Description

Technical Field

[0001] The utility model relates to the technical field of closed-cycle cooling water systems, in particular to an expansion water tank for a closed-cycle cooling water system. Background Art

[0002] A closed-loop cooling water system is an efficient and environmentally friendly cooling method widely used in modern industry. A closed-loop cooling water system is a closed circuit in which cooling water circulates within the system without direct contact with the external environment. This system is primarily used to provide a stable cooling water source for various industrial equipment and units, ensuring their normal operation and temperature control. Its main components include a closed-loop cooling water pump, a closed-loop cooling water heat exchanger, and a closed-loop cooling water expansion tank. Cooling water originates from the closed-loop cooling water expansion tank, is pumped up, and then enters the heat exchanger for cooling. It then flows through the heat exchangers of various equipment to absorb heat before returning to the pump inlet, completing a closed-loop circulation. Because the system is closed, the water quality is relatively stable, free from external contamination, while also reducing water consumption and emissions.

[0003] The closed-loop cooling water expansion tank is a crucial component of the closed-loop cooling water system, primarily used to maintain system pressure stability and replenish water. It's typically installed on the water pump's inlet pipe, at the highest point in the system. Its role is to maintain pressure stability and replenish water within the closed-loop cooling water system. When the system is short of water or the system temperature drops, causing the closed-loop water to contract and pressure to drop, the expansion tank automatically replenishes water. Conversely, if the system temperature rises, the water volume expands, and the system pressure increases, the expansion tank automatically removes excess water to maintain a balanced and stable system pressure.

[0004] The expansion water tank used in a common closed-loop cooling water system is usually arranged at the highest position of the system. However, due to the influence of factors such as the site, the pre-installed bracket may not allow the expansion water tank to be at the highest position, and the height of the bracket needs to be temporarily increased, resulting in the bracket being unstable and more troublesome. In view of this, the present application proposes an expansion water tank for a closed-loop cooling water system. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides an expansion water tank for a closed-circulation cooling water system, which has advantages such as adjustable height of the expansion water tank. It solves the problem that due to factors such as the site, the pre-installed bracket may not be able to place the expansion water tank in the highest position, and the height of the bracket needs to be temporarily increased, resulting in the bracket being unstable and more troublesome.

[0006] To achieve the above object, the present invention provides the following technical solution: an expansion water tank for a closed-circulation cooling water system, comprising an expansion water tank, an adjustment base fixedly mounted on the bottom of the expansion water tank, and a limit assembly provided on the bottom of the adjustment base;

[0007] The adjustment base includes a bottom plate, four support screws are fixedly installed on the top of the bottom plate, a top plate is slidably installed on the surface of the support screws, and two adjustment nuts are threadedly installed on the surface of the support screws, and the two adjustment nuts are respectively located at the top and bottom of the top plate.

[0008] Furthermore, a through hole adapted to the support screw rods is opened on the top of the top plate, and the expansion water tank is located between the four support screw rods.

[0009] Furthermore, the limiting assembly includes four mounting vertical plates fixedly mounted on the bottom of the base plate, an adjusting screw is passed through one side of the mounting vertical plate, and a clamping vertical plate is rotatably mounted on one end of the adjusting screw.

[0010] Furthermore, a fixing nut is fixedly installed on one side of the mounting vertical plate, an adjusting screw is threadedly connected to the fixing nut, and an adjusting knob is fixedly installed on one end of the adjusting screw.

[0011] Furthermore, the tops of the bottom plate and the top plate are both provided with reserved holes, the inner bottom wall of the expansion water tank is fixedly mounted with a water collecting base, the bottom of the expansion water tank is fixedly mounted with a drain pipe, and the drain pipe is aligned with the lowest point of the water collecting base.

[0012] Furthermore, a water inlet pipe is fixedly installed on one side of the expansion water tank close to the top, and a water outlet pipe is fixedly installed on one side of the expansion water tank close to the bottom.

[0013] Furthermore, a water supply pipe and an exhaust pipe are fixedly installed on the top of the expansion water tank, an overflow pipe is fixedly installed on one side of the expansion water tank, an upper limit liquid level gauge and a lower limit liquid level gauge are fixedly installed on the inner wall of the expansion water tank, and a manhole is fixedly installed on one side of the expansion water tank.

[0014] Compared with the prior art, the present invention provides an expansion water tank for a closed-circulation cooling water system, which has the following beneficial effects:

[0015] The closed-loop cooling water system uses an expansion water tank. An adjustment base is provided at the bottom of the expansion water tank, and the adjustment base is installed on the top of an originally provided bracket. When the height of the expansion water tank is not enough, the position of the adjusting nut is adjusted to adjust the height of the top plate to raise the expansion water tank so that the expansion water tank is at an appropriate height. This solves the problem that due to factors such as the site, the bracket set in advance may not be able to put the expansion water tank at the highest position, and the height of the bracket needs to be temporarily increased, resulting in the bracket being unstable and more troublesome.
