Description

一种挡板阀结构
技术领域
本发明属于机电技术领域，具体涉及一种挡板阀结构。
背景技术
安装顺序增压系统的发动机，压气机控制阀一般布置在压气机的进口，有利于工作温度较低，方便切断空气。
但是，这种结构的压气机控制阀打开的情况下，阀板会造成进气节流，影响顺序增压系统的效率；
还有，现有的结构往往在阀轴处设计了多层填料结构，由于阀轴与填料的摩擦，导致阀门的驱动力矩大，不满足顺序增压系统对高温阀的低驱动力矩要求。
发明内容
有鉴于此，本发明旨在提出一种挡板阀结构，既能在阀门关闭时可靠地密封，又能在阀门开启时降低阀板对空气的阻力，不影响发动机的进气。
为达到上述目的，本发明的技术方案是这样实现的：
一种挡板阀结构，包括阀体、阀板和轴，所述阀体的左右两端分别设有进口法兰和出口法兰；所述阀体内部的底面为平面结构，在进口法兰的内侧面与底面的交界处安装所述轴，所述阀体的对应位置上设有用于安装所述轴的轴孔；所述阀板的底端固定安装在轴上，可随着轴进行旋转；所述阀体左端内侧面上设有与阀板关闭时配合的环形的第一密封带，所述阀板上设有与第一密封带配合的第二密封带。
进一步的，所述轴的左右两端分别通过一个嵌套轴承结构安装在所述阀体的对应位置上的轴孔内；
所述嵌套轴承结构包括嵌套设置的外对开环和内对开环，所述外对开环为两个半圆形的环，形成封闭的圆环结构，所述圆环结构的外圈为圆柱面，内圈为凹的锥形槽；所述内对开环为两个半圆形的环，形成封闭的圆环结构，所述圆环结构的内圈为圆柱面，外圈为凸的圆环锥形体；所述内对开环的圆环锥形体嵌入所述外对开环的锥形槽内；
所述内对开环嵌入所述轴对应位置上设置的环槽内，所述外对开环嵌入阀体对应位置上设置的台阶孔处；所述阀体的左右两端的轴孔外端均设有限位所述嵌套轴承结构的封盖，所述外对开环与封盖之间设有压紧环。
进一步的，所述轴一侧上的环槽宽度大于嵌入其内的内对开环的宽度，使内对开环可以在其环槽内左右移动；所述轴另一侧的端部固定连接头。
进一步的，所述阀板由第二密封带包围的部分的形状为球面，球面的外侧朝向阀体结构的进口，为压力面；所述压力面上有加强筋。
进一步的，所述阀体的截面呈拱形，所述阀板呈拱形，竖直放置时与所述阀体的拱形截面配合。
相对于现有技术，本发明具有以下优势：
(1)本发明能在阀门关闭时可靠地密封，同时由于阀板水平放置时，阀板与底面完全贴合，阀板完全不影响阀门的流通通道，所以这种阀门适合于顺序增压发动机的压气机进气控制阀形式，对于降低发动机进气阻力效果明显。
(2)本发明支撑轴的嵌套轴承结构只有内对开环凸出的圆环锥形体与外对开环的凹的锥形槽的接触，接触面积小，在阀门开闭时降低阀门的驱动力矩。
