[0022] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0024] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0025] Reference Figures 1 to 7 A single-point mooring oil hose connection flange includes a flange 10 and an venting mechanism 20. The flange 10 is located at the end of the oil hose. The venting mechanism 20 is located on the flange 10. The venting mechanism 20 enables rapid venting.

[0026] Understandably, the exhaust mechanism 20 allows for direct exhaust without loosening the bolts on the flange 10, changing the way volatile gases are emitted and improving construction efficiency and safety.

[0027] Reference Figure 1 The exhaust mechanism 20 includes an exhaust port 21 and an exhaust column 22. The exhaust port 21 is located on the flange 10. The exhaust port 21 is located radially from the flange 10. The exhaust column 22 is screwed into the exhaust port 21. By rotating the exhaust column 22, volatile gases can be discharged from the exhaust port 21.

[0028] Reference Figures 1 to 7 The exhaust port 21 includes an internally threaded section 211 and a first smooth section 212. The exhaust column 22 includes an externally threaded section 221, a second smooth section 222, an operating section 223, and an exhaust channel 224. The outer diameter of the second smooth section 222 is equal to the inner diameter of the first smooth section 212. The internally threaded section 211 and the externally threaded section 221 mate with each other. The length of the second smooth section 222 is greater than the length of the first smooth section 212. One end of the exhaust channel 224 is located on the side of the second smooth section 222, and the other end is located at the end of the operating section 223. The operating section 223 has a regular polygonal cross-section. Rotating the operating section 223 causes the second smooth section 222 to slide along the first smooth section 212.

[0029] Understandably, after the wrench is engaged in the operating section 223, turning the wrench causes the exhaust column 22 to rotate. At this time, with the cooperation of the internal thread section 211 and the external thread section 221, the second smooth section 222 extends out and enters the inside of the flange 10. At this time, the exhaust channel 224 connects the inside and outside of the flange 10, thus achieving exhaust.

[0030] When venting is not required, after locking the wrench on the operating section 223, turn the wrench in the opposite direction to drive the vent column 22 to rotate. At this time, with the cooperation of the internal thread section 211 and the external thread section 221, the second smooth section 222 retracts into the first smooth section 212, and the opening of the vent passage 224 is sealed by the inner wall of the first smooth section 212.

[0031] It should be noted that in the embodiments of this utility model, the threads of the internal thread section 211 and the external thread section 221 are both pipe threads (threads are not shown in the figure).

[0032] It is worth noting that in some embodiments of this utility model, the surface roughness of the first smooth segment 212 and the second smooth segment 222 is not greater than 1.6 μm.

[0033] It is worth noting that a high surface finish can prevent excessive friction between the first smooth section 212 and the second smooth section 222.

[0034] It is worth noting that in some embodiments of this utility model, the cross-section of the operating segment 223 is a regular quadrilateral.

[0035] It is worth noting that in some embodiments of this utility model, the cross-section of the operating segment 223 is a regular hexagon.

[0036] Reference Figure 1 There are several exhaust mechanisms 20, and these exhaust mechanisms 20 are evenly distributed around the flange 10.

[0037] Reference Figure 1 The exhaust mechanism 20 also includes a locking nut 23, which is screwed onto the external thread section 221 and abuts against the outer circle of the flange 10. The locking nut 23 can lock the exhaust column 22.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
