Description

Technical Field

[0001] This utility model relates to the field of fire pump pressure stabilization technology, and in particular to a fire pump pressure stabilization device. Background Technology

[0002] Fire pump pressure stabilizing devices have multiple important applications. They continuously monitor and automatically adjust the pressure of the fire pipeline network, maintaining its stability under normal fire conditions and preventing pressure fluctuations caused by environmental factors. In the event of a fire, they ensure the rapid response capability of the fire protection system, allowing sprinklers or fire hydrants to quickly deliver water under pressure, effectively controlling the spread of fire. Furthermore, they reduce the frequent starting of the main fire pump, preventing the high-power pump from repeatedly starting due to minor pressure fluctuations in the pipeline network, saving energy, extending the service life of the main pump, and reducing the operating costs of the fire protection system. They are one of the key components for the stable and reliable operation of the fire protection system.

[0003] The fire pump pressure stabilizing device currently in use mainly consists of a pressure stabilizing pump, a pressure tank, a pressure sensor, and a controller. During operation, the pressure sensor is installed at a critical location in the fire pipeline network to monitor water pressure in real time and transmit the signal to the controller. The controller compares the preset upper and lower pressure limits. When the pipeline pressure is below the lower limit, the pressure stabilizing pump is started to draw water from the water source and inject it into the pipeline network. When the pressure rises to the upper limit, the pump stops. The pressure tank is pre-filled with gas, storing some water when the pressure stabilizing pump injects water. After the pump stops, the gas expands and displaces the water to assist in pressure stabilization, reducing the frequency of pump starts. If a fire or other event causes a sharp drop in pipeline pressure that the pressure stabilizing pump cannot recover, the controller will start the main fire pump. The pressure stabilizing device continues to monitor the pressure, working in conjunction with the main pump to ensure the stable operation of the fire protection system.

[0004] While the aforementioned devices ensure the stable operation of the fire protection system, they are currently connected to the water inlet using bolts, which is cumbersome and prone to corrosion and rust over time, affecting the stability of the interface. Therefore, a fire pump pressure stabilizing device is proposed to solve these problems. Utility Model Content

Detailed Implementation

[0031] 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.

[0032] Reference Figure 1 and Figure 2This utility model provides an embodiment of a fire pump pressure stabilizing device, comprising a base 1, a connecting block 17 slidably connected to the side of the base 1, a disassembly assembly installed on the side of the connecting block 17, a fixing rod 4 fixedly connected to the top of the base 1, a flow pipe 8 fixedly connected to the top of the fixing rod 4, a connecting assembly provided on the outer periphery of the flow pipe 8, a pressure stabilizing tank 9 fixedly connected to the top of the base 1, and a centrifugal pump 7 fixedly connected to the top of the connecting block 17; the connecting assembly includes a connecting ring 16, the inner side of the connecting ring 16 fixedly connected to the outer periphery of the flow pipe 8, and a fixing device snapped onto the outer periphery of the connecting ring 16. Block 14, a movable ring 13 is slidably connected to the outer periphery of the fixed block 14. The movement of the movable ring 13 will cause the fixed block 14 to be locked and fixed with the connecting ring 16. An electric push rod 12 is fixedly connected to the side of the movable ring 13. The operation of the electric push rod 12 will drive the movable ring 13 to move. A fixed ring 11 is fixedly connected to the bottom of the electric push rod 12. The fixed ring 11 is used to support and fix the electric push rod 12, thereby facilitating the operation of the electric push rod 12. A water inlet pipe 10 is fixedly connected inside the fixed ring 11, thereby connecting the water inlet pipe 10 and the flow pipe 8.

[0033] Reference Figure 1 , Figure 3 and Figure 4 The disassembly assembly includes a mounting bracket 20, the side of which is fixedly connected to the side of a connecting block 17. A connecting rod 18 is slidably connected inside the mounting bracket 20. The connecting rod 18 is interlocked with the connecting block 17 and the base 1. By pulling the connecting rod 18 outward, the connecting rod 18 is disengaged from the connecting block 17, allowing the connecting block 17 and the centrifugal pump 7 to be removed directly, facilitating maintenance and replacement of the centrifugal pump 7. A crossbar 21 is fixedly connected to the side of the connecting rod 18, and a spring 19 is fixedly connected to the inside of the mounting bracket 20. When installing the centrifugal pump 7, the connecting rod 18 is fixedly interlocked with the inside of the connecting block 17. At the same time, under the tension of the spring 19 returning to its original position, the crossbar 21 makes the connecting rod 18 more securely interlocked inside the connecting block 17. A support block 22 is fixedly connected inside the mounting bracket 20. When the connecting rod 18 is pulled outward, the support block 22 can support the crossbar 21, facilitating subsequent operations by the staff.

[0034] Reference Figure 1 and Figure 2A washer 15 is fixedly connected to the side of the connecting ring 16. The washer 15 is not limited to rubber material. The washer 15 improves the sealing performance at the interface between the flow pipe 2 8 and the water inlet pipe 10. A flow pipe 1 5 is fixedly connected inside the centrifugal pump 7 and the pressure stabilizing tank 9. One end of the flow pipe 1 5 is fixedly connected to the inside of the flow pipe 2 8. This allows the centrifugal pump 7 to increase the water pressure to meet the fire water demand. The pressure stabilizing tank 9 can reduce the pump's starting frequency and increase its service life. A valve 6 is installed on the outer periphery of the flow pipe 1 5. Multiple valves 6 are provided to control the flow of the flow pipe 1 5. A bolt 2 is slidably connected inside the base 1. A nut 3 is threadedly connected to the outer periphery of the bolt 2, which facilitates the overall installation of the device. Multiple fixing blocks 14 are provided. All fixing blocks 14 are engaged with the connecting ring 16. The engagement effect of the multiple fixing blocks 14 is improved.

[0035] Working principle: First, when connecting the flow pipe 2 8 to the inlet pipe 10, the electric push rod 12 drives the moving ring 13 to move. Under the action of the moving ring 13, the fixing block 14 deforms and is fixed on the outer periphery of the connecting ring 16. This allows for quick connection between the inlet pipe 10 and the flow pipe 2 8, making operation convenient and improving work efficiency. Second, when maintenance or replacement of the centrifugal pump 7 is required, pulling the connecting rod 18 causes the spring 19 to contract under the action of the crossbar 21. At the same time, the connecting rod 18 disengages from the interior of the base 1, allowing the centrifugal pump 7 to be directly removed for maintenance and replacement via the connecting block 17. During installation, releasing the connecting rod 18 causes the connecting rod 18 to engage with the connecting block 17 and the interior of the base 1 under the tension of the spring 19 returning to its original position. This enables the installation of the centrifugal pump 7, making operation convenient, facilitating maintenance and replacement of the centrifugal pump 7, and ensuring working effect.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
