Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of engineering slurry pipelines, in particular to a pressure relief device for slurry pipelines. Background Art
[0002] Slurry pipeline systems are commonly used to transport cement mortar at construction sites. The system consists of a pump, pipelines, joints, and related auxiliary equipment, which play an important role in the construction field. In concrete construction, cement slurry, as the main component of concrete, often needs to be efficiently and evenly transported to the construction site through the pipeline system and mixed with coarse aggregates and admixtures to form concrete; in grouting projects, such as tunnel lining, underground infrastructure construction, and foundation treatment, cement slurry is injected into the voids or cracks in the geotechnical structure through the pipeline system; in foundation reinforcement, the bearing capacity and stability of the foundations of existing buildings, roads, and bridges are improved by injecting cement slurry.
[0003] Currently, cement slurry conveying pipelines are generally made of plastic hoses composed of high molecular materials such as polyethylene (PE) or polyvinyl chloride (PVC). Quick joints are used for the connection between the hose and the high-pressure pump or the extension of pipe to pipe, such as clamp joints, flange joints, threaded joints, etc.
[0004] In the actual application of engineering slurry pipelines, whenever a unit sub-project at the site completes the task of transporting cement slurry, the pipeline system needs to be flexibly adjusted and quickly transferred to the next unit sub-project for continuous operation. In this process, the pump pipe inevitably undergoes multiple opening and closing cycles. Such frequent opening and closing operations not only cause significant fluctuations in the pressure inside the pipeline, but also generate extremely high peak pressures of cement slurry at the moment when the machine pump starts.
[0005] This instantaneous high-pressure phenomenon is very likely to exceed the pressure-bearing limit of the pipeline material. Especially for plastic hoses with relatively low strength, it directly threatens their structural integrity, resulting in the serious consequence of pipeline bursting. In addition, the sudden rise in instantaneous pressure also exerts huge stresses at the pipeline joints. These forces beyond the design expectations may cause the joints to loosen or even seal failure, leading to the leakage of cement slurry. For plastic hoses with strong flexibility, the impact of high pressure instantaneously may also cause adverse changes in their shape, further affecting the conveying efficiency and the overall stability of the system. At the same time, the acceleration of the flow rate of cement slurry under high-pressure conditions exacerbates the wear degree of the inner wall of the pipeline. In the long run, it will shorten the service life of the pipeline and increase the cost of maintenance and replacement. On the other hand, when the pipeline fixing brackets face instantaneous pressure impacts, they may also experience fixing failures, resulting in bracket displacement or damage, which not only affects the stability of the pipeline, but also poses a threat to the stable operation of the entire conveying system.
[0006] What is more serious is that the increase in instantaneous pressure will also trigger pressure fluctuations in the pipeline system. These fluctuations will spread to the entire system and may cause stress concentration on other pipeline sections or related equipment, thereby triggering a chain reaction and causing more extensive potential damage. Especially at the connection part, high pressure is often accompanied by the risk of sealing failure. Once the cement slurry leaks, it will not only reduce the construction quality, but also pollute the on-site environment, affecting construction safety and environmental sanitation. Utility Model Content
[0007] The utility model aims to provide a slurry pipeline pressure relief device to achieve the purpose of relieving cement slurry pressure and releasing part of the pipeline pressure.
[0008] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0009] A slurry pipeline pressure relief device comprises: a pressure relief chamber and a slurry pipeline, wherein the pressure relief chamber is unidirectionally connected to the slurry pipeline and the pressure relief chamber is located above the slurry pipeline; the pressure relief chamber comprises a first cavity, wherein the first cavity is used to store slurry; and a slurry discharge component, wherein one end of the slurry discharge component is connected to the slurry pipeline, and the other end passes through the pressure relief chamber into the first cavity and is connected to the first cavity.
[0010] According to the above technical means, the utility model is provided with a slurry discharge component on the slurry delivery pipeline. When instantaneous high pressure is generated in the slurry delivery pipeline due to the start-up of the machine pump or a sudden change in the delivery volume, the high-pressure mud can quickly pass through the slurry discharge component into the first cavity of the pressure relief chamber, thereby effectively alleviating the pressure peak in the pipeline, preventing the pipeline from bursting due to overpressure, and ensuring the safe operation of the pipeline system.
[0011] In the utility model, the pressure relief chamber is unidirectionally connected to the slurry delivery pipeline, that is, the mud in the pressure relief chamber can flow to the slurry delivery pipeline, but the mud in the slurry delivery pipeline cannot flow directly to the pressure relief chamber under normal operation, but only flows into the pressure relief chamber through the slurry relief component under specific conditions (such as overpressure), so that the mud in the pressure relief chamber can flow back to the slurry delivery pipeline when the pressure is reduced, thereby achieving the effect of economical utilization.
[0012] Furthermore, the slurry discharge assembly includes a stamping pipe and a slurry discharge valve, one end of the stamping pipe is connected to the slurry delivery pipeline, and the other end passes through the pressure relief chamber and is connected to the first cavity through the slurry discharge valve; the slurry discharge valve is movably installed at the other end of the stamping pipe, and the slurry discharge valve is configured to be able to seal the other end of the stamping pipe under the action of gravity, and to be able to be lifted up to release the seal under the impact of the mud flowing in the stamping pipe, so that the mud flowing in the stamping pipe can flow into the first cavity through the slurry discharge valve.
[0013] According to the above technical means, the slurry discharge valve can automatically seal the outlet of the punching pipe under the action of its own gravity, and will automatically open under the impact of mud. This automatic adjustment mechanism makes the pressure relief process without manual intervention, improving the automation and operation stability of the system. When the pressure in the slurry pipeline increases abnormally, the high-pressure mud can quickly impact the slurry discharge valve, causing it to lift and release the seal on the punching pipe, allowing the mud to quickly flow into the first cavity of the pressure relief chamber, thereby quickly reducing the pressure in the pipeline and effectively preventing the pipeline from being damaged due to overpressure.
[0014] Furthermore, the slurry drainage valve includes a second cavity and a slurry drainage channel, one end of the slurry drainage channel is connected to the side wall of the second cavity, and the other end is connected to the second cavity; the other end of the stamping pipe is installed in the second cavity, and under the action of gravity of the slurry drainage valve, the other end of the stamping pipe can abut against the top of the inner wall of the second cavity and cover one end of the slurry drainage channel; the slurry drainage valve is lifted under the impact of the mud flowing in the stamping pipe, and the other end of the stamping pipe can be away from the top of the inner wall of the second cavity and expose one end of the slurry drainage channel, so that the mud can flow into the first cavity through the slurry drainage channel.
[0015] According to the above technical means, the design of the slurry discharge valve enables the high-pressure mud to be quickly and effectively introduced into the pressure relief chamber when the pressure of the slurry pipeline increases abnormally, thereby protecting the pipeline system from overpressure damage. The slurry discharge valve is automatically triggered to open and close by the pressure of the mud, without manual intervention, which improves the automation and response speed of the system. The slurry discharge channel is closed under normal conditions and will only open when the pipeline pressure increases, effectively preventing accidental leakage and backflow of mud.
[0016] Furthermore, the slurry discharge channel includes a first pipe, a second pipe and a third pipe, one end of the first pipe, one end of the second pipe and one end of the third pipe are respectively connected to the side wall of the second cavity, and the other end of the first pipe, the other end of the second pipe and the other end of the third pipe are connected to the second cavity; and the first pipe, the second pipe and the third pipe are distributed in the vertical direction.
[0017] According to the above technical means, when the mud pressure in the slurry pipeline increases, the first pipeline is first used for preliminary pressure relief. If the pressure continues to rise, the pressure is further released through the second pipeline and the third pipeline. This graded pressure relief method can effectively avoid the impact and damage that may be caused by releasing too much pressure at one time. Through multi-stage pressure relief, it can be ensured that under high pressure, the mud can flow into the pressure relief tank smoothly and orderly, thereby reducing the safety risks such as pipeline rupture and leakage that may be caused by sudden pressure drop. The three-stage pressure relief design provides more pressure relief channels, so that under high pressure, the mud can flow into the pressure relief tank faster through multiple channels, thereby improving the pressure relief efficiency.
[0018] Furthermore, the slurry discharge valve also includes a first limit member, which is arranged in the second cavity; the stamping tube includes a second limit member, which is arranged at the other end of the stamping tube; the first limit member is adapted to the second limit member.
[0019] According to the above technical means, the first limit member cooperates with the second limit member to limit the slurry discharge valve from being separated from the other end of the stamping pipe during the continuous lifting process.
[0020] Furthermore, the pressure relief chamber also includes a shell and a discharge port, the first cavity is located in the shell, and the discharge port is arranged at the bottom of the shell and communicated with the first cavity.
[0021] According to the above technical means, the shell, as the main structure of the pressure relief chamber, not only provides a physical boundary for the first cavity, but also protects and isolates the mud inside it. This can prevent the mud from leaking out. Since the discharge port is located at the bottom of the shell, the mud can naturally settle at the bottom of the first cavity by gravity, which makes it possible to discharge the mud through the discharge port when it needs to be cleaned or discharged, optimize the flow path of the mud, and reduce the residence time of the mud in the pressure relief chamber, thereby improving the overall efficiency.
[0022] Furthermore, the pressure relief chamber also includes an inclined ladder, which is installed at the bottom of the first cavity so that the mud in the first cavity can flow to the discharge port.
[0023] According to the above-mentioned technical means, the inclined design of the inclined ladder enables the mud in the first cavity to flow naturally along the surface of the inclined ladder to the discharge port, thereby optimizing the flow path of the mud, reducing the residence time of the mud in the cavity, and improving the discharge efficiency of the mud. Through the guidance of the inclined ladder, solid particles and impurities in the mud are not easily deposited at the bottom of the first cavity, thereby reducing the difficulty of cleaning and maintenance.
[0024] Furthermore, it also includes a return pipe, one end of which is connected to the discharge port, and the other end of which is connected to the slurry delivery pipeline.
[0025] According to the above technical means, the mud discharged from the discharge port can be reintroduced into the mud delivery pipeline through the reflux pipe to realize the recycling of the mud, which helps to reduce the waste of mud and reduce production costs.
[0026] Furthermore, it also includes a one-way valve, which is installed on the return pipe to enable the pressure relief chamber to be connected to the slurry delivery pipeline in one direction.
[0027] According to the above technical means, the main function of the one-way valve is to ensure that the mud can only flow unidirectionally from the pressure relief chamber to the slurry conveying pipeline and cannot flow reversely. This effectively prevents the mud from flowing back from the slurry conveying pipeline to the pressure relief chamber during system pressure fluctuations or operational errors, ensuring the stable operation of the system. By restricting the flow direction of the mud, the one-way valve helps prevent the system pressure from getting out of control due to the reverse flow of the mud, reducing the risk of accidents caused by excessive pressure.
[0028] Furthermore, it also includes a pressure gauge, and the pressure gauge is installed on the pressure relief chamber.
[0029] According to the above technical means, the staff can judge whether the device is in a normal working state by checking the reading of the pressure gauge.
[0030] The beneficial effects achieved by the present utility model are as follows:
[0031] 1. The present utility model is provided with a slurry discharging assembly on the slurry conveying pipeline. When an instantaneous high pressure is generated in the slurry conveying pipeline due to the start of the machine pump or a sudden change in the conveying volume, the high-pressure mud can quickly enter the first cavity of the pressure relief chamber through the slurry discharging assembly, thereby effectively relieving the pressure peak in the pipeline and preventing the pipeline from bursting due to overpressure, ensuring the safe operation of the pipeline system.
[0032] 2. The pressure relief chamber of the present utility model is unidirectionally connected to the slurry conveying pipeline, that is, the mud in the pressure relief chamber can flow into the slurry conveying pipeline, but the mud in the slurry conveying pipeline cannot directly flow into the pressure relief chamber under normal operation. Instead, it can only flow into the pressure relief chamber through the slurry discharging assembly under specific conditions (such as overpressure), enabling the mud in the pressure relief chamber to flow back into the slurry conveying pipeline when the pressure decreases, achieving the effect of saving and utilization.

[0053] The technical solutions of this embodiment will be described in detail below with reference to specific drawings.
[0054] As Figure 1 and Figure 5 shown, this embodiment provides a pressure relief device for a slurry pipeline, including: a pressure relief chamber 1 and a slurry pipeline 2. The pressure relief chamber 1 is unidirectionally connected to the slurry pipeline 2, and the pressure relief chamber 1 is located above the slurry pipeline 2. The pressure relief chamber 1 includes a first cavity 11 for storing slurry. A slurry discharge assembly 3, one end of the slurry discharge assembly 3 is connected to the slurry pipeline 2, and the other end penetrates through the pressure relief chamber 1 into the first cavity 11 and is connected to the first cavity 11.
[0055] A slurry discharge assembly 3 is provided on the slurry pipeline 2. When an instantaneous high pressure is generated in the slurry pipeline 2 due to the start of a machine pump or a sudden change in the conveying volume, the high-pressure slurry can quickly enter the first cavity 11 of the pressure relief chamber 1 through the slurry discharge assembly 3, thereby effectively alleviating the pressure peak in the pipeline, preventing the pipeline from bursting due to overpressure, and ensuring the safe operation of the pipeline system.
[0056] The pressure relief chamber 1 is unidirectionally connected to the slurry pipeline 2, that is, the slurry in the pressure relief chamber 1 can flow to the slurry pipeline 2, but the slurry in the slurry pipeline 2 cannot directly flow to the pressure relief chamber 1 under normal operation. Instead, it only flows into the pressure relief chamber 1 through the slurry discharge assembly 3 under specific conditions (such as overpressure), so that the slurry in the pressure relief chamber 1 can flow back into the slurry pipeline 2 when the pressure decreases, achieving the effect of saving and utilization.
[0057] In this embodiment, the pressure relief chamber 1 is located above the slurry delivery pipeline 2. When the pressure in the slurry delivery pipeline 2 increases abnormally, the high-pressure slurry can quickly flow into the pressure relief chamber 1 located above through the slurry discharge components (such as the punching pipe 31 and the slurry discharge valve 32). Due to the effect of gravity, the slurry can naturally flow downward, making the pressure relief process smoother and more efficient, which helps to quickly reduce the pressure in the pipeline and prevent the pipeline from being damaged due to overpressure.
[0058] like Figure 1 As shown, the slurry discharge assembly 3 includes a punching pipe 31 and a slurry discharge valve 32. One end of the punching pipe 31 is connected to the slurry delivery pipeline 2, and the other end passes through the pressure relief chamber 1, and is connected to the first cavity 11 through the slurry discharge valve 32; the slurry discharge valve 32 is movably installed at the other end of the punching pipe 31, and the slurry discharge valve 32 is configured to be able to seal the other end of the punching pipe 31 under the action of gravity, and to be able to be lifted up to release the seal under the impact of the mud flowing in the punching pipe 31, so that the mud flowing in the punching pipe 31 can flow into the first cavity 11 through the slurry discharge valve 32.
[0059] The slurry discharge valve 32 can automatically seal the outlet of the punching pipe 31 under the action of its own gravity, and will automatically open under the impact of mud. This automatic adjustment mechanism makes the pressure relief process without manual intervention, improving the automation and operation stability of the system. When the pressure in the slurry pipeline 2 increases abnormally, the high-pressure mud can quickly impact the slurry discharge valve 32, causing it to lift and release the seal on the punching pipe 31, allowing the mud to quickly flow into the first cavity 11 of the pressure relief chamber 1, thereby quickly reducing the pressure in the pipeline and effectively preventing the pipeline from being damaged due to overpressure.
[0060] like Figures 2 - 4 As shown, the slurry discharge valve 32 includes a second cavity 321 and a slurry discharge channel, one end of the slurry discharge channel is connected to the side wall of the second cavity 321, and the other end is connected to the second cavity 321; the other end of the punching pipe 31 is installed in the second cavity 321, and under the gravity of the slurry discharge valve 32, the other end of the punching pipe 31 can abut against the top of the inner wall of the second cavity 321 and cover one end of the slurry discharge channel; under the impact of the mud flowing in the punching pipe 31, the slurry discharge valve 32 is lifted, and the other end of the punching pipe 31 can be away from the top of the inner wall of the second cavity 321 and expose one end of the slurry discharge channel, so that the mud can flow into the first cavity 11 through the slurry discharge channel.
[0061] In this embodiment, under the action of gravity, the other end of the punching pipe 31 of the slurry discharge valve 32 is tightly against the top of the inner wall of the second cavity 321, thereby closing one end of the slurry discharge channel. At this time, the slurry cannot flow into the first cavity 11 through the slurry discharge channel.
[0062] When the mud pressure in the slurry conveying pipeline 2 rises and impacts the stamping pipe 31, the stamping pipe 31 is jacked up under the pressure. As the stamping pipe 31 rises, the other end of it gradually moves away from the inner wall top of the second cavity 321, exposing one end of the slurry discharge channel. At this time, the high-pressure mud can smoothly flow into the first cavity 11, that is, the pressure relief chamber 1, through the slurry discharge channel, so as to achieve the purpose of pressure relief.
[0063] The design of the slurry discharge valve 32 enables high-pressure mud to be quickly and effectively introduced into the pressure relief chamber 1 when the pressure in the slurry conveying pipeline 2 abnormally rises, thus protecting the pipeline system from overpressure damage. The slurry discharge valve 32 is automatically triggered to open and close by the pressure of the mud, without manual intervention, improving the automation degree and response speed of the system. The slurry discharge channel is closed under normal conditions and only opens when the pipeline pressure rises, effectively preventing accidental leakage and backflow of the mud.
[0064] As Figures 2 - 4 shown, the slurry discharge channel includes a first pipeline 322, a second pipeline 323 and a third pipeline 324. One end of the first pipeline 322, one end of the second pipeline 323 and one end of the third pipeline 324 are respectively communicated with the side wall of the second cavity 321, and the other end of the first pipeline 322, the other end of the second pipeline 323 and the other end of the third pipeline 324 are communicated with the second cavity 321; and the first pipeline 322, the second pipeline 323 and the third pipeline 324 are distributed in the vertical direction.
[0065] In this embodiment, as Figure 6 and Figure 7 shown, the slurry discharge valve 32 is in the shape of a frustum of a cone. The number of the first pipelines 322, the second pipelines 323 and the third pipelines 324 is not less than two respectively. Each of the first pipelines 322, the second pipelines 323 and the third pipelines 324 is stratified in the vertical direction and evenly distributed on the frustum-shaped slurry discharge valve 32.
[0066] During the grouting work at the construction site, through power equipment such as the slurry conveying pipeline 2 and the pump, the cement in the slurry pool is transported to the production area. When the slurry in the slurry conveying pipeline 2 flows to the stamping pipe 31, part of the slurry will be conveyed to the stamping pipe 31. When the pump is started, due to the influence of voltage or manual configuration, the instantaneous pressure in the slurry conveying pipeline 2 will be too high. At this time, the slurry will rush to the top of the stamping pipe 31 to lift the slurry discharge valve 32 with a certain gravity. When the slurry pressure continuously lifts the slurry discharge valve 32 upwards, the first pipeline 322 is communicated with the second cavity 321, and the cement slurry will flow out from the first pipeline 322 to the first cavity 11, so that the pressure in the pipe is released. If the pipeline pressure is not released and the pressure continues to rise, the slurry discharge valve 32 continues to lift. When the second pipeline 323 is exposed and communicated with the second cavity 321, the slurry will flow out from the two-stage channel. Similarly, the specific pressure relief process of the third pipeline 324 can be obtained.
[0067] When the mud pressure in the slurry delivery pipeline 2 increases, the first pipeline 322 is first used for preliminary pressure relief. If the pressure continues to increase, the pressure is further released through the second pipeline 323 and the third pipeline 324. This graded pressure relief method can effectively avoid the impact and damage that may be caused by releasing excessive pressure at one time. Through multi-stage pressure relief, it can be ensured that under high pressure, the mud can flow into the pressure relief tank 1 smoothly and orderly, thereby reducing the safety risks such as pipeline rupture and leakage that may be caused by a sudden drop in pressure. The three-stage pressure relief design provides more pressure relief channels, so that under high pressure, the mud can flow into the pressure relief tank 1 faster through multiple channels, thereby improving the pressure relief efficiency.
[0068] like Figures 2 - 4 As shown, the slurry discharge valve 32 also includes a first limit member 325, which is arranged in the second cavity 321; the stamping tube 31 includes a second limit member 311, which is arranged at the other end of the stamping tube 31; the first limit member 325 is adapted to the second limit member 311.
[0069] The first limiting member 325 cooperates with the second limiting member 311 to limit the slurry discharge valve 32 from being separated from the other end of the stamping pipe 31 during the continuous lifting process.
[0070] In this embodiment, the first stopper 325 is a protrusion or step-like structure, which is installed at an appropriate position in the second cavity 321. The second stopper 311 is a protrusion or step-like structure at the other end of the stamping tube 31, and the size and shape of the protrusion or step are adapted to the first stopper 325. During the rising process of the stamping tube 31, the second stopper 311 contacts and interacts with the first stopper 325, thereby limiting its further rise.
[0071] Furthermore, the first stopper 325 can also be designed as an elastic buckle structure, which has one or more claws or protrusions that can expand outward. When the other end of the punching tube 31 is lifted upward under the impact of mud, the second stopper 311 will contact the claw or protrusion of the first stopper 325. As the punching tube 31 rises further, the claw or protrusion will expand outward and clamp the second stopper 311, thereby limiting its further rise.
[0072] like Figure 1 As shown, the pressure relief chamber 1 further includes a shell 12 and a discharge port 13 . The first cavity 11 is located in the shell 12 . The discharge port 13 is arranged at the bottom of the shell 12 and communicates with the first cavity 11 .
[0073] The housing 12 serves as the main structure of the pressure relief chamber 1. It not only provides a physical boundary for the first cavity 11 but also protects and isolates the mud inside it, preventing the mud from leaking out. Since the discharge port 13 is located at the bottom of the housing 12, due to the action of gravity, the mud can naturally settle at the bottom of the first cavity 11. This enables the mud to be discharged through the discharge port 13 when cleaning or discharging the mud is required, optimizing the mud flow path and reducing the residence time of the mud in the pressure relief chamber 1, thereby improving the overall efficiency.
[0074] As Figure 1 shown, the pressure relief chamber 1 further includes an inclined ladder 14, and the inclined ladder 14 is installed at the bottom of the first cavity 11 to enable the mud in the first cavity 11 to flow to the discharge port 13.
[0075] The inclined design of the inclined ladder 14 enables the mud in the first cavity 11 to flow naturally along the surface of the inclined ladder to the discharge port 13, optimizing the mud flow path, reducing the residence time of the mud in the cavity, and improving the mud discharge efficiency. Through the guidance of the inclined ladder, solid particles and impurities in the mud are not easily deposited at the bottom of the first cavity, thus reducing the difficulty of cleaning and maintenance.
[0076] As Figure 1 and Figure 5 shown, it further includes a return pipe 4. One end of the return pipe 4 is connected to the discharge port 13, and the other end is connected to the slurry conveying pipe 2.
[0077] Through the return pipe 4, the mud discharged from the discharge port 13 can be re-introduced into the slurry conveying pipe 2 to achieve the recycling of the mud. This helps to reduce the waste of mud and lower the production cost.
[0078] As Figure 1 shown, it further includes a check valve 5, and the check valve 5 is installed on the return pipe 4 to enable the pressure relief chamber 1 to be unidirectionally connected to the slurry conveying pipe 2.
[0079] The main function of the check valve 5 is to ensure that the mud can only flow unidirectionally from the pressure relief chamber 1 to the slurry conveying pipe 2 and cannot flow reversely. This effectively prevents the mud from flowing back from the slurry conveying pipe 2 to the pressure relief chamber 1 during system pressure fluctuations or operating errors, ensuring the stable operation of the system. By restricting the flow direction of the mud, the check valve 5 helps to prevent the system pressure from getting out of control due to mud backflow and reduces the risk of accidents caused by excessive pressure.
[0080] In this embodiment, the pressure relief chamber 1 and the slurry discharging assembly 3 are connected to the slurry conveying pipe 2 through an interface assembly. After the device is used up, it can be quickly removed and taken out through the joint position. For the residual mud and slag inside, tap water can be poured into one end of the stamping pipe 31, and the clear water carrying the mud and slag will flow out from the check valve 5 to achieve the effect of cleaning the internal space.
[0081] As Figure 1 shown, it further includes a pressure gauge 6, and the pressure gauge 6 is installed on the pressure relief chamber 1.
[0082] The staff can judge whether the device is in a normal working state by checking the reading of the pressure gauge 6.
