相关申请
本申请要求2019年6月13日申请的，申请号为201920890465.7，发明名称为“阀门消音器及其电子膨胀阀”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及制冷设备技术领域，特别是涉及阀门消音器以及电子膨胀阀。
背景技术
膨胀阀是制冷系统中的一个重要部件，一般安装于冷凝器和蒸发器之间。电子膨胀阀是膨胀阀中的一种，通过控制步进电机控制膨胀阀的开度，进而达到调节供液量的目的。无级变容量制冷系统，制冷供液量调节范围宽，要求调节反应快，传统的节流装置(如热力膨胀阀)难以良好胜任，而电子膨胀阀可以很好地满足要求。
但一般的电子膨胀阀在使用中，由于冷媒中往往为气液混合状态，流经阀芯口的流体被大幅加速而出现较大的噪音影响舒适度。
发明内容
申请根据本申请的各种实施例，提供一种阀门消音器，所述阀门消音器包括：
本体，具有一端开口的容置腔，所述本体的侧壁上开设有多个与所述容置腔连通的通孔，且所述通孔的延伸方向与本体延伸方向倾斜或垂直；
连接部，设置于本体的开口处。
上述技术方案的优点在于：冷媒从本体的开口端或侧面流入，并通过通孔流出，使得冷媒在通过电子膨胀阀时流经阀门消音器，受到阀门消音器的阻挡，流过阀门消音器的通孔后分为多股冷媒，使得多股冷媒在出液侧得到进一步混合，从而消除冷媒中的大气泡，细化气泡以降低噪音。
在其中一个实施例中，所述本体呈管状或漏斗状。
在其中一个实施例中，所述通孔从容置腔内向外逐渐远离开口的一端。如此设置，使得冷媒流经阀门消音器时，受到的阻滞更小。
在其中一个实施例中，多个所述通孔间隔均匀分布于本体上。如此设置，使得冷媒能够均匀的被分散为多股从阀门消音器的出液侧流出。
在其中一个实施例中，所述连接部呈环形，且由开口向本体外侧延伸。所述连接部用于连接于电子膨胀阀以及管路之间。
在其中一个实施例中，所述连接部包括呈环形的第一连接部以及呈管状的第二连接部，且所述第二连接部的直径大于所述开口的直径。所述第二连接部贴合于电子膨胀阀内，从而使得阀门消音器不会摆动，使得阀门消音器的连接更稳定。
本申请还提供一种电子膨胀阀，包括前述的任意一种阀门消音器。
在其中一个实施例中，所述电子膨胀阀还包括：
阀体，具有进口以及出口；
进管，连接于所述进口；
出管，连接于所述出口，
所述阀门消音器设置于所述进口和/或所述出口处。
在其中一个实施例中，所述电子膨胀阀包括设置于进口处的第一消音器 和/或设置于出口处的第二消音器。
在其中一个实施例中，所述第一消音器的连接部卡接于所述阀体与所述进管之间，所述本体位于所述进管内。

除非另有定义，本文所使用的所有的技术和科学术语与属于本申请的技术领域的技术人员通常理解的含义相同。本文中在本申请的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本申请。本文所使用的术语“或/及”包括一个或多个相关的所列项目的任意的和所有的组合。
本申请提供一种电子膨胀阀100，所述电子膨胀阀100包括：阀体110、进管120、出管130以及阀门消音器140。
具体的，所述阀体110具有进口111以及出口112；所述进管120连接于所述进口111；所述出管130连接于所述出口112，所述阀门消音器140设置于所述进口111和/或所述出口112处，以降低冷媒流过阀体110时产生的噪音。需要说明的是，冷媒中混有气泡，当气泡体积过大时，在流入阀体110时会产生间断的较大噪音，当冷媒流出阀体110时，由于在出口112处的流速增快，导致冷媒产生湍流，发出较大的噪音，若此时冷媒中混有较大气泡，也会进一步产生间断的较大噪音，影响使用者的舒适度，故在阀体110进口111处设置阀 门消音器140可以有效减少大气泡数量，减小间断性的较大噪音，而在阀体110出口112处设置阀门消音器140，则可以在冷媒流过阀体110后，对流向混乱的冷媒进行引导，并进一步消除不均匀气泡，减少阀体110出口112处的噪音，且消除大气泡能够进一步减少整体管路中的噪音。
所述阀门消音器140包括：本体141以及设置于本体141上的连接部142，所述本体141具有一端开口的容置腔，所述本体141的侧壁上开设有多个与所述容置腔连通的通孔143，且所述通孔143的延伸方向与本体141延伸方向倾斜或垂直；所述连接部142设置于本体141的开口处。
通过设置所述阀门消音器140，冷媒从本体141的开口端流入，并通过通孔143后从侧面流出或者从本体141的侧面通过通孔143流入，并从开口端流出，使得冷媒在通过电子膨胀阀100时流经阀门消音器140，受到阀门消音器140的阻挡，流过阀门消音器140的通孔143后分为多股冷媒减小气泡，并使多股冷媒在出液侧得到进一步混合，从而消除冷媒中的大气泡，细化气泡以降低噪音。
优选的，所述通孔143从容置腔内向外并逐渐远离开口一端开设。如此设置，使得冷媒流经阀门消音器140时，受到的阻滞更小。
在另一实施方式中，所述通孔143也可以朝向本体141轴线且垂直于轴线方向开设。
优选的，多个所述通孔143间隔均匀分布于本体141上。如此设置，使得冷媒能够均匀的被分散为多股从阀门消音器140的出液侧流出。
在其中一种实施方式中，所述连接部142呈环形，且由开口向本体141外侧延伸。所述连接部142安装于阀体110以及管路之间。
在另一实施方式中，所述连接部142包括呈环形的第一连接部1421以及 呈管状的第二连接部1422，且所述第二连接部1422的直径大于所述开口的直径。所述第二连接部1422贴合于阀体110内，从而使得阀门消音器140不会摆动，使得阀门消音器140的连接更稳定。
下面结合附图对具体实施方式进行解释说明：
如图5至和图6所示，在第一种实施方式中，所述本体141呈管状，所述通孔143均匀分布于所述本体141的侧面。
如图7和图8所示，在第二种实施方式中，所述本体呈管状，所述通孔
如图9和图10所示，在另一实施例中，所述本体141呈漏斗状，且底部封闭设置，所述通孔143均匀分布于锥面上。将本体141设置为漏斗状，当冷媒从本体141外侧通过本体141上的通孔143流入本体141后，多股冷媒相互交汇以减小大气泡的数量，且锥形的结构能够减小阀门消音器140对冷媒的阻滞；当冷媒从本体141内侧通过通孔143流出本体141后，相对于呈管状的本体结构，由于增大了本体141与管壁之间的空间，从而能够减小对冷媒的阻滞作用。
优选的，所述阀门消音器140的连接部卡接于所述阀体110与所述进管120之间，所述本体141位于所述进管120内。
优选的，所述阀体110的出口112处设置有连接座113，所述阀门消音器140设置于所述连接座113上从而连接在所述阀体110上。当然，所述阀体110也可以一体设置，所述阀门消音器140设置于所述阀体110上。
下面结合附图对阀门消音器140的具体设置方式进行解释说明：

如图2所示的第二种实施方式中，所述阀体110的进口111处设置有阀门消音器140，所述阀门的出口112处也设置有阀门消音器140，所述出口112处的阀门消音器140的设置方式与第一种实施方式中的相同，所述进口处的阀门消音器140的连接部142设置于所述阀体110以及进管120之间，所述进管120焊接于所述阀体110上，且所述阀门消音器140的本体141伸入所述进管120内。
如图3所示的第三种实施方式中，所述阀门消音器140设置于出口112处，且所述阀体110的出口112呈锥形，具体的，所述阀体110的出口112处设置有连接座113，所述阀门消音器140设置于所述连接座113上从而连接在所述阀体110上，所述阀门消音器140的连接部141焊接于连接座113上或者通过过盈配合连接于连接座113或者通过连接座113的缩口设置连接于所述连接座113上，且所述连接座113伸入所述出管130内。
如图4所示的第四种实施方式中，所述阀体110的进口111处设置有第一阀门消音器140，所述阀体110的出口112处设置有阀门消音器140，所述阀门消音器140的连接部142均包括呈环形的第一连接部1421以及呈管状的第二连接部1422，所述进口111处的阀门消音器140的第二连接部1422贴合于进管120内壁，所述出口112处的阀门消音器140的第二连接部1422贴合于阀体110内壁，使得所述阀门消音器140不会侧向摆动，所述进管120以及出管130通过设置形变凸起固定所述阀门消音器140的第二连接部1422从而固定所述阀门消音器140。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些 技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
