Description

教学用可视透明平行式闸阀
技术领域
本发明属于教学演示实验设备领域，涉及教学演示用阀门，特别涉及一种教学用可视透明平行式闸阀。
背景技术
闸阀是一个启闭件闸板，闸板的运动方向与流体方向相垂直，闸阀只能作全开和全关，闸阀关闭时，密封面可以只依靠介质压力来密封，即只依靠介质压力将闸板的密封面压向另一侧的阀座来保证密封面的密封，这就是自密封。大部分闸阀是采用强制密封的，即阀门关闭时，要依靠外力强行将闸板压向阀座，以保证密封面的密封性。
闸阀具有流动阻力小、启闭时较省力、介质可向两个任意方向流动、易于安装、形体简单、工艺性好、结构长度较小等优点，这也使得闸阀实用范围非常广。
但是，工业应用的闸阀一般都是不锈钢材质制成，对于闸阀内部介质的流动方向我们是看不到的，因此在教师教学演示时，不能够清楚直观的让学生看到闸阀内部介质的流向及工作原理，不便于学生理解学习。
因此，在教学过程中，为了让学生更好地观察闸阀内部结构、闸阀的开闭及介质的流动过程，加深对闸阀工作原理的理解，需要设计一种能够可视化的教学演示装置。
通过对公开专利文献的检索，并未发现与本专利申请相同的公开专利文献。
