太阳能热水器的电磁阀怎样安装?
电磁阀两头都是活节,更换时先关闭自来水和太阳能热水器的热水管道,直接拔下电磁阀上盖,松开连接电线,然后用活动板手拧下即可,安装时注意电磁阀方向,拿不准的可以在拆下旧阀前先拍照,安装新阀时参考旧阀方向,另外,电磁阀内有个塑料滤网,安装时别掉出来。
什么是热水器电磁阀?
一个热水器就一个电磁阀.它起的开气或闭气的作用.通常电磁阀损坏的就两种现象,一种是能听见打火的声音,而不燃火.另一种是,能瞬间燃一下火就熄灭.
我们来说说:能听见打火的声音,而不燃火吧, 那是点火器和风力开关都正常工作的情况下,电磁阀自身线圈损坏造成的没有电磁吸力,所以不能导通气体导致不能燃火
能瞬间燃一下火就熄灭. 这种情况还有风力开关损坏和热感温针都会出现这样的情况.
电磁阀由于燃气杂质和线圈老化,导致电磁能力下降,在点火器驱动电磁阀瞬间,它能吸和,但由于吸力不够被电磁阀的弹簧弹出 造成能瞬间燃一下火就熄灭
风力开关损坏就相当于风机没有运转,控制电路会进行保护,出现的现象就是,打火时,能瞬间燃一下火就熄灭
热感温针不能感温,导致点火器误以为没有燃火,从而进行保护.出现的现象就是,火随打火声完而熄灭
万家乐燃气热水器电磁阀在哪
万家乐燃气热水器电磁阀在连接燃气管接口向上5厘米处,热水器的左下方。电磁阀本身结构简单,价格也低,比起调节阀等其它种类执行器易于安装维护,更显著的是所组成的自控系统简单得多,价格要低得多,由于电磁阀是开关信号控制,与工控计算机连接十分方便,在当今电脑普及,价格大幅下降的时代,电磁阀的优势就更加明显。
电磁阀工作原理
冷水进入热水器,流经水气联动阀体在流动水的一定压力差值作用下,推动水气联动阀门,并推动微动开关将电源接通并启动脉冲控制器,打开燃气通气电磁阀门,将燃气热水器燃烧器点燃;燃烧器点燃后,火焰检测元件通过检测火焰给出火焰信号予脉冲控制器。
通过维持电流将电磁阀打开,维持燃烧器的正常燃烧,如果当点火失败,脉冲点火器因无检测到火焰的维持电流信号,无法维持电磁阀的正常开启,关闭电磁阀,切断燃气的供应。
燃气热水器的电磁阀都是通用的吗?
不是都通用,各个品牌有些是通用,有些不能通用,主要看安装尺寸,电压一样就可以通用。
热水器电磁阀故障怎么处理?一般会有哪些原因?
热水器电磁阀是精密的电器元件,一般是不容易坏的,往往是电路、机械控制系统出问题,不能提供正常的控制电压造成的,建议请专业人员帮助检测,查询故障,不同型号采用不同的电路、和不同型号的电磁阀,有的与气体、和机械结构联动,下图是一种电磁阀的内部结构图:
