[0002] In the piping systems of environmental protection equipment (such as waste gas treatment towers and sewage treatment pressure tanks), safety valves are key components ensuring the safe operation of the system. They need to automatically open and relieve pressure when the system pressure exceeds a set threshold to prevent damage to the equipment due to overpressure. Currently, most environmental protection safety valves have a single-position pressure regulation design, meaning that a single pressure threshold is set by rotating an adjusting bolt to change the spring compression.

[0003] When adjusting the pressure of existing environmentally friendly safety valves, it is necessary to repeatedly rotate the bolt to change the spring compression. This is not only cumbersome to operate, but also difficult for traditional structures to adapt quickly in working conditions where frequent switching of pressure thresholds is required, affecting the operating efficiency and safety of the equipment. Therefore, a multi-position adjustable environmentally friendly safety valve is needed to solve the above problems. Utility Model Content

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] like Figures 1-4 As shown, this utility model provides a technical solution: a multi-level adjustable environmentally friendly safety valve, including a discharge pipe 1, an inlet pipe 101 fixedly connected to the bottom end of the discharge pipe 1, an adjusting pipe 102 fixedly installed at the top end of the discharge pipe 1, a filter assembly 2 inside the discharge pipe 1, the filter assembly 2 including a mounting bracket 201, the mounting bracket 201 being threadedly connected to the inner side of the discharge pipe 1, a plurality of protrusions 202 fixedly connected to the inner side of the mounting bracket 201, a filter screen 203 fixedly connected to the inner side of the mounting bracket 201, and an adjusting assembly 3 inside the adjusting pipe 102. The top of 102 is equipped with a limiting component 4 for fixing the adjusting component 3. By cooperating with the adjusting component 3 and the limiting component 4, different pressure levels can be switched directly without repeatedly rotating the bolt. This solves the problems of cumbersome adjustment and difficulty in quickly adapting to frequent pressure switching conditions of traditional single-level safety valves, significantly improving operating efficiency and ensuring system operation safety. The filter component 2 can filter impurities in the medium, preventing impurities from entering the safety valve and affecting its sealing performance and adjustment accuracy, extending the service life of the safety valve and the entire pipeline system, and meeting the clean operation requirements of environmental protection equipment. As one implementation method in this embodiment, such as Figure 1 and Figure 3 As shown, the adjustment assembly 3 includes an adjustment rod 301, which is inserted into the top of the feed pipe 101. The bottom end of the adjustment rod 301 is provided with a spring seat, and the top end of the adjustment rod 301 is fixedly connected to a button 302. Several gear lines 304 are provided on the outer end of the adjustment rod 301, and each gear line 304 has a hole 305 on its side. The top end of the button 302 is provided with anti-slip texture 303. In practice, the gear lines 304 make it easy for personnel to observe the adjustment gear index, and the anti-slip texture 303 improves the protective performance of the button 302 and makes it convenient for personnel to press. As one implementation method in this embodiment, such as Figure 2 and Figure 4 As shown, the limiting component 4 includes a first upright plate 401 and a second upright plate 403. Both the first upright plate 401 and the second upright plate 403 are fixedly connected to the top of the adjusting tube 102. Two connecting plates 402 are fixedly connected between the side ends of the first upright plate 401 and the second upright plate 403. A pull head 404 is provided on the side end of the first upright plate 401. A fixing rod 406 is fixedly connected to the side end of the pull head 404. The fixing rod 406 is inserted into the side end of the first upright plate 401. A fixing plate 407 is fixedly connected to the side end of the fixing rod 406. An insertion rod 408 is fixedly connected to the side end of the fixing plate 407. The side end of the insertion rod 408 is inserted into the side end of the second upright plate 403. The fixing plate 407 is located between the side ends of the two connecting plates 402. A spring 409 is sleeved on the outer end of the fixing rod 406. One end of spring 409 is fixedly connected to the side end of vertical plate 401, and the other end of spring 409 is fixedly connected to the side end of fixed plate 407. The outer end of pull head 404 is fixedly connected to protrusion 405. The top end of adjusting tube 102 is provided with slide groove 103. The bottom end of fixed plate 407 is fixedly connected to slider 410, which is slidably connected in slide groove 103. Insert rod 408 is adapted to several insertion holes 305. In practice, first pull head 404 in limiting assembly 4 is pulled. Pull head 404 drives fixed rod 406 to move towards vertical plate 401. Spring 409 at the outer end of fixed rod 406 is compressed. Fixed plate 407 moves with fixed rod 406 and drives insert rod 408 to be pulled out from the side end of insertion hole 305, releasing the limitation on adjusting rod 301. At this time, the button 302 at the top of the adjusting rod 301 can be pressed or pulled. The anti-slip texture 303 at the top of the button 302 facilitates operation. The adjusting rod 301 moves along the inside of the adjusting tube 102. Observe the gear line 304 at the outer end of the adjusting rod 301 and adjust it to the gear corresponding to the required pressure. When the target insertion hole 305 on the adjusting rod 301 is aligned with the position of the insertion rod 408, release the pull head 404. The spring 409 returns to its elastic deformation, pushing the fixing plate 407 and the insertion rod 408 to reset. The insertion rod 408 is inserted into the corresponding insertion hole 305. At the same time, the slider 410 at the bottom of the fixing plate 407 slides along the slide groove 103 at the top of the adjusting tube 102 to ensure that the insertion rod 408 is accurately inserted, completing the pressure setting of this gear. This solves the problems of troublesome adjustment and difficulty in quickly adapting to frequent pressure switching conditions of traditional single-gear safety valves, significantly improving operating efficiency and ensuring the safety of system operation. Working principle: When adjusting the pressure, first pull the pull head 404 in the limiting component 4. The pull head 404 drives the fixed rod 406 to move towards the vertical plate 401. The spring 409 at the outer end of the fixed rod 406 is compressed. The fixed plate 407 moves with the fixed rod 406 and drives the insertion rod 408 to be pulled out from the side end of the insertion hole 305, releasing the limitation on the adjusting rod 301. At this time, the button 302 at the top of the adjusting rod 301 can be pressed or pulled. The anti-slip texture 303 at the top of the button 302 facilitates operation. The adjusting rod 301 moves along the inside of the adjusting tube 102. Observe the gear line 304 at the outer end of the adjusting rod 301 and adjust it to the gear corresponding to the required pressure. When the target insertion hole 305 on the adjusting rod 301 is aligned with the insertion rod 408, release the pull head 404. The spring 409 returns to its elastic deformation, pushing the fixing plate 407 and the insertion rod 408 to reset. The insertion rod 408 is inserted into the corresponding insertion hole 305. At the same time, the slider 410 at the bottom of the fixing plate 407 slides along the slide groove 103 at the top of the adjusting tube 102 to ensure that the insertion rod 408 is accurately inserted, completing the pressure setting of this gear. At this time, the spring seat at the bottom of the adjusting rod 301 fixes the compression of the internal spring, and the opening pressure threshold of the safety valve is determined accordingly. During the operation of the system, the medium enters from the feed pipe 101 and passes through the discharge pipe 1 The filter screen 203 of the internal filter assembly 2 filters and intercepts impurities, and the purified medium continues to flow. When the system pressure exceeds the currently set threshold, the medium pressure pushes the spring seat, and the safety valve opens to relieve pressure. After the pressure drops below the threshold, the spring resets and closes the safety valve, realizing system safety protection. By adjusting the gear line 304 and the socket 305 of the adjustment assembly 3 in conjunction with the plug rod 408 of the limit assembly 4, different pressure gears can be directly switched without repeatedly rotating the bolt. This solves the problems of cumbersome adjustment and difficulty in quickly adapting to frequent pressure switching conditions of traditional single-gear safety valves, significantly improving operating efficiency and ensuring system operation safety. The filter screen 203 of the filter assembly 2 can filter impurities in the medium, preventing impurities from entering the safety valve and affecting its sealing and adjustment accuracy, thus extending the service life of the safety valve and the entire pipeline system. The filter screen 203 can be disassembled by rotating the convex block 202, which meets the clean operation requirements of environmental protection equipment.
