Description

Technical Field

[0001] This utility model relates to the field of HVAC piping technology, and in particular to a sealing pipe joint. Background Technology

[0002] Piping systems play a vital role in industries such as manufacturing, construction, and energy. Especially in exhaust systems, the structural design and connection methods of pipelines directly affect the system's operating efficiency and stability. As key components connecting different pipe sections, the structural strength and airflow efficiency of pipe joints are particularly important. However, under complex operating conditions, especially in environments with high pressure, high temperature, or corrosive media, existing pipe joints are prone to structural deformation and uneven media flow, leading to decreased system efficiency or failure. Therefore, a sealing pipe joint is needed to improve the operating efficiency and stability of pipelines, ensuring that the pipeline structure does not deform and that the media flow is uniform. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model provides a sealed pipe joint, which solves the technical problem that pipe structures are prone to structural deformation and uneven medium flow in high-pressure, high-temperature or corrosive media environments, resulting in low operating efficiency of the pipe system.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0005] A sealing pipe joint includes: a base on which a pipe body is mounted; an annular cover fitted onto the pipe body, with a cavity between the annular cover and the pipe body; a set of ejectors disposed on the inner wall of the pipe body, the ejectors being evenly spaced along the circumference of the pipe body, and each ejector communicating with the cavity; each ejector including: a horn-shaped nozzle oriented in the same direction as the flow direction of the medium within the pipe body; and a connector pipe mounted on the outer wall of the annular cover, communicating with the cavity.

[0006] Based on the above structure, the principle of the aforementioned sealing pipe joint is as follows: when the medium flows inside the pipe, a set of ejectors is set on the inner side wall of the pipe and evenly spaced circumferentially.

[0007] Furthermore, the horn-shaped nozzles of a set of ejectors are oriented in the same direction as the medium flow. High-pressure clean air or medium is injected into the cavity through the connector pipe. Since the set of ejectors is connected to the cavity, the clean air or medium is ejected at high speed from the horn-shaped nozzles. The flow velocity of the medium in the pipeline and behind the horn-shaped nozzles increases, and the flow velocity of the medium behind the horn-shaped nozzles will be greater than that in other parts of the pipeline. As the flow velocity of the medium increases, the pressure of the medium will decrease, thus forming a low-pressure zone around the horn-shaped nozzles. This low-pressure zone will exert a suction force on the surrounding medium, thereby increasing the flow velocity of the medium in the entire pipeline and ensuring the high efficiency of pipeline transportation. The formation of a low-pressure zone, the suction force on the surrounding medium, further pulls the medium flow, enhances the fluidity of the medium, reduces the risk of medium stagnation or accumulation in the pipeline, and ensures the continuity of pipeline operation. The set of ejectors is evenly spaced along the circumference of the pipe body to ensure that the medium in all parts of the pipeline cross-section can be effectively accelerated, avoiding the problem of excessively high or low local pressure in the pipeline caused by uneven flow velocity, making the pressure distribution in the pipeline more balanced and extending the service life of the pipeline.

[0008] Furthermore, in one type of sealed pipe node of this application, the pipe body includes a pair of flow channels, each pair including an inlet and an outlet, wherein the inner diameter of the outlet is smaller than the inner diameter of the inlet. As a preferred embodiment of this application, in this type of sealed pipe node, when the medium enters the pipe body from the inlet, the narrowing of the outlet reduces the amount of medium passing through the outlet per unit time, causing the medium to flow faster as it passes through this point. This results in the medium having higher kinetic energy upon exiting, further accelerating the medium flow speed and improving transportation efficiency.

[0009] Furthermore, in one type of sealing pipe joint of this application, the base includes: a base plate, on which a first support plate and a set of second support plates are provided, the set of second support plates being spaced apart along the extending direction of the first support plate, and the first support plate and the set of second support plates being arranged in a cross shape. As a preferred embodiment of this application, in this type of sealing pipe joint, the base serves as a basic load-bearing component, bearing the weight from the upper pipe body, annular casing, and medium, etc. The first support plate and the set of second support plates are arranged in a cross shape, forming a stable support frame to ensure the overall stability of the pipe joint.

[0010] Furthermore, in one type of sealed pipe node of this application, a reinforcing plate is provided between each pair of adjacent second support plates, and the reinforcing plate is connected to the first support plate and the adjacent pair of second support plates respectively. As a preferred embodiment of this application, the reinforcing plate, as an additional support structure, enhances the overall cushioning capacity of the base against pressure changes in the sealed pipe node, ensuring the stability of the pipe node under complex working conditions.

[0011] Furthermore, in one sealing pipe joint of this application, a set of first reinforcing plates and a set of second reinforcing plates are provided on the outer side of the annular cover. The first set of first reinforcing plates is spaced apart along the axial direction of the pipe body, and the second set of first reinforcing plates extends radially along the pipe body. The first reinforcing plates and the second set of second reinforcing plates intersect in a cross shape. As a preferred embodiment of this application, the cross-intersection of the first and second reinforcing plates in this sealing pipe joint forms a stable grid structure, enhancing the overall deformation resistance of the annular cover and effectively avoiding problems such as cracks and deformation caused by uneven stress.

[0012] Furthermore, in a sealing pipe node of this application, the ejector further includes an arc-shaped tube disposed on the inner wall of the pipe body. The arc-shaped tube is detachably connected to the horn-shaped nozzle. Corresponding to the flow direction of the medium in the pipe body, a flow divider is provided on the outer side of the arc-shaped tube. The flow divider is used to reduce the flow resistance of the medium in the pipe body when it flows through the arc-shaped tube. As a preferred embodiment of this application, in a sealing pipe node of this application, when the medium in the pipe body is continuously flowing, the medium flows through the flow divider of the arc-shaped tube. The flow divider can reasonably guide and distribute the medium flow, diverting the fluid that originally concentrated on impacting the arc-shaped tube, making the laminar flow state of the fluid more stable, effectively reducing the generation of turbulence, and thus reducing the flow resistance of the medium in the pipe body when it flows through the arc-shaped tube, thereby improving the conveying efficiency. The detachable design of the arc-shaped tube and the horn-shaped nozzle makes it convenient for maintenance personnel to quickly replace the new arc-shaped tube without large-scale disassembly of the entire ejector when the horn-shaped nozzle is damaged, shortening maintenance time, reducing maintenance costs, and reducing the impact of downtime on production operations.

[0013] Furthermore, a sealing pipe joint in this application further includes a reinforcing ring plate, which is sleeved on the connector pipe and mounted on the annular cover. As a preferred embodiment of this application, the reinforcing ring plate in the sealing pipe joint enhances the stability of the connection between the connector pipe and the annular cover, preventing loosening or cracking at the connection point and extending the service life of the connector pipe and the entire pipe joint.

[0014] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0015] This utility model provides a sealed pipeline node. By installing ejectors with uniformly spaced circumferentially spaced, funnel-shaped nozzles facing the same direction as the medium flow on the inner wall of the pipe, and injecting high-pressure clean air or medium into the cavity, it increases the medium flow rate, ensures efficient transportation, and balances the pressure distribution within the pipeline. The design of the outlet inner diameter being smaller than the inlet inner diameter accelerates the flow velocity of the medium upon exiting. A base with a stable support frame formed by intersecting first and second support plates, along with additional reinforcing plates, enhances the stability of the base. The grid structure formed by the intersecting first and second reinforcing plates improves the deformation resistance of the annular cover. An arc-shaped pipe with a flow divider is detachably connected to the funnel-shaped nozzle, reducing medium flow resistance and facilitating maintenance. A reinforcing ring plate is added to strengthen the stability of the connection between the joint pipe and the annular cover. Attached Figure Description

Detailed Implementation

[0021] like Figure 1 , 2As shown in Figure 3, a sealed pipe joint includes: a base 1, on which a pipe body 2 is mounted; an annular cover 3, which is fitted onto the pipe body 2, and a cavity 30 is provided between the annular cover 3 and the pipe body 2; a set of ejectors 4, which are disposed on the inner side wall of the pipe body 2, and are evenly spaced along the circumference of the pipe body 2, and are all connected to the cavity 30; each ejector 4 includes: a horn-shaped nozzle 40, the orientation of which is consistent with the flow direction of the medium inside the pipe body 2; and a connector pipe 5, which is installed on the outer side wall of the annular cover 3 and is connected to the cavity 30.

[0022] Based on the above structure, the principle of the sealing pipe node is as follows: When the medium flows inside the pipe body 2, a set of ejectors 4 are set on the inner wall of the pipe body 2 and evenly spaced circumferentially. The horn-shaped nozzles 40 of the ejectors 4 face the same direction as the medium flow. High-pressure clean air or medium is injected into the cavity 30 through the connector pipe 5. Since the set of ejectors 4 is connected to the cavity 30, the clean air or medium will be ejected at high speed from the horn-shaped nozzles 40. The flow velocity of the medium behind the horn-shaped nozzles 40 in the pipe will increase, and the flow velocity of the medium behind the horn-shaped nozzles 40 will be greater than that in other parts of the pipe. As the flow velocity of the medium increases, the medium... The pressure will decrease, thus creating a low-pressure zone around the horn-shaped nozzle 40. This low-pressure zone will exert suction on the surrounding medium, thereby increasing the flow velocity of the medium throughout the pipeline and ensuring the high efficiency of pipeline transportation. The formation of the low-pressure zone, by exerting suction on the surrounding medium, further pulls the medium flow, enhances the fluidity of the medium, reduces the risk of medium stagnation or accumulation in the pipeline, and ensures the continuity of pipeline operation. A set of ejectors 4 are evenly spaced along the circumference of the pipe body 2 to ensure that the medium in each part of the pipeline cross-section can be effectively accelerated, avoiding the problem of excessively high or low local pressure in the pipeline caused by uneven flow velocity, making the pressure distribution in the pipeline more balanced and extending the service life of the pipeline.

[0023] In this embodiment, the pipe body 2 includes a pair of flow channels, each comprising an inlet 21 and an outlet 22, wherein the inner diameter of the outlet 22 is smaller than the inner diameter of the inlet 21. When the medium enters the pipe body 2 from the inlet 21, the narrowing of the outlet 22 reduces the amount of medium passing through it per unit time, causing the medium to flow faster as it passes through this point. This results in the medium having higher kinetic energy when it leaves, further accelerating the flow speed and improving transportation efficiency.

[0024] like Figure 4As shown, in this embodiment, the base 1 includes a base plate 11, on which a first support plate 12 and a set of second support plates 13 are provided. The set of second support plates 13 are spaced apart along the extending direction of the first support plate 12, and the first support plate 12 and the set of second support plates 13 are arranged in a cross shape. The base 1, as a basic load-bearing component, bears the weight from the upper pipe body 2, the annular cover 3, and the medium, etc. The cross arrangement of the first support plate 12 and the set of second support plates 13 forms a stable support frame to ensure the overall stability of the pipeline node. The orientation of the first support plate 12 is perpendicular to the axial direction of the pipe body 2.

[0025] In this embodiment, a reinforcing plate 14 is provided between each pair of adjacent second support plates 13. The reinforcing plate 14 is connected to the first support plate 12 and the adjacent pair of second support plates 13, respectively. As an additional support structure, the reinforcing plate 14 enhances the overall buffering capacity of the base 1 against pressure changes and ensures the stability of the pipeline node under complex working conditions.

[0026] In this embodiment, the outer side of the annular cover 3 is provided with a set of first reinforcing plates 6 and a set of second reinforcing plates 7. The first reinforcing plates 6 are spaced apart axially along the tube body 2, and the second reinforcing plates 7 extend radially along the tube body 2. The first reinforcing plates 6 and the second reinforcing plates 7 are spaced apart circumferentially along the tube body 2, and intersect at an angle. This intersection of the first reinforcing plates 6 and the second reinforcing plates 7 forms a stable grid structure, enhancing the overall deformation resistance of the annular cover 3 and effectively preventing cracks and deformations caused by uneven stress. There are two first reinforcing plates 6 and eleven second reinforcing plates 7.

[0027] In this embodiment, the ejector 4 further includes an arc-shaped tube 41, which is disposed on the inner wall of the tube body 2. The arc-shaped tube 41 is detachably connected to the horn-shaped nozzle 40. Corresponding to the flow direction of the medium in the tube body 2, a flow divider 8 is provided on the outer side of the arc-shaped tube 41. The flow divider 8 is used to reduce the flow resistance of the medium in the tube body 2 when it flows through the arc-shaped tube 41. When the medium flows continuously inside the pipe body 2, it passes through the diversion section 8 of the arc-shaped pipe 41. The diversion section 8 can reasonably guide and distribute the medium flow, diverting the fluid that originally concentrated on impacting the arc-shaped pipe 41, making the laminar flow state more stable, effectively reducing the generation of turbulence, and thus reducing the flow resistance of the medium inside the pipe body 2 when flowing through the arc-shaped pipe 41, thereby improving the conveying efficiency. The arc-shaped pipe 41 and the horn-shaped nozzle 40 are designed to be detachable, so that when the horn-shaped nozzle 40 is damaged, maintenance personnel can quickly replace the new arc-shaped pipe 41 without large-scale disassembly of the entire ejector 4, shortening maintenance time, reducing maintenance costs, and reducing the impact of downtime on production operations. Each arc-shaped pipe 41 has two diversion sections 8 on its outer side.

[0028] In this embodiment, a reinforcing ring plate 9 is further included. The reinforcing ring plate 9 is sleeved on the connector pipe 5 and installed on the annular cover 3. The reinforcing ring plate 9 is used to enhance the stability of the connection position between the connector pipe 5 and the annular cover 3, prevent loosening or cracking at the connection point between the connector pipe 5 and the annular cover 3, and extend the service life of the connector pipe 5 and the entire pipe joint.
