Description

磁力密封阀流体的一种前处理方法
技术领域
本发明涉及以永磁体磁场力对阀口密封的永磁截止阀、永磁单向 阀、永磁止逆地漏等磁力密封阀， 尤其是对于永磁体使阀板与岡口相 密封并与流体直接接触的磁力密封阀，为防止因 7 兹体吸附流体中的 杂质致使阀产生漏泄，使其可靠密封，对流体釆取的一种前处理的方 法。
背景技术
已有的磁力密封阀， 当流体中含有磁性杂质时，会吸附在磁力密 封阀的永磁体上， 使阀门闭合不严， 发生漏泄甚至损坏接触面， 影响 阀的正常可靠工作。如： 作为厕所自动冲洗阀和定期溢流阀的一种永 磁单向阀 （中国专利号 86104109 )、 用于提高水表或流量计准确性的 一种磁力止回阀 （如， 中国专利号 01235804. 5 )及永磁水龙头。 有 的磁力密封阀虽然已在阀口的流体入口端加过滤网，这对于 ¾ 除较大 颗粒的杂质有效， 但对于小的铁末氧化铁碎渣等， 仍会通过滤网， 而 聚集在阀口永磁铁上，从而使阀口可产生漏泄现象； 对于做为自来水 的 7j ^兹水龙头， 尤其是旧的铸铁供水系统管道， 铁磁性杂质更多， 漏 水现象会更为突出。 另外， 对于永磁密封原理的止逆地漏， 这种现象 会更为严重。
发明内容
本发明的目的是：提供磁力密封阀流体的一种前处理方法，磁力 密封阀在流体中含有的磁性杂质时，首先在阀门前部采取去除该杂质 的前处理，以避免因磁性杂质被阀口永磁体吸引集聚而产生漏泄和阀 口损坏问题。
本发明的目的是这样实现的： 对已有永磁截止阀、 7 磁单向阀、 永磁止逆地漏等阀体内以永磁体磁场力实现阀板对阀口密封的磁力 密封阀 ,尤其是其永磁体与流体直接接触的磁力密封阀，为防止漏泄， 本发明对其流体采取一种前处理方法， 其特征是： 在磁力密封阀流体 进入端阀内的前部，设置强力附加永久磁体， 以吸附流过它的流体中 的磁性杂质，并且不影响阀板的正常工作；附加永久磁体的体积大小， 应对流体正向流动时流量减小的影响不超过 50 %。 本发明优点： 由于采用上述方案， 除了可以克服阀口因磁性杂质 产生的漏泄现象外，还可以避免流体中偶有较大固体磁性杂质时，对 磁性阀口接触面的损坏。
附图说明
图 1是已有阀在密封口吸附流体中磁性杂质后状态分析图； 图 2是图 1中已有阀特殊形状的薄铁门的正视图； '
图 3是图 1中已有阀特殊形状的薄铁门的俯视图；
图 4是本发明对已有阀的改进实施例示意图。

4、 永磁环 5、 下阀体 6、 门销套
7、 导向铁 8、 薄圆铁阀板 9、 锥形体密封台
10、 磁性杂质 11、 附加永磁体 12、 固定网
13、 固定网压圈 具体实施方式 下面以本发明对以公开专利 （CN86104109A )永磁单向阀 （以下 简称 "已有阀，，） 的改进结合附图和实施例对本发明进一步说明。
参照图 1、 图 2、 图 3、 已有阀的结构， 一个由永磁环 4、 特殊形 状的薄铁阀板 3、 门销 2、 上阀体 1、 下阀体 5组成永磁单向阀。 其 中， 特殊形状的薄铁阀板 3, 由导向铁 7、 特殊形状的薄铁阀板 3的 锥形体密封台 9、 薄圆铁阀板 8、 门销套 6焊接而成。 整个阀门除薄 圆铁阀板 8、 锥形体密封台 9、 导向铁 7、 7j 兹环 4之外， 其它零件 都为非磁性材料。
首先对已有阀工作状况进行试分析： 已有阀是在永磁环 4在磁场 力作用下， 吸合特殊形状的薄铁阀板 3， 锥形体密封台 9与永磁环 4 靠接触力形成阀口来实现密封逆止功能的，但是， 在流体中一但含有 磁性杂质 （如图 1 中磁性杂盾 10 )会随着流体吸附在 ?^兹环 4上， 使其与特殊形状的薄铁阀板 3上的锥形体密封台 9及薄圆铁阔板 8(如 图 2、 图 3 )吸合不严， 而造成磁力阀口的密封作用变坏， 发生漏泄， 严重时， 甚至使阀受损； 若在永磁环 4的前部仅仅采取加过滤固定网 口， 见图 4的固定网 12的措施， 则对于磁性杂质 10, 仍会通过过滤 网而集聚在永磁环 4上， 影响阀的密封性能发生漏泄现象。
以对已有阀进行改进为实施例介绍如下： 对该已有阀，对流入磁 力阀的流体进行一种前处理， 改进实施例见示意图 4 , 磁力阀的阔口 永磁环 4 的流体进入端的前部， 即阀的进口端设置强力附加永磁体 11 , 固定在固定网 12中心， 该网被压圈 13压紧在上阀体 1上。 附加 7 兹体 11的磁力大小， 需要足以吸附几乎全部流过它的流体中的磁 性杂质 10， 使流过的流体基本不再含有磁性杂盾而影响已有阀工作 及密封性能并可以避免阀口的接触运动部件受损；永磁体的体积大小 对流体正向流动时流量的减小影响不超过 50 %。
