As shown in fig. 1, the valve body 1 is provided with a water inlet 21 for water to flow into the solenoid valve and a water outlet 31 for water to flow out of the solenoid valve. Wherein, the water inlet 21 flows into the water inlet cavity 2, and the water outlet 31 is communicated with the water outlet cavity 3. Fig. 3 is a schematic structural diagram of the valve body 1 in this embodiment, the water outlet cavity 3 is a circular cavity arranged in the middle of the valve body 1, the water inlet cavity 2 is an annular cavity surrounding the water outlet cavity 3, and in combination with fig. 1, the water inlet cavity 2 and the water outlet cavity 3 are open cavities in the valve body 1, and the two cavities are mutually sealed through a sealing component 7.
Fig. 4 is a schematic structural diagram of the valve body 1 after being partially cut in this embodiment, two buffer chambers 4 are disposed in the valve body 1, and the buffer chambers 4 are symmetrically disposed at two sides of the water outlet chamber 3. The water inlet 21 and the water outlet 31 are on the same axis, and the axial directions of the two buffer cavities 4 are mutually perpendicular to the axis of the water inlet 21 and the water outlet 31. The common cavity wall of the buffer cavity 4 and the water inlet cavity 2 is provided with a pinhole 41 for water to flow through, the pinhole 41 connects the water inlet cavity 2 with the buffer cavity 4, and the two buffer cavities 4 are communicated with the middle water outlet cavity 3. In addition, the water outlet 31 is communicated with the water outlet cavity 3 positioned in the middle of the valve body 1 through the connecting cavity 32, and in order to ensure the whole volume of the valve body 1, the two buffer cavities 4 and the connecting cavity 32 are both protruded in the water inlet cavity 2, and at the moment, the cavity of the water inlet cavity 2 is a concave-convex continuous cavity.
Fig. 2 is an enlarged view of fig. 1 a, showing the structure of the pinhole 41 and the capillary 5. In this embodiment, the same wall of the connecting cavity 32 and the water inlet cavity 2 is provided with a pinhole 41, and the capillary 5 is inserted into the pinhole 41 to introduce the water flow in the water inlet cavity 2 into the connecting cavity 32 or the buffer cavity 4. The capillary 5 has a pressure reducing effect, and the diameter of the capillary 5 in this embodiment is larger than the inner diameter of the waste water hole with the same flow rate. According to the relation between the flow rate, the sectional area and the flow velocity, the larger the sectional area is, the slower the flow velocity is, and the noise reduction effect can be achieved for the same flow rate. And the capillary 5 has a certain length, and the longer the capillary 5 tube length is, the better the depressurization effect inside the tube is.
In order to facilitate the insertion and replacement of the capillary tube 5, the side of the needle hole 41 communicating with the water inlet cavity 2 is provided with a chamfer. In this embodiment, a baffle plate 6 is disposed in the upstream direction of each buffer chamber 4, the bottom of the baffle plate 6 contacts with the bottom of the chamber of the water inlet chamber 2, a certain gap is left between the top of the baffle plate 6 and the sealing component 7, one end of the capillary tube 5 is inserted into the pinhole 41 and is located in the buffer chamber 4, and the other end of the capillary tube 5 is located in the water inlet chamber 2 on the side of the flow-facing surface of the baffle plate 6 through the gap between the baffle plate 6 and the sealing component 7.
Fig. 5 is a bottom view of the valve body 1, and the flow of water in the valve body 1 and the noise reduction principle are described with reference to fig. 5, wherein arrows in the diagram are the flow direction of water. When the electromagnetic valve is closed to discharge the waste water, the waste water with high water pressure flows into the water inlet cavity 2 from the water inlet 21, impacts on the flow baffle 6 to reduce the water pressure, and then flows into the buffer cavity 4 through the buffer of the capillary 5 in the water inlet cavity 2. After the wastewater flows into each buffer cavity 4 through each capillary 5, the wastewater flows out of the wastewater outlet cavity 3 and flows into the water outlet cavity 3. When the electromagnetic valve is opened, the sealing assembly 7 is lifted upwards, and the water inlet cavity 2 and the water outlet cavity 3 are communicated with each other. At this time, the waste water solenoid valve in this embodiment works with a normal water inlet solenoid valve, and water flows into the water inlet chamber 2 from the water inlet 21, and flows into the water outlet chamber 3 after impacting on the flow baffle 6, and finally flows out from the water outlet 31.
