[0002] A control valve is a device used in industrial automation process control to regulate process parameters such as flow rate, pressure, temperature, and liquid level. Based on control signals from the automation system, the valve automatically adjusts its opening to regulate these parameters.

[0003] Currently, most methods filter fine sand and rust from tap water pipes using a screening screen installed inside the pipe regulating valve, such as the pipe regulating valve disclosed in Chinese Patent Publication No. CN220134625U. However, when cleaning the filtered fine sand and rust, the tap water inside the pipe regulating valve is directly discharged through the cleaning port, which easily leads to waste of tap water. Summary of the Invention

[0004] The purpose of this utility model is to provide a pipeline regulating valve that solves the problem of water waste caused by the direct discharge of tap water through the cleaning port when cleaning the fine sand and rust accumulated inside the pipeline regulating valve.

[0005] The specific technical solution adopted by this utility model is as follows:

A conical cylinder is fixedly connected to the inner wall of the hollow partition plate. A first internally threaded cylinder is fixedly connected to the inner wall of the valve body. A threaded post is threadedly connected to the inner wall of the first internally threaded cylinder. A handle is fixedly connected to the top of the threaded post. A first sealing plug is fixedly connected to the bottom of the threaded post. The surface of the first sealing plug is in contact with the inner wall of the conical cylinder. An externally threaded cylinder is fixedly connected to the bottom of the hollow partition plate and the inner wall of the valve body. A first through hole is opened on the left side of the externally threaded cylinder. A filter assembly is fitted to the inner wall of the externally threaded cylinder. A cylinder is fitted to the surface of the filter assembly. A connecting post is fixedly connected to the surface of the cylinder and the bottom of the valve body. A positioning groove is opened at the bottom of the externally threaded cylinder. The inner wall of the positioning groove is in contact with the surface of the filter assembly. A nut is threadedly connected to the surface of the externally threaded cylinder. The upper surface of the nut is in contact with the bottom of the filter assembly.

[0007] The present invention is further configured such that the filter assembly includes a second internally threaded cylinder, a screening screen, a second sealing plug, a positioning post, and a second through hole. The inner wall of the externally threaded cylinder and the inner wall of the cylindrical cylinder are both in contact with the surface of the second internally threaded cylinder. The upper surface of the second internally threaded cylinder is fixedly connected to the bottom of the screening screen. The left and right sides of the second internally threaded cylinder are both fixedly connected to one end of the positioning post. The inner wall of the positioning groove and the upper surface of the nut are both in contact with the surface of the positioning post. The inner wall of the second internally threaded cylinder is threadedly connected to the surface of the second sealing plug. The second through hole is opened on the left side of the second internally threaded cylinder and is aligned with the first through hole.

[0008] The present invention is further configured such that the cylinder is located between the external threaded cylinder and the second sealing plug, the thickness of the cylinder is less than the thickness of the external threaded cylinder, and the distance between the cylinder and the external threaded cylinder is greater than the height of the positioning post.

[0009] The present invention is further configured such that the screening mesh has a circular hole inside, a cylinder is fitted into the circular hole, a cross-shaped scraper is fixedly connected to the bottom end of the cylinder, the upper surface of the cross-shaped scraper is fitted into the bottom of the screening mesh, a spring is fixedly connected to the upper surface of the cylinder, and a horizontal column is fixedly connected to the top end of the spring and the bottom of the conical cylinder.

[0010] The present invention is further configured such that the center of the cross-shaped scraper is on the same vertical line as the axis of the second internal threaded cylinder, and the tension of the spring on the cylinder is greater than the sum of the weight of the cylinder and the cross-shaped scraper.

[0011] The present invention is further configured such that a first indicator block is fixedly connected to the front side of the cylinder, and a second indicator block is fixedly connected to the front side of the second internally threaded cylinder, with the second indicator block located below the first indicator block.

[0012] The technical effects achieved by this utility model are as follows:

[0013] This utility model discloses a pipeline regulating valve that uses an external threaded cylinder, a cylindrical tube, a connecting column, a positioning groove, and a nut to fix a filter assembly inside the external threaded cylinder. Simultaneously, when the second through hole on the filter assembly is aligned with the first through hole, tap water below the partition plate can enter the filter assembly through both the first and second through holes and be filtered by a screening screen. When the second through hole is misaligned with the first through hole, the filter assembly can seal the first through hole. This allows the user to clean fine sand and rust from inside the filter assembly by misaligning the second and first through holes, ensuring that only tap water from inside the filter assembly flows out during cleaning, thus effectively reducing the amount of tap water flowing out of the valve body during cleaning.

[0014] This utility model discloses a pipeline regulating valve that uses the tension of a spring on a cylinder to make the cross-shaped scraper fit tightly against the screening screen. Furthermore, when the user rotates the filter assembly to offset the second through hole from the first through hole, the cross-shaped scraper can automatically scrape off the fine sand and rust adsorbed on the screening screen, making it more convenient for the user to clean the fine sand and rust adsorbed on the screening screen.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] like Figures 1 to 6 As shown, a pipeline regulating valve includes a valve body 1. A hollow partition plate 2 is fixedly connected to the inner wall of the valve body 1. A conical cylinder 3 is fixedly connected to the inner wall of the hollow partition plate 2. A first internally threaded cylinder 4 is fixedly connected to the inner wall of the valve body 1. A threaded post 5 is threadedly connected to the inner wall of the first internally threaded cylinder 4. A handle 6 is fixedly connected to the top of the threaded post 5. A first sealing plug 7 is fixedly connected to the bottom of the threaded post 5. The surface of the first sealing plug 7 is in contact with the inner wall of the conical cylinder 3. The bottom of the hollow partition plate 2 and the inner wall of the valve body 1 are both fixed. A threaded cylinder 8 is connected to the valve body 1. A first through hole 9 is provided on the left side of the threaded cylinder 8. A filter assembly 10 is fitted to the inner wall of the threaded cylinder 8. A cylinder 11 is fitted to the surface of the filter assembly 10. A connecting post 12 is fixedly connected to the surface of the cylinder 11 and the bottom of the valve body 1. A positioning groove 13 is provided at the bottom of the threaded cylinder 8. The inner wall of the positioning groove 13 is fitted to the surface of the filter assembly 10. A nut 14 is threaded to the surface of the threaded cylinder 8. The upper surface of the nut 14 is fitted to the bottom of the filter assembly 10.

[0027] The filter assembly 10 includes a second internally threaded cylinder 101, a screening screen 102, a second sealing plug 103, a positioning post 104, and a second through hole 105. The inner walls of the externally threaded cylinder 8 and the inner walls of the cylinder 11 are both in contact with the surface of the second internally threaded cylinder 101. The cylinder 11 is located between the externally threaded cylinder 8 and the second sealing plug 103. The thickness of the cylinder 11 is less than the thickness of the externally threaded cylinder 8. The upper surface of the second internally threaded cylinder 101 is fixedly connected to the bottom of the screening screen 102. The left and right sides of the second internally threaded cylinder 101... The sides are fixedly connected to one end of the positioning post 104. The inner wall of the positioning groove 13 and the upper surface of the nut 14 are in contact with the surface of the positioning post 104. The distance between the cylinder 11 and the external threaded cylinder 8 is greater than the height of the positioning post 104. The inner wall of the second internal threaded cylinder 101 is threadedly connected to the surface of the second sealing plug 103. The bottom of the second threaded cylinder can be sealed by the second sealing plug 103. The second through hole 105 is opened on the left side of the second internal threaded cylinder 101. The second through hole 105 is aligned with the first through hole 9.

[0028] It should be noted that when the user turns the handle 6, the first sealing plug 7 moves up or down through the cooperation of the threaded post 5 and the first internal threaded cylinder 4. By changing the distance between the first sealing plug 7 and the conical cylinder 3, the flow rate of the pipeline regulating valve is adjusted. At the same time, when the nut 14 is screwed onto the external threaded cylinder 8, the positioning post 104 can be fixed in the positioning groove 13 through the nut 14. The filter assembly 10 is fixed to the external threaded cylinder 8 through the cooperation of the positioning post 104 and the positioning groove 13. When the nut 14 is separated from the external threaded cylinder 8, the positioning post 104 can be moved out of the positioning groove 13, and the filter assembly 10 can be fixed to the external threaded cylinder 8. When the second through hole 105 on the second internal threaded cylinder 101 is aligned with the first through hole 9, the tap water below the partition plate can enter the filter assembly 10 through the first through hole 9 and the second through hole 105, and be filtered by the screen 102. When the first through hole 9 and the second through hole 105 are misaligned, the first through hole 9 can be sealed by the second internal threaded cylinder 101. When the nut 14 is separated from the external threaded cylinder 8, the nut 14 can be positioned and supported by the cylinder 11 and the connecting column 12. At the same time, when the nut 14 is fitted on the cylinder 11, the upper surface of the nut 14 is lower than the upper surface of the cylinder 11.

[0029] like Figures 1 to 7 As shown, the screening screen 102 has a circular hole 15 inside, and a cylinder 16 is fitted into the circular hole 15. A cross-shaped scraper 17 is fixedly connected to the bottom end of the cylinder 16. The upper surface of the cross-shaped scraper 17 is fitted into the bottom of the screening screen 102. A spring 18 is fixedly connected to the upper surface of the cylinder 16. A horizontal column 19 is fixedly connected to the top of the spring 18 and the bottom of the conical cylinder 3.

[0030] The center of the cross-shaped scraper 17 is on the same vertical line as the axis of the second internal threaded cylinder 101, and the tension of the spring 18 on the cylinder 16 is greater than the sum of the weights of the cylinder 16 and the cross-shaped scraper 17.

[0031] It should be noted that the tension of the spring 18 on the cylinder 16 makes the cross-shaped scraper 17 fit tightly against the screen 102. Furthermore, when the user rotates the filter assembly 10 to offset the second through hole 105 from the first through hole 9, the cross-shaped scraper 17 can automatically scrape off the fine sand and rust adsorbed on the screen 102.

[0032] like Figures 1 to 5 As shown, a first indicator block 20 is fixedly connected to the front of the cylinder 11, and a second indicator block 21 is fixedly connected to the front of the second internally threaded cylinder 101. The second indicator block 21 is located below the first indicator block 20.

[0033] It should be noted that when the first through hole 9 is aligned with the second through hole 105, the first indicator block 20 is aligned with the second indicator block 21. When the first through hole 9 is misaligned with the second through hole 105, the first indicator block 20 is misaligned with the second indicator block 21. Thus, by observing the first indicator block 20 and the second indicator block 21, it is possible to intuitively determine whether the second through hole 105 is aligned with the first through hole 9.

[0034] The working principle of this utility model is as follows: First, connect the pipe to the inlet and outlet of the valve body 1. Then, control the distance between the first sealing plug 7 and the conical cylinder 3 according to the water flow. When adjusting the distance between the conical cylinder 3 and the first sealing plug 7, first rotate the rotating block to make the threaded column 5 rotate. Then, through the cooperation of the threaded column 5 and the threaded cylinder, the first sealing plug 7 moves up or down.

[0035] When tap water passes through the regulating valve of the pipeline, the tap water first enters the filter assembly 10 through the first through hole 9 and the second through hole 105. Then, the fine sand and rust blocks in the tap water are filtered out through the screening screen 102. The filtered fine sand and rust blocks fall on the second sealing plug 103. The filtered tap water flows to the top of the partition plate through the conical tube 3 and flows out through the right side of the valve body 1.

[0036] When it is necessary to clean the fine sand and rust blocks inside the filter assembly 10, first, rotate the nut 14 to separate the nut 14 from the external threaded cylinder 8. Then, move the positioning pin 104 out of the positioning groove 13, and rotate the second internal threaded cylinder 101 to offset the first through hole 9 from the second through hole 105. At this time, close the first through hole 9 through the second internal threaded cylinder 101. Then, unscrew the second sealing plug 103 from the second threaded cylinder and clean the fine sand and rust blocks accumulated inside the second threaded cylinder.

[0037] After cleaning, screw the second sealing plug 103 into the second threaded cylinder. Then, by rotating the second internal threaded cylinder 101, the second through hole 105 is positioned below the first through hole 9, and the positioning pin 104 is aligned with the positioning groove 13. Then, the positioning pin 104 is inserted into the positioning groove 13, and the nut 14 is screwed onto the external threaded cylinder 8. At this time, the positioning pin 104 is fixed in the positioning groove 13 by the nut 14. Then, through the cooperation of the positioning pin 104 and the positioning groove 13, the filter assembly 10 is fixed in the external threaded cylinder 8, and the first through hole 9 is aligned with the second through hole 105.

[0038] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
