Description

Technical Field

[0001] The utility model relates to the technical field of pipelines, in particular to a pipeline with a jet flow prevention function. Background Art

[0002] Pipes with anti-spout function are widely used in many fields to transport liquids and gases, such as water, steam, gas, etc. These pipeline systems need to have high safety and reliability to ensure the smooth progress of the transportation process.

[0003] Anti-jet pipe is a special pipe designed to reduce or prevent the jet of liquid or gas in the pipeline system. It adopts a variety of technologies and devices to ensure that when abnormal pressure or leakage occurs in the pipeline system, it will not cause serious jet flow, thereby reducing the harm to personnel, equipment and the environment.

[0004] When a pipeline is transporting liquid, it may rupture due to various reasons such as aging and rust of the pipeline itself. Since the pipeline pressure control valve is located at the intersection of the node, it is impossible to close the inside of the pipeline and reduce the pressure in time after the pipeline ruptures, so a jet will form at the break of the pipeline, causing harm to the human body or the surrounding environment. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a pipeline with a jet prevention function, aiming to improve the problem that the pipeline pressure control valve is located at the node intersection, which leads to the inability to close and reduce the pressure inside the pipeline in time after the pipeline ruptures, thereby forming a jet at the broken part of the pipeline, causing harm to the human body or the surrounding environment.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a pipeline with anti-jet function, including a connecting pipe, a plurality of fixed support rods are fixedly connected to the middle part of the inner wall of the connecting pipe, a plurality of adjacent sides of the fixed support rods are fixedly connected to a fixed ring, a plurality of connecting columns are fixedly connected to the top of the fixed ring, a plurality of connecting columns are fixedly connected to the top of the drainage disk, a folding ring is fixedly connected to the bottom end of the fixed ring, a sealing plate is fixedly connected to the bottom end of the folding ring, a sealing disk is fixedly connected to the middle and lower part of the inner wall of the connecting pipe, a sealing groove is opened on the inner wall of the sealing disk, a suction hole is opened in the middle part of the top wall of the fixed ring, and a filtering device is arranged on the top end of the inner wall of the connecting pipe.

[0007] As a further description of the above technical solution:

[0008] The filtering device includes a fixing ring, the inner wall of the fixing ring is threadedly connected to a first filter valve, the inner wall of the first filter valve is fixedly connected to a coarse filter screen, the bottom end of the inner wall of the first filter valve is threadedly connected to a second filter valve, the inner wall of the second filter valve is provided with a ceramic filter element, the bottom end of the inner wall of the second filter valve is threadedly connected to a third filter valve, and the inner wall of the third filter valve is provided with an activated carbon filter element.

[0009] As a further description of the above technical solution:

[0010] A top pressure measuring device is fixedly connected to the top wall of the drainage plate, and a bottom pressure measuring device is fixedly connected to the bottom end of the blocking plate.

[0011] As a further description of the above technical solution:

[0012] A sealing ring is fixedly connected to the outer wall of the blocking plate.

[0013] As a further description of the above technical solution:

[0014] The inner wall of the coarse filter is provided with a plurality of holes.

[0015] As a further description of the above technical solution:

[0016] The top of the drainage disc adopts a conical design.

[0017] As a further description of the above technical solution:

[0018] The folding ring and the sealing disk are both symmetrically designed.

[0019] The utility model has the following beneficial effects:

[0020] 1. In the utility model, the fixed ring is fixed to the inner wall of the connecting pipe by a fixed support rod. When the connecting pipe is broken at a certain place, the pressure suddenly changes or the flow rate is too fast, which will cause the folding ring at the bottom to unfold, thereby ensuring that the sealing plate can fit tightly on the sealing groove of the sealing disk, and can quickly respond and close the pipeline. The suction hole in the middle of the top wall of the fixed ring can suck in a part of the fluid at the moment the connecting pipe is broken, so as to increase the speed of releasing and stretching the folding ring, thereby preventing the occurrence of the jet phenomenon.

[0021] 2. In the utility model, by using the fixing ring as the main structure of the entire filtering system, the first filter valve, the second filter valve and the third filter valve can be easily installed or removed by the threaded connection of the inner wall, and the purity of the fluid can be further improved. The threaded connection form allows each filter element to be easily disassembled and replaced, which greatly improves the maintenance convenience and service life of the device.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Reference Figure 1 and Figure 2 , the utility model provides an embodiment: a pipeline with anti-jet flow function, including a connecting pipe 1, a plurality of fixed support rods 3 are fixedly connected to the middle of the inner wall of the connecting pipe 1, and the adjacent sides of the plurality of fixed support rods 3 are fixedly connected to a fixed ring 4, the top of the fixed ring 4 is fixedly connected to a plurality of connecting columns 5, and the tops of the plurality of connecting columns 5 are fixedly connected to a drainage disk 6, the bottom end of the fixed ring 4 is fixedly connected to a folding ring 7, and the bottom end of the folding ring 7 is fixedly connected to a blocking plate 8, a blocking disk 9 is fixedly connected to the middle and lower part of the inner wall of the connecting pipe 1, and a blocking groove 10 is opened on the inner wall of the blocking disk 9, a suction hole 11 is opened in the middle of the top wall of the fixed ring 4, and a filtering device 2 is arranged on the top of the inner wall of the connecting pipe 1;

[0029] Specifically, the drainage plate 6 at the upper end of the connecting column 5 can guide the fluid to the surroundings to prevent the folding ring 7 from being expanded through the suction hole 11 due to the impact of the fluid under normal working conditions, causing the sealing plate 8 to fit with the sealing groove 10, affecting its normal use. When the fluid pressure in the pipeline increases and there is a possibility of a jet phenomenon, a pressure difference will be formed between the upper and lower ends of the sealing plate 9. Since the fixed circular ring 4 is fixed to the inner wall of the connecting pipe 1 by the fixed support rod 3, a sudden pressure change or excessive flow rate will cause the folding ring 7 at its bottom to expand, thereby ensuring that the sealing plate 8 can fit tightly on the sealing groove 10 of the sealing plate 9, and can respond quickly and close the pipeline. The suction hole 11 in the middle of the top wall of the fixed circular ring 4 can suck in a part of the fluid at the moment the connecting pipe 1 breaks, so as to increase the speed of releasing and stretching the folding ring 7. When the fluid attempts to pass through this part of the connecting pipe 1, the sealing plate 8 can effectively block the sealing groove 10.

[0030] Reference Figure 1 and Figure 3 The filter device 2 includes a fixing ring 201, the inner wall of the fixing ring 201 is threadedly connected with a first filter valve 202, the inner wall of the first filter valve 202 is fixedly connected with a coarse filter screen 203, the bottom end of the inner wall of the first filter valve 202 is threadedly connected with a second filter valve 204, the inner wall of the second filter valve 204 is provided with a ceramic filter element 205, the bottom end of the inner wall of the second filter valve 204 is threadedly connected with a third filter valve 206, and the inner wall of the third filter valve 206 is provided with an activated carbon filter element 207;

[0031] Specifically, the fixing ring 201 serves as the main structure of the entire filtering system. Through the threaded connection of the inner wall, the first filter valve 202 can be easily installed or disassembled. A coarse filter screen 203 is arranged inside the first filter valve 202, which is mainly used for preliminary filtering of large particles and impurities in the pipeline to prevent them from entering the subsequent filtering layer. At the bottom of the first filter valve 202, a second filter valve 204 is installed through a threaded connection. A ceramic filter element 205 is arranged inside the second filter valve 204. Through physical interception, chemical action and charge adsorption, the tiny particles, bacteria and other harmful substances in the fluid are further filtered out, so that the fluid is further purified. At the bottom of the second filter valve 204, a third filter valve 206 is installed again through a threaded connection. An activated carbon filter element 207 is arranged inside, which can effectively remove pollutants such as organic matter, odor and color in the fluid, and further improve the purity of the fluid.

[0032] Reference Figure 2 and Figure 3 The top wall of the drainage plate 6 is fixedly connected with a top pressure gauge 12, and the bottom end of the blocking plate 8 is fixedly connected with a bottom pressure gauge 13; the outer wall of the blocking plate 8 is fixedly connected with a sealing ring 14; the inner wall of the coarse filter 203 is provided with a plurality of holes 15;

[0033] Specifically, through the top pressure gauge 12 and the bottom pressure gauge 13, the pressure changes at the damaged and non-damaged parts of the pipeline can be monitored in real time. By measuring the pressure at different positions, the flow state of the fluid in the pipeline can be analyzed and potential problems can be discovered in time. The sealing ring 14 fixedly connected to the outer wall of the sealing plate 8 plays a sealing role, which can effectively prevent the fluid from leaking at the connection of the connecting pipe 1 and maintain the stable flow of the fluid in the connecting pipe 1. The multiple holes 15 opened on the inner wall of the coarse filter 203 allow the fluid to pass through while blocking large particles of impurities from entering the pipeline system.

[0034] Reference Figure 2 The top of the drainage disk 6 is conical in design; the folding ring 7 and the blocking disk 9 are both symmetrically designed;

[0035] Specifically, the top of the drainage plate 6 adopts a conical design to block the direct impact of the fluid on the suction hole 11, which can effectively prevent the folding ring 7 from maintaining its original state in a normal working environment. The folding ring 7 and the sealing plate 9 adopt a symmetrical design, which can play a symmetrical sealing and anti-spraying role in the connecting pipe 1 and ensure the tightness of the connection of the connecting pipe 1.

[0036] Working principle: the drainage plate 6 at the upper end of the connecting column 5 can guide the fluid to the surroundings to prevent the folding ring 7 from being impacted and expanded through the suction hole 11 due to the impact of the fluid under normal working environment, causing the sealing plate 8 to fit with the sealing groove 10, affecting its normal use. When the fluid pressure in the pipeline increases and there is a possibility of jet flow, a pressure difference will be formed between the upper and lower ends of the sealing plate 9. Since the fixed circular ring 4 is fixed to the inner wall of the connecting pipe 1 by the fixed support rod 3, a sudden pressure change or excessive flow rate will cause the folding ring 7 at its bottom to unfold, thereby ensuring that the sealing plate 8 can fit tightly on the sealing groove 10 of the sealing plate 9 and can respond quickly and close the pipeline. The suction hole 11 in the middle of the top wall of the fixed circular ring 4 can suck in a part of the fluid at the moment the connecting pipe 1 breaks, so as to increase the speed of releasing and stretching the folding ring 7. When the fluid tries to pass through this part of the connecting pipe 1, the sealing plate 8 can effectively block the sealing groove 10, thereby Prevent the occurrence of jet flow phenomenon, and the fixing ring 201 serves as the main structure of the entire filtering system. It can easily install or disassemble the first filter valve 202 through the threaded connection of the inner wall. A coarse filter screen 203 is arranged inside the first filter valve 202, which is mainly used for preliminary filtering of large particles and impurities in the pipeline to prevent them from entering the subsequent filtering layer. At the bottom of the first filter valve 202, a second filter valve 204 is installed through a threaded connection, and a ceramic filter element 205 is arranged inside it. Through physical interception, chemical action and charge adsorption, the tiny particles, bacteria and other harmful substances in the fluid are further filtered out, so that the fluid is further purified. At the bottom of the second filter valve 204, a third filter valve 206 is installed again through a threaded connection, and an activated carbon filter element 207 is arranged inside it, which can effectively remove organic matter, odor, color and other pollutants in the fluid, and further improve the purity of the fluid.
