Description

弹性阀板翻板阀
技术领域
本发明涉及一种具有较好密封性的翻板阀，适用于块状、粉状物料分配切断。
背景技术
目前使用的翻板阀通常采用刚性阀板，与阀板对应的阀座也是刚性，因此阀门在关闭时由于存在制造精度、装配精度以及夹料等问题，使得阀板与阀板座之间产生点接触，而非面接触，造成阀板与阀座之间出现缝隙，使得阀门不能严密关闭，导致物料泄漏。
发明内容
发明目的：本发明的目的是针对现有技术问题，提供一种阀板具有弹性补偿能力的翻板阀。
为了实现上述目的，本发明采用了如下的技术方案：一种弹性阀板翻板阀，包括阀座，所述阀座上开设有物料口，所述物料口设有可活动的阀板，所述阀板包括支撑板、密封板和弹簧组，所述支撑板与阀座转动连接，所述密封板通过弹簧组与支撑板连接。
本发明中，优选的，所述弹簧组呈矩形整列排布。
本发明中，优选的，支撑板上开设有减重孔。
有益效果：本发明翻板阀阀板采用弹性补偿原理，可实现阀板密封面的位移补偿，使得阀板与阀座形成面接触，最终达到较好的密封效果。

图3为图2中A向视图；
图4为本发明翻板阀结构示意图；

图6为图5中A向视图。
图中：1-阀座，2-物料口，3-支撑板，4-密封板，5-弹簧组，6-减重孔。
具体实施方式：
下面结合附图对本发明做更进一步的解释。
如图4至6所示，以三通翻板阀为例，本发明的弹性阀板翻板阀包括阀座1，阀座1左、右两边分别开设有一个物料口2，在两个物料口2内侧设有一个可活动的阀板，阀板包括支撑板3、密封板4和弹簧组5，支撑板3端部通过销轴与阀座1转动连接，密封板4设置在支撑板3左、右两侧，密封板4通过弹簧组5与支撑板3连接，弹簧组5呈矩形整列排布，其中，支撑板3用于传递运动，弹簧组5实现位移补偿，密封板4实现阀门密封，为了减轻阀板整体质量，保证其灵活性，支撑板3上开设有四个减重孔6。
当支撑板3向左转动至左侧密封板4与阀座1接触时，左边物料口2关闭，右边物料口2开启，当支撑板3向右转动至右侧密封板4与阀座1接触时，右边物料口2关闭，左边物料口2开启。当密封板4和阀座1接触时，如果密封板4或阀座1存在制造精度、装配精度以及夹料等问题，会使得密封板4某一处与阀座1之间首先产生点接触，随后密封板4其他位置能够在弹簧组5各点弹簧压缩量不同状况下进行位移补偿，进一步实现密封板4与阀座1的面接触，达到较好的密封效果。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
