The through holes are arranged obliquely with respect to the axis of the body, and the inclination direction of each through hole is the same, so that the medium passing through the valve muffler is in a rotating state through the drainage of the through hole, so that the medium enters and exits. After the liquid side is further mixed, bubbles with larger diameters are eliminated, and the size of the bubbles is uniform, thereby reducing noise during the flow process and achieving the effect of noise reduction.

In this way, the medium can exhibit regular rotation after flowing through the valve muffler, reducing the cross-collision of multiple fluids to control noise. It should be noted that the noise generated by the rotation of the fluid is small, while the violent collision of multiple fluids It will cause the expansion of noise, so when increasing the rotation of the fluid itself to improve the mixing effect, minimize the cross impact between the fluids to suppress the generation of noise.

如图1所示，在第一种实施方式中，阀门消音器140设置于阀体110的出口112内，阀体110的出口112位于出管130内；As shown in FIG. 1, in the first embodiment, the valve silencer 140 is disposed in the outlet 112 of the valve body 110, and the outlet 112 of the valve body 110 is located in the outlet pipe 130;
如图2所示，在第二种实施方式中，阀门消音器140设置于阀门进口111以及出口112内，作为一种优选的连接方式，进口111处的阀门消音器140被进管120抵接，从而将消音器140固定，结构简单，出管130内的阀门消音器140与第一种实施方式中的设置方式相同；As shown in Figure 2, in the second embodiment, the valve silencer 140 is arranged in the valve inlet 111 and the outlet 112. As a preferred connection method, the valve silencer 140 at the inlet 111 is abutted by the inlet pipe 120. , Thereby fixing the muffler 140, the structure is simple, and the valve muffler 140 in the outlet pipe 130 is arranged in the same manner as in the first embodiment;
如图3所示，在第三种实施方式中，阀门消音器140设置于阀体110的进口111以及出口112处，且进口111处的阀门消音器140设置于进管120内，通过使出管130管壁收缩变形以固定阀门消音器140，出口112处的阀门消音器140设置于出管130内，通过使出管130变形以固定阀门消音器140；As shown in FIG. 3, in the third embodiment, the valve silencer 140 is arranged at the inlet 111 and the outlet 112 of the valve body 110, and the valve silencer 140 at the inlet 111 is arranged in the inlet pipe 120. The tube wall of the tube 130 shrinks and deforms to fix the valve muffler 140, the valve muffler 140 at the outlet 112 is arranged in the outlet pipe 130, and the valve muffler 140 is fixed by deforming the outlet pipe 130;
如图4所示，在第四种实施方式中，所述阀体110上设置有连接座113，连接座113开设有出口112，出口112呈喇叭形，出口112靠近阀门消音器140的一端的直径大于远离阀门消音器140的一端的直径，阀门消音器140设置于喇叭形的出口112处。As shown in Figure 4, in the fourth embodiment, the valve body 110 is provided with a connecting seat 113, the connecting seat 113 is provided with an outlet 112, the outlet 112 is horn-shaped, and the outlet 112 is close to one end of the valve muffler 140 The diameter is larger than the diameter of the end away from the valve muffler 140, and the valve muffler 140 is arranged at the horn-shaped outlet 112.
连接座113还开设有开口114，开口114与出口112连通，开口114呈喇叭形，开口114靠近阀门消音器140的一端的直径小于远离阀门消音器140 的一端的直径。The connecting seat 113 is also provided with an opening 114 communicating with the outlet 112. The opening 114 is in a horn shape. The diameter of the end of the opening 114 close to the valve muffler 140 is smaller than the diameter of the end far away from the valve muffler 140.
可以理解，介质先经过开口114流出至出口112，介质在流动过程中，横截面积先是逐渐减少，再逐渐增大，对于介质的流动起到导向作用，能够减少介质流动的阻力。It can be understood that the medium first flows out through the opening 114 to the outlet 112. During the flow of the medium, the cross-sectional area first gradually decreases and then gradually increases, which can guide the flow of the medium and reduce the resistance to the flow of the medium.
如图7至10所示，阀门消音器140包括本体141，本体141具有相对设置的进液侧143和出液侧144，本体141上开设有多个贯穿本体141的通孔142，通孔142将进液侧143与出液侧144连通，且多个通孔142相对本体141的轴线呈顺时针方向倾斜设置或呈逆时针方向倾斜设置。As shown in Figures 7 to 10, the valve muffler 140 includes a body 141 having a liquid inlet side 143 and a liquid outlet side 144 oppositely arranged. The body 141 is provided with a plurality of through holes 142 passing through the body 141. The liquid inlet side 143 is connected to the liquid outlet side 144, and the plurality of through holes 142 are inclined in a clockwise direction or arranged in a counterclockwise direction with respect to the axis of the main body 141.
可以理解的是，通过在本体141上设置多个通孔142，使得介质在遇到阀门消音器140时被阻滞，且在流过阀门消音器140时被分隔为多股，将多个通孔142设置为均呈顺时针方向或均呈逆时针方向的倾斜状，使得通过阀门消音器140的通孔142的介质通过通孔142的引流而旋转，从而使冷介质在进入出液侧144后进一步混合，减少大气泡的数量，使得气泡大小均匀分布，从而在流动中减小噪音，达到消音的效果。It can be understood that by providing a plurality of through holes 142 on the body 141, the medium is blocked when it encounters the valve muffler 140, and is divided into multiple strands when flowing through the valve muffler 140. The holes 142 are arranged in a clockwise direction or both in a counterclockwise direction, so that the medium passing through the through hole 142 of the valve muffler 140 rotates through the drainage of the through hole 142, so that the cold medium enters the liquid outlet side 144. After further mixing, the number of large bubbles is reduced, so that the size of the bubbles is evenly distributed, thereby reducing noise in the flow and achieving the effect of noise reduction.
值得一提的是，通孔142围绕本体141的轴线均呈顺时针方向或逆时针方向倾斜的结构，具体而言，通孔142的形状可以是螺旋状的，也可以是倾斜的斜孔。可以理解的是，设置通孔142的结构是为了使介质形成旋转的状态，统一的设置为顺时针或逆时针倾斜即可实现介质的旋转。It is worth mentioning that the through hole 142 is inclined clockwise or counterclockwise around the axis of the main body 141. Specifically, the shape of the through hole 142 may be a spiral or an inclined oblique hole.

如此设置，使得介质流过阀门消音器140后呈现规则的旋转，减小多股流体的交叉碰撞，以控制噪音。需要说明的是流体的旋转产生的噪音较小，而多股流体的剧烈冲撞则会导致噪音的扩大，故而在提高流体本身的旋转以 提高混合效果时，尽量减小流体之间的交叉冲击可抑制其余噪音的产生。With this arrangement, the medium flows through the valve muffler 140 and then exhibits regular rotation, which reduces the cross collision of multiple fluids to control noise. It should be noted that the noise generated by the rotation of the fluid is small, and the violent collision of multiple fluids will cause the expansion of the noise. Therefore, when increasing the rotation of the fluid itself to improve the mixing effect, minimize the cross impact between the fluids. Suppress the remaining noise.
优选的，从进液侧143至出液侧144，通孔142的横截面积逐渐减小，利于介质的流动。可以理解，在介质流过通孔142时，通孔142的横截面积逐渐减少，能够对于介质的流动起到导向作用，若通孔142的横截面积是非逐渐减少的，则通孔142的内壁会形成台阶，对介质的流动产生阻滞。Preferably, from the liquid inlet side 143 to the liquid outlet side 144, the cross-sectional area of the through hole 142 gradually decreases, which facilitates the flow of the medium. It can be understood that when the medium flows through the through hole 142, the cross-sectional area of the through hole 142 gradually decreases, which can guide the flow of the medium. If the cross-sectional area of the through hole 142 does not gradually decrease, the cross-sectional area of the through hole 142 The inner wall will form steps, which will block the flow of the medium.
优选的，通孔142的横截面为圆形、椭圆形、方形、三角形、梯形或扇形中的任意一种。可以理解的是，本申请并不对于通孔142的横截面的形状加以限制，只要从进液侧143至出液侧144，通孔142的横截面积逐渐减小即可。Preferably, the cross section of the through hole 142 is any one of a circle, an ellipse, a square, a triangle, a trapezoid, or a fan shape. It can be understood that the present application does not limit the cross-sectional shape of the through hole 142, as long as the cross-sectional area of the through hole 142 gradually decreases from the liquid inlet side 143 to the liquid outlet side 144.
请参见图10，优选的，本体141的中心点处朝向进液侧143方向设置有锥形突起部145。可以理解，如此设置，使本体141进液侧143形成引流结构，导向介质的流动，使介质的流动更顺畅。Referring to FIG. 10, preferably, a tapered protrusion 145 is provided at the center point of the body 141 toward the liquid inlet side 143. It can be understood that this arrangement makes the inlet side 143 of the main body 141 form a drainage structure to guide the flow of the medium and make the flow of the medium smoother.
优选的，本体141沿轴线方向的厚度范围在1毫米至5毫米之间。Preferably, the thickness of the main body 141 in the axial direction ranges from 1 mm to 5 mm.
进一步的，本体141的厚度范围在3毫米至5毫米之间。可以理解的是，通过增加本体141的厚度，通孔142的厚度也随之加大，能够加强对于介质的引流效果，从而增加介质的旋转，提高对大气泡的消除效果。Further, the thickness of the body 141 ranges from 3 mm to 5 mm. It can be understood that by increasing the thickness of the main body 141, the thickness of the through hole 142 is also increased, which can enhance the drainage effect of the medium, thereby increasing the rotation of the medium and improving the effect of eliminating large bubbles.
可以理解的是，上述阀门消音器140并不限于使用在本申请提供的电子膨胀阀100中，阀门消音器140还可应用于在别的阀门中，例如设置于制冷***中的热力膨胀阀、电磁阀中等，阀门消音器140还可设于供暖***中的球阀中或其他管路***的阀门中均可起到消音的效果。It can be understood that the valve silencer 140 described above is not limited to being used in the electronic expansion valve 100 provided in this application. The valve silencer 140 can also be used in other valves, such as thermal expansion valves, Solenoid valves, etc., the valve silencer 140 can also be installed in the ball valve in the heating system or in the valves of other piping systems, which can have the effect of silencer.
