Abstract
Description
Technical Field
[0001] This utility model relates to the field of steam turbines, and in particular to a heating unit with improved reliability. Background Technology
[0002] A steam turbine, also known as a steam engine, is a rotary steam power unit. High-temperature, high-pressure steam passes through a fixed nozzle, becomes an accelerated airflow, and is then injected onto the blades, causing the rotor, which is equipped with rows of blades, to rotate and perform work. Steam turbines are the main equipment in modern thermal power plants and are also used in the metallurgical industry, chemical industry, and ship propulsion systems.
[0003] Now, the steam turbine will adjust the thrust of the unit by replacing components such as the rotor and diaphragms through the extraction steam pipeline and desuperheating and pressure reducing device, and by modifying the high and medium pressure flow path. This will ensure that the hot re-extraction steam capacity is increased to 100t / h.
[0004] When the extraction pipe is shut down, air enters the pipe and combines with residual moisture to form oxygen corrosion, causing the inner wall to rust. At the same time, the steam contains trace amounts of CO2 and SO2, forming an acidic medium that corrodes the carbon steel pipe. The extraction pipe needs to be maintained regularly. However, the extraction pipe is fixed to the support with multiple bolts, which makes it inconvenient to disassemble and install the extraction pipe later.
[0005] Therefore, it is necessary to provide a heating unit with improved reliability to solve the above-mentioned technical problems. Utility Model Content

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0025] First Embodiment
[0026] Please refer to the following: Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of a heating unit for improving reliability provided by this utility model; Figure 2 for Figure 1 A cross-sectional structural schematic diagram of the fixing clamp shown; Figure 3 for Figure 2 The enlarged schematic diagram of part A is shown. A heating unit with improved reliability includes: a bracket 1, a fixing clamp 2, an anti-slip pad 3, a fixing device 4, and an extraction pipe 6;
[0027] The fixing clip 2 is disposed on the top of the bracket 1, the anti-slip pad 3 is fixedly installed on the inner wall surface of the fixing clip 2, and the fixing clip 2 is provided with a steam extraction pipe 6 inside;
[0028] The fixing device 4 includes a positioning pin 41, a fixing groove 42, a fixing pin 43, a reset member 44, and a plurality of fixing holes 45. One end of the positioning pin 41 is fixedly connected to the top of the bracket 1. The fixing groove 42 is opened inside the fixing clamp 2. The fixing pin 43 is slidably connected inside the fixing groove 42. The reset member 44 is disposed inside the fixing groove 42. The plurality of fixing holes 45 are all opened in the positioning pin 41.
[0029] The bottom of one end of the fixing pin 43 is arc-shaped, which is used to automatically move the fixing pin 43 to one side along the arc shape when the fixing clamp 2 moves downward.
[0030] The anti-slip pad 3 is made of rubber and is used to protect the space between the fixing clip 2 and the extraction pipe. At the same time, by compressing and deforming the rubber, it works with the fixing pin 43 and the fixing hole 45 to limit the space between the fixing clip 2 and the bracket 1.
[0031] The anti-slip pads 3 are fixedly installed on the inner wall surfaces of both the bracket 1 and the fixing clamp 2.
[0032] The reset element 44 is a spring, which is disposed inside the fixing groove 42 and located at one end of the fixing pin 43.
[0033] The reset element 44 can also be a spring.
[0034] The working principle of the heating unit with improved reliability provided by this utility model is as follows:
[0035] When in use, the extraction pipe is placed inside the bracket 1.
[0036] After the pin hole inside the fixing clip 2 is fitted onto the surface of the two positioning pins 41, when the fixing clip 2 is moved downward, the inclined surface of the fixing pin 43 moves to one side inside the fixing hole 45 and separates, thereby pressing the reset member 44 while moving to one side inside the fixing groove 42. When the fixing pin 43 moves to the position of the next fixing hole 45, the reset member 44 pushes the fixing pin 43 to one side inside the fixing groove 42, so that the fixing pin 43 is inserted into the fixing hole 45. After repeating the above steps, the fixing clip 2 is moved to the appropriate position, and after the fixing pin 43 is inserted into the fixing hole 45, the fixing clip 2 and the bracket 1 are limited.
[0037] Compared with related technologies, the heating unit with improved reliability provided by this utility model has the following beneficial effects:
[0038] This utility model provides a heating unit with improved reliability. After the fixing clip 2 is inserted into the fixing device 4 on the bracket 1, the fixing clip 2 and the bracket 1 are fixed together by the anti-slip pad 3 and the fixing device 4, which facilitates the quick and easy fixing of the fixing clip 2 and the bracket 1, and facilitates the installation and disassembly of the steam extraction pipe.
[0039] Second Embodiment
[0040] Please refer to the following: Figure 4 and Figure 5 Based on the first embodiment of this application which provides a heating unit with improved reliability, the second embodiment of this application proposes another heating unit with improved reliability. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.
[0041] Specifically, the second embodiment of this application provides a heating unit with improved reliability, which differs in that it also includes a limiting device 5, which is disposed inside the fixing pin 43 and is used to limit the distance between the fixing pin 43 and the fixing clamp 2.
[0042] The limiting device 5 can be a buckle, lock, etc., used to limit the movement between the fixing pin 43 and the fixing clamp 2.
[0043] The limiting device 5 includes a limiting groove 51, a limiting pin 52, and a limiting hole 53. The limiting groove 51 is opened inside the fixing pin 43, the limiting pin 52 is slidably connected to the inside of the limiting groove 51, and the limiting hole 53 is opened inside the fixing clamp 2.
[0044] After the limiting pin 52 is inserted into the limiting hole 53, it limits the fixing pin 43, thereby increasing the stability of the fixing pin 43 when it is limited.
[0045] The limiting device 5 also includes a limiting ring 54 and a magnet 55. The limiting ring 54 is fixedly connected to the surface of the limiting pin 52, and the magnet 55 is fixedly connected to the interior of the limiting pin 52.
[0046] The magnet 55 is fixedly connected to the top and bottom of the inner wall of the limiting groove 51.
[0047] After the limiting ring 54 moves up or down and moves to the appropriate position, the two magnets 55 attract each other and limit the limiting pin 52.
[0048] The working principle of the heating unit with improved reliability provided by this utility model is as follows:
[0049] In use, after the fixing pin 43 is inserted into the fixing hole 45, the limiting pin 52 is moved downward, thereby driving the limiting ring 54 to move downward inside the limiting groove 51. When the limiting ring 54 moves downward to the appropriate position, the limiting pin 52 is inserted into the limiting hole 53, thus limiting the fixing pin 43. At the same time, the magnet 55 inside the limiting ring 54 and the magnet 55 at the bottom of the limiting groove 51 attract each other, thus limiting the limiting pin 52.
[0050] Compared with related technologies, the heating unit with improved reliability provided by this utility model has the following beneficial effects:
[0051] This utility model provides a heating unit with improved reliability. The fixed pin 43 is limited by the limiting device 5, thereby increasing the stability of the fixed pin 43 when it is limited.
[0052] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
