Description

Technical Field

[0001] The utility model relates to the technical field of pipe fittings, in particular to an impact-resistant elbow pipe fitting. Background Art

[0002] The application range of pipe fittings is very wide. According to the connection method, pipe fittings can be divided into four categories: socket pipe fittings, threaded pipe fittings, flange pipe fittings and welded pipe fittings. Different pipe fittings have different uses. For example, elbow pipe fittings are mainly used at the places where the pipeline turns. The elbow pipe fittings set at this place are subject to greater impact force and are also the places most likely to be damaged.

[0003] However, the elbow pipe fittings in the prior art generally have the following problems: most of them are a single elbow pipe, with a relatively simple structure. The elbow part is subject to long-term impact and cavitation of water flow, which easily leads to the rupture of the elbow part. And if the water flow impact force is large, such as when the water hammer effect occurs, it is also easy to cause the rupture of the elbow part. In order to improve it, an impact-resistant elbow pipe fitting is proposed here. Content of the Utility Model

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and an impact-resistant elbow pipe fitting is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An impact-resistant elbow pipe fitting includes an elbow pipe. A flange is provided on the elbow pipe. A hanging frame is provided on the flange through a hanging groove. A fixing frame is commonly provided on a plurality of the hanging frames. A fan blade assembly is rotatably provided on the fixing frame. An extrusion groove is provided on the flange. A positioning block is provided in the extrusion groove through an extrusion mechanism. A positioning hole is provided on the hanging frame.

[0007] Preferably, the extrusion mechanism includes a spring provided in the extrusion groove. Two ends of the spring are elastically connected to the outer wall of the positioning block and the inner wall of the extrusion groove respectively.

[0008] Preferably, one side outer wall of the positioning block is inclined, and an inclined contact groove is provided on the hanging frame.

[0009] Preferably, a rotating shaft fixedly connected to the fan blade assembly is rotatably penetrated through the fixing frame, and a plurality of stirring rods are fixedly installed on the rotating shaft.

[0010] Preferably, a plurality of the stirring rods are all welded on the rotating shaft, and the plurality of stirring rods are circumferentially equidistantly distributed relative to the rotating shaft.

[0011] Preferably, the thickness of the part of the hanging frame in the hanging groove is the same as the depth of the hanging groove, and the hanging frame is sealed and installed in the hanging groove.

[0012] Advantages of the present utility model:

[0013] 1. Hanging slots are provided on the flange, and multiple hanging brackets are connected to the flange through the hanging slots. This connection method is convenient, fast, stable and reliable. Multiple hanging brackets jointly support the fixing frame, making the whole structure more firm.

[0014] 2. The thickness of the part of the hanging bracket in the hanging slot is the same as the depth of the hanging slot, ensuring a tight and seamless connection, and further enhancing the stability of the structure.

[0015] 3. The extrusion mechanism on the flange consists of a spring and a positioning block. When the hanging bracket is inserted into the hanging slot, the contact slot squeezes the positioning block to compress the spring. After the hanging bracket is completely inserted, the positioning block enters the positioning hole under the action of the spring force of the spring, realizing the fixation of the hanging bracket. This mechanism is simple to operate and has a good fixation effect, effectively preventing the hanging bracket from loosening or falling off during use.

[0016] 4. The fan blade assembly on the fixing frame rotates under the action of the fluid, playing a role in buffering and regulating the flow rate, and improving the operation stability of the pipeline system.

[0017] 5. The stirring rod on the stirring shaft rotates with the fan blade assembly when the fluid passes through, stirring and mixing the fluid, improving the fluid mixing effect, reducing impurity precipitation, preventing blockage inside the elbow pipe, and at the same time improving the impact resistance and service life of the elbow pipe.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0025] Referring to Figures 1-5

[0026] This impact-resistant elbow pipe fitting is mainly composed of an elbow pipe 1 and a flange 2. The elbow pipe 1 plays a role in changing the flow direction of the fluid and has a wide application in various pipeline systems. The flange 2 is connected to the elbow pipe 1, providing a basis for subsequent installation of other components.

[0027] The flange 2 is provided with a hanging groove 4, and multiple hanging brackets 5 can be connected to the flange 2 through the hanging groove 4. This connection method is both convenient and stable. Multiple hanging brackets 5 jointly support the fixing frame 6, making the entire structure more firm and reliable.

[0028] A fan blade assembly 7 is rotatably provided on the fixing frame 6. When the fluid passes through the elbow pipe 1, the fan blade assembly 7 can rotate under the action of the fluid, playing a role in buffering and regulating the flow rate to a certain extent.

[0029] The extrusion mechanism arranged in the extrusion groove 10 on the flange 2 is mainly composed of a spring 14 and a positioning block 11. The two ends of the spring 14 are elastically connected to the outer wall of the positioning block 11 and the inner wall of the extrusion groove 10 respectively. When the hanging bracket 5 is inserted into the hanging groove 4, the inclined contact groove 12 on the hanging bracket 5 will contact the inclined part on one side outer wall of the positioning block 11. As the hanging bracket 5 continues to be inserted, the contact groove 12 will squeeze the positioning block 11, causing the positioning block 11 to compress the spring 14 and move into the extrusion groove 10. After the hanging bracket 5 is completely inserted into the hanging groove 4, the positioning block 11 is pushed out under the elastic force of the spring 14 and finally squeezed into the positioning hole 13 on the hanging bracket 5, thus realizing the fixation of the hanging bracket 5. This extrusion mechanism is not only simple to operate but also has a good fixing effect, effectively preventing the hanging bracket 5 from loosening or falling off during use.

[0030] A rotating shaft 8 is rotatably penetrated through the fixing frame 6, and the rotating shaft 8 is fixedly connected to the fan blade assembly 7. When the fluid passes through the elbow pipe 1, the rotation of the fan blade assembly 7 will drive the rotating shaft 8 to rotate together. A plurality of stirring rods 9 are fixedly installed on the rotating shaft 8, and these stirring rods 9 can stir and mix the fluid under the drive of the rotating shaft 8. The plurality of stirring rods 9 are welded to the rotating shaft 8 and are circumferentially equally spaced relative to the rotating shaft 8, which can ensure the uniformity of stirring. The function of the stirring rods 9 can not only improve the mixing effect of the fluid but also reduce the precipitation of impurities in the fluid, prevent blockage inside the elbow pipe 1, and improve the impact resistance and service life of the elbow pipe 1.

[0031] The thickness of the part of the hanging bracket 5 located within the hanging groove 4 is the same as the depth of the hanging groove 4, which can ensure a tight and seamless connection between the hanging bracket 5 and the hanging groove 4. The hanging bracket 5 is sealed and installed within the hanging groove 4, which can prevent fluid leakage and improve the sealing performance of the elbow pipe 1. This sealed connection method can also reduce the corrosion of the hanging bracket 5 and the hanging groove 4 by the fluid, extend the service life of the elbow pipe 1. At the same time, the sealed installation can also improve the safety and reliability of the entire pipeline system and prevent accidents caused by leakage.

[0032] When the present utility model is in use, when the fluid flows in the pipeline system and enters the elbow pipe 1, the fluid changes its flow direction through the elbow pipe 1. Due to the flow action of the fluid, the fan blade assembly 7 on the fixing bracket 6 is pushed by the fluid and starts to rotate. The rotation of the fan blade assembly 7 drives the rotating shaft 8 fixedly connected thereto to rotate together, and multiple stirring rods 9 on the rotating shaft 8 also rotate accordingly. The stirring rods 9 stir and mix the fluid passing through the elbow pipe 1, improve the mixing effect of the fluid, and at the same time reduce the sedimentation of impurities in the fluid to prevent blockage inside the elbow pipe 1.

[0033] During the installation process, the hanging bracket 5 is inserted into the hanging groove 4 on the flange 2. When the hanging bracket 5 is inserted, the inclined contact groove 12 on the hanging bracket 5 contacts the inclined part of the outer wall of one side of the positioning block 11 within the extrusion groove 10. As the hanging bracket 5 continues to be inserted, the contact groove 12 presses the positioning block 11, causing the positioning block 11 to compress the spring 14 and move into the extrusion groove 10. After the hanging bracket 5 is completely inserted into the hanging groove 4, the positioning block 11 is pushed out under the elastic force of the spring 14 and finally presses into the positioning hole 13 on the hanging bracket 5 to achieve the fixation of the hanging bracket 5. Multiple hanging brackets 5 jointly support the fixing bracket 6 to ensure the firmness and reliability of the entire structure.

[0034] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
