Gannan effective volume 11 cubic stainless steel fire water tank

Description :

　　Internal structure of stainless steel water tank

　　1. Inlet pipe: The inlet pipe of the water tank is generally connected from the outer wall, but can also be connected from the bottom or top. When the water tank is filled with water pressure from the pipeline network, hydraulic water level control valves or floating balls should be installed as much as possible at the water outlet of the inlet pipe

　　The valve is connected to the water tank at the top of the control valve. When the pipe diameter is ≥ 50MM, the number of valves is generally not less than 2. Each control valve should be equipped with a maintenance valve in front of it. When the water tank leaks water due to the pressure of the booster pump and the water level line elevator is used to lift it

　　When the dynamic control pressure pump is operating, it is not allowed to install a water level pressure regulating valve.

　　2. Outlet pipe: The outlet pipe of the water tank can be connected from the outer wall or bottom end. The inner bottom of the water outlet pipe (connected to the outer wall) or the top of the branch pipe wall (connected to the bottom end) should be more than 50MM higher than the inner bottom of the water tank. The water outlet pipe should be set with threads (diameter) or flanges

　　(Large size) globe valves are not allowed to be installed with high installation force. When it is necessary to modify the product, a rotary type with lower friction resistance should be used instead of a lifting mechanism. The check valve elevation of the water tank is less than 1M, and the water level line is much higher than 1M,

　　When living and firefighting are combined into one water tank, the product on the fire safety outlet pipe should be smaller than the top of the domestic siphon pipe (when it is smaller than this pipe top, the vacuum pump of the domestic siphon pipe is damaged, only ensuring that there is water flowing out of the fire outlet pipe)

　　Many of them are larger than 2M, which enables them to have a certain water pressure to promote the product. In the event of a fire accident, the fire safety reserve water flow can truly be fully utilized.

　　In addition to technical measures to ensure that the water storage flow for fire safety and daily life is not used for other purposes, water tanks shared by fire safety and daily life should also minimize the occurrence of turbid water areas. For example, siphon pipes with top drilled holes (diameter of pipe diameter) should be used for domestic water outlet pipes

　　Countermeasures such as 0.1 times the stainless steel water tank

　　3. Drainage pipe: The water tank drainage pipe should be connected from the bottom at a few places. The drainage pipe is equipped with threaded or flanged gate valves (globe valves cannot be installed). The drainage pipe can be connected to the overflow water pipe, but cannot be immediately connected to the drainage equipment.

　　When there is no requirement for the diameter of the drainage pipe, it is generally not less than 50MM.

　　4. Ventilation pipe: A sealed box cover should be placed under the water tank for domestic water supply, and a maintenance hand hole and ventilation pipe should be placed under the machine cover. The ventilation pipe can be extended into the room or outdoors, and should not be extended into areas with harmful substances. Branch pipes

　　There should be a filter screen to prevent dust, insects, and mosquitoes from entering, and the branch pipe should generally be set facing downwards. Gate valves, exhaust valves, and other devices that obstruct ventilation should not be installed on the ventilation pipe. Ventilation pipes should not be connected to drainage equipment and ventilation ducts

　　connect. The diameter of the ventilation pipe is generally not less than 50MM. Stainless steel water tank

　　5. Liquid level gauge: Generally, a glass liquid level gauge should be installed on the outer wall of the water tank to indicate the water level line on site. When the length of a liquid level transmitter is insufficient, two or more can be installed on both sides. Adjacent to 2 liquid level transmitters

　　The overlapping part should not be lower than 70mm, as shown in Figure 1.8-3. If a liquid level meter data signal countdown is installed at the end of the water tank, a data signal tube should be installed to obtain the water leakage data signal. The data signal tube is generally from the water tank

　　The outer wall is connected, and its height to width ratio should be set so that the bottom of the pipe is flush with the bottom of the overflow water pipe or the top of the wall during the bell mouth period.

　　6. Overflow pipe: The overflow water pipe of the water tank can be connected from the outer wall or bottom end. Its diameter should be 1-2 sizes larger than the inlet pipe, but the pipes below LM at the bottom of the water tank can be reduced to a diameter equivalent to that of the inlet pipe using three reducers. Warm open water pipe

　　Gate valves cannot be installed on top. Overflow water pipes should not be immediately connected to drainage equipment, and simple drainage pipes must be selected. Measures should be taken on the overflow water pipe to prevent dust, insects, mosquitoes, etc. from entering, such as setting up exhaust

　　Valves, filters, etc.
