Description
法兰
技术领域
[0001] 本实用新型涉及一种连接件领域，具体涉及一种法兰。
背景技术
[0002] 现有的接头法兰，一般都是同一种金属材料或塑料制成的，其生产成本高。在水泵应用领域内，接头法兰一般为塑料或铸铁制成，全塑料的，易滑牙或者裂掉；铸铁的生产效率低，需要加工、车床、应用特种胶水粘结，需要专业的技术人员加工，在螺合的时候由于塑料制品其自身的硬度等缺陷，从而容易损坏。
实用新型内容
[0003] 本实用新型的目的是为了提供一种硬度好，不易损坏的法兰接头。
[0004] 为了解决上述技术问题，本实用新型采用以下的措施：本实用新型提供了一种法兰，包括金属管道、配接于管道外周的纤维增强塑料法兰盘，所述金属管道内壁设有螺纹，所述法兰盘包括第一内座和第一外座，所述第一外座从所述第一内座的一端部径向向外延伸，所述第一外座外周设有多个安装凸耳，所述安装凸耳中间设有通孔。
[0005] 在某种改进的技术方案中，所述纤维增强塑料法兰盘为耐腐蚀的树脂材料，所述耐腐蚀的树脂材料包括乙烯酯基材料。
[0006] 为了使所述的金属管道与法兰盘能很好的粘结，所述的法兰盘通过环氧粘结剂配接于金属管道外侧。
[0007] 其中，所述第一外座的端面设有阶梯环形凹槽，所述环形凹槽以金属管道为中心呈同心圆分布。
[0008] 进一步的，所述阶梯环形凹槽为二级阶梯槽，其所形成的平面相互平行且等间隔分布。
[0009] 进一步的，所述环形阶梯槽靠近金属管道的槽深大于外侧凹槽的槽深。
[0010] 本实用新型的有益效果是：
[0011] 将传统技术方案的塑料法兰改成其内部嵌配一金属管道的法兰，金属管道采用金属的特性，使所述的法兰在使用的过程当中不易损坏；法兰的外周使用塑料材质，降低了生产成本，而且使所述的法兰更加轻盈点，方便搬运。本法兰集安全、使用寿命长、密封性能好、适应高工作压力于一身；采用上述技术方案的法兰，提升了工人的装配效率，保证安装时不会胀开；采用内部嵌配一金属管道的法兰，降低了生产成本。
附图说明
[0012] 图1是本实用新型的法兰的剖面视图；
[0013] 图2是本实用新型的法兰的分解图；
[0014] 图3是本实用新型的法兰的整体结构示意图；
[0015] 图4是本实用新型的法兰的应用于水泵的安装结构示意图。[0016] 标号说明：
[0017] 第一内座I 第一外座2 安装凸耳3 金属管道4具体实施方式
[0018] 为详细说明本实用新型的技术内容、构造特征、所实现目的及效果，以下结合实施方式并配合附图详予说明。
[0019] 请参阅图1至图4，本法兰包括金属管道4、配接于管道外周的纤维增强塑料法兰盘，所述金属管道4内壁设有螺纹，所述法兰盘包括第一内座I和第一外座2，所述第一外座2从所述第一内座I的一端部径向向外延伸，所述第一外座2外周设有多个安装凸耳3,所述安装凸耳3中间设有通孔。法兰结构和金属管道4结构可以有任何适当的形状，例如两者中的任一个或两个可以有圆形、椭圆形或矩形的界面形状，金属管道4可以是圆形结构。该法兰为了能够安装在工件上，在所述第一外座2的外周设置安装凸耳3，所述安装凸耳3的中间设有通孔，安装凸耳3可以为任意的尺寸。
[0020] 在某种改进的技术方案中，所述纤维增强塑料法兰盘为耐腐蚀的树脂材料，所述耐腐蚀的树脂材料包括乙烯酯基材料。所述的树脂材料可以是半透明的或透明的，以允许人们能够看见形成的管状结构的内部，除树脂材料外，还包括纤维材料，例如，纤维材料可以是玻璃纤维、玻璃纤维织物、纺织的粗纱、纺布、缠绕的丝线，或用有机的细纱作为玻璃纤维的里外层，以便达到所需要的壁厚，对于某些应用，可以用石墨或碳纤维设置陶瓷纤维充实上面列举的纤维材料，以提高强度和耐火性。
[0021] 为了使所述的金属管道4与法兰盘能很好的粘结，所述的法兰盘通过环氧粘结剂配接于金属管道4外侧。粘结剂的选择方式有很多，在本技术方案中，仅以此种材料为例给予说明，在其他实施例中，可以使用其他的附属配件。
[0022] 所述第一外座2的端面设有阶梯环形凹槽，所述环形凹槽以金属管道4为中心呈同心圆分布，该阶梯环形凹槽能够根据实际需要设置不同的阶的阶梯，在本技术方案中，由于所述法兰端面的面积限制，因此设置二级阶梯槽为比较理想的设置方案，其所形成的平面相互平行且等间隔分布，所述环形阶梯槽靠近金属管道4的槽深大于外侧凹槽的槽深。通过设置凹槽，使所述的金属管道4外周与法兰盘之间、法兰盘的工作面之间粘结牢固程度大大增加，从而使法兰的整体密封性能得到提高，使其能适应高工作压力下使用。
[0023] 参阅图2，其为将以上所述的法兰应用于水泵的技术方案，所述的法兰在图中位于图2的左上角，所述水泵应用所述法兰，能使水泵的密封性更好。
[0024] 以上所述仅为本实用新型的实施例，并非因此限制本实用新型的专利范围，凡是利用本实用新型说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本实用新型的专利保护范围内。
