Technical Field

[0001] The utility model relates to the technical field of swirl tees, in particular to a same-layer swirl tee. Background Art

[0002] Special single-riser pipes are used for domestic drainage in building bathrooms. They offer the advantages of high drainage flow and a small footprint, and have been widely used in the market in recent years. Special single-riser pipe systems primarily consist of reinforced spiral pipes as the drainage riser. Where the horizontal branch pipes merge into the riser, a specially constructed swirl tee is used to eliminate interference between the horizontal and vertical pipe flows. When used for same-floor drainage, the swirl tee is tall and needs to extend through the floor slab into the lower level. The fire arrester ring needs to fit snugly over the swirl tee. Since the swirl tee has a tapered contraction at the lower end of the expansion section, a cylindrical sleeve is required to complement the fire arrester ring.

[0003] CN205606060U in the Chinese patent document discloses a single-riser drainage pipe fitting installed on the same floor. The application includes an upper cover, a four-way main body, a water collector and a spiral bucket. The upper and lower ends of the upper cover are both socket structures, the upper end of which is used to connect the riser, and the lower end of which is used to connect the four-way main body; the upper and lower ends of the four-way main body are both socket structures, the upper end of which is used to connect the upper cover, and the lower end of which is used to connect the water collector. The sides of the four-way main body are respectively provided with a left-handed horizontal branch pipe interface, other drainage pipe interfaces and a water accumulation hole. The left-handed horizontal branch pipe interface is at a vertical angle to the other drainage pipe interfaces. The left-handed horizontal branch pipe interface is used to connect the same-floor drainage pipe at the left end of the riser, and the other drainage pipe interfaces are used to connect other drainage pipes on the same floor; the upper and lower ends of the water collector are both socket structures, the upper end of which is used to connect the four-way main body, and the lower end of which is used to connect the riser. The spiral bucket is a funnel structure, the spiral bucket is embedded in the water collector, and the inner wall of the spiral bucket is also provided with blades for maintaining stability and enhancing the rotation state of the water flow.

[0004] The existing technology has the following problems:

[0005] 1. This product is assembled from four parts. As a plastic product, it requires four sets of molds for molding, which has high mold costs.

[0006] 2. The four-part structure is complex, and the wall thickness of the joints, water collectors and spiral buckets overlap a lot, resulting in high material costs. Utility Model Content

[0007] In order to overcome the above-mentioned deficiencies in the prior art, the present invention provides a same-layer swirl tee, which reduces the material cost of the fitting itself on the one hand, and reduces the construction cost through structural optimization on the other hand.

[0008] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0009] A same-layer swirl tee comprises a tee body and a cone body, one of the tee body and the cone body is provided with a plug-in portion, and the other is provided with a socket portion, the plug-in portion and the socket portion cooperate to realize the connection between the tee body and the cone body, and the socket portion is provided with a drainage interface; the tee body comprises an inner hollow body, a first riser interface and a horizontal branch pipe interface that are coplanarly arranged and interconnected, the cone body comprises a water through hole and a second riser interface, the wall surface of the water through hole is provided with a swirl guide portion, and after the inner hollow body is connected to the cone body, the interior of the inner hollow body is connected to the second riser interface through the water through hole.

[0010] The same-layer swirl tee disclosed in the present application includes a tee body and a cone that are plugged together. The swirl guide portion guides the water flow in the water hole. The tee body and the cone are easy to connect. Since the inner hollow main body, the first vertical pipe interface and the horizontal branch pipe interface in the tee body are coplanar, the tee body can be integrally formed by injection molding or casting. The mold structure is simple and easy to form. The production cost and assembly cost of the tee are greatly reduced compared with the existing technology.

[0011] Preferably, the cone comprises an integral large and small cone sections. The large cone section connects to the tee, and a second riser interface is provided at the outer end of the small cone section. The cone angle of the small cone section is smaller than that of the large cone section. The cone is a monolithic structure capable of being formed in one step. Two table-like through-holes are formed within the large and small cone sections of the cone, which serve to converge flow. Together with the swirl guide, they can reliably form a swirl flow, reducing interference between the horizontal and vertical pipe flows. Due to its smaller cone angle, the small cone section can serve as a mounting component to facilitate installation of the fire arrester ring.

[0012] Preferably, the tee is provided with a plug-in portion, the cone is provided with a socket portion, and the drainage interface is integrally provided with the cone. In one embodiment of the cone having a socket portion, one end of the tee can be plugged into the socket portion, facilitating assembly.

[0013] Preferably, a plurality of spaced support portions are provided on the outside of the small conical section, and the support portions are arranged along the axis of the small conical section. The support portions can support the installation of the fire arrester ring. The small conical section itself has a small cone angle, which facilitates the installation of the support portions.

[0014] Preferably, the support portion is in the shape of a ring, and all the support portions have the same outer diameter, which is between 124 and 126 mm. The support portion of this size can be installed with a 125 specification fire arrester ring, and the support portion has a reliable supporting effect.

[0015] Preferably, a plurality of water-blocking rings are provided on the outer periphery of the large tapered section, so that the tee can prevent water leakage after being bonded to the floor slab cement.

[0016] As a preferred embodiment, the splice portion and the socket portion are bonded after being spliced ​​together to avoid easy separation of the splice portion and the socket portion and ensure the overall performance of the tee and cone after being connected.

[0017] Preferably, the inner hollow body has a cylindrical outer contour, with an outer diameter between 140 and 165 mm. If the outer diameter of the inner hollow body is too small, water entering the horizontal branch pipe will interfere with the drainage of the vertical pipe, resulting in poor ventilation and reduced drainage flow. If the outer diameter of the inner hollow body is too large, the cone portion will be too long to maintain a certain taper, which will not only increase the material cost of the product but also affect the installation of the fire arrester.

[0018] Preferably, the drainage interface is arranged radially along the cone, with the junction between the large and small cone sections less than 100 mm from the bottom edge of the drainage interface. A typical floor slab is 100 mm thick, and this preferred size restriction ensures that the large cone section is completely buried within the floor slab during tee installation.

[0019] Preferably, the three-way body is integrally formed of plastic material, which has high molding efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] As one of the embodiments of the present invention, a same-layer swirl tee is disclosed, such as Figures 1 to 4As shown, it includes a tee 1 and a cone 5, one of the tee 1 and the cone 5 is provided with a plug-in portion 101, and the other is provided with a socket portion 6. The plug-in portion 101 and the socket portion 6 are socket-fitted to realize the connection between the tee 1 and the cone 5, and the socket portion 6 is provided with a drainage interface 7; the tee 1 includes an inner hollow body 2, a first riser interface 3 and a horizontal branch pipe interface 4 that are coplanar and interconnected, the cone 5 includes a water hole 8 and a second riser interface 9, and the wall surface of the water hole 8 is provided with a swirl guide portion 10. After the inner hollow body 2 is connected to the cone 5, the interior of the inner hollow body 2 is connected to the second riser interface 9 through the water hole 8.

[0027] The same-layer swirl tee disclosed in this application includes a tee body 1 and a cone body 5 that are plug-fitted together. The swirl guide portion 10 serves to guide the water flow in the water hole 8. In this embodiment, the swirl guide portion 10 is a spiral tooth rib distributed in a circumferential array on the wall of the water hole 8 of the cone body 5. The tee body 1 and the cone body 5 are easy to connect. The inner hollow body 2, the first vertical pipe interface 3 and the horizontal branch pipe interface 4 of the tee body 1 are arranged in the same plane. The tee body 1 is formed in one piece by injection molding using a plastic material. The mold structure is simple and demoulding is convenient. The tee body 1 is easy to form. The production cost and assembly cost of the same-layer swirl tee are greatly reduced compared to the existing technology. It can be understood by those skilled in the art that the tee body 1 can also be formed in one piece by casting using metal parts.

[0028] As a setting method of this embodiment, Figure 2 and Figure 3 As shown, the tee 1 is provided with a plug-in portion 101, the cone 5 is provided with a socket portion 6, and the drainage interface 7 is integrally provided with the cone 5. In this embodiment, the lower end of the tee 1 directly serves as the plug-in portion 101, without any other plug-in structure. One end of the tee 1 can be plugged into the socket portion 6, facilitating assembly. The integral provision of the drainage interface 7 and cone 5 improves the efficiency of cone 5 molding.

[0029] As a simple replacement for the above solution, the tee 1 may be provided with a socket portion, and the cone 5 may be provided with a plug portion.

[0030] Furthermore, in order to prevent the plug-in portion 101 and the socket portion 6 from being easily separated and to ensure the overall performance of the tee 1 and the cone 5 after being connected, the plug-in portion 101 and the socket portion 6 are bonded after being plugged in. The bonding here is only a fixed connection between the tee 1 and the cone 5, and is not limited to a bonding seal between the tee 1 and the cone 5.

[0031] As one of the embodiments of the present invention, a same-layer swirl tee is disclosed, such as Figures 1 to 4As shown, the cone 5 is an integral conical cavity structure, with the large cone section 11 and the small cone section 12 forming an integral structure. The large cone section 11 is connected to the tee 1, and the outer end of the small cone section 12 is provided with a second riser interface 9. The cone angle of the small cone section 12 is smaller than that of the large cone section 11. In this embodiment, the cone angle m of the small cone section 12 is 10.29 degrees, and the cone angle n of the large cone section 11 is 24.32 degrees. The cone 5 is an integral structure, also using a single injection molding of plastic material. Two table-shaped through-holes are formed inside the large cone section 11 and the small cone section 12 of the cone 5, which have the function of converging flow. In conjunction with the swirl guide 10, a swirl can be reliably formed, reducing interference between the horizontal pipe water flow and the vertical pipe water flow. The small cone section 12, due to its smaller cone angle, can be used as an installation component to facilitate the installation of the fire arrester ring 15. The socket, large cone section 11, small cone section 12 and the second riser interface 9 are a coaxial structure connected in sequence. The inner hollow body 2 has a cylindrical outer contour, with an outer diameter between 140 and 165 mm. If the outer diameter of the inner hollow body is too small, water entering the lateral branch will interfere with the drainage of the vertical pipe, resulting in poor ventilation and reduced drainage flow. If the outer diameter of the inner hollow body is too large, the cone 5 will be too long to maintain a certain taper, which will not only increase product material costs but also hinder the installation of the fire arrester ring 15. Keeping the outer diameter of the inner hollow body 2 between 140 and 165 mm can avoid these problems.

[0032] Furthermore, the outer side of the small cone section 12 is provided with a number of support portions 13 arranged at intervals, and the support portions 13 are arranged along the axis of the small cone section 12. The support portions 13 can support the installation of the fire-blocking ring 15. The small cone section 12 itself has a small cone angle, which is conducive to the installation of the support portion 13. At the same time, it can cooperate with the large cone section 11 to play a continuous flow-gathering role, facilitating the generation of swirl. Specifically, the shape of the support portion 13 is annular, and the outer diameter of all the support portions 13 is the same, and the outer diameter of the support portion 13 is between 124 and 126 mm. The support portion 13 of this size can be installed in conjunction with the 125-specification fire-blocking ring 15, and the supporting effect of the support portion 13 is reliable. In addition, the outer periphery of the large cone section 11 is provided with a number of water-blocking rings 14 that are integrated with the large cone section 11. The several water-blocking rings 14 are arranged at intervals to form multiple water-blocking, so that the tee can prevent water leakage after being cement-bonded with the floor slab 16.

[0033] In this embodiment, if Figure 2 and Figure 4As shown, the drainage interface 7 is arranged radially along the cone 5, and the distance from the connection between the large cone section 11 and the small cone section 12 to the lower edge of the drainage interface 7 is less than 100 mm. The thickness of the common floor 16 is 100 mm. The preferred size limit can ensure that the large cone section 11 is completely buried inside the floor 16 when the tee is installed. The first riser interface 3 is a socket with an inner diameter of 110 to 112 mm, which is compatible with the DN110 drainage pipe. The horizontal branch pipe interface 4 is a socket with an inner diameter of 110 to 112 mm, which is compatible with the DN110 drainage pipe. The second riser interface 9 is a socket with an inner diameter of 110 to 112 mm, which is compatible with the DN110 drainage pipe.
