Abstract

一种控制流体通断的装置，主要由开关把手、内管、外管、入流口、上部密封圈、下部密封圈、底座、内管锥口、内管密封面、内管导向片、出流口等构成，关闭时按下开关把手，内管密封面插入下部密封圈中，使装置处于断流关闭状态，开启时上拉开关把手，内管密封面与下部密封圈脱离，流体由出流口流出。

Description

一种控制流体通断的装置
所属技术领域
本发明涉及管道系统中接通或截断管路中流体的阀门装置。 
背景技术
公知的控制流体通断的阀门，在结构上主要有截门形、闸门形、蝶形、旋塞和球形，如截止阀、闸阀、蝶阀、旋塞阀、球阀等。 
现有的阀门均采取阀门直接封堵入流口的方式，造成封堵压力增大或过流面积减小，如：截门阀和闸门形阀的驱动力矩大，必须用螺杆控制阀门开启关闭，开启关闭时间长；截门形阀和蝶形阀的过流面积缩小，流体动能损失大；球阀加工精度高，造价昂贵，如管道内有杂质，容易被杂质堵塞，导致阀门无法打开。 
发明内容
为了克服公知阀门的不足，本发明提供一种操作控制力矩小，流体动能损失小，适合各种流体通断控制的装置。 
本发明所采用的技术方案是：该装置由开关把手、内管、外管、入流口、下部密封圈、底座、内管锥口、内管密封面、内管导向片、上部密封圈、出流口等组成，内管可在外管中水平旋转和上下移动，内管既是流道又是阀门，断流时内管不直接封堵入流口，利用内管密封面和底座上的下部密封圈实现对流体的通断控制，按下开关把手，内管下移，在内管导向片的引导下，内管锥形口对准下部密封圈的内径，内管锥形口端部的外径小于下部密封圈的内径，继续按压开关把手，内管锥形口插到底座时，内管密封面插入下部密封圈中，形成密封，使装置处于断流关闭状态，和内管连通的出流口与外部大气相通，内管受管道内部压力影响甚微，下压关闭时用力很小，上拉开关把手，内管上移，内管密封面与下部密封圈脱离，流体经入流口流入内管，由出流口流出，底座为可拆卸的壳体，可以容纳流体中的沉淀物。 
本发明的有益效果是；利用内管密封面和底座上的下部密封圈实现对流体的通断控制，内管既是流道又是阀门，断流时内管不直接封堵入流口，通断控制力矩小，结构简单，外管和内管的直径差小，流体的动能损失小。 
附图说明
下面结合附图1和实施例对本发明进一步说明，图1是本发明原理图。 
图1中：1.开关把手，2.内管，3.入流口，4.下部密封圈，5.底座，6.内管锥口，7.内管密封面，8.内管导向片，9.外管，10.上部密封圈，11.出流口。 
具体实施方式
在图1中，关闭过程：向下按压开关把手(1)，内管(2)沿着外管(9)的内壁向下运动，在内管导向片(8)的引导下，内管锥形口(6)对准下部密封圈(4)的内径，当内管锥形口(6)插到底座(5)时，内管密封面(7)插入下部密封圈(4)中，流体无法由入流口(3)流入内管(2)中，流体被断开，装置形成关闭状态，上部密封圈(10)处于内管(2)和外管(9)之间，避免流体由内管(2)和外管(9)之间渗出。 
开启过程：向上提拔开关把手(1)，内管(2)向上运动，内管密封面(7)与下部密封圈(4)脱离，流体由入流口(3)进入内管(2)，经出流口(11)流出。 
若底座(5)中沉积物较多时，随时拆卸清洗。 

Claims (4)

1.一种控制流体通断的装置，主要由开关把手、内管、外管、入流口、上部密封圈、下部密封圈、底座、内管锥口、内管密封面、内管导向片、出流口等构成，其特征是：利用内管密封面和底座上的下部密封圈实现对流体的通断控制。 
2.根据权利要求1所述的一种控制流体通断的装置，其特征是：内管既是流道又是阀门，断流时内管不直接封堵入流口。 
3.根据权利要求1所述的一种控制流体通断的装置，其特征是：在内管导向片的引导下，内管锥形口对准下部密封圈的内径。 
4.根据权利要求1所述的一种控制流体通断的装置，其特征是：内管锥形口端部的外径小于下部密封圈的内径。
