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(mén)。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(mén)，一般是高壓閥門(mén)。 </p> <p> 閥門(mén)連接的形式還很多，例如有的不必拆除的小閥門(mén)，跟管子焊接在一起；有的非金屬閥門(mén)，采用承插式連接，等等。閥門(mén)使用者要根據(jù)具休情況具體對(duì)待。江蘇橡膠軟接頭閥門(mén)零售</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

折疊按作用和用途分類(lèi) </p> <p> （1）截?cái)囝?lèi)：如閘閥、截止閥、旋塞閥、球閥、蝶閥、針型閥、隔膜閥等。截?cái)囝?lèi)閥門(mén)又稱(chēng)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(lèi)：如止回閥，止回閥又稱(chēng)單向閥或逆止閥，止回閥屬于一種自動(dòng)閥門(mén)，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(lèi)。 </p> <p> (3) 安全類(lèi)：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(guò)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(lèi)：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(lèi)：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(lèi)：如清管閥、放空閥、排污閥、排氣閥、過(guò)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> 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(mén)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(mén)。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="安徽品牌閥門(mén)零售價(jià)格,閥門(mén)"

</p> <p> 1、光滑式：用于壓力不高的閥門(mén)。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(mén)，或高溫閥門(mén)。 </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(mén)，或高溫閥門(mén)。 </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。江蘇正規(guī)閥門(mén)哪家好</p><p
