Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic control of a high-efficiency machine room, in particular to a water flow control device suitable for a high-efficiency machine room. Background Art

[0002] In the operation and maintenance of modern data centers and high-efficiency computer rooms, the stability and efficiency of the liquid supply system (water pressure pump) is one of the key factors to ensure the normal operation of the equipment. Traditional liquid management systems, especially when dealing with high-pressure liquid supply, often face the problem of large fluctuations and uneven distribution of liquid pressure, which affects the heat exchange efficiency of the equipment. Especially in large computer rooms, due to the different lengths of liquid pipelines and complex pipeline layouts, it is often difficult to maintain consistent liquid pressure from the water supply source to each terminal device, especially in the latter part of the system. The pressure loss is often significant, resulting in the liquid supply pressure being much lower than the front section, affecting the stability and efficiency of the overall system.

[0003] To address this problem, traditional solutions rely on installing multiple pressure regulating valves and complex control systems to adjust the pressure locally, but this not only increases the complexity and maintenance cost of the system, but may also cause more unstable factors due to improper local adjustment. In addition, frequent maintenance and calibration work is also a considerable burden, especially in the modern and efficient machine room environment that pursues high automation and low maintenance costs.

[0022] 3. Beneficial Effects

[0023] Compared with the prior art, the utility model has the following beneficial effects:

[0024] The utility model is sealed at the drainage end by the core head. When high-pressure liquid (hot water or cold water) flows into the water inlet joint, the hydraulic pressure in the outer tube increases. Since the airway is connected to the outside, it is always maintained at the standard large hydraulic pressure. The liquid in the outer tube pushes the piston into the sliding column cavity, and the piston drives the connecting rod and the core head to move. The core head is separated from the drainage end, the spring is compressed, and the liquid is discharged from the drainage end. The hydraulic pressure in the outer tube decreases, and the spring extends to drive the core head to seal at the drainage end. After the drainage end is blocked, the hydraulic pressure in the outer tube increases again, and the flow rate of liquid discharged from the drainage end is maintained stable in dynamic balance, forming an efficient feedback regulation system, thereby ensuring that the pressure of liquid discharged from the device connected at multiple different positions of the water supply main pipeline in the high-efficiency machine room is balanced, and the pressure loss will not cause the output liquid pressure of the rear section of the main pipeline to be much smaller than that of the front section, thereby maintaining the heat exchange of the stable pressure water channel of the overall system.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0030] A water flow control device suitable for high-efficiency machine rooms, see Figure 1-3 , including an outer tube 1, an adjusting member 4 and a movable core 5. The outer tube 1 is hollow inside and has a plugging end 11 and a drainage end 12, wherein the plugging end 11 is connected with a tail plunger 3, and the tail plunger 3 is used to isolate the internal and external liquid circulation of the plugging end 11 of the outer tube 1. The drainage end 12 is connected to an external liquid nozzle or pipeline to output liquid at a stable pressure to ensure the stable circulation of liquid (cold and hot water for exchanging heat) in the high-efficiency machine room.

[0031] A water inlet joint 2 is provided on the side wall of the outer tube 1. The water inlet joint 2 is communicated with the inside of the outer tube 1. The water inlet joint 2 is connected to the main water pipeline for distributing and transporting high-pressure liquid. A plurality of water inlet joints 2 are connected to different positions of the main water pipeline, and balanced water delivery is achieved through a plurality of liquid pressure-stabilizing circulation control devices, which can ensure that the pressure of the liquid discharged from a plurality of different positions in the high-efficiency machine room is balanced, and the output liquid pressure of the rear section of the main pipeline will not be much lower than that of the front section due to pressure loss.

[0032] The adjusting member 4 at least includes a receiving section 41, a connecting section 42 and an extending section 43 connected in sequence, and the movable core 5 at least includes a core head 51, a connecting rod 52 and a piston 53 connected to the end of the connecting rod 52, wherein the core head 51 is spherical, and the inner surface of the outer tube 1 of the drainage end 12 is an arc surface, and the core head 51 can be embedded with the inner surface of the drainage end 12 to block the drainage end 12;

[0033] The connecting section 42 is located between the water inlet joint 2 and the drainage end 12. The connecting section 42 is basically cylindrical with an external thread on the outer surface. The external thread on the outer surface of the connecting section 42 is threadedly connected with the internal thread on the inner wall of the outer tube 1. Through the threaded connection, the connecting section 42 is fixed to the inner part of the outer tube 1. A flow groove 421 is formed through the surface of the connecting section 42. The flow groove 421 allows liquid to flow from the side of the water inlet joint 2 to the drainage end 12.

[0034] The end surface of the receiving section 41 is provided with a sliding column cavity 411 along the axial direction, and the piston 53 is slidably connected with the sliding column cavity 411;

[0035] The extension section 43 has an air passage 431 in communication with the sliding column cavity 411. The end surface of the tail plunger 3 is provided with a through hole 31 in the axial direction. The extension section 43 is slidably connected with the through hole 31 in a watertight manner. The extension section 43 passes through the through hole 31 and extends to the outside of the outer tube 1. A plurality of sealing rings 8 are provided on the outer wall of the extension section 43 to maintain the watertightness at the through hole 31. In addition, the extension section 43 can also maintain the watertightness by high-precision clearance fit with the through hole 31.

[0036] A spring 6 is sleeved on the outside of the connecting rod 52 , and two ends of the spring 6 respectively abut against the core head 51 and the end surface of the connecting section 42 .

[0037] Working principle: When in use, high-pressure liquid enters the outer tube 1 from the water inlet joint 2, and the liquid flows to the drainage end 12 through the circulation groove 421. The core head 51 is blocked at the drainage end 12 to increase the hydraulic pressure in the outer tube 1. At this time, the airway 431 is always maintained at the standard large hydraulic pressure due to its connection with the outside. The liquid in the outer tube 1 pushes the piston 53 into the sliding column cavity 411, and the piston 53 drives the connecting rod 52 and the core head 51 to move. The core head 51 is separated from the drainage end 12, the spring 6 is compressed, and the liquid is discharged from the drainage end 12. The hydraulic pressure in the outer tube 1 is reduced, and the spring 6 is extended to drive the core head 51 to block the drainage end 12. After the drainage end 12 is blocked, the hydraulic pressure in the outer tube 1 increases again, and the flow rate of liquid discharged from the drainage end 12 is maintained stable in dynamic balance.

[0038] This device uses the pressure difference between the outer tube 1 and the airway 431 to drive the reciprocating motion of the piston 53 and the core head 51, thereby automatically adjusting the drainage volume and ensuring that the liquid pressure in the outer tube is stable within the set range. Even when faced with complex machine room pipeline layouts and different water demands, it can effectively avoid the problem of unbalanced water supply caused by pressure loss. Since the working principle of this device is based on a simple physical mechanism, there is no need for a complex electronic control unit, which not only reduces the number of failure points, but also simplifies the installation and maintenance process. The linkage design of the piston 53 and the core head 51, combined with the elastic effect of the spring 6, forms an efficient feedback adjustment system, which can respond quickly at the moment of liquid pressure increase and automatically start drainage, and when the pressure drops to an appropriate range, it can automatically block to ensure stable output of liquid. This device not only improves the reliability of liquid supply, but also significantly improves the economy and safety of machine room operations.

[0039] In addition, a knob 7 is fixedly provided at the end of the extension section 43. The knob 7 can be set to be detachable to facilitate assembly. Turning the knob 7 drives the adjusting member 4 to rotate as a whole. Since the connecting section 42 cooperates with the inner wall thread of the outer tube 1, the adjusting member 4 moves axially as a whole, thereby changing the initial compression amount of the spring 6, adjusting the pressure value required for the core head 51 to disengage from the drainage end 12, and changing the dynamic balance pressure responded by the core head 51.

[0040] As an embodiment of the utility model, the air channel 431 is enlarged near the sliding column cavity 411 to form a square inner cavity 4311, and a short rod 54 is fixed to the end face of the piston 53, and a limiting head 55 is fixed to the end of the short rod 54. The limiting head 55 can abut against the end of the square inner cavity 4311 to limit the maximum movement of the movable core 5 toward the drainage end 12, thereby preventing the piston 53 from moving out of the sliding column cavity 411 during initial assembly.

[0041] In this embodiment, the tail plunger 3 is a rubber plug, which is threadedly connected to the blocking end 11. A knob 7 is fixedly provided at the end of the tail plunger 3. The knob 7 can be turned to move the tail plunger 3 upward along the axis of the outer tube 1 to change the entry depth. When the tail plunger 3 is screwed in, the side of the tail plunger 3 gradually blocks the communication port between the water inlet joint 2 and the outer tube 1, thereby reducing the liquid flow rate entering the outer tube 1. When the tail plunger 3 is screwed out, the side of the tail plunger 3 gradually separates from the communication port between the water inlet joint 2 and the outer tube 1, thereby increasing the liquid flow rate entering the outer tube 1. Therefore, by rotating the tail plunger 3, the water flow area at the connection between the water inlet joint 2 and the outer tube 1 can be adjusted to change the liquid flow rate, and finally the liquid discharge amount of the drainage end 12 can be controlled.

[0042] In addition, an outer chamfer 32 is provided at the end edge of the tail plug 3, and the inner wall of the outer tube 1 above the water inlet joint 2 is stepped and provided with an inner chamfer 13. When the tail plug is fully screwed in, the outer chamfer 32 fits with the inner chamfer 13 to cut off the flow of liquid from the water inlet joint 2 to the discharge end 12.

[0043] The above-described embodiments are merely descriptions of preferred implementations of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by ordinary personnel in the field to the technical solution of the present invention should fall within the protection scope of the present invention, and the technical contents of the present invention for protection have been fully recorded in the claims.
