通过在消声块组100上设置多个消声通道101和至少一个第一通过流道102，第一通过流道102的流通截面积大于多个消声通道101中的最小流通截面积，这样能够在介质通过消声块组100的过程中，介质中的杂质能够通过第一通过流道102，以避免介质中的杂质堆堵在消声通道101内导致的影响消声块组100的消音效果。
在本申请的第一个实施例中，消声块组100包括消音组本体，至少一个第一通过流道102和多个消声通道101均设置在消音组本体中。其中，将消音组本体设置在阀体的阀口处或者管路内或者阀体与管路结合的位置，以在介质流经消音组本体的过程中起到消音的效果，同时，利用第一通过流道102的设置使介质中的杂质能够顺流，避免对消声通道101产生封堵，影响消音效果。

在本申请提供的第三个实施例中，消声块组100还包括消音组本体，多个消声通道101和至少一个第一通过流道102均设置在消音组本体上；消音组件还包括：支撑架200，设置在第二安装腔32内，支撑架200上设置有多个第二通过流道201，多个第二通过流道201间隔设置，消音组本体设置在支撑架200上。根据本申请实施例中的消音组件，包括消声块组100和支撑架200，消声块组100的消音组本体上设置多个消声通道101和至少一个第一通过流道102，第一通过流道102的流通截面积大于多个消声通道101中的最小流通截面积；支撑架200上设置有多个第二通过流道201，多个第二通过流道201间隔设置，消声块组100设置在支撑架200上。其中，利用消声块组100中的多个消声通道101，在介质通过的过程中降低噪音，利用第一通过流道102，将第一通过流道102的流通截面积大于多个消声通道101中的最小流通截面积，这样在介质流通的过程中，避免了介质中的杂质堆堵在消声块组100上，介质中 的杂质可在第一通过流道102内通过，配合支撑架200上的第二通过流道201，在保证了消音效果的同时，避免了消声块组100中的第一通过流道102出现脏堵的情况，提高了消音组件的可靠性。
具体地，消音组本体包括：第一消声块11，设置在支撑架200的第一侧；第二消声块12，设置在支撑架200的第二侧，第一消声块11的正投影的投影面积大于第二消声块12的正投影的投影面积，或，第一消声块11的正投影与第二消声块12的正投影重合；第一消声块11和第二消声块12上均设置有多个消声通道101；第一消声块11和/或第二消声块12上设置有至少一个第一通过流道102。在具体实施时，第一消声块11和第二消声块12上分别设置有至少一个第一通过流道102；或者，仅在第一消声块11上设置有1个第一通过流道102，在第二消声块12上仅设置多个消声通道101。在使用过程中，介质进入或离开消音组件的过程中，介质中的气泡会被第一消声块11上的多个消声通道101和第二消声块12上的多个消声通道101细化为细小气泡，同时设置了第一通过流道102避免了多个消声通道101完全脏堵。此外，第一消声块11和第二消声块12沿介质流通通道的延伸方向依次间隔设置，这样介质在第一消声块11和第二消声块12的共同作用下，提高消音组件的消音效果。
其中，正投影是指第一消声块11和第二消声块12在水平面上的投影。
在具体实施的过程中，第一消声块11上设置有至少一个第一通过流道102，第一消声块11上的各个第一通过流道102的至少部分与第二消声块12上的多个消声通道101相对。这样设置当介质流动过程中，当介质流经多个消声通道101的过程中，若介质内杂质过多，一部分介质留在第二消声块12上，另一部分杂质通过第一消声块11上的多个第一通过流道102流出，这样避免了第一消声块11和第二消声块12上的消声通道101均发生脏堵，以影响消音效果。当介质反向流动时，可直接将第二消声块12上残留的杂质带出。
在本申请的第一消声块11的第一个实施例中，如图5所示，第一消声块11的中部设置有第一通过流道102，此时第二消声块12上的消声通道101设置在第二消声块12的中部。
在本申请的第一消声块11的第二个实施例中，如图6所示，多个第一通过流道102设置在第一消声块11的边缘，此时第二消声块12上的消声通道101设置在第二消声块12的边缘。
在本申请提供的实施例中，如图3所示，支撑架200包括：支撑本体20，支撑本体20上设置有安装开口202，多个第二通过流道201环绕安装开口202设置；凸出本体21，设置在支撑本体20上，凸出本体21沿圆周方向延伸，以围成与安装开口202连通的安装通道210，第二消声块12设置在安装通道210内。在介质流动的过程中，一部分介质利用第二消声块12上的消声通道101进行消音，另一部分介质通过支撑本体20上的第二通过流道201流至第一消声块11上的消声通道101达到消音效果，同时，介质中的杂质可直接通过第二通过流道201附着在第一消声块11，在介质反向流动时将第一消声块11上的介质带出并通过支撑本体20上的第二通过流道201流出，即保证了消音效果，又对第一消声块11和第二消声块12起到了清洁作用。
具体地，支撑本体20上的多个第二通过流道201的至少部分与第一消声块11上的多个消声通道101相对。由于第二通过流道201对介质的消音能力较消声通道101较差，通过将支撑本体20上的多个第二通过流道201的至少部分与第一消声块11上的多个消声通道101相对，能够使介质在流经第二通过流道201之后，立刻利用第一消声块11上的消声通道101进行消音，以避免噪声过大。
为了方便安装第二消声块12，安装通道210的内壁面上设置有限位凹槽211，限位凹槽211沿安装通道210的周向方向延伸，第二消声块12设置在限位凹槽211内。这样利用限位凹槽211的相对的两个槽壁面对第二消声块12进行止挡，以在第二消声块12受到介质冲击时保持稳定。
在具体实施的过程中，支撑架200还包括：翻边22，设置在支撑本体20的缘边并朝向远离凸出本体21的方向延伸，翻边22绕支撑本体20的周向方向设置，第一消声块11设置在翻边22上。通过设置翻边22，使第一消声块11与支撑本体20之间具有间隙，利用此间隙对介质起到缓冲的效果，避免介质在流经第一消声块11之后直接冲击到支撑本体20上或者流经支撑本体20后直接冲击到第一消声块11上，造成介质能量损失较大，影响整个介质循环系统的运行。优选地，第一消声块11的连接端面至支撑本体20围成安装开口202的端面之间的距离(即翻边22的高度)为0.2mm至3mm，优选为0.8mm，这样以保证第一消声块11与第二消声块12之间的距离达到最优的降噪效果。
优选地，多个消声通道101的平均内径小于0.15mm。这样以对介质中的气泡均匀细化，提高消音效果。
本申请中的消音组件，能够固定在阀体部件上或者管件中或者管件与阀体的连接处，当介质通过消音组件的过程中，能够起到消音效果。
通过第一消声块11和第二消声块12共同作用，优化了降噪效果的同时，由于设置了第一通过流道102和第二通过流道201，能够弥补第一通过流道102和第二通过流道201对介质的压力所带来的影响以及对降噪所带来的影响，同时还解决了介质中的杂质容易封堵消声通道101的问题。
其中，阀体1内设置有阀口，消声块组100和支撑架200均安装在阀口内，第一通过流道102的流通截面积大于等于阀口截面积的二分之一。第二通过流道201的流通截面积大于等于阀口截面积的二分之一，这样能够避免消声通道101内发生脏堵，同时避免了介质在通过第一通过流道102或第二通过流道201的过程中出现明显降压。
如图7所示，本申请还提供了一种空调系统，包括冷媒流通回路500和膨胀阀600，膨胀阀600设置在冷媒流通回路500上，膨胀阀600为上述的膨胀阀600。
空调系统还包括过滤器，过滤器设置在冷媒流通回路500上，消音组件中的第一通过流道102的流通截面积大于过滤器中过滤网的最小网孔的流通截面积。
具体地，过滤器包括第一过滤器700和第二过滤器800，第一过滤器700和第二过滤器800间隔设置在冷媒流通回路500上，膨胀阀600位于第一过滤器700和第二过滤器800之间。其中，冷媒流通回路500上还设置有蒸发器501和冷凝器502。在实际应用过程中，两相制冷剂在冷媒流通回路500内进行循环，制冷剂在通过膨胀阀600的过程中，利用消音组件中的第一消声块11和第二消声块12中的消声通道101将制冷剂中的气泡细化，能够起到消音的效果，同时，因为设置了第一通过流道102和第二通过流道201，能够避免制冷剂中的杂质封堵消声通道101，而未在第一过滤器700中进行过滤的杂质，在通过第一通过流道102和第二通过流道201之后，能够继续利用第二过滤器800实现过滤，进而提高了空调系统运行的可靠性，当杂质封堵在消声通道101时，可在制冷剂反向流动时将消声通道101内的杂质带出，达到清洁作用，延缓脏堵时间。
从以上的描述中，可以看出，本申请上述的实施例实现了如下技术效果：
根据本申请提供的一种膨胀阀，包括阀体1和阀针2，膨胀阀还包括导向套筒3和消音组件400，导向套筒3设置在阀体1内，导向套筒3内设置有相互连通的第一安装腔31和第二安装腔32；其中，阀针2的至少部分设置在第一安装腔31内并沿第一安装腔31的延伸方向移动；消音组件400，包括消声块组100，消声块组100包括多个消声通道101和至少一个第一通过流道102，消音组件400设置在第二安装腔32内。这样设置将消音组件400集成在导向套筒3内，在装配阀体的过程中，可以直接将导向套筒3安装在阀体1内与阀针2配合，在冷媒流经消音组件400之后直接流入到第一安装腔31内，这样设置将消音组件400集成在导向套筒3内，在冷媒流经消音组件400之后直接流入到第一安装腔31内，即冷媒在导向套筒3内依次流经第二安装腔32和第一安装腔31，在此过程中避免了由于阀前两相流体不稳定，气泡大小不一导致的冷媒流动不连续产生的噪声，通过导向套筒3对阀座芯与阀座进行了集成，使膨胀阀的结构更加简单，优化了装配工艺。
需要说明的是，本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请的实施方式例如能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
为了便于描述，在这里可以使用空间相对术语，如“在……之上”、“在……上方”、“在……上表面”、“上面的”等，用来描述如在图中所示的一个器件或特征与其他器件或特征的空间位置关系。应当理解的是，空间相对术语旨在包含除了器件在图中所描述的方位之外的在使用或操作中的不同方位。例如，如果附图中的器件被倒置，则描述为“在其他器件或构造上方”或“在其他器件或构造之上”的器件之后将被定位为“在其他器件或构造下方”或“在其他器件或构造之下”。因而，示例性术语“在……上方”可以包括“在……上方”和“在……下方”两种方位。该器件也可以其他不同方式定位(旋转90度或处于其他方 位)，并且对这里所使用的空间相对描述作出相应解释。
以上仅为本申请的优选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
