背景技术
在净水供应装置中,需要用到水气混合器将臭氧混合至处理好的净水中以对其进行杀菌消毒。现有的水气混合器包括三通接头、进气管路和电磁阀,三通接头的第一端为通过进气管路与臭氧发生器输出端相连通的进气端,三通接头的第二端为进水端,三通接头的第三端为出水端,电磁阀设于进气管路与臭氧发生器的输出端之间,电磁阀的控制端与控制器电连接,控制器通过电磁阀控制进气管路的通断。
现有的水气混合器用电磁阀包括阀座、线圈组件、阀芯组件和复位弹簧,其中阀座与线圈组件相连,阀座内设有过气腔,过气腔通过进气孔与外界相通,线圈组件具有与进气管路相通的进气通道。阀芯组件包括装于进气通道内的电磁杆,复位弹簧置于进气通道内且复位弹簧的一端与电磁杆的一端相接,电磁杆的另一端设有可打开或关闭所述进气孔的堵头。当控制器控制线圈组件通电时,线圈组件产生电磁力把电磁杆吸住,从而电磁杆带动堵头将过气孔打开,臭氧进入过气腔内,再通过进气通道进入进气管路。当控制器控制线圈组件断电时,电磁力消失,电磁杆在复位弹簧的作用下从线圈组件内推出,从而电磁杆带动堵头将过气孔关闭,臭氧不能进入进气管路。
现有的水气混合器用电磁阀具有以下缺点:
第一,堵头和阀座均为橡胶件,长时间受臭氧的腐蚀作用会腐蚀硬化,造成密封不严并引起返水,即水从三通接头的第二端依次通过三通接头的第一端、进气管路、电磁阀,进入臭氧发生器,从而使得臭氧发生器遇水不产生臭氧并腐蚀臭氧发生器,失去利用臭氧对水进行杀菌消毒功能,工作可靠性低。第二,由于臭氧对电磁杆有腐蚀作用,因而会产生对人体有害的物质并最终被带入水中,危害人体健康。
发明内容
本发明的目的在于,针对上述现有技术的不足,提供一种改进了的水气混合器用电磁阀及该水气混合器,密封性好,不会返水,避免出现臭氧发生器遇水不产生臭氧的情况,避免臭氧发生器被腐蚀,工 作可靠性高,不会产生有毒有害物质。
为解决上述技术问题,本发明所采用的技术方案是:
一种水气混合器用电磁阀,包括阀座、线圈组件、阀芯组件和复位弹簧,其中阀座与线圈组件相连,阀座内设有过气腔,过气腔通过进气孔与外部臭氧发生器输出端相通,线圈组件具有用于与水气混合器进气管路相通的进气通道,阀芯组件包括装于进气通道内的电磁杆,复位弹簧置于进气通道内且复位弹簧的一端与电磁杆的一端相接,电磁杆的另一端设有可打开或关闭所述进气孔的堵头,其结构特点是所述过气腔内还设有对所述进气孔封口的瓷片,所述瓷片上开设连通过气孔与过气腔的通孔,所述堵头包括与电磁杆一端固连并与通孔相对的气水闸。
借由上述结构,由于电磁阀通过瓷片与气水闸配合密封过气孔,而瓷片不会被臭氧腐蚀,因而密封性好,不会返水,避免出现臭氧发生器遇水不产生臭氧的情况,避免臭氧发生器被腐蚀,使用和维护成本低,工作可靠性高,不会产生有毒有害物质。
进一步地,所述阀芯组件还包括包覆所述电磁杆的密封套。
利用密封套将电磁阀包覆,可防止电磁杆被臭氧腐蚀而产生对人体有害的物质。
作为一种优选方式,还包括套在所述密封套顶端的连接件,所述气水闸通过螺母紧固在连接件上端;所述气水闸由陶瓷制成。
作为另一种优选方式,还包括套在所述密封套顶端的连接件,所述气水闸与连接件顶端可拆卸相连;所述气水闸由橡胶制成。
基于同一个发明构思,本发明还提供了一种水气混合器,包括三通接头和进气管路,三通接头的第一端为进气端,三通接头的第二端为进水端,三通接头的第三端为出水端,其结构特点是还包括所述的电磁阀,线圈组件通过进气管路与三通接头的第一端相连。
进一步地,还包括进气支管和进气总管,所述进气支管和进气管路的一端均与进气总管相连通,进气支管的另一端与过气腔相连通,进气管路的另一端通过进气通道与过气腔相连通;进气总管的一端密封,进气总管的另一端与三通接头的第一端相连通。
为增加气流总流量,增设进气支管和进气总管。
进一步地,所述进气支管与进气管路均与进气总管垂直,进气总管上连有水位检测器,水位检测器的输出端与控制器电连接,控制器的输出端通过电磁阀驱动电路与电磁阀的控制端电连接。
由于增设水位检测器,可以及时知道水气混合器是否返水并采取解决措施。
进一步地,所述三通接头的内设有砂头,所述砂头的进气端位于三通接头的第一端内并与过气腔相连通,砂头的出气端位于三通接头的第二端与三通接头的第三端之间。
砂头可用于将臭氧均匀混合至水中。
作为一种优选方式,所述水位检测器包括用于接地的公共电极、用于检测进气总管内水位是否超过预警水位的第一电极、用于检测外部臭氧发生器输出端与进气孔之间的臭氧输送管道内水位是否超过故障报警水位的第二电极,第一电极通过第一分压电阻与控制器的第一检测端电连接,第二电极通过第二分压电阻与控制器的第二检测端电连接,所述第一检测端和第二检测端均为可脉冲切换的I/O口和A/D检测口复用端;第一分压电阻与第一检测端之间、第二分压电阻与第二检测端之间均与电源正极电连接;还包括预警单元,所述预警单元与控制器电连接。
借由上述结构,控制器的第一检测端和第二检测端在常态下均为I/O口,控制器的第一检测端和第二检测端在脉冲检测水位时为A/D检测口。在常态下,第一检测端和第二检测端以灌电流形态输入控制器,第一电极和第二电极上电压为零伏特,不会电解水。而通过脉冲检测水位,检测时间极短,因而电解时间极短,其影响基本可以忽略。从而可以避免当水位超过预警水位时,公共电极与第一电极始终连成电解回路、持续电解,避免电解产生对人体有害的物质。
当控制器检测到臭氧输送管道内水位高于第二水位时,控制器通过电磁阀驱动电路使电磁阀关闭,臭氧无法进入三通接头,同时水也无法通过电磁阀进入臭氧发生器。。
当控制器检测到进气总管内水位高于预警水位且低于故障报警水位时,控制单元控制预警单元报警。
作为一种优选方式,所述控制器为STC12C5404AD芯片及其外围电路。
与现有技术相比,本发明密封性好,不会返水,避免出现臭氧发生器遇水不产生臭氧的情况,避免臭氧发生器被腐蚀,使用和维护成本低,工作可靠性高,不会产生有毒有害物质。
