The refrigerant flowing through the valve is often in a gas-liquid two-phase mixed state, and there will be different sizes in the fluid in the pipeline. Uniform bubbles, the flow area suddenly shrinks when the bubbles flow through the throttling valve port, which causes the larger diameter bubbles to burst and produce larger noise, and the noise is discontinuous, which affects the comfort of the user using the equipment.

When the fluid flows through the muffler plate 141, the large bubbles pass through the muffler plate 141. The upper guide hole 142 is decomposed into smaller bubbles, and then the fluid enters the mixed flow cavity 143, where the mixed flow agitates in the mixed flow cavity 143, and further breaks up the bubbles, thereby fully reducing the bubbles in the fluid and reducing the flow of fluid. Noise when passing the electronic expansion valve 100.

可以理解的是，流体在流经一层消音板141板后进入混流腔143，会在混流腔143内产生顺时针或逆时针方向的旋转，后续的流体流入混流腔143时，能够使流体中的大气泡被充分的细化。It is understandable that the fluid enters the mixed flow cavity 143 after flowing through a layer of muffler plate 141, which will generate clockwise or counterclockwise rotation in the mixed flow cavity 143. When the subsequent fluid flows into the mixed flow cavity 143, the fluid can be The large bubbles are fully refined.

需要说明的是，所述一层消音板141上，可以有多重形状的导流孔142，相邻块之间的消音板141的导流孔142也可以设置为不同的形状。It should be noted that the one-layer sound-absorbing plate 141 may have multiple-shaped diversion holes 142, and the diversion holes 142 of the sound-absorbing plates 141 between adjacent blocks may also be arranged in different shapes.
可以理解的是，不同的孔型对气泡的切分效果不同，在同一消音板141上设置不同形状的导流孔142，能够使得进入混流腔143内的流体状态呈多样化，从而提高混流腔143内流体的混流效果，而将多层消音板141的导流孔142设置为不同形状使得不同层的消音板141能够互相配合，对气泡进行不同形式的分切，提高消音板141消除大气泡的效果。It can be understood that different hole types have different effects on the segmentation of bubbles. The provision of diversion holes 142 of different shapes on the same muffler plate 141 can make the state of the fluid entering the mixed flow cavity 143 diversified, thereby improving the mixed flow cavity The mixing effect of the fluid in 143, and the guide holes 142 of the multi-layer silencer 141 are arranged in different shapes so that the different layers of the silencer 141 can cooperate with each other, and the bubbles are divided in different forms to improve the silencer 141 to eliminate large bubbles Effect.

可以理解的是，将相邻两块消音板141上的导流孔142错位设置，能够使得流入混流腔143的气液混合流体经过混合后再进入下一层的消音板141的导流孔142内，以提高混流腔143的混流效果，避免了由于相邻两块消音板141间距过小，导致流体直接流过两层消音板141，而没有进行充分的混流，降低了对大气泡的细化效果。It can be understood that the dislocation of the diversion holes 142 on the two adjacent muffler plates 141 can make the gas-liquid mixed fluid flowing into the mixed flow cavity 143 enter the diversion holes 142 of the muffler plate 141 of the next layer after being mixed. In order to improve the mixing effect of the mixed flow cavity 143, it is avoided that the distance between two adjacent muffler plates 141 is too small, which causes the fluid to directly flow through the two muffler plates 141 without sufficient mixing, which reduces the fineness of large bubbles. Effect.
值得一提的是，所述导流孔142的孔径大小可以是0.15毫米至2毫米之间，例如0.15毫米、0.16毫米、1毫米、1.2毫米、1.5毫米、1.8毫米、2毫米或其他在0.15毫米至2毫米之间的数值，并大于空调制冷***内的滤网的孔径，从而能够避免所述阀门消音器14被能够通过管路内的过滤装置的杂质阻塞。It is worth mentioning that the aperture size of the diversion hole 142 can be between 0.15 mm and 2 mm, such as 0.15 mm, 0.16 mm, 1 mm, 1.2 mm, 1.5 mm, 1.8 mm, 2 mm, or other diameters within 0.15 mm.
