F745X型遥控浮球阀
价格:88.00
F745X型遥控浮球阀结构特点F745X型遥控浮球阀由主阀和浮球阀及接管系统组成,主阀阀体采用全通道、直流式、流线型设计,并采取膜片式或活塞式两类结构。接管系统由浮球阀、球阀和接管组成。本产品直接利用浮球导阀进行液面控制,不需要其它装置和能源,结构简单,维护保养简便,控制不受水压影响,液面控制准确度高,密封可靠。工作原理当管道从进水端给水时,由于球阀、浮球阀是常开的,水通过微型过滤器、球阀B、控制室、球阀A、浮球阀进入水池,主阀控制室不形成压力,主阀开启,水塔(池)供水。当水塔(池)的水面上升至设定高度时,浮球浮起关闭浮球阀,控制室水压升高推动主阀关闭,供水停止。当水池水面下降后,浮球阀重新开启,控制室水压下降,主阀再次开启继续供水,保持液面的设定高度。工作特点1、关闭严密可靠。主阀密封采用橡胶密封环密封,关闭动力由主阀控制室自动形成,保持合适关闭力,密封寿命和可靠性高。2、操作方便,无需为阀门另配电控系统。阀门随液面高度变化自动开启和关闭。3、阀体采用了全通道、直流式、流线型设计。水力损失小,节能效果好。功能与用途本阀门安装在水塔、水池的进口端管路上,完成保持水塔、水池液面的规定高度的功能。本系列阀门产品广泛用于高层建筑、生活区等供水管网系统的水塔、水池等设施的液面高度自动控制。主要技术参数公称压(Mpa)壳体试验压力(MPa)密封试验压力(MPa)调压范围(MPa)最低动作压力(MPa)适用介质介质温度(℃)1.01.51.10.09-0.8≥0.07水0-801.62.41.760.15-1.42.53.752.750.2-2.0主要零件材料零件名称零件材料阀体阀盖WCB阀座阀盘铜合金/2Cr13密封圈O型圈丁腈橡胶阀杆2Cr13弹簧50CrVA缸套活塞(活塞型)2Cr13膜片(膜片型)夹织物丁腈橡胶调节阀球阀铜合金过滤器不锈钢部件列表:1、浮球2、流量调节阀3、过滤器连接尺寸DNLHDmmD1mmbmmD2mmn-ΦdmmmmPN1.0PN1.6PN2.5PN1.0PN1.6PN2.5PN1.0PN1.6PN2.5PN1.0PN1.6PN2.5PN1.0PN1.6PN2.5402402701501501501101101101818188888844-17.54-17.54-1850240270165165165125125125202020102102994-17.54-17.54-18652703401851851851451451452020221221221184-17.54-17.58-18803004002002002001601601602222241331331328-17.58-17.58-181003504402202202351801801902424241581581568-17.58-17.58-221254004602502502702102102202626261841841848-17.58-17.58-261504805002852853002402402502626282122122118-228-228-262005006403403403602952953102830302682682748-2212-2212-2625060569039540542535035537028323232032033012-2212-2612-3030070082044546048540041043028323437037038912-2212-2616-3035080095050552055546047049030363843043044816-2216-2616-33400900140056558062051552555032384048248250316-2616-3016-364501000158061564067056558560032404253255054820-2620-3020-365001100160067071573062065066034424458558560920-2620-3320-366001300181578084084572577077036484668568572020-3020-3620-397001400204089591096084084084540545080080082024-3024-3624-428001500235010151025108595095099044585490590592524-3324-3924-489001700260611151125118510501050109046625810051005102828-3328-3928-4810001900276512301255132011601170121050666211101110114028-3628-4228-5612002050295014551485153013801390142056527013301328135032-3932-4832-5514002200318016751685175515901590164062587615301530156036-4236-4836-6016002400340019151930195518201820186068648417501750178040-4840-5540-60安装示意图)
