不銹鋼閘閥 304材質(zhì)不銹鋼法蘭閘閥 Z41W-16P DN80的啟閉件是閘板，閘板的運(yùn)動(dòng)方向與流體方向相垂直，閘閥只能作全開(kāi)和全關(guān)，不適合作調(diào)節(jié)和節(jié)流。閘板有兩個(gè)密封面，zui常用的楔式閘板閥的兩個(gè)密封面形成楔形，楔形角隨閥門(mén)參數(shù)而異，通常為5o。楔式閘閥的閘板可以做成一個(gè)整體，叫做剛性閘板；也可以做成能產(chǎn)生微量變形的閘板，以改善其工藝性，彌補(bǔ)密封面角度在加工過(guò)程中產(chǎn)生的偏差，這種閘板叫做彈性閘板。 閘閥關(guān)閉時(shí)，密封面可以只依靠介質(zhì)壓力來(lái)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(lái)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(mén)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。 不銹鋼閘閥 304材質(zhì)不銹鋼法蘭閘閥 Z41W-16P DN80具有以下優(yōu)點(diǎn)； 1．流體阻力小，密封面受介質(zhì)的沖刷和侵蝕小。 2．開(kāi)閉較省力。 3．介質(zhì)流向不受限制，不擾流、不降低壓力。 4．形體簡(jiǎn)單，結(jié)構(gòu)長(zhǎng)度短，制造工藝性好，適用范圍廣。 公稱(chēng)壓力或壓力級(jí)：PN1.0-16.0MPa、ANSI CLASS 150-300LB、JIS10-20K 公稱(chēng)通徑或口徑：DN10～1000、NPS 1/2 ～36" 連接方式：法蘭、對(duì)焊、螺紋等適用溫度：-196℃～700℃ 驅(qū)動(dòng)方式：手動(dòng)、傘齒輪傳動(dòng)、氣動(dòng)、電動(dòng)、液動(dòng)、氣液聯(lián)動(dòng)、電液聯(lián)動(dòng) 閥體材料：WCB、ZG1Cr18Ni9Ti、ZG1Cr18Ni12Mo2Ti、CF8(304)、CF3(304L)、CF8M(316)、CF3M(316L)、Ti。選用不同的材質(zhì)，可分別適用于水、蒸汽、油品、硝酸、醋酸、氧化性介質(zhì)、尿素等多種介質(zhì)。 Z41W-16P DN80:Z41H-10C DN32/Z41H-10C DN40/Z41H-10C DN50/Z41H-10C DN65/ Z41H-10C DN80/Z41H-10C DN100/Z41H-10C DN125/Z41H-10C DN150/Z41H-10C DN200/ Z41H-10C DN250/Z41H-10C DN300/Z41H-10C DN350/Z41H-10C DN400/Z41H-10C DN450/ Z41H-10C DN500/Z41H-10C DN600/Z41H-10C DN700/Z41H-10C DN800/Z41H-10C DN900/ Z41H-10C DN1000/Z41H-16C DN32/Z41H-16C DN40/Z41H-16C DN50/Z41H-16C DN65/ Z41H-16C DN80/Z41H-16C DN100/Z41H-16C DN125/Z41H-16C DN150/Z41H-16C DN200/ Z41H-16C DN250/Z41H-16C DN300/Z41H-16C DN350/Z41H-16C DN400/Z41H-16C DN450/ Z41H-16C DN500/Z41H-16C DN600/Z41H-16C DN700/Z41H-16C DN800/Z41H-16C DN900/ Z941H-16C DN1000/Z41H-25C DN32/Z41H-25C DN40/Z41H-25C DN50/Z41H-25C DN65/ Z41H-25C DN80/Z941H-25C DN100/Z41H-25C DN125/Z41H-25C DN150/Z41H-25C DN200/ Z41H-25C DN250/Z41H-25C DN300/Z41H-25C DN350/Z41H-25C DN400/Z41H-25C DN450/ Z41H-25C DN500/Z41H-25C DN600/Z41H-25C DN700/Z41H-25C DN800/Z41H-25C DN900/ Z41H-25C DN1000/Z41H-40C DN32/Z41H-40C DN40/Z41H-40C DN50/Z41H-40C DN65/ Z41H-40C DN80/Z41H-40C DN100/Z41H-40C DN125/Z41H-40C DN150/Z41H-40C DN200/ Z41H-40C DN250/Z41H-40C DN300/Z41H-40C DN350/Z41H-40C DN400/Z41H-40C DN450/ Z41H-40C DN500/Z41H-40C DN600/Z41H-40C DN700/Z41H-40C DN800/Z41H-40C DN900/ Z41H-40C DN1000/Z41H-64C DN32/Z41H-64C DN40/Z41H-64C DN50/Z41H-64C DN65/ Z41H-64C DN80/Z41H-64C DN100/Z941H-64C DN125/Z41H-64C DN150/Z41H-64C DN200/ Z41H-64C DN250/Z41H-64C DN300/Z41H-64C DN350/Z41H-64C DN400/Z41H-64C DN450/ Z41H-64C DN500/Z41H-64C DN600/Z41H-64C DN700/Z41H-64C DN800/Z41H-64C DN900/ Z41H-64C DN1000/Z41H-100C DN32/Z41H-100C DN40/Z41H-100C DN50/Z41H-100C DN65/ Z41H-100C DN80/Z41H-100C DN100/Z41H-100C DN125/Z41H-100C DN150/Z41H-100C DN200/Z41H-100C DN250/Z41H-100C DN300/Z41H-100C DN350/Z41H-100C DN400/ Z41H-100C DN450/Z941H-100C DN500/Z41H-100C DN600/Z41H-100C DN700/Z41H-100C DN800/Z41H-100C DN900/Z41H-100C DN1000
