[0025] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0026] Please refer to Figure 1-10A novel fully water-cooled high-vacuum baffle valve includes a water-cooled cylinder 1 and a lower double-layer valve body 6. A flange plate 4 and a base plate 5 are provided between the water-cooled cylinder 1 and the double-layer valve body 6. The base plate 5 is integrally formed with the double-layer valve body 6. A piston rod 2 in the water-cooled cylinder 1 extends into the double-layer valve body 6 through the flange plate 4 and the base plate 5. A double-layer valve plate 35 is provided at the bottom end of the piston rod 2. A horizontally arranged double-layer air inlet pipe 7 is provided around the circumference of the double-layer valve body 6. A double-layer air outlet pipe 9 is provided at the bottom of the double-layer valve body 6. The double-layer valve plate 35 is matched with the port of the double-layer air outlet pipe 9.
[0027] During operation, high-temperature gas is injected into the double-layer valve body 6 through the double-layer outlet pipe 9. When the water-cooled cylinder 1 runs, the piston rod 2 extends and retracts. When the piston rod 2 extends, the double-layer valve plate 35 at the bottom blocks the double-layer outlet pipe 9, at which point the double-layer valve body 6 is closed, and the high-temperature gas inside cannot flow. When the piston rod 2 retracts, the double-layer valve plate 35 does not contact the double-layer outlet pipe 9, at which point the double-layer valve body 6 opens, and the internal gas can flow outward. Since the inlet pipe, outlet pipe, and valve body are all double-layered, a cavity is formed inside. The cavity contains flowing coolant to cool and lower the temperature of the high-temperature gas. That is, initial cooling at the inlet, further cooling inside the valve body, and cooling again at the outlet can greatly improve the cooling effect, avoid high-temperature damage to the valve body, and provide all-round cooling protection for the valve body, meeting the requirements for long-term operation of the valve body in high-temperature environments.
[0028] Please refer to it again. Figure 9-10 In this embodiment, the bottom surface of the flange plate 4 is provided with an annular channel 41, the port of the annular channel 41 is sealed and fitted with the substrate 5, and a graphite ultra-high temperature sealing ring is provided at the sealing and fitting point. The circumference of the flange plate 4 is provided with a channel inlet hole 42 and a channel outlet hole 43, and both the channel inlet hole 42 and the channel outlet hole 43 are connected to the annular channel 41.
[0029] When in use, both the inlet hole 42 and the outlet hole 43 of the channel are connected to the external pipe and injected with coolant. At this time, the coolant enters the annular channel 41, which can cool and reduce the temperature of the top of the double-layer valve body 6, further improving the cooling effect. In addition, since the water-cooled cylinder is located on the flange plate 4, it can also dissipate heat from the water-cooled cylinder above, making it highly practical.
[0030] Furthermore, the substrate 5 is symmetrically provided with a substrate liquid inlet hole 51 and a substrate liquid outlet hole 52 on its circumference. The double-layer valve body 6 is provided with a cooling chamber 61. The substrate liquid inlet hole 51 and the substrate liquid outlet hole 52 are both connected to the cooling chamber 61. In use, the substrate liquid inlet hole 51 and the substrate liquid outlet hole 52 are both connected to external pipelines. Coolant is injected into the substrate liquid inlet hole 51. At this time, the coolant enters the cooling chamber 61 around the double-layer valve body 6. After cooling and heat exchange, it is discharged from the substrate liquid outlet hole 52, thereby cooling down the high-temperature gas inside the double-layer valve body 6.
[0031] In this embodiment, a second cooling chamber 71 is provided inside the double-layer air intake pipe 7. A second flange plate 8 is provided at the end of the double-layer air intake pipe 7. A first liquid inlet hole 81 and a first liquid outlet hole 82 are symmetrically provided around the circumference of the second flange plate 8. Both the first liquid inlet hole 81 and the first liquid outlet hole 82 are connected to the second cooling chamber 71. Similarly, both the first liquid inlet hole 81 and the first liquid outlet hole 82 are connected to external pipelines. Coolant is injected into the first liquid inlet hole 81. At this time, the coolant enters the second cooling chamber 71 around the double-layer air intake pipe 7. After cooling and heat exchange, it is discharged from the first liquid outlet hole 82. Since the cooling chamber 71 cools down, the high-temperature gas can be initially cooled before entering the valve body.
[0032] Furthermore, the double-layer air outlet pipe 9 is provided with a cooling chamber 3 91, and the end of the double-layer air outlet pipe 9 is provided with a flange plate 3 10. The flange plate 3 10 is symmetrically provided with a liquid inlet hole 2 101 and a liquid outlet hole 2 102 around its circumference. Both the liquid inlet hole 2 101 and the liquid outlet hole 2 102 are connected to the cooling chamber 3 91. This principle is the same as that of the cooling chamber 1 61 and the cooling chamber 2 71, and will not be elaborated on here.
[0033] In other words, cooling chamber 1 (61), cooling chamber 2 (71), and cooling chamber 3 (91) all achieve coolant circulation through corresponding inlet and outlet holes, thereby cooling the high-temperature gas from multiple directions with significant effect and strong practicality.
[0034] Please refer to it again. Figure 4 and Figure 8 The piston rod 2 includes an inner cylinder 33 and an outer cylinder 34, which are coaxially arranged and do not contact each other, leaving space for coolant flow between them. The double-layer valve plate 35 is hollow and has a baffle 36. The baffle 36 has multiple return holes 37 around its circumference. The inner cylinder 33 is connected to the lower part of the baffle 36, and the outer cylinder 34 is connected to the surface of the double-layer valve plate 35. After the coolant is input into the inner cylinder 33, it passes through the baffle 36 and the return holes 37, and finally flows upward between the outer cylinder 34 and the inner cylinder 33. The specific flow direction of the coolant is as follows: Figure 8 As shown.
[0035] Additionally, the piston rod 2 is provided with an end 3 at its top, which fixes the outer cylinder 34 and the inner cylinder 33. The surface of the end 3 is provided with an end inlet hole 31, and the circumference of the end 3 is provided with an end outlet hole 32. The end inlet hole 31 is connected to the inner cylinder 33, and the end outlet hole 32 is connected to the gap between the inner cylinder 33 and the outer cylinder 34. That is to say, the coolant is injected into the inner cylinder 33 at the end inlet hole 31 and then flows into the lower part of the partition 36. As the coolant is continuously injected and the liquid level rises, the coolant will overflow the surface of the partition at the return hole 37. Finally, the coolant flows upward between the outer cylinder 34 and the inner cylinder 33 and is discharged at the end outlet hole 32, thereby realizing circulation.
[0036] As the water-cooled cylinder moves continuously, the double-layer valve plate 35 rises and falls continuously, allowing it to come into contact with high-temperature gas at different heights. This enables cooling within the double-layer valve body, resulting in a significant improvement in cooling efficiency.
[0037] Based on the above embodiments, in order to improve the coolant circulation effect, pumps are installed on the pipes connected to the end inlet hole 31, the channel inlet hole 42, the substrate inlet hole 51, the first inlet hole 81 and the second inlet hole 101, which can accelerate the flow of coolant and improve the cooling efficiency.
[0038] Based on the above embodiments, the coolant can be cooling water, or it can be ethylene glycol-based coolant, silicone oil-based coolant, or other coolants, as long as it can achieve the cooling effect.
[0039] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
