技术介绍
喷灌、微灌等现代农业节水灌溉新技术,都离不开输配水管路系统,而压力——流量调节设备则是该系统重要的配套设备。目前,我国在管路灌溉作业中,由于缺乏压力——流量调节设备,当管路系统支管入口处的压力过高需要适当调低时,只好采用在支管入口端设置“水阻管”(即管径小于支管的一段管子)或减小阀门开度的办法加以调整,这些办法虽然可以调节压力和流量,但存在着上游压力发生变化时,下游的压力和流量仍会随之产生相应变化,“水阻管”设计调试、阀门启闭费工费时费事的问题。为了解决“水阻管”和阀门调压效果差、劳动强度大的问题,《节水农业新技术研究》公开了一种“调压给水栓”和一种“微灌用压力——流量调节器”。“调压给水栓”是通过阀芯在斜三通阀体内壁卡口内缘上的移动,来调整阀芯表面曲线过流孔的大小,而实现压力——流量调节的;“微灌用压力——流量调节器”是通过调压组件在阀壳内壁卡口内缘上的移动,来调整调压组件小端与进口花篮堵头下游端面之间过流间隙的大小,而实现压力——流量调节的。上述 ...
