<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，甘肅預(yù)作用報(bào)警閥門直銷，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，甘肅預(yù)作用報(bào)警閥門直銷，甘肅預(yù)作用報(bào)警閥門直銷，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。甘肅預(yù)作用報(bào)警閥門直銷</p><div style="width:100%;text-align: center;"><img

七、內(nèi)自緊連接： </p> <p> 以上各種連接形式，都是利用外力來抵消介質(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。甘肅溝槽閥門供應(yīng)</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

按驅(qū)動(dòng)方式分類分為自動(dòng)閥類、動(dòng)力驅(qū)動(dòng)閥類和手動(dòng)閥類： </p> <p> (1) 自動(dòng)閥是指不需要外力驅(qū)動(dòng)，而是依靠介質(zhì)自身的能量來使閥門動(dòng)作的閥門。如安全閥、減壓閥、疏水閥、止回閥、自動(dòng)調(diào)節(jié)閥等。 </p> <p> (2) 動(dòng)力驅(qū)動(dòng)閥：動(dòng)力驅(qū)動(dòng)閥可以利用各種動(dòng)力源進(jìn)行驅(qū)動(dòng)。分為電動(dòng)閥、氣動(dòng)閥、液動(dòng)閥等。電動(dòng)閥：借助電力驅(qū)動(dòng)的閥門。氣動(dòng)閥：借助壓縮空氣驅(qū)動(dòng)的閥門。液動(dòng)閥：借助油等液體壓力驅(qū)動(dòng)的閥門。 </p> <p> 此外還有以上幾種驅(qū)動(dòng)方式的組合，如氣-電動(dòng)閥等。 </p> <p> (3) 手動(dòng)閥：手動(dòng)閥借助手輪、手柄、杠桿、鏈輪，由人力來操縱閥門動(dòng)作。當(dāng)閥門啟閉力矩較大時(shí)，可在手輪和閥桿之間設(shè)置齒輪或蝸輪減速器。必要時(shí)，也可以利用萬向接頭及傳動(dòng)軸進(jìn)行遠(yuǎn)距離操作。 </p><p> 分類 </p> <p> 折疊按作用和用途分類 </p> <p> （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><div
