Abstract

一種管系統包含一流體輸送管、包圍著該管之一第一護套、包圍著該第二護套之一第一護套。該第二護套包含沿周向設置於該第二護套之一內側面上的複數縱向延伸的肋。

Description

管系統及其形成方法
本發明係關於一種用於在建築物內安裝的管系統，尤其是在不通風區域。
撓性氣體管路（Flexible gas piping，FGP），也稱為波紋狀不銹鋼管（corrugated stainless steel tubing，CSST），利用以輥筒（roll）或盤管（coil）形式提供的不銹鋼波紋管與現場連接配件，以將來自一中央供應點（例如儀表或調節器）的氣體分配到房屋或建築物內的各式電器。這項技術（給房屋裝管路的過程比擬為給房屋佈線電力的過程）實際降低了安裝時間並因此相關的勞動力的成本較高。
本領域中存在的管道容納系統，以在管道洩漏時容納流體。一種現有的管道容納系統揭露在美國發明專利號7,004,510中，其全部內容通過引用併入本文。美國發明專利號7,004,510的管道容納系統使用一種套管，其適用於地下設施。需要不同類型的管道系統，用於建築物內的安裝，特別是在不通風區域。
本發明之一目的在於提供一種管系統，其包含：一流體輸送管、一第一護套以及一第二護套。流體輸送管包含多個波峰與多個波谷之一波狀外表面。第一護套包圍該管，而第二護套包圍該第一護套。該第二護套包含沿周向設置於該第二護套之一內側面上的複數縱向延伸的肋。
本發明之另一目的在於提供一種形成該管系統之方法，其包含：使一第一護套突出於該管，該管包含多個波峰與多個波谷之一波狀外表面；使一第二護套突出於該第一護套；其中該第二護套包含沿周向設置於該第二護套之一內側面上的複數縱向延伸的肋
第1圖係一管系統10的局部剖面之側視圖。管系統10包含容納在一第一護套14內之一管12。該管12可以是由金屬製成，並且在本實施例中，呈波紋狀不鏽鋼管。管12也可以是螺旋纏繞管，管12可以是不鏽鋼以外的金屬所製成。管12具有多個波峰與多個波谷之一波狀外表面。
一第一護套14包圍管12。第一護套14可以突出於管12。第一護套14具有通常光滑的圓柱形內外表面。第一護套14可以由熱塑性塑料製成，例如以大約0.030英寸的厚度擠出的低密度聚乙烯（low-density polyethylene，LDPE）。第一護套可以包含阻燃器。
一第二護套16包圍第一護套14。第二護套16可以突出於第一護套14。如此一來，管12、第一套管14以及第二套管16界定一完整的管系統。第二護套16具有通常光滑的圓柱形外表面。第二套管16之內側面包含周向間隔開的肋20（第2圖），其沿第二套管16之內側面之縱向軸心界定出複數通道之複數凹槽。第二套管16可以由熱塑性塑料製成，例如以大約0.030英寸的厚度擠出的低密度聚乙烯（LDPE）。第二護套可以包含阻燃器。
第2圖之剖面圖得自沿第1圖之線段2-2。如第2圖所示，第二護套16之內徑包含多個肋20，肋20由在第二護套之內側面上周向間隔的數個通道所分開。用於將第二護套16突出於第一護套14的模具可以包含複數突起，以形成複數肋20以及複數插入通道。於管12洩漏的情況下，流體沿著複數肋20之間的通道行流動，以在第二護套16之端部處排放。
一線繩18（string）可以放置在第一套管14與第二套管16之間。線繩18可以沿管12之整體長度延伸。當線繩18被拉動，線繩18切穿第二套管16，並且有助於第二套管16的移除而不會移除或以其他方式損壞到第一套管14。
一配件42可以固定至管12之一端。可以使用現有的配件，例如自OmegaFlex公司獲得AutoFlare TM配件。可選的膠帶40，例如自溶性矽酮膠帶（self-amalgamating silicone tape），可以從配件延伸到管12，這裡的符號需要這樣的密封件。
在第二套管16之內側面上的複數通道允許管道12和第一套管14逸出的流體沿著第二套管16之內側面流動，直到流體到達第二護套16之末端，靠近配件42。由於第二護套16之末端通常位於裸露區域（位天然氣錶或天然氣器具處），故洩漏能被個人（例如，通過氣味）所檢測到。
儘管已經顯示與描述了各種實施例，但是在不脫離本發明的精神和範圍的情況下，可以對其進行各種修改和替換。據此，應可理解本發明已經通過說明而非限制的方式描述。
