Description

Technical Field

[0001] This application relates to the field of impregnation equipment technology, and in particular to a valve device for an impregnation machine. Background Technology

[0002] When processing electronic components, inductors, and other products, impregnation machines require the impregnation solution to penetrate micropores under vacuum and pressure. In existing technologies, to precisely control the vacuum and pressure parameters of a single impregnation cylinder, a one-to-one configuration of valve mechanisms is typically used. However, when companies need to operate multiple impregnation cylinders simultaneously to improve production efficiency, multiple independent valve mechanisms must be added. This not only complicates the overall structure of the impregnation equipment but also significantly increases its footprint and overall volume, restricting workshop space planning and increasing manufacturing and maintenance costs.

[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0004] In view of at least one of the above technical problems, this application provides a valve device for an impregnation machine.

[0005] This application provides a valve device for an impregnation machine, the device comprising: The valve seat includes a first seat body and a second seat body. The first seat body has a main channel, and the second seat body has a liquid distribution channel communicating with the main channel. The second seat body also has a first branch and a second branch communicating with the liquid distribution channel respectively. Valve mechanism, the valve mechanism is located on the first body; The liquid separation mechanism includes a switching valve, a retainer, and a closing shaft. The retainer is fixed on the liquid separation channel and has a first opening and a second opening. The first opening corresponds to a first branch, and the second opening corresponds to a second branch. The switching valve is mounted on a second seat. The closing shaft is coaxially connected to the output shaft of the switching valve. The closing shaft is T-shaped and is configured to close or open the second opening under drive.

[0006] This device, through a valve mechanism paired with a second seat integrating dual branches, can correspond to two impregnation cylinders, eliminating the need for multiple independent valve mechanisms. This ultimately reduces the number of valves, lowers equipment manufacturing and maintenance costs, simplifies the overall equipment structure, and reduces the footprint and volume. Furthermore, the cage opening precisely aligns with the branches, and the T-shaped closed shaft can independently control the branch's on / off state under the drive of the switching valve, avoiding parameter fluctuations. Ultimately, this achieves a balance between the efficiency of simultaneous multi-cylinder operation and precise control of vacuum and pressure parameters in a single cylinder.

[0007] In some possible implementations, the closed shaft includes a shaft body, a sealing element, a filler, a fixing element, a first sealing ring, and a second sealing ring. The shaft body is coaxially connected to the output shaft of the switching valve. The sealing element is connected to the end of the shaft body away from the switching valve. The filler is connected to the sealing element. The fixing element is sequentially inserted into the filler, the sealing element, and the shaft body. A first receiving cavity is provided between the shaft body and the sealing element. A second receiving cavity is provided between the filler and the sealing element. The first sealing ring is placed in the first receiving cavity, and the second sealing ring is placed in the second receiving cavity.

[0008] In some possible implementations, both the first sealing ring and the second sealing ring protrude from the closure.

[0009] In some possible implementations, the horizontal cross-section of the closure is circular.

[0010] In some possible implementations, the diameter of the closure is larger than that of the second opening.

[0011] In some possible implementations, both the first and second sealing rings are T-shaped sealing rings.

[0017] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0018] like Figures 1 to 3 As shown, one embodiment provides a valve device for an impregnation machine, the device including: a valve seat 100, a valve mechanism 200 and a liquid dispensing mechanism 300.

[0019] Valve seat 100 includes a first seat body 110 and a second seat body 120. The first seat body 110 has a main channel 111, and the second seat body 120 has a liquid distribution channel 121 connected to the main channel 111. The second seat body 120 also has a first branch 122 and a second branch 123 connected to the liquid distribution channel 121 respectively.

[0020] Valve mechanism 200 is mounted on the first seat 110.

[0021] The valve mechanism 200 includes, but is not limited to, an inlet valve, a pressure valve, a return valve, a pressure relief valve, and a pressure pump provided on the first seat 110.

[0022] The liquid dispensing mechanism 300 includes a switching valve 310, a retainer 320, and a closing shaft 330. The retainer 320 is fixed on the liquid dispensing channel 121 and has a first opening 321 and a second opening 322. The first opening 321 corresponds to the first branch 122, and the second opening 322 corresponds to the second branch 123. The switching valve 310 is mounted on the second seat 120. The closing shaft 330 is coaxially connected to the output shaft of the switching valve 310. The closing shaft 330 is T-shaped and is configured to close or open the second opening 322 under drive.

[0023] In the liquid distribution mechanism 300, with the cooperation of the T-shaped closed shaft 330 and the opening of the retainer 320, the second opening 322 can be accurately closed and opened under the drive of the switching valve 310, thereby controlling the flow state of the fluid in the first branch 122 and the second branch 123, meeting the fluid distribution requirements under different working conditions of the impregnation machine, and improving the flexibility of the impregnation machine operation.

[0024] The retainer 320 is fixed on the liquid distribution channel 121, providing a stable positioning reference for the movement of the closed shaft 330, ensuring that the closed shaft 330 can accurately correspond to the opening during the switching process, reducing the liquid distribution error caused by component displacement, and ensuring the long-term stable operation of the device.

[0025] When the valve device for the impregnation machine in this embodiment is working, the fluid to be treated first enters the first seat 110 of the valve seat 100 and flows through the main channel 111 opened on the first seat 110. The main channel 111 serves as the main transport path for the fluid, providing a stable flow channel for the fluid. The valve mechanism 200, provided on the first seat 110, controls and processes the fluid flow state in the main channel 111 according to the working requirements of the impregnation machine, mainly including pressurization. The fluid flows from the main channel 111 into the distribution channel 121 of the second seat 120. The distribution channel 121 serves as a transition channel for fluid diversion, guiding the fluid to subsequent branch paths. At this time, the retainer 320 fixed on the distribution channel 121 plays a positioning role. Its first opening 321 corresponds to the first branch 122 of the second seat 120, and its second opening 322 corresponds to the second branch 123, providing a clear channel interface for fluid diversion. The switching valve 310, mounted on the second seat 120, is activated, and its output shaft drives the T-shaped closed shaft 330, which is coaxially connected to it, to move. If fluid needs to flow only through the first branch 122, the switching valve 310 drives the closed shaft 330 to move, so that the closed end of the closed shaft 330 covers and closes the opening of the second branch 123, and the fluid can only flow into the first branch 122 from the first opening 321. Conversely, if fluid needs to flow only through the second branch 123, the switching valve 310 drives the closed shaft 330 to move, so that the closed end of the closed shaft 330 covers and closes the second opening 322, and the fluid can only flow into the second branch 123 from the opening. If fluid needs to flow through both the first branch 122 and the second branch 123 simultaneously, the switching valve 310 drives the closing shaft 330 to open the second opening 322 and the opening of the second branch 123. Part of the fluid flows into the first branch 122 from the first opening 321, and the other part flows into the second branch 123 from the opening of the second branch 123, thus realizing the on-demand diversion of fluid.

[0026] This device, through a valve mechanism 200 combined with a second seat 120 integrating dual branches, can correspond to two impregnation cylinders without the need for multiple independent valve mechanisms 200. This ultimately reduces the number of valves, lowers equipment manufacturing and maintenance costs, simplifies the overall equipment structure, and reduces the footprint and volume. At the same time, the opening of the cage 320 precisely corresponds to the branch, and the T-shaped closed shaft 330 can independently control the on / off of the branch under the drive of the switching valve 310, avoiding parameter fluctuations. Ultimately, it achieves the balance between the efficiency of multi-cylinder synchronous operation and the precise control of vacuum and pressure parameters of a single cylinder.

[0027] like Figures 1 to 3 As shown, in some embodiments, the closed shaft 330 includes a shaft body 331, a sealing member 332, a filler 333, a fixing member 334, a first sealing ring 335, and a second sealing ring 336. The shaft body 331 is coaxially connected to the output shaft of the switching valve 310. The sealing member 332 is connected to the end of the shaft body 331 away from the switching valve 310. The filler 333 is connected to the sealing member 332. The fixing member 334 is sequentially inserted into the filler 333, the sealing member 332, and the shaft body 331. A first receiving cavity is provided between the shaft body 331 and the sealing member 332. A second receiving cavity is provided between the filler 333 and the sealing member 332. The first sealing ring 335 is placed in the first receiving cavity, and the second sealing ring 336 is placed in the second receiving cavity.

[0028] The shaft body 331 of the closed shaft 330 is coaxially and fixedly connected to the output shaft of the switching valve 310, ensuring that the power of the switching valve 310 is accurately transmitted to the shaft body 331. The sealing element 332 is connected to the end of the shaft body 331 away from the switching valve 310, the filler 333 is fitted into the sealing element 332, and the fixing element 334 is sequentially inserted through the filler 333, the sealing element 332 and the shaft body 331, firmly fixing the three into a whole, forming a structurally stable closed shaft 330.

[0029] A first receiving cavity is formed at the connection between the shaft 331 and the closure 332, and a first sealing ring 335 is embedded in the first receiving cavity; a second receiving cavity is formed at the connection between the filler 333 and the closure 332, and a second sealing ring 336 is embedded in the second receiving cavity. The receiving cavity positions the sealing ring to prevent the sealing ring from shifting during the operation of the device.

[0030] When the switching valve 310 drives the shaft 331 to rotate or move, the shaft 331 drives the sealing element 332 and the filling element 333 to move synchronously, thereby closing or opening the second opening 322 of the retainer 320. During fluid flow, the first sealing ring 335 tightly fits the gap between the shaft 331 and the sealing element 332, preventing fluid leakage from this gap; the second sealing ring 336 tightly fits the gap between the filling element 333 and the sealing element 332, further blocking the fluid leakage path. The double sealing structure together ensures the sealing performance of the closed shaft 330.

[0031] like Figures 1 to 3 As shown, in some embodiments, both the first sealing ring 335 and the second sealing ring 336 protrude from the closure member 332.

[0032] After the closed shaft 330 is assembled, the first sealing ring 335 and the second sealing ring 336 are respectively embedded in the corresponding first receiving cavity and second receiving cavity, and part of the sealing ring structure protrudes from the surface of the closure member 332. When the switching valve 310 drives the closed shaft 330 to move to the second opening 322 of the closed retainer 320, the first sealing ring 335 protruding from the closure member 332 will be tightly pressed and adhered to the contact surface around the opening of the retainer 320, forming a tighter sealing contact area; during fluid flow, the protruding sealing ring can more fully fill the tiny gap between the closure member 332 and the retainer 320, further blocking the fluid leakage channel.

[0033] Understandably, the sealing ring protrudes from the surface of the closure 332, changing the contact between the sealing ring and the retainer 320 from planar contact to a tight, pressing contact of the protruding part. This increases the pressure and effective contact area of ​​the sealing contact, significantly improving the sealing effect and reducing minor leaks caused by insufficient contact. Furthermore, the protruding sealing ring has a certain elastic deformation space, which can better accommodate minor gap errors between the closure 332 and the retainer 320 caused by processing or assembly, automatically compensating for the gaps and ensuring a good sealing state under different operating conditions, thus improving the adaptability and reliability of the device's sealing.

[0034] like Figures 1 to 3 As shown, in some embodiments, the horizontal cross-section of the closure 332 is circular.

[0035] like Figures 1 to 3 As shown, in some embodiments, the diameter of the closure 332 is larger than that of the second opening 322.

[0036] The diameter of the closure 332 is set to be larger than the diameter of the second opening 322 of the retainer 320. When the switching valve 310 drives the closure shaft 330 to move to the position of closing the second opening 322, the closure 332 can completely cover the entire end face of the second opening 322, and the edge of the closure 332 extends beyond the edge of the opening by a certain distance. When the fluid attempts to flow through the second opening 322, since the closure 332 completely covers the opening, the fluid cannot pass through the gap between the closure 332 and the opening, and can only be blocked on one side of the closure 332, ensuring that the second opening 322 is completely closed.

[0037] like Figures 1 to 3 As shown, in some embodiments, both the first sealing ring 335 and the second sealing ring 336 are T-shaped sealing rings.

[0038] The T-shaped structure increases the contact area between the sealing ring and the component. The transverse part fits into the receiving cavity, and the longitudinal part is squeezed against the cage 320, forming a multi-directional seal and further improving the sealing effect. In addition, the T-shaped structure has strong resistance to deformation and can maintain the sealing shape when the fluid pressure changes, reducing the risk of seal failure.

[0039] like Figures 1 to 3 As shown, in some embodiments, the outer periphery of the retainer 320 is provided with a third sealing ring and a fourth sealing ring.

[0040] like Figures 1 to 3 As shown, in some embodiments, the third and fourth sealing rings are both Tess seal rings.

[0041] The high pressure resistance, corrosion resistance, and wear resistance of the Tess seals enable them to adapt to complex working environments such as high-pressure fluids and corrosive fluids that the impregnation machine may encounter, avoiding the rapid failure of conventional seals under harsh conditions and improving the adaptability of the device to different operating environments.
