Description

Technical Field

[0001] The present invention specifically relates to a water seal device and a manufacturing method thereof, and a water discharge system. Background Art

[0002] As a common pipe fitting in drainage systems, water seal devices are used to prevent gas flow on both sides of the water seal, prevent odor, and block the passage of small organisms such as insects. They are frequently used in drainage systems and are generally purchased directly from standard products in the market.

[0003] In the reprocessing plant, "special wastewater" refers to a type of production wastewater that may contain radioactivity, and its radioactivity level is generally less than or equal to 4×10 6 Bq / L, which belongs to the category of low-level waste liquid. The sources of special sewage mainly include various sanitary entrance and exit personnel washing and disinfection wastewater, radioactive area ground drainage, acid and alkali wastewater generated by process equipment decontamination, and post-treatment and three-waste process discharge radioactive level of production wastewater below the prescribed limit. Because special sewage has certain radioactivity and corrosiveness, the special sewage system has strict requirements on the material, wall thickness and grade of the pipes and fittings used, or has special regulations.

[0004] The material of the pipe fittings of the special drainage system is usually corrosion-resistant materials such as stainless steel. According to the characteristics of the special drainage of a specific project, a variety of different grades of stainless steel materials will be used accordingly, while the grades of stainless steel commonly used in commercially available finished water seal devices are relatively single; the special drainage contains equipment cleaning and decontamination wastewater, which often contains corrosive liquids such as acids and alkalis. When designing the special drainage system, a certain corrosion allowance will be considered, and the requirements for the wall thickness of pipe fittings are usually higher than those of commercially available standard products; in some special cases, the special drainage system will have special requirements in terms of safety, earthquake resistance, quality assurance, etc., and commercially available finished water seal devices cannot meet these requirements. The above situation makes it difficult to directly purchase commercially available finished water seal devices that meet the requirements of the special drainage system, and it is necessary to design non-standard drawings for pre-order purchases. As for the increase in the demand for water seal devices and the change in caliber during the implementation of the project, the cycle of re-customizing non-standard products is long, and the finished products on the market cannot be replaced, which seriously affects the progress of the project. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a water seal device and a manufacturing method thereof, and a special water discharge system in view of the above-mentioned deficiencies in the prior art. The water seal device can be quickly manufactured using existing materials at the place of use and can meet the requirements of the special water discharge system. The manufacturing is convenient and quick, and the production cycle of the water seal device can be reduced.

[0006] In a first aspect, an embodiment of the present invention provides a method for manufacturing a water seal device, which is applied to a special drainage system. The manufacturing method comprises: at the place of use, using the pipes available on site that can meet the requirements of the special drainage system as raw materials to respectively manufacture an inlet pipe and an outlet pipe, and a sleeve; extending the lower end of the inlet pipe into the sleeve from the upper port of the sleeve; manufacturing a first sealing plate, and using the first sealing plate to seal the portion between the upper port of the sleeve and the inlet pipe, so as to fix the inlet pipe on the sleeve; opening a through hole on the side wall of the sleeve, the position of the through hole is above the lower port of the inlet pipe, and the outlet pipe is inserted into the interior of the sleeve through the through hole, so as to seal and fix the outlet pipe on the side wall of the sleeve; manufacturing a second sealing plate, and using the second sealing plate to seal the lower port of the sleeve.

[0007] In some embodiments, the sleeve is made by: using pipes available on site that can meet the requirements of a special water supply system as raw materials to make the sleeve; or using plates available on site that can meet the requirements of a special water supply system as raw materials to make the sleeve.

[0008] In some embodiments, the making of the first sealing plate is specifically: making the first sealing plate with a plate material and thickness same as the sleeve available on site. The making of the second sealing plate is specifically: making the second sealing plate with a plate material and thickness same as the sleeve available on site.

[0009] In some embodiments, after manufacturing the second sealing plate and before using the second sealing plate to seal the lower port of the sleeve, the manufacturing method also includes: opening a first cleaning hole on the second sealing plate, the first cleaning hole being able to correspond to the water inlet pipe in the vertical direction; and sealing the first cleaning hole with detachable standard parts available on site.

[0010] Therefore, the method for making a water seal device provided by an embodiment of the present invention can make the water inlet pipe and the water outlet pipe respectively at the place of use by using the pipes available on site that can meet the requirements of the special drainage system as raw materials, and can use the pipes on site to quickly make water inlet pipes and water outlet pipes of various diameters, and the manufactured water inlet pipes and water outlet pipes can also meet the requirements of the special drainage system for radioactivity and corrosion resistance; by making a sleeve, a first sealing plate and a second sealing plate, the water inlet pipe and the water outlet pipe can be fixed on the sleeve to form a water seal device. Therefore, the method for making a water seal device provided by an embodiment of the present invention can use existing materials at the place of use to quickly make a water seal device that meets the requirements of the special drainage system. Compared with the prior art, when the demand for the water seal device is increased or the caliber of the water seal device is changed during the implementation of the project, the time required for pre-customization and procurement can be saved. Therefore, the method of the present invention can effectively reduce the production cycle of the water seal device and avoid affecting the progress of the project.

[0011] In a second aspect, an embodiment of the present invention also provides another method for manufacturing a water seal device, which is applied to a special drainage system and is characterized in that the manufacturing method comprises: at the place of use, using the pipes available on site that can meet the requirements of the special drainage system as raw materials to respectively manufacture an inlet pipe and an outlet pipe, and a sleeve; extending the lower end of the inlet pipe into the sleeve from the upper port of the sleeve; manufacturing a third sealing plate, and using the third sealing plate to seal the portion between the upper port of the sleeve and the inlet pipe to fix the inlet pipe on the sleeve; extending the upper end of the outlet pipe into the sleeve from the lower port of the sleeve, so that the upper port of the outlet pipe is above the lower port of the inlet pipe; manufacturing a fourth sealing plate, and using the fourth sealing plate to seal the portion between the lower port of the sleeve and the outlet pipe to fix the outlet pipe on the sleeve.

The making of the fourth sealing plate is specifically: making the fourth sealing plate with a plate material and thickness same as the sleeve available on site.

[0014] In some embodiments, after making the third sealing plate, before using the third sealing plate to seal the portion between the upper port of the sleeve and the water inlet pipe, the manufacturing method further includes: opening a second cleaning hole on the third sealing plate, the second cleaning hole being able to correspond to the upper port of the water outlet pipe in the vertical direction; sealing the second cleaning hole with detachable standard parts available on site; and / or, after making the fourth sealing plate, before using the fourth sealing plate to seal the portion between the lower port of the sleeve and the water outlet pipe, the manufacturing method further includes: opening a third cleaning hole on the fourth sealing plate, the third cleaning hole being able to correspond to the lower port of the water inlet pipe in the vertical direction; sealing the third cleaning hole with detachable standard parts available on site.

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0026] Embodiment 1:

[0027] like Figure 1 As shown, an embodiment of the present invention provides a method for manufacturing a water seal device, such as Figure 2 and Figure 3 As shown, the water seal device is used in a special water system to seal the pipes on both sides of the water seal device to prevent the gas in the pipes on both sides of the water seal device from flowing to each other. The manufacturing method includes: steps S100-S500.

[0028] S100. At the use site, use the pipes available on site that can meet the requirements of the special sewer system as raw materials to respectively manufacture the water inlet pipe 1 and the water outlet pipe 2, and manufacture the sleeve 3.

[0029] S200, extending the lower end of the water inlet pipe 1 into the sleeve 3 through the upper end of the sleeve 3.

[0030] S300 , making a first sealing plate 41 , and using the first sealing plate 41 to seal the portion between the upper end of the sleeve 3 and the water inlet pipe 1 , so as to fix the water inlet pipe 1 on the sleeve 3 .

[0031] S400, a through hole is opened on the side wall of the sleeve 3, the position of the through hole is above the lower end of the water inlet pipe 1, and the water outlet pipe 2 is inserted into the sleeve 3 through the through hole to seal and fix the water outlet pipe 2 on the side wall of the sleeve 3.

[0032] S500 , manufacturing a second sealing plate 42 , and using the second sealing plate 42 to seal the lower end of the sleeve 3 .

[0033] For example, special sewer system requirements may include requirements for material, thickness, grade, etc.

[0034] It is understandable that when making a special sewage system, there are many pipes with different diameter grades that meet the requirements of the special sewage system at the place of use. Therefore, the pipes available on site can be conveniently used to make water inlet pipes 1 and water outlet pipes 2 of various diameters, and the manufactured water inlet pipes 1 and water outlet pipes 2 also meet the requirements of the special sewage system for anti-radiation and anti-corrosion; and, the diameters of the water inlet pipes 1 and the water outlet pipes 2 are the same as the diameters of the pipes required by the special sewage system on site. Therefore, there is no need to perform special processing on the water inlet pipes 1 and the water outlet pipes 2 or add reducers, so that the water inlet pipes 1 and the water outlet pipes 2 can be conveniently connected to other upstream and downstream pipes in the special sewage system, so that the finally formed water seal device can be suitable for upstream and downstream pipes of various diameter ranges, thereby enhancing compatibility with upstream and downstream pipes; further, the water inlet pipes 1 and the water outlet pipes 2 are made using the pipes on site, which also reduces the manufacturing costs of the water inlet pipes 1 and the water outlet pipes 2, thereby reducing the manufacturing costs of the water seal device.

[0035] Exemplarily, the water inlet pipe 1, the water outlet pipe 2 and the upstream and downstream pipelines can be connected by welding, flange, thread, groove, socket, etc. The water inlet pipe 1 is arranged vertically, and the water outlet pipe 2 is arranged horizontally.

[0036] Exemplarily, the inner diameter of the sleeve 3 is greater than the outer diameter of the water inlet pipe 1 , so that the water inlet pipe 1 can be inserted into the sleeve 3 .

[0037] Exemplarily, the first sealing plate 41 is perforated according to the outer diameter of the water inlet pipe 1, so as to facilitate the sealing between the water inlet pipe 1 and the first sealing plate 41 after the water inlet pipe 1 is inserted into the first sealing plate 41. The first sealing plate 41 is welded between the upper end of the sleeve 3 and the water inlet pipe 1 to fix the water inlet pipe 1 on the sleeve 3. The second sealing plate 42 is welded on the lower end of the sleeve 3.

[0038] Exemplarily, the size of the through hole on the side wall of the sleeve 3 is the same as the outer diameter of the water outlet pipe 2, so that the water outlet pipe 2 can be just inserted into the through hole on the side wall of the sleeve 3, which facilitates the subsequent sealing between the water outlet pipe 2 and the side wall of the sleeve 3.

[0039] like Figure 3 As shown, the arrow direction in the figure is the flow direction of the special water in the water seal device. After the outlet pipe 2 is inserted into the sleeve 3 through the through hole, the port on the left side of the outlet pipe 2 will be higher than the lower port of the inlet pipe 1. After the special water enters the sleeve 3 from the inlet pipe 1, the water level gradually rises, and then submerges the lower port of the inlet pipe 1. As the water level continues to rise, when the water level of the special water is higher than the outlet pipe 2, the special water higher than the outlet pipe 2 will flow out from the outlet pipe 2. After all the special water in the outlet pipe 2 flows out, a part of the special water will remain in the sleeve 3 and cannot be discharged, so as to seal the part between the inlet pipe 1 and the outlet pipe 2, so as to avoid the air in the inlet pipe 1 and the outlet pipe 2 from circulating with each other when there is no special water flowing in the inlet pipe 1 and the outlet pipe 2, so as to ensure the water seal function of the water seal device.

[0040] Therefore, the method for making a water seal device provided in an embodiment of the present invention can make the water inlet pipe 1 and the water outlet pipe 2 temporarily on site respectively at the place of use, using the pipes available on site that can meet the requirements of the special drainage system as raw materials, and can use all the pipes on site to quickly make water inlet pipes 1 and water outlet pipes 2 of various diameters, and the completed water inlet pipes 1 and water outlet pipes 2 also meet the requirements of the special drainage system for radioactivity and corrosion resistance; by making the sleeve 3, the first sealing plate 41 and the second sealing plate 42, the water inlet pipe 1 and the water outlet pipe 2 can be fixed on the sleeve 3 to form a water seal device. Therefore, the method for making a water seal device provided in an embodiment of the present invention can use existing materials at the place of use to quickly make a water seal device that meets the requirements of the special drainage system. Compared with the prior art, when the demand for the water seal device is increased or the caliber of the water seal device is changed during the implementation of the project, the time required for pre-customization and procurement can be saved, so the production cycle of the water seal device can be reduced to avoid affecting the progress of the project.

[0041] Furthermore, compared with purchasing water seal devices from outside, the cost of making water seal devices on site is lower, which is conducive to reducing costs and increasing efficiency; and the pipe diameters of the water inlet pipe 1 and the water outlet pipe 2 can be flexibly selected according to the pipe diameters of the upstream and downstream pipelines, thereby increasing the compatibility of the final water seal device with the upstream and downstream pipelines.

[0042] In some embodiments, in the above step S100, making the sleeve 3 specifically includes: using the pipes available on site that can meet the requirements of the special drainage system as raw materials to make the sleeve 3; or using the plates available on site that can meet the requirements of the special drainage system as raw materials to make the sleeve 3.

[0043] It can be understood that the inner diameter of the sleeve 3 needs to be larger than the outer diameter of the water inlet pipe 1. When the outer diameter of the water inlet pipe 1 is smaller, the sleeve 3 can be made of a pipe with a larger outer diameter than the water inlet pipe 1 and meeting the requirements of the special sewer system as raw material, that is, directly using the pipes on site.

[0044] When the outer diameter of the water inlet pipe 1 is large, the inner diameter of the sleeve 3 may exceed the diameter grade range of the existing pipes in the special drainage system. At this time, the sleeve 3 can be made by rolling and welding a plate that meets the requirements of the special drainage system (material, grade requirements, etc.). At this time, the wall thickness of the plate that meets the requirements of the special drainage system is required to be no less than the maximum wall thickness of the pipe in the special drainage system.

[0045] In this way, the sleeve 3 can be made by flexibly utilizing materials on site according to demand, and the water seal device can be made more conveniently and quickly by utilizing existing materials at the place of use, thereby further reducing the production cycle of the water seal device.

[0046] In some embodiments, in the above step S300, the first sealing plate 41 is made by using a plate material and thickness same as the sleeve 3 available on site. In the above step S500, the second sealing plate 42 is made by using a plate material and thickness same as the sleeve 3 available on site.

[0047] For example, the first sealing plate 41 may be formed by cutting a plate, and the second sealing plate 42 may be formed by cutting a plate.

[0048] In this way, the first sealing plate 41 and the second sealing plate 42 can be quickly made on site using existing materials, reducing the types of materials that need to be prepared on site, and making the first sealing plate 41 and the second sealing plate 42 have the same strength and protective effect as the sleeve 3, ensuring the normal service life of the water sealing device.

[0049] In some embodiments, Figure 3 As shown, after the second sealing plate 42 is manufactured and before the second sealing plate 42 is used to seal the lower port of the sleeve 3, the manufacturing method also includes: opening a first cleaning hole 51 on the second sealing plate 42, the first cleaning hole 51 being able to correspond to the water inlet pipe 1 in the vertical direction; and sealing the first cleaning hole 51 with detachable standard parts available on site.

[0050] For example, Figure 3 As shown, the first cleaning hole 51 is radially aligned with the center of the lower end of the water inlet pipe 1. In this way, the first cleaning hole 51 can directly pass through the water inlet pipe 1, and when the water inlet pipe 1 of the water seal device is blocked, a cleaning tool can be inserted into the water inlet pipe 1 through the first cleaning hole 51 for cleaning.

[0051] Exemplarily, the first cleaning hole 51 may be a threaded hole, and the first cleaning hole 51 is sealed by a detachable screw.

[0052] The detachable standard part can facilitate opening the first cleaning hole 51, so that the water inlet pipe 1 can be cleaned through the first cleaning hole 51 when the water sealing device is blocked.

[0053] Embodiment 2:

[0054] like Figure 4 As shown, the embodiment of the present invention also provides another method for manufacturing a water seal device, such as Figure 5 and Figure 6 As shown, the water seal device is used in a special water system to seal the gas on both sides of the water seal device and prevent the flow of gas on both sides of the water seal device. The manufacturing method includes: steps S100'-S500'.

[0055] S100', at the use site, using the pipes available on site that can meet the requirements of the special sewer system as raw materials to respectively manufacture the water inlet pipe 1 and the water outlet pipe 2, and manufacture the sleeve 3.

[0056] S200 ′, extending the lower end of the water inlet pipe 1 into the sleeve 3 through the upper end of the sleeve 3 .

[0057] S300 ′, making a third sealing plate 43 , and using the third sealing plate 43 to seal the portion between the upper end of the sleeve 3 and the water inlet pipe 1 , so as to fix the water inlet pipe 1 on the sleeve 3 .

[0058] S400 ′, extend the upper end of the water outlet pipe 2 into the sleeve 3 from the lower end of the sleeve 3 , so that the upper end of the water outlet pipe 2 is above the lower end of the water inlet pipe 1 .

[0059] S500 ′, making a fourth sealing plate 44 , and using the fourth sealing plate 44 to seal the portion between the lower end of the sleeve 3 and the water outlet pipe 2 , so as to fix the water outlet pipe 2 on the sleeve 3 .

[0060] Different from the embodiment 1, in this embodiment, the water inlet pipe 1 and the water outlet pipe 2 are both arranged vertically.

[0061] like Figure 6 As shown, the arrow direction in the figure is the flow direction of the special water in the water seal device. After the outlet pipe 2 is inserted into the sleeve 3 through the through hole, the upper end of the outlet pipe 2 will be higher than the lower end of the inlet pipe 1. After the special water enters the sleeve 3 from the inlet pipe 1, the water level gradually rises, and then submerges the lower end of the inlet pipe 1. As the water level continues to rise, when the water level of the special water is higher than the upper end of the outlet pipe 2, the special water higher than the upper end of the outlet pipe 2 will flow out from the outlet pipe 2. After all the special water in the outlet pipe 2 flows out, a part of the special water will remain in the sleeve 3 and cannot be discharged, so as to seal the part between the inlet pipe 1 and the outlet pipe 2, so as to avoid the air in the inlet pipe 1 and the outlet pipe 2 from circulating with each other when there is no special water flowing in the inlet pipe 1 and the outlet pipe 2, so as to ensure the water seal function of the water seal device.

[0062] Similar to the manufacturing method of the water seal device in Example 1, the manufacturing method of the water seal device provided in the embodiment of the present invention can use existing materials at the place of use to quickly manufacture a water seal device that meets the requirements of a special drainage system. Compared with the existing technology, when the demand for water seal devices increases or the caliber of water seal devices is changed during the implementation of the project, the time required for pre-customization and procurement can be saved, thereby reducing the production cycle of the water seal device and avoiding affecting the progress of the project.

[0063] In some embodiments, in the above step S100', the sleeve 3 is manufactured by: using the pipes available on site that can meet the requirements of the special water supply system as raw materials to manufacture the sleeve 3; or using the plates available on site that can meet the requirements of the special water supply system as raw materials to manufacture the sleeve 3.

[0064] It is understandable that the inner diameter of the sleeve 3 needs to be larger than the outer diameter of the water inlet pipe 1. When the outer diameter of the water inlet pipe 1 is smaller, the sleeve 3 can be made of a pipe with a larger outer diameter than the water inlet pipe 1 that meets the requirements of the special sewer system as raw material.

[0065] When the outer diameter of the water inlet pipe 1 is large, the inner diameter of the sleeve 3 may exceed the diameter grade range of the existing pipes in the special drainage system. At this time, the sleeve 3 can be made by rolling and welding a plate that meets the requirements of the special drainage system (material, grade requirements, etc.). At this time, the wall thickness of the plate that meets the requirements of the special drainage system is required to be no less than the maximum wall thickness of the pipe in the special drainage system.

[0066] In this way, the sleeve 3 can be manufactured conveniently using materials available on site, so that the water seal device can be manufactured quickly using existing materials at the use site, thereby reducing the manufacturing cycle of the water seal device.

[0067] In some embodiments, in the above step S300', the third sealing plate 43 is made by using a plate having the same material and thickness as the sleeve 3. In the above step S500', the fourth sealing plate 44 is made by using a plate having the same material and thickness as the sleeve 3.

[0068] For example, the third sealing plate 43 may be formed by cutting a plate. The fourth sealing plate 44 may be formed by cutting a plate.

[0069] In this way, the third sealing plate 43 and the fourth sealing plate 44 can be quickly manufactured on site using existing materials, and the third sealing plate 43 and the fourth sealing plate 44 have the same strength and protective effect as the sleeve 3, ensuring the normal use of the water sealing device.

[0070] In some embodiments, after the third sealing plate 43 is manufactured, before the third sealing plate 43 is used to seal the portion between the upper port of the sleeve 3 and the water inlet pipe 1, as shown in FIG. Figure 6 As shown, the manufacturing method also includes: opening a second cleaning hole 52 on the third sealing plate 43, the second cleaning hole 52 can correspond to the upper end of the water outlet pipe 2 in the vertical direction; and sealing the second cleaning hole 52 with detachable standard parts available on site.

[0071] For example, Figure 6As shown, the second cleaning hole 52 is radially aligned with the center of the upper end of the water outlet pipe 2. In this way, the second cleaning hole 52 can directly pass through the water outlet pipe 2, and when the water outlet pipe 2 of the water seal device is blocked, a cleaning tool can be inserted into the water outlet pipe 2 through the second cleaning hole 52 for cleaning.

[0072] Exemplarily, the second cleaning hole 52 may be a threaded hole, and the second cleaning hole 52 is sealed by a screw to facilitate opening the second cleaning hole 52 .

[0073] The second cleaning hole 52 can be used to clean the water outlet pipe 2 when the water sealing device is blocked.

[0074] In some embodiments, after the fourth sealing plate 44 is manufactured, before the fourth sealing plate 44 is used to seal the portion between the lower port of the sleeve 3 and the water outlet pipe 2, as shown in FIG. Figure 6 As shown, the manufacturing method also includes: opening a third cleaning hole 53 on the fourth sealing plate 44, the third cleaning hole 53 can correspond to the lower end of the water inlet pipe 1 in the vertical direction; and sealing the third cleaning hole 53 with detachable standard parts available on site.

[0075] For example, Figure 6 As shown, the third cleaning hole 53 is radially aligned with the center of the lower end of the water inlet pipe 1. In this way, the third cleaning hole 53 can directly pass through the water inlet pipe 1, and when the water inlet pipe 1 of the water seal device is blocked, a cleaning tool can be inserted into the water inlet pipe 1 through the third cleaning hole 53 for cleaning.

[0076] Exemplarily, the third cleaning hole 53 may be a threaded hole, and the third cleaning hole 53 is sealed by a screw, which makes it easy to open the third cleaning hole 53.

[0077] The third cleaning hole 53 can be used to clean the water inlet pipe 1 when the water seal device is blocked.

[0078] Embodiment 3:

[0079] The embodiment of the present invention also provides a water seal device, such as Figure 2 and Figure 3 As shown, the water seal device is manufactured by the manufacturing method of the water seal device in Example 1; or Figure 5 and Figure 6 As shown, the water seal device is manufactured by the manufacturing method of the water seal device in Example 2.

[0080] The water inlet pipe 1 and the water outlet pipe 2 of the water seal device are made of pipes that meet the requirements of the special sewage system as raw materials. Therefore, the completed water inlet pipe 1 and the water outlet pipe 2 can meet the requirements of the special sewage system for radioactivity protection and corrosion resistance, and the diameters of the water inlet pipe 1 and the water outlet pipe 2 can be made the same as the diameters of the pipes of the on-site special sewage system. Therefore, there is no need to perform special processing on the water inlet pipe 1 and the water outlet pipe 2 or add reducers, so the water inlet pipe 1 and the water outlet pipe 2 can be conveniently connected to other upstream and downstream pipes in the special sewage system, thereby enhancing the compatibility of the water seal device; further, the water inlet pipe 1 and the water outlet pipe 2 are made using on-site pipes, which is conducive to the rapid production of water seal devices that meet the requirements of the special sewage system using existing materials at the place of use. Compared with the prior art, when the demand for water seal devices increases or the caliber of the water seal devices is changed during the implementation of the project, the time required for pre-customization and procurement is saved, thereby reducing the production cycle of the water seal device, and when the demand for water seal devices increases or the caliber is changed during the implementation of the project, the impact on the progress of the project can be avoided.

[0081] In some embodiments, the outer diameters of the water inlet pipe 1 and the water outlet pipe 2 are both D.

[0082] Exemplarily, the value of D may be 20 mm, 30 mm, or 35 mm, etc.

[0083] like Figure 2 and Figure 3 As shown, the water seal device is manufactured by the manufacturing method of the water seal device in Example 1, and the inner diameter D1 of the sleeve 3 satisfies: D1 ≥ 2D; the spacing L1 between the lower port of the water inlet pipe 1 and the second sealing plate 42 is greater than or equal to D; the minimum spacing L2 between the water outlet pipe 2 and the lower port of the water inlet pipe 1 is greater than or equal to 50 mm.

[0084] Exemplarily, when the outer diameter D of the water inlet pipe 1 and the water outlet pipe 2 is 20 mm, the inner diameter D1 of the sleeve 3 satisfies: D1 ≥ 40 mm. For example, the inner diameter D1 of the sleeve 3 may be 40 mm, 60 mm or 80 mm.

[0085] The inner diameter D1 of the sleeve 3 is large, so that after the water inlet pipe 1 is inserted into the sleeve 3, there is enough gap between the outer wall of the water inlet pipe 1 and the inner wall of the sleeve 3 to allow the special water in the sleeve 3 to pass through and flow out from the water outlet pipe 2, avoiding affecting the flow rate of the special water in the sleeve 3.

[0086] For example, when the outer diameter D of the water inlet pipe 1 and the water outlet pipe 2 is 20 mm, the distance L1 between the lower end of the water inlet pipe 1 and the second sealing plate 42 can be 20 mm, 30 mm or 50 mm.

[0087] The distance L1 between the lower end of the water inlet pipe 1 and the second sealing plate 42 is large, so that the special water in the water inlet pipe 1 has enough space to enter the sleeve 3, avoiding affecting the flow rate of the special water in the water inlet pipe 1, and avoiding clogging of the water seal device when there are debris in the special water, and facilitating cleaning of the water seal device when it is blocked.

[0088] like Figure 3 As shown, the minimum distance (also referred to as the structural dimension) between the water outlet pipe 2 and the lower end of the water inlet pipe 1 is L2, and the dimension of L2 can be 50 mm, 60 mm or 70 mm, etc.

[0089] It can be understood that after the special water in the water seal device stops flowing, the special water retained in the sleeve 3 forms a water seal, and the height of the water seal is L2. By making L2 greater than or equal to 50 mm, the height of the water seal can be made higher, so that the water seal device can maintain a better water seal effect.

[0090] In some examples, such as Figure 3 As shown, the length of the water inlet pipe 1 outside the sleeve 3 is L3, L3≥2D; the length of the water outlet pipe 2 outside the sleeve 3 is L4, L4≥2D.

[0091] For example, when the value of the outer diameter D of the water inlet pipe 1 and the water outlet pipe 2 is 20 mm, the length L3 of the water inlet pipe 1 outside the sleeve 3 satisfies: L3 ≥ 40 mm, for example, the inner diameter L3 of the sleeve 3 may be 40 mm, 50 mm or 60 mm, etc. The length L4 of the water outlet pipe 2 outside the sleeve 3 satisfies: L4 ≥ 40 mm, for example, the length L4 of the water outlet pipe 2 outside the sleeve 3 may be 40 mm, 50 mm or 60 mm, etc.

[0092] The above arrangement can facilitate the connection between the water inlet pipe 1, the water outlet pipe 2 and the upstream and downstream pipelines.

[0093] like Figure 5 and Figure 6 As shown, the water seal device is manufactured by the manufacturing method of the water seal device in Example 2, and the inner diameter D2 of the sleeve 3 satisfies: 2D≤D2≤3D; the distance L5 between the lower port of the water inlet pipe 1 and the fourth sealing plate 44 is greater than or equal to D, and the distance L6 between the upper port of the water outlet pipe 2 and the third sealing plate 43 is greater than or equal to D; the minimum distance between the upper port of the water outlet pipe 2 and the lower port of the water inlet pipe 1 is greater than or equal to 50 mm.

[0094] Exemplarily, when the outer diameter D of the water inlet pipe 1 and the water outlet pipe 2 is 20 mm, the inner diameter D2 of the sleeve 3 satisfies: 40 mm ≤ D2 ≤ 60 mm. For example, the inner diameter D2 of the sleeve 3 can be 40 mm, 50 mm or 60 mm.

[0095] like Figure 6As shown, after the inner diameter D2 of the sleeve 3 satisfies 2D≤D2≤3D, the water inlet pipe 1 and the water outlet pipe 2 can be inserted into the interior of the sleeve 3 at the same time, so that there is enough space between the water inlet pipe 1, the water outlet pipe 2 and the inner wall of the sleeve 3 to allow the special water to flow normally, avoiding affecting the flow rate of the special water in the sleeve 3 and avoiding the outer dimensions of the water seal device being too large due to the inner diameter of the sleeve 3 being too large.

[0096] Exemplarily, when the outer diameter D of the water inlet pipe 1 and the water outlet pipe 2 is 20 mm, the distance L5 between the lower port of the water inlet pipe 1 and the fourth sealing plate 44 is greater than or equal to 20 mm. For example, the distance L5 between the lower port of the water inlet pipe 1 and the fourth sealing plate 44 can be 20 mm, 40 mm or 50 mm, etc.

[0097] The distance L5 between the lower end of the water inlet pipe 1 and the fourth sealing plate 44 is large, so that the special water in the water inlet pipe 1 has enough space to enter the sleeve 3, avoiding affecting the flow rate of the special water in the water inlet pipe 1, avoiding clogging of the water seal device when there are debris in the special water, and facilitating cleaning of the water seal device when it is blocked.

[0098] Exemplarily, when the outer diameter D of the water inlet pipe 1 and the water outlet pipe 2 is 20 mm, the distance L6 between the upper port of the water outlet pipe 2 and the third sealing plate 43 is greater than or equal to 20 mm. For example, the distance L6 between the upper port of the water outlet pipe 2 and the third sealing plate 43 can be 20 mm, 40 mm or 50 mm, etc.

[0099] The distance L6 between the upper end of the water outlet pipe 2 and the third sealing plate 43 is large, so that the special water in the sleeve 3 has enough space to enter the water outlet pipe 2, avoiding affecting the flow rate of the special water in the sleeve 3, avoiding clogging of the water seal device when there are debris in the special water, and facilitating cleaning of the water seal device when it is blocked.

[0100] like Figure 6 As shown, the minimum distance (also referred to as the structural dimension) between the upper end of the water outlet pipe 2 and the lower end of the water inlet pipe 1 is L7, and the dimension of L7 can be 50 mm, 60 mm or 70 mm, etc.

[0101] It can be understood that after the special water in the water seal device stops flowing, the special water retained in the sleeve 3 forms a water seal, and the height of the water seal is L7. By making L7 greater than or equal to 50 mm, the height of the water seal can be made higher, so that the water seal device can maintain a better water seal effect.

[0102] Embodiment 4:

[0103] The embodiment of the present invention further provides a special drainage system, which is applied to a post-processing plant, and includes a drainage device, a water seal device in Embodiment 3, and a drainage pipe. The drainage device has a drainage port for discharging special drainage water through the drainage port. The water inlet pipe 1 of the water seal device is connected to the drainage port of the drainage device. The drainage pipe is connected to the water outlet pipe 2 of the water seal device.

[0104] The water seal device in Example 3 can be quickly manufactured using existing materials at the site of use. Compared with purchasing commercially available finished water seal devices, it saves the time required for pre-customization and procurement, thereby reducing the production cycle of the water seal device. In the event of increased demand for water seal devices and changes in caliber during project implementation, it can avoid affecting the progress of the special drainage system project.
