Description

Technical Field

[0001] This utility model relates to the field of regeneration valves, specifically a locomotive air source outlet regeneration valve. Background Technology

[0002] The locomotive air source purification and drying device uses a desiccant (molecular sieve, activated alumina) to adsorb moisture and oil mist in compressed air, drying the air before supplying it to the locomotive's air source system. The regeneration process is achieved by backflushing with clean, dry air, restoring drying capacity through desorption (releasing adsorbed moisture). Generally, regeneration is carried out using a dual-tower switching principle, with one tower adsorbing and the other regenerating, thus failing to achieve uninterrupted air supply. Therefore, those skilled in the art have provided a locomotive air source outlet regeneration valve to solve the problems mentioned in the background art. Utility Model Content

[0003] The purpose of this utility model is to provide a locomotive air source outlet regeneration valve to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a locomotive air source outlet regeneration valve, comprising a regeneration valve body, wherein multiple holes are irregularly arranged at the bottom of the regeneration valve body, and end caps are fixedly connected to both sides of the regeneration valve body, a regeneration valve action piston is embedded in the regeneration valve body, and regeneration valve seats are fixedly connected to both ends of the regeneration valve action piston, a regeneration valve assembly is embedded in the regeneration valve body, and the regeneration valve assembly is located on one side of the regeneration valve action piston, and an air pipe is threadedly connected to one side of the regeneration valve body.

[0005] As a further embodiment of this utility model: a plurality of mounting holes are provided through a rectangular opening on one side of the end cap, and a rod is inserted through each of the plurality of mounting holes, and the rod penetrates into the body of the regeneration valve, and the body of the regeneration valve is engaged with the plurality of rods.

The first connecting hole is fitted with a regeneration valve action piston and two regeneration valve seats. The second connecting hole is fitted with a regeneration valve assembly. A threaded connecting hole is connected through one side of the first connecting hole, and the air pipe is threaded through and connected in the threaded connecting hole.

[0007] As a further improvement of this utility model: both ends of the second connecting hole are fitted with a third O-ring, and the inner wall of the third O-ring is in contact with the outer wall of the regeneration valve assembly.

[0008] As a further improvement of this utility model: a first O-ring and a second O-ring are respectively embedded in multiple holes at the bottom of the regeneration valve body, and the diameter of the first O-ring is smaller than the diameter of the second O-ring.

[0009] As a further embodiment of this utility model: two semi-circular grooves are symmetrically opened on both sides of the regeneration valve body, and through holes are opened at the bottom of the two semi-circular grooves.

[0010] As a further embodiment of this utility model: an air inlet is provided on the outer wall of the first connecting hole, the air inlet is connected to the first connecting hole, and the air inlet is provided through the space between the first connecting hole and the second connecting hole.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] Multiple holes below the regeneration valve body can be used to connect the gas supply pipe, which can then be connected to the location where compressed air needs to be supplied. When switching to Tower 2, the clean compressed air from Tower 2 flows to the right end of the reversing valve and the right end of the regeneration valve body. The sliders of the reversing valve and the regeneration valve body move to the left, and the gas can only flow upward. A small portion of the gas flows through the pressure regulating valve, and then the pressure-regulated gas flows into the inlet of the gas pipe installed on the regeneration valve body. At this time, the regeneration valve action piston inside the regeneration valve body will move to the left regeneration valve seat. This regeneration valve action piston will push the fourth O-ring on the left to move towards the left regeneration valve seat. At this time, the regeneration valve seat at this end will be closed, and the gas flows out from the right side of the regeneration valve body. The regenerated gas that flows out will then be supplied to Tower 1 for regeneration.

[0013] This invention is simple to use. The regeneration valve assembly, together with the regeneration valve piston and the regeneration valve seat, forms a complete assembly to control the left and right airflow direction. The position of the compressed airflow direction can be controlled by adjusting the left and right of the regeneration valve piston in the valve body. Then, the regeneration valve piston is adjusted left and right to repeatedly circulate the first and second towers for regeneration, thereby achieving an uninterrupted air supply.

[0022] Please see Figures 1-6 In this embodiment of the present invention, a locomotive air source outlet regeneration valve includes a regeneration valve body 1. The bottom of the regeneration valve body 1 has multiple irregularly arranged holes. Both sides of the regeneration valve body 1 are fixedly connected to end caps 4. The regeneration valve body 1 is embedded with a regeneration valve action piston 14. Both ends of the regeneration valve action piston 14 are fixedly connected to regeneration valve seats 12. The regeneration valve body 1 is embedded with a regeneration valve assembly 15, and the regeneration valve assembly 15 is located on one side of the regeneration valve action piston 14. One side of the regeneration valve body 1 is threadedly connected to an air pipe 8.

[0023] In this embodiment, a plurality of mounting holes 11 are rectangularly through-holes on one side of the end cap 4, and a rod 5 is inserted through each of the plurality of mounting holes 11. The rod 5 penetrates into the regeneration valve body 1, and the regeneration valve body 1 is engaged with the plurality of rods 5.

[0024] In this embodiment, a second connection hole 17 and a first connection hole 9 are respectively provided on one side of the regeneration valve body 1. The first connection hole 9 is fitted with a regeneration valve action piston 14 and two regeneration valve seats 12. The second connection hole 17 is fitted with a regeneration valve assembly 15. A threaded connection hole 16 is connected through one side of the first connection hole 9, and the air pipe 8 is threadedly connected through the threaded connection hole 16.

[0025] In this embodiment, a third O-ring 10 is embedded at both ends of the second connection hole 17, and the inner wall of the third O-ring 10 is in contact with the outer wall of the regeneration valve assembly 15.

[0026] In this embodiment, a first O-ring 6 and a second O-ring 7 are respectively embedded in multiple holes at the bottom of the regeneration valve body 1, and the diameter of the first O-ring 6 is smaller than the diameter of the second O-ring 7.

[0027] In this embodiment, two semi-circular grooves 2 are symmetrically opened on both sides of the regeneration valve body 1, and through holes 3 are opened at the bottom of the two semi-circular grooves 2. Two fourth O-rings 13 are symmetrically fixed on the outer walls of the two regeneration valve action pistons 14.

[0028] In this embodiment, an air inlet 18 is provided on the outer wall of the first connecting hole 9. The air inlet 18 is connected to the first connecting hole 9 and is provided between the first connecting hole 9 and the second connecting hole 17.

[0029] The working principle of this utility model is as follows: Multiple holes below the regeneration valve body 1 can be used to connect to a gas delivery pipe. This gas delivery pipe can then be connected to the location where compressed air needs to be delivered. When switching to tower two, the clean compressed air from tower two flows to the right end of the reversing valve and the right end of the regeneration valve body 1. The sliders of the reversing valve and the regeneration valve body 1 move to the left, allowing the gas to flow upwards. A small portion of the gas flows through the pressure regulating valve, and then the regulated gas flows into the inlet of the gas pipe 8 installed on the regeneration valve body 1. At this time, the regeneration valve action piston 14 inside the regeneration valve body 1 moves to the left regeneration valve seat 12. This regeneration valve action piston 14 pushes the fourth O-ring 13 on the left towards the left regeneration valve seat 12, at which point the regeneration valve seat 12 at that end is closed, and the gas flows out from the right side of the regeneration valve body 1. The gas then flows out... The regenerated gas is supplied to Tower 1 for regeneration. Conversely, when switching to Tower 1, the clean compressed air from Tower 1 flows to the left end of the reversing valve and the left end of the regeneration valve body 1. The reversing valve and the regeneration valve body 1 move to the right, and the gas can only flow upward. A small portion of the gas passes through the pressure regulating valve and flows into the middle inlet of the gas pipe 8 on the upper part of the regeneration valve body 1. At this time, the regeneration valve piston 14 inside the regeneration valve body 1 moves to the right regeneration valve seat 12. The regeneration valve piston 14 pushes the fourth O-ring 13 on the right to move towards the right regeneration valve seat 12. At this time, the regeneration valve seat 12 at this end will be closed, and the gas flows out from the left side of the regeneration valve body 1. The regenerated gas that flows out is supplied to Tower 2 for regeneration. In this way, through the repeated cycle of regeneration of the two towers, an uninterrupted air supply is achieved.
