    • A tubular structure (10) including an expanded fluoropolymer material having an outer surface (12), an inner surface (14), and a wall (16) therebetween. The wall (16) defines a channel (18). A hose assembly (100) includes a tubular inner liner (110) formed of the expanded fluorocarbon polymeric material having an outer surface (112), an inner surface (114), and a wall (116) therebetween defining a channel (118). The hose assembly (110) further includes at least one outer liner (121) disposed about the outer surface (112) of the tubular inner liner (110). A method of making a tubular structure (10) formed of the expanded fluoropolymer material includes the steps of extruding a fluoropolymer tubular structure (10) having an outer surface (12), an inner surface (14), and a wall (16) therebetween defining a channel (18) on an extruder having at least one barrel, at least one screw, at least one mandrel, and at least one die. The method further includes the steps of applying a vacuum to the outer surface (12) to prevent the tubular structure (10) from collapsing and polymerizing the tubular structure (10). A method for constructing a hose assembly (100) includes the steps of extruding a fluoropolymer tubular inner liner (110) and disposing at least one outer liner (121) about the tubular inner liner (110).
    • 包括具有外表面(12),内表面(14)和其间的壁(16)的膨胀的含氟聚合物材料的管状结构(10)。 壁(16)限定通道(18)。 软管组件(100)包括由膨胀的碳氟化合物聚合物材料形成的管状内衬(110),其具有外表面(112),内表面(114)和位于其间的壁(116),限定通道(118)。 软管组件(110)还包括围绕管状内衬(110)的外表面(112)设置的至少一个外衬垫(121)。 由膨胀的含氟聚合物材料制成的管状结构(10)的方法包括以下步骤:在其间挤出含有外表面(12),内表面(14)和壁(16)的含氟聚合物管状结构(10) 在具有至少一个筒的挤出机上限定通道(18),至少一个螺杆,至少一个心轴和至少一个模具。 该方法还包括对外表面(12)施加真空以防止管状结构(10)使管状结构(10)塌陷和聚合的步骤。 构造软管组件(100)的方法包括挤压含氟聚合物管状内衬(110)并且围绕管状内衬(110)设置至少一个外衬垫(121)的步骤。

    • A quick connect hose coupling assembly (10) for connecting a hose to an external device is disclosed. The assembly (10) includes a female coupling assembly (12) having an inner female tubular member (16). A housing member (14) is mounted thereon. The female member (16) includes a body portion (17) and a stem (20) adapted to be inserted into the inner channel (37) of a hose (38). The stem (20) includes an axial bore (21) adapted to convey a fluid therethrough. The stem (20) further includes a plurality of circumferential barbs (22). The stem (20) can also include an additional barb having a rotation resisting structure provided thereon to resist relative rotational movement between the stem (20) and a hose (38) into which the stem (20) is disposed. In a preferred embodiment of the invention, after the stem (20) is inserted into the end of the hose (38), a collar (40) of a plastic material is directly molded onto the portion of the hose (38) which is mounted over the stem (20), over a portion of the body (17) of the female member (18), and over a portion of the female housing member (14), thereby clamping the hose (38) to the stem (20), and affixing the collar (40) to the female member (18) and to the female housing member (14). Additionally, a novel detent clip (72) is inserted in apertures (64) provided in the housing member (14) to cooperate in engaging a circumferential flange provided on a male member (66), thereby retaining the male member (66) within the channel (18) of the female member (16).
    • 公开了一种用于将软管连接到外部装置的快速连接软管接头组件(10)。 组件(10)包括具有内阴管状构件(16)的阴联接组件(12)。 壳体构件(14)安装在其上。 阴构件(16)包括主体部分(17)和适于插入软管(38)的内部通道(37)中的杆(20)。 杆(20)包括适于输送流体的轴向孔(21)。 杆(20)还包括多个圆周倒钩(22)。 杆(20)还可以包括附加的倒钩,其具有设置在其上的旋转抵抗结构,以抵抗杆(20)和杆(20)设置在其中的软管(38)之间的相对旋转运动。 在本发明的优选实施例中,在杆(20)插入软管(38)的端部之后,将塑料材料的套环(40)直接模制到软管(38)的安装的部分上 在所述杆(20)上方超过所述阴构件(18)的主体(17)的一部分上方并且在所述阴壳体构件(14)的一部分上方,从而将所述软管(38)夹紧到所述杆(20) ,并将所述套环(40)固定到所述阴构件(18)和所述凹形壳体构件(14)。 此外,将新颖的止动夹(72)插入到设置在壳体构件(14)中的孔(64)中,以配合接合设置在阳构件(66)上的圆周凸缘,从而将阳构件(66)保持在 阴构件(16)的通道(18)。
