上海龙威阀门有限公司——F745X型遥控浮球阀主导产品有闸阀、截止阀、球阀、蝶阀、止回阀、过滤器、水力控制阀、减压阀、调节阀、疏水阀、电磁阀、放料阀、针型阀、排气阀、浆液阀、安全阀、柱塞阀等。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***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。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)***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地址：真北路3508号电话：021-36150102)
