[0031] The hydrophobic device 100 according to an embodiment of the present utility model will be described below with reference to the drawings.

[0032] Refer to Figure 1 As shown, the hydrophobic device 100 according to an embodiment of the present utility model is used for a steam pipeline, and the hydrophobic device 100 may include a device main body 10.

[0033] Specifically, the device main body 10 has a receiving cavity 11, an inlet 111 and an outlet 112 that communicate with the receiving cavity 11. The inlet 111 communicates the receiving cavity 11 with the end of the steam pipeline, enabling steam, liquid, etc. in the steam pipeline to enter the receiving cavity 11 through the inlet 111 and leave the receiving cavity 11 through the outlet 112. Here, the steam may be water vapor or other steam, and the liquid may be condensed water or other liquid. For the convenience of understanding, the following description takes steam as water vapor and liquid as condensed water as an example.

[0034] In some embodiments, the outlet 112 may communicate with a water storage tank to drain the condensed water in the receiving cavity 11 into the water storage tank for storing the condensed water. The outlet 112 may also directly communicate with a sewer to directly drain the condensed water into the sewer. The outlet 112 may also be connected to other components to drain the condensed water in the receiving cavity 11.

[0035] The hydrophobic device 100 further includes a heat exchange tube 20 and a heat dissipation member 30. The heat exchange tube 20 is connected to the device main body 10. The heat exchange tube 20 includes a first pipe section 21 and a second pipe section 22. The first pipe section 21 is disposed in the accommodation cavity 11 and the second pipe section 22 extends out of the accommodation cavity 11. For example, in some embodiments, an opening may be formed in the device main body 10 to allow the heat exchange tube 20 to pass through the opening, or the device main body 10 may be formed around the heat exchange tube 20, etc. The device main body 10 may be connected to the first pipe section 21, or may be connected to the second pipe section 22, or may be connected to both the first pipe section 21 and the second pipe section 22 at the same time. The connection manner between the device main body 10 and the heat exchange tube 20 may be one or a combination of connection manners such as welding, riveting, bolt connection, clamping, bonding, etc.

[0036] The heat dissipation member 30 is disposed outside the accommodation cavity 11 and is heat exchange-connected to the second pipe section 22. The heat dissipation member 30 is used for contacting and exchanging heat with the outside air so that the outside air dissipates heat from the heat exchange tube 20.

[0037] The material of the heat exchange tube 20 may be copper or aluminum with good heat conductivity, etc. The material of the heat dissipation member 30 may be copper or aluminum with good heat conductivity, etc. The connection manner between the heat exchange tube 20 and the heat dissipation member 30 may be one or a combination of manners such as welding, riveting, bolt connection, clamping, bonding, etc. The heat dissipation member 30 is heat exchange-connected to the second pipe section 22. Here, the heat exchange connection may mean that the heat dissipation member 30 is directly connected to the second pipe section 22 to conduct heat exchange by contact, or may mean that the heat dissipation member 30 is indirectly connected to the second pipe section 22 through other components or air to conduct heat exchange, as long as the heat dissipation member 30 is connected to the second pipe section 22 and can conduct heat exchange.

[0038] In some embodiments, the device main body 10, the heat exchange tube 20, and the heat dissipation member 30 are connected to each other in pairs, so that the heat dissipation member 30 and the heat exchange tube 20 are not easily separated, which is beneficial to improving the connection firmness between the heat dissipation member 30 and the heat exchange tube 20.

[0039] The heat dissipation member 30 is disposed outside the accommodation cavity 11. For example, the heat dissipation member 30 is disposed on one side of the device main body 10 (such as Figure 1 the lower side of the device main body 10 shown), or the heat dissipation member 30 is disposed around the device main body 10, etc., so that the heat dissipation member 30 can contact and exchange heat with the air outside the accommodation cavity 11. Combining the heat exchange connection between the heat dissipation member 30 and the second pipe section 22 can enable the heat exchange tube 20 to exchange heat with the outside air, so that the outside air dissipates heat from the heat exchange tube 20.

[0040] In some related technologies, there are high-boiling solvents such as ethylene carbonate that need to be removed in the steam pipeline. For example, in the drying process of certain products, it is necessary to completely remove the high-boiling solvents. By introducing high-temperature and high-pressure steam into the steam pipeline, the inside of the steam pipeline is in a high-temperature environment where the temperature is higher than the boiling point of the high-boiling solvent, so that the high-boiling solvent in the steam pipeline vaporizes to completely remove the high-boiling solvent. After the high-temperature steam exchanges heat with the relatively low-temperature high-boiling solvent, the temperature will decrease and even condensate water will be generated. For example, the temperature of the high-temperature steam is 170-180°C, and the temperature of the condensate water is 100°C, resulting in a decrease in the temperature inside the steam pipeline, and then the high-boiling solvent cannot be completely removed. Therefore, a steam trap is installed at the end of the steam pipeline to drain the condensate water from the steam pipeline.

[0041] However, the steam trap can only drain the condensate water in the steam pipeline, and it is difficult to drain the steam in the steam pipeline whose temperature has decreased but has not yet condensed into condensate water. Moreover, the temperature of the condensate water is relatively high, making it difficult for the steam to quickly liquefy and be discharged. This causes a large amount of steam with a decreased temperature in the steam pipeline, easily leading to a decrease in the temperature inside the steam pipeline, making the temperature inside the steam pipeline lower than the boiling point of the high-boiling solvent, resulting in incomplete removal of the high-boiling solvent. Additionally, condensate water is continuously generated in the steam pipeline, causing large temperature fluctuations of the high-boiling solvent in the steam pipeline and increasing the difficulty of completely removing the high-boiling solvent.

[0042] In the present application, the hydrophobic device 100 is provided at the end of the steam pipeline. The steam and condensate water in the steam pipeline enter the accommodation chamber 11 through the inlet 111. The heat of the steam is transferred to the heat exchange tube 20 by exchanging heat with the steam entering the accommodation chamber 11 through the heat exchange tube 20. The heat of the heat exchange tube 20 is transferred to the heat dissipation member 30 by exchanging heat with the heat dissipation member 30. The heat of the heat dissipation member 30 is dissipated into the external environment by exchanging heat with the external air, so that the steam in the accommodation chamber 11 exchanges heat with the external air to achieve rapid liquefaction of the steam in the accommodation chamber 11.

[0043] After the steam liquefies, it is discharged together with the condensate water introduced into the accommodation chamber 11 through the outlet 112 to discharge the steam with a decreased temperature in the steam pipeline, slow down the cooling rate in the steam pipeline, and facilitate maintaining the high-temperature environment in the steam pipeline, so as to complete related work that requires a high-temperature environment in the steam pipeline. For example, the temperature in the steam pipeline is maintained at a sufficiently high level to completely remove the high-boiling solvent in the steam pipeline.

[0044] Moreover, the steam in the steam pipeline can flow into the accommodation chamber 11 to quickly liquefy in the accommodation chamber 11, which can reduce the condensate water in the steam pipeline and facilitate the completion of related work that requires a high-temperature environment in the steam pipeline. For example, it can reduce the temperature fluctuations of the high-boiling solvent in the steam pipeline and reduce the difficulty of completely removing the high-boiling solvent.

[0045] This application discharges the steam and condensate in the steam pipeline through the hydrophobic device 100, so that the inside of the steam pipeline is in a high-temperature environment where the temperature meets the relevant working requirements. By introducing high-temperature steam into the steam pipeline for a short time, the work can be completed, such as removing high-boiling solvents in the steam pipeline, which is beneficial to improving work efficiency. Moreover, there is no need to introduce high-temperature steam into the steam pipeline for a long time or even multiple times, which can reduce steam waste, lower working costs, and has good economy.

[0046] In addition, by continuously introducing high-temperature steam into the steam pipeline at the head end of the steam pipeline and separating the steam pipeline from the external environment through the hydrophobic device 100 at the tail end of the steam pipeline, the adverse impact of the external low-temperature environment on the high-temperature environment inside the steam pipeline can be reduced, which is beneficial to maintaining the high-temperature environment inside the steam pipeline.

[0047] According to the hydrophobic device 100 of the embodiment of the present utility model, heat exchange between the inside of the accommodation cavity 11 and the external air can be achieved through the heat exchange tube 20 and the heat dissipation member 30, so as to realize the rapid liquefaction of the steam in the accommodation cavity 11, and then quickly discharge the steam and condensate in the steam pipeline, which is beneficial to maintaining the high-temperature environment inside the steam pipeline while discharging the steam and condensate in the steam pipeline, and is convenient for completing relevant work that requires a high-temperature environment inside the steam pipeline.

[0048] In some embodiments of the present utility model, such as Figure 1 shown, the heat dissipation member 30 includes a plurality of heat dissipation fins 31 arranged at intervals along its own thickness direction, so that the contact area of each heat dissipation fin 31 with the external air is relatively large, which is beneficial to increasing the overall contact area of the heat dissipation member 30 with the external air to improve the heat dissipation efficiency of the heat dissipation member 30. The heat dissipation fin 31 is provided with through holes penetrating along its own thickness direction, and the second pipe section 22 sequentially passes through the through holes of a plurality of heat dissipation fins 31, so that the second pipe section 22 is in heat exchange connection with each heat dissipation member 31, which can improve the overall heat exchange efficiency between the heat exchange tube 20 and the heat dissipation member 30, and further improve the heat exchange efficiency between the heat exchange tube 20 and the steam in the accommodation cavity 11, accelerate the cooling rate of the steam in the accommodation cavity 11, and is beneficial to further accelerating the liquefaction rate of the steam in the accommodation cavity 11.

[0049] For example, in some specific embodiments, such as Figure 1 shown, the heat dissipation member 30 is a heat dissipation fin, and the second pipe section 22 is respectively connected to each heat dissipation fin of the heat dissipation fin.

[0050] The second pipe section 22 can be welded to the heat dissipation fin 31 after passing through the through hole, the second pipe section 22 can also be in interference fit with the through hole, and the second pipe section 22 can also be in interference fit with the through hole and welded to the heat dissipation fin 31, so that the second pipe section 22 is not easily separated from the heat dissipation fin 31, the connection is firm, and the heat exchange between the heat exchange tube 20 and the heat dissipation member 30 is more stable.

[0051] In some embodiments of the present utility model, such as Figure 1As shown, the device body 10 has a drain pipe 40 which communicates with the outlet 112, and the condensate water in the accommodation cavity 11 flows through the outlet 112 to the drain pipe 40 to be discharged from the accommodation cavity 11.

[0052] The hydrophobic device 100 further includes a stopper 50 which is spaced apart from the device body 10 and disposed around the drain pipe 40. The stopper 50, the device body 10 and the drain pipe 40 define an annular installation cavity 51. The radially outer end of the annular installation cavity 51 is open, and the heat dissipation member 30 is disposed in the annular installation cavity 51. Installing the heat dissipation member 30 in the annular installation cavity 51 can not only enable the heat dissipation member 30 to contact the outside air for heat dissipation through the open port at the radially outer end of the annular installation cavity 51, but also protect the heat dissipation member 30 through the stopper 50, the device body 10 and the drain pipe 40, reducing the possibility of the heat dissipation member 30 being directly impacted by external stones or the like and damaged, which is beneficial to protecting the heat dissipation member 30.

[0053] The heat dissipation member 30 can be annular to fit the shape of the annular installation cavity 51, or the heat dissipation member 30 can also be a combination of multiple sectors, etc. The shape of the heat dissipation member 30 can be flexibly designed or selected.

[0054] In some embodiments, as Figure 1 shown, a plurality of heat dissipation fins 31 are arranged at intervals in the up-down direction. The through holes of the heat dissipation fins 31 penetrate in the up-down direction. The second pipe section 22 extends in the up-down direction and passes through the through holes. The annular installation cavity 51 extends in the up-down direction, making it easier for each heat dissipation fin 31 to contact and exchange heat with the air on the circumferential outer side of the annular installation cavity 51, which is beneficial to improving the heat exchange efficiency between the heat dissipation member 30 and the outside air and thus improving the heat exchange efficiency between the heat exchange pipe 20 and the heat dissipation member 30.

[0055] In some other embodiments, the annular installation cavity 51 extends in the up-down direction, and the arrangement direction of the plurality of heat dissipation fins 31 forms a certain angle with the up-down direction. For example, the arrangement direction of the plurality of heat dissipation fins 31 forms an angle of 5°, 15° or 30° etc. with the up-down direction, as long as each heat dissipation fin 31 can contact and exchange heat with the outside air, and the heat dissipation member 30 can be flexibly arranged.

[0056] In some embodiments, the inlet 111 is connected to the steam pipe through a flange, a thread or a quick interface, making the connection between the hydrophobic device 100 and the steam pipe firm and convenient for disassembly and assembly. In some embodiments, the outlet 112 is connected to an external component such as the drain pipe 40 through a flange, a thread or a quick interface, making the connection between the hydrophobic device 100 and the external component at the outlet 112 firm and convenient for disassembly and assembly.

[0057] In some embodiments of the present utility model, the heat exchange tube 20 can be one or more, and the number of the heat exchange tubes 20 can be flexibly selected. For example, in some embodiments, the heat exchange tube 20 is one and is a disk-shaped heat exchange tube, so that the contact area between the heat exchange tube 20 and the steam in the accommodation cavity 11 is relatively large, and the heat exchange efficiency between the heat exchange tube 20 and the steam in the accommodation cavity 11 is improved by utilization.

[0058] For another example, in some embodiments, as Figure 1 shown, there are multiple heat exchange tubes 20, and the multiple heat exchange tubes 20 are respectively connected to the heat dissipation member 30. The heat dissipation member 30 exchanges heat with the steam in the accommodation cavity 11 through the heat exchange tubes 20, and the number of the heat exchange tubes 20 is multiple, which is beneficial to increasing the contact area between the heat exchange tubes 20 and the steam in the accommodation cavity 11, so as to improve the heat dissipation effect of the heat dissipation member 30 on the steam in the accommodation cavity 11, and is beneficial to further accelerating the liquefaction speed of the steam in the accommodation cavity 11.

[0059] And the heat dissipation member 30 exchanges heat from the part of the heat exchange tube 20 in contact with the heat dissipation member 30 to the part of the heat exchange tube 20 away from the heat dissipation member 30. For example, heat is exchanged from the second pipe section 22 to the middle of the first pipe section 21. Increasing the number of the heat exchange tubes 20 is beneficial to increasing the contact area between all the heat exchange tubes 20 and the steam in the accommodation cavity 11 while shortening the size of each heat exchange tube 20, so as to reduce the temperature of the part of the heat exchange tube 20 away from the heat dissipation member 30, and further reduce the overall temperature of each heat exchange tube 20, improve the heat exchange efficiency between the heat exchange tube 20 and the steam in the accommodation cavity 11, and accelerate the liquefaction speed of the steam in the accommodation cavity 11.

[0060] In some embodiments where the heat dissipation member 30 is annular, as Figure 1 shown, multiple heat exchange tubes 20 can be arranged around the heat dissipation member 30 at intervals, so that the heat dissipation member 30 exchanges heat with each heat exchange tube 20 evenly, which is beneficial to improving the overall heat exchange efficiency of the heat dissipation member 30 and all the heat exchange tubes 20, and further improving the heat exchange efficiency between all the heat exchange tubes 20 and the steam in the accommodation cavity 11, and accelerating the liquefaction speed of the steam in the accommodation cavity 11.

[0061] In some embodiments, as Figure 1 shown, both ends of the heat exchange tube 20 are connected to the heat dissipation member 30, and the middle part of the heat exchange tube 20 is far away from the heat exchange tube 20, so that the heat dissipation member 30 exchanges heat from both ends of the heat exchange tube 20 to the middle of the heat exchange tube 20, which can reduce the temperature of the middle part of the heat exchange tube 20, so as to reduce the overall temperature of the heat exchange tube 20, and further improve the heat exchange efficiency between the heat exchange tube 20 and the steam in the accommodation cavity 11, and accelerate the liquefaction speed of the steam in the accommodation cavity 11.

[0062] In some embodiments of the present utility model, as Figure 1As shown in the figure, the hydrophobic device 100 includes a plurality of orifice plates 60. The orifice plates 60 are provided with a plurality of holes for fluid to pass through. In the arrangement direction of the inlet 111 and the outlet 112, the plurality of orifice plates 60 are arranged at intervals. The steam and condensate entering the accommodation chamber 11 first pass through the orifice plates 60 and are dispersed, so as to increase the contact area between the steam and the orifice plates 60 and between the condensate and the orifice plates 60, which is beneficial to reducing the steam temperature.

[0063] Then, using Bernoulli's principle, when the fluid passes through the holes, its velocity increases and its kinetic energy increases. Therefore, the pressure energy and potential energy will decrease accordingly. The steam passing through the orifice plate 60 passes through the holes of the orifice plate 60 to reduce the thermal energy of the steam and lower the temperature of the steam, thereby realizing the rapid liquefaction of the steam.

[0064] During the process of the steam flowing from the inlet 111 to the outlet 112, it passes through a plurality of orifice plates 60 to achieve multiple temperature drops of the steam, and the liquefaction speed of the steam is faster.

[0065] In some embodiments, among two adjacent orifice plates 60, the inner diameter of the holes of the orifice plate 60 closer to the outlet 112 is smaller than the inner diameter of the holes of the orifice plate 60 farther from the outlet 112. Based on Bernoulli's principle, when the steam passes through the orifice plate 60 with a constricted cross-section, when the air flow flows from a place with a larger aperture to a place with a smaller aperture, the flow velocity will become faster and the temperature will decrease as the aperture decreases. During the process of the steam flowing from the inlet 111 to the outlet 112, the steam first passes through the holes with a larger inner diameter and then through the holes with a smaller inner diameter, which can further reduce the temperature of the steam at each orifice plate 60 and make the liquefaction speed of the steam faster.

[0066] In some embodiments, as Figure 1 shown, a part of the heat exchange tubes 20 are provided between any two adjacent orifice plates 60, so that the steam cooled by the orifice plate 60 can contact and exchange heat with the heat exchange tubes 20, so as to realize double cooling of the steam through the cooperation of the heat exchange tubes 20 and the heat dissipation parts 30 and the orifice plates 60, further reducing the steam temperature and accelerating the liquefaction speed of the steam.

[0067] In some embodiments, as Figure 1 shown, in the plane perpendicular to the arrangement direction of the inlet 111 and the outlet 112, the heat exchange tubes 20 between two adjacent orifice plates 60 extend along a non-linear path. Here, the non-linear path can be understood as that for the heat exchange tubes 20 between two adjacent orifice plates 60, it does not extend along a straight line from one end to the other end of the heat exchange tubes 20. For example, the heat exchange tubes 20 between two orifice plates 60 extend from one end to the other end in a spiral shape, an arc shape, an irregular curve shape, a broken line shape, etc., or a combination of one or more of them.

[0068] The heat exchange tubes 20 between two adjacent orifice plates 60 extend along a non-linear path to increase the contact area between the heat exchange tubes 20 and the steam between two adjacent orifice plates 60, enabling the steam passing through different parts of the orifice plate 60 to come into contact with the heat exchange tubes 20 as much as possible for heat exchange, improving the heat exchange efficiency between the heat exchange tubes 20 and the steam between adjacent orifice plates 60, and accelerating the liquefaction rate of the steam.

[0069] In some embodiments of the present utility model, as Figure 1 shown, the inlet 111 is provided on the top wall of the device main body 10, and the outlet 112 is provided at the lower part of the device main body 10, such that the inlet 111 is in communication with the steam pipeline in the vertical direction, so as to dispose the steam trap 100 below the steam pipeline, facilitating the vertical installation of the steam trap 100 and enabling the steam trap 100 to adapt to the shape of the steam pipeline extending in the vertical direction.

[0070] In some related technologies, the steam trap is horizontally installed, that is, the inlet and outlet of the steam trap are arranged horizontally, and the inlet of the steam trap is provided on the side of the steam trap. Generally, the steam pipeline extends in the vertical direction. Therefore, when installing the steam trap at the end of the steam pipeline, an L-shaped pipeline needs to be added to connect the end of the steam pipeline and the inlet of the steam trap, resulting in a large loss of pipeline materials.

[0071] In the present application, the inlet 111 and the outlet 112 of the steam trap 100 are arranged in the vertical direction, and the inlet 111 is provided on the top wall of the device main body 10, enabling the vertical installation of the steam trap 100 without adding an L-shaped pipeline to connect the end of the steam pipeline and the inlet 111 of the steam trap 100, reducing the loss of pipeline materials and having better economy.

[0072] In some embodiments of the present utility model, as Figure 1 shown, the steam trap 100 includes a plugging member 70. The plugging member 70 is provided at the outlet 112. The plugging member 70 can plug the outlet 112 under the action of gravity, and the plugging member 70 can open the outlet 112 under the buoyancy of the liquid in the accommodation cavity 11. Here, the liquid refers to condensate or other liquids. In the following, the liquid is taken as condensate for example for description.

[0073] Specifically, the steam and condensate at the end of the steam pipeline enter the accommodation cavity 11. The steam entering the accommodation cavity 11 is liquefied into condensate in the accommodation cavity 11, causing the condensate in the accommodation cavity 11 to gradually increase and the water level in the accommodation cavity 11 to gradually rise. As a result, the plugging member 70 floats under the action of buoyancy to open the outlet 112. After the outlet 112 is opened, the condensate flows out from the outlet 112, and the water level in the accommodation cavity 11 drops, causing the plugging member 70 to gradually fall under its own gravity and finally plug the outlet 112.

[0074] The opening and closing of the outlet 112 is controlled by the buoyancy of the liquid in the accommodation cavity 11 and the gravity of the plugging member 70 itself, with a relatively simple structure and strong practicability. And when the outlet 112 is opened, the outlet 112 is plugged by condensed water to separate the steam pipe and the outside of the outlet 112, realizing water sealing. When the outlet 112 is plugged, the steam pipe and the outside of the outlet 112 are separated by the plugging member 70, so as to separate the steam pipe and the outside of the outlet 112 in both cases of opening and closing of the outlet 112, reducing the adverse impact of the low-temperature environment outside the outlet 112 on the high-temperature environment in the steam pipe and facilitating the maintenance of the high-temperature environment in the steam pipe.

[0075] In some embodiments, as Figure 1 shown, the steam trap 100 includes a seat body 80. The seat body 80 is connected to the device main body 10 and defines a guiding groove 81 extending in the up-down direction. The plugging member 70 includes a floating body 71, a connecting member 72 and a plugging main body 73 connected in sequence. The connecting member 72 is movably inserted into the guiding groove 81 in the up-down direction. The floating body 71 can rise and fall with the change of the water level in the accommodation cavity 11, so as to drive the plugging main body 73 to plug or open the inside of the outlet 112 through the connecting member 72.

[0076] During the process of the floating body 71 floating under the buoyancy force, the floating body 71 drives the connecting member 72 to move upward along the guiding groove 81, and the connecting member 72 drives the plugging main body 73 to move upward to open the outlet 112. During the process of the floating body 71 falling under its own gravity, the floating body 71 drives the connecting member 72 to move downward along the guiding groove 81, and the connecting member 72 drives the plugging main body 73 to move downward to plug the outlet 112.

[0077] The position of the guiding groove 81 in the accommodation cavity 11 is fixed, so as to limit the positions of the floating body 71 and the plugging main body 73 relative to the outlet 112 through the cooperation of the guiding groove 81 and the connecting member 72, so that the plugging main body 73 can plug the outlet 112 without being easily displaced from the outlet 112 after floating up and falling down, making the plugging function of the plugging member 70 more reliable.

[0078] In some embodiments of the present utility model, as Figure 1 shown, an opening 91 communicating with the accommodation cavity 11 is provided in the upper part of the device main body 10. A thermal sensitive element 92 is provided at the opening 91. The thermal sensitive element 92 can open the opening 91 when the temperature in the accommodation cavity 11 is lower than the set temperature, and close the opening 91 when the temperature in the accommodation cavity 11 is higher than or equal to the set temperature.

[0079] There is air in the steam pipe. The air has poor thermal conductivity and is likely to have an adverse impact on the relevant work carried out in the steam pipe. For example, it hinders the heat exchange between the high-temperature steam in the steam pipe and the high-boiling solvent, resulting in incomplete removal of the high-boiling solvent. Therefore, it is necessary to remove the air in the steam pipe.

[0080] The temperature of the air is lower than that of the steam. When the air in the steam pipeline enters the accommodation chamber 11, the temperature in the accommodation chamber 11 becomes lower than the set temperature, causing the thermosensitive element 92 to open the opening 91, so as to discharge the air in the accommodation chamber 11 through the opening 91, and then discharge the air in the steam pipeline. When the steam in the steam pipeline enters the accommodation chamber 11, the temperature in the accommodation chamber 11 becomes higher than or equal to the set temperature, causing the thermosensitive element 92 to close the opening 91, which can prevent the steam from leaking outwards through the opening 91, so as to separate the steam pipeline from the outside world and help maintain the high-temperature environment in the steam pipeline. Here, the set temperature can be understood as the boundary between the air temperature and the steam temperature, and the set temperature can be determined according to specific circumstances.

[0081] For example, before introducing high-temperature steam into the steam pipeline, during the process of just introducing high-temperature steam, or after stopping introducing high-temperature steam for a period of time, the air in the steam pipeline can enter the accommodation chamber 11 to cause the thermosensitive element 92 to open the opening 91. After introducing high-temperature steam into the steam pipeline for a period of time, the steam in the steam pipeline can enter the accommodation chamber 11 to cause the thermosensitive element 92 to close the opening 91.

[0082] The thermosensitive element 92 controls the opening and closing of the opening 91 according to the temperature in the accommodation chamber 11, and there are various ways to set the thermosensitive element 92. For example, in some embodiments, the thermosensitive element 92 directly blocks the opening 91, and the volume of the thermosensitive element 92 is changed by thermal expansion and contraction of the thermosensitive element 92 in the surrounding environment to open and close the opening 91. Also, in some embodiments, the thermosensitive element 92 is arranged near the opening 91 and a valve is provided at the opening 91. The thermosensitive element 92 is connected to the valve. Through the thermal expansion and contraction of the thermosensitive element 92 in the surrounding environment, the thermosensitive element 92 drives the valve to move to open the opening 91 in the contraction state, and the thermosensitive element 92 drives the valve to move to close the opening 91 in the expansion state, etc.

[0083] In some embodiments, as Figure 1 shown, the device main body 10 is provided with a sewage discharge port 93 communicated with the accommodation chamber 11. Welding slag or impurities that may exist in the steam pipeline may enter the accommodation chamber 11 through the inlet 111, and the welding slag or impurities that enter the accommodation chamber 11 can be discharged through the sewage discharge port 93, reducing the possibility of the outlet 112 being blocked and improving the working stability of the steam trap 100.
