Description

Technical Field

[0001] The utility model relates to the technical field of liquefied hydrocarbons, in particular to a water injection joint for a spherical tank area. Background Art

[0002] Liquefied hydrocarbon spherical tanks are used to store flammable and explosive hazardous media such as liquefied petroleum gas and liquefied natural gas, making their safety paramount. Water injection facilities play a crucial role in addressing leaks from the bottom of liquefied hydrocarbon spherical tanks. To address these issues, water injection facilities are essential, which plays a significant role in addressing leaks.

[0003] Fully pressurized storage tanks should implement water injection measures to prevent liquefied hydrocarbon leakage. These measures must meet water injection requirements and increase the amount of material used to prevent liquefied hydrocarbon leakage to ensure that water, rather than liquefied hydrocarbon, flows out of the leak. However, due to long-term disrepair or rust on the joints, water leakage is common at these joints. This not only delays the water injection of liquefied hydrocarbon spherical tanks but also easily leads to a waste of water resources. Therefore, in order to ensure the quality and quantity of water injection into liquefied hydrocarbon spherical tanks, there is an urgent need to provide a spherical tank area water injection joint that can effectively prevent water leakage, improve the safety of liquefied hydrocarbon spherical tanks, and protect people's lives and property. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the existing technology and provide a water injection joint for a spherical tank area, which can prevent water leakage and loss, and can also remind staff to carry out maintenance, thereby improving the safety of liquefied hydrocarbon spherical tanks and protecting people's lives and property.

[0005] The technical solution of the utility model is:

[0006] The spherical tank area water injection joint includes a pipe body, and connecting mechanisms are respectively provided at both ends of the pipe body to connect the pipe body and the water injection pipe together; a partition plate is provided in the pipe body, and the partition plate is obliquely arranged in the pipe body to divide the interior of the pipe body into two sections, and a through hole is provided on the partition plate, and a liftable sealing plate is provided above the through hole, and the sealing plate is adapted to the through hole; leak-proof rings are respectively provided at both ends of the pipe body and on the inner side of the connecting mechanism, and a water inlet trough with an opening facing the interior of the pipe body is provided in the leak-proof ring. After the pipe body is connected to the water injection pipe, the end of the water injection pipe covers the water inlet trough; a floating plate that can move up and down is provided in the water inlet trough, and a travel switch is provided at the top of the water inlet trough, and the travel switch is electrically connected to the controller.

[0007] Preferably, the sealing plate is connected to a lifting mechanism, and the lifting mechanism is provided on the pipeline body.

[0008] Preferably, the lifting mechanism adopts an electric push rod.

[0009] Preferably, limiting grooves are provided on both sides of the water inlet groove, and floating balls are provided on both sides of the floating plate. The floating balls are located in the limiting grooves, and the limiting grooves are provided with strip openings on the side facing the floating plate.

[0010] Preferably, the connection mechanism adopts a flange.

[0011] Preferably, a sealing ring is provided on the edge of the sealing plate.

[0012] Preferably, the outside of the pipe body is wrapped with a sponge layer.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] When the water filling joint of the utility model is used to fill the spherical tank with water, when a leak occurs at the joint, the water in the joint will leak into the water inlet groove of the leak-proof ring, and the floating plate in the water inlet groove rises as the leaking water level rises until the floating plate touches the travel switch. At this time, the sealing plate descends and blocks the through hole, so that the partition plate isolates the joint to prevent water leakage. At the same time, the controller sounds an alarm to remind the staff to carry out maintenance, thereby improving the safety of the liquefied hydrocarbon spherical tank and protecting people's lives and property.

[0019] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention.

[0020] Example 1

[0021] like Figure 1-2As shown, this embodiment provides a spherical tank area water injection joint, including a pipe body 1, with connecting mechanisms provided at both ends of the pipe body 1 to connect the pipe body 1 with the water injection pipe 2. Specifically, in this embodiment, the connecting mechanism can adopt a flange plate 7 to flange-connect the pipe body 1 with the water injection pipe 2 at both ends. A partition plate 3 is provided in the pipe body 1. The partition plate 3 is tiltedly arranged in the pipe body 1 to divide the interior of the pipe body 1 into two sections. A through hole 301 is provided on the partition plate 3. When water flows in the pipe body 1, it flows from one side of the partition plate 3 to the other side through the through hole 301. A liftable sealing plate 4 is provided above the through hole 301. The sealing plate 4 is adapted to the through hole 301. When water needs to flow normally in the pipe body 1, the sealing plate 4 can be raised to above the through hole 301. When the water flow needs to be cut off to close the water injection joint, the sealing plate 4 only needs to be lowered into the through hole 301 to block the through hole 301 to stop the water flow. Specifically, in this embodiment, the lifting and lowering of the sealing plate 4 can be achieved by the following structure: the sealing plate 4 is connected to a lifting mechanism, the lifting mechanism is arranged on the pipe body 1, and the lifting mechanism can adopt an electric push rod 6. The electric push rod 6 drives the sealing plate 4 to rise and fall, thereby realizing the opening and closing of the water injection joint.

[0022] At the same time, if Figure 1-3As shown, leak-proof rings 5 ​​are provided at both ends of the pipe body 1 and on the inner side of the connecting mechanism. A water inlet groove 501 opening toward the interior of the pipe body 1 is provided within the leak-proof ring 5. After the pipe body 1 is connected to the water injection pipe 2, the end of the water injection pipe 2 covers the water inlet groove 501. When the water injection pipe 2 is connected to both sides of the pipe body 1 via flanges 7, the end of the water injection pipe 2 extends into the pipe body 1 and covers the water inlet groove 501 of the leak-proof ring 5. When a leak occurs at the connection between the water injection joint and the water injection pipe 2, the leaked water will flow into the gap between the pipe body 1 and the water injection pipe 2 and ultimately into the water inlet groove 501 of the leak-proof ring 5. Furthermore, a floating plate 502 that can move up and down is provided within the water inlet groove 501. A limit switch 505 is provided at the top of the water inlet groove 501. The limit switch 505 is electrically connected to the controller. The up and down movement of the float plate 502 is achieved by the following structure: limit slots 503 are provided on both sides of the water inlet trough 501, and float balls 504 are provided on both sides of the float plate 502. The float balls 504 are located within the limit slots 503, and the limit slots 503 have a strip-shaped opening on the side facing the float plate 502. As more water leaks into the water inlet trough 501, more water enters the water inlet trough 501. The float plate 502 in the water inlet trough 501 rises with the increase in water volume until it reaches the top of the water inlet trough 501 and contacts the limit switch 505. The limit switch 505 then feeds a signal back to the controller. The controller controls the electric push rod 6 to drive the sealing plate 4 down to block the through hole 301, allowing the partition plate 3 to block the water flow and prevent water leakage. The controller also issues an alarm to alert staff to perform maintenance. In addition, to further achieve the desired leak prevention effect, a sealing ring 401 can be provided on the edge of the sealing plate 4 to ensure the sealing of the partition plate 3 after the sealing plate 4 blocks the through hole 301.

[0023] Example 2

[0024] On the basis of Example 1, the outside of the pipe body 1 is wrapped with a sponge layer 8, which can protect the pipe body 1 and prevent the pipe body 1 from being damaged by impact.
