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(dá)到安全保護(hù)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(diǎn)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。 </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。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。

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、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，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，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。甘肅預(yù)作用報(bào)警閥門全國(guó)發(fā)貨</p><p
