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，浙江水利閥門零售價(jià)格。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，浙江水利閥門零售價(jià)格。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。浙江水利閥門零售價(jià)格</p><div

卡套連接，在中國近年才發(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。山東安全閥門品類全</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="浙江水利閥門零售價(jià)格,閥門"

密封性能要求 </p> <p> 閥門的密封性能是指閥門各密封部位阻止介質(zhì)泄漏的能力，它是閥門**重要的技術(shù)性能指標(biāo)。閥門的密封部位有三處：啟閉件與閥座兩密封面間的接觸處；填料與閥桿和填料函的配合處；閥體與閥蓋的連接處。其中前一處的泄漏叫做內(nèi)漏，也就是通常所說的關(guān)不嚴(yán)，它將影響閥門截?cái)嘟橘|(zhì)的能力。對(duì)于截?cái)嚅y類來說，內(nèi)漏是不允許的。后兩處的泄漏叫做外漏，即介質(zhì)從閥內(nèi)泄漏到閥外。外漏會(huì)造成物料損失，污染環(huán)境，嚴(yán)重時(shí)還會(huì)造成惡事件。對(duì)于易燃易爆、或有放射的介質(zhì)，外漏更是不能允許的，因而閥門必須具有可靠的密封性能。

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。安徽氣動(dòng)閥門價(jià)格</p><p style="text-indent:25px">浙江水利閥門零售價(jià)格</p><p> 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。浙江水利閥門零售價(jià)格</p><p
