Description

Technical Field

[0001] The present application relates to the technical field of pipeline connection, and in particular to a three-way pipe fitting. Background Art

[0002] At present, in the fluid transportation system, pipeline connection technology has been widely used and developed. Traditional pipeline connection methods mainly include welding, threaded connection, flange connection, etc. Although these traditional connection methods meet the actual needs to a certain extent, they still have many shortcomings in terms of installation convenience, sealing performance, corrosion resistance and maintenance convenience.

[0003] In the related art, among the existing technical means, a common method is to control the medium flow by installing sensors and regulating valves inside the three-way pipe fitting. These sensors can monitor parameters such as pressure, temperature and flow in the pipeline in real time, and feed the data back to the control system, and the regulating valve automatically adjusts the degree of opening and closing according to these data to achieve the purpose of balancing the pressure and flow at the two outlet ends. In addition, there is a simpler method of setting a fixed partition plate inside the three-way pipe fitting, and physically changing the flow area ratio of the two outlet ends to achieve the basic flow distribution function. However, this method has poor flexibility and cannot be dynamically adjusted according to actual needs.

[0004] Regarding the above-mentioned related technologies, installing sensors and regulating valves will significantly increase the cost of three-way pipe fittings, which is unacceptable for some low-cost application scenarios. Secondly, the complex structural design makes the manufacture and maintenance of three-way pipe fittings more difficult, increasing the difficulty of production and use. Therefore, how to achieve effective control of the medium flow in the three-way pipe fittings without significantly increasing the cost has become a technical problem that needs to be solved urgently. Summary of the invention

[0005] In order to achieve effective control of the medium flow in a three-way pipe fitting, the present application provides a three-way pipe fitting.

[0006] The present application provides a three-way pipe fitting, which adopts the following technical solution: A three-way pipe fitting comprises a pipe body and a first flow dividing component; The pipeline body comprises a first pipeline and a second pipeline perpendicular to each other, one end of the first pipeline is a water inlet end, and the other end is connected to the second pipeline, one end of the second pipeline is a first water outlet end, and the other end is a second water outlet end, and a diversion cavity is formed at the connection between the first pipeline and the second pipeline; The first flow dividing assembly is installed in the flow dividing chamber, and the flow dividing assembly includes a connecting rod and a flow dividing plate; The connecting rod is parallel to the pipe length direction of the first pipeline, the connecting rod is connected to the pipeline body, two diverter plates are connected to the connecting rod, the two diverter plates are inclined, the diverter plates are symmetrically arranged along the connecting rod, a water gap is provided between the diverter plates and the side wall of the first pipeline, the diverter plates are rotatably connected to the connecting rod, and the rotation axis of the diverter plates along the connecting rod is perpendicular to both the pipe length direction of the first pipeline and the pipe length direction of the second pipeline.

[0007] By adopting the above technical solution and setting a first diverter assembly, water flows into the first pipe through the water inlet end and contacts the two diverter plates. Under the guidance of the diverter plates, the water flows into the second pipe and is discharged from the first water outlet end and the second water outlet end. By setting the diverter plates, the uniformity of water discharged from the first water outlet end and the second water outlet end can be improved, and the uniformity of water flow at both ends of the second pipe can be improved. When the water flow passing through the first pipe is large, a large pressure is applied to the diverter plate to rotate the diverter plate toward the side close to the connecting rod, thereby increasing the width of the water gap to facilitate the passage of water.

[0008] Optionally, the first diverter assembly also includes a first elastic member, one end of the first elastic member is directly or indirectly connected to the diverter plate, and the other end is directly or indirectly connected to the side wall of the connecting rod, and the first elastic member has a force to drive the diverter plate to move away from the connecting rod under recoverable deformation.

[0009] By adopting the above technical solution, a first elastic member is set, and the first elastic member is connected between the connecting rod and the diverter plate. Under the action of the first elastic member, when no water flows through the first pipe, the diverter plate is in the initial position, and the diverter plate is inclined. When the water flow rate is large, the water flow exerts pressure on the diverter plate to rotate the diverter plate toward the side close to the connecting rod. When the water flow rate decreases, the diverter plate gradually rotates from the side close to the connecting rod to the initial position.

[0010] Optionally, a second diverter component is also included, and the second diverter component also includes a diverter pipe and a first sliding seat. The diverter pipe is parallel to the second pipeline, and a plurality of first diverter holes and second diverter holes are arranged on the diverter pipe along its own circumferential direction. The first sliding seat is located in the diverter pipe, and the first sliding seat slides along the tube length direction of the diverter pipe. The first diverter hole and the second diverter hole are respectively arranged at both ends of the first sliding seat, and the first diverter hole is connected to the diverter cavity, and the second diverter hole is connected to the diverter cavity.

[0011] By adopting the above technical solution, when the water flows into the second pipe, there may be a difference in the water pressure at the first water outlet end and the second water outlet end in the second pipe. For this reason, by setting a second diversion component, when the water pressure at the first water outlet end and the second water outlet end in the second pipe is different, for example, if the water pressure at the first water outlet end is larger, the first sliding seat will be pushed to slide in the diversion pipe toward the second water outlet end, so that the first sliding seat slides toward the second diversion hole. The first sliding seat will further block the second diversion hole, thereby reducing the water flow space of the second diversion hole, changing the distribution amount of water entering from the second diversion hole, and thus balancing the water flow pressure at both ends of the second pipe.

[0012] Optionally, a limiting ring is further included, which is located in the second pipeline. A limiting ring is provided at each end of the diversion pipe. The limiting ring is clamped on the second pipeline. The limiting ring is in contact with the diversion pipe so as to prevent the diversion pipe from sliding out of the second pipeline.

[0013] By adopting the above technical solution, in order to reduce the sliding of the shunt tube in the second pipe, limiting rings are provided at both ends of the shunt tube to block the sliding of the shunt tube in the second pipe, thereby improving the stability of the shunt tube in the second pipe.

[0014] Optionally, a first slide groove is opened on one side of the diverter pipe along the length direction of the diverter pipe, and one end of the connecting rod away from the diverter plate passes through the first slide groove and is connected to the first sliding seat.

[0015] By adopting the above technical solution, in order to further adjust the water flow pressure at both ends of the second pipe, a connecting pipe is provided to be connected to the first sliding seat. When the first sliding seat slides along the length direction of the second pipe, the connecting rod drives the diverter plate to slide in the first pipe, thereby changing the width of the water gap between the diverter plate and the inner wall of the first pipe, and further adjusting the water flow through the first pipe. If the water pressure at the first water outlet is relatively large, the first sliding seat will be pushed to slide in the diverter pipe toward the second water outlet, driving the connecting rod to slide, and the area of ​​the second diverter hole will be reduced. The water gap between the diverter plate close to the second water outlet and the inner wall of the first pipe will also be reduced, thereby reducing the water flow, and the water pressure at the second water outlet end of the water flowing through the second diverter hole into the second pipe will increase, and the water pressure at the second water outlet end further adjusted to a balanced state.

[0016] Optionally, the connecting rod is connected to each of the diverter plates via a telescopic rod, the telescopic rod is located on a side of the diverter plate close to the diverter tube, the movable section of the telescopic rod is rotatably connected to the diverter plate, the fixed section of the telescopic rod is rotatably connected to the connecting rod, and the movable section and the fixed section of the telescopic rod are slidably connected at one end thereof.

[0017] By adopting the above-mentioned technical scheme, in order to enable the diverter plate to always divert the water flow entering the first water pipe, if one side of the diverter plate contacts the side wall of the connecting rod, the diverter plate cannot guide and divert the water flow. To this end, a telescopic rod is arranged between the diverter plate and the connecting rod so that the diverter plate cannot contact the connecting rod during rotation, thereby ensuring that the diverter plate can still divert the water flow no matter how large the water flow is.

[0018] Optionally, a second sliding seat is sleeved on the connecting rod, and the second sliding seat slides along the length direction of the connecting rod. One end of the telescopic rod away from the diverter plate is rotatably connected to the second sliding seat, and the other end of the telescopic rod away from the diverter plate is rotatably connected to the second sliding seat.

[0019] By adopting the above technical solution, when water flows into the first pipe, in order to make the water flow through the two diverter plates to the second pipe as even as possible, a second sliding seat is set. When one of the diverter plates rotates under the action of water pressure, the second sliding seat is driven to slide along the length direction of the connecting rod, so that the second sliding seat drives the other diverter plate to rotate, so as to ensure that the rotation angles of the two diverter plates are the same, so that the water flow through the two diverter plates is the same.

[0020] Optionally, the connecting rod is detachably connected to the first sliding seat.

[0021] By adopting the above technical solution, a connecting rod is detachably connected to the first sliding seat, so that personnel can install the connecting rod and the diverter plate easily.

[0022] Optionally, it also includes a connecting component, which includes two fixed rods, a second mounting seat and a mounting block, two second mounting seats are fixedly connected to the first sliding seat, the connecting rod is arranged between the two second mounting seats, the connecting rod is provided with a second slide groove along the length direction of its own rod, and each of the two side walls of the connecting rod is provided with a third slide groove, the third slide groove is connected to the second slide groove, one end of the fixed rod is located above the connecting rod, and the other end is located in the third slide groove, the fixed rod slides in the second slide groove parallel to the length direction of the second pipeline, the mounting block is fixedly connected to the side wall of the fixed rod, the third slide groove is used for the mounting block to slide out of the second slide groove, and a receiving groove for accommodating the mounting block is provided on one side of the second mounting seat.

[0023] By adopting the above technical solution, in order to connect the first sliding seat with the connecting rod, a connecting assembly is set, the two connecting rods are slid toward the side close to each other, driving the mounting block to move toward the second sliding groove, and the connecting rod is placed between the two second mounting seats, and then the two connecting rods are slid toward the side away from each other, so as to slide the mounting block from the third sliding groove to the accommodating groove, thereby realizing the connection between the connecting rod and the first sliding seat.

[0024] Optionally, the connecting assembly also includes a second elastic member, which is located in the second slide groove, the extension and contraction direction of the second elastic member is parallel to the second pipe, one end of the second elastic member is fixedly connected to the wall of the second slide groove, and the other end is fixedly connected to the fixed rod, and the second elastic member has a force to drive the second mounting seat to move toward the outside of the third slide groove under recoverable deformation.

[0025] By adopting the above technical solution, in order to connect the fixed rod and the connecting rod, a second elastic member is set. When a person pulls the two fixed rods toward each other, the second elastic member is stretched. When the person lets go, the mounting block further enters the accommodating groove under the action of the second elastic member, thereby realizing the connection and fixation between the connecting rod and the first sliding seat.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. The present application sets a first flow dividing assembly, and water flows into the first pipe through the water inlet end and contacts the two flow dividing plates. Under the guidance of the flow dividing plates, the water flows into the second pipe and then is discharged from the first water outlet end and the second water outlet end. By setting the flow dividing plates, the uniformity of water flow discharged from the first water outlet end and the second water outlet end can be improved.

When the water flow rate decreases, the diverter plate 22 gradually rotates from the side close to the connecting rod 21 to the initial position.

[0033] Reference Figure 2 and Figure 4 , when the water flows into the second pipe 12, there may be a difference in water pressure between the first water outlet end 121 and the second water outlet end 122 in the second pipe 12. For this reason, the three-way pipe fitting further includes a second diverter assembly 3, and the second diverter assembly 3 further includes a diverter pipe 31 and a first sliding seat 32. The diverter pipe 31 is parallel to the second pipe 12.

[0041] The implementation principle of a three-way pipe fitting in the embodiment of the present application is as follows: the first flow diversion component 2 and the second flow diversion component 3 are installed in the pipe body 1, and the water flows into the first pipe 11 through the water inlet end 111 and contacts the two diversion plates 22. Under the guidance of the diversion plates 22, the water flows into the second pipe 12 and is discharged from the first water outlet end 121 and the second water outlet end 122.

The water gap 23 between the diverter plate 22 near the second water outlet end 122 and the inner wall of the first pipe 11 will also be reduced, thereby reducing the water flow rate. The water pressure at the second water outlet end 122 of the second pipe 12 that flows through the second diverter hole 312 will increase, and the water pressure at both ends of the second pipe 12 will be further adjusted to a balanced state.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
