Abstract

本发明公开一种用于检测灌溉管道内爆裂的方法。挤压灌溉管道。进一步可通过循环灌溉管道内的空气产生正气压。随着所述正气压输送所述灌溉管道至罐，其中所述罐包括冷却液。进一步将至少一个气泡困于罐表面。

Description

管道/管内爆裂的检测方法和***
技术领域
本文所描述的主题大体涉及管道或管内的爆裂，更具体涉及管道或管内爆裂的检测。
背景技术
爆裂为管道/管内的洞，其一般当挤压物在材料冷却之前进入真空罐水浴的伸展和拉伸期间由挤压物中的异物产生弱或开口区域而导致。
爆裂可为实际上会作用于管道/管并中止生产线的小微穿孔或大洞。停线的大洞容易检测，它们正位于管的中断点。而微小穿孔更难被发现，因为它们会普遍存在于线路而不被检测。客户会在完成灌溉工程并打开水时发现他们。许多在那时检测到的爆裂常常以喷泉或水淹池显示。如果管道/管为埋入式，在通常情况下，挖掘泥土以定位和维修每处爆裂发生地是一项长期工作。由于爆裂很少仅在一处发生，该区域会因它们而弄得乱七八糟，导致客户巨大的工作量和制造商的维修困难。
发明内容
本概述用于介绍涉及在管道/管的制造期间检测爆裂或故障的爆裂检测器的方面。本概述并不旨在标识所要求保护的主题的实质特征，也无意用于确定或限定所请求保护的主题的范围。
在一个实施例中，公开了一种用于检测灌溉管道内爆裂的方法。该方法可包括挤压灌溉管道。进一步，该方法可还包括在灌溉管道内产生正气压。该正气压可通过循环灌溉管道内的空气而产生。该方法可包括随着正气压输送灌溉管道进入罐。该罐可包括冷却液。进一步，该方法可包括将至少一个气泡困于罐表面。
附图说明
参照附图进行详细说明。图中，附图标记中最左边的数字标识该附图标记首次出现在其中的附图。相同的附图标记在所有附图中都指代相同的特征和部件。
图1显示根据本公开的一个方面的用于检测灌溉管道内爆裂的流程图。
图2显示根据本公开的一个方面的爆裂检测器。
具体实施方式
本主题公开了在管道/管的制造期间检测爆裂或故障的爆裂检测器。
爆裂检测方法意味着管道/管内的正气压和真空罐的负压之间的差别。当罐内充满冷却液，管道/管内的正气压沿真空罐的长度方向运动时会穿过缺陷处并产生气泡。该设备当管在其下方运动时捕获一连串气泡并输送(漏斗)它们至其中容许它们冲破冷却液表面的中心区域。气泡冲破小直径管内的表面并由管随着一定量冷却液运输至它们能够由传感器检测的点。输出信号可设定为发出警告、中止生产或任何其他报警形式。
图1显示根据本公开的一个方面的用于检测灌溉管道内爆裂的流程图。流程图100可包括步骤102，其中灌溉管道可由如聚氯乙烯(PVC)的材料压制。在步骤104，灌溉管道内的正气压可通过泵送空气经过灌溉管道而产生。进一步，在步骤106，具有正气压的灌溉管道可被输送进罐。该罐可包括冷却液，其中该罐可完全填充冷却液。由于没有空气，完全填充冷却液的罐可在罐内产生负气压。在步骤108，当灌溉管道被输送进罐，从灌溉管道逃脱的任何气泡或至少一个气泡可困于罐表面。由于灌溉管道具有正气压，罐具有负气压，该至少一个气泡可源于灌溉管道内的爆裂。该困于罐表面的至少一个气泡可进一步通过管道转移至传感器或可直接在表面感测。根据一个示意性实施例，可使用压电传感器或超声传感器。进一步，一旦检测到至少一个气泡，可发送警告给用户或操作者。
图2显示根据本公开的一个方面的爆裂检测器。用于检测爆裂的***200可包括挤压机202。该挤压机可配置为挤压用于灌溉的管道。可以使用任何传统机器实现此目的。该挤压的灌溉管道可进一步输送至罐206。该罐206可填充冷却液204。该***还可包括传感器208。传感器208可经配置用于检测任何经过或通过冷却液至罐表面的气泡。接着，可启动传感器警告***的用户或操作者。
