具体实施方式
下面详细描述本申请的实施例，所述实施例的示例在附图中示出。下面通过参考附图描述的实施例是示例性的，旨在用于解释本申请，而不能理解为对本申请的限制。
本实施方式提供一种具有消音功能的单通阀，也就是说该单通阀不但具有阀门控制的作用，同时还具有消音的功能，该单通阀可作为一个独立的部件用于空调系统，在使用时可直接安装到空调的相应位置，在生产时，可作为一个独立的部件加工制造，在销售时，可作为一个独立的部件销售。
具体地，参阅图1，本实施方式提供的单通阀包括：阀体10和消声管20；其中，阀体10具有进气口11和出气口12；冷媒能够从进气口11进入阀体10然后从出气口12流出； 消声管20的入口与出气口12连通，消声管20内形成有消音腔24，从而从出气口12流出的冷媒进入消音腔24内，在消音腔24内能够对冷媒流动的噪音进行消除或减弱，进一步，消音腔24内设置有过滤部件30，用于过滤冷媒中的杂质。
其中，阀体10本身的内部结构不是本申请的主要改进内容，在此不予介绍，本领域技术人员可根据常规技术实施。
在一种实施例中，消声管20与阀体10可以一体成型，两者为一个整体不可分割，从而提高两者的连接可靠性。
消音腔24的内径大于出气口12的直径，本领域技术人员可以调整消音腔24的内径从而实现对特定频率的噪音进行消除或减弱的目的。消音腔24的内径可以是固定不变的，也可以是在不同的位置设置不同尺寸的内径，从而满足特定的消音目的。
通过上述方案，单通阀不但具有控制冷媒流通和关闭的功能，同时具有消音功能，阀体10和消声管20集成为一体，可进行批量生产，在安装到空调系统时能够使空调系统结构更紧凑，而且由于阀体10和消声管20集成为一体，因此两者在投入空调系统使用时不必再进行焊接操作，不仅提高了两者的连接可靠性，还简化了在空调系统安装的便捷性。
在一种实施例中，过滤部件30为过滤网，过滤网的形状为圆台筒状，过滤网与消声管20同轴设置。由于过滤网的形状为圆台筒状，圆台的斜面能够更好的对杂质进行过滤，当然过滤网的形状也可以为圆锥状，从而使流通面全部为斜面。
在一种实施例中，过滤部件30的直径沿着从消声管20的入口向消声管20的出口的方向逐渐减小，这里的“从消声管20的入口向消声管20的出口的方向”为图1中的从上至下的方向。这种设置能够使得杂质更多地堆积在过滤网的周边，减少在流通面上堆积，从而保证冷媒通畅地流通。
进一步，过滤网的端部固定在消音腔24内的靠近消声管20的出口的一端，也就是如图1中的消音腔24的底端。过滤网的长度可以为消音腔24长度的1/3-2/3，这样既保证了良好的消音效果，又保证了良好的过滤效果。在图1中，过滤网的长度约为消音腔24长度的1/2。
消声管20的结构具体为中间粗两端细的管状结构，为了安装过滤网，可以将消声管20分割成两部分，待安装好过滤网后再将两部分焊接好，为了便于安装过滤网，可以在消音腔24内设置用于卡接过滤网的卡槽，圆台筒状的过滤网可以直接插在卡槽内，操作便捷，而且连接稳定。
在一种实施例中，为了节省成本，消声管20可采用不锈钢材质，其使用效果和现有的铜材质的使用效果基本无差别，但是不锈钢材质的消声管20价格相对较低，能够节省制造成本。阀体10也可采用不锈钢材质，消声管20和阀体10可以直接焊接。由于阀体10和 消声管20均为不锈钢材质，因此焊接效果好，焊接后不易发生电化学腐蚀的反应。
在一种实施例中，消声管20可以和阀体10一体成型地设置，也可以是先独自加工，然后焊接到一起。参阅图2-图3，消声管20的入口形成有入口管21，入口管21内壁焊接固定有铜套22；阀体10具出气铜管121，出气口12形成于出气铜管121，出气铜管121插入铜套22，并与铜套22焊接固定。也就是说消声管20和阀体10均设置了与彼此相连的管。由于现有的已投入使用的空调中的部分阀体10的出气铜管121多采用铜质，而消声管20又采用不锈钢材质，因此两者的焊接相对复杂一些，为此，本实施例先在入口管21内壁焊接铜套22，由于铜套22尺寸较小，而且和入口管21的尺寸可以配合的更好，因此两者更容易焊接，入口管21和铜套22焊接好后，在将出气铜管121和铜套22进行焊接，由于都是铜材质，因此焊接相对容易。
由此，在入口管21内壁焊接铜套22的步骤可以提前实施，而且入口管21和铜套22的结构简单，实施焊接时基本不受焊接设备的限制，可操作性较强，焊接效果也更容易保障。通过在入口管21内壁焊接铜套22可以降低现有阀体10和不锈钢材质的消声管20焊接的难度。
在一些实施例中，消声管20的出口连接有出口延长管23。出口延长管23可以与消声管20焊接，具体地，消声管20与出口延长管23采用激光焊接或钎焊连接。出口延长管23为弯曲的钢管，以便于与其他部件进行连接。
具体地，消声管20的出口可以形成具有一定长度的出口管，该出口管和入口管21类似，如图1和2所示，出口延长管23的端部插入该出口管内，并与该出口管焊接固定。这样能够提高焊接的可靠性，保证密封效果。在其他实施例中，也可以设置将出口管直径小于出口延长管23的直径，从而将出口管的端部插入出口延长管23内进行焊接。
本实施方式进一步提供一种空调系统，包括上述任意一实施例的单通阀，使用这种单通阀，安全可靠，不必再安装过滤部件和消音部件，使得空调系统结构更加紧凑，安装也便捷许多，大大提高了生产效率。
在一种实施例中，消声管20竖直放置，消声管20的入口朝上，消声管20的出口朝下，具体为如图1和2所示的方式放置，如此设置，使得流入消音腔24内的冷媒与过滤网更均与的接触，同时使杂质更均匀地分散在过滤网周边位置，减少杂质对流通面的堵塞，保证冷媒流通通畅。
