[0024] In one embodiment, such as Figures 1-3 As shown, a dual-channel pressure reducing valve assembly for a gas compressor includes:

[0025] Install valve seat 1;

[0026] The pressure reducing valve body 2 is disposed on the upper end face of the mounting valve seat 1;

[0027] The intake pipe 3 is located on one side of the pressure reducing valve body 2;

[0028] The air outlet pipe 4 is located on the other side of the pressure reducing valve body 2;

[0029] A pressure stabilizing component is used to stabilize the pressure of the outlet pipe 4 and is installed on the inlet pipe 3 and the outlet pipe 4. The pressure stabilizing component includes a pressure stabilizing pipe 8, which is installed on one side of the pressure reducing valve body 2. A connecting piece is provided between the inlet pipe 3, the outlet pipe 4 and the pressure stabilizing pipe 8. A pressure stabilizing component is installed inside the pressure stabilizing pipe 8.

[0030] The connector includes a first connecting pipe 5, which is installed on the air outlet pipe 4. A first connecting plate 6 is connected to the first connecting pipe 5. A first through pipe 7 is connected to the first connecting plate 6. The other end of the first through pipe 7 is connected to a pressure stabilizing pipe 8. The other end of the pressure stabilizing pipe 8 is connected to a second through pipe 9. The other end of the second through pipe 9 is connected to a second connecting plate 10. The lower end of the second connecting plate 10 is connected to a second connecting pipe 11, which is installed on the air inlet pipe 3.

[0031] The voltage regulator includes four sets of fixing blocks 12, which are respectively connected to both sides of the inner wall of the voltage regulator tube 8. Two sets of fixing rods 13 are provided on the side walls of the four sets of fixing blocks 12. Sliding circular plates 14 are slidably mounted on the two sets of fixing rods 13. A set of springs 15 is sleeved on the outer side of each set of fixing rods 13. One end of each set of springs 15 is connected to the side wall of the two sets of fixing blocks 12, and the other end of each set of springs 15 is connected to a set of circular plates 16. The two sets of circular plates 16 are connected to the side wall of the sliding circular plates 14. A vent hole 17 is provided on the inner wall of the voltage regulator tube 8. The diameter of the vent hole 17 is larger than the diameter of the sliding circular plates 14.

[0032] Specifically, in use, the inlet pipe 3 is connected to the high-pressure gas cylinder, and the outlet pipe 4 is connected to the breathing mask. After the high-pressure gas is processed by the pressure reducing valve body 2, it enters the outlet pipe 4 and then the breathing mask. When the gas pressure inside the outlet pipe 4 is high, the gas enters the first connecting pipe 7 through the first connecting pipe 5. The first connecting pipe 7 delivers the gas to the pressure stabilizing pipe 8, and then the gas pushes the sliding disc 14 to slide on the two sets of fixed rods 13, simultaneously compressing the two sets of springs 15, causing the gas to enter the vent 17, then the second connecting pipe 9, and subsequently... The second connecting pipe 11 re-enters the interior of the intake pipe 3, thereby enabling pressure stabilization of the outlet pipe 4. When the gas pressure inside the outlet pipe 4 stabilizes, the sliding disc 14 resets under the elastic action of the spring 15. By setting up a pressure stabilizing assembly consisting of a pressure stabilizing pipe 8, a connecting piece, and a pressure stabilizing piece, when the gas pressure inside the outlet pipe 4 is high, the gas pushes the sliding disc 14 to connect with the vent 17 and then re-enters the interior of the intake pipe 3, thereby enabling pressure stabilization of the outlet pipe 4, maintaining stable gas pressure inside the outlet pipe 4, improving the working efficiency of the pressure reducing valve body 2, and making it quite practical.

[0033] like Figures 1-3 As shown, each of the two side walls of the pressure stabilizing pipe 8 has a set of insertion holes 18. One end of the first connecting pipe 7 and the second connecting pipe 9 are respectively inserted into the two sets of insertion holes 18. The insertion holes 18 facilitate the connection of the first connecting pipe 7, the second connecting pipe 9 and the pressure stabilizing pipe 8. The mounting valve seat 1 has multiple sets of mounting holes 19 at equal intervals. The mounting holes 19 facilitate the installation and connection of the mounting valve seat 1. The first connecting plate 6 and the second connecting plate 10 are each provided with multiple sets of mounting bolts 20. The multiple sets of mounting bolts 20 are respectively connected to the first connecting pipe 5 and the second connecting pipe 11. The multiple sets of mounting bolts 20 facilitate the installation and disassembly of the first connecting plate 6 and the second connecting plate 10.

[0034] The above embodiment discloses a dual-channel pressure reducing valve assembly for a gas compressor. In use, the inlet pipe 3 is connected to a high-pressure gas cylinder, and the outlet pipe 4 is connected to a breathing mask. When the high-pressure gas is processed by the pressure reducing valve body 2, it enters the interior of the outlet pipe 4 and then enters the breathing mask for use. When the gas pressure inside the outlet pipe 4 is high, the gas enters the interior of the first through pipe 7 through the first connecting pipe 5. The first through pipe 7 delivers the gas to the interior of the pressure stabilizing pipe 8. Then, the gas pushes the sliding disc 14 to slide on the two sets of fixed rods 13, while squeezing the two sets of springs 15, so that the gas enters the interior of the vent 17, and then enters the interior of the second through pipe 9. Subsequently, it re-enters the interior of the inlet pipe 3 through the second connecting pipe 11, thereby enabling pressure stabilization of the outlet pipe 4. When the gas pressure inside the outlet pipe 4 is stable, the sliding disc 14 resets under the elastic action of the spring 15, which is convenient and practical.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
