Description

Technical Field

[0001] The utility model belongs to the technical field of industrial circulating water treatment equipment, and specifically relates to an adjustable temporary high-pressure fire-fighting water supply device. Background Art

[0002] With the acceleration of urbanization and the improvement of fire prevention awareness, temporary high-pressure fire water supply systems are increasingly used in various buildings and places. These systems usually include water tanks, water pipes, high-pressure sprinklers, and related control valves and water pumps to provide the high-pressure water flow required for fire extinguishing.

[0003] However, in actual use, temporary high-pressure fire water supply systems may face some problems. One of the important problems is the accumulation of impurities inside the water pipe. Since water is stored in the water tank for a long time and may carry impurities such as sediment, suspended matter, rust, microorganisms, etc. when flowing in the pipe, the accumulation of these impurities may affect the normal operation of the water supply system.

[0004] The presence of impurities may cause the following problems: First, they may clog key components such as water pumps, control valves and nozzles, hindering the normal flow of water and thus affecting the fire extinguishing effect. Second, impurities may also cause corrosion and damage to the inner wall of the water pipe, shortening the service life of the system. In addition, clogged nozzles may cause unstable water flow, affecting the efficiency and reliability of fire extinguishing.

[0005] In order to solve these problems, the inside of the water pipe needs to be cleaned regularly to remove the accumulated impurities. Traditional cleaning methods may require dismantling the pipe or using complex cleaning equipment, which is not only cumbersome to operate, but may also affect the normal operation of the system. Therefore, a more convenient and efficient method is needed to clean the impurities inside the water pipe to ensure the reliability and stability of the system.

[0006] To this end, we proposed an adjustable temporary high-pressure fire water supply device, which can clean the impurities inside the water pipe, thereby preventing the water pipe and the nozzle from being blocked, thereby stabilizing the water spray and indirectly improving safety. Utility Model Content

[0010] The water conduit is provided with a water pump, a first flow control valve, a debris removal component, a second flow control valve, a pressure stabilizing valve, a third flow control valve, a fourth flow control valve, a first conduit and a second conduit in sequence from left to right, one end of the first conduit is located between the first flow control valve and the second flow control valve, the other end of the first conduit is arranged between the third flow control valve and the fourth flow control valve, one end of the second conduit is located between the third flow control valve and the fourth flow control valve, and the other end of the second conduit is communicated with the debris removal component;

[0011] The impurity removal component comprises a connecting shell connected with the second conduit and the water conduit, a moving component is arranged inside the connecting shell, and an impurity remover is arranged on the moving component, and the impurity remover is composed of a sphere and a circular scraper.

[0012] Furthermore, a filter housing located inside the water tank is provided at one end of the water conduit.

[0013] Furthermore, the diameters of the first conduit, the second conduit and the water conduit are the same as the diameter of the impurity remover.

[0015] Furthermore, a fifth control valve is provided on the first conduit and the second conduit.

[0016] Furthermore, the water conduit is also provided with a pressure gauge.

[0017] The technical effects achieved by this utility model are:

[0018] First, open the first flow control valve, the second flow control valve, the third flow control valve and the fourth flow control valve, and start the water pump so that the water inside the water tank enters the water pipe. The water inside the water pipe is regulated by the pressure regulating valve, and then sprayed out through the high-pressure nozzle to extinguish the fire. When the temporary high-pressure fire water supply system is not in use, there is water inside the water pipe. If this water is not used frequently, it may contain impurities for various reasons, such as sediment, suspended matter, rust, microorganisms, etc. The accumulation of these impurities may cause damage to the internal components of the water supply device, such as clogging the water pump, control valve, nozzle, etc. At this time, if Figure 3As shown, the first flow control valve is opened, the second flow control valve, the third flow control valve and the fourth flow control valve are closed, and the impurity remover is moved up to the inside of the water pipe by rotating the assembly to make the water pump work. The water inside the water tank pushes the impurity remover to flow inside the water pipe by water pressure, thereby removing impurities on the inner wall of the water pipe, and then enters the first conduit again, thereby crossing the pressure regulating valve, and then removes impurities from a part of the pressure regulating valve close to the water spray pipe, and then the water pressure causes the impurity remover to enter the second conduit, and enter the connection shell again through the backflow of the second conduit, and the subsequent staff opens the connection shell to discharge the impurities. The device can clean the impurities inside the water pipe, thereby preventing the water pipe and the nozzle from being blocked, thereby stabilizing the water spray and indirectly improving safety.

[0025] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0026] like Figure 1-4 As shown, the technical solution adopted by the present invention is as follows: an adjustable temporary high-pressure fire water supply device, comprising a water tank 1, a water pipe 2 is installed on one side of the water tank 1, and a high-pressure nozzle 3 is arranged at one end of the water pipe 2 away from the water tank 1;

[0027] The water conduit 2 is provided with a water pump 4, a first flow control valve 5, a debris removal component, a second flow control valve 6, a pressure stabilizing valve 7, a third flow control valve 8, a fourth flow control valve 9, a first conduit 10 and a second conduit 11 in sequence from left to right. One end of the first conduit 10 is located between the first flow control valve 5 and the second flow control valve 6, and the other end of the first conduit 10 is arranged between the third flow control valve 8 and the fourth flow control valve 9. One end of the second conduit 11 is located between the third flow control valve 8 and the fourth flow control valve 9, and the other end of the second conduit 11 is connected to the debris removal component.

[0028] The impurity removal component includes a connecting shell 12 connected to the second conduit 11 and the water conduit 2. A moving component is arranged inside the connecting shell 12. The moving component is provided with an impurity remover 13, which is composed of a sphere and a circular scraper.

[0029] Its working principle is: first open the first flow control valve 5, the second flow control valve 6, the third flow control valve 8 and the fourth flow control valve 9, start the water pump 4, so that the water inside the water tank 1 enters the water pipe 2, and the water inside the water pipe 2 is regulated by the pressure regulating valve 7, so that it is sprayed out through the high-pressure nozzle 3 to extinguish the fire. When the temporary high-pressure fire water supply system is not in use, there is water inside the water pipe 2. If this water is not used frequently, it may contain impurities for various reasons, such as sediment, suspended matter, rust, microorganisms, etc. The accumulation of these impurities may cause damage to the internal components of the water supply device, such as clogging the water pump 4, control valve, nozzle, etc. At this time, if Figure 3 As shown, the first flow control valve 5 is opened, the second flow control valve 6, the third flow control valve 8 and the fourth flow control valve 9 are closed, and the impurity remover 13 is moved up to the inside of the water pipe 2 by rotating the assembly, so that the water pump 4 works, and the water inside the water storage tank 1 pushes the impurity remover 13 to flow inside the water pipe 2 by water pressure, thereby removing impurities on the inner wall of the water pipe 2, and then enters the first conduit 10 again, thereby crossing the pressure regulating valve 7, and then removes impurities from a part of the pressure regulating valve 7 close to the water spray pipe, and then the water pressure causes the impurity remover 13 to enter the second conduit 11, and enter the connection shell 12 again through the backflow of the second conduit 11, and the subsequent staff opens the connection shell 12 to discharge impurities. The device can clean the impurities inside the water pipe 2, thereby preventing the water pipe 2 and the nozzle from being blocked, thereby stabilizing the water spray and indirectly improving safety.

[0030] Among them, a filter housing 14 located inside the water storage tank 1 is provided at one end of the water pipe 2, and the filter housing 14 is provided with filter holes. The property of the filter housing 14 can filter impurities in the impure water.

[0031] Meanwhile, the water pump 4 is a flow water pump 4 in the prior art, an IS100-65-250 centrifugal pump, and the structure of the centrifugal pump mainly includes an impeller, a pump casing, a shaft, a sealing device, etc. Its working principle is to use the rotation of the impeller to generate centrifugal force to suck in and push out the liquid.

[0032] When the centrifugal pump is started, the motor drives the impeller to rotate at high speed. The blades in the impeller generate centrifugal force on the liquid, causing the liquid to flow outward and enter the channel of the pump casing. In the pump casing, due to the effects of inertia and pressure, the liquid flows along the channel to the outlet and is discharged.

[0033] During the flow of liquid, the pump housing forms a gradually expanding cavity, which helps to reduce the flow resistance of the liquid and increase the flow rate. At the same time, centrifugal pumps usually use sealing devices to prevent liquid leakage.

[0034] The working principle of a centrifugal pump is based on the action of centrifugal force. It can effectively transport various liquids, including clean water, sewage, corrosive liquids, etc. The advantages of a centrifugal pump are large flow, high head, simple structure, easy maintenance, etc., so it is widely used in industry, agriculture, municipal administration and other fields.

[0035] The models of the first flow control valve 5, the second flow control valve 6, the third flow control valve 8, the fourth flow control valve 9 and the fifth flow control valve 20 are all LC-10 flow control valves. The flow control valve is a device used to adjust and control the flow of fluid, and its structure and working principle may vary depending on the different types of control valves.

[0036] structure:

[0037] 1. Valve body: The main part of the control valve, usually with inlet and outlet, used to connect the pipeline.

[0038] 2. Valve core: A movable part located inside the valve body that adjusts the flow rate by changing its position.

[0039] 3. Valve seat: A sealing component that matches the valve core and is used to control the flow of fluid.

[0040] 4. Drive device: used to control the movement of the valve core. Common drive methods include manual, electric, pneumatic, etc.

[0041] 5. Sensor or measuring device: used to detect parameters such as flow or pressure and provide feedback signals for the control valve.

[0042] Working principle:

[0043] The flow control valve changes the cross-sectional area of ​​the fluid channel by changing the position of the valve core, thereby adjusting the flow rate. When the drive receives a control signal, it controls the movement of the valve core to change the size of the opening between it and the valve seat. In this way, the flow rate of the fluid through the control valve will change accordingly. For example, in a throttling flow control valve, the valve core is usually conical or plunger-shaped. By rotating or moving the valve core, the cross-sectional area of ​​the fluid channel can be reduced or increased, thereby limiting or increasing the flow rate. In a control valve, the position of the valve core can be continuously adjusted to achieve more precise flow control.

[0044] The model of the pressure regulating valve 7 is RV-10 pressure regulating valve 7. The pressure regulating valve 7 is a device used to stabilize the system pressure. Its structure and working principle are as follows:

[0045] structure:

[0046] 1. Bonnet: The bonnet is located above the valve body and is sealed to the valve body. It usually contains an adjustment device or pressure indicator.

[0047] 2. Valve body: The valve body is the main part of the pressure regulating valve 7, with a valve seat and a valve core inside.

[0048] 3. Valve core: The valve core is a movable component that cooperates with the valve seat inside the valve body to regulate the passage of fluid.

[0049] 4. Spring: The spring is used to apply pressure to the valve core to keep it in a certain position.

[0050] 5. Valve seat: The valve seat contacts the valve core to form a sealing surface to control the flow of fluid.

[0051] Working principle:

[0052] The working principle of the pressure regulating valve 7 is based on the force of the spring and the regulating effect of the valve core. When the system pressure increases, the force of the fluid on the valve core also increases. When the pressure exceeds the set force of the spring, the valve core will move upward, reducing the opening of the valve seat, thereby reducing the amount of fluid passing through and causing the system pressure to drop. When the system pressure drops, the force of the spring moves the valve core downward, increasing the opening of the valve seat, increasing the amount of fluid passing through and causing the system pressure to rise.

[0053] Through this automatic adjustment process, the pressure-stabilizing valve 7 can keep the system pressure stable near the set value. The pressure-stabilizing valve 7 can adjust the range and accuracy of the pressure stabilization by adjusting the preload of the spring or changing the shape and size of the valve core.

[0054] It should be noted that the working principles and structures of the water pump 4, the control valve and the pressure-stabilizing valve 7 all belong to the prior art and will not be described in detail here.

[0055] In order to enable the impurity remover 13 to move inside the first conduit 10, the second conduit 11 and the water pipe 2, the diameters of the first conduit 10, the second conduit 11 and the water pipe 2 are the same as the diameter of the impurity remover 13. This arrangement enables the impurity remover 13 to move inside the first conduit 10, the second conduit 11 and the water pipe 2 under the action of water pressure.

[0056] The material of the impurity remover 13 is plastic, and such arrangement enables it to be light in weight and easily pushed by water pressure.

[0057] The moving component includes a sealing cover 15 arranged on the connecting shell 12, and a threaded hole is opened on the sealing cover 15. A threaded rod 16 is arranged inside the threaded hole. A bearing plate 17 is arranged on the top of the threaded rod 16, and a rotating disk 18 is arranged on the bottom of the threaded rod 16. The rotating disk 18 drives the threaded rod 16 to rotate inside the threaded hole, thereby driving the bearing disk to move the impurity remover 13 to the inside of the water pipe 2 to work.

[0058] The sealing cover 15 is detachably connected to the connecting housing 12, and such an arrangement enables the removal of impurities and sealing.

[0059] It should be noted that when the dust collector 13 is moved by water pressure, the rotating disk 18 is required to drive the threaded rod 16 to rotate inside the threaded hole, thereby driving the carrier disk to return to its original position, so that the dust collector 13 can enter when it returns.

[0060] The water conduit 2 is also provided with a pressure gauge 19 , through which the pressure inside the water conduit 2 can be viewed.

[0061] A fifth flow control valve 20 is provided on the first conduit 10 and the second conduit 11, and the opening and closing of the first conduit 10 and the second conduit 11 are controlled by the fifth flow control valve 20. When impurities removal is required, the first flow control valve 5 and the fifth flow control valve 20 are opened, and the second flow control valve 6, the third flow control valve 8 and the fourth flow control valve 9 are closed. When impurities removal is not required, the fifth flow control valve 20 is closed, and the first flow control valve 5, the second flow control valve 6, the third flow control valve 8 and the fourth flow control valve 9 are opened for operation.

[0062] It should be noted that the drawings of the present invention are only to help people understand, and the sizes, specifications and shapes therein can be designed by professionals, so they will not be explained here.

[0063] The working principle of the utility model is as follows: firstly, the first flow control valve 5, the second flow control valve 6, the third flow control valve 8 and the fourth flow control valve 9 are opened, and the water pump 4 is started, so that the water inside the water tank 1 enters the water pipe 2, and the water inside the water pipe 2 is regulated by the pressure regulating valve 7, so that it is sprayed out through the high-pressure nozzle 3 to extinguish the fire. When the temporary high-pressure fire water supply system is not in use, there is water inside the water pipe 2. If the water is not used frequently, it may contain impurities for various reasons, such as sediment, suspended matter, rust, microorganisms, etc. The accumulation of these impurities may cause damage to the internal components of the water supply device, such as clogging the water pump 4, control valve, nozzle, etc. At this time, if Figure 3 As shown, the first flow control valve 5 is opened, the second flow control valve 6, the third flow control valve 8 and the fourth flow control valve 9 are closed, and the impurity remover 13 is moved up to the inside of the water pipe 2 by rotating the assembly, so that the water pump 4 works, and the water inside the water storage tank 1 pushes the impurity remover 13 to flow inside the water pipe 2 by water pressure, thereby removing impurities on the inner wall of the water pipe 2, and then enters the first conduit 10 again, thereby crossing the pressure regulating valve 7, and then removes impurities from a part of the pressure regulating valve 7 close to the water spray pipe, and then the water pressure causes the impurity remover 13 to enter the second conduit 11, and enter the connection shell 12 again through the backflow of the second conduit 11, and the subsequent staff opens the connection shell 12 to discharge impurities. The device can clean the impurities inside the water pipe 2, thereby preventing the water pipe 2 and the nozzle from being blocked, thereby stabilizing the water spray and indirectly improving safety.

[0064] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
