Description

Technical Field

[0001] The invention relates to the technical field of pressure vessels, in particular to a pressure vessel with an anti-leakage structure. Background Art

[0002] Pressure vessels refer to closed equipment that contains gas or liquid and bears a certain pressure. Pressure vessels are widely used and play an important role in many sectors such as industry, civil industry, military industry, and many fields of scientific research. Among them, the most used are in the chemical industry and petrochemical industry. The pressure vessels used in the petrochemical industry alone account for about 50% of the total number of pressure vessels. In the chemical and petrochemical fields, pressure vessels are mainly used in heat transfer, mass transfer, reaction and other process processes, as well as storage and transportation of pressurized gas or liquefied gas.

[0003] Based on the above, the inventors have found that the existing pressure vessels with anti-leakage structures mainly have the following deficiencies. For example, when the existing pressure vessels are in use, the pressure inside the pressure vessels may gradually increase. However, the pressure inside each pressure vessel has a limit value. When the pressure exceeds the limit value, the pressure vessel may leak, thereby causing damage to the pressure vessel. Summary of the invention

[0004] In view of the above problems, the present invention provides a pressure vessel with a leakage-proof structure.

[0005] In order to achieve the above-mentioned object, the present invention is realized by the following technical scheme: a pressure vessel with an anti-leakage structure, which comprises a pressure vessel and an anti-leakage structure, wherein the top of the pressure vessel is connected to the anti-leakage structure, and the left end face of the pressure vessel is connected to the liquid inlet pipe, and the liquid outlet pipe is arranged on the right end face of the pressure vessel; the anti-leakage structure is provided with a regulating device and a pressure reducing tank, the regulating device is fixedly mounted on the top end face of the pressure vessel, and the top end face of the regulating device is connected to the pressure reducing tank, the left and right end faces of the pressure reducing tank are provided with a pressure relief valve, and the pressure gauge is fixedly connected to the right end face of the pressure reducing tank; The adjusting device is provided with a mounting seat, a fixing seat, and an adjusting structure. The mounting seat is fixedly mounted on the top end surface of the pressure vessel, and a servo motor is provided on the top left side of the mounting seat to drive a threaded rod to rotate, and the threaded rod is threadedly matched with the fixing seat, the adjusting structure is fixedly connected to the inside of the mounting seat, and the adjusting structure is plug-connected with the fixing seat, and the connecting pipe is provided on the top end surface of the mounting seat and communicates with the bottom of the pressure reducing tank; The fixing seat is provided with a fixing plate, a sealing block is provided in the middle of the bottom of the fixing plate, the bottom two sides of the fixing plate are fixedly connected with the reset spring, the reset spring is connected with the connecting plate, and the connecting plate is threadedly connected with the threaded rod, the limiting rod is provided with two fixedly connected to the upper and lower ends of the inside of the mounting seat respectively, and the limiting rod penetrates the end surface of the fixing seat and the adjusting structure, and the connecting plate can be clamped on the end surface of the limiting rod and move up and down; The adjustment structure includes a support plate and an oil pipe, wherein the oil pipe is provided in the middle of the support plate, and through grooves are provided on both sides of the support plate, wherein the through grooves are movably matched with the limit rod, and a thread groove is provided on the left side of the support plate, wherein the thread groove is threadably matched with the thread rod; When the liquid pressure in the pressure container reaches the limit, the liquid in the adjustment structure pushes the sealing block upward, and the elasticity of the reset spring can increase the pressure on the inside of the oil pipe. The servo motor can drive the threaded rod to rotate and move downward in coordination with the connecting plate thread, so that the liquid needs a greater pressure inside the mounting seat to push the sealing block open and flow outward to relieve pressure. When the servo motor drives the threaded rod to rotate and move upward in coordination with the connecting plate thread, the liquid only needs a smaller pressure inside the mounting seat to push the sealing block open, and then the pressure of automatic pressure relief can be adjusted by adjusting the position of the connecting plate. The automatic pressure relief operation can be achieved by adjusting the position of the connecting plate to set the container pressure required for pressure relief.

[0006] The bottom side end surface of the sealing block is provided with an inclined surface inclined at 15 degrees, and the outer end surface of the sealing block is wrapped with a rubber layer.

[0007] Furthermore, the inclined surface at the bottom of the sealing block can assist in aligning the end surface of the adjusting structure for insertion, and the rubber layer can enhance the sealing performance between the sealing block and the adjusting structure.

[0008] The inner end surface of the oil passage pipe is provided with a rubber pad, and the end surfaces of the through groove and the threaded pipe are sealed by the rubber pad.

[0009] Furthermore, the through groove and the threaded pipe are sealed by a rubber pad to prevent leakage of liquid.

[0010] The pressure container is provided with a partition plate and a through groove. Two partition plates are provided and the partition plates are respectively arranged on both sides of the interior of the pressure container. The through groove is located at the bottom end surface of the partition plate.

[0011] Furthermore, by dividing the pressure vessel into three parts through a partition plate, the pressure vessel can allow liquid to flow in the through groove during transportation, which can reduce the flow area of ​​the liquid in the pressure vessel, thereby reducing the inertia generated by liquid transportation and facilitating the transportation of liquid in the pressure vessel.

[0012] The pressure vessel is provided with a pressure relief pipe, a transverse pipe and a pipe head inside. The pressure relief pipe is vertically arranged on the bottom end surface of the anti-leakage structure. The transverse pipe is fixedly connected to the bottom end surface of the pressure relief pipe, and the pressure relief pipe passes through the end surfaces of two partition plates. The pipe head is provided with three ones respectively arranged on both sides and in the middle of the transverse pipe.

[0013] Furthermore, the three pipe heads can be used to evenly distribute the pressure on the liquid in the pressure vessel, allowing the liquid to flow out evenly.

[0014] The liquid outlet pipe is provided with a connecting pipe and a liquid extraction pipe. The connecting pipe is connected to the right side of the pressure vessel. Three liquid extraction pipes are provided and the liquid extraction pipes are vertically connected to the bottom end face of the connecting pipe. The bottom end face of the liquid extraction pipe is 5 cm away from the inner bottom end of the pressure vessel.

[0015] Furthermore, by setting the distance between the extraction tube and the bottom end of the pressure vessel to 5 cm, the extraction tube can fully drain the liquid in the pressure vessel without affecting the speed at which the extraction tube extracts the liquid. Beneficial Effects

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. When the liquid pressure in the pressure vessel reaches a set value, the present invention allows the liquid to move upward against the sealing block in the regulating structure, allowing the liquid to flow into the pressure reducing tank and then flow out through the liquid outlet pipe for collection, thereby maintaining the stability of the internal pressure of the pressure vessel and avoiding overpressure damage caused by excessive internal pressure of the pressure vessel.

[0017] 2. The present invention utilizes a servo motor to drive the connecting plate to move up and down through a threaded rod, and adjusts the positional relationship between the reset spring and the fixing seat, so that the liquid in the mounting seat needs to have different pressures to push the fixing seat upward to achieve the pressure relief effect. The pressure value of the liquid to be relieved can be controlled by adjusting the position of the connecting plate, so that the liquid in the pressure container can automatically relieve pressure when it reaches the set pressure value.

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0026] Example 1: Please refer to Figure 1-Figure 6 , the specific embodiments of the present invention are as follows: Its structure includes a pressure vessel 1 and an anti-leakage structure 2. The top of the pressure vessel 1 is connected to the anti-leakage structure 2, and the left end face of the pressure vessel 1 is connected to the liquid inlet pipe 3, and the liquid outlet pipe 4 is arranged on the right end face of the pressure vessel 1; the anti-leakage structure 2 is provided with a regulating device 21 and a pressure reducing tank 22, the regulating device 21 is fixedly installed on the top end face of the pressure vessel 1, and the top end face of the regulating device 21 is connected to the pressure reducing tank 22, the left and right end faces of the pressure reducing tank 22 are provided with a pressure relief valve 23, and a pressure gauge 24 is fixedly connected to the right end face of the pressure reducing tank 22; The adjusting device 21 is provided with a mounting seat 211, a fixing seat 213, and an adjusting structure 216. The mounting seat 211 is fixedly mounted on the top end surface of the pressure vessel 1, and a servo motor 214 is provided on the top left side of the mounting seat 211 to drive a threaded rod 215 to rotate, and the threaded rod 215 is threadedly matched with the fixing seat 213, and the adjusting structure 216 is fixedly connected to the inside of the mounting seat 211, and the adjusting structure 216 is plug-connected with the fixing seat 213, and the connecting pipe 212 is provided on the top end surface of the mounting seat 211 and communicates with the bottom of the pressure reducing tank 22; The fixing seat 213 is provided with a fixing plate 2131, and a sealing block 2132 is provided in the middle of the bottom of the fixing plate 2131. The two sides of the bottom of the fixing plate 2131 are fixedly connected with the return spring 2135. The return spring 21 is connected with the connecting plate 2136, and the connecting plate 2136 is threadedly connected with the threaded rod 215. The limiting rod 2134 is provided with two upper and lower ends fixedly connected to the inner side of the mounting seat 211, and the limiting rod 2134 penetrates the end surface of the fixing seat 213 and the adjusting structure 216, and the connecting plate 2136 can be clamped on the end surface of the limiting rod 2134 and move up and down; The adjustment structure 216 includes a support plate 2161 and an oil pipe 2163. The oil pipe 2163 is provided in the middle of the support plate 2161, and through grooves 2162 are provided on both sides of the support plate 2161. The through grooves 2162 are movably matched with the limiting rod 2135. A threaded groove 2165 is provided on the left side of the support plate 2161, and the threaded groove 2165 is threadedly matched with the threaded rod 215. When the liquid pressure in the pressure container 1 reaches the limit, the liquid in the adjustment structure 216 pushes the sealing block 2132 to move upward, and the elasticity of the return spring 21 can increase the pressure on the inside of the oil pipe 2163. The servo motor 214 can drive the threaded rod 215 to rotate and cooperate with the connecting plate 2136 to move downward, so that the liquid needs a larger pressure inside the mounting seat 211 to push the sealing block 2132 open and flow outward to relieve pressure. When the servo motor 214 drives the threaded rod 215 to rotate and cooperate with the connecting plate 2136 to move upward, the liquid only needs a smaller pressure inside the mounting seat 211 to push the sealing block 2132 open, and then the pressure of automatic pressure relief can be adjusted by adjusting the position of the connecting plate 2136. The automatic pressure relief operation can be achieved by adjusting the position of the connecting plate 2136 to set the container pressure required for pressure relief.

[0027] Based on the above embodiment, the specific working principle is as follows: when the liquid pressure in the pressure vessel reaches the limit, the liquid is allowed to push the sealing block in the adjustment structure and move upward, so that the liquid can flow into the pressure reducing tank 22, and then flow outward through the liquid outlet pipe 4 for collection, so as to maintain the stability of the internal pressure of the pressure vessel 1 and avoid the pressure vessel 1 from being damaged due to excessive pressure. Then, the servo motor 214 is used to drive the threaded rod 215 to rotate and move downward in coordination with the thread of the connecting plate 2136, so that the liquid inside the mounting seat 211 needs a greater pressure to push the sealing block 2132 open and flow outward for pressure relief. When the servo motor 214 drives the threaded rod 215 to rotate and move upward in coordination with the thread of the connecting plate 2136, the liquid inside the mounting seat 211 only needs a smaller pressure to push the sealing block 2132 open, and then the pressure of automatic pressure relief can be adjusted by adjusting the position of the connecting plate 2136. The automatic pressure relief operation can be achieved by adjusting the position of the connecting plate 2136 to set the container pressure required for pressure relief.

[0028] Example 2: Please refer to Figure 2 , Figure 5 , Figure 6 , the specific embodiments of the present invention are as follows: The bottom side end surface of the sealing block 2132 is provided with a slope with an inclination of 15 degrees, and the outer end surface of the sealing block 2132 is wrapped with a rubber layer 2133.

[0029] The inclined surface at the bottom of the sealing block 2132 can assist in aligning the end surface of the adjusting structure 216 for insertion, and the rubber layer 2133 can enhance the sealing between the sealing block 2132 and the adjusting structure 216 .

[0030] The inner end surface of the oil passage pipe 2163 is provided with a rubber pad 2164 , and the end surfaces of the through groove 2162 and the threaded tube 2165 are both sealed by the rubber pad 2164 .

[0031] The through groove 2162 and the threaded tube 2165 are sealed by the rubber pad 2164 to prevent liquid leakage.

[0032] The pressure container 1 is provided with a partition plate 12 and a through groove 13 . Two partition plates 12 are provided, and the partition plates 12 are respectively arranged on both sides of the interior of the pressure container 1 . The through groove 13 is located at the bottom end surface of the partition plate 12 .

[0033] The pressure vessel 1 is divided into three parts by the partition plate 12, so that the liquid in the pressure vessel 1 can flow in the through groove 13 during transportation, which can reduce the flow area of ​​the liquid in the pressure vessel 1, thereby reducing the inertia generated by the liquid transportation, making it easier to transport the liquid in the pressure vessel 1.

[0034] The pressure vessel 1 is provided with a pressure relief pipe 11, a transverse pipe 14, and a pipe head 15. The pressure relief pipe 11 is vertically arranged on the bottom end surface of the anti-leakage structure 2, the transverse pipe 14 is fixedly connected to the bottom end surface of the pressure relief pipe 11, and the pressure relief pipe 11 passes through the end surfaces of two partition plates 12. The pipe head 15 is provided with three ones respectively arranged on both sides and in the middle of the transverse pipe 14.

[0035] The three pipe heads 15 can be used to evenly divide the pressure of the liquid in the pressure container 1 so that the liquid can flow out evenly.

Three liquid extraction pipes 42 are provided, and the liquid extraction pipes 42 are vertically connected to the bottom end surface of the connecting pipe 41. The bottom end surface of the liquid extraction pipe 42 is 5 cm away from the inner bottom end of the pressure vessel 1.

[0037] By setting the distance between the liquid extraction pipe 42 and the bottom end of the pressure vessel 1 to 5 cm, the liquid extraction pipe 42 can fully drain the liquid in the pressure vessel 1 without affecting the speed at which the liquid extraction pipe 42 extracts the liquid.

[0038] Based on the above embodiment, the specific working principle is as follows: the inclined surface at the bottom of the sealing block 2132 can be used to assist in aligning the end face of the adjustment structure 216 for insertion, and the rubber layer 2133 can strengthen the sealing between the sealing block 2132 and the adjustment structure 216, and then the rubber cushion 2164 is used to seal the through groove 2162 and the threaded tube 2165 to prevent liquid leakage, and then the partition plate 12 is used to divide the pressure vessel 1 into three parts, so that the pressure vessel 1 can allow the liquid to flow in the through groove 13 during transportation, which can reduce the flow area of ​​the liquid in the pressure vessel 1, and then reduce the inertia generated by the liquid transportation, which is convenient for the transportation of the liquid in the pressure vessel 1, and finally, the distance between the liquid extraction tube 42 and the bottom end of the pressure vessel 1 is set to 5 cm, so that the liquid extraction tube 42 can fully drain the liquid in the pressure vessel 1 without affecting the speed of the liquid extraction tube 42.
