Description

Technical Field

[0001] This utility model belongs to the field of liquid sampling technology, specifically relating to an automatic liquid collection device for a sampling valve. Background Technology

[0002] In the production processes of industries such as chemicals and pharmaceuticals, taking samples from the process pipelines for analysis is a crucial step in ensuring the quality of the production process and the final product.

[0003] In existing technologies, sampling is usually done manually. However, this process requires opening and closing sampling valves. After sampling is completed and the valves are closed, droplets of liquid can fall onto the ground, causing the chemical sample droplets to evaporate into the atmosphere. This can lead to unpleasant odors during chemical and pharmaceutical plant production, affecting the health and well-being of employees and those in the vicinity. Furthermore, if the droplets are not cleaned up promptly, they become increasingly difficult to remove over time, especially in outdoor workplaces where concrete surfaces are common. The liquid can seep into the ground, causing discoloration and impacting the overall hygiene of the production area. In special circumstances, this can also pose a safety hazard to the production site. Utility Model Content

[0035] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0036] Please refer to the following: Figure 1 , Figure 3 and Figure 7 The automatic liquid collection device for sampling valves provided by this utility model will now be described. The automatic liquid collection device for sampling valves includes a fixing structure 10, a collection tank 20, and a disassembly structure 30. The fixing structure 10 is fixed to the sampling valve 40 and has a through hole through which the outlet of the sampling valve 40 passes vertically. The collection tank 20 is located below the fixing structure 10 and has an open collection cavity corresponding to the outlet of the sampling valve 40. The open portion of the collection tank 20 has an annular contact surface that can seal against the fixing structure 10. The disassembly structure 30 allows for detachable connection between the fixing structure 10 and the collection tank 20.

[0037] Compared with the prior art, the automatic liquid collection device for the sampling valve provided in this embodiment has a collection tank 20 located below the fixed structure 10. A through-hole in the fixed structure 10 allows the outlet of the sampling valve 40 to pass through, ensuring complete collection of droplets dripping from the outlet of the sampling valve 40 and preventing droplets from falling to the ground. The collection tank 20 is detachably connected to the fixed structure 10 via the disassembly structure 30, allowing for easy transfer of the collection tank 20 for sampling purposes. Furthermore, the annular contact surface at the top of the collection tank 20 ensures a seal with the fixed structure 10 and prevents droplets from evaporating into the environment.

[0038] It should be noted that the outlet of the sampling valve 40 is usually vertically downward. This technology is existing technology and will not be described in detail here.

[0039] In some embodiments, the fixing structure 10 described above can be as follows: Figure 1 , Figure 3 and Figure 7 The structure shown. See also Figure 1 , Figure 3 and Figure 7The bottom end of the fixing structure 10 is provided with an annular sealing ring corresponding to the annular contact surface. The annular sealing ring can further increase the sealing effect, thereby effectively preventing droplets from evaporating into the atmosphere and avoiding pollution of the nearby environment.

[0040] The fixed structure 10, the collection bucket 20, and the detachable structure 30 have three forms, or three specific implementation methods. Among them,

[0041] Example 1:

[0042] In some embodiments, the fixing structure 10 described above can be as follows: Figures 1 to 2 The structure shown. See also Figures 1 to 2 The fixed structure 10 includes a cover plate 11, which is fixedly mounted on the sampling valve 40 in a horizontal direction. The central hole on the cover plate 11 is a through hole.

[0043] The cover plate 11 is fixed on the sampling valve 40, and the outlet of the sampling valve 40 passes through its central hole, which can ensure that the cover plate 11 and the sampling valve 40 are integrally connected, and at the same time ensure that the dripping droplets are located below the cover plate 11.

[0044] In this embodiment, the cover plate 11 can be a circular plate or a rectangular plate. Correspondingly, the shape of the collection bucket 20 needs to match the shape of the cover plate 11 to ensure convenient connection between the two.

[0045] In some embodiments, the above-described disassembly and assembly structure 30 may adopt the following... Figures 1 to 2 The structure shown. See also Figures 1 to 2 The disassembly and assembly structure 30 includes a hydraulic hinge 31. The pivot of the hydraulic hinge 31 is horizontally arranged and has two relatively rotatable connecting ends. One connecting end is fixedly connected to the cover plate 11, and the other connecting end is connected to the outer wall of the collection bucket 20. The hydraulic hinge 31 enables the collection bucket 20 to maintain a tendency to continuously tilt upward and flip until the annular contact surface abuts against the cover plate 11.

[0046] The hydraulic hinge 31 is existing technology. It connects the collection bucket 20 to the cover plate 11, allowing the collection bucket 20 to rotate relative to the cover plate 11. When rotating downwards, it releases the seal with the cover plate 11, allowing sampling through the outlet of the sampling valve 40. When rotating upwards to a vertical position, the collection bucket 20 abuts against the cover plate 11, forming a seal. The hydraulic hinge 31 itself has a spring-like effect, continuously springing the collection bucket 20. Even without external force, the annular contact surface at the top of the collection bucket 20 continues to abut against the cover plate 11. This structure is easy for operators to use, simple in design, requiring only the movement of the collection bucket 20 to open the sampling valve 40 for sampling.

[0047] It should be noted that, to further enhance the rebound effect of the collection bucket 20, i.e., to allow it to rotate upwards to a vertical position, a tension spring can be connected to the collection bucket 20. The other end of the tension spring is connected to the cover plate 11, and the tension spring works in conjunction with the hydraulic hinge 31. Two tension springs can be provided, located on opposite sides of the collection bucket 20 along the axis of the hydraulic hinge 31 to ensure the rebound effect.

[0048] In another embodiment of the disassembly structure 30, when the collection bucket 20 is small in size and light in weight, the disassembly structure 30 may include a torsion spring. The axis of the torsion spring is arranged parallel to the cover plate 11. One end of the torsion spring is fixed on the cover plate 11. The torsion spring has an elastic connecting end, which is fixedly connected to the collection bucket 20. The torsion spring can continuously bounce the collection bucket 20 so that the collection bucket 20 has a continuous tendency to tilt and flip upward, that is, to ensure that the collection bucket 20 continues to abut against the cover plate 11 without the action of external force.

[0049] Example 2:

[0050] In some embodiments, the fixing structure 10 described above can be as follows: Figures 3 to 6 The structure shown. See also Figures 3 to 6 The fixed structure 10 includes a cover plate 11, which is fixedly mounted on the sampling valve 40 in a horizontal direction. The opening in the cover plate 11 is a through hole. The bottom surface of the cover plate 11 is provided with a first groove 12 that communicates with the through hole and provides a space for the outlet of the sampling valve 40.

[0051] The cover plate 11 ensures a fixed connection with the sampling valve 40, and the outlet of the sampling valve 40 passes through its opening, ensuring an integral connection between the cover plate 11 and the sampling valve 40, while also ensuring that the dripping droplets are located below the cover plate 11. In addition, a first groove 12 is provided on the bottom surface of the cover plate 11 to ensure that the bottom of the outlet of the sampling valve 40 is higher than the bottom surface of the cover plate 11, preventing the outlet of the sampling valve 40 from obstructing the movement of the collection bucket 20.

[0052] In some embodiments, the above-described disassembly and assembly structure 30 may adopt the following... Figures 3 to 6 The structure shown. See also Figures 3 to 6 The disassembly and assembly structure 30 includes a support cover plate 32 and a collar 35. The support cover plate 32 is located below the cover plate 11 and is arranged parallel to the cover plate 11, and the support cover plate 32 is fixedly connected to the cover plate 11. The top surface of the support cover plate 32 is provided with a second groove 33, and the bottom surface is provided with an elongated sliding opening 34 that passes through the second groove 33, forming an annular support surface at the junction of the second groove 33 and the elongated sliding opening 34. The collar 35 is fitted onto the opening of the collection bucket 20, and the collar 35 slides along the length direction of the elongated sliding opening 34 on the annular support surface.

[0053] The supporting cover plate 32 is connected to the cover plate 11. The second groove 33 and the elongated sliding opening 34 on the supporting cover plate 32 form an annular support surface, which can support both ends of the collar 35, thereby ensuring that the collection bucket 20 can only slide in the horizontal direction. When it slides to the bottom of the sampling valve 40 outlet, the droplets are collected. When it slides to a position away from the sampling valve 40 outlet, sampling can be performed. This structure is easy to operate and highly practical.

[0054] The elongated sliding opening 34 mainly ensures that the collection bucket 20 can pass through and that the collection bucket 20 can slide horizontally.

[0055] In this embodiment, the cover plate 11 and the supporting cover plate 32 can be bolted together, and both can be rectangular plates of the same specifications. The corresponding second groove 33 is a rectangular groove, and the corresponding elongated sliding opening 34 is a rectangular opening. The length of the elongated sliding opening 34 is less than the length of the second groove 33, and the width is less than the width of the second groove 33. The opening is located in one side area of ​​the cover plate 11, which can relatively shorten the length of the cover plate 11 and the supporting cover plate 32.

[0056] In some embodiments, the collar 35 may be adopted as follows: Figure 3 The structure shown. See also Figure 3 The collar 35 and the collection bucket 20 are integrally formed, or it can be understood that the collar 35 is the flange at the top of the collection bucket 20, which is convenient for manufacturing.

[0057] In this embodiment, the collection bucket 20 can be a circular cylinder or a square cylinder.

[0058] Example 3:

[0059] In some embodiments, the fixing structure 10 described above can be as follows: Figures 7 to 9 The structure shown. See also Figures 7 to 9 The fixed structure 10 includes a cover plate 11, which is a circular plate and is fixedly mounted on the sampling valve 40 in the horizontal direction. The central hole on the cover plate 11 is a through hole.

[0060] The cover plate 11 can ensure a fixed connection with the sampling valve 40. The outlet of the sampling valve 40 passes through its central hole, which can ensure an integral connection between the cover plate 11 and the sampling valve 40. At the same time, it can also ensure that the dripping droplets are located below the cover plate 11, and the circular cover plate 11 is easy to manufacture.

[0061] In some embodiments, the above-described disassembly and assembly structure 30 may adopt the following... Figures 7 to 9 The structure shown. See also Figures 7 to 9The disassembly and assembly structure 30 includes a fixed circular plate 36, a collar 35, a pull rod 37, and a hook 38. The fixed circular plate 36 is located above the cover plate 11 and is arranged parallel to and spaced apart from the cover plate 11. The fixed circular plate 36 and the cover plate 11 are collinear. The outer edge of the fixed circular plate 36 has at least two notches 39, and each notch 39 is arranged annularly spaced around the axis of the fixed circular plate 36. The collar 35 is fitted onto the opening of the collection bucket 20. There are multiple pull rods 37, each located outside the fixed circular plate 36 and corresponding to each notch 39. Each pull rod 37 is arranged vertically, with its bottom end fixedly connected to the collar 35, and its top end having a hook 38 extending horizontally towards the axis of the fixed circular plate 36.

[0062] The collar 35 facilitates the installation of the pull rods 37 and can be an outwardly bent flange at the top of the collection tank 20. When the disassembly structure 30 is in the droplet collection state, the top of the collection tank 20 is in sealed contact with the bottom surface of the cover plate 11, and the hooks 38 at the top of each pull rod 37 pass through the corresponding notches 39 and are engaged with the top surface of the fixed circular plate 36 after rotation. When sampling is required, simply rotate each pull rod 37 through the collection tank 20 so that each hook 38 corresponds to its respective notch 39. Then, the collection tank 20 can be moved downwards so that each hook 38 is engaged on the cover plate 11, exposing the sampling port, at which point sampling can be performed. Conversely, the collection tank 20 is sealed to the cover plate 11.

[0063] This structure is easy to manufacture and simple to operate, and it can also ensure the collection of droplets dripping from the outlet of sampling valve 40, making it highly practical.

[0064] The notch 39 mentioned in this embodiment can be a long opening that is radially arranged along the fixed circular plate 36 and extends to the outer edge.

[0065] In some embodiments, the aforementioned fixed circular plate 36 may be adopted as follows: Figures 7 to 9 The structure shown. See also Figures 7 to 9 The diameter of the fixed circular plate 36 is greater than or equal to the diameter of the cover plate 11. This structure can prevent interference between the tie rods 37 and the cover plate 11, and can also reduce the diameter of the cover plate 11.

[0066] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
