手动对夹橡胶蝶阀上海良工阀门厂有限公司蝶阀又叫翻板阀，是一种结构简单的调节阀，同时也可用于低压管道介质的开关控制。蝶阀是指关闭件（阀瓣或蝶板）为圆盘，围绕阀轴旋转来达到开启与关闭的一种阀，在管道上主要起切断和节流作用。蝶阀启闭件是一个圆盘形的蝶板，在阀体内绕其自身的轴线旋转，从而达到启闭或调节的目的。蝶阀适用于发生炉、煤气、***、液化***、城市煤气、冷热空气、化工冶炼和发电环保等工程系统中输送各种腐蚀性、非腐蚀性流体介质的管道上，用于调节和截断介质的流动。蝶阀分类有：手柄蝶阀、涡轮蝶阀、气动蝶阀、电动蝶阀等。PN10级中线对夹蝶阀法兰尺寸及安装尺寸表(见图1)公称通径DN(mm)尺寸(am)d0DD1D2D3*D4H*fN-dB*D5D6D7BS*K*SoT50571651251025950434-Φ17.522327638942443.51.565731851451227565434-Φ17.524468910844.75541.580892001601339180438-Φ17.52464103912045.255420100108220180158110100438-Φ17.5268613515052.15541.0125133250210184135125438-Φ17.528111159181545541.75150159285240212161150438-Φ2228135188420855.8654.51.25200219340295268221208538-Φ2230192238226060.66761.152502733953503202752556312-Φ2232242292432065.36982.353003254454003703273086412-Φ223229234437576.96981.53503775054604303793407416-Φ223432237540576.571091.254004265655154824294057416-Φ263838043847086.571091.754504786155655324814558420-Φ2642428489521105.671091.75005296706205855325058420-Φ2642428489521105.671091.66006307807256856336058520-Φ305052765469315271092.07007208958408007237059524-Φ3052675744800163811103.O80082010159509058238109524-Φ3354770850906188811103.5注：“*”尺寸为参考尺寸，也可以由选阀设计人员自定。PN16级中线对夹蝶阀法兰尺寸及安装尺寸表(见图1)公称通径DN(mm)尺寸(am)d0DD1D2D3*D4H*fn-dB*D5D6D7BS*K*S0T50571651251025950434-Φ17.5223276.38942443.51.565731851451227565434-Φ17.524468910844.75541.580892001601339180438-Φ17.52464103.912045.255420100108220180158110100438-Φ17.5268613515052.15541.0125133250210184135125438-Φ17.528111159181545541.75150159285240212161150438-Φ2228135188.420855.8654.51.25200219340295268221208538-Φ2230192238.226060.66761.152502734053553202752556312-Φ2632242292.432065.36982.353003254604103703273086412-Φ263229234437576.96981.53503775204704303793407416-Φ263432237540576.571091.254004265805254824294057416-Φ303838043847086.571091.754504786405855324814558420-Φ3042428489521105.671091.75005297156505855325058420-Φ3342428489521105.671091.66006308407706856336058520-Φ365052765469315271092.0注：“*”尺寸为参考尺寸，也可以由选阀设计人员自定。技术快讯：本发明提出的一种用于阀门外观检测的装置，包括转动盘、外观检测探头、进料通道、出料通道、次品通道、风机、送料机构和控制模块组成，转动盘由内盘和外盘组成，内盘保持静止，外盘的内周围绕内盘的外周以内盘为轴沿着一个方向转动，外盘上周向平均分布有多个安置槽，安置槽的结构与待检测阀门的外观相配合，进料通道、次品通道和出料通道顺着外盘转动的方向顺序的传动连接在外盘上，进料通道、次品通道和出料通道相对内盘保持静止，外观检测探头和风机安装在内盘上，风机的出风口朝向次品通道，控制模块同时连接外观检测探头和风机。本发明提出的一种用于阀门外观检测的装置，结构简单，制造成本低，占地面积少，且效率高，效果好。规格1.0MPa1.6MPa双头螺柱(适用“A”型蝶阀)六角螺柱(适用“LT”型蝶阀)双头螺柱(适用“A”型蝶阀)六角螺柱(适用“LT”型蝶阀)mminch数量直径×L1总长L数量直径×L1数量直径×L1总长L数量直径×L15024M16×1101304×2M16×404M16×1101304×2M16×40652.54M16×1201404×2M16×454M16×1201404×2M16×458038M16×1201408×2M16×458M16×1201408×2M16×4510048M16×1301508×2M16×508M16×1301508×2M16×5012558M16×1301508×2M16×508M16×1301508×2M16×5015068M20×1401658×2M20×508M20×1401658×2M20×5020088M20×1501758×2M20×5512M20×15017512×2M20×552501012M20×16018512×2M20×6012M24×16018512×2M24×603001212M20×17019512×2M20×6512M24×17020012×2M24×653501416M20×17019516×2M20×6516M24×17020016×2M24×654001616M24×19022016×2M24×7516M27×20023016×2M27×754501820M24×22025020×2M24×8020M27×22025420×2M27×805002020M24×26029020×2M24×9020M30×26029420×2M30×906002420M27×29032420×2M27×10020M33×29033420×2M33×1007002824M27×300334--20M33×3003414×2M33×908003224M30×300364--24M36×330375)
