Abstract
Description
Technical Field
[0001] This utility model relates to the field of expansion tank technology, specifically an 8L energy storage liquid-cooled expansion tank. Background Technology
[0002] Expansion tanks are important components in HVAC systems, hot water heating systems, and central air conditioning water systems. Their core function is to contain and compensate for the volume expansion and contraction of water caused by temperature changes in the system, thereby ensuring stable system operation. When the system water temperature rises, the water expands and its volume increases. The expansion tank provides space to accommodate this increased volume, preventing the system pressure from becoming too high. Conversely, when the water temperature drops and its volume contracts, the expansion tank can replenish the system with water, preventing the pressure from becoming too low and creating a vacuum or drawing in air, thus maintaining stable system pressure. In addition, the expansion tank can also help expel air released during system operation, which helps reduce air lock and oxidation corrosion.
[0003] Existing expansion tanks typically have expansion pipes directly exposed to the outside, lacking impact protection, and the pipe connections are prone to loosening and leakage. In terms of installation adaptability, many existing devices have fixed and non-adjustable mounting bases, making it difficult to flexibly adapt to different rack sizes or space layouts, thus limiting their application scenarios.

[0010] As a further embodiment of this utility model: the expansion tube protection assembly includes a transparent protective shell disposed outside the expansion tube, an infinite clamp is fixedly snapped onto the surface of the expansion tube, a locking rod is rotatably connected to the side of the expansion tank near the expansion tube, a limiting plate is fixedly connected to the side of the transparent protective shell, a limiting groove is formed on the surface of the limiting plate, the width of the locking rod is adapted to the width of the limiting groove, and the locking rod abuts against the outer surface of the limiting plate by rotating 90 degrees on one side.
[0011] As a further improvement of this utility model: the sensor is a pressure sensor, and the sensing end of the sensor is connected to the inside of the expansion tank to monitor the pressure parameters inside the expansion tank.
[0012] As a further improvement of this utility model, the extension rod can slide along the groove to adjust the relative position between the connecting base plate and the fixed base, thus adapting to different installation requirements.
[0013] As a further improvement of this utility model, the stepless clamp is used to securely connect the expansion pipe to the expansion tank, preventing the expansion pipe from loosening.
[0014] As a further improvement of this utility model: the transparent protective shell is made of a transparent material that is resistant to high and low temperatures, and the locking lever is used to lock the transparent protective shell to provide stability.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] In this invention, the extension rod of the fixed adjustment base can be slidably adjusted along the slide groove, so that the relative position of the connecting base plate and the fixed base can be adapted according to the actual installation environment, which improves the compatibility and stability of the equipment in different specifications of racks or installation spaces and simplifies the installation process.
[0017] The expansion tube protection assembly, through the combination of a transparent protective shell and an infinite clamp, not only physically protects the expansion tube from external impacts and wear, but also facilitates intuitive observation of the internal condition of the tube and the sealing performance of the connection. The cooperation between the locking lever and the limiting plate ensures the stability of the protective shell. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.
[0025] Reference Figures 1 to 5 In this embodiment of the utility model, the energy storage liquid-cooled 8L expansion tank includes: an expansion tank 1, a fixing clamp 2, a steam valve 3, a fixing adjustment base 4, an expansion pipe protection assembly 5, an expansion pipe 6, a sensor base 7, and a sensor 8. The expansion tank 1 has a capacity of 8L, is made of carbon steel plate, and its cross-sectional shape can be circular or rectangular. The surface of the tank is treated with anti-corrosion.
[0026] A steam valve 3 is fixedly installed above the expansion tank 1 to control the pressure inside the expansion tank 1. When the internal pressure of the expansion tank 1 rises and exceeds the opening pressure setting value of the steam valve 3, the steam valve 3 will automatically open to discharge excess gas or steam until the pressure returns to normal, thereby preventing damage due to overpressure.
[0027] Two sets of fixing clamps 2 are mechanically fastened to the surface of the expansion tank 1. The fixing clamps 2 are preferably made of metal and have sufficient mechanical strength and corrosion resistance. A fixing adjustment base 4 is fixedly connected to the bottom of each set of fixing clamps 2. The fixing adjustment base 4 is used to fix and adjust the installation position of the expansion tank 1. It includes a fixing base 41. Fixing side plates 42 are fixedly connected to the two sides of the fixing base 41 near the bottom. Adjusting plates 43 are fixedly connected to the two sides of the fixing base 41 away from the fixing side plates 42. A sliding groove 44 is opened on the inner side of the adjusting plate 43. An extension rod 45 is slidably connected to the inner side of the sliding groove 44. A connecting base plate 46 parallel to the fixing side plate 42 is fixedly connected to the end of the extension rod 45. The relative position between the connecting base plate 46 and the fixing base 41 can be adjusted by sliding the extension rod 45, so as to adapt to different mounting bases or frames. Fixing screw holes are opened on the surfaces of the connecting base plate 46 and the fixing side plate 42, so as to securely install the entire fixing adjustment base 4 to the designated position with bolts or other fasteners.
[0028] An expansion pipe protection assembly 5 is provided on the outside of the expansion pipe 6. The expansion pipe protection assembly 5 includes a transparent protective shell 51 that is sleeved on the expansion pipe 6. The transparent protective shell 51 is made of a transparent material that is resistant to high and low temperatures. It can physically protect the pipe from accidental impact or damage and facilitate the observation of whether there are any signs of leakage in the expansion pipe 6. An infinite clamp 61 is also fixedly snapped on the surface of the expansion pipe 6 to securely connect the expansion pipe 6 to the expansion tank 1 and prevent the expansion pipe 6 from loosening. On the side of the expansion tank 1, near the expansion pipe 6, a locking rod 54 is rotatably connected. A limiting plate 52 is fixedly connected to the side of the transparent protective shell 51. A limiting groove 53 is opened on the surface of the limiting plate 52. The width of the locking rod 54 is adapted to the width of the limiting groove 53. By rotating the locking rod 54 ninety degrees, one side of it can be made to abut against the outer surface of the limiting plate 52, thereby reliably locking the transparent protective shell 51 and enhancing its stability.
[0029] A sensor base 7 is fixedly connected to the bottom of the expansion tank 1, and a sensor 8 is fixedly installed below the sensor base 7. In this embodiment, the sensor 8 is preferably a pressure sensor, and its sensing end is connected to the inside of the expansion tank 1 to continuously monitor the pressure parameters inside the expansion tank 1.
[0030] The working principle of this utility model is as follows:
[0031] An expansion pipe protection assembly 5 is installed outside the expansion pipe 6. The transparent protective shell 51 is made of transparent material that is resistant to high and low temperatures. It can not only physically protect the pipe from accidental impact or damage, but also facilitate the observation of the fluid state inside the expansion pipe 6 and whether there are any signs of leakage. The stepless clamp 61 ensures the sealing and firmness of the connection between the expansion pipe 6 and the expansion tank 1, preventing the connection point from loosening and leaking. The locking rod 54, after rotating ninety degrees, abuts against the outside of the limiting plate 52, reliably locking the transparent protective shell 51 and enhancing its stability.
[0032] Sensor 8 is fixedly installed on sensor base 7 below expansion tank 1, and its sensing end is connected to the inside of expansion tank 1 to continuously monitor the pressure parameters inside the tank.
[0033] The entire expansion tank 1 is securely installed in the energy storage system by two sets of fixing clamps 2 and the fixing adjustment base 4 below it. The extension rod 45 of the fixing adjustment base 4 can slide along the sliding groove 44 on the inner side of the adjustment plate 43, thereby adjusting the relative position between the connecting base plate 46 and the fixing base 41, so that the expansion tank can flexibly adapt to the needs of different installation environments, and is finally fixed by fixing screw holes on the fixing side plate 42 and the connecting base plate 46 to ensure its overall stability during operation.
[0034] 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.
