Abstract

本实用新型公开了一种自动翻转阀，主要由阀壳(1)、导轨(2)、导轮(3)、阀门(4)、翻转轮(5)、摆臂(6)、摆臂回转轴(7)、盖板(8)、连接螺栓(9)组成。矿浆输送渣浆泵(一备一用)中的任意一台泵需停机检修另一台开动时，阀门(4)在矿浆压力作用下，通过摆臂(6)绕摆臂回转轴(7)公转，当阀门(4)背面碰到翻转轮(5)时，翻转轮(5)给阀门(4)一回转力矩，使得阀门(4)绕摆臂(6)上的回转轴自转，当阀门(4)转至水平位置时，导轮(3)已进入导轨(2)中，在矿浆压力及自身惯性作用下持续自转和公转，当阀门(4)自转180°时，阀门4工作面盖住管口，实现管道的自动开启和关闭。

Description

一种自动翻转阀
技术领域
本实用新型涉及一种用在选矿厂矿浆输送渣浆泵(一备一用)管道自动开启或关闭阀门。 
背景技术
现选矿厂矿浆输送渣浆泵(一备一用)管道的开、关用阀门有如下几种型式：1-泰勒球阀(自动开、关)，2-手动、气动、电动闸阀。对于泰勒球阀，因阀体是球形，它在阀腔内可任意转动，其密封面不确定，阀体在矿浆的冲刷下表面很快磨得凹凸不平，导致关闭不严，一般寿命2-3个月。对于手动、气动、电动闸阀因其结构复杂，成本高，需人力或其它动力操作，故现选矿厂上述两种阀都在使用，各有利弊。 
发明内容
本实用新型提供一种选矿厂矿浆输送渣浆泵(一备一用)管道自动开启或关闭阀门。它由阀壳1、导轨2、导轮3、阀门4、翻转轮5、摆臂6、摆臂回转轴7、盖板8、连接螺栓9等零部件组成。其特征是：摆臂回转轴7一端固定在阀壳1上，摆臂6套在摆臂回转轴7上，摆臂回转轴7另一端设一阀门4回转轴，阀门4套在该回转轴上，阀门4上端靠两侧对称偏置两导轮3，导轨2、翻转轮5连接在盖板8上，盖板8通过连接螺栓9与阀壳1连接成一体。 
矿浆输送渣浆泵(一备一用)中的任意一台泵需停机检修另一台开动时，阀门4在矿浆压力作用下，通过摆臂6绕摆臂回转轴7公转，当阀门4背面(非密封面)碰到翻转轮5时，翻转轮5给阀门4一回转力矩，使得阀门4绕摆臂6上的回转轴自转，当阀门4转至水平所示位置时，导轮3已进入导轨2中，阀 门4在矿浆压力及自身惯性作用下持续自转和公转，当阀门4自转180°时，阀门4工作面盖住管口，实现管道的自动开启和关闭，阀门4工作面工作状态下不受矿浆的冲蚀磨损，大大提高了阀的密封可靠性和寿命。 
附图说明

具体实施方式
上述自动翻转阀装配关系就是本实用新型实施方式，其生产装配关系是：摆臂回转轴7一端固定在阀壳1上，摆臂6套在摆臂回转轴7上，摆臂回转轴7另一端设一阀门4回转轴，阀门4套在该回转轴上，阀门4上端靠两侧对称偏置两导轮3，导轨2、翻转轮5连接在盖板8上，盖板8通过连接螺栓9与阀壳1连接成一体。
