Anti-reversal liquid filter

一种防逆形液体过滤器

Abstract

The utility model discloses an anti-reversal liquid filter which comprises a shell, wherein an upper sealing head and a lower sealing head are respectively arranged at two ends of the shell; communicating holes are formed in the upper sealing head and the lower sealing head; a water feeding pipe is connected to the lower sealing head; a filtration joint is arranged on the communicating hole in the upper sealing head; a filtration core is arranged on the filtration joint; a spraying pipe is arranged on the communicating hole in the lower sealing head; an anti-reversal ball is arranged between the spraying pipe and the water feeding pipe; a baffle is arranged at the tail end of the spraying pipe; and a plurality of spraying holes are formed in the side wall of the spraying pipe. The anti-reversal liquid filter is simple in structure, low in cost and convenient to use and can be used for filtering solid substances from liquid; by using a manner of arranging the anti-reversal ball between the water feeding pipe and the spraying pipe, when an external pump does not work or is blocked, water cannot enter the external pump; in order to prevent impurities from falling into the water feeding pipe, the additionally arranged anti-reversal ball can stop the impurities; and the water feeding pipe can be prevented from being blocked.
本实用新型公开了一种防逆形液体过滤器,包括壳体,在壳体的两端分别安装有上封头和下封头,上封头和下封头上均设置有连通孔,在下封头上连接有进水管,在上封头的连通孔上安装有过滤接头,在过滤接头上安装有滤芯,在下封头的连通孔上安装有喷射管,在喷射管与进水管之间安装有防逆球,在喷射管上的末端安装有挡板,在喷射管的侧壁上设置有多个喷射孔。本实用新型不仅结构简单,而且成本低廉、使用方便,还能滤除液体中的固体物质,通过在进水管与喷射管之间安装防逆球的方式,当外界泵没有工作或者是堵塞的时候,水不能进入,为了防止杂质下降落入进水管,增加的防逆球可以完成杂质的阻挡,避免对进水管造成堵塞。
