Description

Technical Field

[0001] The invention relates to the technical field of flanges, in particular to a flange which is convenient for connection and installation. Background Art

[0002] In the petroleum, chemical, natural gas and other industries, various fluid media need to be transported through pipelines. Flange connections provide a reliable way to connect pipelines to ensure safe and efficient transportation of media in the pipeline system. Pipes connected by flanges can withstand high temperatures and certain pressures to prevent media leakage.

[0003] According to the Chinese patent publication number CN222046991, the patent provides a rectangular flange reinforced connection structure, including a silicone rubber cone ring fixedly connected to one side of the rectangular flange body, a sleeve assembly fixedly connected to one side of the silicone rubber cone ring, and a buffer expansion assembly fixedly connected to the outside of the silicone rubber sleeve. The device can prevent pipeline deformation caused by thermal expansion and contraction, and at the same time has a certain degree of flexibility and bendability, reducing the risk of pipeline leakage caused by pipeline vibration due to excessive flow rate.

[0004] When the flange expands and contracts due to heat and cold, the traditional technology often uses the pipeline thermal compensation method. The refrigeration and heating equipment directly intervenes the flange from the outside to control the temperature. The intervention efficiency of pipeline thermal compensation is low, and it is difficult to heat the flange evenly from the inside to the outside. The cost of direct intervention using refrigeration and heating equipment is high, and human intervention is required, which is not convenient enough. At the same time, the sealing gasket between the flanges will be excessively squeezed and contracted due to thermal expansion and contraction, causing the sealing gasket to exceed its elastic deformation range and lose some elastic recovery ability, thereby affecting the sealing effect. Therefore, a flange that is easy to connect and install is proposed to solve the above problems. Summary of the invention

[0018] 3. The flange, which is easy to connect and install, adopts the method of sealing ring deformation compensation. When the sealing ring expands, it squeezes the inner tank for buffering. When it shrinks, the gas in the inner tank expands to compensate for the reduction of the sealing ring, so as to avoid excessive squeezing of the sealing ring and the disc body or the generation of fitting gaps, extend the service life of the sealing ring, ensure the sealing of the pipe connection, and the rubber ring assists in sealing and waterproofing.

[0020] 5. The flange, which is easy to connect and install, has improved buffering and protection functions. The inner tank buffers vibration and water pressure. After the inner tank is inflated, it is squeezed and deformed by the sealing ring, which can buffer the water flow pressure and pipe wall vibration, reduce the impact on the flange and pipe fittings, and protect the pipeline system.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1-8 The present invention provides a technical solution: a flange that is easy to connect and install, including a disk body 1, which is the main structure of the flange.

The cold and hot compensation part 3 of this case includes a semiconductor cooling sheet 35 and a microcontroller 37. MCU-Arduino is used to generate control signals. TEC can realize the switching between cooling and heating functions. When cooling is required, one side of it absorbs heat and the other side releases heat. When the current direction is changed for heating, the side that originally absorbs heat becomes heat release, and the side that originally releases heat becomes heat absorption. The end surface of the semiconductor cooling plate 35 is fixedly connected with a guide column 36. The guide column 36 is made of copper material and is used to match and connect with the spiral copper wire 25 for heat conduction. The end of the spiral copper wire 25 extends to the disk body 1 through the notch of the spiral groove 24. The outer part of the spiral copper wire 25 is fixedly connected to the end of the guide column 36, and the pitch change effect is automatically achieved through the characteristics of thermal expansion and contraction. The pitch change part 4 in this case includes a positioning ring 41, which is slidably connected to the inner wall of the second installation groove 22, and the inner wall of the sliding hole 23 is slidably connected to a sliding rod 43.

The front of the positioning ring 41 is fixedly connected There is a rubber ring 42, which is attached to the inner wall of the second mounting groove 22. The rubber ring 42 can drive the slide bar 43 to slide under the deformation of thermal expansion and contraction, thereby causing the slide bar 43 to move and change its pitch. The control unit 6 in this case includes a distance sensor 64, model dt35-b15251 laser sensor. The distance sensor 64 is aligned with the slide hole 23. The distance sensor 64 is used to monitor the sliding pitch of the slide bar 43, thereby sending an induction signal to feedback to the microcontroller 37, and then deciding to switch the working mode of the semiconductor cooling plate 35.

[0027] In order to evenly heat and dissipate heat from the inside to the outside of the flange, the heat compensation part 3 of the present case also includes a frame 31, and mounting feet 32 ​​are symmetrically installed on both sides of the top of the frame 31. The two mounting feet 32 ​​are installed on the outer wall of the disk body 1. Threading holes 33 are opened on both sides of the frame 31, and a vent hole 34 is opened in the middle of the top of the frame 31. The semiconductor cooling sheet 35 is installed on the inner wall of the frame 31, and the end of the guide column 36 passes through the vent hole 34 upward. The vent hole 34 is conducive to the heat dissipation of the semiconductor cooling sheet 35. The microcontroller 37 is installed at the bottom of the outer wall of the frame 31, and the slide rod 43 and There are six springs 44, six slide bars 43 are fixed on the back of the positioning ring 41, six springs 44 are arranged on the back of the positioning ring 41, and the six slide bars 43 are respectively slidably connected to the inner walls of the six slide holes 23. The front of the outer wall of the frame 31 is flush with the front of the disk body 1, and the front of the rubber ring 42 extends to the outside of the mounting groove 22. One side of the rubber ring 42 is initially located outside the disk body 1 to provide deformation space for thermal expansion and contraction. The rubber ring 42 is placed under contraction deformation to form a gap, and the microcontroller 37 is electrically connected to the semiconductor cooling sheet 35.

[0028] It is worth noting that in order to adapt to different types of pipe sizes, the connecting part 5 in this case includes a pipe sleeve 51. The inner diameter of the pipe sleeve 51 is selected to adapt to the outer diameters of different pipes. The pipe sleeve 51 is inserted into the inner wall of the disk body 1 and is tightly attached to the inner wall of the sealing ring 7. The rear end pipe mouth of the pipe sleeve 51 is fixedly connected with a positioning disk 52. Six insertion holes 53 are arranged around the positioning disk 52. The back side of the disk body 1 is arranged around the six insertion holes 53. The inner wall of each insertion hole 53 is threadedly connected to the inner wall of the corresponding threaded groove 54 with a bolt 55. The array distribution of the six bolts 55 can enable the connecting part 5 to be stably installed on the disk body 1.

[0029] In order to further install the distance sensor 64 according to the use requirements, the control part 6 in this case also includes a ring sleeve 61. The rear end of the tube sleeve 51 extends to the outside of the back side of the disk body 1. The ring sleeve 61 is fixedly sleeved on the outer wall of the extended end of the tube sleeve 51.

The distance sensor 64 is electrically connected to the microcontroller 37. The distance sensor 64 can be installed on any one of the clips 63 to align with the corresponding sliding hole 23.

[0030] It is worth noting that the sealing ring 7 is fixedly connected to the inner wall of the mounting groove 21, and the sealing ring 7 is used to seal the joint of the two pipe fittings after the flange connection. The deformation compensation part 8 in this case includes an inner liner 81, and the inner liner 81 can store gas and expand. The outer wall of the inner liner 81 is fixedly connected to the inner wall of the mounting groove 21, and the inner liner 81 is located between the sealing ring 7 and the mounting groove 21. The outer wall of the inner ring of the inner liner 81 is in contact with the outer wall of the sealing ring 7, and the outer wall of the inner liner 81 is fixedly connected to the inflation tube 82, and the inflation tube 82 is in contact with the inflation tube 82. The inner wall of the liner 81 is connected, and the inner liner 81 is inflated by an air filling tube 82. The air filling tube 82 is fixedly passed through the inner wall of the mounting groove 21 and is bent to extend to the outside of the disk body 1. The extended end of the air filling tube 82 is threadedly connected with a sealing cap 83. The sealing cap 83 can effectively reduce the gas loss rate. The outer wall of the liner 81, the outer wall of the sealing ring 7, the outer wall of the spiral copper wire 25 and the front end of the pipe sleeve 51 are all aligned with the front side of the disk body 1. The aligned setting can ensure a tight fit between the two disk bodies 1 in actual applications.

[0031] Working principle: In actual use, the device of this case includes at least two devices for combined use. The pipe sleeves 51 on the two disk bodies 1 are respectively sleeved on the ports of the two pipe fittings, and the two pipe fittings are made to fit together. The two disk bodies 1 fit each other and are conventionally installed and fixed. The extended end position of the pipe sleeve 51 is used to reserve sliding space for the distance sensor 64 and the slide rod 43 to ensure the normal operation of the monitoring work. The two pipe sleeves 51 and the two sealing rings 7 are abutted against each other to ensure the sealing of the pipe connection. A certain amount of gas is flushed into the inner liner 81 through the inflation tube 82 to expand it, and it is sealed with the sealing cap 83. The expanded inner liner 81 is squeezed by the sealing ring 7 to deform, and at the same time can buffer the problems of water flow pressure and pipe wall vibration.

[0032] In actual applications, the design of the inner liner 81 does not only consider the factor of thermal expansion coefficient. The inner liner 81 will be pre-inflated to a certain pressure state before installation. The material of the inner liner 81 can be a rubber material with good elasticity and temperature resistance, and its material has certain elasticity and pressure resistance. When the sealing ring 7 expands due to heat, the inner liner 81 will expand due to the increase in temperature, but due to its pre-set pressure and material properties, it can buffer and disperse part of the expansion force of the sealing ring 7 instead of intensifying the extrusion of the sealing ring 7. It can maintain stable mechanical properties within a certain temperature range. When the sealing ring 7 is thermally expanded and extruded, it will absorb part of the pressure through its own elastic deformation to avoid excessive extrusion and deformation of the sealing ring 7.

[0033] When the environment or operating temperature changes, the sealing ring 7 will squeeze the inner liner 81 for buffering when it expands due to heat, thereby avoiding the risk of excessive extrusion caused by direct contact with the disk body 1. When the sealing ring 7 shrinks due to cold, the inner liner 81 will compensate for the reduction of the sealing ring 7 through the expansion deformation of the internal gas, thereby avoiding the hidden danger of a fitting gap in the sealing ring 7 and extending the service life of the sealing ring.

[0034] When the sealing ring 7 shrinks, the inner liner 81 will expand outward under the action of pressure due to the pre-filled gas. Although the gas has the characteristic of shrinking, under actual working conditions, the gas pressure inside the inner liner 81 is sufficient to support it to compensate for the shrinkage of the sealing ring 7 to a certain extent. This is because the inner liner 81 fits tightly against the sealing ring 7, and the structural design of the inner liner 81 prevents it from shrinking significantly instantly when shrinking. In a low temperature environment, its rubber material has a certain elastic retention ability, and combined with the internal gas pressure, it can effectively fill the gap caused by the shrinkage of the sealing ring 7 and maintain the sealing effect.

[0035] After the two disk bodies 1 are spliced ​​together, the protruding rubber rings 42 will squeeze each other and slide into the inner walls of their respective mounting grooves 22, thereby squeezing the spring 44 and driving the end of the slide rod 43 to slide along the slide hole 23, prompting the end of the slide rod 43 to align with the back of the respective disk bodies 1. At this time, the distance sensor 64 is turned on, and the distance between it and the slide rod 43 remains unchanged and is set to the initial distance. The wiring of the semiconductor refrigeration plate 35 can extend to the outside through the threading hole 33 to ensure that the semiconductor refrigeration plate 35 is correctly powered on. The space formed by the splicing of the two frames 31 can prompt the two guide pillars 36 to approach each other, avoid excessive contact between the guide pillars 36 and the outside, and enhance the heat conduction efficiency.

[0036] When the rubber ring 42 expands and deforms due to thermal expansion, the two rubber rings 42 squeeze each other and push their respective sliding rods 43. The distance sensor 64 detects the reduction in distance and prompts the microcontroller 37 to turn on the cooling mode of the semiconductor cooling plate 35 through a feedback signal, thereby quickly absorbing heat through the guide column 36 and quickly dissipating the temperature of the disk body 1 from the spiral copper wire 25 for automatic temperature regulation, replacing manual management, reducing the investment cost of labor and equipment, and the heat dissipation efficiency is uniform and efficient from the inside to the outside.

[0037] When the rubber ring 42 shrinks due to cold deformation, the size of the two rubber rings 42 is reduced, and the elastic force of the spring 44 adaptively compensates to push each rubber ring 42, so that the two rubber rings 42 can always maintain a fit state. At this time, the distance sensor 64 detects the increase in the distance from the slide rod 43, and prompts the microcontroller 37 to switch the heating mode of the semiconductor refrigeration plate 35 through the feedback signal, which is transmitted to the spiral copper wire 25 through the guide column 36, so that the disk body 1 is quickly heated from the inside to the outside, thereby improving the flange's ability to adapt to the environment and working temperature, so that the flange is always at a suitable temperature to work, thereby extending the service life of the flange.

[0038] The tight fit between the two rubber rings 42 can further prevent water leakage in the pipeline, and can further block the water leaking from the sealing ring 7, thereby buying time for personnel to inspect and troubleshoot, thereby improving the safety of flange use.
