Abstract
本发明涉及一种用于建筑物排水***中的压力释放装置(1),包括一个连接在***上的壳体(3),一个柔性容器(10)固定在所述装置上所述柔性容器(10)在排水***的空气瞬时正压力时是可操作的。其中所述壳体(3)和所述柔性容器(10)容纳在一个外壳(2)中。
Description
技术领域
本发明涉及一种空气正压力减弱装置,用于释放排水或污水处理***中的瞬时正压力。
背景技术
在这样的排水***中,尤其是在多于三层的建筑物中的排水***中,需要使用进气阀用来防止污浊空气的释放,以允许空气在排水管道和管道组中处于减压(负压)的条件下。在专利文献,例如GB2,014,697,EP0,084,303,EP0,278,746或EP1,026,329中公开了这样的阀。
然而,这些阀的使用防止了排水***中出现的空气瞬时正压力逃逸到大气中,导致排水***内的减压性能减弱。
专利文件EP0,172,966和EP0,661,483公开了下水道释放阀,其可响应由于在垂直的排水***内的下水和排水的回流而引起的过压而自动地打开。
然而,根据这些实施方案,这些空气过压通过将空气从下水道***排到大气中来释放和减弱。
这样的空气瞬时正压力应该在上述***中暂时得以减弱,而不是将污浊空气从该***中排到周围大气中。
发明内容
本发明提供了一种用于排水***中的压力释放装置,该装置包括壳体,柔性容器安装在该壳体上,所述柔性容器在排水***中的空气瞬时正压力变化时是可操作的,所述壳体和柔性容器容纳在外壳中。
优选地,所述壳体具有入口和出口,所述入口连接在所述排水***上,所述出口连接在一个帽上,使得壳体密封。所述壳体由刚性材料制成,以确保整个单元有足够的密封。所述壳体是一个连续的单元,所述柔性容器固定在所述连续单元上。在柔性容器覆盖壳体的地方,用于通风的装置允许空气从排水***自由地出入容器的内周边。用于壳体的合适的材料例如可以是PVC。
所述柔性容器容纳在外壳中,并且通过一个“O”型环和其它的连接在一个合适密封件上的弹性体紧固件,例如丁基橡胶和溶剂的未固化的膏剂,来密封壳体的入口和出口。所述“O”型环将柔性容器压在丁基橡胶膏剂的入口表面或出口表面上实现完全的密封。用于柔性容器的合适的材料例如是0.2mm厚度的丁基橡胶。
一个外壳包围在柔性容器周围,该外壳在底部具有用于向大气通风的装置。所述外壳可由例如PVC的刚性材料来制成。
在一个实施方案中,所述压力释放装置可以用作一个单一或“可独立应用”的单元。在另一个实施方案中,所述压力释放装置的出口在需要额外的容量时可以连接到另一个压力释放装置的入口上。在又一个实施中,所述压力释放装置或多个装置可以与进气阀一起使用来增加排水***的整体性能。
根据本发明装置的特性和必要元件记载在所附的权利要求中。
附图说明
结合附图,本发明仅仅示例性的进行说明,附图中:
图1是穿过压力释放装置的截面图;
图2是穿过壳体的截面图;
图3是所述壳体的示意图;以及
图4是串联在一起的两个压力释放装置的截面图。
具体实施方式
在附图中,压力释放装置1包括配壳2,壳体3,柔性容器10和端帽16。图1示出已装配的压力释放装置。所述柔性容器10覆盖壳体的中心部分,并且利用一个“O”型环8被固定在壳体入口6和壳体出口4上。所述柔性容器10利用压缩一层密封胶(未示出)的“O”型环抵靠在壳体入口6和壳体出口4上而被密封起来。这允许柔性容器10可以没有任何泄漏地进行操作。
所述壳体3的入口6和出口4通过隔板12连接在一起,所述两块隔板12在与柔性容器10接触时在入口6和出口4之间留有开放空间。
一部分外壳2与壳体3配合和与柔性容器10配合。所述外壳具有多个用于通风的装置20,例如在底座表面22上所示出的,其允许柔性容器10与大气(压力)永久接触,同时防止柔性容器10被外部事件损坏。
压力释放装置1通过阶梯状连接件18与排水***相连。所述阶梯状连接件18允许至少两种不同尺寸的管子以固定方式连接在一起,并且可以由弹性材料制成。
在图2中可以看出壳体3包括四个不同的部分。上部14通过分隔部分或隔板12通向壳体出口4和壳体入口6中。隔板12在柔性容器10完全崩塌时允许气流连续通过压力释放装置。
图3是一个没有上部14的壳体3的示意图。可以看出分隔板12没有完全围绕壳体3的圆周延伸。在隔板12之间的间隙允许空气从排水***进入柔性容器10中并且在***正压力下膨胀,从而吸收瞬时压力波的能量。
图4示出串联在一起的两个压力释放装置1。所述两个装置通过阶梯状连接件18被连接在一起,阶梯状连接件18将上面的压力释放装置5的壳体入口6与下面的压力释放装置7的上部14相连。
在两个压力释放装置之间,或一个压力释放装置和排水***之间或一个压力释放装置和一个空气进入阀之间的连接是推入式配合连接。
地面排水***是根据BS5572:1978(用于卫生管道***的实践编码)而设计的。
本发明提供了一种简单而有效的压力释放装置,其可以进行式样改进以适合现有的排水***。
尽管仅仅说明和示出了本发明的一个具体实施方案,但是很明显可以对其进行各种变化和修改。因此所附的权利要求的目的是覆盖了落入权利要求保护范围内的所有变化和修改。
