How to pay attention to the internal structure of stainless steel water tank

Release date: April 24, 2020 Number of visits: four hundred and forty-eight

Water inlet pipe: the water inlet pipe of the water tank is generally connected from the outer wall, or from the bottom or top. When Stainless steel water tank When water pressure is used to feed water through pipeline network, hydraulic level control valve or floating ball valve shall be installed at the water outlet of inlet pipe as much as possible, and the top of control valve shall be connected with water tank. When the pipe diameter is greater than or equal to 50 mm, the number of such valves shall not be less than 2. Each control valve should be equipped with maintenance valve. When the water tank uses the water pressure of the booster pump to leak water and uses the water level elevator to automatically control the operation of the pressure pump, the water level line pressure regulating valve cannot be installed.


2. Outlet pipe: the water outlet pipe of the water tank can be connected from the outer wall or the bottom end. The inner bottom of outlet pipe (external wall connected) or branch pipe wall top (bottom end connected) shall be higher than the inner bottom of water tank by more than 50mm. The outlet pipe should be set with thread (diameter) or flange (large size) stop valve, and it is not allowed to install the stop valve with great force. When it is necessary to refit the product, the swing type with low friction resistance should be selected instead of the lifting mechanism. The minimum water level of the water tank at the elevation of check valve is more than 1m. When a stainless steel water tank is used for domestic and fire protection, the product on the fire safety outlet pipe should be less than the top of the domestic water siphon (when the water level is less than the top of the pipe, the vacuum pump of the life siphon will be destroyed, only the water will flow out of the fire water outlet pipe) Many of them are more than 2m, so that they have certain water pressure promotion products. In case of fire accidents, the fire safety reserve water flow can be truly brought into full play.


The stainless steel water tank shared by fire safety and life should not only ensure the flow of fire safety reserve water but also reduce the area of turbid water as far as possible. For example, the domestic outlet pipe should use siphon pipe top drilling (diameter is 0.1 times of the pipe diameter) and other countermeasures, such as stainless steel water tank.

3. Drain pipe: the drain pipe of water tank shall be connected from the bottom at least. The drain pipe is equipped with thread or flange gate valve (stop valve is not allowed). The drain pipe can be connected to the overflow water pipe, but not to the drainage equipment immediately. When there is no requirement, the diameter of drainage pipe shall not be less than 50mm.


4. Vent pipe: the water tank for domestic water shall be provided with a sealed box cover under it, and the maintenance hand hole and vent pipe shall be set on the machine cover. The ventilation pipe can be extended to the room or outdoor, only the area with harmful substances can not be extended. The branch pipe should be equipped with a filter screen to avoid dust, insects and mosquitoes. Generally, the branch pipe should be set downward. Do not place gate valve, exhaust valve and other equipment on the vent pipe to prevent ventilation. The vent pipe shall not be connected to the drainage equipment and ventilation duct. The diameter of ventilation pipe shall not be less than 50mm.


5. Liquid level gauge: generally, glass level gauge shall be installed on the outer wall of stainless steel water tank to mark water level line locally. When the length of a liquid level transmitter is not enough, two or more can be installed on the left and right. Adjacent to the overlapping part of two liquid level transmitters, it is not suitable to be lower than 70mm, as shown in figure 1.8-3. If the data signal countdown of liquid level meter is installed at the end of water tank, data signal tube shall be set to obtain the data signal of water gushing. The data signal pipe is generally connected from the outer wall of the water tank, and its height width ratio should be set to make the middle bottom of the pipe flush with the inner bottom of the overflow water pipe or the overflow river surface at the top of the wall at the bell mouth stage.




6. Overflow pipe: the overflow water pipe of stainless steel water tank can be connected from the outer wall or bottom end. The diameter of the pipe should be 1-2 larger than that of the water inlet pipe, but the pipe below LM at the bottom of the water tank can be reduced to the diameter of the water inlet pipe with a reducing three-way. Do not install gate valve on warm water pipe. The overflow water pipe can not be connected with the drainage equipment immediately, so the simple connection drainage pipe must be selected. Measures should be taken to prevent dust, insects and mosquitoes from entering the overflow water pipe, such as setting exhaust valve and filter screen.
