Description

Technical Field

[0001] This utility model relates to the field of spray pipes, specifically a spray pipe with switchable width. Background Technology

[0002] The primary function of sprinkler pipes is to transport cooling water. In many cooling scenarios, such as industrial equipment cooling and sprinkler cooling in fire protection systems, water is a commonly used and effective cooling medium. Water is transported through pipes to various parts of the sprinkler pipes, and then evenly sprayed out from the nozzles to cool the target object or area. For example, in the containment sprinkler system of a nuclear power plant, during a loss-of-coolant accident, water pipes transport boron-containing water to the sprinkler pipes, which is then sprayed into the containment through nozzles to reduce the peak pressure and temperature inside the containment. Utilizing the high specific heat capacity of water, when hot water meets the cooled object... When water comes into contact with an object or a high-temperature environment, it absorbs heat, causing the temperature of the object or environment to decrease while its own temperature increases, thus achieving heat transfer and cooling. Simultaneously, water absorbs a large amount of heat of vaporization during evaporation, further enhancing the cooling effect. The cooling spray pipe is equipped with multiple nozzles, through which water is sprayed at a specific angle and pressure, forming fine droplets or mist that directly cover the surface of the object to be cooled. For example, in metal processing, direct spray cooling of high-temperature metal workpieces can quickly reduce the workpiece temperature, improving its performance and processing accuracy.

[0003] Different cooling scenarios have different requirements for the spray coverage. If the spray width is fixed and cannot be adjusted, it is difficult to accurately and evenly cover the target area with the cooling medium. For example, in the cooling of large industrial equipment, different parts of the equipment have different heat distributions. The spray width needs to be adjusted according to the actual heat distribution to ensure uniform cooling. If it cannot be switched and adjusted, some parts may be over-cooled while other parts are under-cooled, wasting a lot of water resources. Utility Model Content

[0004] The purpose of this invention is to provide a spray pipe with switchable width to solve the defects mentioned in the background art.

[0005] To achieve the above objectives, a switchable spray pipe is provided, comprising a spray pipe body, a connecting piece installed at the right end of the spray pipe body, and an end seat fixedly provided on the surface of the connecting piece; a water pipe and an air pipe are respectively inserted inside the spray pipe body, a cold water branch pipe A is provided on one side of the water pipe and the air pipe, a cold water branch pipe B is installed at the bottom of the cold water branch pipe A, and a nozzle mounting seat is fixedly provided on the spray pipe body, the interior of the nozzle mounting seat being connected to the inner cavity of the spray pipe body.

[0006] Preferably, the water inlet position at the left end of the water pipe is L-shaped, and the air inlet position at the left end of the air pipe is straight, with the inner diameters of the water pipe and the air pipe being the same.

[0007] Preferably, a flange is fixedly installed on the outer wall of the left circumference of the spray pipe body, and multiple sets of equally spaced bolt holes are evenly opened on the flange; the flange is installed on the side of the spray pipe body near the water pipe and air pipe.

[0008] Preferably, eight sets of nozzle mounting seats are evenly installed on the spray pipe body. The nozzle mounting seats are rectangular and the distance between adjacent sets of nozzle mounting seats is the same.

[0009] Preferably, the nozzle mounting base has two sets of mounting holes evenly spaced, and a spray head is screwed onto each of the two sets of mounting holes.

[0010] Preferably, the right end of the spray pipe body is fixedly connected to the connecting piece by multiple sets of reinforcing plates, and the reinforcing plates are right-angled trapezoidal structures made of metal.

[0011] Preferably, the inner diameters of the cold water branch pipe A and the cold water branch pipe B are the same, and the water inlet parts at the ends of the cold water branch pipe A and the cold water branch pipe B are both inclined.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model uses airflow mixed with water flow to allow compressed air to be used as an auxiliary cooling medium. The air pipe delivers air to the vicinity of the spray pipe body or mixes it with water before spraying it out. The combination of air and water can enhance the cooling effect; air can promote the evaporation of water, and water absorbs heat when it evaporates, thereby improving the cooling efficiency; the air introduced through the air pipe can, to a certain extent, prevent blockage inside the spray pipe body and inside the nozzle.

[0014] 2. This utility model allows valves to be installed at the inlets of cold water branch pipes A and B. By adjusting the water flow velocities of cold water branch pipes A and B, different degrees of momentum exchange occur, enabling the switching and adjustment of the water pressure of the main water flow. This, in turn, affects the spray speed and direction of the main water flow, thus adjusting the spray area. When the cold water velocity in the branch pipes is greater than the main water flow velocity, the main water flow accelerates and changes direction at the mixing point, expanding the spray area; conversely, the same applies. The spray area of ​​the spray pipe body can be adjusted according to the shape, size, and heat-generating parts of the object being cooled, allowing the cooling medium to be concentrated on the area requiring cooling, achieving precise cooling and conserving water resources.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 This utility model provides a spray pipe with switchable width, including a spray pipe body 6, a connecting piece 9 installed at the right end of the spray pipe body 6, and an end seat 10 fixedly installed on the surface of the connecting piece 9; a water pipe 1 and an air pipe 2 are respectively inserted inside the spray pipe body 6, a cold water branch pipe A3 is provided on one side of the water pipe 1 and the air pipe 2, a cold water branch pipe B4 is installed at the bottom of the cold water branch pipe A3, and a nozzle mounting seat 7 is fixedly installed on the spray pipe body 6, and the interior of the nozzle mounting seat 7 is connected to the inner cavity of the spray pipe body 6.

[0024] Working Principle: In actual use, the spray pipe body 6 is fixedly installed near the equipment requiring cooling via flange 5. During spraying, water and air flow enter the interior of water pipe 1 and air pipe 2 respectively, and are sprayed out from the nozzles mounted on the eight-head mounting base 7. The water flow is mixed with air flow, allowing compressed air to serve as an auxiliary cooling medium. The air pipe delivers air to the vicinity of the spray pipe body 6 or mixes it with water before spraying it out. The combination of air and water enhances the cooling effect. Air promotes water evaporation, and water absorbs heat during evaporation, thereby improving cooling efficiency. The air introduced through air pipe 2 can... To a certain extent, it prevents internal blockage of the spray pipe body 6 and the nozzle from becoming clogged. Especially in systems with poor water quality or where impurities are prone to sedimentation, the airflow can agitate the water flow, reducing the deposition and agglomeration of impurities in the pipes and keeping the pipes unobstructed. In addition, for situations where pipe blockage may occur due to freezing, introducing warm air can play a role in preventing freezing. The air pipe can also be used to balance the pressure within the spray pipe body 6 system. When the water flow rate in the system changes or local resistance occurs, adjusting the air flow rate in the air pipe can adjust the pressure distribution of the system, ensuring that the spray pipe body 6 can spray water evenly.

[0025] Cold water branch pipes A3 and B4 are also installed on the main body of the spray pipe 6. When external cold water enters the main water flow inside the spray pipe body 6 from the cold water branch pipes A3 and B4, it will generate a lateral force on the main water flow, causing the spray direction of the main water flow to change, thereby adjusting the spray width. The cold water branch pipes A3 and B4 are set to tilt towards one side of the main water flow of the spray pipe body 6, so that the main water flow deflects to that side and expands the spray range on that side. Valves can be installed at the inlets of cold water branch pipes A3 and B4. The flow rate of the cold water can be controlled by adjusting the valve opening on these pipes. When the cold water velocity in the branch pipes differs from the flow rate in the main spray pipe 6, varying degrees of momentum exchange occur, regulating the water pressure of the main flow and thus affecting the spray speed and direction, thereby adjusting the spray width. When the cold water velocity in the branch pipes is greater than the flow rate in the main spray pipe, it will cause the main... The water flow accelerates and changes direction at the mixing point, expanding the spray area; conversely, if the cold water velocity in the branch pipe is less than the main water flow velocity, the main water flow will decelerate, reducing the spray area. The spray area of ​​the spray pipe body 6 can be adjusted according to the shape, size, and heat-generating parts of the object being cooled, allowing the cooling medium to be concentrated on the area requiring cooling for precise cooling. Cooling requirements may change under different working scenarios and process conditions; the spray pipe body 6 with adjustable spray area can quickly adapt to these changes. In industrial production, when changes in product specifications or production processes lead to different heat generation conditions, the new cooling requirements can be met by adjusting the spray area, eliminating the need to redesign and reinstall the spray system, saving time and costs. By controlling the spray area, the cooling medium can be accurately sprayed onto the target area, reducing the amount of cooling medium sprayed onto areas that do not need cooling, thus avoiding waste of water resources or other cooling media.

[0028] As a preferred embodiment, eight sets of nozzle mounting seats 7 are evenly installed on the spray pipe body 6. The nozzle mounting seats 7 are rectangular and the distance between adjacent sets of nozzle mounting seats 7 is the same.

[0029] As a preferred embodiment, the nozzle mounting base 7 is provided with two sets of mounting holes 71 evenly spaced, and a spray head is screwed onto each of the two sets of mounting holes 71.

[0031] As a preferred implementation, the inner diameters of cold water branch pipe A3 and cold water branch pipe B4 are the same, and the water inlet parts at the ends of cold water branch pipe A3 and cold water branch pipe B4 are both inclined.

[0032] Eight sets of nozzle mounting seats 7 are evenly installed on the spray pipe body 6, forming eight spray areas to achieve uniform cooling. The flow rate of the medium inside the water pipe 1 and air pipe 2 can be automatically adjusted according to the actual measured temperature of the inlet plate thermometer of the cooling section to achieve automatic adjustment of the cooling rate.
