Abstract

本发明涉及一种无阻足阀，包括阀体、阀盖和阀口，阀盖上开孔，并通过皮碗紧固封闭该孔，皮碗内设一杠杆，杠杆一端与皮碗内表面底端接触，杠杆另一端与阀板连接，该阀板置于阀口下侧并可完全封住阀口，且阀板与杠杆连接端下侧垂直于阀体固定一转轴，所述阀板可绕转轴转动。本发明通过转轴杠起阀板，使阀板全部打开，消除流体阻力。

Description

一种无阻足阀
技术领域
本发明涉及一种足阀。
背景技术
传统的足阀是靠泵吸液时，通过流体将阀板顶开，由此造成流体阻力很大，白白浪费资源。
发明内容
本发明的目的在于，针对现有技术的不足，提供一种无阻足阀，可消除流体阻力，提高经济效益。
本发明的技术方案为，一种无阻足阀，包括阀体、阀盖和阀口，其特征是，阀盖上开孔，并通过皮碗紧固封闭该孔，皮碗内设一杠杆，杠杆一端与皮碗内表面底端接触，杠杆另一端与阀板连接，该阀板置于阀口下侧并可完全封住阀口，且阀板与杠杆连接端下侧垂直于阀体固定一转轴，所述阀板可绕转轴转动。
当启动泵后，阀体内便形成负压，皮碗在大气压力下向内压入，紧紧的将杠杆向下压住，通过转轴杠起阀板，迫使阀板全部打开，这样阀体内流体不至受到阀板的阻挡，从而消除了流体阻力。
停泵后，阀体内立即又变成正压，在极短的时间内，皮碗在正压的作用下又向外凸起，解除施加在杠杆上的压力，这时阀板靠自重下落，并在回流液的作用下，关闭阀口。
由以上可知，本发明通过转轴杠起阀板，使阀板全部打开，消除流体阻力。
附图说明
图1为本发明无阻足阀的结构示意图；
图2为本发明无阻足阀的安装示意图。
具体实施方式
如图1所示，一种无阻足阀，包括阀体1、阀盖2和阀口8，阀盖2上开孔3，并通过皮碗4紧固封闭该孔3，皮碗4内设一杠杆6，杠杆6一端与皮碗4内表面底端接触，杠杆6另一端与阀板5连接，该阀板5置于阀口12下侧并可完全封住阀口8，且阀板5与杠杆6连接端下侧垂直于阀体1固定一转轴7，所述阀板5可绕转轴7转动。
如图2所示，启动泵10，打开泵阀9，液池12内的流体经吸液管11被抽吸，再通过无阻足阀13进行泵液过程。
