DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-Figure 4 The utility model provides an emergency breakaway valve for hose operation, comprising a conveying assembly A 1 and a conveying assembly B 2, wherein the conveying assembly A 1 and the conveying assembly B 2 are respectively mounted with a closing assembly A 3 and a closing assembly B 4, and the conveying assembly A 1 and the conveying assembly B 2 are connected by a connecting assembly 5;

[0026] The A closing component 3 includes an A cross member 31, an A spring 32, an A closing plate 33, and an A sliding rod 34. The A cross member 31 is mounted on the A conveying component 1. A sliding hole is formed on the A cross member 31. The A sliding rod 34 is disposed in the sliding hole. The A closing plate 33 is mounted on the A sliding rod 34. A plurality of A springs 32 are provided, and the plurality of A springs 32 are mounted between the A cross member 31 and the A closing plate 33.

[0027] The B closing assembly 4 includes a B cross piece 41, a B spring 42, a B sliding rod 44 and a B sliding rod 44. The B cross piece 41 is mounted on the B conveying assembly 2. A sliding hole is opened on the B cross piece 41. The B sliding rod 44 is arranged in the sliding hole. The B sliding rod 44 is mounted on the B sliding rod 44. A plurality of B springs 42 are provided, and the plurality of B springs 42 are mounted between the B cross piece 41 and the B sliding rod 44.

[0028] The A closing component 3 and the B closing component 4 are symmetrically arranged, and the ends of the A sliding rod 34 and the B sliding rod 44 are in contact and pressed against each other.

[0029] Specifically, when transporting liquid hazardous chemicals or oil products, in order to avoid the displacement of the ship due to extreme adverse weather, misoperation, etc., which may break the hose or process pipeline and cause leakage of oil products or chemicals, a conveying component A 1 and a conveying component B 2 may be set at the hose, and the conveying component A 1 and the conveying component B 2 may be connected by a connecting component 5. At this time, by connecting the conveying component A 1 and the conveying component B 2, the closing component A 3 and the closing component B 4 may be squeezed against each other, so that the conveying component A 1 and the conveying component B 2 may be connected together. However, when severe weather occurs, which causes the displacement of the ship, the tension on both sides of the hose increases. At this time, the connecting component 5 cannot stably connect the conveying component A 1 and the conveying component B 2, so that the conveying component A 1 and the conveying component B 2 may be separated from each other. During the separation period, the closing component A 3 and the closing component B 4 will respectively seal the conveying component A 1 and the conveying component B 2, thereby preventing leakage of liquid hazardous chemicals or oil products. When the severe weather ends and re-transportation is required, the conveying component A 1 and the conveying component B 2 may be connected again.

[0030] Furthermore, during use, when the A conveying component 1 and the B conveying component 2 are connected, the A sliding rod 34 and the B sliding rod 44 squeeze each other, so that the A closing plate 33 and the A sliding rod 34 as well as the B closing plate 43 and the B sliding rod 44 can move relative to each other. At this time, the A conveying component 1 and the B conveying component 2 are together, and when the A conveying component 1 and the B conveying component 2 are disconnected, the A closing plate 33 and the B closing plate 43 move under the elastic force of the A spring 32 and the B spring 42 respectively. At this time, the A closing plate 33 and the B closing plate 43 will respectively close the ends of the A ring member 16 and the B ring member 25, thereby preventing leakage of liquid hazardous chemicals or oil products.

[0031] In this embodiment, the A conveying component 1 includes an A conveying pipe 12, an A mounting ring 13, a circular hollow pipe 14, a square hollow pipe 15 and an A ring member 16. The A mounting ring 13 is installed on the A conveying pipe 12, the circular hollow pipe 14 and the square hollow pipe 15 are both installed on the circumferential surface of the A mounting ring 13, and the A ring member 16 is installed on the A mounting ring 13.

[0032] Specifically, during actual use, liquid hazardous chemicals or oil products can be transported through the A delivery pipe 12. During this period, in order to enable the A delivery pipe 12 and the B delivery pipe 22 to be stably connected, an A mounting ring 13 can be set on the A delivery pipe 12, and a round hollow tube 14 and a square hollow tube 15 are designed on the A mounting ring 13. In order to enable the A closing plate 33 to open and close the A delivery component 1 during movement, an A ring member 16 is set on the A mounting ring 13.

[0033] In this embodiment, the A cross member 31 is installed inside the A delivery pipe 12, and the A closing plate 33 is arranged inside the A ring member 16. The A ring member 16 is arranged to have a semi-conical structure.

[0034] Specifically, the A-ring member 16 is set to a semi-conical structure with an open upper end. At this time, when the A-closing plate 33 moves downward, a gap will be created between the A-closing plate 33 and the A-ring member 16, so that liquid hazardous chemicals or oil products can flow. After the A-closing plate 33 moves upward, the end of the A-ring member 16 can be closed, thereby preventing the liquid hazardous chemicals or oil products from flowing.

[0035] In this embodiment, the A conveying component 1 also includes an A flange 11, a connecting piece 17, a fixing ring 18 and an A sealing ring 19. The A flange 11 is installed on the A conveying pipe 12. There are multiple connecting pieces 17, and the multiple connecting pieces 17 are all installed on the A mounting ring 13. The fixing ring 18 is provided on multiple connecting pieces 17, and the A sealing ring 19 is installed at the port of the A ring member 16.

[0036] Specifically, when connecting the A conveying pipe 12 to the hose, an A flange 11 can be set at the end of the A conveying pipe 12 and connected to the hose through the A flange 11. In order to facilitate the stable setting of the A conveying component 1, a connecting piece 17 can be set on the A mounting ring 13, and a fixing ring 18 can be set on the connecting piece 17. By fixing the fixing ring 18, the A conveying component 1 can be stably set. During the specific conveying period, in order to avoid a gap between the A conveying component 1 and the B conveying component 2, an A sealing ring 19 can be set on the A ring member 16.

[0037] In this embodiment, the B conveying component 2 includes a B conveying pipe 22, a B mounting ring 23, a B ring member 25, a circular guide member 26 and a square guide member 27.

The circular guide member 26 and the square guide member 27 are both installed on the extension portion; the circular guide member 26 and the square guide member 27 are respectively connected to the circular hollow tube 14 and the square hollow tube 15.

[0038] Specifically, during transportation, the transportation can be completed by connecting the A delivery tube 12 and the B delivery tube 22 together. When in use, a B mounting ring 23 is set on the B delivery tube 22, and a B ring member 25 is set on the B mounting ring 23. A circular guide member 26 and a square guide member 27 are set on the extension of the B ring member 25. By inserting the circular guide member 26 and the square guide member 27 into the inside of the circular hollow tube 14 and the square hollow tube 15, the A delivery component 1 and the B delivery component 2 can be preliminarily connected.

[0039] In this embodiment, the B cross member 41 is installed inside the B delivery pipe 22, and the B closing plate 43 is arranged inside the B ring member 25. The B ring member 25 is arranged to be a semi-conical structure.

[0040] Specifically, similar to the above, in order to enable the conveying operation to be performed when the B closing plate 43 moves downward, the B ring member 25 is configured as a semi-conical structure.

[0041] In this embodiment, the B conveying component 2 also includes a B flange 21, a limiter 24 and a B sealing ring 28. A mounting groove is provided on the B mounting ring 23. The limiter 24 includes a mounting portion and a rotating portion. The mounting portion is arranged in the mounting groove, and the rotating portion is arranged above the A mounting ring 13. The B sealing ring 28 is arranged on the B annular member 25, and the B sealing ring 28 and the A sealing ring 19, and the B flange 21 are installed on the B conveying pipe 22.

[0042] Specifically, during use, in order to prevent the A conveying component 1 and the B conveying component 2 from colliding with each other due to the displacement of the ship, a limiter 24 can be set on the B mounting ring 23. The limiter 24 can prevent the distance between the A mounting ring 13 and the B mounting ring 23 from being too close, thereby avoiding collision. In order to avoid leakage during transportation, a B sealing ring 28 is set on the B ring member 25, so that it cooperates and engages with the A sealing ring 19 to avoid leakage.

[0043] In this embodiment, the connecting assembly 5 includes a ring 51, a rod 52, a C spring 53 and a clamp mechanism 54. There are multiple rods 52, and the multiple rods 52 are all installed on the A mounting ring 13. The ring 51 is mounted on the multiple rods 52. There are multiple C springs 53, and the multiple C springs 53 are respectively mounted on the multiple rods 52, and the multiple C springs 53 are all arranged between the A mounting ring 13 and the ring 51. The clamp mechanism 54 is installed on the extension part, and the ring 51 is arranged on the clamp mechanism 54.

[0044] Specifically, when connecting the A conveying component 1 and the B conveying component 2, a sleeve rod 52 can be set on the A mounting ring 13 and the sleeve ring 51 can be sleeved on the sleeve rod 52, the C spring 53 can be set between the A mounting ring 13 and the sleeve ring 51, and the clamp mechanism 54 can be set on the B ring member 25. Since the clamp mechanism 54 can change its diameter, at this time, the sleeve ring 51 is sleeved on the clamp mechanism 54, and the diameter of the clamp mechanism 54 is changed, so that the clamp mechanism 54 can be interference connected with the sleeve ring 51, thereby enabling the A conveying component 1 and the B conveying component 2 to be connected.

[0045] The working principle and usage process of the present invention are as follows: when transporting liquid hazardous chemicals and oil products on a ship, in order to avoid displacement of the ship due to extreme adverse weather, misoperation, etc., and breaking of the hose or process pipeline, a conveying component A 1 and a conveying component B 2 are set on the hose, and the conveying component A 1 and the conveying component B 2 are connected by a connecting component 5. Since the conveying component A 1 and the conveying component B 2 are respectively installed with the closing component A 3 and the closing component B 4, and since the conveying component A 1 and the conveying component B 2 are symmetrically arranged, the closing component A 3 and the closing component B 4 are also symmetrically arranged, and the two are squeezed against each other. Through the squeezing of the closing component A 3 and the closing component B 4, the conveying component A 1 and the conveying component B 2 can be connected, and then the conveying operation can be carried out. When the ship is displaced, the connecting component 5 cannot stably connect the conveying component A 1 and the conveying component B 2, which will cause the conveying component A 1 and the conveying component B 2 to separate. During the separation, the closing component A 3 and the closing component B 4 can seal the connection ends of the conveying component A 1 and the conveying component B 2, thereby avoiding leakage.

[0046] The electronic components and modules used in the content of this utility model can be parts commonly used in the market that can realize the specific functions of this case, and the specific models and sizes can be selected and adjusted according to actual needs.
