Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to an automatic regulating valve for a coke oven gas compressor. Background Technology

[0002] In the modern coal chemical industry, methanol production is a crucial link, and the stability and operational efficiency of its process system directly impact the company's economic benefits and safety levels. The coke oven gas compressor, as the core equipment in the methanol plant's purification workshop, undertakes the critical tasks of gas compression and transportation, while the conversion valve is a core component ensuring smooth process flow and regulating system load. Previously, most companies in the industry used traditional manual valves for operation, which revealed significant drawbacks when facing large load increases or decreases or sudden abnormal operating conditions. Manual valves are large and have complex operating procedures, resulting in lengthy time for operators during equipment switching and start-up / shutdown processes, severely restricting production adjustment speed. This not only wastes coke oven gas resources and reduces methanol production but also extends the start-up time of subsequent processes such as synthesis and PSA hydrogen extraction, affecting the coordinated operation of the entire industrial chain. To address these issues, by replacing all manual valves at the inlet and outlet of the coke oven gas compressor, the vent valve, and the cross-line valve of the conversion steam drum feedwater heater with automatic regulating valves, central control regulation of valves related to compressor start-up / shutdown and shutdown was successfully achieved. After the modification, equipment reliability was significantly improved. Existing valve and pipeline connections mostly use flanges and multiple sets of bolts. However, in the coal chemical production process, equipment is under complex conditions of high pressure, vibration, and frequent impact from the medium for a long time. In addition, the frequency of valve adjustment increases after automation upgrades, causing the stress state at the flange connection to change constantly. Under this environment, even if the initial installation meets the specifications, the bolts are prone to loosening after long-term use, which can easily lead to loosening of the valve and pipeline connection, causing the leakage of flammable, toxic, and harmful gases. This not only pollutes the production environment but also brings serious safety hazards and may cause major safety accidents such as fires and explosions. Utility Model Content

[0003] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that after long-term use, the bolts are easy to loosen, which can easily lead to loosening of the connection between the valve and the pipeline, causing the leakage of flammable, toxic and harmful gases. This not only pollutes the production environment, but also brings serious safety hazards and may cause major safety accidents such as fires and explosions. To this end, we propose an automatic regulating valve for coke oven gas compressor.

[0004] To achieve the above objectives, this application adopts the following technical solution: an automatic regulating valve for a coke oven gas compressor, comprising a valve body and an actuator disposed at the upper end of the valve body, wherein both ends of the valve body are connected to mounting flanges, and the inner wall of the mounting flange is fixedly connected to a pre-installed pipe port; The inner wall of the pre-installed pipe port is provided with a connecting pipe, and the upper wall of the pre-installed pipe port is equipped with a reinforcing component. The reinforcing component includes a control block rotatably connected to the upper wall of the pre-installed pipe port and an movable channel opened in the upper wall of the pre-installed pipe port. The lower end of the control block is fixedly connected with a threaded rod, and the outer wall of the threaded rod is threadedly connected with a reinforcing block.

[0005] Furthermore, both sides of the reinforcing block are fixedly connected to a slider body, and both sides of the inner wall of the movable channel are provided with a sliding groove body, and the slider body is slidably connected to the inner wall of the sliding groove body.

[0006] Furthermore, when the slider body fits into the bottom of the cavity of the slide groove body, the lower wall of the reinforcing block protrudes out of the movable channel.

[0007] Furthermore, the upper wall of the connecting pipe is provided with a reinforcement port that matches the reinforcement block. An adsorption magnetic block A is fixedly connected to the outer wall of the reinforcement block, and an adsorption magnetic block B is arranged around the inner wall of the reinforcement port. The adsorption magnetic block A and the adsorption magnetic block B are attracted to each other by opposite poles.

[0008] Furthermore, a sealing ring is fitted on the outer wall of the reinforcing block, and the sealing ring is located at the lower end of the adsorption magnetic block A.

[0009] Furthermore, the sealing ring is a component made of rubber, and the interior of the sealing ring has a hollow structure. The outer diameter of the sealing ring is larger than the inner diameter of the reinforcement opening.

[0010] The technical effects and advantages of this utility model are as follows: In this invention, when reinforcing the connection, rotating the control block drives the threaded rod to rotate. Because the reinforcing block is threadedly connected to the threaded rod, and the slider body slides along the slide groove body to restrict its rotation, the reinforcing block moves axially along the threaded rod under the action of the thread. When the slider body fits against the bottom of the slide groove body cavity, the lower wall of the reinforcing block protrudes out of the active channel and inserts into the reinforcing port. By using the mechanical structure to lock, the relative displacement between the connected pipe and the pre-installed pipe port is restricted from a physical perspective, enhancing connection stability, relieving the load pressure on the bolts, reducing the risk of loosening, and solving the problem that after long-term use, bolts are prone to loosening, which can easily lead to loosening of the valve and pipe connection, causing the leakage of flammable, toxic and harmful gases, not only polluting the production environment, but also bringing serious safety hazards, and may cause major safety accidents such as fires and explosions.

[0013] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0014] Please see Figures 1 to 4 To address the issue that bolts tend to loosen after prolonged use, potentially leading to loose connections between valves and pipelines and causing leaks of flammable, toxic, and harmful gases. This not only pollutes the production environment but also poses serious safety hazards, possibly resulting in major accidents such as fires and explosions. The following preferred technical solutions are provided: An automatic regulating valve for a coke oven gas compressor includes a valve body 1 and an actuator 2 disposed on the upper end of the valve body 1. The actuator 2 is used to automatically control the opening degree of the valve body 1. Both ends of the valve body 1 are connected to mounting flanges 3. A pre-installed pipe port 4 is fixedly connected to the inner wall of the mounting flange 3. A connecting pipe 5 is provided on the inner wall of the pre-installed pipe port 4. A reinforcing component 6 is installed on the upper wall of the pre-installed pipe port 4. The reinforcing component 6 includes a control block 61 rotatably connected to the upper wall of the pre-installed pipe port 4 and a movable channel 62 opened on the upper wall of the pre-installed pipe port 4. A threaded rod 63 is fixedly connected to the lower end of the control block 61. A reinforcing block 64 is threadedly connected to the outer wall of rod 63. A slider body 65 is fixedly connected to both sides of the reinforcing block 64. A sliding groove body 66 is provided on both sides of the inner wall of the movable channel 62. The slider body 65 is slidably connected to the inner wall of the sliding groove body 66. When the slider body 65 is in contact with the bottom of the cavity of the sliding groove body 66, the lower wall of the reinforcing block 64 protrudes out of the movable channel 62. Rotating the control block 61 drives the threaded rod 63 to rotate. Because the reinforcing block 64 is threadedly connected to the threaded rod 63, and the slider body 65 slides along the sliding groove body 66 to restrict its rotation, the reinforcing block 64 moves axially along the threaded rod 63 under the action of the thread.

[0015] The upper wall of the connecting pipe 5 is provided with a reinforcement port 67 that matches the reinforcement block 64. An adsorption magnetic block A68 is fixedly connected to the outer wall of the reinforcement block 64. An adsorption magnetic block B69 is arranged around the inner wall of the reinforcement port 67. The adsorption magnetic blocks A68 and B69 are attracted by opposite poles. A sealing ring 610 is fitted on the outer wall of the reinforcement block 64. The sealing ring 610 is located at the lower end of the adsorption magnetic block A68. The sealing ring 610 is a component made of rubber and has a hollow structure inside. The outer diameter of the sealing ring 610 is larger than the inner diameter of the reinforcement port 67.

[0016] Specifically, during installation, the pre-installed pipe ports 4 at both ends of the valve body 1 are coaxially aligned with the connecting pipe 5, and initially fixed through the bolt holes of the mounting flange 3. At this time, the reinforcing block 64 is located within the movable channel 62, and its lower surface is flush with the inner wall of the pre-installed pipe port 4, which does not affect pipe insertion. When performing the reinforcement connection, the control block 61 is rotated, which drives the threaded rod 63 to rotate. Because the reinforcing block 64 is threadedly connected to the threaded rod 63, and the slider body 65 slides along the slide groove body 66 to restrict its rotation, under the action of the thread, the reinforcing block 64 moves axially along the threaded rod 63. When the slider body 64... 5. The bottom of the cavity of the sliding groove body 66 is fitted with the reinforcing block 64. The lower wall of the reinforcing block 64 protrudes from the movable channel 62 and is inserted into the reinforcing port 67. By using the mechanical structure to lock, the relative displacement between the connecting pipe 5 and the pre-installed pipe port 4 is physically restricted, which enhances the connection stability, relieves the load pressure on the bolts, and reduces the risk of loosening. This solves the problem that after long-term use, the bolts are easy to loosen, which can easily lead to loosening of the valve and pipe connection, causing the leakage of flammable, toxic and harmful gases. This not only pollutes the production environment, but also brings serious safety hazards and may cause major safety accidents such as fires and explosions.

[0017] During the insertion of the reinforcing block 64 into the reinforcing port 67, the magnetic blocks A68 and B69 attract each other due to the attraction of opposite poles, further positioning the reinforcing block 64 and improving the connection accuracy and stability. At the same time, the rubber sealing ring 610, with its hollow structure, can deform and fill the gap between the reinforcing block 64 and the reinforcing port 67 after being squeezed. By utilizing the elastic sealing properties of rubber and the pre-tightening force generated by magnetic attraction, the sealing effect of the connection is strengthened, preventing the leakage of flammable, toxic and harmful gases.

[0018] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
