相关申请的交叉引用
本申请要求2017年9月5日提交的美国临时专利申请No.62/554,064的优先权和任何权益，其全部内容通过引用合并于此。
技术领域
本发明的总体构思涉及管道隔绝件(pipe insulation)，并且更具体地，涉及更容易顺应要被隔绝的管道的外部形状的管道隔绝件。
背景技术
如图1A所示，一种类型的常规管道隔绝件100形成为隔绝材料104的平坦的板102。纵向v形凹槽106在平坦的板102中切出以形成隔绝材料104的单独的段108。在图1A中，示出了八个段108，即，A1、A2、A3、A4、A5、A6、A7和A8。
可选地，通常在隔绝材料104内切出v型凹槽106之前，可以将正面材料110和/或背衬材料112固定到隔绝材料104。在安装期间，正面材料110将位于隔绝材料104和要被隔绝的管道140之间。在安装期间，背衬材料112将位于离管道140最远的隔绝材料104的外侧。这些材料110、112可以用于多种目的中的任一种，例如用作蒸气屏障或为隔绝材料104的段108增加支撑。
每个段108具有梯形形状。通常，每个段108将具有等腰梯形的形状，具有上基部120和下基部122。上基部120和下基部122通过一对支腿部124连接。上基部120和下基部122彼此平行，而支腿部124彼此不平行。隔绝材料104的厚度126由上基部120和下基部122之间的距离限定。
形成为带凹槽的板(例如，如图1D所示的带凹槽的板102)的管道隔绝件100是理想的，因为与形成为细长圆柱体的管道隔绝件相比，其可更容易和/或更便宜地制造、运输和/或存储。此外，形成为带凹槽的板的管道隔绝件100通常比圆柱形形式的管道隔绝件更通用，因为这种圆柱体仅用于隔绝特定尺寸的管道。
上述的v形凹槽106允许操作板102，使得相邻段108的支腿部124彼此抵接，从而闭合位于相邻段108之间的v形凹槽106。以这种方式，平坦的板102变换成隔绝材料104的细长的空心多边形，该多边形具有n个边，其中n是形成该多边形的段108的数量。
在安装期间，板102通常围绕要被隔绝的管道140缠绕，直到隔绝材料104完全围绕管道140为止。此后，板102的围绕管道140的部分可以与板102的其余部分分开，并且被密封以保持其形状。以此方式，形成了多边形隔绝构件，该多边形隔绝构件具有包围管道140所需的最少的边数。
例如，如图1B所示，管道隔绝件100由转变成六边形隔绝构件130的板102表示。隔绝构件130是由六个隔绝材料104的段108(即A1、A2、A3、A4、A5和A6)形成的细长的空心多边形。隔绝构件130包括用于容纳要被隔绝构件130隔绝的管道140的内腔132。
因为隔绝材料104是基本上刚性的(即，抵抗变形)，所以隔绝构件130的腔132必须比所需的大，以便完全围绕管道140。这可以在图1C中看到，其中管道140的外表面最接近隔绝材料104的段108的中点150，并且管道140的外表面距形成在彼此抵接的隔绝材料104的相邻段108处的拐角152最远。因此，在管道140的外表面和隔绝构件130的内表面之间产生了显著的间隙160。在图1C中，具有六个这样的间隙160，即在相应的拐角152处。
这些间隙160不利于管道隔绝件100，因为间隙160降低了隔绝构件130相对于管道140的隔绝能力，并且充当了水分在管道隔绝件100内凝结和行进的路径。如果存在从管道140的外表面延伸的突起或其他相关结构(例如，法兰、阀)，则可能会加剧这种情况。
因此，迫切需要形成为如下平坦的带凹槽的板的管道隔绝件，该管道隔绝件在将管道隔绝件安装在管道上期间更容易地与管道(例如，管道140)的外表面相顺应。
发明内容
本文中提出了提供更容易顺应于(conform)要被隔绝的管道(和任何附带的配件)的外部形状的管道隔绝件。
因此，总的发明构思涉及并考虑了形成为平板状构件的管道隔绝件，以及用于制造管道隔绝件的方法和系统。管道隔绝件具有比第二区域更可压缩的第一区域。
根据以下示例性实施例的详细描述、权利要求书以及一起提交的附图，本发明总体构思的许多其他方面、优点和/或特征将变得更加显而易见。

具体实施方式
尽管该总体发明构思可以以许多不同的形式实施，但是在附图中示出并且将在本文中详细描述其特定的实施方式，应理解，本公开应被认为是该总体发明构思的原理的示例。因此，该总体发明构思不旨在限于本文所示的特定实施例。
本公开的总体发明构思包括改进的管道隔绝件。管道隔绝件形成为平坦的带凹槽的板，其在将管道隔绝件安装在管道上期间更容易顺应管道的外表面。
总体而言，该改进的管道隔绝件可以消除或以其他方式减少手动移除一部分隔绝材料以适应延伸超过待被隔绝的管道的外周的突出部的需要。
总体而言，该改进的管道隔绝件可以增加将管道隔绝件安装在要被隔绝的管道上的便利性。
总体而言，该改进的管道隔绝件可以提高将管道隔绝件安装在要被隔绝的管道上的速度。
总体而言，该改进的管道隔绝件可以消除或以其他方式减少隔绝材料与要被隔绝的管道之间的间隙的存在。
将参照图2A-2D描述改进的管道隔绝件200的示例性实施例。如图2A所示，管道隔绝件200形成为隔绝材料204的平坦的板202。隔绝材料204通常是纤维隔绝材料，例如玻璃纤维隔绝材料或矿棉隔绝材料。纵向v形凹槽206被在板202中切出以形成隔绝材料204的分离的段208。在图2A中，示出了八个段208，即，B1、B2、B3、B4、B5、B6、B7和B8。
可选地，通常在将v形凹槽206在隔绝材料204中切出之前，可以将正面材料210和/或背衬材料212固定至隔绝材料204。在安装期间，正面材料210将位于隔绝材料204和要隔绝的管道140之间。在安装期间，背衬材料212将位于离管道140最远的隔绝材料204的外侧。这些材料210、212可以用于多种目的中的任一种，例如充当蒸气屏障或为隔绝材料204的段208添加支撑。
每个段208具有梯形形状。通常，每个段208将具有等腰梯形的形状，具有上基部220和下基部222。上基部220和下基部222通过一对支腿部224连接。上基部220和下基部底部222彼此平行，而支腿部224彼此不平行。隔绝材料204的厚度226由上基部220和下基部222之间的距离限定。
在形成为平坦的带凹槽的板的常规管道隔绝件(例如，管道隔绝件100)中，隔绝材料104在其整个厚度126上是基本上刚性的。相反，在形成为平坦的带凹槽的板的管道隔绝件200中，隔绝材料204在其整个厚度226上不是基本上刚性的。相反，隔绝材料204在其整个厚度226上具有非均一的构成。将参照图2B所示的单个段208进一步描述该非均一的构成。
特别地，隔绝材料204的代表性的段208包括第一隔绝材料的内部区域280和第二隔绝材料的外部区域282。内部区域280从上基部220延伸到外部区域282。外部区域282从下基部222延伸到内部区域280。
管道隔绝件200的厚度226等于内部区域280的厚度t1和外部区域282的厚度t2之和。在一些示例性实施例中，内部区域280的厚度t1小于厚度外部区域282的t2。在一些示例性实施例中，内部区域280的厚度t1等于外部区域282的厚度t2。在一些示例性实施例中，内部区域280的厚度t1大于厚度外部区域282的t2。
在一些示例性实施例中，内部区域280的厚度t1是管道隔绝件200的总厚度226的至少10％。在一些示例性实施例中，内部区域280的厚度t1是管道隔绝件200的总厚度226的至少20％。在一些示例性实施例中，内部区域280的厚度t1是管道隔绝件200的总厚度226的至少30％。在一些示例性实施例中，内部区域280的厚度t1为管道隔绝件200的总厚度226的至少40％。在一些示例性实施例中，内部区域280的厚度t1为管道隔绝件200的总厚度226的至少50％。
虽然隔绝材料的外部区域282可以是刚性的(例如，类似于常规管道隔绝件100的隔绝材料104)，但是隔绝材料的内部区域280不是刚性的。特别地，内部区域280的隔绝材料的刚性小于外部区域282的隔绝材料的刚性。换句话说，内部区域280的隔绝材料比外部区域282的隔绝材料可压缩性更高。可以控制各种属性以减小内部区域280的隔绝材料的刚性，包括例如隔绝材料的密度、构成隔绝材料的纤维的直径、隔绝材料上的粘合剂(LOI)的量、以及隔绝材料上的粘合剂类型。因此，在安装时，管道隔绝件200更容易围绕管道以及从管道140的外表面延伸或从管道140的外表面附近延伸的任何配件、突起或其他结构(例如，法兰、阀)而安装。
如同传统的管道隔绝件100那样，上述的v形凹槽206允许对板202进行操作，以使得彼此相邻的段208的支脚部224彼此抵接，从而闭合位于相邻段208之间的v形凹槽206。以这种方式，将平坦的板202转变成隔绝材料204的细长的空心多边形，该多边形具有n个边，其中n是形成该多边形的段208的数量。
在安装过程中，通常将板202绕要被隔绝的管道140缠绕，直到隔绝材料204完全围绕管道140。此后，板202的围绕管道140的部分可以与板202的其余部分分开，并被密封以保持其形状。当然，板202的宽度可以选择或以其他方式预先计算以匹配要隔绝的管道140的尺寸。以此方式，形成了多边形隔绝构件，该多边形隔绝构件具有围绕管道140所需的最少的边数。
例如，如图2C所示，通过将板202转变成六边形隔绝构件230来表示管道隔绝件200。隔绝构件230是由六个隔绝材料204的段208(即B1、B2、B3、B4、B5和B6)形成的细长的空心多边形。隔绝构件230包括内腔232，用于容纳要由隔绝构件230隔绝的管道140。
因为隔绝材料204的内部区域280不是基本上刚性的，所以隔绝构件230的腔232可以更紧密地接近管道140的外圆周142。这可以在图2C中看到，其中管道140的外圆周142(以虚线示出)能够延伸到隔绝材料204的内部区域280中。换句话说，管道140的外圆周142可以延伸超过隔绝材料204的段208的中点250。同样地，管道140的外圆周142可以更紧密地接近(或甚至延伸超过)形成在隔绝材料204的相邻段208彼此抵接之处的拐角252。在一些示例性实施例中，管道140的外圆周142限定了延伸通过隔绝构件230的大部分内拐角252的圆。结果，如图2D所示，与传统的管道隔绝件可见的间隙(例如，间隙160)相比，在管道140的外表面和隔绝构件230的内表面之间的任何间隙260都被显著地减小(如果没有消除的话)。
此外，因为隔绝材料204的内部区域280是可压缩的，所以隔绝构件230的腔232可以更容易地顺应配件、突起或延伸到管道140的外圆周142之外的其他结构(例如，凸缘、阀)。这样就避免了常规管道隔绝件的问题，即必须使用比包围管道所需的更大的隔绝构件以适应配件，这是浪费的并且在隔绝构件与管道隔绝件之间产生了不希望有的间隙。换句话说，鉴于其增强的顺应性，与传统的管道隔绝件(例如，管道隔绝件100)相比，管道隔绝件200能够以包括更少的段(例如，更低的n值)的隔绝构件围绕管道140。此外，鉴于其增强的顺应性，管道隔绝件200可以能够围绕管道140及其配件而无需移除任何隔绝材料204。
总体发明构思还包括用于制造本文公开或以其他方式建议的本发明的管道隔绝件的方法和系统。例如，已知使用多个喷丝头来形成纤维隔绝板。如上所述，可以控制各种属性以减小本文所述的本发明的隔绝板的一部分中的隔绝材料的刚性。这些属性包括但不限于隔绝材料的密度、构成隔绝材料的纤维的直径、隔绝材料上的粘合剂(LOI)的量、以及隔绝材料上的粘合剂的类型。因此，当板沿着生产线向下运动时，可以使用不同的喷丝头来改变这些属性。
总体发明构思的范围不旨在限于本文中示出和描述的特定示例性实施例。从给出的公开中，本领域技术人员将不仅理解总体发明构思及其伴随的优点，而且还将发现对所公开的方法和系统的显而易见的各种改变和修改。因此，力求覆盖落入本文所述和所要求保护的总体发明构思的精神和范围之内的所有这些改变和修改及其任何等同形式。
