BFDG7M41HR-10P,BFDG7M42HR-10C,BFDG7M43HR-10P,BFDG7M41HR-16C,管力阀
一、BFDG7M41HR管力阀概述:
该阀是我公司工程技术人员参照国内外同类型的先进产品进行设计。吸收微阻缓闭止回阀、液控止回蝶阀、多功能水利控制阀的基础上研制而成,是水泵控制阀的换代新产品。它兼具电动闸、电动蝶阀以及止回阀的功能,并通过快关和缓闭的动作来消除水锤危害,保护水泵及管网系统安全。该阀是当前国内外结构最新颖、性能最先进、进行最可靠的泵站新型控制设备,主要用于自动化给排水泵站的离心泵、冶金、石化、水利、市政、环保等行业供排水系统。
二、BFDG7M41HR管力阀工作原理:
1.开阀
当水泵启动后进口端水经过、过滤器、闸阀、高压管、进入活塞缸下部,在水的压力下推动活塞上下带动小阀板缓慢开启,大阀板在水力的推动下与小阀板同时开启,完成开阀。
2.关阀
停泵时阀内流速急剧降低,大阀板在重力的作用下快速关闭,截断90%的水流,出口端的回水压力水进入过滤器、闸阀、高压管、进入活塞缸上部,在水的压力下推动活塞带动小阀板缓慢关闭,最终实现关闭。
三:BFDG7M41HR管力阀主要特点:管力阀结构;本阀门由阀体,橡胶管套、大小阀杆闸板、上下导柱等零件组成。
2)管力阀工作原理:管力阀在泥沙和杂物较多的一些情况下(如黄河水质,污水处理系统等),阀门控制管路容易被堵塞,导致阀门失灵;大的杂物还容易把阀板卡住,导致阀门密封不严;还有一些特殊情况,阀门开关时水锤很大,导致阀门开关时响声巨大,甚至造成事故。
