Abstract

一种嵌入式安装防真空止回流阀，包括阀体、单向阀、上滤芯和下滤芯，所述阀体呈中空结构，所述阀体内腔上部安装上滤芯，所述阀体内腔中部安装所述单向阀，所述阀体内腔下部安装所述下滤芯。本实用新型提供了一种更换方便、有效防止回流的嵌入式安装防真空止回流阀。

Description

嵌入式安装防真空止回流阀
技术领域
本实用新型涉及一种油箱的阀门。
背景技术
现有的油箱阀门，通常是油箱自带外接的结构，安装不牢固，不耐振，密封效果差，更换不方便，止回流效果不好的功能。
发明内容
为了克服已有油箱阀门的更换不方便、不能防止回流的不足,本实用新型提供了一种更换方便、有效防止回流的嵌入式安装防真空止回流阀。
本实用新型解决其技术问题所采用的技术方案是：
一种嵌入式安装防真空止回流阀，包括阀体、单向阀、上滤芯和下滤芯，所述阀体呈中空结构，所述阀体内腔上部安装上滤芯，所述阀体内腔中部安装所述单向阀，所述阀体内腔下部安装所述下滤芯。
进一步，所述防真空止回流阀还包括密封圈，所述密封圈套装在所述阀体外壁。所述密封圈优选为O形圈。
本实用新型的有益效果主要表现在：更换方便、有效防止回流。
附图说明
图1是嵌入式安装防真空止回流阀的分解图。
图2是嵌入式安装防真空止回流阀的剖视图。
具体实施方式
下面结合附图对本实用新型作进一步描述。
参照图1和图2，一种嵌入式安装防真空止回流阀，包括阀体3、单向阀2、上滤芯1和下滤芯5，所述阀体3呈中空结构，所述阀体3内腔上部安装上滤芯1，所述阀体3内腔中部安装所述单向阀2，所述阀体3内腔下部安装所述下滤芯5。
进一步，所述防真空止回流阀还包括密封圈4，所述密封圈4套装在所述阀体3外壁。所述密封圈优选为O形圈。
本实施例的阀体嵌入在油箱上的结构，缩小机器的外形尺寸，装配快捷方便，密封座上过滤滤芯上下端各安装一个，中间安装单向阀，密封圈装配在密封座的外围；该结构防止机器在工作中油箱被抽成真空，在保证通气的前提下过滤进入油箱内的空气，使空气清洁，无颗粒状杂物；同时保证燃油在正常情况下不回流，使油箱内的燃油不外漏；通用性强；结构简单；方便控制品质一致性。
