Description

Technical Field

[0001] This utility model relates to the field of gas filtration, specifically a high-precision gas pressure regulator. Background Technology

[0002] Gas pressure regulation refers to the process of adjusting gas pressure to maintain it within a suitable range to ensure the safe and stable operation of gas equipment. Since different gas equipment, pipelines, and users require different gas pressures, pressure regulation systems ensure that gas does not cause accidents or equipment malfunctions due to excessively high or low pressure during its delivery to the end user.

[0003] According to application number 201920866322.2, a gas pressure regulator is disclosed, belonging to the field of gas pressure regulators. The gas pressure regulator includes a valve body, with an inlet connector at the right end and an outlet connector at the upper end. A flange is provided at the left end of the valve body, and an end cap is installed on the left end. A threaded sleeve is provided in the middle of the left end of the end cap, and a threaded head is threadedly connected inside the threaded sleeve. A guide groove is provided inside the threaded head, and a guide rod is slidably sleeved inside the guide groove. A piston is fixedly connected to the right end of the guide rod. A pressure regulating sleeve is threadedly connected inside the inlet connector. It uses high-pressure gas to push the piston to move, allowing the gas to enter the cavity inside the valve body through a second vent groove, thus reducing pressure. Furthermore, the cooperation between the threaded head and the threaded sleeve allows for the compression of a spring, causing elastic deformation and pressure regulation. By designing a spring and a limiting block, the limiting block can be locked in the limiting groove, preventing the threaded head from rotating and ensuring the stability of pressure regulation.

[0004] The above-mentioned solutions still have certain shortcomings in actual use; however, in actual use, due to the presence of impurities and particulate matter in the pipeline, the working efficiency and accuracy of the pressure regulator will be affected, and may even lead to direct equipment failure. Therefore, we provide a high-precision filtered gas pressure regulator. Utility Model Content

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.

[0023] like Figure 1-3 As shown, this utility model provides a technical solution: a high-precision gas pressure regulator, including a regulator body 1, a sealing plate 2 on the left side of the regulator body 1, a fixing block 11 fixedly connected inside the regulator body 1, two hooks 14 installed inside the fixing block 11, and a filter screen 15 hung on the two hooks 14. A second magnet 19 is fixedly connected to the outer surface of the filter screen 15. A pull rod 6 is slidably connected to the outer surface of the sealing plate 2, and a sealing block 16 is fixedly connected to the right end of the pull rod 6. A first magnet 17 is fixedly connected to the outer surface of the sealing block 16, and the first magnet 17 and the second magnet 19 are attracted to each other. Through the filter screen 15 hung between the two hooks 14, impurities can be filtered to a certain extent, thereby ensuring that there are no impurities or particulate matter in the pipeline, thus not affecting the subsequent working efficiency and accuracy of the device, and ensuring the normal use of the device.

[0024] A rubber pad 8 is slidably connected to the outer surface of the pull rod 6, and one side of the rubber pad 8 is fixedly connected to the inner wall of the sealing plate 2, which can limit the movement of the pull rod 6 to a certain extent and ensure the subsequent use effect of the pull rod 6.

[0025] A spring 13 is installed between the rubber pad 8 and the sealing block 16, and the spring 13 is sleeved on the outer surface of the pull rod 6. The spring 13 can provide a certain pulling force to the pull rod 6, thereby ensuring the stability of the pull rod 6 during subsequent use.

[0026] The left end of the pull rod 6 is fixedly connected to a circular plate 3, and the outer surface of the sealing plate 2 is fixedly connected to two electric push rods 7. The output end of the electric push rod 7 is fixedly connected to the outer surface of the circular plate 3, which can realize the movement of the pull rod 6, thereby realizing the opening of the device and ensuring the normal use of the subsequent device.

[0027] The outer surface of the pressure regulator body 1 has two openings 12, and an input pipe 5 and an output pipe 4 are respectively installed at the openings 12. The outer surface of the fixing block 11 has a discharge port 18, which realizes the connection between this device and other structures and improves the practicality of this device in actual use.

[0028] The outer surface of the sealing plate 2 is threaded with two bolts 9, and the outer surface of the pressure regulator body 1 is provided with two threaded holes 10.
