一种可调式柔性截流装置
相关申请的交叉引用
本申请要求于2019年6月19日提交、申请号为201910533236.4且名称为“一种可调式柔性截流装置”的中国专利申请的优先权，其全部内容通过引用合并于此。
技术领域
本发明涉及排水系统技术领域，具体涉及一种可调式柔性截流装置。
背景技术
申请号为CN200820044904.4，名称一种气动管夹阀的中国专利公开了一种气动管夹阀，包含阀体、管夹橡胶管，阀体上设有进气口，阀体通过上、下法兰将管夹橡胶管固定安装在阀体内，管夹橡胶管与阀体之间形成充气腔，当充气腔充气时，管夹阀关闭，充气腔放气，管夹阀打开。目前，小口径的管夹橡胶管在气压下可以实现两点变形关闭，大口径(DN400以上)的管夹橡胶管在气压下可以实现三点或四点变形关闭。但不管怎么变形，都是管夹橡胶管两点或多点对称变形，在流道的中间形成完全关闭，阻断水流。此种结构的管夹橡胶管只能实现开启或者完全关闭两种状态。虽然可以通过控制充压大小控制气动管夹阀的开度，但是由于气压作用下的整个管夹橡胶管均处于形变状态，管道截面大小与压力之间的关系很难计算并进行开度控制，也不能控制截流高度，因此，现有技术的气动管夹阀多应用在给水系统中。
在排水系统的分流井、排口、调蓄池入口、截污管等位置处需要进行截流控制或者防倒灌，因此，上述气动管阀阀很难应用在排水系统中。

具体实施方式
下面结合附图及具体实施例对本发明作进一步的详细描述。
实施例1

本实施例1使用状态下，橡胶套筒2的可变形部分位于壳体1的下半部，当可充腔体20充气压或者充水压或充油压时，橡胶套筒2的可变形部分发生形变，根据使用需要，可以充入一定压力的气压或水压或油压，橡胶套筒2的可变形部分可以从底部向上逐渐关闭流通通道，不仅可以控制流通通道的导通和截止，还可以进行流量调节、溢流、防倒灌等，本实施例结构简单，操作方便，功能多样，适用范围广。
本实施例中为调节流通通道10内的流量，可以通过控制橡胶套筒2充气或充水或充油后的高度来控制，从底部拦截流通通道10，其所在位置处的流通通道10的上部保持流通。
本实施例中的可充腔体20充气压或充水压或充油压后，橡胶套筒2的可变形部分相当于溢流堰，当其上游的水流高度超过该橡胶套筒2的拦截高度时，从该橡胶套筒2的顶部溢流到下游，此外，该橡胶套筒2拦截管道底部的积泥或者分流井内的积泥，防止底部的积泥随水流进入自然水体，对自然水体造成污染。且当自然水体液位较高时，还具有防倒灌功能，保证橡胶套筒2的高度高于自然水体的液位高度，此时如上游的水位高于橡胶套筒2的拦截高度时，还可以从橡胶套筒2的顶部溢流至下游，在不影响行洪的情况，进行防倒灌。
本实施例中壳体1为圆筒状结构套设于橡胶套筒2外，流通通道10沿轴向贯穿橡胶套筒2，橡胶套筒2和壳体1同轴线设置，且橡胶套筒2可变形部分为橡胶套筒的下半部分，其他位置处为不可变形。当可充腔体20充介质后，橡胶套筒2的下半部分变形，最大变形位置处，橡胶套筒2下半部分内部与上半部分内壁紧密贴合，流通通道截止。本实施例中的橡胶套筒2为圆筒状结构，结构简单，橡胶套筒2可以整体从壳体1内取出或者安装在壳体1内，方便橡胶套筒2的安装和拆卸。
进一步地，为了实现橡胶套筒2位于可充腔体20位置处的部分可变形，其他位置处不可变形，有以下实现方式，本处进行列举并非穷尽， 具体方式如下：壳体1内壁与橡胶套筒2外壁之间形成套筒状间隙，橡胶套筒2还设有隔挡部21，隔挡部21将橡胶套筒2阻挡为可变形部分和不可变形部分，橡胶套筒2与壳体1同轴线设置，橡胶套筒2的端部与壳体1的端部连接，结构简单，方便操作。
进一步地，隔挡部21为定型内衬21a，参见图1至图5所示，定型内衬21a设于橡胶套筒2不可变形部分处的内表面，或者参见图6所示橡胶套筒2的上半部分包覆定型内衬21a，且定型内衬21a的形状与橡胶套筒2不可变形部分的形状适配。本实施例中的橡胶套筒2为圆筒状，定型内衬21a为半圆筒槽状的钢丝网结构，可以固定在橡胶套筒2的内表面上，也可以通过硫化的方式与橡胶套筒2的上半部硫化，即使橡胶套筒2的上半部的间隙被充入水或气体或充油，由于定型内衬21a为刚性结构，定型内衬21a在压力的作用下也不发生变形，只有下半部的橡胶套筒2发生变形，将定型内衬21a硫化后或者贴合后与橡胶套筒2一起安装，结构简单，方便操作。本实施例中的橡胶套筒2的端部设有外边缘23，壳体1的端部与外边缘23密封连接，其中壳体1包括圆筒状的外套筒14和压套15，外壳体14的端部内侧设有凹槽，橡胶套筒2的外边缘23至于该凹槽内通过外套筒14的端部和压套15密封固定，密封效果好。
进一步地，隔挡部21还可以为定型外衬21b，参见图7和图8所示，定型外衬21b设于橡胶套筒2不可变形部分的外表面，且定型外衬21b的形状与与橡胶套筒2不可变形部分的形状适配。本实施例中的橡胶套筒2为圆筒状，定型外衬21b为半圆筒槽状的钢丝网结构，固定在橡胶套筒2的外表面上，即使橡胶套筒2的上半部的间隙被充入水或气体，由于定型外衬21b为刚性结构，也不发生变形，阻挡上半部的橡胶套筒2与气体或水接触，只有下半部的橡胶套筒2发生变形，将定型外衬21b与上半部分的橡胶套筒2贴合后与橡胶套筒2一起安装，结构简单，方便操作。本实施例中的橡胶套筒2的端部设有外边缘，壳体1的端部与 外边缘23密封连接，其中壳体1包括圆筒状的外套筒14和压套15，外壳体14的端部内侧设有凹槽，橡胶套筒2的外边缘23至于该凹槽内通过外套筒14的端部和压套15密封固定，密封效果好。
本发明的工作原理：本发明实施例1至实施例3的可调柔性截流装置安装在分流井、排口或者管道中，可调柔性截流装置的进口通过输气管道或输水管道与气站或者水站相连，可调柔性截流装置充气或者充水后，橡胶套筒2的可变形部分单向发生形变，从底部向上逐渐升高流通通道10的截面积变小，除可以进行开启或者关闭功能外，还可以根据实际使用需求进行流量调节，控制溢流或者防倒灌等操作。
本领域的技术人员可以对本发明实施例进行各种修改和变型，倘若这些修改和变型在本发明权利要求及其等同技术的范围之内，则这些修改和变型也在本发明的保护范围之内。
说明书中未详细描述的内容为本领域技术人员公知的现有技术。
