</p><p> <span style="font-size:16px;">閥門(mén)選型的要點(diǎn)1明確閥門(mén)在設(shè)備或裝置中的用途確定閥門(mén)的工作條件：適用介質(zhì)的性質(zhì)、工作壓力、工作溫度和操縱控制方式等。正確選擇閥門(mén)的類(lèi)型閥門(mén)型式的正確選擇是以設(shè)計(jì)者對(duì)整個(gè)生產(chǎn)工藝流程、操作工況的充分掌握為先決條件的，在選擇閥門(mén)類(lèi)型時(shí)，設(shè)計(jì)人員應(yīng)首先掌握每種閥門(mén)的結(jié)構(gòu)特點(diǎn)和性能。確定閥門(mén)的端部連接在螺紋連接、法蘭連接、焊接端部連接中，前兩種常用。螺紋連接的閥門(mén)主要是公稱(chēng)通徑在50mm以下的閥門(mén)，如果通徑尺寸過(guò)大，連接部的安裝和密封十分困難。法蘭連接的閥門(mén)，其安裝和拆卸都比較方便，但是較螺紋連接的閥門(mén)笨重，價(jià)格較高，故它適用于各種通徑和壓力的管道連接。焊接連接適用于較荷刻的條件下，比法蘭連接更為可靠。但是焊接連接的閥門(mén)拆卸和重新安裝都比</span><span style="font-size:16px;">較困難，所以它的使用于通常能長(zhǎng)期可靠地運(yùn)行，或使用條件荷刻、溫度較高的場(chǎng)合。</span> 閥門(mén)的密封性能是指閥門(mén)各密封部位阻止介質(zhì)泄漏的能力，它是閥門(mén)重要的技術(shù)性能指標(biāo)。</p><div style="width:100%;text-align:
