[0026] Embodiment 1

[0027] At present, the pipeline exhaust in the traditional method of data center is equipped with an automatic exhaust valve 1 at the highest point, and the air is slowly discharged by normal low frequency operation of the water pump, or the operation and maintenance personnel climb to the highest point to operate, which not only increases the operation difficulty, but also has the safety risk of high-altitude operation, affects the work efficiency and safety. The present embodiment provides a kind of data center chilled water system exhaust device, such asFigure 1 As shown, it comprises an automatic exhaust valve 1 and a first ball valve 2 connected by a pipeline, the first ball valve 2 is located at the highest point of the chilled water pipe 7, and the air in the fluid passes through the first ball valve 2 and is exhausted through the automatic exhaust valve 1 when the system is running; a three-way valve 3 is arranged between the first ball valve 2 and the exhaust valve, and the reversing port of the three-way valve 3 is connected with a second ball valve 4 through a pipeline, and the second ball valve 4 leads to a floor drain 6.

[0028] In the current data center traditional practice, the pipeline exhaust is all equipped with an automatic exhaust valve 1 at the highest point, which cannot quickly exhaust the air in the pipeline, seriously affecting the stable operation of the system, and cavitation will cause unnecessary damage to the pipeline and equipment; the operation and maintenance personnel need to climb to the highest point for operation, which not only increases the operation difficulty, but also has the safety risk of high-altitude operation, affecting the work efficiency and safety.

[0029] The reasons for the above shortcomings are as follows:

[0030] 1. The air cannot be quickly exhausted, and the high-speed operation of the water pump will bring the air into the equipment;

[0031] 2. The exhaust valve has limited exhaust capacity and cannot achieve rapid exhaust;

[0032] 3. The exhaust valve is prone to failure, causing the gas to be unable to be discharged in time;

[0033] 4. The exhaust valve is designed at the top of the pipeline, which requires the operation and maintenance personnel to perform high-altitude operation for exhaust.

[0034] The automatic exhaust device of the embodiment mainly comprises two ball valves, an automatic exhaust valve 1 and a pipeline, the first ball valve 2 is connected to the highest point of the chilled water pipe 7, a three-way valve 3 is arranged in the middle, the automatic exhaust valve 1 is connected to the upper part, and the second ball valve 4 is installed on the side and leads to the floor drain 6, which is used to exhaust the water in the pipeline into the floor drain 6.

[0035] The two ball valves are respectively installed at specific positions of the pipeline and play a role in controlling the on-off of the fluid. They can quickly cut off the fluid flow during device installation, maintenance and abnormal conditions, facilitating operation and maintenance. The ball valve has the characteristics of good sealing, flexible operation and high reliability, and can ensure effective control of the fluid under different working conditions.

[0036] The main function of the automatic exhaust valve 1 is to automatically exhaust the air accumulated in the pipeline during system operation. When there is air in the pipeline, the automatic exhaust valve 1 can sense the presence of gas and open the valve under the action of pressure to exhaust the air out of the pipeline. Once the air is exhausted, the valve will automatically close to prevent fluid leakage. The sensitivity and reliability of the automatic exhaust valve 1 are crucial to the performance of the device, which can effectively remove the air in time to ensure the normal operation of the system.

[0037] When the system starts running, fluid flows through the pipeline. If there is air in the pipeline, the air will gradually accumulate at a high point or a specific location under the push of the fluid. The automatic air vent valve 1 is installed at the high point of the pipeline or the location where air is easy to accumulate. When the air accumulates to a certain extent, the pressure sensor inside the automatic air vent valve 1 senses the change of the gas pressure. Once the pressure reaches the set value, the automatic air vent valve 1 will automatically open to discharge the air out of the pipeline. With the discharge of the air, the fluid pressure in the pipeline gradually returns to normal, and the automatic air vent valve 1 will automatically close under the action of spring force or other reset mechanisms. The two ball valves can be manually operated when needed to control the on-off of the fluid. For example, during the installation, commissioning or maintenance of the device, the ball valve can be closed to cut off the fluid flow and ensure the safety of the operation.

[0038] When the chilled water system leaks air, in addition to the automatic air venting of the automatic air vent valve 1, manual rapid emergency air venting can be performed through the second ball valve 4. Daily, monthly and quarterly maintenance can also check whether there is air in the pipeline and whether the automatic air vent valve 1 is working normally through the second ball valve 4.

[0039] The pipeline at the lower end of the first ball valve 2 is connected to the highest point of the heating and ventilation water system pipeline and is always open, and a three-way valve 3 is connected in the middle, which is connected to the second ball valve 4 and the automatic air vent valve 1, and the second ball valve 4 is connected to the floor drain 6 and is always closed. When the system is running, the air in the water passes through the first ball valve 2 and is discharged through the automatic air vent valve 1. In an emergency, the second ball valve 4 only needs to be opened to achieve rapid air venting, which can also reduce the climbing operation of the operation and maintenance personnel and prevent safety accidents.

[0040] In summary, the original technology is automatically vented through the air vent valve, but the water in the running system is in a flowing state, the effect of the air vent valve is poor, and most of the air will remain in the pipe; the maintenance personnel need to climb and manually vent at a high place.

[0041] In the utility model scheme, the ball valve, the three-way valve 3 and the air vent pipe are added, and the floor drain 6 is introduced, which can manually vent when the system is running to discharge more gas in the pipe, and also can open the manual air vent valve to vent when the system is stationary, which can maximize the air discharge from the pipeline without entering the equipment, thereby avoiding affecting the normal operation of the equipment and reducing the risk of personnel climbing operation.

[0042] Further, in order to facilitate operation, the second ball valve 4 of the embodiment is less than 230 cm from the ground, so that the operator only needs to stand on the ground to operate the second ball valve 4 to discharge the gas in the pipeline or to operate the on-off of the fluid, without climbing, avoiding the risk and time consumption caused by climbing. Further, the pipeline connecting the second ball valve 4 and the three-way valve 3 is a right-angle pipeline 5, including a horizontal pipeline and a vertical pipeline, so as to conveniently introduce the fluid or gas of the three-way valve 3 connected on the highest pipeline to the ground, and save space, and the pipeline layout is simple.

[0043] Finally, it should be pointed out that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit it. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part of the technical features, and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
