Abstract
一种用于局部灌溉的用后即可随意处理的喷灌 管路由一根带有等距离孔的软管构成，还有借助于 上3孔附近焊点粘附在上述软管内壁的内柔性膜片， 膜片和软管内壁在有水流的情况下形成间隙；在内 膜片上有切口。这些切口同样位于有规则的间隔的、 相对于外软管的孔交错位置。在两个相邻焊点之间 至少有一个外孔。至少有一个内切口相应于外孔。
Description
本发明涉及一种用于农田局部灌溉的装置，这种装置由一个用后即可随意处理的喷灌管路构成。该喷灌管路由一个外软管和一个内柔性膜片组成。
在农业上，喷灌管路用于灌溉目的。在喷灌管路中，液体进口的开口沿着用一根管路分布，保证要进行浇水的农田基本上均匀地得到浇湿。
在众多的喷灌管路中，用后即可随意处理型是只使用一个季节的型式，用完后即被拆除，可能和收获的植物一起去掉，然后被破坏。
上述管路构成了一个较完整的灌溉系统，在该系统中，它们联接在一个供给水的干线上。
一般使用的系统包括一个小截面盘旋管，以产生足够高的压降，使液体从管道中以珠状形式济出（英国专利No1，286，538和1，484，588）。但是，由于有真空阀被堵塞的危险的缺点以及由于压力变化，特别是地面与水平面有差距时，在单个真空阀流动速率的变化，这种装置的效果即受到影响。
用于由在其内部配备一个或多个弹性膜片构成的珠状灌溉装置同样也是公知的（美国专利No4，009，832和意大利专利申请No23，763A/79）。尽管这些装置没有上面提及的缺点，但它们同样也不总是能保证均匀地浇水，这是由于内膜片对管道内壁没有良好的粘附作用。
现在我们已经发现，也就是本发明的目的，即有可能实现一种用于用后即可随意处理型的局部灌溉的喷灌管路。这种喷灌管路保证均匀地浇水，同时还避免了堵塞的任何危险。
本专利申请主题的用后即可随意处理的喷灌管路由一个在长度方向上互相等距离布置孔的软管构成，在其内部包含粘附在软管内壁的柔性膜片，并把其沿整个圆周焊接，使之能够在有水流的情况下与壁形成间隙。软管的每个孔位于上述间隙之间。膜片在间隙内部相对于软管孔交错位置上，依次配有至少一个切口。
附图表示一个本发明喷灌管路的最佳实施例。在附图中：
图1喷灌器的横向截面图;
图1a是柔性膜片的细节图，同样为横向截面图;
图2是整个喷灌器长度方向截面图。
在这些图中，软管（A）的壁，内膜片（C），软管孔（B）、切口（E）、间隙（F）和焊点（D）是已知的。
参照上述附图，本发明主题的喷灌管路在此处由一个柔性热塑树脂的软管A构成。在软管A长度方向上同等距离地开有孔B。在上述软管内部有柔性膜片C。该柔性膜片C同样也是由热塑材料制成，粘附在软管的内壁上并借助于沿每个膜片整个圆周的焊点D粘接在软管上。在粘接后，膜片内至少有一个软管孔。每个膜片在相对于软管孔交错位置上有一个切口E位于孔的内部，与间隙F沟通。该间隙F在膜片后和同一软管内壁之间在有水流的情况下形成。
这样，从孔的内部到外部环境的一个通道由下述部分形成：
-在膜片上的切口，
-在膜片和软管之间形成的间隙，
-在软管上的孔。
通过间隙的通道由膜片粘附在软管壁上被堵塞，由存在于同一软管内部的压力固定位，使接头水流为珠状形式。
软管内部和间隙之间在一定压力降时产生通道是非常必要的。如由小切口精确地产生的压力降，以保证膜片粘附在软管内壁。其它位置喷射将沿软管第一部分发生，这种喷射可以防止软管胀大以及调整操作。
在靠近切口和孔的地方，膜片的粘附将靠其端部的联接来帮助，这种联接在一侧非常靠近切口而在相对侧靠近孔。
膜片上的切口最好在相应的同一间隙内具有和软管上孔的直径相等的尺寸。
如上所述，软管由以烯族聚合物，乙烯基聚合物，聚酰胺，聚酯树脂等以及其混合物制成，还可以由两种或更多的上述材料共同挤压制成。膜片可以依次由和软管材料相同的材料制成或由相当于这些材料的材料制成。
上述材料可以用其纯洁材料，或者可以和能够修正水滴和聚合物接触角的亲水性物质适当地化合，这样就可以控制水流速率的变化，可以使用的物质有含氮化合物，如酰胺、铵盐、氧化乙烯副产品。
上述控制的可能性可以由添加剂的存在而加强，添加剂由增粘剂型物质构成，如从苯乙烯衍生物，2-甲基丁二烯衍生物或乙烯共聚物中选用。
下面的实例图示3本发明的喷灌管路，但并不是限定本发明目的的结构。
实例
采用高密度聚乙烯软管，内径为17mm，壁厚为0.1mm，孔径4mm，配备相同材料和厚度的内膜片，配备一个5mm长的切口，和孔离开50mm，这样即可获得珠状分布，每个水流孔流动速率约为0.35升/小时。
