The two second switch valves are respectively arranged at both ends of the filtering mechanism, and the two second switch valves communicate with the throttling pipe main body. The filtering structure in this patent solution is too simple, the contact time between the water flow and the filtering structure is short, the flow path of the water flow in the filtering structure is also short, and the water flow quickly passes through the filter material, resulting in the impurities in the water flow not being fully intercepted by the filter material, so the filtering effect is poor, the water quality entering the cooling tower cannot be guaranteed, and the intercepted impurities cannot be conveniently cleaned. Therefore, it is necessary to design a cooling tower water supply pipeline for the above problems. Content of the Utility Model

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4, the utility model provides a technical solution: a cooling tower water supply pipeline, including a first water supply pipe 1, a bottom plate 2, a support plate 3, a positioning hole 4, a locking bolt 5, a locking nut 6, a mounting hole 7, a first control valve 8, a mounting seat 9, a second water supply pipe 10, a second control valve 11, a positioning bolt 12, a sealing cylinder 13, a sealing ring 14, a middle partition plate 15, a mesh frame 16 and a filter material 17. A bottom plate 2 is arranged at the bottom end of the horizontal part of the first water supply pipe 1. The bottom side of the first water supply pipe 1 and the bottom plate 2 are both attached to the top of the support plate 3. A positioning hole 4 is horizontally penetrated through the vertical part of the support plate 3. A locking bolt 5 is penetrated and installed in the positioning hole 4, and a locking nut 6 is installed at the end of the locking bolt 5. A mounting hole 7 is opened at the bottom end of the support plate 3. The above structural design enables the relatively long first water supply pipe 1 to be stably supported, avoiding low-frequency resonance and reducing the impact of water hammer effect during valve opening and closing on the pipeline. The support plates 3 are symmetrically distributed about the center of the bottom plate 2, and the side view shape of the support plate 3 is an "L" shape. The above structural design enables the support plate 3 to stably support and position the bottom plate 2. The support plates 3 are equally spaced at the bottom end of the horizontal part of the first water supply pipe 1. The length of the contact part between the symmetric support plate 3 and the bottom plate 2 is greater than 1 / 3 of the width of the bottom plate 2. The above structural design utilizes the equally spaced distribution method and sufficient contact area to ensure the support effect of the support plate 3 on the first water supply pipe 1;

[0023] When installing the first water supply pipe 1, first, as Figure 1 shown, the support plates 3 are equally spaced and installed at the bottom end of the long-distance conveying end of the first water supply pipe 1 to support the first water supply pipe 1. During normal operation, hot water flows upward from the first water supply pipe 1 and enters the Figure 3 right-side space inside the sealing cylinder 13. The water flow passes through the mesh frame 16 on the right side and contacts the filter material 17 inside for impurity filtration. Then, under the action of water pressure, the water flow continues to flow upward to the top of the middle partition plate 15 and flows leftward to the mesh frame 16 on the left side, passes through the mesh frame 16 on the left side and contacts the filter material 17 inside for impurity filtration. The water flow flows downward and enters the cooling tower through the second water supply pipe 10;

[0024] A first control valve 8 is installed on the first water supply pipe 1. The end of the first water supply pipe 1 is fixedly connected to one side of the mounting seat 9. The other side of the mounting seat 9 is fixedly connected to the end of the second water supply pipe 10. A second control valve 11 is installed on the second water supply pipe 10. A sealing cylinder 13 is installed on the top of the mounting seat 9 through a positioning bolt 12. The top end of the mounting seat 9 and the bottom end of the sealing cylinder 13 are in snap connection. The front view sectional shape of the mounting seat 9 is "convex". The above structural design ensures that the top end of the mounting seat 9 and the sealing cylinder 13 can be stably aligned and connected, and has strong sealing performance. A sealing ring 14 is installed on the edge of the top surface of the mounting seat 9. A middle partition 15 is fixed at the center of the top surface of the mounting seat 9. The second water supply pipe 10 and the first water supply pipe are symmetrically distributed about the center of the middle partition 15. The center of the middle partition 15 and the center of the mounting seat 9 are on the same vertical plane. The above structural design separates the top ends of the second water supply pipe 10 and the first water supply pipe into the spaces on both sides of the middle partition 15 in the sealing cylinder 13, which can extend the retention time of water in the sealing cylinder 13 and ensure the filtering effect;

[0025] The side surface of the middle partition 15 is in contact with the middle part of the inner wall of the sealing cylinder 13. The distance between the top surface of the middle partition 15 and the inner top surface of the sealing cylinder 13 is greater than 1 / 6 of the overall height of the middle partition 15. The front and rear sides of the middle partition 15 are arc-shaped. The front and rear side surfaces of the middle partition 15 are in close contact with the inner side surface of the sealing cylinder 13. The above structural design ensures the partitioning effect of the middle partition 15 and allows water flow to only flow smoothly through the top of the middle partition 15, extending the flow distance of water in the sealing cylinder 13. Two wire frames 16 are fixedly installed on both sides of the inner wall of the sealing cylinder 13. A filter material 17 is arranged in the wire frame 16. The overall height of the wire frame 16 is greater than 3 / 4 of the overall height of the sealing cylinder 13. The wire frame 16 is made of fine stainless steel wire mesh. The straight side surface of the wire frame 16 is in close contact with the straight side surface of the middle partition 15. The above structural design ensures that water flow can smoothly pass through the wire frame 16 and contact the filter material 17 in the wire frame 16 for a long time to ensure the filtering and impurity removal effect;

[0026] When it is necessary to clean the filter material 17 in the wire frame 16, close the first control valve 8 and the second control valve 11, remove the positioning bolts 12 installed at equal angles at the bottom outside of the sealing cylinder 13, move the sealing cylinder 13 upward to separate it from the mounting seat 9, clean or replace the symmetrically distributed wire frames 16 and filter materials 17 in the sealing cylinder 13, then install the sealing cylinder 13 in place and connect the sealing cylinder 13 to the mounting seat 9 through the positioning bolts 12, and then the first control valve 8 and the second control valve 11 can be opened, and the whole device can be used normally.

[0027] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
