Description

Technical Field

[0001] This utility model relates to the field of pipeline technology, and in particular to a raw material air intake balancing device. Background Technology

[0002] In industrial gas production or combustion systems, the raw material air intake is the initial stage of the system, and its design and treatment directly affect the efficiency of subsequent processes and product quality.

[0003] During the pipeline transportation of raw air, the large size and high pressure of the air inlet pipe cause inconsistent pressures before and after the inlet valve, resulting in a large pressure difference. This creates air damping on both sides of the valve, hindering its opening and making it difficult to open. Furthermore, it causes large fluctuations in the raw air inlet pressure, which can easily lead to production accidents such as pump stoppage in the precooling system, molecular sieve impact, and water carryover.

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.

[0018] This utility model provides, for example Figure 1-4 The illustrated raw material air intake balancing device includes an intake valve 1, an intake pipe 2, a balancing mechanism 3, and an indicating mechanism 4. The intake valve 1 is located at one end of two intake pipes 2 connected together and is used to control the opening and closing of the raw material intake pipe. The intake pipes 2 are fixedly installed at both ends of the intake valve 1. The balancing mechanism 3 is located between the intake pipes 2 and is used to adjust the air pressure at both ends of the intake valve 1, reduce the air pressure difference on both sides of the intake valve 1, reduce air pressure resistance, and facilitate the opening of the intake valve 1. The indicating mechanism 4 is located on the balancing mechanism 3 and is used to observe the change in air pressure on the balancing mechanism 3 and display the pressure difference on both sides of the intake valve 1.

[0019] The balancing mechanism 3 includes a balancing valve 31, connecting pipes 32, a flange 33, and fastening bolts 34. The balancing valve 31 is located on one side of the inlet valve 1. The balancing valve 31 is used to regulate and stabilize flow rate, pressure, or direction in a fluid system, adjusting the pressure difference between the inlet pipes 2 to ensure pressure balance on both sides of the inlet valve 1. Connecting pipes 32 are located at both ends of the balancing valve 31. One end of the connecting pipe 32 is fixedly connected to the inlet pipe 2, and the connecting pipe 32 communicates with the inner cavity of the inlet pipe 2. The connecting pipes 32 are respectively located at both ends of the inlet valve 1. The two ends of the balancing valve 31 are connected to the two inlet pipes 2 respectively through the two connecting pipes 32, thus connecting the balancing valve 31 to the inlet pipes 2. The flange 33... One end of the balance valve 31 and the connecting pipe 32 are fixedly connected to the other end of the balance valve 31 and the connecting pipe 32 respectively. The flange 33 is set between the balance valve 31 and the connecting pipe 32. The fastening bolt 34 is inserted between the flange 33 and the fastening bolt 34. The fastening bolt 34 is fixed to the flange 33 by cooperating with the nut. One end of the connecting pipe 32 is fixedly connected to one end of the balance valve 31 through the cooperation of the flange 33 and the fastening bolt 34. By opening the balance valve 31, the balance valve 31 is connected to the air intake pipes 2 on both sides of the air intake valve 1 through the connecting pipe 32, so that the gas in the air intake pipes 2 on both sides enters the small-diameter connecting pipe 32. The gas on both sides is regulated by the balance valve 31 to reduce the pressure difference on both sides of the air intake valve 1, so as to facilitate the opening of the air intake valve 1.

[0020] The indicating mechanism 4 includes a fixed tube 41, a piston block 42, a protective membrane 43, a fixed seat 44, a solenoid valve 45, a connector 46, a threaded sleeve 47, and an indicating liquid 48. The fixed tube 41 is disposed between the connecting tubes 32 and is U-shaped. The fixed tube 41 is used to connect with the connecting tubes 32 and to install the piston block 42 and the protective membrane 43. The piston block 42 is slidably inserted into both ends of the inner cavity of the fixed tube 41. The piston block 42 is made of rubber material. When gas in the connecting tube 32 enters the fixed tube 41, the pressure generated by the gas pushes the piston block 42 to move within the inner cavity of one end of the fixed tube 41. The protective membrane... A protective membrane 43 is disposed between piston blocks 42 and is located within the inner cavity of the fixed tube 41. The inner wall of the protective membrane 43 is hollow to accommodate the indicating liquid 48. The indicating liquid 48 is filled within the protective membrane 43, and is positioned between the two piston blocks 42 through the protective membrane 43, causing the two piston blocks 42 to move together. When both ends of the fixed tube 41 are connected to two connecting tubes 32, gas from the two connecting tubes 32 enters both ends of the fixed tube 41. Utilizing the pressure difference between the two connecting tubes 32, the two piston blocks 42 and the protective membrane 43 move together, and the indicating liquid within the protective membrane 43... The position of indicator liquid 48 allows for a simple judgment of the pressure difference. When the indicator liquid 48 is stable in the middle of the fixed pipe 41, it indicates that the pressure between the two connecting pipes 32 has reached equilibrium, and consequently, the pressure on both sides of the indicator valve 1 has reached equilibrium. The fixed seat 44 is fixedly connected to one end of the connecting pipe 32. The fixed seat 44 is used to connect the fixed pipe 41 and the connecting pipe 32. The fixed seat 44 is used to connect the fixed pipe 41. The solenoid valve 45 is fixedly connected to both ends of the fixed pipe 41. The solenoid valve 45 controls the opening and closing of both ends of the fixed pipe 41. When the solenoid valve 45 is not open, both ends of the fixed pipe 41 are in a closed state. The connector 46 is fixedly connected to one end of the solenoid valve 45. The connector 46 is used to connect one end of the fixed base 44 and the fixed tube 41. The threaded sleeve 47 is slidably inserted into one end of the connector 46. The threaded sleeve 47 is threadedly connected to the fixed base 44. By rotating the threaded sleeve 47, the threaded sleeve 47 is threadedly connected to the fixed base 44. The threaded sleeve 47 moves on the fixed base 44, causing one end of the connector 46 to move together. The one end of the connector 46 is slidably inserted into the inner cavity of one end of the fixed base 44. As the threaded sleeve 47 is tightened, the threaded sleeve 47 causes one end of the connector 46 to be pressed and fixed to one end of the fixed base 44, ensuring a stable and sealed connection between the fixed base 44 and the connector 46.

[0021] The threaded sleeve 47 has an installation groove, which is movably engaged with one end of the connector 46. The inner wall of the installation groove presses against one end of the connector 46. A sealing ring 5 is inserted into one end of the connector 46. The sealing ring 5 is positioned between the fixed seat 44 and the connector 46. As the inner cavity of the threaded sleeve 47 expands, the fixed seat 44 and one end of the connector 46 are deformed by the pressure of the sealing ring 5. The sealing ring 5 ensures the airtightness between the fixed seat 44 and the connector 46.

[0022] The outer wall of the fixed seat 44 is provided with external threads for installing the threaded sleeve 47. The fixed seat 44 is connected to the inner cavity of the connecting pipe 32, allowing the gas in the connecting pipe 32 to enter the fixed pipe 41. The connecting pipe 32 is L-shaped. The outer wall of the piston block 42 is in contact with the inner wall of the fixed pipe 41. The elasticity of the piston block 42 ensures that the piston block 42 and the inner wall of the fixed pipe 41 are tightly fitted, guaranteeing the sealing between the piston block 42 and the fixed pipe 41. The indicating liquid 48 is a colored liquid, which facilitates the observation of the position of the indicating liquid 48.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
