閥門密封圈材料使用條件非金屬類:1聚四氟乙烯,代號F聚四氟乙烯多用于溫度t≤232℃、公稱壓力PN≤、閘閥、球閥等。2合成橡膠,代號X合成橡膠的耐油、耐溫、耐腐蝕等綜合性能優(yōu)于天然橡膠。一般合成橡膠的使用溫度t≤150℃，天然橡膠t≤60℃，橡膠用于公稱壓力PN≤1MPa的截止閥、閘閥、隔膜閥、蝶閥、止回閥、夾管閥等閥門的密封。3尼龍,代號N尼龍具有摩擦系數(shù)小、耐腐蝕性好等特點(diǎn)。尼龍多用于溫度t≤90℃、公稱壓力PN≤32MPa的球閥、截止閥等。金屬類:4巴氏合金,代號B巴氏合金用于溫度t-70~150℃、公稱壓力PN≤。5鉻不銹鋼,代號H鉻不銹鋼常用牌號有2Cr13、3Cr13經(jīng)調(diào)質(zhì)處理，耐腐蝕性能好。常用于溫度t≤450℃、公稱壓力PN≤32MPa的水、蒸汽和石油等介質(zhì)的閥門上。6鉻鎳鈦不銹鋼,代號R鉻鎳鈦不銹鋼常用牌號為1Cr18Ni9ti，其耐腐性、耐沖蝕性和耐熱性能較好。適用于溫度t≤600℃、公稱壓力PN≤、硝酸等介質(zhì)中，用于截止閥、球閥等。7銅合金。</p><div

確定閥門的工作條件：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。 </p> <p> <br /> </p> <p> 2、正確選擇閥門的類型 </p> <p> <br /> </p> <p> 閥門型式的正確選擇是以設(shè)計(jì)者對整個(gè)生產(chǎn)工藝流程、操作工況的充分掌握為先決條件的，在選擇閥門類型時(shí)，設(shè)計(jì)人員應(yīng)首先掌握每種閥門的結(jié)構(gòu)特點(diǎn)和性能。 </p> <p> <br /> </p> <p> 3、確定閥門的端部連接 </p> <p> <br /> </p> <p> 在螺紋連接、法蘭連接、焊接端部連接中，前兩種**常用。螺紋連接的閥門主要是公稱通徑在50mm以下的閥門，如果通徑尺寸過大，連接部的安裝和密封十分困難。 </p> <p> <br /> </p> <p> 法蘭連接的閥門，其安裝和拆卸都比較方便，但是較螺紋連接的閥門笨重，價(jià)格較高，故它適用于各種通徑和壓力的管道連接。 </p> <p> <br /> </p> <p> 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拆卸和重新安裝都比較困難，所以它的使用于通常能長期可靠地運(yùn)行，或使用條件荷刻、溫度較高的場合。 </p> <p> <br /> </p> <p> 4、閥門材質(zhì)的選擇 </p> <p> <br /> </p> <p> 選擇閥門的殼體、內(nèi)件和密封面的材質(zhì)，除了考慮工作介質(zhì)的物理性能（溫度、壓力）和化學(xué)性能（腐蝕性）外，還應(yīng)掌握介質(zhì)的清潔程度（有無固體顆粒），除此之外，還要參照國家和使用部門的有關(guān)規(guī)定。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> <br />
