Technical Problem
但是，D粗管仅依靠两端的端口边缘与阀体以及导管连接，连接面积小，导致连接不牢靠
Benefits of technology
[0016]与现有技术相比，本申请提供的四通阀，通过在阀体开设第一通孔，以及在导管开设第二通孔，并使通气管一端连接第一通孔，另一端连接第二通孔，使得通气管直接连通阀体与导管，避免了传统四通阀需要在D接管上开孔导致D接管强度削弱而容易在压缩机振动工况下疲劳断裂的问题。并且，相较于相关结构中，D粗管仅依靠两端的端口边缘与阀体以及导管连接的方式，本申请通过设置支架，且支架的第一连接面与阀体连接，第二连接面与导管连接，支架作为支撑件在导管与阀体之间提供额外支撑作用，从而有利于提升导管与阀体支撑连接的牢固程度与可靠程度，提升了四通阀在压缩机振动工况下抗松动以及抗开裂的能力。并且，通过在支架上设置容纳空间、第一孔及第二孔，通气管与支架进行结构集成，减少了通气管所需的额外空间，使得四通阀结构更加紧凑。

Abstract
The application relates to a four-way valve which comprises a valve body, a conduit, an air pipe and a support, the valve body is provided with a first through hole, the conduit is provided with a second through hole, the support is provided with a first connecting surface and a second connecting surface, the first connecting surface is connected with the valve body, the second connecting surface is connected with the conduit, the support is provided with a containing space, the support comprises a first hole and a second hole, the first hole is arranged through the first connecting surface, the second hole is arranged through the second connecting surface, the first hole and the second hole are respectively communicated with the containing space, part of the air pipe is located in the containing space, one end of the air pipe is arranged through the first hole and connected with the first through hole, and the other end of the air pipe is arranged through the second hole and connected with the second through hole. The four-way valve provided by the application avoids the problem that the traditional four-way valve needs to be provided with a hole on the D connecting pipe, so that the strength of the D connecting pipe is weakened and the D connecting pipe is easily broken under the vibration working condition of a compressor, and reliable support can be realized between the valve body and the conduit through the support.
