Description
Technical Field
[0001] This utility model relates to the field of tee pipe technology, and in particular to a cavitation-resistant equal-diameter tee pipe. Background Technology
[0002] In industrial pipeline systems, equal diameter tees are widely used in fluid transportation, responsible for branching pipelines and distributing fluids. However, under many working conditions, such as in chemical and water conservancy industries, factors such as high-speed fluid flow, pressure changes, and chemical corrosion often lead to severe cavitation problems in equal diameter tees. Cavitation not only affects the normal operation of pipelines but also greatly shortens their service life, increases maintenance costs, and poses safety hazards. Therefore, developing a highly efficient and cavitation-resistant equal diameter tee is of great practical significance.
[0003] In addressing the cavitation problem of equal-diameter tees, existing technologies often employ ordinary metal materials to manufacture the tees, relying on the material's inherent corrosion resistance to resist cavitation. Structurally, they are mostly simple tee shapes, hoping to withstand fluid impact through conventional wall thickness design. The technical principle is mainly based on the material's tolerance to general corrosion under normal conditions, believing that as long as the material can withstand a certain degree of chemical erosion, it can maintain the normal use of the tee for a certain period of time.
[0004] However, existing technologies are severely inadequate in addressing cavitation problems at the branch points of equal-diameter tees. Due to the lack of structures that can optimize fluid flow, such as cavitation-resistant bushings, nozzles, and buffer components, fluid flow becomes turbulent at the tee branch points, making it difficult to effectively guide and buffer the flow. This results in drastic pressure changes, frequent cavitation, and rapid erosion of the pipe's inner wall, significantly impacting the service life and operational stability of equal-diameter tees. Therefore, a cavitation-resistant equal-diameter tee is proposed to solve these problems. Utility Model Content
[0005] To overcome the above deficiencies, this utility model provides a cavitation-resistant equal-diameter tee pipe, which aims to improve the problems of drastic pressure changes at the branch positions of existing equal-diameter tees, which lead to frequent cavitation, rapid corrosion of the inner wall of the pipe, shortened service life, and affected operational stability.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A cavitation-resistant equal-diameter tee pipe includes a tee pipe body, wherein a cavitation-resistant component is provided on the outer wall of the tee pipe body.
[0008] The cavitation-resistant component includes a protective sleeve that is slidably connected to the outer wall of the tee pipe body. A protective ring is fixedly connected to the inner wall of the protective sleeve and contacts the outer wall of the tee pipe body. A pair of symmetrical locking blocks are fixedly connected to the outer wall of the protective sleeve, and bolts are threaded into the locking blocks. The outer wall of the tee pipe body is coated with a metal coating, the outer wall of the metal coating is coated with a ceramic coating, the outer wall of the ceramic coating is coated with an organic coating, and a connecting component is provided on one side of the tee pipe body.
[0009] As a further description of the above technical solution:
[0010] The connecting assembly includes a first connecting ring and a second connecting ring, both of which are slidably connected to the outer wall of the tee pipe body.
[0011] As a further description of the above technical solution:
[0012] Both sides of the first connecting ring are fixedly connected to a first fixing block, and both sides of the second connecting ring are fixedly connected to a second fixing block.
[0013] As a further description of the above technical solution:
[0014] The second fixing block has a slot inside, and the first fixing block has a connecting shaft fixedly connected inside.
[0015] As a further description of the above technical solution:
[0016] A fixed shaft is fixedly connected to the bottom of the connecting shaft, and a transmission column is slidably connected inside the fixed shaft.
[0017] As a further description of the above technical solution:
[0018] An extrusion disc is fixedly connected to the outer wall of the transmission column.
[0019] As a further description of the above technical solution:
[0020] A rotating disk is fixedly connected to the top of the transmission column, and a locking column is fixedly connected to the outer wall of the transmission column, the locking column engaging with the locking groove.
[0021] As a further description of the above technical solution:
[0022] A spring is provided on the outer wall of the transmission column. One end of the spring is fixedly connected to the inner wall of the fixed shaft, and the other end is fixedly connected to the side wall of the extrusion disc.
[0023] This utility model has the following beneficial effects:
[0024] 1. In this utility model, the protective sleeve can reduce the wear of the protected object by external factors, the metal coating can form a metal covering layer on the surface of the tee pipe body, the ceramic coating can form a protective layer on the surface of the tee pipe body, enhancing the wear resistance and corrosion resistance of the object, and the organic coating can further form a protective film with good adhesion, flexibility and chemical resistance, thereby achieving a highly efficient cavitation resistance effect, solving the problem of serious erosion and damage to the inner wall of the pipe caused by the turbulent flow of fluid in the equal diameter tee pipe, and improving the operating efficiency of the equal diameter tee pipe in working conditions with cavitation risk.
[0025] 2. In this utility model, pressing the rotating disc causes the locking pin to engage inside the slot, thereby further squeezing the spring and causing it to deform elastically, providing a reverse force to the slot. Then, rotating the rotating disc causes the locking pin to deflect and lock, thus achieving the effect of quickly connecting pipes. This solves the problem that traditional pipe connection methods are cumbersome and time-consuming, and difficult to quickly complete the connection in emergency installation or maintenance scenarios, thereby improving the efficiency of pipe installation and maintenance.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figure 1 and Figure 2 The present invention provides an embodiment of a cavitation-resistant equal-diameter tee pipe, comprising a tee pipe body 1, wherein a cavitation-resistant component is provided on the outer wall of the tee pipe body 1, the cavitation-resistant component being used to provide cavitation-resistant performance for the tee pipe body 1.
[0034] The cavitation-resistant component includes a protective sleeve 2, which is slidably connected to the outer wall of the tee pipe body 1. The protective sleeve 2 provides physical protection to the outer wall of the tee pipe body 1. A protective ring 5, made of rubber, is fixedly connected to the inner wall of the protective sleeve 2 to provide elastic protection to the tee pipe body 1. The protective ring 5 contacts the outer wall of the tee pipe body 1. Symmetrical locking blocks 3 are fixedly connected to the outer wall of the protective sleeve 2. Bolts 4 are threaded inside the locking blocks 3. The protective sleeve 2 can be quickly installed by the cooperation of the locking blocks 3 and bolts 4. The outer wall of the tee pipe body 1 is coated with a metal coating 6. Utilizing the properties of metal, a metal covering layer is formed on the surface of the tee pipe body 1 to improve cavitation resistance. The performance and service life of the tee pipe body 1 are enhanced by the following: the outer wall of the metal coating 6 is provided with a ceramic coating 7. Utilizing the high hardness, high temperature resistance, oxidation resistance, and good chemical stability of ceramic materials, a protective layer is formed on the surface of the tee pipe body 1, enhancing its wear resistance, corrosion resistance, and high temperature resistance. An organic coating 8 is provided on the outer wall of the ceramic coating 7. By coating the surface of the tee pipe body 1 with organic materials, a protective film with good adhesion, flexibility, and chemical resistance is formed, preventing corrosion, improving appearance, and enhancing the weather resistance of the tee pipe body 1. A connecting component is provided on one side of the tee pipe body 1, which facilitates quick pipe connection by operators.
[0035] Specifically, when the equipment is in operation, large changes in fluid pressure can cause liquid vaporization and the generation of bubbles. These bubbles, upon bursting, can damage the component surface. The protective sleeve 2 primarily functions by providing excellent physical barrier properties to prevent external impurities from impacting the tee pipe body 1, reducing the risk of cavitation caused by mechanical damage. Through bolts 4 and locking blocks 3, the protective sleeve 2 can be quickly and securely installed on the tee pipe body 1, ensuring its effective protective function. The metal coating 6, as the basic protective layer, provides the tee pipe body 1 with excellent corrosion resistance and a certain degree of hardness. One line of defense resists the invasion of external corrosive substances, while the ceramic coating 7, with its high hardness and excellent wear resistance, can effectively cope with the powerful impact force and micro-jet scouring generated by the bursting of bubbles during cavitation, ensuring that the surface of the tee body 1 is not damaged and maintaining its long-term performance. At the same time, the organic coating 8, with its excellent chemical corrosion resistance and low coefficient of friction, can effectively isolate water vapor and other corrosive media, preventing other coatings from being eroded, while reducing fluid flow resistance and reducing the adhesion and aggregation of bubbles on the surface of the tee body 1, thereby improving the overall anti-cavitation performance.
[0036] Reference Figure 3 and Figure 4 The connecting assembly includes a first connecting ring 9 and a second connecting ring 10. Both the first connecting ring 9 and the second connecting ring 10 are slidably connected to the outer wall of the three-way pipe body 1. The function of the first connecting ring 9 and the second connecting ring 10 in the connecting assembly is to provide stable support and connection for the connecting assembly. A first fixing block 11 is fixedly connected to both sides of the first connecting ring 9, and a second fixing block 12 is fixedly connected to both sides of the second connecting ring 10. The second fixing block 12 has a slot 13 inside, which cooperates with other components to achieve the quick locking and unlocking function of the connecting assembly. A connecting shaft 14 is fixedly connected inside the first fixing block 11, and a fixing shaft 15 is fixedly connected to the bottom of the connecting shaft 14. The fixing shaft 15 provides connection and support, ensuring the stable movement of the assembly. The component is slidably connected to a transmission column 17, and a pressing disc 16 is fixedly connected to the outer wall of the transmission column 17. The function of the pressing disc 16 is to transmit power, thereby compressing the spring 19 to cause it to deform elastically. A rotating disc 20 is fixedly connected to the top of the transmission column 17. The function of the rotating disc 20 is to facilitate the user to quickly drive the movement of the component. A locking column 18 is fixedly connected to the outer wall of the transmission column 17. The locking column 18 fits into the locking groove 13. The cooperation between the locking column 18 and the locking groove 13 can ensure the stability of the component after connection. A spring 19 is provided on the outer wall of the transmission column 17. The function of the spring 19 is to provide elastic support for the component and at the same time provide a certain elastic restoring force. One end of the spring 19 is fixedly connected to the inner wall of the fixed shaft 15, and the other end is fixedly connected to the side wall of the pressing disc 16.
[0037] Specifically, in situations requiring frequent installation or modification of piping systems, emergency repair tasks, or strict time constraints for installation and construction, where pipe connections must be completed quickly, the user first aligns the external pipe with one side of the tee body 1. Then, by pressing the rotating disc 20, the drive column 17 slides inside the fixed shaft 15. This sliding action drives the locking column 18 into the slot 13, thus achieving the initial connection of the pipe. During the sliding of the drive column 17, it further drives the compression disc 16, which acts on the spring 19, causing it to undergo elastic deformation and store energy. When the user continues to rotate the rotating disc 20, the drive column 17 pushes the locking column 18 to rotate inside the slot 13, and through the reverse pulling force of the spring 19, the outer wall of the locking column 18 tightly adheres to the inner wall of the slot 13, thereby achieving rapid locking and ensuring a stable connection of the pipe.
[0038] Working Principle: When using this tee pipe, the protective sleeve 2, through its physical barrier properties, reduces the impact of external impurities on the tee pipe body 1, lowering the risk of cavitation caused by mechanical damage. The protective sleeve 2 can be quickly installed using bolts 4 and locking blocks 3. The metal coating 6, with its good corrosion resistance and certain hardness, provides basic protection for the tee pipe body 1. The ceramic coating 7, with its high hardness and excellent wear resistance, effectively resists the strong impact force and micro-jet erosion generated by bubble bursting during cavitation. The organic coating 8, with its good chemical corrosion resistance and low coefficient of friction, isolates water vapor and corrosive media, preventing other coatings from being eroded. It also reduces fluid flow resistance and reduces the adhesion and aggregation of bubbles on the surface of the tee pipe body 1, thereby achieving high efficiency. The cavitation resistance is achieved during pipe connection. First, the user places the external pipe against one side of the tee body 1. Then, by pressing the rotating disc 20, the transmission column 17 slides inside the fixed shaft 15. The sliding of the transmission column 17 further drives the locking column 18 to engage with the slot 13. Simultaneously, the sliding of the transmission column 17 further drives the compression disc 16 to compress the spring 19, causing the spring 19 to elastically deform and store the deformation. Then, by rotating the rotating disc 20, the user drives the locking column 18 to rotate within the slot 13. The elastic deformation of the spring 19 provides a reverse pulling force to the locking column 18, ensuring a tight fit between the outer wall of the locking column 18 and the slot 13, thus achieving quick locking and facilitating rapid pipe connection.
