一种自清洁式过滤器
本专利技术涉及阀门领域,具体涉及用于安装在阀门上的过滤器。
技术介绍
过滤器是输送介质管道上不可缺少的一种装置,通常安装在控制阀、减压阀、泄压阀、定水位阀等。市场上有一种先导式控制阀组过滤器(如图4所示),其包括阻尼孔(a’)、阀芯(1’)、过滤片(2’)和压套(3’)。其工作原理为:液压泵出口高压油由进油口(P’)进入,先导控制油经过压套(3’)、过滤片(2’)、阀芯(1’)、阻尼孔(a’)等实现先导式控制阀组的调压控制,过滤片(2’)用保证进入阻尼孔(a’)先导油液的清洁度。液压系统中过滤的杂质残留在压套(3’)内。其存在以下缺点:因液压系统中过滤的杂质残留在压套(3’)内,无法自行排出,容易导致当过滤片(2’)堵塞,而滤片(2’)拆装有一定专业技术要求,不方便用户自行维护,需要相关专业的维修人员进行维修,产品维护成本较高。因此,如何对现有的过滤器进行改进,使其克服上述缺点是本领域技术人员亟待解决的一个问题。
技术实现思路
本专利技术的主要目的在于提供一种自清洁式过滤器,其具有自清功能,不容易造成过阻尼孔堵塞,且即使堵塞,用户只需要将过滤件拆下清洗即可,不需要专业人员维护,方便用户自行维护,产品维护成本较低,维护方便。为达到以上目的,本专利技术采用的技术方案为:一种自清洁式过滤器,包括阀芯,以及设置在阀芯上的阻尼孔,其特征在于:还包括过滤件,所述过滤件与所述阀芯采用间隙式配合,所述过滤件与所述阀芯之间形成过滤间隙,所述过滤件上还开设有通流孔,所述通流孔连通所述阻尼孔和所述过滤间隙。其通过滤件和阀芯间隙配合的方式代替现有的过滤片和压套,其 ...
