Description

Technical Field

[0001] The utility model belongs to the technical fields of HVAC systems, water treatment systems and other closed water systems in manufacturing, commercial office buildings, etc., and particularly relates to a closed water system tube-type centralized exhaust and drainage integrated device. Background Art

[0002] A closed water system provides a cooling water source for each auxiliary equipment of a unit (including bearing cooling water for some rotating equipment) to ensure the normal operation of the auxiliary equipment and the system. When applied to industrial and civil buildings, it generally needs to be dispersed. The air-conditioning chilled water closed system in an integrated circuit chip manufacturing plant and the large commercial closed water system have quite large capacities. In the initial stage of system establishment, the exhaust and drainage systems of the huge system are indispensable for intermediate commissioning tests and later maintenance operations. Arranging too many dispersed points is not conducive to system management and maintenance, mainly manifested as follows: 1. The troubleshooting time is long when problems occur. The dispersed small-capacity exhaust valves are prone to blockage and leakage hazards, which is not conducive to system stability; 2. It may cause fluctuations in system temperature and pressure, affecting the temperature and pressure fluctuations in important production areas and thus affecting production accuracy, and even causing the appearance of defective products; 3. If serious problems occur and the pressure is not drained in time, it will cause greater losses. In this case, too many dispersed drainage points are also not conducive to system management and maintenance. Content of the Utility Model

[0019] See Figure 1 and Figure 2 As shown, in the preferred embodiment, the closed - type water system tube - type integrated gas - exhausting and water - draining device of the present utility model is used to discharge the gas (such as air, air bubbles and other non - chilled - water components) generated in the closed - type water system from the pipeline system. Specifically, it includes a water - collecting and gas - collecting main pipeline 1, a three - way valve 2, a vacuum - breaking valve 3, a large - capacity exhaust valve 4, a drain valve group 5 and several exhaust - partition branch pipelines 6. The water - collecting and gas - collecting main pipeline 1 is horizontally arranged transversely. The water - collecting and gas - collecting main pipeline 1 is connected to the system exhaust point through the exhaust - partition branch pipelines 6. The exhaust - partition branch pipelines 6 include branch - partition valves 7. The water - collecting and gas - collecting main pipeline 1 is connected to the drainage system through the drain valve group 5. The water - collecting and gas - collecting main pipeline 1 is respectively connected to the vacuum - breaking valve 3 and the large - capacity exhaust valve 4 through the three - way valve 2. The large - capacity exhaust valve 4 is installed on the exhaust pipeline of the integrated gas - exhausting and water - draining device, and is used to control the discharge of gas. The vacuum - breaking valve 3 can ensure the smooth drainage of the system and protect the system from being damaged by vacuum, so as to make the drainage smooth and not affect the drainage speed and the pipeline due to vacuum reasons.

[0020] Gas - collecting pipe end - caps 8 are fixed at both ends of the water - collecting and gas - collecting main pipeline 1. It is easy to understand that the exhaust pipeline provided with an exhaust valve is connected to the high point of the chilled - water pipeline system or the highest point of this area to collect and discharge gas. The gas from multiple exhaust pipelines of the whole system can be concentrated in this device, which is convenient for maintenance and exhaust treatment. At the same time, the drain pipeline provided with a drain valve is connected to the low point of the chilled - water pipeline system or the lowest point of this area to collect and discharge water. The centralized drainage of the system is convenient for making controllable drainage in case the system needs to be drained due to faults, and reducing the fault losses. The three - way valve 2, the branch - partition valve 7 and the drain valve group 5 can be manually switched to the exhaust or drainage state.

[0021] A temperature - pressure gauge 9 is connected to the water - collecting and gas - collecting main pipeline 1. The temperature - pressure gauge 9 has the function of local display and remote transmission, and can transmit the pressure and temperature of the centralized device to the FMCS system in the duty room online. The duty room can understand the current state of this device at any time and is always in the online monitoring state, which is beneficial to operation and maintenance management.

[0022] There are preferably four exhaust zoning branches 6, and the exhaust zoning branches 6 and the drain valve group 5 are connected by transparent pipes, through which the state of the medium can be clearly seen.

[0023] A support leg 10 is provided at the bottom of the water and gas collecting main pipeline 1. Further, the support leg 10 includes an upper leg portion and a lower leg portion, the upper leg portion is a vertically arranged "T" shape, and the lower leg portion is a horizontally arranged "I" shape, which improves the support stability.

[0024] This centralized venting and draining helps maintain the normal operation of the piping system, ensuring that gases and moisture do not negatively impact system performance.

[0025] The above are only preferred embodiments of the present invention, and do not limit the implementation mode and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
