Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a pressure-resistant reducer. Background Technology
[0002] A pressure reducer is a type of irregularly shaped connector used in piping systems. Its core feature is that the two ends have different diameters and it has enhanced structural strength to withstand higher pressures.
[0003] The prior art patent document CN216046026U discloses a large-diameter pipe, a connecting pipe, and a small-diameter pipe. A connecting pipe is fixed to one side of the large-diameter pipe, and a rubber layer is fixed to the inner wall of the connecting pipe. Elastic protrusions are fixed to the inner wall of the rubber layer. A reinforcing structure is fixed inside the connecting pipe. A small-diameter pipe is fixed to one side of the connecting pipe, and sealing structures are provided on the inner walls of both the small-diameter and large-diameter pipes. This utility model, by incorporating a rubber layer, mitigates the impact force of water flow when water flows from the large-diameter pipe through the connecting pipe to the small-diameter pipe. The rubber layer, fixed to the inner wall of the connecting pipe, reduces the impact force. Furthermore, the elastic protrusions, evenly distributed within the rubber layer, disperse the impact force, improving the pressure resistance of the connecting pipe.
[0004] Traditional reducers require connection to pipelines via welding, threaded fastening, or flange bolts. These methods demand high precision (e.g., welding requires aligned bevels and no pores, threaded connections require sealing tape or sealant) and rely on specialized tools (such as welding machines and torque wrenches) and skilled workers, resulting in lengthy connection times for a single pipeline. In large-scale projects (such as chemical plants and long-distance pipelines), the installation of numerous reducers significantly extends the construction period and increases labor costs. Therefore, a pressure-resistant reducer is proposed to address these issues. Utility Model Content
[0005] The purpose of this utility model is to provide a pressure-resistant reducer, which solves the problem of inconvenience in disassembling and cleaning mixing equipment.
[0006] To achieve the above objectives, this utility model provides a pressure-resistant reducer, including a reducing pipe, wherein a connecting mechanism is fixedly connected to the bottom of the reducing pipe, and a sealing mechanism is fixedly connected inside the reducing pipe; The connecting mechanism includes a connecting pipe, the top of which is fixedly connected to the bottom of the reducing pipe, a limiting ring fixedly connected to the outside of the connecting pipe, a spring fixedly connected to the outside of the connecting pipe, a slip ring slidably connected to the outside of the connecting pipe, a connecting pipe slidably connected to the inside of the connecting pipe, and a limiting component rotatably connected to the inside of the connecting pipe.
[0007] The sealing mechanism includes a connecting gasket, which is externally fixedly connected to the inner wall of the reducing pipe. Multiple rubber rings are externally fixedly connected to the connecting gasket, and a rubber ring is internally fixedly connected to the reducing pipe.
[0008] The limiting component includes a ball bearing, which is rotatably connected inside the connecting pipe, and a limiting groove is provided on the outside of the connecting pipe.
[0009] The outer part of the ball is rotatably connected to the inner wall of the limiting groove, and the outer part of the ball is rotatably connected to the inside of the slip ring.
[0010] The slip ring is internally fixedly connected to one end of the spring, and externally slidably connected to the outside of the limiting ring.
[0011] The connecting pipe is fixedly connected to the outside of a sealing ring, and the outside of the sealing ring is slidably connected to the inside of the connecting pipe.
[0012] The limiting ring is made of rubber, and the rubber ring is made of rubber.
[0013] The reducing pipe is internally fixedly connected with carbon steel, and one end of the connecting gasket is fixedly connected to the outside of the rubber ring.
[0014] This utility model relates to a pressure-resistant reducer, which, through... 1. The present invention greatly improves the ease of installation. Through the cooperation of slip rings, springs and ball bearings, the connecting pipe and connecting tube can be quickly fixed and disassembled without the need for complicated tools and professional technicians, thus shortening the construction cycle and reducing labor costs. It is especially suitable for the batch installation needs in large-scale projects.
[0015] 2. In this utility model, the sealing performance is comprehensively enhanced. The sealing ring on the connecting pipe fills the connection gap, and the rubber ring and rubber ring inside the reducing pipe form a multiple seal under the support of the connecting pad. Combined with the auxiliary sealing effect of the limiting ring, it effectively prevents high-pressure medium leakage and reduces safety hazards. Attached Figure Description

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0020] Please see Figures 1-4 This utility model provides a technical solution: a pressure-resistant reducer, including a reducer 1, with a connection mechanism 2 fixedly connected to the bottom of the reducer 1 for realizing quick pipe connection and fixation. This mechanism can greatly improve installation efficiency. A sealing mechanism 3 is fixedly connected inside the reducer 1 to enhance the sealing of the pipe connection and reduce the risk of medium leakage. The connecting mechanism 2 includes a connecting pipe 21 as the docking base carrier. The top of the connecting pipe 21 is fixedly connected to the bottom of the reducing pipe 1, providing structural support for the docking of the reducing pipe 1 with other pipes. The connecting pipe 21 is fixedly connected to a limiting ring 22 that limits and guides the slip ring 24, preventing the slip ring 24 from deviating from the preset trajectory when sliding. The connecting pipe 21 is fixedly connected to a spring 23 that provides elastic restoring force, ensuring that the slip ring 24 automatically resets when no external force is applied. The connecting pipe 21 is slidably connected to a slip ring 24 for controlling the state of the limiting component 26. The docking fixed state can be adjusted by sliding the slip ring 24. The connecting pipe 21 is slidably connected to a connecting pipe 25 for achieving pipe diameter transition docking with external pipes, realizing precise connection of pipes with different diameters. The connecting pipe 21 is rotatably connected to a limiting component 26 for fixing the position of the connecting pipe 25, ensuring the stability of the pipes after docking. The limiting component 26 includes a rollable ball 261, which is rotatably connected inside the connecting tube 21. The rolling characteristic reduces the frictional resistance during docking. The outside of the connecting tube 25 is provided with a limiting groove 262 that mates with the ball 261. When the ball 261 is inserted into the limiting groove 262, the connecting tube 25 and the connecting tube 21 can be fixed. The outer rotatable connection of the ball 261 is connected to the inner wall of the limiting groove 262. The engagement of the two achieves the axial fixation of the connecting tube 25. The outer rotatable connection of the ball 261 is connected to the inside of the slip ring 24. When the slip ring 24 is in the initial position, its inner wall abuts against the ball 261 to make it stably engage in the limiting groove 262, ensuring a firm connection. like Figure 2 and Figure 4 As shown, the sealing mechanism 3 includes a connecting pad 31 that provides support and sealing assistance. The connecting pad 31 is externally fixedly connected to the inner wall of the reducing pipe 1, providing an installation base for the sealing components. The connecting pad 31 is externally fixedly connected to multiple rubber rings 32 that can increase the friction of the pipe connection, effectively preventing the pipe from falling off due to vibration or pressure fluctuations after connection. The reducing pipe 1 is internally fixedly connected to a rubber ring 33 that further enhances the internal sealing of the pipe, reducing the possibility of medium leakage from the gaps in the inner wall of the reducing pipe 1. The limiting ring 22 is made of rubber. The elastic properties of rubber can buffer the impact force when the slip ring 24 slides, and at the same time enhance the stability of the slip ring 24 when sliding. The rubber ring 32 is made of rubber. Utilizing the high coefficient of friction of rubber, it increases the friction of the joint after the pipe is connected, effectively preventing the pipe from falling off due to vibration or pressure impact. The internal fixed connection of the reducer 1 is carbon steel 4, which has high structural strength and can significantly enhance the overall pressure resistance of the reducer 1, providing structural support for the stable operation of the pipeline system under high pressure conditions. One end of the connecting gasket 31 is fixedly connected to the outside of the rubber ring 33. Through the supporting effect of the connecting gasket 31, the installation stability of the rubber ring 33 can be enhanced, ensuring that it continues to play a sealing role.
[0021] like Figures 1-4 The slip ring 24 shown is internally fixedly connected to one end of the spring 23. When the slip ring 24 is slidable, the spring 23 will be compressed. After it is released, the elastic force of the spring 23 can drive the slip ring 24 to automatically reset. The slip ring 24 is externally slidably connected to the outside of the limiting ring 22. The limiting ring 22 guides the sliding trajectory of the slip ring 24 to prevent it from deviating and affecting the control effect of the ball 261. The external fixed connection of the connecting pipe 25 has a sealing ring 263 to enhance the sealing of the mating joint. The sealing ring 263 is externally slidably connected to the inside of the connecting pipe 21. When the connecting pipe 25 and the connecting pipe 21 are mated, the sealing ring 263 can fill the gap between them and reduce the risk of the medium flowing out from the connection.
[0022] Working principle: When using this pressure reducing pipe, first pick up the reducing pipe 1, manually slide the slip ring 24 on the outside of the connecting pipe 21. The slip ring 24 slides along the outside of the limiting ring 22 and compresses the spring 23. At this time, the inner wall of the slip ring 24 no longer presses against the ball 261 in the connecting pipe 21. The ball 261 disengages from the limiting groove 262 on the outside of the connecting pipe 25, releasing the fixed restriction on the connecting pipe 25, making it easier to insert the connecting pipe 25 into the connecting pipe 21 to complete the initial docking. After the docking is completed, the slip ring 24 is released. The elastic restoring force of the spring 23 pushes the slip ring 24 back to its original position. Its inner wall presses against the ball 261 again, forcing the ball 261 to be inserted into the limiting groove 262, thus achieving a firm fixation between the connector 25 and the connecting pipe 21. At the same time, the sealing ring 263 on the outside of the connector 25 fits tightly against the inner wall of the connecting pipe 21, initially blocking the medium leakage path. The sealing mechanism 3 inside the reducer 1 further enhances the sealing performance: the rubber ring 32 made of rubber is fixed to the inner wall of the reducer 1 through the connecting gasket 31, which increases the friction between the pipes during docking and prevents them from falling off; the rubber ring 33 fits tightly against the pipe under the support of the connecting gasket 31, and together with the overall strength of the reducer 1 reinforced by carbon steel 4, it ensures the sealing stability under high pressure conditions.
[0023] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
