[0038] This utility model proposes an electromagnetic valve.

[0039] Please refer to Figures 1 to 3 In one embodiment of this utility model, the solenoid valve includes:

[0040] Valve body 100, the valve body 100 is provided with valve cavity 130 and a first channel 122 communicating with valve cavity 130 and valve port 127, a movable piston 150 is provided in valve cavity 130, the piston 150 is used to open and close valve port 127, and a first connecting part 123 is also provided outside valve port 127; and

[0041] The connecting seat 200 is provided with a second channel 220 and a second connecting part 210. The second connecting part 210 and the first connecting part 123 are detachably connected. The second channel 220 is connected to the valve port 127.

[0042] The technical solution of this utility model involves providing a first channel 122 and a valve port 127 on the valve body 100. The first channel 122 is connected to the valve cavity 130 of the valve body 100, and the valve port 127 is also connected to the valve cavity 130 of the valve body 100. The first channel 122 connects the valve cavity 130 and the valve port 127, and the second channel 220 of the connecting seat 200 is connected to the valve port 127. The piston 150 in the valve cavity 130 controls the opening and closing of the valve port 127, realizing the on / off state of the solenoid valve. The first connecting part 123 on the valve body 100, located outside the valve port 127, and the second connecting part 210 on the connecting seat 200 are detachably connected, allowing for the replacement of the connecting seat 200 connected to the valve body 100. By selecting connecting seats 200 with different diameters of the second channel 220 and connecting the second connecting part 210 to the first connecting part 123, the second channel 220 is connected to the valve port 127, thereby changing the diameter of the solenoid valve. Figure 9As shown, the solenoid valve has an integral housing. When different diameter solenoid valves are required, the entire solenoid valve can be replaced by replacing or setting a connection seat 200 with a second channel 220 of a different diameter. This improves installation and maintenance efficiency, enhances the flexibility of the solenoid valve in adapting to fluid systems, and reduces costs.

[0043] It should be noted that the first connecting part 123 and the second connecting part 210 are detachably connected by means of snap-fit, plug-in, screw-in, interference fit, etc. The second channel 220 is formed in the connecting seat 200 and passes through the connecting seat 200. The second channel 220 can also pass through the second connecting part 210 and then connect to the valve port 127, so that the first connecting part 123 and the second connecting part 210 are arranged in a ring. The second channel 220 and the valve port 127 are formed on the inner circumference of this ring. In addition, the valve port 127 is provided in the valve body 100. A channel cylinder is formed by a protrusion on the side wall of the valve cavity 130 near the first connecting part 123. The valve port 127 is provided at the free end of the channel cylinder and is opposite to the piston 150. The first connecting part 123 is located at the end of the channel cylinder away from the valve port 127. After the first connecting part 123 and the second connecting part 210 are connected, the channel cylinder and the second channel 220 are connected, so that the valve port 127 is connected to the second channel 220. Thus, the valve port 127 is located within the valve cavity 130, and the piston 150 has good coaxiality with the valve port 127 when closing the valve port 127, thereby ensuring the sealing performance of the piston 150 when closing the valve port 127. It can be understood that the first channel 122 is located on the cavity wall of the valve cavity 130 where the valve port 127 is located, placing the first channel 122 on the side wall of the valve body 100. The valve port 127 is connected to the second channel 220, allowing the valve cavity 130 to communicate with the outside. The piston 150 controls the opening and closing state of the passage formed by the connection between the first channel 122 and the second channel 220 within the valve cavity 130.

[0044] In one embodiment, please refer to Figure 1 and Figure 8 The connecting seat 200 forms a second channel 220. The inner diameter of the valve port 127 is H1, and the diameter of the second channel 220 is H2, satisfying: H1 ≤ H2. It can be understood that the diameter of the second channel 220 is greater than or equal to the inner diameter of the valve port 127, indicating that the solenoid valve has a larger diameter. This reduces resistance and energy loss caused by the abrupt change in the size of the second channel 220, lowers flow resistance to improve the flow capacity of the second channel 220, and allows the fluid to flow more efficiently within the solenoid valve, achieving large flow channel switching. In another embodiment, please refer to... Figure 7H1 > H2. When the solenoid valve is open, as fluid flows out of valve port 127 and into the second channel 220, the sudden reduction in the size of the second channel 220 increases the fluid velocity, thus enabling further control and regulation of the fluid flow rate. Simultaneously, it can also increase the fluid pressure to meet current operating requirements.

[0045] In one embodiment, please refer to Figure 1 and Figure 2 The second connecting portion 210 is inserted into the first connecting portion 123, and the outer periphery of the second connecting portion 210 and the inner periphery of the first connecting portion 123 are sealed together. Without loss of generality, for the connecting seats 200 of different diameter second channels 220, the first connecting portion 123 and the second connecting portion 210 are a standardized connection configuration. In this embodiment, the first connecting portion 123 and the second connecting portion 210 are connected by an insertion method, ensuring the connection stability between the connecting seat 200 and the valve body 100. This also facilitates the disassembly of the first connecting portion 123 and the second connecting portion 210, improving the convenience of replacing the connecting seat 200. Furthermore, the outer diameter of the second connecting portion 210 and the inner diameter of the first connecting portion 123 are tightly abutted, effectively preventing fluid leakage at the connection point of the first connecting portion 123 and the second connecting portion 210, ensuring the normal operation of the solenoid valve. Of course, in other embodiments, the first connecting portion 123 can also be inserted into the second connecting portion 210, with the inner periphery of the second connecting portion 210 and the outer periphery of the first connecting portion 123 sealing together.

[0046] Furthermore, in this embodiment, please refer to Figure 2 and Figure 5 The inner diameter of the first connecting part 123 is H3, and the inner diameter of the valve port 127 is H1, satisfying H1>H3. It can be understood that the larger inner diameter of the first connecting part 123 allows the second connecting part 210, when inserted into the inner circumference of the first connecting part 123, to meet the needs of the second channel 220 with different diameters for regulating fluid flow rate. This provides design space for the diameter H2 of the second channel 220 to be larger than the diameter H1 of the valve port 127, ensuring the effectiveness of changing the diameter of the solenoid valve port 127 by replacing the connecting seat 200. Simultaneously, H1 being larger than H3 also facilitates the insertion and connection of the second connecting part 210 into the first connecting part 123. Of course, in other embodiments, when the first connecting part 123 is inserted into the second connecting part 210, H3 may be less than or equal to H1. Alternatively, the second channel 220 may have two flow sections, corresponding to the second connecting part 210 and other parts of the connecting seat 200 respectively. The second channel 220 adjusts the diameter of the flow section of the corresponding connecting seat 200 excluding the second connecting part 210 to achieve adjustment of different diameters of the solenoid valve.

[0047] In one embodiment, please refer to Figure 2 , Figure 5 and Figure 6A first flared inclined wall 126 is provided at one end of the valve port 127 corresponding to the first connecting portion 123, and a second flared inclined wall 230 is provided at one end of the second channel 220 corresponding to the second connecting portion 210. The first flared inclined wall 126 and the second flared inclined wall 230 are axially opposite each other along the valve body 100. It can be understood that the first flared inclined wall 126 is arc-shaped, and its diameter gradually increases in the direction from the valve port 127 towards the connecting seat 200. Correspondingly, the second flared inclined wall 230 is also arc-shaped, and its diameter gradually increases in the direction from the connecting seat 200 towards the valve port 127. Thus, when the fluid passes through the valve port 127 and the second channel 220, it can flow more smoothly, reducing fluid resistance and energy loss. When the fluid flow rate is large or the flow velocity is high, the first flared inclined wall 126 and the second flared inclined wall 230 can effectively avoid turbulence and eddies, improving fluid transport efficiency. Meanwhile, the relative arrangement of the first flared inclined wall 126 and the second flared inclined wall 230 can prevent interference between the valve body 100 and the connecting seat 200 during installation, thus avoiding misalignment between the second channel 220 and the valve port 127. This makes the connection between the connecting seat 200 and the valve body 100 more convenient and accurate. Of course, in other embodiments, flared inclined walls can also be provided on the inner periphery of the first connecting portion 123 and the second connecting portion 210, while a constricted inclined wall is provided on the outer periphery of the other. The flared inclined wall is radially adapted to abut against the constricted inclined wall, ensuring smooth flow of fluid at the junction of the second channel 220 and the valve port 127.

[0048] In one embodiment, please refer to Figure 2 , Figure 5 and Figure 6The first connecting part 123 has a first outer wall 124 on its outer periphery, and the connecting seat 200 has a second outer wall 211 on its outer periphery. The diameter of the first outer wall 124 is D1, and the diameter of the second outer wall 211 is D2, satisfying D2≥D1. It should be noted that after the first connecting part 123 and the second connecting part 210 are connected, sealing measures will be added to the outer periphery of the connection gap between the connecting seat 200 and the valve body 100, such as filling with sealant or adding molten material. These measures can easily increase the diameter of the first outer wall 124, limiting D2≥D1. The outer periphery diameter of the connecting seat 200 is relatively large. After the connecting seat 200 and the valve body 100 are sealed together, it can ensure that the outer periphery of the first connecting part 123 of the connecting seat 200 and the valve body 100 is flat and consistent. This reduces interference between the connection point of the valve body 100 and the connecting seat 200 and the interior of the external pipeline when the connecting seat 200 is connected to the external pipeline, ensuring the connection stability and operational convenience of the solenoid valve and the external pipeline. Meanwhile, when the second channel 220 is connected to the external pipe, the diameter of the second outer wall 211 is greater than or equal to the diameter of the first outer wall 124. This avoids interference between the external pipe and the first connecting part 123, thereby reducing interference with the connection between the connecting seat 200 and the valve body 100 and ensuring the connection stability of the first connecting part 123 and the second connecting part 210. Of course, in other embodiments, depending on the different connection methods between the second channel 220 and the external pipe, the diameter of the second outer wall 211 may also be smaller than the diameter of the first outer wall 124.

[0049] Furthermore, in this embodiment, please refer to Figure 2 , Figure 5 and Figure 6The outer periphery of the connecting seat 200 is also provided with a third outer wall 212. The second outer wall 211 and the third outer wall 212 are distributed sequentially along the axial direction of the second channel 220. The second outer wall 211 is located adjacent to the second connecting part 210. The diameter of the third outer wall 212 is D3, which satisfies: D3>D2. It should be noted that after the first connecting part 123 and the second connecting part 210 are connected, sealing measures will be added to the outer periphery of the connection gap between the connecting seat 200 and the valve body 100, such as filling with sealant and adding molten material. These measures can easily increase the diameter of the first outer wall 124 and the second outer wall 211, limiting D3 to D2. The diameter of the third outer wall 212 is relatively large. After the connecting seat 200 and the valve body 100 are sealed together, it can ensure that the outer periphery of the first connecting part 123 of the connecting seat 200 and the valve body 100 is as flat and consistent as possible. This reduces the interference between the connection point of the valve body 100 and the connecting seat 200 and the interior of the external pipe when the connecting seat 200 is connected to the external pipe, thus ensuring the connection stability and ease of operation of the solenoid valve and the external pipe. Meanwhile, when the second channel 220 is connected to the external pipe, the diameter of the third outer wall 212 is larger than the diameter of the second outer wall 211, and the diameter of the second outer wall 211 is greater than or equal to the diameter of the first outer wall 124. That is, the diameter of the third outer wall 212 is also larger than the diameter of the first outer wall 124, thereby avoiding interference between the external pipe and the first connecting part 123, reducing interference with the connection between the connecting seat 200 and the valve body 100, and ensuring the connection stability of the first connecting part 123 and the second connecting part 210. Of course, in other embodiments, depending on the different connection methods between the second channel 220 and the external pipe, the diameter of the third outer wall 212 may also be smaller than the diameter of the second outer wall 211.

[0050] In one embodiment, please refer to Figure 2 , Figure 3 and Figure 5The valve body 100 has a fourth outer wall 125 on its outer periphery, which is located adjacent to the first connecting part 123. The diameter of the fourth outer wall 125 is D4, satisfying D4>D2. It can be understood that a stepped surface is formed between the fourth outer wall 125 and the first outer wall 124, and the stepped surface faces the connecting seat 200. The stepped surface can serve as a positioning reference when connecting the connecting seat 200 to the external pipeline, thereby quickly and accurately inserting the connecting seat 200 into the external pipeline, reducing the time spent on trial and error during the connection process, and thus reducing the friction between the external pipeline and the outer periphery of the connecting seat 200, especially reducing the frictional force pulling the connecting seat 200 away from the valve body 100, thereby avoiding any impact on the connection stability and sealing performance of the connecting seat 200 and the valve body 100. Of course, in other embodiments, a protrusion may be provided on the outer periphery of the valve body 100 to provide a positioning reference for the connection between the second channel 220 and the external pipeline, thereby ensuring the convenience of the connection operation between the solenoid valve and the external pipeline and ensuring the sealing of the connection between the valve body 100 and the connecting seat 200.

[0051] In one embodiment, please refer to Figure 1 , Figure 6 and Figure 7 The solenoid valve also includes a first sealing ring 250. A first groove 240 is provided on the outer periphery of the connecting seat 200. The first sealing ring 250 is fitted into the first groove 240, which is located further away from the valve port 127 than the second connecting portion 210. The first sealing ring 250 is installed within the first groove 240. When the connecting seat 200 is connected to an external pipe, the first sealing ring 250 is compressed and deformed, filling the gap between the connecting seat 200 and the external pipe. This effectively prevents fluid from seeping through the connection gap between the first connecting portion 123 and the second connecting portion 210, ensuring the sealing performance of the fluid control system in which the solenoid valve is located. Simultaneously, positioning the first groove 240 further away from the valve port 127 than the second connecting portion 210 allows the first sealing ring 250 to be in a more suitable sealing position after the connecting seat 200 is inserted into the external pipe. This avoids affecting the sealing effect due to different insertion depths of the connecting seat 200 or changes in the size of the external pipe, thus improving the reliability of the seal. In addition, the first groove 240 is provided on the connecting seat 200, which facilitates the forming of the first groove 240 and ensures the installation stability of the first sealing ring 250. In another embodiment, please refer to... Figure 8 The outer periphery of the connecting seat 200 and the outer periphery of the first connecting part 123 form a first groove 240. The first sealing ring 250 is adapted to be installed in the first groove 240, and the first groove 240 is farther away from the valve port 127 than the second connecting part 210, so as to ensure the sealing of the fluid system in which the solenoid valve is located and reduce the molding difficulty of the connecting seat 200.

[0052] In one embodiment, please refer to Figure 3 and Figure 4The valve body 100 includes a valve cover 110 and a connector 120. The connector 120 and the valve cover 110 enclose a valve cavity 130. A first channel 122 is disposed on the side wall of the valve cover 110 or the connector 120. A valve port 127 is disposed on the connector 120. A first connecting portion 123 is disposed at the end of the connector 120 away from the valve cover 110. It can be understood that dividing the valve body 100 into a valve cover 110 and a connector 120, with the valve cover 110 and the connector 120 together enclosing the valve cavity 130, facilitates the installation of components such as the piston 150 within the valve cavity 130. It also ensures the forming quality of the valve port 127 within the valve cavity 130, improves the stability of the solenoid valve, and reduces the manufacturing difficulty of the solenoid valve. The first channel 122 is located on the side of the connector 120 or valve cover 110, and the valve port 127 is located on the connector 120. This ensures the coaxiality of the piston 150 opening and closing the valve port 127, while also providing a path for fluid to enter or leave the valve chamber 130. If the connector 120 or valve cover 110 has multiple first channels 122 on its peripheral sidewall, different positions of the first channels 122 can be selected according to different application scenarios and space constraints, improving the flexibility of the overall layout of the valve body 100. Of course, in other embodiments, the valve body 100 can also be split in half axially and radially merged to enclose the valve chamber 130.

[0053] Furthermore, in this embodiment, please refer to Figure 1 , Figure 3 and Figure 4 The solenoid valve also includes a second sealing ring 140. A second groove 111 is provided on the outer periphery of the valve cover 110, and the second sealing ring 140 is fitted into the second groove 111. It can be understood that the second sealing ring 140 is installed in the second groove 111 of the valve cover 110. When the valve cover 110 is connected to other components, the second sealing ring 140 is compressed and deformed, filling the gap between the valve cover 110 and other components, thereby effectively preventing fluid leakage from the connection point between the valve cover 110 and other components, ensuring the sealing performance of the fluid system in which the solenoid valve is located. Without loss of generality, positioning the second groove 111 further away from the connecting seat 200 than the connecting member 120 allows the second sealing ring 140 to be in a more suitable sealing position after the valve cover 110 is connected to the external pipeline, avoiding any impact on the sealing effect due to the connection position of the valve cover 110 and the external pipeline, or changes in the size of the external pipeline, thus improving the reliability of the seal. Furthermore, the valve cover 110 is positioned within the second groove 111, facilitating the formation of the second groove 111 and ensuring the installation stability of the second sealing ring 140. Of course, in other embodiments, a second groove 111 is formed on the outer periphery of the valve cover 110 and the outer periphery of the connector 120. The second groove 111 is located further away from the connector 200 than the connector 120 to ensure the sealing of the fluid system in which the solenoid valve is located and to reduce the molding difficulty of the valve body 100.

[0054] Specifically, in this embodiment, please refer to Figure 1 , Figure 3 and Figure 4 The valve cover 110 is provided with a third connecting portion 112, and the end of the connector 120 away from the first connecting portion 123 is provided with a fourth connecting portion 121. The third connecting portion 112 and the fourth connecting portion 121 are inserted into each other, and the radial sidewalls of the third connecting portion 112 and the fourth connecting portion 121 are sealed together. It can be understood that the insertion and engagement of the third connecting portion 112 and the fourth connecting portion 121 allows the valve cover 110 and the connector 120 to be tightly connected together, forming a complete valve body 100, ensuring the sealing of the valve cavity 130 at the connection between the valve cover 110 and the connector 120. Specifically, whether the fourth connecting portion 121 is inserted into the inner circumference of the third connecting portion 112, or the third connecting portion 112 is inserted into the inner circumference of the fourth connecting portion 121, both exhibit a radial sidewall sealing engagement between the third connecting portion 112 and the fourth connecting portion 121, ensuring the sealing of the connection between the valve cover 110 and the connector 120. Meanwhile, the third connecting part 112 and the fourth connecting part 121 are interlocked. When pressure is applied to the cavity wall by the valve cavity 130, the interlocking of the third connecting part 112 and the fourth connecting part 121 further promotes the radial sealing fit between them, ensuring the stability of the valve body 100. Furthermore, when maintenance or replacement of the internal components of the valve cavity 130 is required, the interlocking fit of the third connecting part 112 and the fourth connecting part 121 allows for relatively easy separation of the valve cover 110 and the connecting part 120, reducing maintenance difficulty and cost. Of course, in other embodiments, the valve cover 110 and the connecting part 120 may be connected by welding or screwing.
