Example Embodiment

[0016] Implementation mode 1:

[0017] Generally, the expansion tank is set at the highest point of the system. Therefore, the expansion tank in this embodiment is not equipped with nitrogen, so that the storage capacity of pure water in the expansion tank becomes larger, and the system can be supplemented by the gravity of the water. The liquid level pressure stabilization device of the expansion tank in the closed cycle water cooling system of this embodiment is as figure 1 Shown. A funnel-shaped container 5 is installed on the upper part of the expansion tank 6, and the top of the funnel-shaped container 5 is a sealing cover 4. The funnel-shaped container 5 and the expansion tank 6 are welded together. The expansion tank 6 is equipped with a float, and the structure of the bottom 12 of the float is as figure 2 As shown, this structure is to enable the float to float on the water well. The inner wall of the expansion tank 6 has a slideway suitable for the cross structure, an...

Example Embodiment

[0020] Implementation mode 2:

[0021] See image 3 On the basis of Embodiment 1, there is no float inside the expansion tank 6, and there is no slide on the inner wall of the expansion tank 6, that is, no float structure is adopted. An electric valve 15 is installed at the connecting pipe between the funnel-shaped container 5 and the expansion tank 6. In the initial water injection of the closed cycle water cooling system, the electric valve 15 is opened, and when the water volume in the expansion tank 6 reaches the maximum liquid level pressure allowed (set) by the system, the electric valve 15 is closed. During the operation of the closed-cycle water-cooling system, when the liquid level pressure of the expansion tank 6 is lower than the minimum liquid level pressure allowed by the system, the electric valve 15 is opened, and when the water volume in the expansion tank 6 reaches the system allowed (set) When the liquid level pressure is at its maximum, the electric valve 15 ...

Abstract

The invention aims to provide an expansion tank liquid level pressure stabilization system in a closed water-cooling circulating system. The expansion liquid level pressure stabilization system comprises an expansion tank, an outer water replenishing pipeline, an internal water replenishing pipeline and a container which is a funneled container; a sealing cover is arranged on the funneled container; the outer water replenishing pipeline is connected with the funneled container and the internal water replenishing pipeline respectively; the funneled container is connected with the expansion tank which is connected with a main water pipeline and an auxiliary pipeline respectively; and the auxiliary pipeline is connected with a small water storage tank which is communicated with the internal water replenishing pipeline. The equipment of the conventional nitrogen pressure stabilization system is reduced, the expansion tank pressure stabilization system in the closed water-cooling system is simplified, the problem of small change range and unstability of the expansion tank liquid level pressure is solved, the closed water-cooling system does not stop when the condition of environment is changed, and the reliability of long-term running of the closed water-cooling system is improved.

Description

technical field [0001] The invention relates to a pressure stabilizing device for a water-cooling circulation system. Background technique [0002] The expansion tank is an indispensable device in the closed water cooling cycle system, and its function is to accommodate and compensate the expansion and contraction of water in the cooling system. The expansion tank is generally filled with high-purity nitrogen. When a small amount of pure water seeps out or is lost in electrolysis, the nitrogen expands automatically and presses the pure water into the circulating pipeline system to keep the pipeline pressure constant and full of water. Due to the presence of nitrogen, the storage capacity of the expansion tank is even less. If there is air leakage from the connecting pipe or joint, nitrogen should be supplied to the expansion tank in time. For the application number 01247045.7, the name is "automatic air replenishment and water supply device for bladder expansion water tank...
