一种流量可调压力补偿式灌水器
本技术涉及节水灌溉的
,具体涉及一种流量可调压力补偿式灌水器。
技术介绍
目前,丘陵山区林木灌溉存在三个问题:一是丘陵山区地形复杂、坡度大,灌溉系统压力不均,导致灌水均匀性差;二是灌溉用水以地表水为主,含有固体颗粒、微生物等杂质,滴头堵塞非常严重;三是作物在不同生长时期的需水量不同,因此需要不同流量的灌水器。现有技术中灌水器改变流量只能更换灌水器。因此开发一种适用于丘陵山区林木灌溉的灌水器成为亟待解决的问题。申请号为201610532350.1的一项专利技术专利:一种出口流量均匀自调的防堵塞压力补偿灌水器,这种灌水器的流量包括基座、壳体,压力补偿垫片和调节针,压力补偿垫片是用来实现压力补偿功能的,而流量的改变是通过更换不同粗细的调节针实现的。这种灌水器虽然能够实现压力补偿功能,但对流量可调不是很有效,实现的流量调节范围小,不能实现多种额定流量的快速可靠调节。
技术实现思路
针对上述现有技术存在的问题与不足,本专利技术的目的在于提供一种灌水均匀度高、堵塞可清洗、流量可调的压力补偿式灌水器,特别适用于丘陵山区经济林等作物的灌溉。为了实现上述目的,本技术采取如下的技术解决方案:一种流量可调压力补偿式灌水器,包括上盖、压力补偿垫片和下座,所述的上盖以可拆卸方式与下座连接;所述的下座设有灌水器进水口和过滤网;所述的上盖设有出水口;所述的上盖内部底面设置辅助出水流道;所述的灌水器内设有消能环,所述的消能环位于上盖与下座之间形成的空腔内,消能环安装在上盖的内腔中,消能环的外表面与上盖的内腔面相配;所述的压力补偿式垫片位于消能环的内腔的台阶 ...
