一种灌溉用PVC伸缩出水口
本技术涉及农田浇灌出水口技术设备领域,尤其涉及一种灌溉用PVC伸缩出水口。
技术介绍
目前农作物的灌溉方式主要有喷灌、滴灌和管灌。当前使用的出水口是裸露在地面上的铸铁出水口、PVC出水口、玻璃钢出水口。这类出水口设计复杂,出水口与保护墩均设置在地面上,保护墩外还留有接口,不仅不容易操作,而且还容易漏水,同时机械化作业很容易损坏,维修率高。在浇灌过程中,不容易封堵,使用很不方便。并且这种铸铁出水口易腐蚀,使用寿命短。同时不便于隐藏,易被盗,在不需要浇灌时,还会占用耕地,不利于耕地的旋耕等其他工作。同时在气温较低的冬季时,由于PVC出水口裸露于地面上,会导致出水口变脆、容易损坏出水口。
技术实现思路
本技术的目的在于克服当前的灌溉用出水口结构复杂、出水口裸露在地面以上、容易受损,同时不便于其他耕种工作的问题,而提供一种灌溉用PVC伸缩出水口,该灌溉用PVC伸缩出水口能够结构简单、密封性能好,在浇灌过程中出水口能够隐蔽式伸缩,易封堵且不占用耕地,浇灌效果好,操作简单、节约劳动力。本技术是这样实现的:一种灌溉用PVC伸缩出水口,包括连接管和安装于连接管上方的外套管,所述外套管与连接管相互连通,所述外套管内壁的上、下两端分别设置有挡环和密封圈,所述密封圈设置于挡环内侧,所述外套管外壁的上端设有外螺纹;所述外套管内设置有能够沿外套管上下移动的出水管,出水管外壁设置有定位环,所述出水管上端与外套管上端平齐,所述外套管上端套装有旋紧盖,所述旋紧盖内侧壁设有与所述外螺纹相匹配的内螺纹,所述旋紧盖内侧壁设置有用于容纳所述出水管上端管壁的环状凹槽。上述的一种 ...
