[0039] The following reference Figures 1-9Describe the solenoid valve assembly 100 according to an embodiment of the present utility model, which has high installation reliability, is convenient for later maintenance, can reduce maintenance costs, and save installation and maintenance time.

[0040] As Figures 1-9 shown, the solenoid valve assembly 100 according to an embodiment of the present utility model includes: a mounting body 1, a valve body assembly 10, an electromagnetic drive assembly 6, a valve core assembly 7, and a connecting member 8.

[0041] The valve body assembly 10 is installed in the mounting body 1. The valve body assembly 10 defines a valve cavity 36 and a valve port 361 communicating with the valve cavity 36. The valve core assembly 7 is movably installed in the valve cavity 36. The electromagnetic drive assembly 6 is used to drive the valve core assembly 7 to move in the valve cavity 36 to selectively conduct or close the valve port 361. The connecting member 8 is detachably connected to the mounting body 1 and is used to press the valve body assembly 10 against the mounting body 1.

[0042] Among them, a solenoid valve is an industrial device controlled by electricity magnetism. It is a basic automation component for controlling fluids and belongs to an actuator. It is not limited to hydraulic and pneumatic applications. It is used in industrial control systems to adjust the direction, flow rate, speed, and other parameters of the medium. The solenoid valve can cooperate with different circuits to achieve the expected control, and both the control accuracy and flexibility can be guaranteed. It has a wide application range and high flexibility.

[0043] Specifically, the solenoid valve assembly 100 is provided with a valve body assembly 10. The valve body assembly 10 can be set as an integral structure or a split structure. And the valve body assembly 10 is set as a rotary body structure. The valve body assembly 10 internally defines a valve cavity 36, and a valve port 361 is formed in the valve cavity 36. The valve core assembly 7 can be installed in the valve cavity 36, and the valve core assembly 7 is movable relative to the valve cavity 36. Thus, the valve port 361 can be controlled to be conducted or closed by the valve core assembly 7.

[0044] Furthermore, the solenoid valve assembly 100 is also provided with an electromagnetic drive assembly 6. The electromagnetic drive assembly 6 is arranged on one side of the valve core assembly 7. And when the solenoid valve assembly 100 is powered on, the electromagnetic drive assembly 6 can generate a magnetic force, so that the electromagnetic drive assembly 6 can drive the valve core assembly 7 to move in the valve cavity 36. Thus, the valve core assembly 7 can selectively conduct or close the valve port 361. That is, when the electromagnetic drive assembly 6 is not powered on, the valve core assembly 7 closes the valve port 361. When the electromagnetic drive assembly 6 is powered on, the valve core assembly 7 conducts the valve port 361, so that the medium can flow through the solenoid valve assembly 100.

[0045] In addition, the solenoid valve assembly 100 is further provided with an installation body 1 and a connecting member 8. The valve body assembly 10 can be installed inside the installation body 1. The connecting member 8 can be made of materials such as 6061 aluminum alloy, and can also be set as a rotary body structure. The connecting member 8 can be detachably connected to the installation body 1, that is, the connecting member 8 can be connected to the installation body 1 and can also be separated from the installation body 1. After the valve body assembly 10 is installed inside the installation body 1, the connecting member 8 can be connected to the installation body 1. And during the connection process of the connecting member 8 and the installation body 1, the connecting member 8 can press the valve body assembly 10 towards the installation body 1, thereby improving the installation reliability and making the valve body 2 and the valve seat 3 detachable relative to the installation body 1, which is convenient for later maintenance.

[0046] According to the solenoid valve assembly 100 of the embodiment of the present invention, the connecting member 8 is detachably connected to the installation body 1 and is used to press the valve body assembly 10 towards the installation body 1, which is convenient for later maintenance, can reduce the maintenance cost, save the installation and maintenance time, and has high installation reliability, better use effect and wider application range.

[0047] In some embodiments, the valve body assembly 10 includes a valve body 2 and a valve seat 3. One of the valve body 2 and the valve seat 3 is provided with a first internal thread section 31 and the other is provided with a first external thread section 21. The valve body 2 and the valve seat 3 are detachably connected through the thread fit of the first internal thread section 31 and the first external thread section 21.

[0048] Specifically, the valve body assembly 10 is provided with a valve body 2 and a valve seat 3. The valve body 2 can be made of materials such as 304 stainless steel and can be set as a rotary body structure. The valve seat 3 can be made of materials such as 6061 aluminum alloy and can also be set as a rotary body structure. And one of the valve body 2 and the valve seat 3 is provided with a first external thread section 21 and the other is provided with a first internal thread section 31. That is, the valve body 2 can be provided with the first external thread section 21 and the valve seat 3 can be provided with the first internal thread section 31, or the valve body 2 can be provided with the first internal thread section 31 and the valve seat 3 can be provided with the first external thread section 21.

[0049] In this embodiment, as Figures 1-5 shown, the valve body 2 is provided with a first external thread section 21 and the valve seat 3 is provided with a first internal thread section 31, so that the valve body 2 and the valve seat 3 are detachably connected. That is, both the valve body 2 and the valve seat 3 are independent components and can be produced separately. During assembly, the valve body 2 and the valve seat 3 can be connected, and then the valve body 2 and the valve seat 3 can jointly define a valve cavity 36. Setting the valve body 2 and the valve seat 3 to be detachable is convenient for placing the valve core assembly 7 into the valve cavity 36 during installation, which is convenient for installation. And when the valve core assembly 7 fails or other situations occur, the valve body 2 and the valve seat 3 can be separated to take out the valve core assembly 7 from the valve cavity 36, which is convenient for maintenance, can reduce the maintenance cost and save the maintenance time.

[0050] Furthermore, the first external thread section 21 is disposed on the outer peripheral wall of the valve body 2 and at one end of the valve body 2 close to the valve seat 3. The first internal thread section 31 is disposed on the inner peripheral wall of the valve seat 3 and at one end of the valve seat 3 close to the valve body 2. When the valve body 2 and the valve seat 3 are connected, the first external thread section 21 can be in threaded engagement with the first internal thread section 31, thereby enabling the valve body 2 and the valve seat 3 to be fixedly connected. The installation method is simple and can ensure the connection reliability.

[0051] In addition, when it is necessary to separate the valve body 2 and the valve seat 3, the valve body 2 and the valve seat 3 can be rotated relative to each other to separate the first external thread section 21 and the first internal thread section 31. The disassembly is simple, and the first external thread section 21 can be directly formed on the valve body 2, and the first internal thread section 31 can be directly formed on the valve seat 3 without additionally arranging a connection structure, which can reduce the setting cost and improve the lightweight design of the solenoid valve assembly 100.

[0052] And after the valve body 2 and the valve seat 3 are connected and installed in the installation body 1, the connecting member 8 can be connected to the installation body 1. During the connection process of the connecting member 8 and the installation body 1, the connecting member 8 can press one of the valve body 2 and the valve seat 3 towards the other, that is, the connecting member 8 can press the valve body 2 towards the valve seat 3 or press the valve seat 3 towards the valve body 2, thereby improving the installation reliability and making the valve body 2 and the valve seat 3 detachable relative to the installation body 1, which is convenient for later maintenance.

[0053] In some embodiments, a guiding portion 22 is formed at the end of the first external thread section 21, and the guiding portion 22 extends into the first internal thread section 31 and is in clearance fit with the inner wall of the first internal thread section 31.

[0054] Specifically, the first external thread section 21 is disposed on the outer peripheral wall of the valve body 2, and the first internal thread section 31 is disposed on the inner peripheral wall of the valve seat 3, that is, one end of the valve body 2 can extend into the valve seat 3, and thus the first external thread section 21 of the valve body 2 and the first internal thread section 31 of the valve seat 3 can be in threaded engagement to connect the valve body 2 and the valve seat 3. And as Figure 1 shown, a guiding portion 22 is disposed at the end of the valve body 2 close to the valve seat 3, that is, the guiding portion 22 is formed at the end of the first external thread section 21. When the valve body 2 and the valve seat 3 are connected, the guiding portion 22 can extend into the first internal thread section 31, so that the guiding portion 22 can be in clearance fit with the inner wall of the first internal thread section 31, which can prevent the occurrence of virtual positions during thread locking and other situations, resulting in the deviation of the valve body 2 and the valve seat 3, and further resulting in problems such as seal failure after the valve body 2 and the valve seat 3 are installed in the installation body 1, ensuring the installation reliability of the valve body 2 and the valve seat 3. And the above situation also applies to the case where the first internal thread section 31 is disposed on the valve body 2 and the first external thread section 21 is disposed on the valve seat 3, etc.

[0055] In some embodiments, a first seal 4 is installed between the valve body 2 and the mounting body 1, and a second seal 5 is installed between the valve seat 3 and the mounting body 1; in the axial direction of the valve body 2 or the valve seat 3, both the first internal thread section 31 and the first external thread section 21 are located between the first seal 4 and the second seal 5.

[0056] Specifically, both the valve body 2 and the valve seat 3 are installed within the mounting body 1, and as Figure 1 shown, a first seal 4 is provided between the valve body 2 and the mounting body 1. The first seal 4 can be set as an elastic sealing ring and has a rotary body structure. As Figures 2-3 shown, a third installation groove 24 is provided on the outer peripheral wall of the valve body 2. The third installation groove 24 is arranged around the outer peripheral wall of the valve body 2 and opens outward in the radial direction of the valve body 2. The first seal 4 can be partially placed in the third installation groove 24 through the open part and partially extend outside the third installation groove 24. After the valve body 2 is installed in the mounting body 1, the first seal 4 can be sealingly pressed against the inner wall of the mounting body 1, thereby sealing the gap between the mounting body 1 and the valve body 2.

[0057] Furthermore, as Figure 1 shown, a second seal 5 is provided between the valve seat 3 and the mounting body 1. The second seal 5 can be set as an elastic sealing ring and has a rotary body structure. As Figures 4-5 shown, a fourth installation groove 35 is provided on the outer peripheral wall of the valve seat 3. The fourth installation groove 35 is arranged around the outer peripheral wall of the valve seat 3 and opens outward in the radial direction of the valve seat 3. The second seal 5 can be partially placed in the fourth installation groove 35 through the open part and partially extend outside the fourth installation groove 35. After the valve seat 3 is installed in the mounting body 1, the second seal 5 can be sealingly pressed against the inner wall of the mounting body 1, thereby sealing the gap between the mounting body 1 and the valve seat 3.

[0058] In addition, in the axial direction of the valve body 2 or the valve seat 3, when the valve body 2 and the valve seat 3 are threadedly engaged through the first internal thread section 31 and the first external thread section 21 and installed in the mounting body 1, both the first internal thread section 31 and the first external thread section 21 are located between the first seal 4 and the second seal 5, that is, the first seal 4 and the second seal 5 can seal the connection between the valve body 2 and the valve seat 3, ensuring the operating reliability of the solenoid valve assembly 100.

[0059] In some embodiments, one of the connecting member 8 and the mounting body 1 is provided with a second internal thread section 11 and the other is provided with a second external thread section 81. The connecting member 8 and the mounting body 1 are detachably connected through the threaded engagement of the second internal thread section 11 and the second external thread section 81.

[0060] Specifically, the connecting member 8 and the mounting body 1 are detachably connected, which facilitates placing structures such as the valve body 2 and the valve seat 3 inside the mounting body 1 during installation, making it convenient for installation and maintenance. It can reduce maintenance costs and save maintenance time. One of the connecting member 8 and the mounting body 1 is provided with a second external thread section 81 and the other is provided with a second internal thread section 11. That is, the connecting member 8 can be provided with the second external thread section 81 and the mounting body 1 can be provided with the second internal thread section 11, or the connecting member 8 can be provided with the second internal thread section 11 and the mounting body 1 can be provided with the second external thread section 81. In this embodiment, as Figure 1 and Figures 6-9 shown, the connecting member 8 is provided with a second external thread section 81 and the mounting body 1 is provided with a second internal thread section 11.

[0061] Furthermore, the second external thread section 81 is provided on the outer peripheral wall of the connecting member 8 and is provided at one end of the connecting member 8 close to the mounting body 1. The second internal thread section 11 is provided on the inner peripheral wall of the mounting body 1 and is located at one end of the valve seat 3 close to the valve body 2. When the connecting member 8 and the mounting body 1 are connected, the second external thread section 81 can be in threaded engagement with the second internal thread section 11, thereby enabling the connecting member 8 and the mounting body 1 to be fixedly connected. The installation method is simple and the connection reliability can be ensured.

[0062] In addition, when it is necessary to separate the connecting member 8 and the mounting body 1, the connecting member 8 and the mounting body 1 can be rotated relative to each other to separate the second external thread section 81 and the second internal thread section 11. The disassembly is simple, and the second external thread section 81 can be directly formed on the connecting member 8 and the second internal thread section 11 can be directly formed on the mounting body 1 without additionally setting a connection structure, which can reduce the setting cost and improve the lightweight design of the solenoid valve assembly 100.

[0063] In some embodiments, the outer peripheral wall of the connecting member 8 is provided with a second external thread section 81, and the inner peripheral wall of the connecting member 8 is provided with a limiting portion 82. The limiting portion 82 presses against the valve body 2 and is used to press the valve body 2 towards the valve seat 3.

[0064] Specifically, as Figure 1 and Figures 6-9 shown, the outer peripheral wall of the connecting member 8 is provided with a second external thread section 81, the mounting body 1 is provided with a second internal thread section 11, and the second external thread section 81 can be in threaded engagement with the second internal thread section 11, thereby enabling the connecting member 8 to be connected to the mounting body 1. The valve seat 3 and the valve body 2 are both installed inside the mounting body 1, and the valve seat 3 is arranged away from the connecting member 8 and the valve body 2 is arranged close to the connecting member 8, so that when the connecting member 8 is connected to the mounting body 1, the valve body 2 can be pressed towards the valve seat 3.

[0065] Furthermore, as Figures 1-3As shown, a limiting portion 82 is provided on the inner peripheral wall of the connecting member 8, and a limiting and mating portion 25 is provided on the outer peripheral wall of the valve body 2. One of the limiting portion 82 and the limiting and mating portion 25 can be set as a limiting groove, and the other can be set as a limiting protrusion. When the connecting member 8 is connected to the mounting body 1, the limiting portion 82 of the connecting member 8 can be limited and pressed against the limiting and mating portion 25 of the valve body 2, so that the valve body 2 can be pressed tightly against the valve seat 3, ensuring the installation reliability.

[0066] In some embodiments, the connecting member 8 is sleeved outside one end of the valve body 2 facing away from the valve seat 3. An anti-loosening seal 84 is further provided on the inner peripheral wall of the connecting member 8. An installation guiding surface 23 is formed at one end of the valve body 2 facing away from the valve seat 3, and the anti-loosening seal 84 is limited and pressed outside the installation guiding surface 23.

[0067] Specifically, as Figure 1 shown, both the valve seat 3 and the valve body 2 are installed in the mounting body 1, and the valve seat 3 is arranged far from the connecting member 8, and the valve body 2 is arranged close to the connecting member 8. The connecting member 8 can be connected to the mounting body 1 through thread fitting, and when the connecting member 8 is connected to the mounting body 1, it can be pressed against the limiting and mating portion 25 through the limiting portion 82, so that the valve body 2 is pressed tightly against the valve seat 3, ensuring the installation reliability. At this time, the connecting member 8 can be sleeved outside one end of the valve body 2 facing away from the valve seat 3, and an anti-loosening seal 84 is further provided on the inner peripheral wall of the connecting member 8. The anti-loosening seal 84 can be made of EPDM material and is of a rotary body structure. A fifth installation groove 83 is provided on the inner wall of the connecting member 8, and the fifth installation groove 83 opens inwards along the radial direction of the connecting member 8, so that the anti-loosening seal 84 can be pre-installed in the fifth installation groove 83.

[0068] Furthermore, as Figures 2-3 shown, the valve body 2 is provided with an installation guiding surface 23. The installation guiding surface 23 is arranged at one end of the valve body 2 facing away from the valve seat 3, and the installation guiding surface 23 is set as an inclined surface, so that the radial dimension of the valve body 2 on the side of the installation guiding surface 23 far from the valve seat 3 is smaller than the radial dimension of the valve body 2 on the side of the installation guiding surface 23 close to the valve seat 3, which is convenient for the connecting member 8 to be sleeved on the end of the valve body 2. When the connecting member 8 is sleeved on the end of the valve body 2, the anti-loosening seal 84 pre-installed in the fifth installation groove 83 can be limited and pressed outside the installation guiding surface 23, which is convenient for installation and can ensure the sealing performance of the connection between the connecting member 8 and the valve body 2, ensuring the operation reliability of the solenoid valve assembly 100.

[0069] In some embodiments, the valve seat 3 forms an inlet flow channel 32 and an outlet flow channel 33. A flow gap 34 located in the valve cavity 36 is formed between the valve core assembly 7 and the valve seat 3. The flow gap 34 communicates between the inlet flow channel 32 and the outlet flow channel 33, and the valve core assembly 7 can move relative to the valve seat 3 to conduct or close the flow gap 34.

[0070] Specifically, as Figure 1As shown, the valve body 2 and the valve seat 3 are both disposed within the mounting body 1, and the valve body 2 and the valve seat 3 are detachably connected, thereby defining a valve chamber 36. The valve seat 3 is formed with an inlet flow passage 32 and an outlet flow passage 33. The inlet flow passage 32 and the valve chamber 36 are selectively communicated, and the outlet flow passage 33 is communicated with the valve chamber 36. That is, the medium can selectively enter the valve chamber 36 from the inlet flow passage 32, and then flow out of the valve chamber 36 through the outlet flow passage 33. A flow gap 34 located within the valve chamber 36 is formed between the valve core assembly 7 and the valve seat 3. The flow gap 34 is communicated between the inlet flow passage 32 and the outlet flow passage 33. That is, the medium in the inlet flow passage 32 can flow through the flow gap 34 to the outlet flow passage 33.

[0071] Furthermore, the valve body 2 and the valve seat 3 are connected and jointly define the valve chamber 36. The valve core assembly 7 is movably installed within the valve chamber 36. That is, the valve core assembly 7 can move towards the valve seat 3 within the valve chamber 36 or away from the valve chamber 36. The valve core assembly 7 is movable relative to the valve seat 3 to open or close the flow gap 34. That is, when the valve core assembly 7 moves towards the valve seat 3 and contacts the valve seat 3, the flow gap 34 can be closed, thereby blocking the medium in the inlet flow passage 32 from flowing to the outlet flow passage 33. When the valve core assembly 7 moves away from the valve seat 3 and separates from the valve seat 3, the flow gap 34 can be opened, thereby allowing the medium in the inlet flow passage 32 to flow to the outlet flow passage 33. The outlet flow passage 33 is provided in plurality, and the plurality of outlet flow passages 33 are spaced apart in the circumferential direction of the valve seat 3. The openings of the outlet flow passages 33 extend from the side of the valve seat 3 to the bottom of the valve seat 3, forming a hollow structure, thereby increasing the flow diameter of the valve seat 3 and shortening the height of the valve seat 3, so as to shorten the overall height of the solenoid valve assembly 100, reduce the manufacturing cost, and improve the light weight and miniaturization of the solenoid valve assembly 100.

[0072] In some embodiments, the electromagnetic driving assembly 6 includes a static iron core 62 and a moving iron core 63. The moving iron core 63 is located within the valve chamber 36 and is connected to the valve core assembly 7. The static iron core 62 is adapted to drive the moving iron core 63 to drive the valve core assembly 7 to open the valve chamber 36 when powered on. A first elastic member 64 is further provided between the static iron core 62 and the moving iron core 63. The first elastic member 64 is used to apply an elastic force to the moving iron core 63 to drive the valve core assembly 7 to close the valve chamber 36. Among them, an auxiliary elastic member 9 is further provided between the valve core assembly 7 and the valve seat 3. The auxiliary elastic member 9 is used to apply an elastic force to the valve core assembly 7 to open the valve chamber 36.

[0073] Specifically, as Figure 1As shown, the solenoid valve assembly 100 is provided with an electromagnetic drive component 6. When the solenoid valve assembly 100 is energized, the electromagnetic drive component 6 can generate magnetic force, thereby enabling the electromagnetic drive component 6 to drive the valve core component 7 to move in the valve chamber 36, so that the valve core component 7 can selectively open or close the valve chamber 36, and the electromagnetic drive component 6 is provided with a static iron core 62, a moving iron core 63 and an iron core cover 61. The iron core cover 61 can be set to a circular tubular structure made of stainless steel 305, and one end of the iron core cover 61 is connected to the valve body 2 by brazing after a clearance fit, and the other end is connected to the static iron core 62 by welding after an interference fit.

[0074] Furthermore, an active cavity is formed in the core cover 61, and the moving iron core 63 can be movably installed in the active cavity. The end of the moving iron core 63 facing away from the static iron core 62 is located in the valve cavity 36 and is connected to the valve core assembly 7, and the static iron core 62 is suitable for driving the moving iron core 63 to drive the valve core assembly 7 to open the valve cavity 36 when power is turned on. That is, after the solenoid valve assembly 100 is powered on, a magnetic force is generated between the static iron core 62 and the moving iron core 63, thereby causing the moving iron core 63 to move toward the static iron core 62, so as to drive the valve core assembly 7 to move away from the valve seat 3, so that the valve cavity 36 is opened.

[0075] In addition, if Figure 1 As shown, a first elastic member 64 is arranged between the static iron core 62 and the moving iron core 63, and the first elastic member 64 can be set as a spring, etc. The static iron core 62 is provided with a first mounting groove 621, and the moving iron core 63 is provided with a second mounting groove 631. One end of the first elastic member 64 is limitedly installed in the first mounting groove 621, and the other end is limitedly installed in the second mounting groove 631. When the solenoid valve assembly 100 is powered off and the magnetic force between the static iron core 62 and the moving iron core 63 disappears, the first elastic member 64 can apply an elastic force to the moving iron core 63 to drive the valve core assembly 7 to close the valve chamber 36, thereby ensuring the operational reliability of the solenoid valve assembly 100.

[0076] And if Figure 1 As shown, an auxiliary elastic member 9 is also provided between the valve core assembly 7 and the valve seat 3. The auxiliary elastic member 9 can be set as a spring, one end of which is clamped and connected to the valve core assembly 7, and the other end is clamped and connected to the valve seat 3. When the moving iron core 63 drives the valve core assembly 7 to move toward the static iron core 62, the auxiliary elastic member 9 can apply an elastic force to the valve core assembly 7 to open the valve cavity 36, thereby ensuring the reliability of the conduction of the valve cavity 36.
