Description

Technical Field

[0001] This utility model relates to the field of natural gas storage tank technology, and in particular to a safety pressure relief protection device for natural gas storage tanks. Background Technology

[0002] Natural gas, as a clean and efficient energy source, relies on natural gas storage tanks for stable turnover during its storage process. These tanks are widely used in gas stations, industrial production, and urban gas reserves. Natural gas storage tanks must withstand high internal pressure (normal operating pressure 0.8-6.4 MPa) for extended periods, while also facing the dual impacts of external environmental factors (such as impacts and temperature fluctuations) and the characteristics of the medium (such as impurities and condensates). Therefore, the need for safety protection is extremely urgent.

[0003] Natural gas storage tanks are core equipment in the natural gas storage process and must withstand high pressure inside the tank for a long time. To avoid overpressure inside the tank due to temperature fluctuations, medium expansion, etc., most of them are equipped with pressure relief valves as core pressure relief components. These valves can promptly discharge excess gaseous natural gas from the tank and prevent the pressure from exceeding the safety limit, which could lead to tank deformation, leakage, or even explosion. They are key devices to ensure the safe operation of storage tanks.

[0004] Most existing pressure relief valves are directly exposed to the outside environment. Rain, snow, dust, salt spray, and other external factors come into direct contact with the valve body and valve core, which not only easily leads to corrosion of metal parts and wear of sealing surfaces, significantly shortening the service life of the pressure relief valve, but also makes the pressure relief valve exposed to the outside environment susceptible to impact from other objects, increasing the maintenance cost of the equipment. Therefore, we propose a safety pressure relief protection device for natural gas storage tanks to solve the above problems. Utility Model Content

[0005] The main purpose of this utility model is to provide a safety pressure relief protection device for natural gas storage tanks, which can effectively solve the above problems.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A safety pressure relief protection device for a natural gas storage tank includes a movable base plate, a frame fixedly connected to the top of the movable base plate, a storage tank mounted on the top of the movable base plate, a pressure relief valve mounted on the front of the storage tank, and a protective component disposed above the frame.

[0007] Preferably, the protective assembly includes two rotating frames, with a fixing plate installed on the top of the frame. The outer surfaces of the back of the two rotating frames are rotatably connected to the inner wall of the frame. The two rotating frames can be combined into a complete protective frame, and the storage tank is located inside the formed protective frame.

[0008] Preferably, protective shells are installed at the ends of the two storage tanks that are close to each other on the front side. Both protective shells are snapped onto the outer surface of the pressure relief valve. The two protective shells are in contact with each other and can form a shell covering the pressure relief valve.

[0009] Preferably, a connecting plate is installed on the front outer surface of both storage tanks, and both connecting plates are located directly below the protective shell on the same side.

[0010] Preferably, both connecting plates have square holes on their outer surfaces, with the square hole on the left being higher than the square hole on the right.

[0011] Preferably, a fixing rod is fixedly connected to the inner wall of each of the two square holes, and a sliding plate is slidably connected to the outer surface of each of the two fixing rods. The outer surface of each of the two sliding plates is slidably connected to the inner wall of the square hole on the same side.

[0012] Preferably, each of the two sliding plates has a handle installed at the ends that are far apart from each other, and the ends of the two sliding plates that are far away from the connecting plate on the same side are both inclined, and the two sliding plates are interlocked with each other.

[0013] Preferably, springs are sleeved on the outer surfaces of both fixing rods. The top of the spring on the left is fixedly connected to the inner wall of the square hole on the same side, the bottom of the spring on the left is fixedly connected to the top of the sliding plate on the same side, the bottom of the spring on the right is fixedly connected to the inner wall of the square hole on the same side, and the top of the spring on the right is fixedly connected to the bottom of the sliding plate on the same side.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model incorporates a protective component, specifically by rotating two rotating frames to drive the corresponding protective shells to rotate. When the rotating frames rotate at a certain angle, the two protective shells can form a complete shell, which can prevent external rain, snow, dust, salt spray, etc. from directly contacting the valve body and valve core of the pressure relief valve. This not only slows down the rate of corrosion of the valve body and valve core and wear of the sealing surface, thus extending the service life of the pressure relief valve, but also prevents the pressure relief valve from being directly impacted by external objects, reducing the maintenance cost of the device.

[0015] 2. This utility model, by setting a sliding plate and a spring, specifically, when it is necessary to open the two rotating frames, by pulling the two handles to move them away from each other, the corresponding sliding plate is moved to slide, which can quickly and conveniently release the restriction on the two rotating frames without complicated disassembly steps. The spring sliding plate can quickly release the restriction on the rotating frames, allowing the rotating frames to be opened directly, which greatly shortens the operation time for pressure relief valve inspection, maintenance or emergency situations, and avoids delays in fault handling due to cumbersome operation.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Example 1, as Figure 1-5 As shown, a safety pressure relief protection device for a natural gas storage tank includes a movable base plate 1, a frame 11 fixedly connected to the top of the movable base plate 1, a storage tank 12 installed on the top of the movable base plate 1, a pressure relief valve 13 installed on the front of the storage tank 12, and a protective component 2 provided above the frame 11.

[0020] Specifically, in order to achieve the purpose of protecting the pressure relief valve, see [reference needed]. Figure 2 and Figure 3 In this embodiment, the protective component 2 includes two rotating frames 22, and a fixing plate 21 is installed on the top of the frame 11. The outer back surfaces of the two rotating frames 22 are rotatably connected to the inner wall of the frame 11. The two rotating frames 22 can be combined into a complete protective frame, and the storage tank 12 is located inside the formed protective frame.

[0021] Further reading Figure 3 In this embodiment, protective shells 23 are installed on the front sides of the two storage tanks 12 that are close to each other. The two protective shells 23 are snapped onto the outer surface of the pressure relief valve 13. The two protective shells 23 are in contact with each other and can form a shell covering the pressure relief valve 13.

[0022] Further reading Figure 3 In this embodiment, a connecting plate 24 is installed on the outer surface of the front of both storage tanks 12, and both connecting plates 24 are located directly below the protective shell 23 on the same side.

[0023] During implementation, after the storage tank 12 is installed on top of the movable base plate 1, the two rotating frames 22 are rotated to rotate within the inner wall of the fixed plate 21. When the rotating frames 22 rotate, they will drive the corresponding protective shells 23 to rotate. When the rotating frames 22 rotate at a certain angle, they can drive the protective shells 23 to engage with the outer surface of the pressure relief valve 13. At the same time, the two protective shells 23 can come into contact together to form a complete shell. The formed shell can protect the pressure relief valve 13 inside, preventing external rain, snow, dust, salt spray, etc. from directly contacting the valve body and valve core. This not only slows down the rate of corrosion of the valve body and valve core and wear of the sealing surface, extending the service life of the pressure relief valve 13, but also prevents the pressure relief valve 13 from being directly impacted by external objects, reducing the maintenance cost of the device.

[0024] Example 2: This example is based on Example 1, with the addition of a sliding plate and a spring.

[0025] Specifically, in order to achieve the goal of quickly and easily removing the restrictions on the two rotating frames, refer to... Figure 5 In this embodiment, square holes are provided on the outer surfaces of both connecting plates 24, with the square hole on the left being higher than the square hole on the right.

[0026] Further reading Figure 5 In this embodiment, a fixing rod 241 is fixedly connected to the inner wall of each of the two square holes, and a sliding plate 242 is slidably connected to the outer surface of each of the two fixing rods 241. The outer surface of each of the two sliding plates 242 is slidably connected to the inner wall of the square hole on the same side.

[0027] Further reading Figure 5 In this embodiment, each of the two sliding plates 242 is equipped with a handle 244 at one end that is far away from each other, and the ends of the two sliding plates 242 that are far away from the connecting plate 24 on the same side are both set with an inclined surface, and the two sliding plates 242 are interlocked with each other.

[0028] Further reading Figure 5 In this embodiment, springs 243 are sleeved on the outer surfaces of both fixing rods 241. The top of the spring 243 on the left side is fixedly connected to the inner wall of the square hole on the same side, and the bottom of the spring 243 on the left side is fixedly connected to the top of the sliding plate 242 on the same side. The bottom of the spring 243 on the right side is fixedly connected to the inner wall of the square hole on the same side, and the top of the spring 243 on the right side is fixedly connected to the bottom of the sliding plate 242 on the same side.

[0029] During implementation, the rotating frame 22 rotates, which in turn drives the corresponding connecting plate 24 to rotate. When the connecting plate 24 rotates, it drives the sliding plate 242 to rotate. When the two sliding plates 242 rotate a certain angle, their surfaces will come into contact with each other. Since the ends of the two sliding plates 242 that come into contact with each other are both set with inclined surfaces, as the sliding plate 242 continues to rotate, the sliding plate 242 will slide on the outer surface of the corresponding connecting plate fixing rod 241. When the sliding plate 242 slides, it will compress the spring 243 and cause it to deform. When the two rotating frames 22 have finished rotating, the two sliding plates 242 will move closer to each other due to the deformation of the spring 243, so that the two sliding plates 242 are locked together, which can prevent the two rotating frames 22 from rotating randomly.

[0030] When it is necessary to open the two rotating brackets 22, the two handles 244 are pulled away from each other. When the handles 244 move, they will drive the corresponding sliding plates 242 to slide on the outer surface of the fixed rod 241. When the sliding plates 242 slide, they will compress the spring 243. After the two sliding plates 242 have moved a certain distance, they can separate, thereby quickly and conveniently releasing the restriction on the two rotating brackets 22. There is no need for complicated disassembly steps. The restriction on the rotating brackets 22 can be quickly released by the spring 243 and the sliding plates 242, allowing the rotating brackets 22 to be opened directly. This greatly shortens the operation time for the pressure relief valve inspection, maintenance or emergency, and avoids delays in fault handling due to cumbersome operation.

[0031] The working principle of this utility model is as follows: After the storage tank 12 is installed on the top of the movable base plate 1, the two rotating frames 22 are rotated to drive them to rotate in the inner wall of the fixed plate 21. When the rotating frames 22 rotate, they will drive the corresponding protective shells 23 to rotate. When the rotating frames 22 rotate at a certain angle, they can drive the protective shells 23 to engage with the outer surface of the pressure relief valve 13. At the same time, the two protective shells 23 can contact each other to form a complete shell. The formed shell can protect the pressure relief valve 13 inside and prevent external rain, snow, dust, salt spray and other external objects from directly contacting the valve body and valve core. This not only slows down the rate of corrosion of the valve body and valve core and wear of the sealing surface, thus extending the service life of the pressure relief valve 13, but also prevents the pressure relief valve 13 from being directly impacted by external objects, thus reducing the maintenance cost of the device.

[0032] As the rotating frame 22 rotates, it drives the corresponding connecting plate 24 to rotate. When the connecting plate 24 rotates, it drives the sliding plate 242 to rotate. When the two sliding plates 242 rotate a certain angle, their surfaces will come into contact with each other. Since the ends of the two sliding plates 242 that come into contact with each other are both set with inclined surfaces, as the sliding plate 242 continues to rotate, the sliding plate 242 will slide on the outer surface of the corresponding connecting plate fixing rod 241. When the sliding plate 242 slides, it will compress the spring 243 and cause it to deform. When the two rotating frames 22 have finished rotating, the two sliding plates 242 will move closer to each other due to the deformation of the spring 243, so that the two sliding plates 242 are locked together, which can prevent the two rotating frames 22 from rotating randomly.

[0033] When it is necessary to open the two rotating brackets 22, the two handles 244 are pulled away from each other. When the handles 244 move, they will drive the corresponding sliding plates 242 to slide on the outer surface of the fixed rod 241. When the sliding plates 242 slide, they will compress the spring 243. After the two sliding plates 242 have moved a certain distance, they can separate, thereby quickly and conveniently releasing the restriction on the two rotating brackets 22. There is no need for complicated disassembly steps. The restriction on the rotating brackets 22 can be quickly released by the spring 243 and the sliding plates 242, allowing the rotating brackets 22 to be opened directly. This greatly shortens the operation time for the pressure relief valve inspection, maintenance or emergency, and avoids delays in fault handling due to cumbersome operation.
