Abstract

本实用新型公开了一种防漏止回阀,包括阀体,其特征在于:所述阀体的阀腔底部设有铰接座,所述铰接座上铰接有阀板,所述阀体的进水端具有一个斜朝上的斜面,所述阀板盖住进水端斜面,所述阀板一侧的阀体上设有支撑柱,所述支撑柱位于铰接座的正上方。本实用新型密封型好,阀板朝上开,防止阀门泄漏的防漏。

Description

防漏止回阀
技术领域
本实用新型涉及一种防漏止回阀。
背景技术
    现有技术中,止回阀的结构一般都阀板的上端铰接,下端自由转动,这样的话阀板的下端的被支撑力,阀板的下端面挡管道内有乘积的水分时,水会从阀板的间隙里流过去,影响阀门的密封性。
实用新型内容
本实用新型目的是提供一种密封型好,阀板朝上开,防止阀门泄漏的防漏止回阀。
本实用新型解决技术问题提供如下方案:
一种防漏止回阀,包括阀体,其特征在于:所述阀体的阀腔底部设有铰接座,所述铰接座上铰接有阀板,所述阀体的进水端具有一个斜朝上的斜面,所述阀板盖住进水端斜面,所述阀板一侧的阀体上设有支撑柱,所述支撑柱位于铰接座的正上方。
所述阀体的底部设有泄压孔。
本实用新型在阀腔内安装有铰接座,将阀板的下端铰接在铰接座上,这样起到了阀板的下端始终处于一个密封状态当阀腔内有少量的水时,水不会从阀板的底部留过阀门,使得阀门的密封性得到提高。
附图说明
图1为本实用新型的结构示意图。
具体实施方式
参见附图,一种防漏止回阀,包括阀体1,所述阀体1的阀腔底部设有铰接座2,所述铰接座2上铰接有阀板3,所述阀体1的进水端具有一个斜朝上的斜面4,所述阀板3盖住进水端斜面,所述阀板3一侧的阀体上设有支撑柱5,所述支撑柱5位于铰接座2的正上方。
所述阀体1的底部设有泄压孔6。
