Description

Technical Field:

[0001] The present invention relates to the technical field of desuperheating and pressure reducing devices, and particularly to a regulating valve for a desuperheating and pressure reducing device with an efficient activated carbon filtering structure. Background Art:

[0002] In modern industrial production, especially in application scenarios involving boiler steam, desuperheating and pressure reducing devices play a crucial role. The steam generated by boilers usually has high temperature and pressure, while the actual production process often requires steam with different parameters, which necessitates the desuperheating and pressure reducing device to precisely regulate the steam. As the core component of the desuperheating and pressure reducing device, the performance of the regulating valve directly affects the operation stability of the entire system and the steam quality.

[0003] Traditional regulating valves for desuperheating and pressure reducing devices have many drawbacks. In terms of filtration, most regulating valves are only equipped with simple filtering structures, making it difficult to effectively remove impurities and harmful gases in the steam. Boiler steam often contains various particulate impurities, such as rust and scale particles generated during boiler operation, as well as possible harmful gas components. If these impurities and gases enter the subsequent production processes with the steam, they may cause wear and corrosion to the production equipment, affect the normal service life of the equipment, and may also reduce the product quality. In some processes with extremely high requirements for steam quality, it may even lead to unqualified products.

[0004] In terms of spool regulation, traditional regulating valves mostly adopt a single spool structure, with limited regulation accuracy and difficulty in meeting the precise control requirements for steam flow and pressure under complex working conditions. For different production stages, the range of changes in the required steam flow and pressure is relatively large, and a single spool cannot flexibly and precisely achieve multi-stage regulation, resulting in large fluctuations in steam parameters and inability to stably supply steam meeting production requirements. Moreover, traditional spool regulating mechanisms often have complex structures, making maintenance and repair difficult, increasing the enterprise's operating costs and equipment downtime.

[0005] In addition, the filtering mechanism and the spool regulating mechanism of traditional regulating valves are independent of each other and do not form a collaborative working mechanism. This makes it impossible to effectively maintain the pressure difference stability on both sides of the filtering mechanism during the process of regulating steam flow and pressure, resulting in unstable filtering effects and shortened service life of the filtering components. Frequent replacement of the filtering components further increases production costs and maintenance workload. In view of these problems existing in traditional regulating valves for desuperheating and pressure reducing devices, it is of great practical significance to develop a new type of regulating valve with an efficient filtering structure and capable of precisely regulating steam flow and pressure. Summary of the Invention:

[0006] The object of the present invention is to provide a control valve for a temperature-reducing and pressure-reducing device with an efficient activated carbon filtration structure to solve the problems that the traditional control valve has poor filtration effect, the regulating accuracy of the traditional single-valve core structure control valve is limited, the filtration mechanism and the valve core regulating mechanism of the traditional control valve are independent of each other, and the pressure difference on both sides of the filtration mechanism cannot be maintained stable.

A clamping hole 514 is formed on the right front side of the outer frame body II 511.

[0041] The usage state of the present invention is as follows: The present invention has a reasonable and simple structure, low production cost, and is easy to install. When in use, first start the first motor 331 (servo motor or stepping motor). The output shaft drives the transmission shaft 332 to rotate in the transmission box 333. The rotation of the transmission shaft 332 drives the first driving gear 334, the second driving gear 337, and the third driving gear 3310 fixedly connected thereto to rotate synchronously. The first driving gear 334 drives the first driven gear 335 meshing therewith to rotate. The rotation of the first driven gear 335 causes the first screw 336 to rotate at the upper center of the valve core guide groove 31. Since the lower side of the first screw 336 is connected to the threaded hole provided on the upper side of the first valve core 32, the rotation of the first screw 336 drives the first valve core 32 to perform a vertical linear motion in the valve core guide groove 31. Similarly, the second driving gear 337 drives the second driven gear 338 to rotate, driving the second screw 339 to rotate, and further causing the second valve core 35 to perform a vertical linear motion in the second valve core guide groove 34;The driving gear three 3310 drives the driven gear three 3311 to rotate, driving the driving screw three 3212 to rotate, causing the valve core three 37 to perform a vertical linear motion within the valve core guide groove three 36. Through the control of the motor one 331, synchronous adjustment of the valve core one 32, valve core two 35, and valve core three 37 can be achieved, thereby controlling the flow rate and pressure of steam within the valve chamber passage 2. Here, the steam enters from the left side of the valve chamber passage 2. First, the steam passes through the coarse filtration mechanism 4, and then the steam passes through the coarse filtration component 42 within the valve chamber passage 2. The perforated plate one 422 within the outer frame body one 421 of the coarse filtration component 42 blocks larger particle impurities, and the coarse activated carbon filter material 423 adsorbs some smaller particle impurities and some harmful gases, etc. When the coarse filtration component 42 is blocked after a long time of filtration, the pressure on its left side is much greater than that on the right side, so that the steam on the left side of the coarse filtration component 42 enters the piston chamber 434 to push the piston 436 to move leftward. The leftward movement of the piston 436 causes the locking rod 432 to disengage from the locking hole 424, and then under the action of the spring one 45, it pushes the new coarse filtration component 42 to move backward into the valve chamber passage 2. As the coarse filtration component 42 moves backward into the valve chamber passage 2, the pressure difference between its left and right sides will decrease, enabling the locking rod 432 to be inserted into the locking hole 424 of the new coarse filtration component 42 to complete the fixation, thus meeting the need for automatic replacement of the coarse filtration component 42. When the steam is coarsely filtered, it will enter the fine filtration component 51 within the fine filtration mechanism 5 for fine filtration. Here, the perforated plate two 512 within the outer frame body two 511 of the fine filtration component 51 further blocks tiny particle impurities, and the fine activated carbon filter material 513 performs a more refined adsorption filtration on the steam, removing residual tiny impurities and harmful gases, etc., so that the steam is purified more thoroughly. When the fine filtration component 51 filters for a period of time, the pull rod two 56 is pulled to make the slider 55 drive the clamping rod 54 away from the clamping hole 514, and then under the action of the spring four 53, the new fine filtration component 51 enters the valve chamber passage 2. At the same time, the pull rod two 56 is released to make the clamping rod 54 be inserted into the corresponding clamping hole 514 to complete the fixation. In addition, both the coarse filtration mechanism 4 and the fine filtration mechanism 5 are located inside the multi-position valve core mechanism 3, thereby ensuring the stability of the pressure difference on both sides of the coarse filtration mechanism 4 and the fine filtration mechanism 5 after adjustment, and also improving the service life of the coarse filtration mechanism 4 and the fine filtration mechanism 5. During the whole process, the multi-position valve core mechanism 3 adjusts the flow rate and pressure of the steam according to actual needs, and the coarse filtration mechanism 4 and the fine filtration mechanism 5 work together to filter the steam efficiently, ensuring that the outflowing steam meets the usage requirements of the desuperheating and pressure-reducing device.;
