Abstract
Description
Technical Field
[0001] This utility model relates to the field of support device technology, specifically to a leak-proof sealing device for flanges of evaporative cooling inlet and outlet liquid pipes. Background Technology
[0002] As the core channel for the circulation of hot and cold media, the evaporator cold inlet and outlet pipes are subjected to long-term temperature fluctuations (typically -20℃ to 90℃), pressure shocks (0.1 to 1.6 MPa), and media corrosion (such as water, ethylene glycol solution, refrigerant, etc.) at their flange connections, making them a high-risk area for leakage. The design of flange sealing leak-proof devices needs to specifically address three core issues: aging of seals caused by temperature fluctuations, imbalance of sealing specific pressure caused by load fluctuations, and structural failure caused by media corrosion.
[0003] A prior art patent with publication number CN220816888U discloses a solution including an inner bushing and a connecting pipe. A sleeve is fixedly connected to the outer side of the inner bushing, and a first connecting plate is fixedly connected to the outer side of the sleeve. A second connecting plate is integrally formed on one side of the connecting pipe, corresponding to the first connecting plate. An inner bushing ring and a threaded sleeve are integrally formed on one side of the inner bushing, with the threaded sleeve located outside the inner bushing ring. A threaded ring is rotatably connected to one side of the second connecting plate, and the threaded ring is threadedly connected to the outer side of the threaded sleeve. This flange sealing and leak-proof device improves the leak-proof effect of the flange during connection, facilitates use, prevents loosening, improves the stability of the fixation, and facilitates installation and disassembly.
[0004] As existing devices are used, the shortcomings of this technology have gradually become apparent, mainly in the following aspects:
[0005] After the on-site assembly was completed, when the customer connected the inlet and outlet pipes, because there were no support points on the outside of the enclosure, the construction workers could directly step on the pipes. The weight was applied to the connection between the flange and the enclosure, causing the sealing flange to shift and deform, resulting in water leakage.
[0006] As can be seen from the above, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content
[0007] To address the shortcomings of existing technologies, this utility model provides a leak-proof sealing device for the flanges of evaporative cooling inlet and outlet liquid pipes. This device solves the problem that, in traditional technologies, after the on-site assembly of the tank, when customers connect the inlet and outlet liquid pipes, the lack of external support points on the tank means that construction workers can directly step on the pipes, applying weight to the connection between the flange and the tank, causing the sealing flange to shift and deform, resulting in water leakage.
[0008] To achieve the above objectives, the present invention provides the following technical solution.
[0009] An evaporative cooling inlet and outlet pipe flange sealing leak-proof device includes an evaporative cooling outer box. The evaporative cooling outer box is detachably connected to a horizontally arranged inlet and outlet pipe. An inclined support assembly is fixedly installed at an angle upward below the inlet and outlet pipes. The upper end of the inclined support assembly is fixedly connected to a support seat connected to the inlet and outlet pipes. The length of the inclined support assembly is adjustable along its extension direction, and a triangular reinforced support structure is formed between the evaporative cooling outer box, the inlet and outlet pipes, and the inclined support assembly.
[0010] As an optimized solution, the two ends of the inlet and outlet pipes are respectively fixed with connecting flanges, and an outer sealing ring and an inner sealing ring are arranged side by side from the outside to the inside between the connecting flanges and the mating surface of the evaporative cooling outer box.
[0011] As an optimized solution, the support includes an arc-shaped seat, the lower surface of the inner wall of the arc-shaped seat abutting against the lower surface of the inlet / outlet pipe.
[0012] As an optimized solution, the arc-shaped seat has horizontal threaded connections on the opposite outer walls near the opening end, with the ends of the horizontal limiting bolts abutting against the outer walls of the inlet and outlet pipes.
[0013] As an optimized solution, the spacing between the upper openings of the arc-shaped seat is smaller than the diameter of the arc-shaped seat.
[0014] As an optimized solution, the inclined support assembly includes an inclined support tube fixedly connected to the support tube. An adjusting cylinder is coaxially rotatably connected to the upper end of the support tube. A connecting column that slides axially is provided inside the adjusting cylinder. The upper end of the connecting column is fixedly connected to the lower end of the arc-shaped seat.
[0015] As an optimized solution, a connecting plate is vertically fixed to the side wall of the evaporative cooling outer box, and the lower end of the support tube is fixed to the connecting plate.
[0016] As an optimized solution, an end plate is fixedly connected to the lower end of the adjusting cylinder, and a support column is fixedly connected to the lower end of the end plate. The support column is rotatably inserted into the upper end of the support tube.
[0017] As an optimized solution, the outer wall of the connecting column is provided with an external thread section, and the inner wall of the adjusting cylinder is provided with an internal thread that matches the external thread section.
[0018] As an optimized solution, a locking nut is also threaded onto the external thread section, and the locking nut abuts against the upper end of the adjusting cylinder.
[0019] As an optimized solution, two annular grooves are respectively opened from the outside to the inside on the mating surface of the connecting flange, and the outer sealing ring and the inner sealing ring are respectively fitted into the two annular grooves.
[0020] As an optimized solution, both the connecting plate and the connecting flange are surrounded by several fixing holes, and bolts are inserted into the fixing holes. The side wall of the evaporator cooling outer box is provided with threaded grooves that match the bolts.
[0021] Compared with the prior art, the beneficial effects of this utility model are:
[0022] By installing an outer sealing ring and an inner sealing ring from the inside out on the connecting flange of the inlet and outlet pipes, the sealing performance of the inlet and outlet ports on the side wall of the evaporator cooling box can be improved.
[0023] By installing an inclined support assembly on the evaporative cooling outer casing, and using the arc-shaped seat of the inclined support assembly to support the inlet and outlet liquid pipes, it is possible to prevent the distal ends of the inlet and outlet liquid pipes from sagging due to gravity, thus ensuring the connection stability between the connecting flange and the evaporative cooling outer casing and reducing the occurrence of water leakage.

Detailed Implementation
[0028] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.
[0029] like Figure 1 and Figure 2As shown, the evaporative cooling inlet and outlet pipe flange sealing anti-leakage device includes an evaporative cooling outer box 1. A horizontally arranged inlet and outlet pipe 2 is detachably connected to the evaporative cooling outer box 1. An inclined support assembly is fixedly installed at the position below the inlet and outlet pipe 2. A support seat connected to the inlet and outlet pipe 2 is fixedly connected to the upper end of the inclined support assembly. The length of the inclined support assembly is adjusted along its extension direction, and a triangular reinforced support structure is formed between the evaporative cooling outer box 1, the inlet and outlet pipe 2, and the inclined support assembly.
[0030] The inlet and outlet pipes 2 are respectively fixed with connecting flanges 3. The connecting flanges 3 and the evaporator cooling outer box 1 are provided with an outer sealing ring 4 and an inner sealing ring 5 in parallel from the outside to the inside.
[0031] The support includes an arc-shaped seat 10, the lower surface of the inner wall of the arc-shaped seat 10 abutting against the lower surface of the inlet / outlet pipe 2.
[0032] The arc-shaped seat 10 has horizontal threaded connections on its opposite outer walls near the opening end. The ends of the horizontal limiting bolts 11 abut against the outer walls of the inlet and outlet pipes 2. By using the two horizontal limiting bolts 11 to abut against the opposite side walls of the inlet and outlet pipes 2, the lateral position of the inlet and outlet pipes 2 and the arc-shaped seat 10 is limited, preventing the inlet and outlet pipes 2 from swinging laterally.
[0033] The gap between the upper openings of the arc-shaped seat 10 is smaller than the diameter of the arc-shaped seat 10, which makes it easier to limit the area above the middle of the inlet and outlet pipes 2 by means of the transverse limiting bolts 11.
[0034] The inclined support assembly includes an inclined support tube 7, an adjusting cylinder 8 coaxially rotatably connected to the upper end of the support tube 7, and a connecting column 9 that slides axially inside the adjusting cylinder 8. The upper end of the connecting column 9 is fixedly connected to the lower end of the arc-shaped seat 10.
[0035] A connecting plate 6 is vertically fixed to the side wall of the evaporative cooling outer box 1, and the lower end of the support pipe 7 is fixed to the connecting plate 6.
[0036] A reinforcing rod 14, which is fixed to the outer wall of the support tube 7, is horizontally fixed to the connecting plate 6.
[0037] An end plate 12 is fixedly connected to the lower end of the adjusting cylinder 8, and a support column 13 is fixedly connected to the lower end of the end plate 12. The support column 13 is rotatably inserted into the upper end of the support tube 7.
[0038] The outer wall of the connecting column 9 is provided with an external thread section, and the inner wall of the adjusting cylinder 8 is provided with an internal thread that matches the external thread section. This allows the extension length of the support column 13 to be adjusted by rotating the adjusting cylinder 8 when the connecting plate 6 is fixed and the arc seat 10 needs to be adjusted to support the inlet and outlet pipes, thereby abutting the arc seat 10 against the inlet and outlet pipes 2.
[0039] A locking nut is also threaded onto the external thread section. The locking nut abuts against the upper end of the adjusting cylinder 8. After the support column 13 is adjusted to the correct position, the locking nut is tightened to prevent the support column 13 from rotating on its own and the adjusting cylinder 8.
[0040] Two annular grooves are formed from the outside to the inside on the mating surface of the connecting flange 3, and the outer sealing ring 4 and the inner sealing ring 5 are respectively fitted into the two annular grooves.
[0041] Both the connecting plate 6 and the connecting flange 3 are surrounded by several fixing holes, and bolts are inserted into the fixing holes. The side wall of the evaporator cooling outer box 1 is provided with threaded grooves that match the bolts.
[0042] The working principle of this device is as follows:
[0043] By setting an outer sealing ring 4 and an inner sealing ring 5 from the inside to the outside on the connecting flange of the inlet and outlet pipes 2, the sealing performance of the inlet and outlet ports on the side wall of the evaporator cooling outer box 1 can be improved.
[0044] By setting an inclined support assembly on the evaporative cooling outer casing 1, and using the arc-shaped seat 10 of the inclined support assembly to support the inlet and outlet pipes 2, it is possible to prevent the distal end of the inlet and outlet pipes 2 from sagging due to gravity, thus ensuring the connection stability between the docking flange and the evaporative cooling outer casing 1 and reducing the occurrence of water leakage.
[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
