楔式閘閥的密封原理楔式閘閥的密封原理是靠楔形閘板上的兩密封面和閥體上的兩密封面楔入時(shí)的緊密結(jié)合來達(dá)密封的。使用楔形閘板的目的是為了提高輔助的密封載荷,以使金屬硬密封楔式閘閥既能對(duì)高介質(zhì)壓力,也能對(duì)低介質(zhì)壓力進(jìn)行密封。關(guān)閉時(shí)順時(shí)針旋轉(zhuǎn)閥桿，使閘閥密封面和閥體密封面密合而達(dá)到密封。金屬密封的楔式閘閥由楔入作用所產(chǎn)生的進(jìn)口端密封比壓受到介質(zhì)的作用力往往不足以達(dá)到進(jìn)口端密封.所以說金屬密封楔式閘閥屬單面強(qiáng)制密封。KROM DM160Z80-40 SN：69216952/2010

提到性價(jià)比這個(gè)詞大家都不會(huì)陌生，很多人的購物的時(shí)候都會(huì)對(duì)商品做一個(gè)比較，然后選擇性價(jià)比高的，水分測(cè)定儀行業(yè)也不例外。當(dāng)我們采購水分測(cè)定儀的時(shí)候，也會(huì)將同類商品對(duì)比，選出性價(jià)比高的。性價(jià)比是一個(gè)產(chǎn)品的性能和價(jià)格之間的比例關(guān)系，然而什么才是儀器產(chǎn)品真正的性價(jià)比呢?儀器的性能又是怎樣判定的呢?不少采購者會(huì)覺得就是儀器的功能。這樣的理解是正確的嗎?在儀器行業(yè)，許多人依舊想當(dāng)然的認(rèn)為產(chǎn)品和功能和價(jià)格之比就是性價(jià)比，咋一看來，這一說法很正確，但是深究起來卻并非如此。

如果需要的話還應(yīng)作出裝置特性曲線。在設(shè)計(jì)布置管道時(shí)，應(yīng)注意如下事項(xiàng)：合理選擇管道直徑，管道直徑大，在相同流量下、液流速度小，阻力損失小，但價(jià)格高，管道直徑小，會(huì)導(dǎo)致阻力損失急劇增大，使所選泵的壓力增加，配帶功率增加，成本和運(yùn)行費(fèi)用都增加。因此應(yīng)從技術(shù)和經(jīng)濟(jì)的角度綜合考慮。排出管及其管接頭應(yīng)考慮所能承受的大壓力。管道布置應(yīng)盡可能布置成直管，盡量減小管道中的附件和盡量縮小管道長(zhǎng)度，必須轉(zhuǎn)彎的時(shí)候，彎頭的彎曲半徑應(yīng)該是管道直徑的3～5倍，角度盡可能大于9℃。
