<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，山東專業(yè)閥門生產(chǎn)廠家，卻忽視了閥門。這樣會使整個(gè)生產(chǎn)效率降低或停產(chǎn)、或造成種種其它事件發(fā)生，山東專業(yè)閥門生產(chǎn)廠家。因此，對閥門的選用，山東專業(yè)閥門生產(chǎn)廠家、安裝、使用等都必須進(jìn)行認(rèn)真負(fù)責(zé)的工作。山東專業(yè)閥門生產(chǎn)廠家</p><div

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。外漏會造成物料損失，污染環(huán)境，嚴(yán)重時(shí)還會造成惡事件。對于易燃易爆、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。山東專業(yè)閥門生產(chǎn)廠家</p><div

</p> <p> 四、螺紋連接： </p> <p> 這是一種簡便的連接方法，常用于小閥門。又分兩種情況： </p> <p> 1、直接密封：內(nèi)外螺紋直接起密封作用。為了確保連接處不漏，往往用鉛油、線麻和聚四氟乙烯生料帶填充；其中聚四氟乙烯生料帶，使用日見廣；這種材料耐腐蝕性能很好，密封效果較好，使用和保存方便，拆卸時(shí)，可以完整地將其取下，因?yàn)樗且粚訜o粘性的薄膜，比鉛油、線麻優(yōu)越得多。 </p> <p> 2、間接密封：螺紋旋緊的力量，傳遞給兩平面間的墊圈，讓墊圈起密封作用。 </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)展起來的，它在密封效果上比一般平墊圈可靠。 </p><div
