Description

Technical Field

[0001] This application belongs to the field of fluid transportation, and in particular relates to a novel spherical tee. Background Technology

[0002] In fire-fighting equipment, to improve fire extinguishing efficiency, "bubble water" is often created by injecting gas (such as air or inert gas) into the water to form uniformly distributed microbubbles. This type of gas-liquid mixture significantly enhances fire extinguishing effectiveness through mechanisms such as foam coverage, oxygen isolation, and lowering the ignition temperature. However, the flow channel design of traditional T-junctions can cause localized low-pressure zones as the fluid passes through, causing bubbles to rise, coalesce, and eventually form larger bubbles, or even lead to gas-liquid stratification. This not only reduces the fire extinguishing performance of bubble water (damaging foam stability and coverage uniformity) but may also cause pipeline pressure fluctuations due to airlock, affecting the reliability of the fire protection system. Therefore, it is necessary to solve these technical problems. Utility Model Content

[0003] The purpose of this application is to provide a novel spherical tee to solve the technical problem of easy gas-liquid stratification in fire-fighting bubble water in the prior art.

[0004] To achieve the above objectives, the technical solution adopted in this application is: to provide a novel spherical tee, comprising:

[0005] A sphere, forming a spherical inner cavity;

[0006] A water inlet is connected to the sphere and forms a water inlet communicating with the inner cavity of the sphere;

[0007] A water outlet is provided at an interval from the water inlet and connected to the sphere, and the water outlet forms a water outlet communicating with the inner cavity of the sphere;

[0008] A rotating ring is disposed in the channel of the spherical inner cavity for connecting the water outlet and is coaxially arranged with the water outlet. Several spiral blades are also formed on the inner side wall of the rotating ring along its own radial direction and are evenly distributed around its own central axis. The spiral blades are formed in a preset shape and can make the rotating ring rotate around its own central axis relative to the sphere when the water flows through the rotating ring.

[0009] Optionally, two sets of water outlet interfaces are provided corresponding to the rotating ring.

[0010] The two water outlets are arranged opposite each other on the sphere and form two coaxial water outlets facing away from each other. The two rotating rings corresponding to the two water outlets have helical blades with opposite directions of rotation.

[0011] The novel spherical tee also includes support rods at both ends connected to the rotating ring, the support rods being parallel to the axial direction of the rotating ring.

[0012] Optionally, multiple support rods are evenly arranged around the central axis of the rotating ring.

[0013] Optionally, the rotating ring and the support rod are integrally injection molded.

[0014] Optionally, the novel spherical tee further includes a retaining ring that abuts coaxially against the rotating ring;

[0015] The retaining ring is connected to the sphere, and the support rod and the rotating ring connected to both ends of the support rod are clamped between the retaining ring.

[0016] Optionally, the retaining ring is threadedly connected to the sphere.

[0017] Optionally, the retaining ring is welded to the sphere;

[0018] A step is formed on the sphere that abuts against the retaining ring along the axial direction of the retaining ring.

[0019] Optionally, a flow channel is formed between the water inlet and / or the water outlet and the spherical inner cavity;

[0020] The flow channel forms a straight hole section and a tapered opening section. The straight hole section is disposed between the spherical inner cavity and the tapered opening section, and the tapered opening section forms a flared end away from the straight hole section.

[0021] The novel spherical tee provided in this application has the following advantages: Compared with the prior art, in the novel spherical tee provided in this application, the inlet and outlet ports connected to the sphere form an inlet and an outlet respectively communicating with the spherical inner cavity of the sphere. Because the rotating ring set in the channel within the spherical inner cavity for connecting the outlet is coaxially arranged with the outlet, and because several spiral blades formed on the inner wall of the rotating ring can rotate under the action of the water flow, causing the rotating ring to rotate relative to the sphere around its own central axis, the rotating ring can fully disperse the water flow through its spiral blades, making it difficult for air bubbles in the water flow to aggregate and grow larger. Therefore, the novel spherical tee provided in this application can effectively solve the problem of easy gas-liquid stratification in fire-fighting bubble water, which is far superior to the prior art.

[0031] Please refer to the following: Figures 1 to 3 This application provides a novel spherical tee according to an embodiment. The novel spherical tee includes a sphere 100, an inlet port 200, an outlet port 300, and a rotating ring 400. Wherein:

[0032] The sphere 100 forms a spherical inner cavity 101; the water inlet 200 is connected to the sphere 100 and forms a water inlet 201 communicating with the spherical inner cavity 101; the water outlet 300 is spaced apart from the water inlet 200 and connected to the sphere 100, forming a water outlet 301 communicating with the spherical inner cavity 101; the rotating ring 400 is disposed in the channel of the spherical inner cavity 101 for communicating with the water outlet 301 and is coaxially arranged with the water outlet 301. The rotating ring 400 also forms a plurality of spiral blades 401 evenly distributed around its central axis on its inner wall along its radial direction. The spiral blades 401 form a preset shape and enable the rotating ring 400 to rotate relative to the sphere 100 around its central axis when water flows through it. The preset shape formed by the spiral blades 401 in this application can adopt a shape commonly used in the art that can agitate water flow, which will not be elaborated further here.

[0033] According to the structure provided in this embodiment, in the novel spherical tee provided in this embodiment, the inlet port 200 and the outlet port 300 connected to the sphere 100 respectively form an inlet port 201 and an outlet port 301 communicating with the spherical inner cavity 101 on the sphere 100. Since the rotating ring 400, which is disposed in the channel within the spherical inner cavity 101 for communicating with the outlet port 301, is coaxially arranged with the outlet port 301, and since several spiral blades 401 formed on the inner wall of the rotating ring 400 can rotate under the action of water flow and drive the rotating ring 400 to rotate relative to the sphere 100 around its own central axis, the rotating ring 400 can fully disperse the water flow through its spiral blades 401, making it difficult for air bubbles in the water flow to aggregate and grow larger. Therefore, the novel spherical tee provided in this embodiment can effectively solve the problem of easy gas-liquid stratification in fire-fighting bubble water, which is far superior to the prior art.

[0034] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 3Two sets of water outlet interfaces 300 and rotating rings 400 are correspondingly provided. According to the structure provided in this embodiment, each water outlet 301 of the novel spherical tee provided in this embodiment is correspondingly provided with a rotating ring 400 that can disperse the water flow. This allows the novel spherical tee in this embodiment to better solve the problem of easy gas-liquid stratification in fire-fighting bubble water.

[0035] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 3 Two water outlets 300 are arranged opposite each other on the sphere 100, forming two coaxial outlets 301 facing away from each other. Two rotating rings 400 corresponding to the two outlets 301 have helical blades 401 with opposite directions of rotation. The novel spherical tee also includes support rods 500 connected at both ends to the rotating rings 400, with the support rods 500 parallel to the axial direction of the rotating rings 400. According to the structure provided in this embodiment, since the two rotating rings 400 corresponding to the two outlets 301 have helical blades 401 with opposite directions of rotation, the support rods 500 connected between the two rotating rings 400 and parallel to the axial direction of the rotating rings 400 can be driven by the rotating rings 400 to rotate around the central axis of the rotating rings 400. This allows the water flow inside the spherical inner cavity 101 to be fully agitated by the support rods 500, which also enables the novel spherical tee in this embodiment to better solve the problem of easy gas-liquid stratification in fire-fighting bubble water.

[0036] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 3 Multiple support rods 500 are evenly arranged around the central axis of the rotating ring 400. According to the structure provided in this embodiment, the multiple support rings arranged around the central axis of the rotating ring 400 can more fully agitate the water flow inside the spherical inner cavity 101, which also enables the novel spherical tee in this embodiment to better solve the problem of easy gas-liquid stratification of fire-fighting bubble water.

[0037] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 3The rotating ring 400 and the support rod 500 are integrally injection molded. According to the structure provided in this embodiment, the integrally injection molded rotating ring 400 and support rod 500 can form a more stable connection, thus enabling the novel spherical tee in this embodiment to better solve the problem of easy gas-liquid stratification in fire-fighting bubble water. It is understood that in this embodiment, the rotating ring 400 and support rod 500 can be integrally injection molded using engineering plastics or nylon, resulting in a lighter weight and easier rotation. Furthermore, in some other embodiments of this application, the support rod 500 and rotating ring 400 can be detachably connected, allowing for easy replacement when the rotating ring 400 or support rod 500 becomes worn. In specific implementation, the connection method of the rotating ring 400 and support rod 500 can be flexibly set according to actual needs, and will not be elaborated further here.

[0038] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 3 The novel spherical tee also includes a retaining ring 600 coaxially abutting against the rotating ring 400; the retaining ring 600 is connected to the sphere 100, and the support rod 500 and the rotating ring 400 connected to both ends of the support rod 500 are clamped between the retaining rings 600. According to the structure provided in this embodiment, the two retaining rings 600 connected to the sphere 100 can effectively limit the axial movement of the rotating ring 400 and the support rod 500 along the rotating ring 400, thus enabling the novel spherical tee in this embodiment to better solve the problem of easy gas-liquid stratification in fire-fighting bubble water.

[0039] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 3 The retaining ring 600 is threadedly connected to the ball 100. According to the structure provided in this embodiment, the retaining ring 600 threadedly connected to the ball 100 can be easily removed from the ball 100, which facilitates the replacement and maintenance of the rotating ring 400 and the support rod 500. This also helps the new spherical tee in this embodiment to better solve the problem of easy gas-liquid stratification in fire-fighting bubble water.

[0040] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 3 The retaining ring 600 is welded to the sphere 100; a step 102 is formed on the sphere 100 along the axial direction of the retaining ring 600, abutting against the retaining ring 600. According to the structure provided in this embodiment, the welding relationship between the retaining ring 600 and the sphere 100, and the step 102 formed on the sphere 100 for abutting against the retaining ring 600, can create a more stable connection between the retaining ring 600 and the sphere 100. This also makes the installation position of the rotating ring 400 more stable and helps the novel spherical tee in this embodiment better solve the problem of easy gas-liquid stratification in fire-fighting bubble water.

[0041] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 3 A flow passage 700 is formed between the inlet 201 and / or the outlet 301 and the spherical inner cavity 101; the flow passage 700 forms a straight hole section 701 and a conical mouth section 702, the straight hole section 701 is disposed between the spherical inner cavity 101 and the conical mouth section 702, and the conical mouth section 702 forms a flared end away from the straight hole section 701. According to the structure provided in this embodiment, the flow passage 700 formed between the inlet 201 or the outlet 301 and the spherical inner cavity 101 can connect the inlet 201 or the outlet 301 to the spherical inner cavity 101. Since the flow passage 700 forms a straight hole section 701 and a conical opening section 702, and the conical opening section 702 forms an flared end away from the straight hole section 701, a better self-sealing effect can be formed when connected to an external pipe through the conical opening section 702. This also enables the new spherical tee in this embodiment to better solve the problem of easy gas-liquid stratification of fire-fighting bubble water.

[0042] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
