, 2004 本实用新型公开了一种具有自冲洗功能的抗堵塞滴灌灌水器，包括一普通纽扣式灌水器外壳，灌水器外壳的两端分别有一进水口和出水口，进水口的端口上设置有一过滤网，壳体内的进水口和出水口的通道上，设置有一具有弹性的橡胶内芯，橡胶内芯呈“+”字形状，上下部均为圆柱形，橡胶内芯的中间为片形，灌水器出水口的内侧带有多个梯形流道。其工作过程是当滴灌系统刚启动或关闭后，水流对内芯上的橡胶止水柱产生一定的压力，当压力较小时，内芯变形量不大，所以出水口开度较大，有利于将较大颗粒的堵塞物或杂质冲出 ...

, 2018 电能替代已成为国内城市供暖的主要方向,储热技术可以将谷电以热的形式储存起来并实现热能的稳定输出,从根本上解决电采暖成本过高的问题。中低温相变储热以其储热密度高、储释热过程温度恒定等优势成为研究热点。中低温相变储热材料的研究主要集中于有机石蜡类及无机水合盐类,目前已有应用案例中主要为水合盐类材料,但其仍存在循环稳定性差、导热性差、腐蚀性等问题。在对相变储热装置的实验室研究中,通过设计并联螺旋盘管、填充筛网、壳管式结构等方式可以有效改善相变材料的传热性能,但在实际工程应用中 ...
