Description

一种全程免维护应用的曲弹矢量结构管道*** 技术领域  Curved bullet vector structure pipeline system for whole maintenance-free application
本发明属于传输管道技术领域， 具体涉及一种全程免维护应用的曲弹矢 量结构管道***。 背景技术  The invention belongs to the technical field of transmission pipelines, and particularly relates to a curved-bullet structure pipeline system for maintenance-free applications. Background technique
长期以来的实践研究表明， 各类给水管道***在正常使用条件下所遭受 的破坏主要来自两个方面：  Long-term practice studies have shown that the damage suffered by various types of water supply pipeline systems under normal conditions of use mainly comes from two aspects:
1 )结构变形应力破坏性， 如： 管道***材料的热胀冷缩运动、 地震和输 送环境、 介质的温度、 压力变化产生的变形应力造成管道***结构的破坏。  1) Structural deformation stress destructiveness, such as: thermal expansion and contraction movement of pipeline system materials, earthquake and transmission environment, medium temperature, and deformation stress caused by pressure changes cause damage to the piping system structure.
2 )材料腐蚀应力破坏性， 如： 电化腐蚀、 化学腐蚀及输送环境、 介质的 腐蚀应力造成管道材料结构的破坏。  2) Material corrosion stress destructive, such as: galvanic corrosion, chemical corrosion and transport environment, the corrosion stress of the medium causes damage to the material structure of the pipeline.
随着近代新材料技术的突飞猛进， 在管道***的耐材料腐蚀应力破坏性 方面的问题已基本得到了有效解决， 譬如： 以有机高分子材料， 如聚乙烯 PE ( polyethylene, PE ), 聚丙烯 （ Polypropylene, PP )、 丙烯腈 -苯乙烯-丁二烯共 聚物 （Acrylonitrile Butadiene Styrene, ABS ) 等制造的管道***在一般应用条 件和环境中具有很好的耐化学腐蚀性和环境腐蚀性， 并且无电化腐蚀。 但是 以塑料为主体材料的管道***缺乏结构承载性， 不具备刚性， 因此应用范围 受到了很大程度的限制， 无法用于管道***的明装， 尤其是在现代髙层、 超 高层建筑体中的干管、 立管和明装分支管道。 而金属管道***则具备了金属 材料的结构刚性， 因此具备结构刚性的金属衬塑复合管道***便应运而生， 既有金属管道***的结构刚性， 又有塑料管道***的耐腐蚀性优势， 从而得 到了广泛性应用。  With the rapid advancement of modern new material technology, the problem of resistance to material corrosion stress in pipeline systems has been basically solved, for example: organic polymer materials such as polyethylene PE (polyethylene, PE), polypropylene ( Pipe systems manufactured by Polypropylene, PP), Acrylonitrile Butadiene Styrene (ABS), etc. have good chemical and environmental corrosion resistance under normal application conditions and environments, and Electrochemical corrosion. However, the pipe system with plastic as the main material lacks structural load capacity and does not have rigidity, so the application range is limited to a large extent, and it cannot be used for the installation of the pipe system, especially in modern concrete floors and super high-rise buildings. Dry pipes, risers and wall mounted branches. The metal pipe system has the structural rigidity of the metal material, so the metal-lined plastic composite pipe system with structural rigidity comes into being, which has the structural rigidity of the metal pipe system and the corrosion resistance of the plastic pipe system. Got a wide range of applications.
但是， 具有结构刚性的管 ¾***， 包括金属管道***和金属衬塑复合管 道***， 长期以来所面临的 "结构变形应力破坏性" 问题却一直没有得到有 效解决。 众所周知， 热胀冷缩是任何材料的基本属性， 由于管道材料的热胀 冷缩， 导致管道沿轴向位移的变化和在连接转弯处的管道结构变形； 建筑体 晃动、 地震等原因， 导致管道***沿径向的结构变形； 而所有这些问题都是 造成管道***结构破坏的根本性原因， 无法保障管道***长期安全运行。 管 道破裂、 连接处渗漏、 脱管已成为管道***运行的普遍事故现象， 造成了社 会资源的巨大浪费。 However, the structural rigidity of the pipe system, including the metal pipe system and the metal-lined plastic composite pipe system, has long been faced with the problem of "structural deformation stress destructiveness" has not been effectively solved. As we all know, thermal expansion and contraction is the basic property of any material. Due to the thermal expansion and contraction of the pipe material, the deformation of the pipe along the axial direction and the deformation of the pipe structure at the connection turn; the sway of the building body, earthquakes, etc., lead to the pipeline The structure of the system is deformed in the radial direction; and all these problems are The fundamental cause of the structural damage of the pipeline system cannot guarantee the long-term safe operation of the pipeline system. Pipe rupture, joint leakage, and pipe detachment have become common accidents in the operation of pipeline systems, resulting in huge waste of social resources.
传统管道***的解决方法是在管道直线段上， 按一定的长度距离设置伸 缩补偿段， 给予管道热胀冷缩变形的自由行程， 用以释放所产生的变形应力， 防止应力积累造成对管道结构破坏； 或釆取管道自然补偿方式， 如自由臂膨 胀 L弯补偿方法、 自由臂 U型弯补偿方法、 自由臂 Z字形折角弯补偿方法。  The solution to the traditional pipeline system is to set the telescopic compensation section on a straight section of the pipeline at a certain length distance, giving the pipeline a free travel of thermal expansion and contraction deformation, to release the generated deformation stress, and to prevent stress accumulation from causing the pipeline structure. Destruction; or draw the natural compensation method of the pipeline, such as the free-arm expansion L-bend compensation method, the free-arm U-bend compensation method, and the free-arm Z-shaped corner bend compensation method.
但是上述伸缩补偿方式无法从根本上解决热胀冷缩运动对管道***结构 的破坏性问题， 如在局部结构段上， 不仅是来自于热胀冷缩导致的局部变形 应力积累的破坏， 同时包括管道沿径向变形所产生的应力破坏， 尤其是可能 引发管道***的各个连接处产生渗漏或爆管。 发明内容  However, the above-mentioned telescopic compensation method cannot fundamentally solve the destructive problem of the thermal expansion and contraction motion on the piping system structure, such as the local structural section, not only the damage caused by the local deformation stress accumulation caused by thermal expansion and contraction, but also includes The stress damage caused by the radial deformation of the pipe, in particular, may cause leakage or bursting at various joints of the pipe system.

管道***是通过管材与管件的有效连接构成。 当管道***在输送介质温 度或环境温度发生变化时， 管道材料的热胀冷缩会沿管道轴向运动， 产生的 管道结构变形应力会传导至管材与管件的连接处， 而管道***的连接处本身 就是结构的薄弱点， 要么在此予以约束、 要么予以释放， 否则就会造成管道 ***连接处的彻底破坏， 导致连接处渗漏， 甚至爆管的运行质量事故。 同样， 在高层、 超高层和钢结构建筑体中， 由于地震、 自然结构晃动等原因会导致 管道沿径向的结构变形。  The piping system consists of an effective connection of the pipe to the pipe. When the pipeline system changes in the temperature of the conveying medium or the ambient temperature, the thermal expansion and contraction of the pipe material will move along the axial direction of the pipe, and the deformation stress of the pipe structure will be transmitted to the joint between the pipe and the pipe, and the connection of the pipe system. It is itself a weak point of the structure, either to be restrained or released here, otherwise it will cause complete damage to the connection of the piping system, resulting in leakage at the joint, and even the quality of the explosion. Similarly, in high-rise, super-high-rise and steel structures, structural deformation of the pipe in the radial direction may occur due to earthquakes, natural structural swaying, and the like.
本发明的基本设计理论是：釆用专项结构设计的弹性管道连接件与金属复 合管道的内管进行热熔连接， 形成一个在管道连接处的曲线弹性矢量结构区 段， 依靠各个连接处的曲弹矢量结构的有效变形来消除管道结构变形应力。 这样以来， 既保障了管道***的连接， 又全程解决了刚性管道***结构变形 应力所产生的破坏性， 管道***运行结构安全性从根本上得到了保障。  The basic design theory of the present invention is: the elastic pipe joint member designed with the special structure is thermally welded to the inner pipe of the metal composite pipe to form a curved elastic vector structure segment at the pipe joint, relying on the curvature of each joint. The effective deformation of the spring vector structure eliminates the deformation stress of the pipe structure. In this way, the connection of the pipeline system is guaranteed, and the destructiveness caused by the structural deformation stress of the rigid pipeline system is solved in the whole process, and the safety of the pipeline system operation structure is fundamentally guaranteed.

In order to facilitate the hot melt connection between the main pipe member 1 and the connecting pipe member 2. The connecting pipe 2 comprises a pipe body 6, and an elongated section 7 provided at least one end of the pipe body 6 and integral with the pipe body 6, and a connecting section of the lengthening section 7 inserted into the body pipe member 1 to connect the body pipe member 1 with the connecting pipe member 2. The length of the elongated section 7 is greater than or equal to the expansion elongation of the connecting section of the main tubular member 1 inserted into the elongated section 7 under the condition of maximum use temperature difference, which provides sufficient accommodation space for the thermal expansion of the main tubular member 1; the inner diameter of the elongated section 7 is equal to The outer diameter of the main tubular member 1 and the wall thickness of the elongated section 7 are equal to the wall thickness of the tubular body 6. The connection between the inside of the pipe body 6 and the extension section 7 is chamfered. When the main pipe member 1 and the connecting pipe member 2 are thermally fused, the ring-shaped welding is performed at the chamfering portion to make up for the axial hot-melt socket connection. "Leak or solder" to form a double weld quality and strength guarantee.

此外， 管体 6的外部、 内部表面的中部分别设置有外部加厚段 8和内部 加厚段 9; 外部加厚段 8的长度大于内部加厚段 9， 内部加厚段 9位于外部加 厚段 8的中部， 管体 6中部加厚段处管壁的最大厚度不小于管体 6壁厚与主 体管件 1的内管 5壁厚之和， 以保证管件整体壁厚是均匀的， 防止出现薄弱 段， 导致变形应力集中造成管件折弯甚至断裂； 在外部加厚段 8与管体 6外 表面的连接处设置有倒角，该倒角优选为 45°， 可以进一步防止管体在承受轴 向和径向弹性变形时的变形应力集中。  In addition, the outer portion of the tubular body 6 and the central portion of the inner surface are respectively provided with an outer thickened section 8 and an inner thickened section 9; the outer thickened section 8 has a length greater than the inner thickened section 9, and the inner thickened section 9 is located outside thickened. In the middle of the section 8, the maximum thickness of the pipe wall at the thickened section of the middle portion of the pipe body 6 is not less than the sum of the wall thickness of the pipe body 6 and the wall thickness of the inner pipe 5 of the main pipe member 1, so as to ensure that the overall wall thickness of the pipe member is uniform and prevent occurrence. The weak section causes the deformation stress to concentrate and cause the pipe to bend or even break; the joint between the outer thickened section 8 and the outer surface of the pipe body 6 is provided with a chamfer, which is preferably 45°, which can further prevent the pipe body from bearing the shaft The deformation stress concentrates when elastically deformed in the radial direction.
参照图 4所示， 为主体管件 1与连接管件 2的连接结构示意图， 本实施 例中， 连接管件 2选用直线型两通式连接管件， 在进行主体管件 1与连接管 件 2的热熔承插连接时， 将主体管件 1从端口处去掉外管 4， 外管 4去掉的 长度等于连接管件 2所要求的承插深度， 优选地， 将主体管件 1***连接管 件 2的长度设置为小于连接管件 2的端口距离其邻近的内部加厚段 9边缘的 距离， 即图 4中所示的 >l2。 这样， 主体管件 1的内管 5***连接管件 2之 后， 内管 5的端口与内部加厚段 9之间即形成一个环形凹槽， 如图 5中所示， 环形四槽内部可以容置主体管件 1与连接管件 2进行热熔承插连接时熔融物 堆积在管体内表面， 堵塞管道， 并且可以确保在任何温度变化和矢量结构变 形条件下， 将内管 5的轴向膨胀位移段和径向结构变形的外露段永远置于曲 弹矢量结构体保护中， 从而完善了金属衬塑复合管道***结构， 安全保障无 懈可击。 Referring to FIG. 4, it is a schematic diagram of the connection structure of the main pipe member 1 and the connecting pipe member 2. In the present embodiment, the connecting pipe member 2 is a linear type two-way connecting pipe member, and the hot-melt socket of the main pipe member 1 and the connecting pipe member 2 is performed. When connecting, the main pipe member 1 is removed from the port, and the outer pipe 4 is removed by a length equal to the required insertion depth of the connecting pipe member 2. Preferably, the length of the main pipe member 1 inserted into the connecting pipe member 2 is set to be smaller than the connecting pipe member. The distance of the port of 2 from the edge of its adjacent inner thickened section 9, i.e., >l 2 as shown in FIG. Thus, after the inner tube 5 of the main tube 1 is inserted into the connecting tube 2, an annular groove is formed between the port of the inner tube 5 and the inner thickening portion 9, as shown in Fig. 5, the inside of the annular four-slot can accommodate the main body. When the pipe member 1 is connected to the connecting pipe member 2 by hot-melt socket connection, the molten material accumulates on the inner surface of the pipe body, blocks the pipe, and can ensure the axial expansion and displacement of the inner pipe 5 under any temperature change and vector structural deformation conditions. The exposed section of the structural deformation is always placed in the protection of the curved spring vector structure, thus perfecting the structure of the metal-lined plastic composite pipe system, and the safety guarantee is impeccable.
此外， 在连接管件 2的至少一端的外部设置有刻度标记 10, 用来标识主体 管件 1的内管 5***连接管件 2的深度， 在热熔承插连接时， 只需依照刻度标记 10对主体管件 1端口处的外管 4进行适当长度的去除， 便于施工人员施工， 提 高工作效率。  In addition, a tick mark 10 is provided on the outside of at least one end of the connecting pipe member 2 for identifying the depth of the inner pipe 5 of the main pipe member 1 inserted into the connecting pipe member 2. When the hot-melt socket is connected, it is only necessary to follow the scale mark 10 to the main body. The outer tube 4 at the port of the pipe member is removed by an appropriate length to facilitate construction of the construction personnel and improve work efficiency.
在主体管件 1与连接管件 2热熔承插连接时， 管体 6与加长段 7连接处 的倒角位置， 形成环向堆积熔接， 如图 5所示， 一般而言， 轴向热熔承插连 接极易形成熔接缝隙或熔合面不足， 这是人工操作所无法避免的， 通常称之 为 "漏焊或虛焊"， 熔接质量无法得到有效保障， 造成***连接事故隐患。 环向堆积熔接可以将此 "漏焊或虛焊" 全部消除， 并形成双重熔接质量 和强度保障。 这是根据金属衬塑复合管道***曲弹矢量结构特征， 利用有机 高分子材料在熔融状态下的流体力学性能，创造性设计的环向堆积熔接结构。 让轴向承插熔接所产生的过盈材料流体， 在端口部形成环向堆积熔接段， 将 轴向承插熔接的缝隙和漏点悉数填充， 保障熔接质量， 并在结构安全与连接 强度方面给予了轴向承插熔接与环向堆积熔接的双重有效保障， 籍以保障并 提高曲弹矢量结构区段的安全可靠性。 When the main pipe member 1 is connected to the connecting pipe member 2 by hot-melt socket connection, the chamfered position of the joint between the pipe body 6 and the lengthening section 7 forms a circumferential direction welding, as shown in FIG. 5, generally, the axial hot-melt bearing The plug connection is easy to form a weld gap or the weld surface is insufficient. This is unavoidable by manual operation. It is usually called "leak weld or virtual weld", and the weld quality cannot be effectively guaranteed, which causes a hidden danger of the system connection accident. Circumferentially deposited welds can eliminate this "leak or weld" and form a double weld quality and strength guarantee. This is based on the structural characteristics of the curved structure of the metal-lined plastic composite pipe system, using the hydrodynamic properties of the organic polymer material in the molten state, and the creatively designed circumferentially stacked welded structure. The interference material fluid generated by the axial socket welding is formed into a circumferentially-distributed welding section at the port portion, and the gaps and the leakage points of the axial socket welding are filled in a complete manner to ensure the welding quality, and in terms of structural safety and connection strength. The double effective protection of the axial socket welding and the circumferential stack welding is given, so as to ensure and improve the safety and reliability of the curved spring vector structure section.
