[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in combination with the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0028] Referring to Figure 1 As shown, this embodiment proposes a gas-water separation device, including a water storage tank 1 and an exhaust valve 2, wherein:

[0029] The water storage tank 1 is provided with a water inlet 11 and a water outlet 12. The water inlet 11 is arranged at the bottom of the water storage tank 1, and the water inlet 11 is used to connect the water inlet end of the circulation pipeline. The water outlet 12 is located above the water inlet 11, and the water outlet 12 is used to externally connect a circulation pump; Liquid enters the water storage tank 1 from the water inlet 11 and forms a buffering effect inside the water storage tank 1, facilitating the discharge of gas in the liquid.

[0030] The exhaust valve 2 is arranged at the top of the water storage tank 1, and the exhaust valve 2 can be opened to exhaust when the gas pressure in the water storage tank 1 rises to reach a preset threshold.

[0031] For the gas-water separation device proposed in this embodiment, through the exhaust valve 2, it can be opened to exhaust when the gas pressure in the water storage tank 1 rises to reach a preset threshold. Liquid enters the water storage tank 1 from the water inlet 11. The gas continuously escaping from the liquid accumulates at the top of the water storage tank 1. When the gas pressure is greater than the preset threshold, the valve opening is opened and the gas is continuously discharged, avoiding problems such as the air in the circulation pipeline causing unstable water pressure and water flow, affecting the heat exchange effect, increasing the operating noise of the equipment, and causing the cavitation phenomenon of the circulation pump.

[0032] In some embodiments, the water outlet 12 is located at the lower part of the side wall of the water storage tank 1. By arranging the water outlet 12 at the lower part of the water storage tank 1, it is possible to prevent gas from being inhaled into the water outlet 12 again and entering the water cooling pipe, thereby improving the reliability and stability of the device.

[0033] In some embodiments, the exhaust valve 2 can be closed when the gas pressure in the water storage tank 1 is lower than the preset threshold. By enabling the exhaust valve 2 to be closed when the gas pressure in the water storage tank 1 is lower than the preset threshold, it is possible to avoid affecting the liquid pressure due to the exhaust valve 2 being open for a long time, thereby improving the reliability and stability of the device.

[0034] In some embodiments, the gas-water separation device further includes a water inlet pipe 3 and a water outlet pipe 4. The water inlet pipe 3 is connected to the water inlet 11, and the water outlet pipe 4 is connected to the water outlet 12. By connecting the water inlet pipe 3 to the water inlet 11 and the water inlet pipe 3 to the water inlet end of the circulating pipeline, in actual design, a flange will be connected to one end of the water inlet pipe 3 to facilitate the connection of the gas-water separation device to the circulating pipeline for convenient installation and disassembly; the water outlet pipe 4 is connected to the water outlet 12, and the water outlet pipe 4 is connected to the circulating pump. In actual design, a flange will be connected to one end of the water outlet pipe 4 to facilitate the connection of the gas-water separation device to the circulating pump for convenient installation and disassembly.

[0035] In some embodiments, the water inlet pipe 3 is a reducing pipe, and the diameter of the end of the water inlet pipe 3 far from the water inlet 11 is smaller than the diameter of the end close to the water inlet 11. By setting the diameter of the end of the water inlet pipe 3 far from the water inlet 11 to be smaller than the diameter of the end close to the water inlet 11, the flow rate of the liquid can be reduced, so that the liquid will not quickly fill the water storage tank 1, giving air a certain space to escape, thereby improving the reliability of the device.

[0036] In some embodiments, the water inlet pipe 3 is coaxial with the water storage tank 1. By making the water inlet pipe 3 coaxial with the water storage tank 1, the liquid can flow directly into the water storage tank 1, avoiding the generation of eddy currents and improving the stability of the device.

[0037] In some embodiments, the axis of the water outlet pipe 4 is perpendicular to the axis of the water storage tank 1. By setting the axis of the water outlet pipe 4 perpendicular to the axis of the water storage tank 1, this arrangement can facilitate the connection of the water outlet pipe 4 to the circulating pump and improve the convenience of installation.

[0038] In some embodiments, there are two water outlet pipes 4, and the two water outlet pipes 4 are respectively connected to two circulating pumps. By having two water outlet pipes 4 and the two water outlet pipes 4 being respectively connected to two circulating pumps, corresponding to one standby and one in use for the circulating pumps, when one circulating pump is damaged or needs maintenance, the other water outlet pipe 4 can be used to discharge water to the other circulating pump, thereby improving the reliability and stability of the device.

[0039] In some embodiments, the two water outlet pipes 4 are symmetrically arranged on both sides of the water storage tank 1. By symmetrically arranging the two water outlet pipes 4 on both sides of the water storage tank 1, when the two water outlet pipes 4 discharge water, the flow pressures of the liquid cancel each other out, avoiding the generation of eddy currents in the water storage tank 1 and improving the reliability and stability of the device.

[0040] In some embodiments, the exhaust valve 2 adopts an AEVS type automatic exhaust valve. The AEVS type automatic exhaust valve has the following advantages: (1) Reliable performance: The exhaust mechanism of the exhaust valve 2 is very reliable. Each valve has passed the exhaust experiment and pressure seal experiment before leaving the factory; (2) Convenient maintenance: A cut-off valve (optional) is installed in front of the exhaust valve 2. The cut-off valve allows the exhaust valve 2 to be conveniently removed from the system for maintenance, and the water in the system will not flow out, so there is no need to empty or shut down the system; (3) Only exhausts air and does not drain water. The steam-water separation design adopts a special structure to ensure that there is absolutely no water leakage during exhaust; (4) The parts are made of stainless steel SS304, which is not easy to corrode and is durable, suitable for high temperatures up to 200°C; (5) The polymer material floating ball is light in weight, high temperature resistant, corrosion resistant, and has good exhaust effect. Based on the above advantages of the AEVS type automatic exhaust valve, the exhaust valve 2 in this embodiment preferably adopts the AEVS type automatic exhaust valve.

[0041] The working principle of this gas-water separation device is as follows: The liquid enters the water storage tank 1 from the water inlet 11, forms a buffering effect in the water storage tank 1, which is convenient for the discharge of the gas in the liquid. The gas continuously escaping from the liquid accumulates at the top of the water storage tank 1. When the gas pressure is greater than the preset threshold, the valve port opens, and the gas is continuously discharged, avoiding problems such as the air in the circulation pipeline causing unstable water pressure and water flow, affecting the heat exchange effect, increasing the operating noise of the equipment, and causing the cavitation phenomenon of the circulation pump; when the gas pressure in the water storage tank 1 is lower than the preset threshold, the valve port of the exhaust valve 2 closes, avoiding affecting the liquid pressure due to the long-term opening of the exhaust valve 2 and improving the reliability and stability of the device.

[0042] The above is only the preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
