Description

Technical Field

[0001] This invention belongs to the field of cooler pressure testing technology, specifically relating to rapid pressure testing equipment and sealing method for marine plate coolers. Background Technology

[0002] Plate coolers are a new type of high-efficiency heat exchanger composed of a series of corrugated metal plates stacked together. Thin rectangular channels are formed between the plates, facilitating heat exchange. Marine plate coolers, as core equipment in ship propulsion systems, refrigeration systems, and heat exchange circuits, are constructed from a series of corrugated metal plates. The thin rectangular channels between the plates enable efficient heat exchange, and their sealing performance and pressure resistance directly determine the stability of the ship's power output, navigation safety, and equipment lifespan. During operation, the air pressure inside the cooler needs to be monitored. Cooler pressure testing devices are typically used to monitor the cooler's pressure and ensure normal operation. These devices use sensors to monitor the cooler's pressure in real time and issue alarms or take appropriate control measures when the pressure is abnormal.

[0003] The existing Chinese utility model patent with patent publication number CN222166415U discloses a heat exchanger pressure testing fixture, which is a pressure testing fixture specially designed for a specific plate heat exchanger. The two sets of sealing plate components have a simple structure design. The two sets of sealing plate components are assembled together to seal and seal the inlet and outlet positions of the medium channel in the heat exchanger core. The pressure testing mechanism checks the sealing performance and pressure bearing capacity of the medium channel, and simulates the reliability and durability in actual use. The fixture assembly and pressure testing operation are very simple and effective. However, in actual use, there are still the following shortcomings: From a practical point of view, the two ends of the plate cooler are connected to the external testing pipeline through flange connection, which is relatively cumbersome during testing, thus affecting the testing efficiency; moreover, it lacks real-time pressure monitoring and automatic pressure relief functions, resulting in a high risk of overpressure.

[0004] Therefore, there is a need for rapid pressure testing equipment and sealing methods for marine plate coolers to solve the problems of existing technologies that connect to external testing pipelines via flanges, which is cumbersome during testing and lacks real-time pressure monitoring and automatic pressure relief functions, resulting in a high risk of overpressure. Summary of the Invention

[0005] The purpose of this invention is to provide a rapid pressure testing device and sealing method for marine plate coolers, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a rapid pressure testing device and sealing method for marine plate coolers, comprising a plate cooler body and connecting pipes, wherein the connecting pipes are symmetrically arranged on the right side of the plate cooler body, and a sealing mechanism is provided on the right side of the connecting pipes, wherein a sealing pipe is fixedly connected inside the sealing mechanism, and the sealing mechanism is used to fix the connection between the connecting pipes and the sealing pipes and ensure the sealing performance of the connection, and a driving mechanism is provided on one side of the sealing mechanism.

[0007] It should be noted in the solution that a pressure gauge is installed on the outside of the upper sealed pipe, and one end of the upper sealed pipe is connected to the connecting pipe, and the other end is connected to the external pressure testing pump. The lower sealed pipe is equipped with a pressure relief mechanism for releasing pressure after the pressure test is completed.

[0008] It is worth noting that the sealing mechanism consists of a fixed top ring, a fixed slide rod, a fixed bottom ring, a movable ring, a connecting seat, a rotating rod, an L-shaped connecting rod, a clamping block, a limiting block, and an anti-slip layer. The fixed slide rod is symmetrically fixedly connected to the right side of the fixed top ring, the fixed bottom ring is fixedly connected to the right side of the fixed slide rod, and the movable ring is slidably connected to the outside of the fixed slide rod and is located between the fixed top ring and the fixed bottom ring.

[0009] Furthermore, it should be noted that the sealing pipe is fixedly connected to the fixed top ring and the fixed bottom ring respectively, and passes through the moving ring. A sealing ring is fixedly connected to the left end of the sealing pipe, and the sealing ring is used to ensure the sealing of the connection between the connecting pipe and the sealing pipe.

[0010] In a preferred embodiment, the connecting seat is symmetrically and fixedly connected to the outer periphery of the moving ring, one end of the rotating rod is rotatably connected to the inside of the connecting seat, the short side of the L-shaped connecting rod is rotatably connected to the other end of the rotating rod, the clamping block is fixedly connected to one side of the long side of the L-shaped connecting rod, the limiting block is fixedly connected to the back of the clamping block, and the left side of the fixed top ring is provided with a limiting groove for the limiting block to slide.

[0011] In a preferred embodiment, the clamping block has an anti-slip layer inside, the clamping block is set in a right angle shape, and the distance from the right side of the clamping block to the sealing pipe is adapted to the thickness of the connecting plate of the connecting pipe. The anti-slip layer is made of rubber.

[0012] In a preferred embodiment, the drive mechanism comprises a fixed plate, a rotating lead screw, a connecting plate, and a handle. The fixed plate is fixedly connected to the top of the fixed bottom ring, the rotating lead screw is threadedly connected to the inside of the fixed plate, the connecting plate is rotatably connected to the left end of the rotating lead screw, the connecting plate is fixedly connected to the top of the moving ring, and the handle is fixedly connected to the right end of the rotating lead screw.

[0013] In a preferred embodiment, the pressure relief mechanism comprises an adjusting block, a long rod, a squeezing block, and a pressure relief valve. The squeezing block is slidably connected to the inside of the sealed pipe, the long rod is fixedly connected to the left side of the squeezing block, the adjusting block is fixedly connected to the left end of the long rod, the adjusting block is slidably connected to the inner wall of the sealed pipe, a pressure groove is formed at the upper part of the inside of the sealed pipe, the adjusting block is located directly below the pressure groove, a pressure relief valve is fixedly connected to the upper part of the sealed pipe, a pressure indicator is fixedly connected to the side of the pressure relief valve, and the inside of the pressure relief valve is connected to the inner wall of the pressure groove.

[0014] A rapid pressure testing and sealing method for marine plate coolers, used to implement the aforementioned rapid pressure testing equipment for marine plate coolers, includes the following steps:

[0015] Step 1: Fit the sealing ring of the sealing pipe with the port of the connecting pipe, and ensure that the connecting plate and the clamping block are aligned and matched to prepare for the connection of the connecting pipe and the sealing pipe.

[0016] Step 2: Turn the handle clockwise and push the moving ring to slide, which will cause the clamping block to clamp the connecting plate. The anti-slip layer will fit tightly against the surface of the connecting plate, forming a double seal with the sealing ring to maintain the clamping state.

[0017] Step 3: Start the pressure testing pump and observe whether there is any leakage at the sealing parts through the pressure test gauge; during the pressure test, observe the pressure inside the sealed pipeline in real time through the pressure display of the pressure relief mechanism, and it is strictly forbidden to test the pressure beyond the limit.

[0018] Step 4: After the pressure test is completed, the pressure relief valve will automatically release pressure to normal pressure. Turn the handle counterclockwise to loosen the clamping block and separate the sealed pipe from the connecting pipe.

[0019] Compared with the prior art, the rapid pressure testing equipment and sealing method for marine plate coolers provided by the present invention have at least the following beneficial effects:

[0020] (1) The right-angle clamping block of the sealing mechanism is precisely matched with the thickness of the connecting plate of the connecting pipe. With the anti-slip layer of rubber material, the connecting plate of the connecting pipe can be stably clamped and fixed, effectively preventing the connection from loosening under the turbulence of the ship. At the same time, the sealing ring at the end of the sealing pipe can further fill the connection gap between the connecting pipe and the sealing pipe. The double sealing structure greatly reduces the risk of leakage of the test medium and ensures that the test data is true and reliable.

[0021] (2) Through the sealing mechanism and driving mechanism, the operator can control the rotation direction and number of turns of the rotating screw by rotating the handle, thereby accurately adjusting the displacement of the moving ring and realizing the quick clamping and loosening of the clamping block on the connecting pipe; the whole process does not require the use of complex auxiliary tools, greatly shortening the equipment docking time before pressure test and the disassembly time after pressure test, and significantly improving the pressure test efficiency of marine plate coolers.

[0022] (3) The pressure inside the plate cooler can be monitored in real time during the pressure test by the set equipment and the pressure test gauge, which makes it easy for the operator to keep track of the pressure test progress; at the same time, the pressure relief mechanism is equipped with a pressure display and a pressure relief valve. When the pressure in the sealed pipeline reaches the specified threshold, the squeezing block drives the adjusting block to move, triggering the pressure relief valve to open automatically to relieve pressure, avoiding damage to the plate cooler body due to overpressure, ensuring the safety of the pressure test operation and reducing equipment maintenance costs.

[0029] The present invention will be further described below with reference to embodiments.

[0030] Reference Figure 1-5As shown, the present invention provides a rapid pressure testing device for marine plate coolers, including a plate cooler body 1 and a connecting pipe 2. The connecting pipe 2 is symmetrically arranged on the right side of the plate cooler body 1. A sealing mechanism 3 is provided on the right side of the connecting pipe 2. A sealing pipe 5 is fixedly connected inside the sealing mechanism 3. The sealing mechanism 3 is used to fix the connection between the connecting pipe 2 and the sealing pipe 5 and ensure the sealing of the connection. A driving mechanism 4 is provided on one side of the sealing mechanism 3.

[0031] Reference Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that a pressure gauge 6 is installed on the outside of the upper sealing pipe 5, and one end of the upper sealing pipe 5 is connected to the connecting pipe 2, while the other end is connected to the external pressure testing pump. The lower sealing pipe 5 is equipped with a pressure relief mechanism 7, which is used for pressure release after the pressure test is completed.

[0032] Reference Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the sealing mechanism 3 consists of a fixed top ring 301, a fixed slide rod 302, a fixed bottom ring 303, a moving ring 304, a connecting seat 305, a rotating rod 306, an L-shaped connecting rod 307, a clamping block 308, a limiting block 309, and an anti-slip layer 310. The fixed slide rod 302 is symmetrically fixedly connected to the right side of the fixed top ring 301. The fixed bottom ring 303 is fixedly connected to the right side of the fixed slide rod 302. The moving ring 304 is slidably connected to the outside of the fixed slide rod 302 and is located between the fixed top ring 301 and the fixed bottom ring 303. The sealing pipe 5 is fixedly connected to the fixed top ring 301 and the fixed bottom ring 303 respectively, and passes through the moving ring 304. A sealing ring 8 is fixedly connected to the left end of the sealing pipe 5. The sealing ring 8 is used to ensure the sealing of the connection between the connecting pipe 2 and the sealing pipe 5.

[0033] Reference Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the connecting seat 305 is symmetrically and fixedly connected to the outer periphery of the moving ring 304, one end of the rotating rod 306 is rotatably connected to the inside of the connecting seat 305, the short side of the L-shaped connecting rod 307 is rotatably connected to the other end of the rotating rod 306, the clamping block 308 is fixedly connected to one side of the long side of the L-shaped connecting rod 307, the limiting block 309 is fixedly connected to the back of the clamping block 308, and the left side of the fixed top ring 301 is provided with a limiting groove 311 for the limiting block 309 to slide.

[0034] The connecting seat 305 provides a pivot point for the rotating rod 306, allowing the rotating rod 306 to rotate around the connecting seat 305. This converts the up-and-down movement of the moving ring 304 into the rotational movement of the rotating rod 306. As the rotating rod 306 rotates, the L-shaped connecting rod 307 rotates around its connection point with the rotating rod 306, thereby adjusting the position of the clamping block 308 and enabling the clamping block 308 to accurately fix the connecting disc of the connecting pipe 2.

[0035] Reference Figure 2 , Figure 3 and Figure 5 As shown, it is worth noting that the clamping block 308 has an anti-slip layer 310 inside. The clamping block 308 is set in a right angle shape, and the distance from the right side of the clamping block 308 to the sealing pipe 5 is adapted to the thickness of the connecting plate of the connecting pipe 2. The anti-slip layer 310 is made of rubber.

[0036] The right-angled clamping block 308 can be used to clamp and fix the connecting disc of the connecting pipe 2, and the anti-slip layer 310 can be used to further improve the clamping force and fastness.

[0037] Reference Figure 2 , Figure 3 and Figure 5 As shown, it is worth noting that the drive mechanism 4 consists of a fixed plate 401, a rotating screw 402, a connecting plate 403, and a handle 404. The fixed plate 401 is fixedly connected to the top of the fixed bottom ring 303, the rotating screw 402 is threadedly connected to the inside of the fixed plate 401, the connecting plate 403 is rotatably connected to the left end of the rotating screw 402, the connecting plate 403 is fixedly connected to the top of the moving ring 304, and the handle 404 is fixedly connected to the right end of the rotating screw 402.

[0038] By operating the handle 404, the operator can easily control the rotation direction and number of turns of the rotating screw 402, thereby achieving precise adjustment of the position of the moving ring 304, and thus completing the clamping and releasing operation of the connecting pipe 2.

[0039] Reference Figure 2 , Figure 3 and Figure 5As shown, it is worth noting that the pressure relief mechanism 7 consists of an adjusting block 701, a long rod 702, a squeezing block 703, and a pressure relief valve 705. The squeezing block 703 is slidably connected to the inside of the sealed pipe 5. The long rod 702 is fixedly connected to the left side of the squeezing block 703. The adjusting block 701 is fixedly connected to the left end of the long rod 702. The adjusting block 701 is slidably connected to the inner wall of the sealed pipe 5. A pressure groove 704 is provided at the top inside the sealed pipe 5. The adjusting block 701 is located directly below the pressure groove 704. The pressure relief valve 705 is fixedly connected to the top of the sealed pipe 5. A pressure indicator is fixedly connected to the side of the pressure relief valve 705. The inside of the pressure relief valve 705 is connected to the inner wall of the pressure groove 704.

[0040] When the air pressure inside the sealed pipe 5 increases, the squeezing block 703 will slide to the right inside the sealed pipe 5. The pressure value is displayed by the pressure display. When the adjusting block 701 is not completely located at the bottom of the pressure groove 704, the pressure value reaches the specified value, and the pressure relief valve 705 will open to relieve pressure on the plate cooler body 1.

[0041] Furthermore, this solution provides a rapid pressure testing and sealing method for marine plate coolers, using the rapid pressure testing equipment for marine plate coolers described above, including the following steps:

[0042] Step 1: Align the fixing top ring 301 of the sealing mechanism 3 with the connecting end of the connecting pipe 2, and push the sealing mechanism as a whole so that the sealing ring 8 at the left end of the sealing pipe 5 fits tightly with the port of the connecting pipe 2. Ensure that the connecting plate and the clamping block 308 of the sealing mechanism 3 are aligned and matched, that is, the thickness direction of the connecting plate is consistent with the distance from the right side of the clamping block 308 to the sealing pipe 5, so as to prepare for subsequent clamping and sealing.

[0043] Step 2: Operate the handle 404 of the drive mechanism 4, rotate the handle 404 clockwise, and drive the rotating screw 402 to rotate to the left around the fixed plate 401; since the left end of the rotating screw 402 is fixedly connected to the moving ring 304 through the connecting plate 403, and the moving ring 304 is slidably connected to the outside of the fixed slide rod 302, when the rotating screw 402 rotates, it will push the moving ring 304 to slide smoothly along the fixed slide rod 302 towards the fixed top ring 301;

[0044] During the sliding process of the moving ring 304, the connecting seats 305 around its outer perimeter move synchronously, causing the rotating rod 306 to rotate around the connecting seat 305, which in turn drives the L-shaped connecting rod 307 to rotate around the connection point with the rotating rod 306; at this time, the long side of the L-shaped connecting rod 307 drives the clamping block 308 to move towards the connecting plate of the connecting pipe 2, and the limiting block 309 slides along the limiting groove 311 of the fixed top ring 301 to ensure the accurate movement trajectory of the clamping block 308;

[0045] Continue rotating the handle 404 until the right-angled inner side of the clamping block 308 is fully clamped to the connecting plate of the connecting pipe 2, and the anti-slip layer 310 on the inner side of the clamping block 308 is in close contact with the surface of the connecting plate; at this time, stop rotating the handle 404, and the thread self-locking characteristic of the rotating screw 402 can fix the position of the moving ring 304, so that the clamping block 308 remains in a stable clamping state, forming a double sealing structure with the sealing ring 8, and achieving a reliable seal between the connecting pipe 2 and the sealing pipe 5;

[0046] Step 3: Start the external pressure test pump and inject the test medium into the plate cooler body 1 and the sealing pipe 5. Monitor the pressure change in real time through the pressure test gauge 6 of the upper sealing pipe 5, and at the same time observe whether there is any leakage at the connection between the connecting pipe 2 and the sealing pipe 5 and the mating surface of the sealing ring 8.

[0047] If an abnormal drop in pressure or local leakage is found, immediately stop the pressure test pump. After depressurizing through the pressure relief mechanism 7, rotate the handle 404 counterclockwise to loosen the clamping block 308. Check whether the sealing ring 8 and the anti-slip layer 310 are damaged. After the problem is solved, repeat steps one to two.

[0048] During the pressure test, the internal pressure of the sealed pipeline 5 is observed in real time through the pressure display of the pressure relief mechanism 7 to ensure that the pressure does not exceed the rated test pressure value of the equipment and to avoid overpressure damage to the sealing structure.

[0049] Step 4: After the pressure test is completed, stop the pressure test pump and open the pressure relief mechanism 7: When the air pressure in the sealed pipe 5 rises to the specified threshold, the squeezing block 703 slides to the right along the sealed pipe 5, driving the long rod 702 and the adjusting block 701 to move. When the adjusting block 701 disengages from the bottom of the pressure tank 704, the pressure relief valve 705 opens automatically, and the test medium in the plate cooler body 1 and the sealed pipe 5 is discharged through the pressure relief valve 705. The pressure display value gradually drops to normal pressure.

[0050] After confirming that the system is completely depressurized, rotate the handle 404 of the drive mechanism 4 counterclockwise, causing the rotating screw 402 to rotate to the right, pulling the moving ring 304 to slide along the fixed slide bar 302 away from the fixed top ring 301; during the sliding of the moving ring 304, the rotating rod 306 and the L-shaped connecting rod 307 move in the opposite direction, the clamping block 308 disengages from the connecting plate of the connecting pipe 2, and the limiting block 309 resets along the limiting groove 311; pull the sealing mechanism 3 as a whole to separate the sealing pipe 5 from the connecting pipe 2, completing the sealing release operation.

[0051] In summary, the advantages of this invention are as follows: the right-angled clamping block 308 of the sealing mechanism 3 is precisely matched with the thickness of the connecting plate of the connecting pipe, and with the rubber anti-slip layer 310, a stable clamping and fixing effect can be formed on the connecting plate of the connecting pipe, effectively preventing the connection from loosening under the turbulence of ship navigation; at the same time, the sealing ring 8 at the end of the sealing pipe can further fill the connection gap between the connecting pipe and the sealing pipe. The double sealing structure greatly reduces the risk of leakage of the test medium and ensures that the test pressure data is true and reliable.

[0052] With the sealing mechanism 3 and the driving mechanism 4 in place, the operator can control the rotation direction and number of turns of the rotating screw 402 by rotating the handle 404, thereby precisely adjusting the displacement of the moving ring 304 and realizing the quick clamping and releasing operation of the clamping block 308 on the connecting pipe 2. The whole process does not require the use of complex auxiliary tools, which greatly shortens the equipment docking time before pressure testing and the disassembly time after pressure testing, and significantly improves the pressure testing efficiency of marine plate coolers.

[0053] The pressure inside the plate cooler 1 can be monitored in real time during the pressure test using the pressure test gauge 6, allowing operators to keep track of the test progress. Meanwhile, the pressure relief mechanism 7 is equipped with a pressure display and a pressure relief valve 705. When the pressure inside the sealed pipeline reaches the specified threshold, the squeezing block 703 moves the adjusting block 701, triggering the pressure relief valve 705 to automatically open and release pressure, preventing damage to the plate cooler body 1 due to overpressure, ensuring the safety of the pressure test operation, and reducing equipment maintenance costs.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
