Abstract

本实用新型涉及一种高效条缝滤水片,由条缝、 垫脚、筋条组成,其中条缝形状为梯形,背面设有垫 脚,每条缝之间由筋条连接,该滤水片结构简单,工艺 性好,出水率高,可广泛用于粉细砂水质层滤水。

Description

本实用新型涉及一种水井用滤水装置,是一种高效条缝滤水片,属于水井设备技术领域。
现在,常规水井所用滤水装置多为水管穿孔缠丝、钢筋棕毛捆绑、混凝土骨架竹片滤水,这些滤水装置普遍存在着出水率低、材料耗用大、成本高,安装复杂等缺点。
为克服以上滤水装置的不足之处,本发明人申请了一种“开窗式条缝滤水管”实用新型专利(申请号:92241538.2),它虽具有结构简单、成本低、出水率高等优点,但在粉细砂水质层中,其出水率亦受到很大影响,为适合在粉细砂水质层中使用,本实用新型提供一种高效条缝滤水片,其有效孔隙率达70%左右,出水率达70%。
本实用新型的构思是利用条缝结构的最大出水特点,将其设计成一个整体包附在钢性骨架管上,条缝为梯形,背面有若干垫脚,还有联接各条缝的筋条。
图1、2为本实用新型结构图。
下面结构附图来说明一下本实用新型,它是由条缝(1)、垫脚(2)、筋条(3)等组成,条缝(1)为梯形,两条缝间距为0.1~0.8cm,条缝(1)背面设有垫脚(2),使滤水片与钢性骨架管之间保持一些空隙,每隔3~5个垫脚(2)还有连接各条缝(1)的筋条(3),以增强滤水片的抗压强度。在本实施例中,滤水片采用聚丙乙烯塑料,条缝间距为0.2cm,与钢性骨架管空隙为0.1~0.9cm左右,条缝长80~120cm。
本实用新型的特点为结构简单、工艺性好、成本低、出水率高,特别适合粉细砂水质层滤水,可广泛用于常规水井滤水装置。
