2022 First-level registered fire engineer technical practice test point high-level fire water tank should comply with the provisions of
1 The effective volume, water outlet, drainage and water level of high-level fire water tank should comply with the provisions of Article 4.3.8 and Article 4.3.9 of this specification;
2 The minimum effective water level of a high-level fire water tank should be determined based on the flooding depth of the outlet pipe flare and the prevention cyclone flare . When the outlet pipe flare flare, it should comply with the provisions of Article 5.1.13, paragraph 4 of this specification; when a preventing cyclone is used, it should be determined based on the product, and the protection height should not be less than 150mm;
3 The ventilation pipes, breathing pipes, etc. of high-level fire water tanks should comply with the provisions of Article 4.3.10 of this Code;
4 The clear distance between the outer wall of the high-level fire water tank and the wall of the building body structure or other pool walls should meet the needs of construction or assembly. The clear distance between the sides without pipes should not be less than 0.7m; the clear distance between the sides of the pipes installed should not be less than 1.0m, and the width of the passage between the outer wall of the pipe and the wall of the building body should not be less than 0.6m. The top of the water tank with a manhole should not be less than 0.8m. The clearance between the top of the top surface and the bottom of the building body plate above it should not be less than 0.8m;
5 The diameter of the water inlet pipe should meet the fire water tank 8h The requirement is to be filled with water, but the pipe diameter should not be less than DN32. The water inlet pipe should be equipped with a liquid level valve or float valve ;
6 The water inlet pipe should be connected above the overflow water level. The height of the lowest point of the water inlet pipe mouth above the overflow edge should be equal to the pipe diameter of the water inlet pipe, but the minimum should not be less than 100mm and the maximum should not be greater than 150mm;
7 When the water inlet pipe is flooded out of the flow, measures should be set on the water inlet pipe to prevent backflow or siphon damage holes and vacuum destroyers should be set on the pipe. The hole diameter of the siphon damage hole should not be less than 1/5 of the diameter of the pipe, and should not be less than 25mm. However, when using domestic water supply system to replenish water, the water inlet pipe should not flood the outflow; 1 The effective volume, water outlet, drainage and water level of the high-level fire water tank should comply with Article 4.3.8 and Article 4.3.9 of this Code;
2 The minimum effective water level of the high-level fire water tank should be determined based on the flooding depth of the outlet pipe flare and the preventing cyclone. When using the outlet pipe flare, it should comply with the provisions of Article 5.1.13, paragraph 4 of this Code; when using the anti-cyclone, it should be determined based on the product, and the protection height should not be less than 150mm;
3 The ventilation pipes, breathing pipes, etc. of the high-level fire water tank should comply with the provisions of Article 4.3.10 of this Code;
4 The clear distance between the outer wall of the high-level fire water tank and the wall of the building body structure or other pool walls should meet the needs of construction or assembly. The clear distance between the sides without pipes should not be less than 0.7m; the clear distance between the sides of the pipes installed should not be less than 1.0m, and the width of the passage between the outer wall of the pipe and the wall of the building body should not be less than 0.6m. The top of the water tank with manholes should be, and the clearance between the top surface and the bottom of the building body panel above it should not be less than 0.8m;
5 The pipe diameter of the water inlet pipe should meet the requirements of the fire water tank being filled with water for 8 hours, but the pipe diameter should not be less than DN32. The water inlet pipe should be equipped with a liquid level valve or float valve;
6 The water inlet pipe should be connected above the overflow water level. The height of the lowest point of the water inlet pipe mouth above the overflow edge should be equal to the diameter of the water inlet pipe, but the minimum should not be less than 100mm and the maximum should not be greater than 150mm;
7 When the water inlet pipe is flooded out of the flow, measures should be set on the water inlet pipe to prevent backflow or siphon damage holes and vacuum destroyers should be set on the pipe. The aperture of the siphon damage hole should not be less than 1/5 of the diameter of the pipe, and should not be less than 25mm. However, when using the domestic water supply system to replenish water, the water inlet pipe should not be submerged and outflowed;
