Description

Technical Field

[0001] This utility model relates to the field of heating furnace regulation technology, specifically a heating furnace regulating valve mechanism. Background Technology

[0002] A heating furnace regulating valve is a key device used to precisely control the temperature, pressure, or flow rate inside a heating furnace. It ensures the stability and efficiency of the heating process by regulating the flow rate of the medium. It consists of a valve body, a valve core, and an actuator. Heating furnace regulating valves are widely used in industrial heating furnace systems. They not only enable precise control of temperature, pressure, and flow rate, but also play a role in safety protection and energy saving. They are an important component for realizing the automation and process optimization of heating systems.

[0003] Traditional heating furnace regulating valves adjust the flow rate of the medium by changing the valve core opening, thereby controlling the temperature, pressure, or flow rate inside the heating furnace. When the temperature or pressure inside the heating furnace changes, the valve core needs to be manually rotated to adjust the valve opening, thus changing the medium flow rate. The sensor transmits the signal to the control system, which, based on the deviation between the set value and the actual value, sends a command to the actuator of the regulating valve. The actuator drives the valve core to move, adjusting the valve opening, thereby changing the medium flow rate and restoring the temperature or pressure to the set value. However, the above-mentioned device is not stable enough in terms of valve core control during use, resulting in fluctuations in the medium flow rate, causing temperature fluctuations in the heating furnace, affecting product quality and process stability. Unstable medium flow rate can also cause pressure fluctuations, increasing the risk of equipment failure. Furthermore, operators need to frequently adjust and monitor the position of the valve core, increasing the difficulty and complexity of operation. In addition, unstable valve core control can lead to operator errors during valve opening adjustments, further affecting control accuracy. Utility Model Content

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.

[0028] Please refer to Figure 1 , Figure 2 and Figure 3 A heating furnace regulating valve mechanism, comprising:

[0029] A connecting channel 1 is provided, with connecting plates 4 installed on both sides. A valve 6 is installed inside the connecting channel 1, and a valve core 5 is movably installed inside the valve 6. The valve 6 has multiple evenly distributed flow ports. The valve core 5 cooperates with the multiple flow ports. A sealing ring 7 is installed at the connection between the valve 6 and the valve core 5. A sealing block is fixed at the bottom of the valve core 5. A receiving groove for the sealing block to be inserted is opened at the bottom of the connecting channel 1. An inclined groove that communicates with each other is opened on both sides of the receiving groove. A sensor 8 is installed on one side of the connecting channel 1.

[0030] Please refer to Figure 2 - Figure 5Adjustment mechanism 2, located at the top of connection channel 1, is used to precisely position valve core 5. Adjustment mechanism 2 includes a support assembly, a plug-in assembly, a drive assembly, and a positioning assembly. The support assembly is located at the top of connection channel 1 and supports valve core 5. The plug-in assembly is located on one side of the support assembly and plugs valve core 5 into it. The drive assembly is located at the top of connection channel 1 and drives the plug-in assembly to move horizontally. The positioning assembly is located at the top of the support assembly and positions the plug-in assembly. The support assembly includes two support seats 25 fixed to the top of connection channel 1. Multiple evenly distributed rollers 210 are installed on opposite sides of the two support seats 25, and multiple rotating grooves for the rollers 210 to rotate are opened on opposite sides of the support seats 25. The rollers 210 cooperate with the outer wall of valve core 5. The plug-in assembly includes a plug plate 211 inserted into one of the support seats 25 and two plug rods. A control mechanism is installed on one side of the two plug rods and the plug plate 211. The valve core 5 has multiple evenly distributed insertion holes inside, and the insertion plate 211 cooperates with the insertion holes. The drive assembly includes a fixed groove on the top of the connecting channel 1 and a threaded rod 22 installed inside the fixed groove. A threaded plate 23 is screwed onto the outer wall of the threaded rod 22. The top of the threaded plate 23 is fixed to the bottom of the control plate 24. A drive motor 21 is fixed on the top of the connecting channel 1. The output end of the drive motor 21 is connected to the threaded rod 22. The positioning assembly includes a positioning seat 26 fixed on the top of one of the support seats 25. A cavity is opened inside the positioning seat 26. A movable sleeve is provided inside the cavity. Movable rods and positioning rods 29 are connected to the upper and lower ends of the movable sleeve. A slot for the positioning rod 29 to be inserted is opened on the top of the insertion plate 211. The movable rod extends to the top of the positioning seat 26 and is fixed with a control sleeve 27. A spring 28 is directly connected to the cavity and is sleeved on the outer wall of the movable rod.

[0031] The drive motor 21 drives the threaded rod 22 to rotate, which in turn causes the threaded plate 23 to move on its outer wall. This movement of the threaded plate 23 then moves the control plate 24, which in turn moves the two insert rods and the insert plate 211 synchronously. The movement of the insert plate 211 separates it from the valve core 5 and simultaneously moves the slot. When the slot reaches the position corresponding to the positioning rod 29, the spring force of the spring 28 causes the moving sleeve to move downwards. This downward movement of the moving sleeve causes the positioning rod 29 to move downwards. The valve core 5 is then pulled to make it insert into the slot, and then the valve core 5 is moved inside the valve 6. The multiple rollers 210 make the valve core 5 more stable and smooth during the up and down movement, and it is not easy to tilt or jam. When the valve core 5 moves to the required position, the control sleeve 27 is pulled to drive the movable rod to move upward. The upward movement of the movable rod causes the movable sleeve to drive the spring 28 to contract. The contraction of the spring 28 causes the positioning rod 29 to separate from the slot. Then, the drive motor 21 causes the insert plate 211 to insert into the valve core 5, thereby achieving precise positioning of the valve core 5.

[0032] Please also refer to... Figure 2 and Figure 6 A disassembly mechanism 3 is provided between the connecting channel 1 and the valve 6 to facilitate the disassembly of the valve 6. The disassembly mechanism 3 includes a disassembly seat 31 fixed on both sides of the valve 6. Disassembly slots for the disassembly seat 31 to move are provided on both sides of the connecting channel 1. Bolts 32 are screwed between the disassembly seat 31 and the connecting channel 1. Control slots 33 are provided on both sides of the valve 6. The control slots 33 are located on the top of the disassembly seat 31.

[0033] When valve 6 needs to be disassembled, the screw bolt 32 is turned to separate it from the disassembly seat 31. After the bolt 32 and the disassembly seat 31 are separated, the control groove 33 is pulled to move the disassembly seat 31 within the disassembly groove. The movement of the disassembly seat 31 causes the valve 6 to move synchronously until it is separated from the connecting channel 1, thereby completing the disassembly of valve 6 and making it convenient for users to clean and replace valve 6.
