具体实施方式
图1为本申请实施例提供的一种应用于废气处理系统的阀门控制装置的结构示意图,参考图1,应用于废气处理系统的阀门控制装置包括气体输入端A1、控制模块10、第一阀门11、第二阀门12、执行模块13和控制阀门14;气体输入端A1接入控制空气,气体输入端A1与第一阀门11的第一输入选择端A2连接,第一阀门11的第一输出选择端U1与第二阀门12的第二输入选择端A3连接,第二阀门12的第二输出选择端U2与执行模块13的输入端连接,执行 模块13的输出端与控制阀门14连接,控制模块10分别与第一阀门11和第二阀门12电连接;控制模块10设置为接收到快速开启控制阀门指令时,控制第一阀门11处于工作状态、控制第二阀门12处于失效状态,以使气体输入端A1、第一阀门11、第二阀门12构成第一通路,所述控制空气经所述第一通路进入执行模块13中以开启控制阀门14。
控制空气是用于对应用于废气处理系统的阀门控制装置进行控制的压缩气体,常用的控制空气的压力值为6-8bar。工作状态或失效状态为第一阀门11或第二阀门12的两种不同工作状态。第一阀门11和第二阀门12内均包括多个路径,且第一阀门11或第二阀门12处于某一状态时,气体输入端A1仅与第一阀门11中一个路径连通,第一阀门11也仅与第二阀门12中一个路径连通,执行模块13也仅与第二阀门12的一个路径连通。控制模块10接收到快速开启控制阀门指令时,控制第一阀门11处于工作状态、控制第二阀门12处于失效状态,示例性的,此时第一阀门的第一路径与气体输入端A1连接,第一路径又与第二阀门12的第二路径连接,因此,控制空气从气体输入端A1输出后,经第一阀门11的第一路径、第二阀门12的第二路径输入执行模块13中,再经执行模块13输入控制阀门14中。可选的,执行模块13为气动执行器,气动执行器是用气压力驱动启闭或调节阀门的执行装置。当控制空气进入气动执行器后,气动执行器中的活塞压缩弹簧做功,活塞上的齿条或拉杆带动旋转轴上的齿轮或拨叉逆时针方向转动90度,控制阀门14即被打开。
本实施例提供的应用于废气处理系统的阀门控制装置可应用于废气处理系统中。在废气处理的过程中,如遇紧急情况,需将控制阀门快速打开。相较于控制空气经众多繁琐的设备才能进入执行模块中,本实施例的应用于废气处理系统的阀门控制装置在需快速开启控制阀门的情况下,控制空气经第一阀门、第二阀门进入执行模块中,以开启控制阀门,第一阀门和第二阀门结构简单、便于控制,进而可缩短开启控制阀门的时间,提升应用于废气处理系统的阀门控制装置的响应能力。同时第一阀门和第二阀门制造方便,成本较低,可降低 应用于废气处理系统的阀门控制装置的成本。
继续参考图1,可选的,第一阀门11包括第一端B1、第二端B2、第三端B3、第四端B4和第五端B5,第一端B1和第二端B2连通,第四端B4和第五端B5连通,第三端B3截止,第二阀门12包括第六端B6、第七端B7、第八端B8、第九端B9和第十端B10,第六端B6和第七端B7连通,第九端B9和第十端B10连通,第六端B6还与外部环境连通,第八端B8截止;
控制模块10设置为控制第一阀门11处于工作状态且第二阀门12处于失效状态时,控制第一端B1与气体输入端A1连接、第二端B2与第九端B9连接、第十端B10与执行模块13的输入端连接。
可选的,第一阀门11和第二阀门12均为电磁阀。第一阀门11得电时处于工作状态,失电时处于失效状态,第二阀门12得电时处于工作状态,失电时处于失效状态。控制模块10接收到快速开启控制阀门指令时,控制第一阀门11得电、第二阀门12失电。第一阀门11得电时,第一阀门11的第一端B1作为第一输入选择端A2与气体输入端A1连接,第二端B2作为第一输出选择端U1与第二阀门12连接,第九端B9作为第二输入选择端A3与第二端B2连接,第十端B10作为第二输出选择端U2与执行模块13的输入端连接。因此,控制模块10控制第一阀门11得电、第二阀门12失电时,控制空气经气体输入端A1、第一端B1、第二端B2、第九端B9、第十端B10进入执行模块13中以开启控制阀门14。
图2为本申请实施例提供的另一种应用于废气处理系统的阀门控制装置的结构示意图,参考图2,可选的,应用于废气处理系统的阀门控制装置还包括定位模块15,定位模块15的输入端与气体输入端A1连接,定位模块15的输出端与第一阀门11的第三输入选择端A4连接,定位模块15的控制端与控制模块10电连接;
控制模块10设置为接收到控制阀门开启程度调节指令时,控制定位模块15中流入的控制空气的体积,并控制第一阀门11处于失效状态、第二阀门12 处于失效状态,以使第一通路断开、气体输入端A1、定位模块15、第一阀门11、第二阀门12构成第二通路,以使控制空气经第二通路进入执行模块13以调节控制阀门14的开启程度。
定位模块15可以为阀门定位器,控制阀门开启程度调节指令可以为电流信号,每一电流值对应一开启程度,示例性的电流值4-20mA,对应开启角度为0-90°,其中4mA对应控制阀门14开启角度为0°,20mA对应控制阀门14开启角度为90°。控制模块10通过控制控制空气流入定位模块15中的体积来实现对控制阀门14开启角度的控制,即电流值与定位模块15中流入的控制空气的体积一一对应,控制空气的体积又与控制阀门14开启角度一一对应。第一阀门11处于失效状态、第二阀门12处于失效状态时,第一通路断开,即控制空气无法通过第一通路进入执行模块13中。此时,控制空气经气体输入端A1、定位模块15、第一阀门11、第二阀门12构成的第二通路进入执行模块13中,进而通过定位模块15实现对控制阀门14的开启程度的调节。
继续参考图2,可选的,控制模块10设置为控制第一阀门11处于失效状态、第二阀门12处于失效状态时,控制第三端B3与气体输入端A1连接、第四端B4与定位模块15的输出端连接、第五端B5与第九端B9连接、第十端B10与执行模块13的输入端连接。
控制模块10接收到控制阀门开启程度调节指令时,控制第一阀门11失电、第二阀门12失电。第一阀门11失电时,第一阀门11的第三端B3作为第一输入选择端A2与气体输入端A1连接,第四端B4作为第三输入选择端A4与定位模块15的输出端连接,第五端B5作为第一输出选择端U1与第二阀门12连接,第九端B9作为第二输入选择端A3与第五端B5连接,第十端B10作为第二输出选择端U2与执行模块13的输入端连接。因此,控制模块10控制第一阀门11得电、第二阀门12失电时,控制空气经第三端B3进入第一阀门11后,第三端B3在第一阀门11中截止,无法将气体继续向第二阀门13传输,因此控制空气无法直接经第一阀门11、第二阀门12传输至执行模块13中。控制空气 输入端A1、定位模块15、第四端B4、第五端B5、第九端B9、第十端B10进入执行模块13中,进而通过定位模块15实现对控制阀门14的开启程度的调节。
图3为本申请实施例提供的另一种应用于废气处理系统的阀门控制装置的结构示意图,参考图3,可选的,控制模块10还设置为接收到快速关闭控制阀门指令时,控制第一阀门11处于失效状态、第二阀门12处于工作状态,以使第一通路断开、第一阀门11、第二阀门12构成第三通路,并使执行模块13中的控制空气经第三通路排出,使控制阀门14关闭。
控制模块10在接收到快速关闭控制阀门指令时,控制第一阀门11和第二阀门12的状态,以使第一通路断开,控制空气无法通过第一阀门11和第二阀门12进入执行模块13中。执行模块13中残留的气体经第二阀门12排出至外部环境中,使得执行模块13中活塞被弹簧推动将气缸内控制空气排出,活塞上的齿条或拉杆带动旋转轴上的齿轮或拨叉顺时针方向转动,以关闭控制阀门14。
继续参考图3,可选的,控制模块10设置为控制第一阀门11处于失效状态且第二阀门12处于工作状态时,控制第三端B3与气体输入端A1连接、第五端B5与第八端B8连接、第七端B7与执行模块13的输入端连接。
控制模块10接收到快速关闭控制阀门指令时,控制第一阀门11失电、第二阀门12得电。第一阀门11失电时,第一阀门11的第三端B3作为第一输入选择端A2与气体输入端A1连接,第五端B5作为第一输出选择端U1与第二阀门12连接,第八端B8作为第二输入选择端A3与第五端B5连接,第七端B7作为第二输出选择端U2与执行模块13的输入端连接。因此,控制模块10控制第一阀门11失电、第二阀门12得电时,控制空气经第三端B3进入第一阀门11后,第三端B3在第一阀门11中截止,无法将气体继续向第二阀门13传输,因此控制空气无法直接经第一阀门11、第二阀门12传输至执行模块13中。执行模块13中残留的控制空气经第七端B7、第六端B6排出至外部环境中,进而使得执行模块13的齿条或拉杆带动旋转轴上的齿轮或拨叉转动,以关闭控制阀门14。
本实施例中应用于废气处理系统的阀门控制装置在关闭控制阀门时,仅需控制第一阀门和第二阀门的状态,即可将执行模块中的控制空气直接经第二阀门排出,以关闭控制阀门,加快了关闭控制阀门的进程,提升了应用于废气处理系统的阀门控制装置的响应能力。
图4为本申请实施例提供的另一种应用于废气处理系统的阀门控制装置的结构示意图,在图3所示的应用于废气处理系统的阀门控制装置的基础上,参考图4,当应用于废气处理系统的阀门控制装置包括定位模块15时,控制模块10收到快速开启控制阀门指令时,控制第一阀门11得电、第二阀门12得电,使得气体输入端A1与第一端B1连接,第二端B2与第六端B6连接,第七端B7与执行模块13的输入端连接,进而将控制空气直接经第一阀门11、第二阀门12输入执行模块13中。同时,定位模块15的输出端与作为第一阀门的截止端连接,控制空气经定位模块15流入第一阀门11后,在第一阀门11内截止,无法继续向第二阀门传输。
控制模块10收到控制阀门开启程度调节指令时,第一阀门11与气体输入端A1、定位模块15的连接情况、以及第一阀门11和第二阀门12的连接情况、第二阀门12和执行模块13的连接情况与图2的相同,本实施例在此不再赘述。
控制模块10接收到快速关闭控制阀门指令时,控制第一阀门11失电、第二阀门12得电,使得气体输入端A1与第三端B3连接,第四端B4作为第三输入选择端A4与定位模块15的输出端连接,第五端B5与第八端B8连接,第七端B7与执行模块13的输入端连接。因此,控制空气经气体输入端A1直接进入第一阀门11后,在第一阀门11内截止,无法继续向第二阀门12传输。控制空气经定位模块15输入第一阀门11、第二阀门12后,在第二阀门12内截止,也无法流入执行模块13中,至此,控制空气无法从气体输入端A1向执行模块13中传输。执行模块13中残留的控制空气经第七端B7、第六端B6排出至外部环境中,进而使得执行模块13的齿条或拉杆带动旋转轴上的齿轮或拨叉转动,以关闭控制阀门14。图4中仅以控制模块10收到快速关闭控制阀门指令时各 器件的连接状况为例。
本实施例提供的应用于废气处理系统的阀门控制装置,不仅可通过第一阀门、第二阀门实现对控制阀门的快速开启,通过第二阀门实现控制阀门的快速关闭,还可通过定位模块实现对控制阀门开启程度的调节,以满足用户需求,使得应用于废气处理系统的阀门控制装置的功能更为齐全。
图5为本申请实施例提供的另一种应用于废气处理系统的阀门控制装置的结构示意图,参考图5,可选的,应用于废气处理系统的阀门控制装置还包括输入阀门16,输入阀门16的输入端与气体输入端A1连接,输入阀门16的输出端与第一输入选择端A2连接;输入阀门16设置为过滤控制空气,并将控制空气的压力维持在设定值。
输入阀门16可以为过滤减压阀,可以过滤控制空气中的水分和颗粒物,并起到一定的稳压作用,将控制空气中的压力维持在6-8bar。
继续参考图5,可选的,应用于废气处理系统的阀门控制装置还包括加速模块17,加速模块17的输入端与第二输出选择端U2连接,加速模块17的输出端与执行模块13的输入端连接,加速模块17设置为加大控制空气在第二阀门12和执行模块13之间的流通速度和流量。
加速模块17中流通路径较宽,可加大控制空气在第二阀门12和执行模块13之间的流通速度和流量。同时加速模块17正常工作时,需要不断向自身输入气体,可通过将气体输入端A1与加速模块17连接以保证加速模块17的正常工作,在应用于废气处理系统的阀门控制装置包括输入阀门16时,可通过将输入阀门16的输出端与加速模块17连接,以使得加速模块17中不断输入气体。值得注意的是,控制空气经第二阀门12、加速模块17流入执行模块13中时,控制空气在加速模块17中的路径与气体输入端A1(或输入阀门16)直接流入加速模块17中以保证加速模块17正常工作的路径相互独立,进而使得控制加速模块17正常工作的气体不会流入执行模块13中,对控制阀门14的开闭造成影响。
