Description

Technical Field

[0001] This utility model relates to the field of fire water pipes, and more particularly to fire water pipes that can be pressure-adjusted. Background Technology

[0002] Automatic sprinkler systems are recognized worldwide as one of the most effective fire extinguishing facilities. They are characterized by safety, reliability, economy, practicality, and high fire extinguishing success rate. Statistics show that in warehouse fires, the fire extinguishing success rate of automatic sprinkler systems is as high as 89.9%.

[0003] During the use of automatic sprinkler systems, the water supply for these systems is mostly obtained from fire pools. However, the supply from fire pools is limited and cannot support large-scale fires. Furthermore, when an automatic sprinkler system is connected to an external water source, the excessive pressure of the external water source can easily damage the internal components and connections of the automatic sprinkler system, affecting its applicability.

[0004] Therefore, given that the existing automatic sprinkler systems mostly rely on fire pools for water supply, which have limited capacity and cannot support large-scale fires, and that excessive external water pressure can damage internal components and connections, affecting the system's applicability, a pressure-regulating fire hose can be designed. This hose provides dual water supply via both a fire pool and a municipal water supply pipe, ensuring a continuous and stable water supply to the sprinkler system and mitigating the significant safety risks associated with water shortages. A gate valve at the top of the municipal water supply pipe controls the flow of municipal water, a check valve prevents backflow of sprinkler system water into the municipal network, and a pilot-operated pressure reducing valve lowers the pressure. Furthermore, when the municipal water supply pipe is connected to other equipment, clamping blocks secure the connection to prevent excessive water pressure from causing the pipe to detach. Utility Model Content

Furthermore, when the municipal water supply pipe is connected to other equipment, clamping blocks are used to hold the pipe connections in place to prevent excessive water pressure from causing the pipe to detach.

[0008] As a preferred option, the municipal water supply pipe and the connector are integrated into one structure, and the municipal water supply pipe and the connector are connected by welding.

[0009] Preferably, there are three guide seats, and a guide groove is provided on the inner side of the guide seat above the clamping block. The clamping block is movably connected to the guide seat through the guide groove.

[0010] Preferably, the transmission gear has gears at both the upper and lower ends, and the rear end of the transmission gear extends to the outer side of the transmission ring, with the transmission gear meshing with the transmission ring.

[0012] Preferably, the bottom of the clamping block is arc-shaped, and the clamping block is an arc-shaped block.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-4 This utility model provides an embodiment of a fire water pipe capable of pressure regulation, comprising a fire water tank 1, a fire connection pipe 2 at the top of the fire water tank 1, a municipal water supply pipe 3 on one side of the fire connection pipe 2, a check valve 5, a pilot-operated pressure reducing valve 4, and a rising stem gate valve 6 sequentially arranged at the top of the municipal water supply pipe 3, a connecting seat 7 at the front end of the municipal water supply pipe 3, the municipal water supply pipe 3 and the connecting seat 7 being an integral structure, connected by welding, a guide seat 8 at the front end of the connecting seat 7, and a clamping block 10 on the inner side of the guide seat 8. A transmission gear 9 is provided on one side of the 10. The rear end of the transmission gear 9 is located inside the connecting seat 7 and is provided with a transmission ring 11. It is then connected to the municipal water supply connection mechanism through the fire water tank 1 and the municipal water supply pipe 3, thereby realizing dual water supply. The fire sprinkler system has a continuous and stable water supply, avoiding the major safety hazard of no water. A check valve 5, a pilot-operated pressure reducing valve 4 and a rising stem gate valve 6 are provided in sequence at the top of the municipal water supply pipe 3. The rising stem gate valve 6 is used to switch the municipal water supply on and off, the check valve 5 prevents the water supply of the sprinkler mechanism from flowing back to the municipal pipe network, and the pilot-operated pressure reducing valve 4 reduces the pressure of the municipal water supply.

[0023] Please see Figures 3-4In this embodiment, three guide seats 8 are provided. A guide groove is provided on the inner side of the guide seat 8 above the clamping block 10. The clamping block 10 is movably connected to the guide seat 8 through the guide groove. Gears are provided at both the upper and lower ends of the transmission gear 9. The rear end of the transmission gear 9 extends to the outer side of the transmission ring 11. The transmission gear 9 and the transmission ring 11 mesh with each other. A tooth block 12 is provided on one side of the transmission gear 9 on the outer side of the clamping block 10. The transmission gear 9 and the tooth block 12 mesh with each other. The bottom end of the clamping block 10 is arc-shaped. The clamping block 10 is an arc block. By rotating one of the transmission gears 9, the other transmission gears 9 are driven to rotate through the transmission ring 11. Thus, the clamping block 10 is moved inside the guide seat 8 by the transmission gears 9, so that the clamping block 10 can clamp the water pipe connection and prevent the water pipe from falling off due to excessive water pressure.

[0024] Please see Figures 1-2 The top of the fire connection pipe 2 is equipped with multiple electronic control valves and connecting nozzles, and fire fighting is carried out through the fire connection pipe 2.

[0025] When in operation, the power is turned on and the device is started. Dual water supply is achieved through the fire water tank 1 and the municipal water supply pipe 3, ensuring a continuous and stable water supply to the fire sprinkler system and avoiding the major safety hazards of waterlessness. The top of the municipal water supply pipe 3 is equipped with a check valve 5, a pilot-operated pressure reducing valve 4, and a rising stem gate valve 6. The rising stem gate valve 6 controls the municipal water supply, the check valve 5 prevents the water supply from the sprinkler mechanism from flowing back into the municipal pipe network, and the pilot-operated pressure reducing valve 4 reduces the pressure of the municipal water supply. By rotating one of the transmission gears 9 at the front end of the rotating connecting seat 7, one of the transmission gears 9 drives the other transmission gears 9 to rotate through the transmission ring 11. This causes the clamping block 10 to move inside the guide seat 8, facilitating the clamping block 10 to clamp the water pipe connection and preventing the water pipe from falling off due to excessive water pressure.

[0026] Through the above steps, a dual water supply is achieved through the fire water tank 1 and the municipal water supply pipe 3, ensuring a continuous and stable water supply for the fire sprinkler system and avoiding the significant safety risks associated with water shortages. The municipal water supply is switched on and off by the exposed stem gate valve 6 at the top of the municipal water supply pipe 3, the check valve 5 prevents the water supply from the sprinkler mechanism from flowing back into the municipal pipe network, and the pilot-operated pressure reducing valve 4 reduces the pressure of the municipal water supply. When the municipal water supply pipe 3 is connected to other equipment, the clamping block 10 clamps the pipe connection to prevent the pipe from falling off due to excessive water pressure. This addresses the problem that most existing automatic sprinkler systems rely solely on fire water tanks for water supply, which are limited and do not support large fires. Furthermore, when the automatic sprinkler system is connected to an external water source, excessive external water pressure can easily damage the internal components and connections of the automatic sprinkler system, affecting its applicability.
