Description

Technical Field

[0001] The present invention belongs to the technical field of pressure devices, and in particular relates to a one-way piston cylinder type ultra-high temperature and high pressure device. Background Art

[0002] In fields such as physics, chemistry, materials science, and earth science, extreme experimental conditions of ultra-high temperature and high pressure are often required for experimental research, such as simulating the reaction transformation of crustal rocks or conducting compression tests on superhard materials under ultra-high temperature conditions.

[0003] The piston cylinder type ultra-high temperature and high pressure device can provide ultra-high temperature and high pressure conditions to carry out the pressure test of superhard materials under ultra-high temperature conditions; the piston cylinder type ultra-high temperature and high pressure device usually uses a tungsten carbide ring to form a pressure chamber to hold the sample; because under ultra-high temperature conditions, the inside of the tungsten carbide ring has to withstand a temperature of more than 1000 ° C. Tungsten carbide has high compressive strength but low tensile strength. External radial constraints need to be applied to it during the pressurization process to give full play to its compressive performance and avoid deformation and damage due to tensile stress; therefore, when pressurizing, external radial constraints need to be applied to the tungsten carbide. Perform a constraint. If the external temperature of tungsten carbide is too high, the components that constrain the tungsten carbide will easily deform, resulting in the inability to constrain the tungsten carbide, making the tungsten carbide easy to deform, and the excessively high temperature will also have a certain impact on external equipment. Therefore, it is necessary to cool the outside of the tungsten carbide. A reinforcement layer (reinforcement ring) is generally set on the outside of the tungsten carbide to constrain the tungsten carbide, such as a layer of tool steel or an inner layer of tool steel plus an outer layer of tool steel, to prevent the tungsten carbide from deforming. The reinforcement layer will also be cooled to reduce the temperature of the outside of the tungsten carbide.

[0004] The relevant document discloses a bidirectional piston cylinder type ultra-high temperature and high pressure device and its use method, including an upper base plate, a lower base plate, and an upper oil cylinder, a lower oil cylinder, an upper piston, a lower piston, a transformer, a pressure sensor, a heating element, an upper piston seat and a pressure chamber for holding samples, etc. arranged between the upper base plate and the lower base plate; the upper base plate and the lower base plate are both arranged horizontally and connected by multiple pull rods.

[0005] This piston cylinder type ultra-high temperature and high pressure device only connects the upper water pan and the lower water pan by opening two small holes in the inner layer of the tool steel, and uses cooling water to flow through the small holes opened in the inner layer of the tool steel to cool the inner layer of the tool steel. The contact area between the cooling water and the reinforcement layer outside the tungsten carbide is small, and the heat exchange effect is poor. Summary of the Invention

[0006] The purpose of the present invention is to provide a one-way piston cylinder type ultra-high temperature and high pressure device to solve the problem of weak cooling effect on the reinforcement ring in the prior art.

[0007] To achieve the above object, the technical solution adopted by the present invention is:

[0008] A one-way piston cylinder type ultra-high temperature and high pressure device, comprising:

[0009] A frame body, the frame body comprising a bottom plate and a top plate arranged parallel to each other, the bottom plate being fixedly connected to the top plate;

[0010] A pressure mechanism located between the bottom plate and the top plate, comprising an upper plug rod, a lower plug rod and an oil cylinder arranged in sequence from top to bottom;

[0011] A containing assembly, the containing assembly comprising a tungsten carbide ring, a reinforcement ring, and a protective ring arranged in sequence from the inside to the outside, the circular hole of the tungsten carbide ring being a pressure cavity for holding the sample, the bottom end of the upper stopper rod and the top end of the lower stopper rod both extending into the pressure cavity;

[0012] A cooling assembly includes an annular upper water tray and an annular lower water tray, wherein the annular upper water tray is arranged at the top end of the accommodating assembly, and the annular lower water tray is arranged at the bottom end of the accommodating assembly. A cooling channel is formed between the reinforcement ring and the protective ring. An annular first cavity is formed in the annular upper water tray, and the first cavity is sealed and connected to the cooling channel. An outlet pipe connected to the first cavity is provided on the annular upper water tray, and an annular second cavity is formed in the annular lower water tray, and the second cavity is sealed and connected to the cooling channel. A water inlet pipe connected to the second cavity is provided on the annular lower water tray.

[0013] The present invention provides a frame for installing a pressure mechanism, a receiving assembly, and a cooling assembly, wherein a bottom plate is provided for installing an oil cylinder, and a top plate is provided for installing an upper plug rod. The bottom plate and the top plate are fixedly connected so that the oil cylinder can press the sample against the upper plug rod through the lower plug rod, thereby achieving the purpose of applying pressure to the sample.

[0014] The present invention applies pressure to the sample through the provided pressure-applying mechanism, thereby being able to perform pressure resistance testing on the sample or to simulate a high-pressure environment for other experiments. Specifically, the provided oil cylinder can push the lower plug rod to move upward, and the sample is located between the upper plug rod and the lower plug rod. The upward-moving lower plug rod can press the sample against the upper plug rod, and the upper plug rod is fixed to the top plate, the top plate is fixed to the bottom plate, and the bottom plate is fixed to the oil cylinder. Therefore, when the lower plug rod presses the sample against the upper plug rod, the upper plug rod can remain stationary, allowing the lower plug rod to apply pressure to the sample.

[0015] The present invention provides a containing component for holding samples, wherein a tungsten carbide ring is mainly used to hold the sample. A reinforcing ring is provided on the periphery of the tungsten carbide to protect the tungsten carbide ring and prevent the tungsten carbide ring from deformation. A protective ring is provided to surround the reinforcing ring and the tungsten carbide ring to prevent the sample from splashing and injuring the user after the tungsten carbide ring and the reinforcing ring are broken.

[0016] The present invention uses a cooling component to cool the reinforcement ring, thereby achieving the purpose of cooling the reinforcement ring. Specifically, a cooling channel is set between the reinforcement ring and the protective ring, so that the periphery of the reinforcement ring can be cooled. Compared with opening two through holes in the reinforcement ring, setting a cooling channel on the periphery of the reinforcement ring can increase the contact area between the cooling water and the reinforcement ring, thereby improving the heat exchange efficiency and achieving a better cooling effect. There is no need to open a through hole on the reinforcement ring, which can reduce the damage to the structural strength of the reinforcement ring and enable the reinforcement ring to have a better ability to prevent tungsten carbide deformation. The annular upper water tray and the annular lower water tray are used to guide the cooling water in and out of the cooling channel. The first cavity opened in the annular upper water tray and the second cavity opened in the annular lower water tray are both used to accommodate cooling water. After the external cooling water enters the first cavity through the outlet pipe, it enters the cooling channel from the first cavity to cool the reinforcement ring. After entering the cooling channel, the cooling water continues to flow into the second cavity and is then discharged through the water inlet pipe.

[0017] Furthermore, a heat sink is spirally wound along the axial direction of the outer periphery of the reinforcement ring. The outer wall of the reinforcement ring, the inner wall of the protective ring and the heat sink together form the spiral cooling channel. The heat sink can enhance the heat dissipation of the reinforcement ring. The heat sink can also form a spiral cooling channel, which can greatly increase the path length of the cooling water flowing through the reinforcement ring. When the cooling water flows into the cooling channel, it flows downward in circles around the outer periphery of the reinforcement ring, and can fully contact the heat sink, thereby greatly improving the cooling effect.

[0018] Furthermore, a threaded groove cooperating with the heat sink is provided on the inner wall of the protective ring so that the inner wall of the protective ring is threadedly connected to the heat sink. The fixed connection between the protective ring and the heat sink is achieved by the provided threaded groove, making the installation of the protective ring more convenient.

[0019] Furthermore, a plurality of first cross bars and a plurality of second cross bars are provided in the cooling channel along the winding direction of the heat sink, the first cross bars and the second cross bars are arranged at intervals, and the first cross bars and the second cross bars are arranged vertically along the diameter direction of the reinforcement ring, a first flow channel is provided between the first cross bar and the protective ring, and a second flow channel is provided between the second cross bar and the reinforcement ring. The path of the cooling channel is made more tortuous by the provision of the first cross bar and the second cross bar. Specifically, by providing the first cross bar and the second cross bar, and providing the first flow channel between the first cross bar and the protective ring, and providing the second flow channel between the second cross bar and the reinforcement ring, the cooling channel forms a serpentine path on the basis of spiral winding and descending, which can increase the path of the cooling channel again and improve the cooling effect. The first cross bar and the second cross bar can be made of metal with good thermal conductivity, and the heat of the reinforcement ring can be transferred to the first cross bar and the second cross bar, thereby improving the cooling effect.

[0020] Furthermore, a heat-conducting ring is coaxially provided on the top of the tungsten carbide ring, an annular piston cavity is provided on the top surface of the heat-conducting ring, an annular piston is coaxially provided in the piston cavity, a piston rod is provided on the top of the annular piston, and a rack is provided on one end of the piston rod outside the piston cavity. A valve is provided on the water outlet pipe, and a gear is coaxially provided on the valve, and the gear is meshed with the rack. The heat-conducting ring can transfer the heat from the top of the tungsten carbide ring to the piston cavity, so that the air in the piston cavity expands and pushes the annular piston upward. When the temperature of the tungsten carbide decreases, the heated and expanded air will contract, so that negative pressure is formed in the piston cavity, so that the outside atmosphere can push the annular piston downward. The annular piston is fixedly connected to the rack through the piston rod, and the rack can drive the valve to rotate through the meshing gears. The rotation of the valve can adjust the cooling water flow of the water outlet pipe. Therefore, The heat-conducting ring, annular piston, rack, gear and valve can cooperate with the tungsten carbide ring to adjust the flow of cooling water according to the temperature of the top of the tungsten carbide ring, thereby achieving the purpose of saving energy; when the tungsten carbide heats up, the tungsten carbide can heat the temperature of the air in the piston cavity, causing the air in the piston cavity to expand, pushing the annular piston to move upward, the annular piston drives the rack to move upward, the rack drives the gear to rotate, thereby driving the valve to rotate, adjusting the valve opening, increasing the flow of cooling water, thereby achieving a better cooling effect; when the tungsten carbide cools down, the temperature of the air in the piston cavity also decreases, the expanded air in the piston cavity contracts, and under the external atmospheric pressure, the annular piston moves downward, the annular piston drives the rack to move downward, the rack drives the gear to rotate in the opposite direction, thereby driving the valve to rotate in the opposite direction, adjusting the valve opening, reducing the flow of cooling water, thereby saving water resources.

[0021] Furthermore, the outer diameter of the heat-conducting ring is consistent with the outer diameter of the tungsten carbide ring, and the inner diameter of the heat-conducting ring is consistent with the inner diameter of the tungsten carbide ring. The heat at the top of the tungsten carbide ring can be better transferred to the heat-conducting ring.

[0022] Furthermore, the outer diameters of the annular upper water plate, the annular lower water plate and the protective ring are all consistent, and the inner diameters of the annular upper water plate, the annular lower water plate and the reinforcement ring are all consistent. The annular upper water plate and the annular lower water plate can also dissipate heat at both ends of the reinforcement ring.

[0023] Furthermore, a first sealing ring is provided between the annular upper water plate and the protective ring, and between the annular lower water plate and the protective ring, and a second sealing ring is provided between the annular upper water plate and the reinforcement ring, and between the annular lower water plate and the reinforcement ring. The first sealing ring can improve the sealing between the protective ring and the annular upper water plate and the annular lower water plate, and the second sealing ring can improve the sealing between the reinforcement ring and the annular upper water plate and the annular lower water plate.

[0024] Furthermore, a fixing ring is coaxially provided at the lower end of the tungsten carbide ring, and the lower plug rod passes through the fixing ring. The fixing ring is used to position the lower plug rod and limit the movement path of the lower plug rod.

[0025] Furthermore, a test bench is provided on the bottom plate, the annular drain pan is provided on the test bench, the oil cylinder is located inside the test bench, the lower plug rod passes through the test bench, and the set test bench is used to install cooling components and accommodation components.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] (1) The present invention uses a cooling assembly to cool the reinforcement ring, thereby achieving the purpose of cooling the reinforcement ring. Specifically, by setting a cooling channel between the reinforcement ring and the protective ring, the periphery of the reinforcement ring can be cooled, thereby cooling the reinforcement ring and further cooling the periphery of the tungsten carbide ring, making the tungsten carbide ring less likely to deform. Compared with opening two through holes in the reinforcement ring, setting a cooling channel on the periphery of the reinforcement ring can increase the contact area between the cooling water and the reinforcement ring, thereby improving the heat exchange efficiency and achieving a better cooling effect. In addition, there is no need to open a through hole on the reinforcement ring, which can reduce the damage to the structural strength of the reinforcement ring and enable the reinforcement ring to have a better ability to prevent tungsten carbide from deformation.

[0028] (2) The present invention can enhance the heat dissipation of the reinforcement ring by providing heat sinks. The heat sinks can also form a spiral cooling channel, which can greatly increase the path length of the cooling water flowing through the reinforcement ring. When the cooling water flows into the cooling channel, it flows downward in circles around the outer periphery of the reinforcement ring, and can fully contact the heat sink and the outer periphery of the reinforcement ring, thereby greatly improving the cooling effect.

[0029] (3) The present invention makes the path of the cooling channel more tortuous by setting the first cross bar and the second cross bar. Specifically, by setting the first cross bar and the second cross bar, and providing a first flow channel between the first cross bar and the protective ring, and providing a second flow channel between the second cross bar and the reinforcement ring, the cooling channel forms a serpentine path on the basis of spiral winding and descending, which can further increase the path of the cooling channel and improve the cooling effect. In addition, the first cross bar and the second cross bar can be made of metal material with good thermal conductivity, and the heat of the reinforcement ring can be transferred to the first cross bar and the second cross bar, thereby improving the cooling effect.

[0030] (4) The heat-conducting ring, annular piston, rack, gear and valve provided in the present invention can cooperate with the tungsten carbide ring to adjust the flow of cooling water according to the temperature of the top end of the tungsten carbide ring, thereby achieving the purpose of saving energy.

[0038] like Figure 1-3 As shown, this embodiment provides a one-way piston cylinder type ultra-high temperature and high pressure device, including: a frame 1, a pressure mechanism 2, a containing component 3 and a cooling component 4.

[0039] The frame 1 includes a bottom plate 101 and a top plate 102 which are arranged parallel to each other, and the bottom plate 101 and the top plate 102 are fixedly connected.

[0040] In this embodiment, the bottom plate 101 is horizontally arranged, and the top plate 102 is horizontally arranged directly above the bottom plate 101. The bottom plate 101 and the top plate 102 are fixedly connected by several tie rods. Preferably, the top plate 102 and the bottom plate 101 can be fixedly connected by three tie rods. The three tie rods can bring higher stability. The two ends of the tie rods are respectively passed through the bottom plate 101 and the top plate 102, and are respectively fixed to the top plate 102 and the floor by nuts.

[0041] The pressure mechanism 2 is located between the bottom plate 101 and the top plate 102 , and includes an upper plug rod 201 , a lower plug rod 202 and an oil cylinder 203 , which are sequentially arranged from top to bottom.

[0042] The containing assembly 3 includes a tungsten carbide ring 301, a reinforcement ring 302 and a protective ring 303 arranged in sequence from the inside to the outside. The circular hole of the tungsten carbide ring 301 is a pressure chamber 304 for holding the sample.

[0043] In this embodiment, the reinforcement ring 302 may be a steel ring, and the protection ring 303 may also be a steel ring.

[0044] The cooling assembly 4 includes an annular upper water tray 401 and an annular lower water tray 402. The annular upper water tray 401 is arranged at the top of the accommodating assembly 3, and the annular lower water tray 402 is arranged at the bottom of the accommodating assembly 3. A cooling channel 403 is formed between the reinforcement ring 302 and the protective ring 303. An annular first cavity 404 is formed in the annular upper water tray 401. The first cavity 404 is sealed and connected to the cooling channel 403. A water outlet pipe 405 connected to the first cavity 404 is provided on the annular upper water tray 401. An annular second cavity 406 is formed in the annular lower water tray 402. The second cavity 406 is sealed and connected to the cooling channel 403. A water inlet pipe 407 connected to the second cavity 406 is provided on the annular lower water tray 402.

[0045] In this embodiment, the annular upper water tray 401 and the annular lower water tray 402 are coaxially arranged with the reinforcement ring 302 .

[0046] In this embodiment, both the annular upper water tray 401 and the annular lower water tray 402 can be connected to the cooling channel 403 by providing annular slots.

[0047] In this embodiment, in order to realize the heating function and achieve the purpose of high temperature, a carbon tube or a graphite furnace can be set in the pressure chamber 304. By applying power to both ends of the carbon tube or the graphite furnace, the pressure chamber 304 can be heated to provide a high temperature environment.

[0048] In this embodiment, a pressure sensor may be installed on the oil cylinder 203 to detect the pressure applied by the oil cylinder 203 to the sample.

[0049] The present invention provides a frame 1 for installing a pressure mechanism 2, a receiving assembly 3 and a cooling assembly 4, wherein a bottom plate 101 is provided for installing an oil cylinder 203, and a top plate 102 is provided for installing an upper plug rod 201. The bottom plate 101 and the top plate 102 are fixedly connected so that the oil cylinder 203 can press the sample against the upper plug rod 201 through the lower plug rod 202, thereby achieving the purpose of applying pressure to the sample.

[0050] The present invention applies pressure to the sample through the provided pressure-applying mechanism 2, thereby being able to perform pressure resistance testing on the sample or to simulate a high-pressure environment for other experiments. Specifically, the provided oil cylinder 203 can push the lower plug rod 202 to move upward, and the sample is located between the upper plug rod 201 and the lower plug rod 202. The upward-moving lower plug rod 202 can press the sample against the upper plug rod 201, and the upper plug rod 201 is fixed to the top plate 102, the top plate 102 is fixed to the bottom plate 101, and the bottom plate 101 is fixed to the oil cylinder 203. Therefore, when the lower plug rod 202 presses the sample against the upper plug rod 201, the upper plug rod 201 can remain stationary, allowing the lower plug rod 202 to apply pressure to the sample.

[0051] The present invention provides a containing assembly 3 for holding samples, wherein a tungsten carbide ring 301 is mainly used to hold the sample. A reinforcing ring 302 is provided on the periphery of the tungsten carbide to protect the tungsten carbide ring 301 and prevent the tungsten carbide ring 301 from deformation. A protective ring 303 is provided to surround the reinforcing ring 302 and the tungsten carbide ring 301 to prevent the sample from splashing and injuring the user after the tungsten carbide ring 301 and the reinforcing ring 302 are broken.

[0052] The present invention provides a cooling assembly 4 for cooling the reinforcement ring 302, thereby achieving the purpose of cooling the reinforcement ring 302. Specifically, by providing a cooling channel 403 between the reinforcement ring 302 and the protective ring 303, the periphery of the reinforcement ring 302 can be cooled. Compared with opening two through holes in the reinforcement ring 302, providing a cooling channel on the periphery of the reinforcement ring 302 can increase the contact area between the cooling water and the reinforcement ring 302, thereby improving the heat exchange efficiency and achieving a better cooling effect. In addition, there is no need to open a through hole on the reinforcement ring 302, which can reduce the damage to the structural strength of the reinforcement ring 302. In order to make the reinforcement ring 302 have a better ability to prevent tungsten carbide from deforming, the annular upper water plate 401 and the annular lower water plate 402 are provided to guide cooling water in and out of the cooling channel 403. The first cavity 404 opened in the annular upper water plate 401 and the second cavity 406 opened in the annular lower water plate 402 are both used to accommodate cooling water. After the external cooling water enters the first cavity 404 through the outlet pipe 405, it enters the cooling channel 403 from the first cavity 404 to cool the reinforcement ring 302. After entering the cooling channel 403, the cooling water continues to flow into the second cavity 406 and is then discharged through the inlet pipe 407.

[0053] Furthermore, if Figure 4 As shown, the outer periphery of the reinforcement ring 302 is spirally coiled with heat sinks 5 along its axial direction. The outer wall of the reinforcement ring 302, the inner wall of the protective ring 303 and the heat sink 5 together form a spiral cooling channel 403. The heat sink 5 can enhance the heat dissipation of the reinforcement ring 302. The heat sink 5 can also form a spiral cooling channel 403, which can greatly increase the path length of the cooling water flowing through the reinforcement ring 302. When the cooling water flows into the cooling channel 403, it flows downward in circles around the outer periphery of the reinforcement ring 302, and can fully contact with the heat sink 5, thereby greatly improving the cooling effect.

[0054] In this embodiment, the heat sink 5 can be fixed to the outer peripheral wall of the reinforcement ring 302 by welding, so that the heat of the reinforcement ring 302 can be better transferred to the heat sink 5.

[0055] Furthermore, a threaded groove 6 is provided on the inner wall of the protective ring 303 to cooperate with the heat sink 5, so that the inner wall of the protective ring 303 is threadedly connected to the heat sink 5. The fixed connection between the protective ring 303 and the heat sink 5 is achieved through the provided threaded groove 6, making the installation of the protective ring 303 more convenient.

[0056] In this embodiment, in order to improve the sealing effect between the heat sink 5 and the inner wall of the protection ring 303 , a rubber layer may be provided in the thread groove 6 , for example, the rubber layer may be provided at the bottom of the thread groove 6 .

[0057] Furthermore, if Figure 5As shown, a plurality of first crosspieces 7 and a plurality of second crosspieces 8 are provided in the cooling channel 403 along the winding direction of the heat sink 5 ( Figure 1-4 The first crosspiece 7 and the second crosspiece 8 are not shown. The first crosspiece 7 and the second crosspiece 8 are arranged at intervals. The first crosspiece 7 and the second crosspiece 8 are vertically arranged along the diameter direction of the reinforcement ring 302. A first flow channel 9 is provided between the first crosspiece 7 and the protective ring 303, and a second flow channel 10 is provided between the second crosspiece 8 and the reinforcement ring 302. The first crosspiece 7 and the second crosspiece 8 make the path of the cooling channel 403 more tortuous. Specifically, by providing the first crosspiece 7 and the second crosspiece 8, and providing the first flow channel 9 between the first crosspiece 7 and the protective ring 303, and providing the second flow channel 10 between the second crosspiece 8 and the reinforcement ring 302, the cooling channel 403 forms a serpentine path on the basis of spiral winding and descending, which can further increase the path of the cooling channel 403 and improve the cooling effect. In addition, the first crosspiece 7 and the second crosspiece 8 can be made of metal with good thermal conductivity. The heat of the reinforcement ring 302 can be transferred to the first crosspiece 7 and the second crosspiece 8, thereby improving the cooling effect.

[0058] In this embodiment, the first crosspiece 7 and the second crosspiece 8 can be fixedly connected to the heat sink 5 by welding, so that the heat on the reinforcement ring 302 is transferred to the first crosspiece 7 and the second crosspiece 8 through the heat sink 5 .

[0059] Furthermore, a heat conducting ring 11 is coaxially provided on the top of the tungsten carbide ring 301. An annular piston cavity 12 is provided on the top surface of the heat conducting ring 11. An annular piston 13 is coaxially provided in the piston cavity 12. A piston rod 14 is provided on the top of the annular piston 13. A rack 15 is provided on the end of the piston rod 14 outside the piston cavity 12. A valve 16 is provided on the water outlet pipe 405. A gear 17 is coaxially provided on the valve 16. The gear 17 is meshed with the rack 15. The heat conducting ring 11 can be used to dissipate the heat from the top of the tungsten carbide ring 301. The air in the piston cavity 12 is transferred to the piston cavity 12, causing the air in the piston cavity 12 to expand and push the annular piston 13 upward. When the temperature of the tungsten carbide decreases, the air expanded by the heat will contract, forming a negative pressure in the piston cavity 12, so that the outside atmosphere can push the annular piston 13 downward. The annular piston 13 is fixedly connected to the rack 15 through the piston rod 14, and the rack 15 can drive the valve 16 to rotate through the meshing gear 17. The rotation of the valve 16 can adjust the cooling water flow of the outlet pipe 405. Therefore, by setting The heat-conducting ring 11, annular piston 13, rack 15, gear 17 and valve 16 can cooperate with the tungsten carbide ring 301 to adjust the flow of cooling water according to the temperature of the top of the tungsten carbide ring 301, thereby achieving the purpose of saving energy; when the tungsten carbide heats up, the tungsten carbide can heat the temperature of the air in the piston chamber 12, causing the air in the piston chamber 12 to expand, pushing the annular piston 13 to move upward, the annular piston 13 drives the rack 15 to move upward, the rack 15 drives the gear 17 to rotate, thereby driving the valve 16 to rotate, adjusting the opening of the valve 16, and increasing the flow of cooling water, thereby achieving a better cooling effect; when the tungsten carbide cools down, the temperature of the air in the piston chamber 12 also decreases, and the expanded air in the piston chamber 12 contracts. Under the external atmospheric pressure, the annular piston 13 moves downward, the annular piston 13 drives the rack 15 to move downward, the rack 15 drives the gear 17 to rotate in the opposite direction, thereby driving the valve 16 to rotate in the opposite direction, adjusting the opening of the valve 16, and reducing the flow of cooling water, thereby saving water resources.

[0060] In this embodiment, an appropriate amount of pure water can be added to the piston chamber 12 and the pure water can be heated by tungsten carbide. When the pure water changes from liquid to water vapor, its volume expands greatly, which can better drive the annular piston 13 to move.

[0061] Furthermore, the outer diameter of the heat conducting ring 11 is consistent with the outer diameter of the tungsten carbide ring 301 , and the inner diameter of the heat conducting ring 11 is consistent with the inner diameter of the tungsten carbide ring 301 , so that the heat at the top of the tungsten carbide ring 301 can be better transferred to the heat conducting ring 11 .

[0062] In this embodiment, the bottom end of the heat conducting ring 11 directly contacts the top end of the tungsten carbide ring 301 , so that the heat of the tungsten carbide ring 301 is easily transferred to the heat conducting ring 11 .

[0063] In this embodiment, a heat insulating layer may be provided on the outer periphery of the heat conducting ring 11 to reduce the influence of the cooling water in the annular upper water tray 401 on the heat conducting ring 11 .

[0064] Furthermore, the outer diameters of the annular upper water plate 401, the annular lower water plate 402 and the protective ring 303 are all consistent, and the inner diameters of the annular upper water plate 401, the annular lower water plate 402 and the reinforcement ring 302 are all consistent. The annular upper water plate 401 and the annular lower water plate 402 can also dissipate heat at both ends of the reinforcement ring 302.

[0065] Furthermore, a first sealing ring 18 is provided between the annular upper water plate 401 and the protective ring 303, and between the annular lower water plate 402 and the protective ring 303, and a second sealing ring 19 is provided between the annular upper water plate 401 and the reinforcement ring 302, and between the annular lower water plate 402 and the reinforcement ring 302. The first sealing ring 18 can improve the sealing between the protective ring 303 and the annular upper water plate 401 and the annular lower water plate 402, and the second sealing ring 19 can improve the sealing between the reinforcement ring 302 and the annular upper water plate 401 and the annular lower water plate 402.

[0066] Furthermore, a fixing ring 20 is coaxially provided at the lower end of the tungsten carbide ring 301 , and the lower plug rod 202 passes through the fixing ring 20 . The fixing ring 20 is used to position the lower plug rod 202 and limit the movement path of the lower plug rod 202 .

[0067] Furthermore, a test bench 21 is provided on the bottom plate 101, an annular drain pan 402 is provided on the test bench 21, the oil cylinder 203 is located inside the test bench 21, and the lower plug rod 202 passes through the test bench 21. The set test bench 21 is used to install the cooling component 4 and the accommodation component 3.

[0068] In this embodiment, the experimental table 21 may include a cabinet and a table top, the annular drain pan 402 is arranged on the table top, the fixing ring 20 is also arranged on the table top, the oil cylinder 203 is arranged in the cabinet, and the table top is arranged on the top of the cabinet.

[0069] In this embodiment, the fixing ring 20 is fixedly mounted on the experimental table 21 .

[0070] In this embodiment, a circle of protruding first fixing portions 22 can be provided on the upper plug rod 201. The first fixing portions 22 are used to press downward against the top of the heat-conducting ring 11, so that the heat-conducting ring 11 is pressed against the tungsten carbide ring 301, and the tungsten carbide ring 301 is pressed against the fixing ring 20. Specifically, the height of the top plate 102 can be adjusted so that the first fixing portions 22 are pressed against the top of the heat-conducting ring 11. Since the top plate 102 is fixedly connected to the bottom plate 101 by nuts and tie rods, the height of the top plate 102 can be adjusted by the nuts.

[0071] In this embodiment, the outer periphery of the heat-conducting ring 11 can also protrude to form a ring-shaped second fixing portion 23, and the second fixing portion 23 is used to press downward against the top of the annular upper water tray 401, thereby pressing the annular upper water tray 401 against the reinforcement ring 302 and the protective ring 303, and the reinforcement ring 302 and the protective ring 303 are pressed against the annular lower water tray 402, so that the annular upper water tray 401, the reinforcement ring 302, the protective ring 303 and the annular lower water tray 402 are tightly connected.

[0072] In this embodiment, the outer diameters of the first fixing portion 22 and the second fixing portion 23 are not limited. In order to better press the annular upper water plate 401 against the annular lower water plate 402, the diameters of the first fixing portion 22 and the second fixing portion 23 can be appropriately increased. When the first fixing portion 22 blocks the piston rod 14, a through hole can be opened on the first fixing portion 22 so that the piston rod 14 can pass through the first fixing portion 22; when the second fixing portion 23 blocks the water outlet pipe 405, a through hole can be opened on the second fixing portion 23 so that the water outlet pipe 405 can pass through the second fixing portion 23.

[0073] It should be noted that although the present invention is disclosed above with specific embodiments, the above embodiments are not intended to limit the present invention. Ordinary technicians in this field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined by the claims.
