Description

一种具有耐正负压水封保护功能的密封装置 技术领域
本发明涉及下水管线水封保护技术领域，具体为一种排水管线用耐正负压密封装置。
背景技术
下水管线是建筑物排放污废水的管道也是城市重要的配套公共设施，为了防止下水管线内的污水及有毒有害气体返溢，通常在下水管线内设置防臭装置，下水管线防臭装置通常采用水封结构，仅依靠水封实现对使用空间与下水管线间的隔离，实现防臭和防有害气体返溢的功能。
由于下水管线中的压力会随着管线中的排水工况的变化而产生变化，当下水管线中形成负压时，负压会将水封中的水吸入下水管线中，导致水封破坏，使下水管线与使用空间连通，有害气体会从下水管线进入使用空间内，破坏室内环境，还影响人的身体健康。
发明内容
本发明就是针对上述问题，提供一种能避免负压破坏水封的排水管线用耐正负压密封装置。
为了实现本发明的上述目的，本发明采用如下技术方案，本发明包括套体，套体下端转动连接有启闭阀板，其特征在于：所述套体侧方设置有负压阀机构，所述负压阀机构包括槽体和多功能罩，槽体为斜面结构，槽体朝向套体内侧斜面上设置有压力传导膜，槽体内设置有与压力传导膜对应的压力传导体，压力传导体的推杆穿过与槽体配合连接的多功能罩，所述推杆通过锁定机构与所述启闭阀板相配合；所述的多功能罩上设置有连通下水管线的气压孔。
作为本发明的一种优选方案，所述槽体开口的表面倾斜设置于套体内，槽体开口的表面上端位于套体的上端口边缘处，槽体开口的表面下端位于套体下端口的中部；套体的上端口为进水口，槽体开口的表面下端和套体下端口围成的区域为下水口。
进一步的，所述套体的下端面设置有与启闭阀板上表面配合的密封环。
进一步的，所述槽体底部及多功能罩上和启闭阀板之间设置有斥力磁芯组和吸力磁芯组，所述启闭阀板转动至开启位置时，斥力磁芯组接近并产生排斥力，吸力磁芯组远离；所述启闭阀板转动至关闭位置时，斥力磁芯组远离，吸力磁芯组接近并产生吸引力。
更进一步的，所述启闭阀板两侧通过转轴与套体相连，所述吸力磁芯组设置于转轴靠近下水口的一侧；所述斥力磁芯组设置于转轴远离下水口的一侧。
作为本发明的另一种优选方案，所述的槽体开口处且面向套体内侧面位置设置有承压板，承压板和压力传导膜之间设置有连通套体内部空间的间隙。
作为本发明的第三种优选方案，所述压力传导膜和压力传导体之间设置有相互排斥的磁体。
进一步的，所述压力传导体上设置有磁块，所述压力传导膜上分散设置有磁力点； 所述磁力点和磁块的磁力相互排斥。
作为本发明的第四种优选方案，所述锁定机构包括竖向移动杆，所述竖向移动杆上端和压力传导体的推杆通过斜面配合；所述启闭阀板的端部设置有锁块，锁块和竖向移动杆通过弧形面配合。
本发明的有益效果：1、本发明当下水管线中产生负压时，压力传导膜受到两侧气压差作用力发生弹性变形，使压力传导膜向着压力传导体方向变形而位移，缩小了压力传导膜上磁力点与压力传导体上的磁块距离，增加了彼此间的相互斥力，由此推动压力传导体在槽体内产生位移，压力传导体的推杆作用于锁定机构，使锁定机构对启闭阀板进行锁定，启闭阀板不会被下水管线中的负压开启，与下水管线连接的水封也就不会发生破坏，从而避免了下水管线中的有害气体进入室内。
2、本发明的压力传导膜被承压板保护，避免下水时，水流对负压阀机构造成影响，也减小了水流动能对压力传导膜的作用力。
3、本发明的槽体开口的表面倾斜设置于套体内，使负压阀机构整体倾斜设置于套体内，增大了套体内部的水流空间，提高了排水能力。
4、本发明通过在压力传导膜上设置磁力点，并且磁力点和磁块的磁力相互排斥，能提高压力传导体的灵敏度，在负压很小时，压力传导体也能发生位移，保证锁定机构能将启闭阀板锁定，有效保护下水管线中的水封；同时，分散设置的磁力点不会影响压力传导膜的柔软性，保证压力传导膜能受负压影响产生变形，从而对压力传导体产生压迫动作。
5、本发明的锁定机构结构紧凑、合理，在狭小空间内有效传导运动，保证启闭阀板在下水管线内负压时不会开启，同时受到水流压力时，水流压力能克服锁定机构的阻力，开启启闭阀板，使排水顺畅进行。

具体实施方式
本发明包括套体1，套体1下端转动连接有启闭阀板15，其特征在于：所述套体1侧方设置有负压阀机构27，所述负压阀机构27包括槽体2和多功能罩29，槽体2为斜面7结构，槽体2朝向套体1内侧斜面7上设置有压力传导膜20，槽体2内设置有与压力传导膜20对应的压力传导体3，压力传导体3的推杆6穿过与槽体2配合连接的多功能罩29，所述推杆6通过锁定机构28与所述启闭阀板15相配合；所述的多功能罩29上设置有连通下水管线的气压孔4。
作为本发明的一种优选方案，所述槽体2开口的表面倾斜设置于套体1内，槽体2开口的表面上端位于套体1的上端口边缘处，槽体2开口的表面下端位于套体1下端口的中部； 套体1的上端口为进水口21，槽体2开口的表面下端和套体1下端口围成的区域为下水口16。
进一步的，所述套体1的下端面设置有与启闭阀板上表面配合的密封环14。
进一步的，所述槽体2底部及多功能罩29上和启闭阀板15之间设置有斥力磁芯组11和吸力磁芯组13，所述启闭阀板15转动至开启位置时，斥力磁芯组11接近并产生排斥力，吸力磁芯组13远离；所述启闭阀板15转动至关闭位置时，斥力磁芯组11远离，吸力磁芯组13接近并产生吸引力。
更进一步的，所述启闭阀板15两侧通过转轴12与套体1相连，所述吸力磁芯组13设置于转轴12靠近下水口16的一侧；所述斥力磁芯组11设置于转轴12远离下水口16的一侧。
作为本发明的另一种优选方案，所述的槽体2开口处且面向套体1内侧面位置设置有承压板18，承压板18和压力传导膜20之间设置有连通套体1内部空间的间隙17。
作为本发明的第三种优选方案，所述压力传导膜20和压力传导体3之间设置有相互排斥的磁体。
进一步的，所述压力传导体3上设置有磁块5，所述压力传导膜20上分散设置有磁力点19；所述磁力点19和磁块5的磁力相互排斥。
作为本发明的第四种优选方案，所述锁定机构28包括竖向移动杆8，所述竖向移动杆8上端和压力传导体3的推杆6通过斜面7配合；所述启闭阀板15的端部设置有锁块10，锁块10和竖向移动杆8通过弧形面9配合。
所述多功能罩上29设置有支撑臂22，支撑臂22上设置有竖向导槽23，所述竖向移动杆8两侧设置有与竖向导槽23配合的导向块。
所述启闭阀板15包括与下水口16形状对应的主体26，主体26一侧设置有杠杆24，杠杆24两侧设置有转轴12；所述套体1外设置有支撑杆25，支撑杆25下端与杠杆24的转轴12相配合。
所述锁块10设置于杠杆24的端部。
如图1所示，本发明使用时，套体1即可与下水管线直接相连使用，也可通过水封机构与下水管线相连，当排水管线中为负压时，槽体2内部与排水管线连通，槽体2内也形成负压，由于压力传导膜20和承压板18之间设置有间隙17，间隙17与下水管线外的室内空间连通，在大气压的作用下，压力传导膜20受压变形，负压较大时，压力传导膜20与压力传导体3接触，压迫压力传导膜20在槽体2内移动；负压较小时，压力传导膜20的磁力点19和磁块5在有一定距离的情况下，依然可以产生对压力传导体3的压力，压力传导体3在压力传导膜20的作用下在槽体2内移动，压力传导体3的推杆6斜向下移动，压力传导体3与竖向移动杆8的斜面7配合，竖向移动杆8两侧的导向块在竖向导槽23内滑动，使竖向移动杆8只能向下移动，竖向移动杆8下端与启闭阀板15端部的锁块10相接触，并给锁块10一个顺时针的压力；同时，启闭阀板15的吸力磁芯组13此时处于接近状态，也为启闭阀板15提供一个顺时针的力，从而使启闭阀板15保持关闭状态，大气压不能从下水口16进入排水管线，水封也就得以被保护。
当需要排水时，水流从套体1上端进水口21进入，承压板18能阻挡水流冲击压力传导膜20，随着水流下降，冲击启闭阀板15的主体26，由于水流压力远大于吸力磁芯组13形成的启闭阀板15闭合力，同时，竖向移动杆8和锁块10之间通过弧形面9配合，使启闭阀板15能顺畅的绕转轴12旋转并开启，不会发生卡阻；由于负压阀机构27倾斜设置，保证套体1内部 排水空间足够大，能快速将水排出；排水结束后，启闭阀板15和负压阀机构27之间的斥力磁芯组11产生排斥力，保证启闭阀板15复位到关闭下水口16的状态。
可以理解的是，以上关于本发明的具体描述，仅用于说明本发明而并非受限于本发明实施例所描述的技术方案，本领域的普通技术人员应当理解，仍然可以对本发明进行修改或等同替换，以达到相同的技术效果；只要满足使用需要，都在本发明的保护范围之内。
