2、起到負(fù)載阻力的作用：節(jié)流閥還能起到一定程度上的負(fù)載作用，這只是節(jié)流閥具有的一部分功能，節(jié)流閥的主要作用仍然是節(jié)流調(diào)速。 3、壓力緩沖的作用：節(jié)流閥能對流體起到壓力緩沖的作用，當(dāng)流體經(jīng)過節(jié)流閥流入時(shí)，節(jié)流閥可以在一定程度上阻礙流體的運(yùn)行從而減少?zèng)_擊力。</p><p

③止回閥：防止介質(zhì)倒流。如止回閥。 ④分配閥：改變介質(zhì)的流向，起分配作用。如三通旋塞、三通截止閥等。 ⑤安全閥：壓力超限定數(shù)值時(shí)，排放多余的介質(zhì)，保證設(shè)備安全。如安全閥、事故閥； ⑥阻氣排水閥：留存氣體、排除凝結(jié)水，如疏水閥。 ⑦開斷閥：切斷或接通管路介質(zhì)。如截至閥、閘閥、球閥、旋塞閥等；

style="text-indent:25px">閘閥是指閘板關(guān)閉件沿通路中心線的垂直方向移動(dòng)的閥門。一般由閥體、閥座、閥桿、閘板、閥蓋、密封圈幾部分組成，可通過對傳動(dòng)裝置和閘閥的配備可轉(zhuǎn)化出多樣化的電動(dòng)閘閥與氣動(dòng)閘閥，閘閥的閘板隨閥桿一起作直線運(yùn)動(dòng)的，通常在升降桿上有梯形螺紋，通過閥門頂端的螺母以及閥體上的導(dǎo)槽，將旋轉(zhuǎn)運(yùn)動(dòng)變?yōu)橹本€運(yùn)動(dòng)，也就是將操作轉(zhuǎn)矩變?yōu)椴僮魍屏Α?閘閥開啟時(shí)：閘板提升高度等于閥門通徑的1：1倍，流體的通道完全暢通。閘閥關(guān)閉時(shí)密封面可以只依靠介質(zhì)壓力來密封，即依靠介質(zhì)壓力將閘板的密封面壓向另一側(cè)的閥座來保證密封面的密封，這就是自密封。大部分閘閥是采用強(qiáng)制密封的，即閥門關(guān)閉時(shí)，要依靠外力強(qiáng)行將閘板壓向閥座 , 以保證密封面的密封性。在管路中閘閥只能作全開和全關(guān)切斷用，不能作調(diào)節(jié)和節(jié)流。閥門的工作原理是什么？費(fèi)斯托換向閥</p><p style="text-indent:25px">閥門的優(yōu)點(diǎn)有哪些？我們該怎么挑選？費(fèi)斯托換向閥</p><p style="text-indent:25px">蝶閥的種類很多,根據(jù)其結(jié)構(gòu)特點(diǎn)和用途,一般可以分為以下兩大類： 1.密封型蝶閥這種蝶閥在關(guān)閉時(shí)能夠保證完全密封,在管道上可以作為切斷用,密封圈通常采用橡膠或塑料制成。但是,目前國內(nèi)也有采用金屬材料制成的密封圈,稱為雙偏心或三偏心蝶閥,也能保證良好的密封性能。 2.非密封型蝶閥這種蝶閥在關(guān)閉狀態(tài)時(shí)不能保證完全密封,在管道上只能作為節(jié)流用。其密封副材料通常采用的是金屬。作為流量控制用的蝶閥,大多采用金屬密封副。蝶閥和管道連接的方式有對夾式、雙法蘭式和單法蘭式三種,但較為常用的是對夾式和雙法蘭式。對夾式是用雙頭螺栓將閥門連接在管道上的兩法蘭之間。閥體形式可以為單法蘭式、無法蘭式或U形截面式。費(fèi)斯托換向閥</p><p
