Description

压力容器
技术领域
本发明涉及压力容器,更详细地说,涉及提高密封性的压力容器。
背景技术
通常,为了储存氢气、氮气、天然气等各种气体,并根据需要排放已储存的气体,需要气体储存容器。特别是,气体在容器内的储存密度低,因此需要在高压下储存,在这种高压环境下使用压力容器是必不可少的。
例如,在包括燃料电池汽车或压缩天然气汽车的替代燃料气体汽车根据燃料气体的储存方法具有不同结构的储存系统,目前考虑到储存系统的单价、重量和简单性,压缩气体形式的储存方式正在受到瞩目。然而,由于气体状态的燃料为能量储存密度低,如果要确保更长的行驶距离,需要增加储存量或储存压力。尤其是,汽车的情况下,由于安装气体存储系统的空间有限,所以增加储罐的尺寸是有限的,因此安全储存高压的气体是储罐技术的核心。
然后,在燃气储罐中,如果是复合材料储罐,则外皮采用比强度和比刚性高的纤维增强复合材料加固,以应对压缩气体产生的内部压力,并且在内部插入保持气密性的内衬(Liner)。此时。燃料气体储罐根据内衬的材料分为不同的类型,插入诸如铝的金属材料内衬的储罐分为三类型,插入高密度聚合物内衬的储罐分为四类型。
详细地说,三类型的情况下,稳定性相对高,但是价格高、存在耐疲劳性差的缺点,相反地四类型储罐与三类型相比价格低廉、耐疲劳性优秀,但是存在氢气泄漏(leakage)及耐渗透性降低等的安全性问题。尤其是,为了安装外部阀门而适用的金属喷嘴和主体的塑料材料不同,因此凸台延伸部位的气密健全性很重要。
即,即使是利用塑料内衬制造压力容器的情况,喷嘴凸台也必须使用与内衬不同的金属材料或者非金属材料,因此存在在使用金属材料内衬时未出现的金属性或者非金属性喷嘴凸台和塑料内衬之间的粘结力降低的问题。
在此,为了解决如上所述的问题,在以往利用了用于粘接塑料内衬和金属相喷嘴凸台的塑料紧固件,但是这引起了在塑料内衬内部难以设置紧固件的其他问题。
作为另一方法,也使用了在喷嘴凸台设置槽,将喷嘴凸台插入成型在塑料内衬的方法,但是在实现完全粘接状态方面多少有些困难。
从而,处于迫切需要提高金属性或者非金属性喷嘴凸台和塑料内衬之间的粘接力以防止填充在内部的流体非正常流出的研究的实情。

另外,本发明提供一种压力容器,包括:上部内衬部,上部通过嵌件注塑结合于以上下方向延伸贯通孔的凸台部的外廓,以圆柱形从上部向下延伸并开口下部中心以在内部形成容纳流体的第一容纳空间,在所述上部内衬部形成有第一匹配部,所述第一匹配部包括外侧匹配凸起和上部辅助凸起,所述外侧匹配凸起从所述上部内衬部的下端边框侧半径方向外侧端向下延伸而且在内面沿着圆周方向以上下方向延伸形成垂直于激光照射方向的第一重叠结合面,上部辅助凸起从所述外侧匹配凸起的下端沿着圆周方向向半径方向外侧第一次一体地凸出,并且第二次向下延伸超过所述外侧匹配凸起下端的长度,而且在内面形成有第三重叠结合面;下部内衬部,上端边框结合于所述上部内衬部的下端边框,在所述下部内衬部形成有第二匹配部,所述第二匹配部包括内侧匹配凸起和下部辅助凸起,所述内侧匹配凸起从所述下部内衬部的上端边框侧半径方向内侧端向上延伸而且在外面第二重叠结合面沿着圆周方向以上下方向延伸形成以对于所述第一重叠结合面重叠配置在半径方向内侧来面接触,所述下部辅助凸起从所述下部内衬部的上部外面沿着圆周方向向半径方向外侧一体地凸出并且上端面接触于所述外侧匹配凸起的下端,所述第二匹配部材料与所述第一匹配部相同并且颜色亮度低于所述第一匹配部的颜色亮度,在与所述第三重叠结合面的半径方向内侧彼此相向的上部外面形成有第四重叠结合面,在所述下部内衬部的内部形成有连通于第一容纳空间的第二容纳空间。
(发明的效果)
通过上述的解决手段,本发明提供如下的效果:
第一,在彼此材料相同而且相比于黑色的第二匹配部亮度更高的白色或者透明色的第一匹配部和第二匹配部沿着半径方向重叠的情况下,若透过面接触于第一重叠结合面的第二重叠结合面的激光被吸收来进行加热,则可执行精确的焊接结合,因此可明显提高工作便利性。
第二,形成在上部内衬部的下端边框侧的外侧匹配凸起内面的第一重叠结合面和形成在下部内衬部的上端边框侧的内侧匹配凸起外面的第二重叠结合面沿着半径方向重叠并且面接触,而且与激光照射方向垂直形成,进而均匀地形成焊接结合区域,因此可明显提高密封性能。
第三,由于外侧匹配凸起及内侧匹配凸起沿着圆周方向以半径方向重叠结合,并且第一重叠结合面和第二重叠结合面以上下方向延伸,因此通过储存于压力容器内部的流体碰撞产生的压力产生反作用力,以彼此相向的方向加压并紧贴,从而可明显提高密封力。
第四,相互面接触并且沿着圆周方向以上下方向延伸形成的第一重叠结合面和第二重叠结合面与激光照射方向垂直形成,因此不要求调整用于焊接结合的激光的倾斜度的附加装置,可明显提高工作便利性及生产力。
第五,在外侧匹配凸起的下端外面倾斜的第一外侧倾斜面和外侧倾斜凸起的倾斜的内面、以及在内侧匹配凸起的上端内面倾斜的第一内侧倾斜面和内侧倾斜凸起的倾斜的外面面对面匹配,进而在焊接结合时将半径方向的流动最小化,因此均匀地形成结合区域,并且可明显提高制造精确度。
第六,若从外侧匹配凸起的下端向外侧第一次凸出并第二次向下延伸的上部辅助凸起内面的第三重叠结合面面接触并紧贴于下部内衬部的上部外面的第四重叠结合面来焊接结合,则形成双重的焊接结合区域,因此在因为组装错误而出现空隙时也可稳定地加强气密性能。

具体实施方式
以下,参照附图详细说明本发明的优选实施例的压力容器。
图1是示出本发明的一实施例的压力容器的剖面图;图2是示出在本发明的一实施例的压力容器中上部内衬部和下部内衬部之间的边界区域的剖面图。
如图1至图2所示,本发明的一实施例的压力容器400包括上部内衬部310及下部内衬部320。
在此,所述压力容器400作为为了在内部储存氧气、天然气、氮气、氢气等的各种流体而使用的容器,可使所述流体反复地选择性进入及排放。此时,所述流体以700bar的高压储存于所述压力容器400内部。
另一方面,优选为,所述凸台部10包括凸台延伸部,所述凸台延伸部配置成圆柱形并且在中心部沿着上下方向贯通形成贯通孔12。另外,优选为,所述凸台部10包括凸台凸缘部,所述凸台凸缘部在所述凸台延伸部的下部沿着圆周方向向半径方向外侧一体的扩张并且在半径方向内侧以上下方向延伸所述贯通孔12。
在此,所述凸台延伸部及所述凸台凸缘部相互形成一体,优选理解为所述凸台延伸部形成在所述凸台部10的上侧,所述凸台凸缘部形成在所述凸台部10的下侧。此时,所述凸台延伸部的外侧面可形成为从上端越来越向与下部的所述凸台凸缘部的边界区域沿着圆周方向向半径方向内侧凹陷并且凹陷成圆弧形状。
然后,所述凸台凸缘部的上面可形成为从与上部的所述凸台延伸部的边界区域越来越向下端沿着圆周方向向半径方向外侧扩张的形状。在此,包括所述凸台延伸部及所述凸台凸缘部的所述凸台部10可以是加工金属钢或者非金属铝等制造而成,材料不限于此。
另外,优选为,所述贯通孔12沿着上下方向贯通形成在所述凸台延伸部及所述凸台凸缘部的内部,并且上端向外侧开口,而下端连通于所述上部内衬部310内部的第一容纳空间310a。
再则,在所述贯通孔12中,在上侧内周面形成螺纹,以在流体进入所述压力容器400及向所述压力容器400的外部排放流体时与外部装置(未示出)螺纹紧固,进而防止流体泄漏。
另一方面,优选为,所述上部内衬部310配置成下部开口的容器型,形成有连通于所述贯通孔12的所述第一容纳空间310a,以在内部容纳流体。另外,优选为,所述上部内衬部310的上部通过沿着所述凸台凸缘部的下面嵌件注塑来密封结合。
然后,优选为,所述下部内衬部320配置成上部开口的容器型,形成有连通于所述第一容纳空间310a的第二容纳空间320a,以在内部容纳流体。另外,优选为,所述下部内衬部320的下部通过沿着凸台尾部210的上面嵌件注塑来密封结合。此时,所述凸台尾部210材料可与所述凸台部10的材料相同。当然,所述凸台尾部210的材料实际上可与所述凸台部10的相同,但是在各个材料之间的添加物可以有细微的差异,并且优选理解为这包括在本发明的权利范围内。
在此,所述上部内衬部310及所述下部内衬部320的材料可以是合成树脂材料,即与所述凸台部10及所述凸台尾部210不同的材料。此时,举例说明所述上部内衬部310的制造过程。在此,优选理解为,所述下部内衬部320的制造过程实际上与所述上部内衬部310的制造过程相同。例如,所述凸台部10插入于上部模具(未示出)和下部模具(未示出)之间,在所述上部模具(未示出)和所述下部模具(未示出)之间可形成与所述凸台部10连通的间隔空间(未示出)。接着,合成树脂注入于所述间隔空间(未示出)硬化,从而可嵌件注塑所述上部内衬部310。
然后,所述上部内衬部310及所述下部内衬部320可个别制造,并且彼此之间可通过激光焊接相互结合。此时,在所述上部内衬部310的下端边框和所述下部内衬部320的上端边框相互嵌入结合而重叠的状态下彼此之间可通过从半径方向外侧照射的激光相互熔融结合。
详细地说,参照图2,优选为,所述上部内衬部310的上部是通过嵌件注塑结合于以上下方向延伸所述贯通孔12的所述凸台部10的外廓。
然后,优选为,所述上部内衬部310以圆柱形从结合于所述凸台部10的上部向下延伸并且开口下部中心,以在内部形成容纳流体的所述第一容纳空间310a。此时,在所述上部内衬部310的半径方向内侧形成有所述第一容纳空间310a。
另外,优选为,在所述上部内衬部310中,在下端边框形成有第一匹配部311,所述第一匹配部311为沿着圆周方向以上下方向延伸形成垂直于激光照射方向K1的第一重叠结合面312a而成。
此时,所述激光照射方向K1是指对于所述上部内衬部310的下端及所述下部内衬部320上端之间的边界区域侧外面沿着圆周方向从半径方向外侧垂直照射激光的方向。
另一方面,优选为,所述下部内衬部320的上端边框插入结合于所述上部内衬部的下端边框之后通过激光焊接熔融结合。
在此,优选为,在所述下部内衬部320中,在上端边框形成第二匹配部321,所述第二匹配部321为沿着圆周方向以上下方向延伸形成垂直于激光照射方向K1的第二重叠结合面322a。
然后,优选为,所述第二重叠结合面322a以半径方向重叠于所述第一重叠结合面312a从而相互面对的面接触。此时,在本发明的一实施例中,将所述第二重叠结合面322a对于所述第一重叠结合面312a配置在半径方向内侧的情况作为一示例进行了示出及说明,但是不限于此。即,根据情况,所述第二重叠结合面对于所述第一重叠结合面也可配置在半径方向外侧。
另外,优选为,在所述下部内衬部320的内部形成有连通于第一容纳空间310a的所述第二容纳空间320a。再则,优选为,所述下部内衬部320的下部通过嵌件注塑结合于所述凸台尾部210的外廓。
另一方面,优选为,所述上部内衬部310及所述下部内衬部320和所述第一匹配部311及所述第二匹配部321彼此之间的材料相同。此时,最优选为,所述上部内衬部310及所述下部内衬部320的材料为含有聚酰胺(polyamide)的合成树脂材料。
另外,所述上部内衬部310及所述下部内衬部320与所述第一匹配部311及所述第二匹配部321彼此之间的材料实际上相同。当然,所述上部内衬部310及所述下部内衬部320与所述第一匹配部311及所述第二匹配部321在各个材料之间的添加物可以有细微的差异,并且优选理解为这包括在本发明的权利范围以内。
然后,优选为,所述第一重叠结合面312a对于所述第二重叠结合面322a配置在半径方向外侧,所述第一匹配部311的颜色亮度高于所述第二匹配部321的颜色亮度。
在此,最优选为,所述上部内衬部310全部颜色亮度高于所述下部内衬部320的颜色亮度。当然,根据情况,也可以是只有所述第一匹配部311一部分颜色亮度高于所述第二匹配部321的颜色亮度。
例如,所述第一匹配部311的颜色可以是白色,以使激光透过,所述第二匹配部321颜色可以是黑色,从而,若照射激光则所述第二匹配部321的外面吸收热而被加热熔融。或者,所述第一匹配部311的颜色也可以是透明色,而所述第二匹配部321的颜色也可以是黑色。
据此,若从半径方向外侧沿着圆周方向透射激光到达面接触于所述第一重叠结合面312a的所述第二重叠结合面322a,则可执行所述第一重叠结合面312a及所述第二重叠结合面322a之间的焊接结合。
从而,使用相同的材料而且颜色亮度高于黑色的所述第二匹配部321亮度的白色或者透明色的所述第一匹配部311和所述第二匹配部321沿着半径方向重叠。据此,若透射于面接触于所述第一重叠结合面312a的所述第二重叠结合面322a的激光被吸收而被加热,则精确地执行焊接结合,因此可明显提高工作便利性。
另一方面,参照图2,优选为,所述第一匹配部311包括外侧匹配凸起312,所述外侧匹配凸起312从所述上部内衬部310的下端边框侧半径方向外侧端向下延伸,而且在内面形成有所述第一重叠结合面312a。
另外,优选为,所述第二匹配部321包括内侧匹配凸起322,所述内侧匹配凸起322从所述下部内衬部320的上端边框侧半径方向内侧端向上延伸而且在外面形成面接触于所述第一重叠结合面312a的所述第二重叠结合面322a。
据此,所述外侧匹配凸起312和所述内侧匹配凸起322沿着圆周方向以半径方向相互重叠并且可嵌合。此时,所述第一重叠结合面312a及所述第二重叠结合面322a相互面接触,在与所述激光照射方向K1垂直对齐配置的状态下彼此之间通过激光熔融结合。
此时,现有技术的特征是通过激光熔融结合的结合面未与所述激光照射方向K1垂直设置而是倾斜形成,如此在焊接过程中根据结合面的厚度形成不均匀的熔接区域。
与此相反,本发明为形成在所述外侧匹配凸起312内面的所述第一重叠结合面312a和形成在所述内侧匹配凸起322外面的所述第二重叠结合面322a沿着半径方向重叠而面接触。另外,所述第一重叠结合面312a和所述第二重叠结合面322a与所述激光照射方向K1垂直形成。据此,相互面接触的所述第一重叠结合面312a和所述第二重叠结合面322a之间的焊接结合区域沿着上下方向均匀形成,因此可明显提高密封性。
另外,相互面接触并且沿着圆周方向以上下方向延伸形成的所述第一重叠结合面312a和所述第二重叠结合面322a与所述激光照射方向K1垂直形成。从而,不要求倾斜用于焊接结合的激光的附加装置,因此可明显提高工作便利性及生产力。
再则,所述外侧匹配凸起312及所述内侧匹配凸起322沿着圆周方向以半径方向重叠结合,并且所述第一重叠结合面312a和所述第二重叠结合面322a以上下方向延伸。从而,通过储存于所述压力容器400内部的流体碰撞产生压力进而产生的反作用力以相互面对的方向加压紧贴,从而可明显提高密封力。即,所述内侧匹配凸起322被流体的膨胀压力向半径方向外侧加压,而所述外侧匹配凸起312被反作用力向半径方向内侧加压。
另一方面,优选为,在所述外侧匹配凸起312的下端外面形成第一外侧倾斜面312b,所述第一外侧倾斜面312b越向端部就越向半径方向内侧倾斜而变得狭窄。再则,在所述内侧匹配凸起322的上端内面形成第一内侧倾斜面322b,所述第一内侧倾斜面322b越向端部就越向半径方向外侧倾斜而变得缩窄。
然后,优选为,所述第一匹配部311包括内侧倾斜凸起313,所述内侧倾斜凸起313从所述上部内衬部310的下端边框的半径方向内侧端向下延伸,而且外面越向端部就越向半径方向内侧倾斜而变得缩窄。
在此,优选为,所述内侧倾斜凸起313与所述第一重叠结合面312a的上端弯曲形成。即,所述内侧倾斜凸起313的倾斜的外面和所述第一重叠结合面312a之间的角度可设定为大于0°且小于90°。此时,优选为,所述外侧匹配凸起312向下延伸超过所述内侧倾斜凸起313下端部的长度。
然后,优选为,所述第二匹配部321包括外侧倾斜凸起323,所述外侧倾斜凸起323从所述下部内衬部320的上端边框的半径方向外侧端向上延伸,而且内面越向端部就越向半径方向外侧倾斜而变得狭窄。
在此,优选为,所述外侧倾斜凸起323与所述第二重叠结合面322a的下端弯曲形成。即,所述外侧倾斜凸起323的倾斜的内面和所述第二重叠结合面322a之间的角度可设定为大于0°且小于90°。此时,优选为,所述内侧匹配凸起322向上延伸超过所述外侧倾斜凸起323上端部的长度。
另外,优选为,所述内侧倾斜凸起313的倾斜的外面与所述第一内侧倾斜面322b相互面对面匹配,同时所述外侧倾斜凸起323的倾斜的内面与所述第一外侧倾斜面312b面对面匹配。此时,面对面匹配的剖面边界可形成“Z”字形状。即,优选为,在所述外侧匹配凸起312的下端外面越向端部就越向半径方向内侧倾斜而变得狭窄的所述第一外侧倾斜面312b嵌入结合所述外侧倾斜凸起323的倾斜的内面以实现面对面匹配。
与此同时,优选为,在所述内侧匹配凸起322的上端内面越向端部就越向半径方向外侧倾斜而变得狭窄的所述第一内侧倾斜面322b嵌入结合所述内侧倾斜凸起313的倾斜的外面以实现面对面匹配。据此,通过照射激光进行焊接结合时,将半径方向的流动最小化,因此均匀地形成结合区域,可明显提高制造精确度。
另一方面,图3是示出在本发明的一实施例的压力容器中上部内衬部和下部内衬部之间的边界区域的变形例的剖面图。在本变形例中,除了上部辅助凸起1314及下部辅助凸起1324以外的基本结构与上述的一实施例相同,因此省略相同结构的说明,对于相同结构使用相同的附图标记。
如图3所示,本发明的一实施例的变形例的压力容器1400包括上部内衬部1310及下部内衬部1320。此时,所述上部内衬部1310及所述下部内衬部1320的材料及颜色与上述的一实施例相同,因此省略详细说明。另外,优选理解为所述上部辅助凸起1314及所述下部辅助凸起1324的材料及颜色分别与所述上部内衬部1310及所述下部内衬部1320的材料及颜色相同。
在此,优选为,所述上部内衬部1310包括第一匹配部1311,所述第一匹配部1311包括外侧匹配凸起312。另外,优选为,所述下部内衬部1320包括第二匹配部1321,所述第二匹配部1321包括外侧倾斜凸起323。
详细地说,优选为,所述第一匹配部1311包括所述上部辅助凸起1314,所述上部辅助凸起1314从所述外侧匹配凸起312的下端侧外面沿着圆周方向向半径方向外侧第一次一体地凸出。此时,优选为,所述上部辅助凸起1314向下第二次延伸超过所述外侧匹配凸起312下端的长度。
在此,在所述上部辅助凸起1314的上部侧外面可形成有上部倾斜面1314b,所述上部倾斜面1314b沿着圆周方向越向下端就越向半径方向外侧倾斜扩张。再则,所述上部辅助凸起1314的下部侧外面从所述上部倾斜面1314b的下端沿着圆周方向以上下方向向下延伸成直线形状。
然后,优选为,在所述上部辅助凸起1314的内面中,面接触于所述下部内衬部1320的上部外面的第三重叠结合面1314a垂直于激光照射方向K2沿着圆周方向以上下方向延伸形成。
此时,优选为,所述第三重叠结合面1314a的上端与形成在所述外侧匹配凸起312下端的第一外侧倾斜面312b的半径方向外侧端弯曲形成。即,所述第三重叠结合面1314a和所述第一外侧倾斜面312b之间的角度可设定为大于0°且小于90°。优选为,在图3用K1、K2示出的激光照射方向彼此可水平设定,是在彼此之间以上下方向间隔的位置个别照射激光的方向。
另一方面,优选为,所述第二匹配部1321包括所述下部辅助凸起1324,所述下部辅助凸起1324从所述下部内衬部1320的上部外面沿着圆周方向向半径方向外侧一体的凸出。此时,优选为,所述下部辅助凸起1324的上面面接触于所述上部辅助凸起1314的下面。
在此,在所述下部辅助凸起1324的下部侧外面可形成下部倾斜面1324a,所述下部倾斜面1324a沿着圆周方向越向上端就越向半径方向外侧倾斜扩张。再则,所述下部辅助凸起1324的上部侧外面从所述下部倾斜面1324a的上端沿着圆周方向以上下方向向下延伸成直线形状。此时,所述上部辅助凸起1314的下部侧外面及所述下部辅助凸起1324的上部侧外面设定为彼此相对应的直径,进而可形成连续的外面轮廓。
然后,优选为,在与所述第三重叠结合面1314a的半径方向内侧彼此相向的所述下部内衬部1320的上部外面沿着圆周方向垂直于激光照射方向K2以上下方向延伸形成第四重叠结合面1323a。此时,优选为,所述第四重叠结合面1323a面接触并紧贴于所述第三重叠结合面1314a。
在此,优选为,所述第三重叠结合面1314a形成在所述上部辅助凸起1314的内面,所述第四重叠结合面1323a可形成在与所述第三重叠结合面1314a彼此相向的所述外侧倾斜凸起323的上端外面。然后,所述第四重叠结合面1323a的下端与所述下部辅助凸起1324的上面垂直地弯曲形成。
从而,从所述外侧匹配凸起312的下端第一次向外侧凸出并且第二次向下延伸的上部辅助凸起1314的下面和从所述下部内衬部1320的上部外面向外侧凸出的所述下部辅助凸起1324的上面面接触。
与此同时,所述上部辅助凸起1314内面的所述第三重叠结合面1314a面接触并紧贴于彼此相向的所述下部内衬部1320的上部外面的所述第四重叠结合面1323a来焊接结合。
据此,不仅是焊接结合区域形成在所述第一重叠结合面(图2的312a)及所述第二重叠结合面(图2的322a)之间,还双重的形成在所述第三重叠结合面1314a及所述第四重叠结合面1323a之间。
据此,在所述第一匹配部1311及所述第二匹配部1321嵌入结合时,因为组装错误导致所述外侧匹配凸起312和所述外侧倾斜凸起323之间出现空隙的情况下,也可加强气密性。
