Description

Flexible living and fire water tank

technical field

The utility model "flexible living and fire-fighting water tank" is a device for water supply for living and fire-fighting in high-rise buildings. It is a water tank device that can isolate water pollution from the outside world and increase the water pressure of fire-fighting water supply for high-rise buildings.

Background technique

Existing high-rise building domestic water and fire-fighting water supply water tank structures are all made of hard materials such as metal, glass fiber reinforced plastics, cement, and its structure is generally divided into two classes, namely open water tank and frequency conversion type water supply tank. The open water tank is easy to pollute the water during use, the disinfectant added by the water plant is easy to escape, and the low pressure of the water outlet is very unfavorable to the fire water, and it needs to be cleaned frequently. The frequency conversion water supply tank consumes a lot of power, and the water will be cut off when the power is off, requiring frequent maintenance, especially not suitable for fire protection.

Contents of the invention

In view of the fact that the existing high-rise building domestic water and fire-fighting water supply tanks are easy to pollute the water during use, and the low outlet pressure is very unfavorable to the fire-fighting water, the utility model uses flexible materials to make a flexible closed water tank body, which can effectively Isolate external pollution and increase water pressure.

The technical scheme adopted by the utility model is: the water tank box body is made of flexible materials, and a counterweight is arranged on the box body. Its overall system structure is: a closed water tank made of flexible materials, the box can withstand a certain pressure, there are positioning columns around it, a balance limit spring is hung on the column, and a counterweight is hung on the balance limit spring. The weight is placed above the flexible water tank, and the counterweight applies preload to the water tank. When the water tank is filled with water, the water tank bulges, and when the water is released, the water body in the tank gets a larger pre-compression under the action of the counterweight, so that the water supply outlet of the water tank has a larger water outlet pressure.

The beneficial effect of the utility model is that its good sealing ensures clean domestic water, and the pre-pressure generated by the counterweight can make the water supply outlet of the water tank have a larger water outlet pressure, which ensures the water pressure of fire-fighting water during power failure.

Detailed ways

Show the principle diagram of the utility model in Fig. 1, municipal tap water enters flexible living and fire-fighting water tank casing (1) through tap water inlet (12), water pump (8), water inlet pipe (9). The counterweight body (2) is placed on the casing (1) of the flexible domestic and fire-fighting water tank, and preload is applied thereto. The domestic water is output by the domestic water outlet (10), and the fire-fighting water is output by the fire-fighting water outlet (11).

In Fig. 2, the structure diagram of the embodiment of the utility model is shown, the municipal tap water enters the flexible living and fire fighting water tank through the tap water inlet (12), the water pump (8), the water inlet pipe (9) through the water inlet check valve (13) Casing (1), the effect of water inlet non-return valve (13) is to prevent the backflow of the water that enters flexible living and fire-fighting water tank casing (1) when water pump (8) stops running; Flexible living and fire-fighting water tank casing ( 1) A positioning column (4) is fixed around it, and a balance limit spring (3) is hung on its upper end. The counterweight body (2) is in the correct position on the flexible domestic and fire-fighting water tank body (1), and the counterweight body (2) is just connected to the other end of the balance limit spring (3); there is a water level sensor on the counterweight body (2). 6), used to sense the change in the up and down position of the counterweight body (2) caused by the change in the water level in the flexible domestic and fire water tank (1), and convert this position change into an electrical signal, which is passed through the sensor cable (14 ) to the water inlet controller (7); the water inlet controller (7) controls the water pump (8) to rotate or stop after receiving the signal from the water level sensor (6); the domestic water is supplied by the flexible living and fire water tank ( 1) The domestic water outlet (10) in the middle is output to ensure water quality, and the fire-fighting water is output from the fire-fighting water outlet (11) at the bottom of the flexible domestic and fire-fighting water tank (1) to ensure the maximum water consumption for fire-fighting. The safety valve (5) is a device used to prevent overpressure damage to the flexible living and fire water tank body (1).

Its working process is as follows: when water is supplied, the water pump (8) sends water into the flexible domestic and fire-fighting water tank (1), the flexible domestic and fire-fighting water tank (1) expands accordingly, and the water level sensor (6) indicates the storage capacity of the water tank. When the water storage reaches the expected volume, the water inlet controller (7) sends a control command, and the water pump (8) stops running. After the water pump (8) stops running, the water inlet check valve (13) on the water inlet pipe (9) closes the water inlet. The water in the flexible domestic and fire-fighting water tank body (1) is supplied to users from the domestic water outlet (10), and a water source is provided for fire-fighting from the fire-fighting water outlet (11). When the water in the flexible domestic and fire-fighting water tank (1) is consumed to a certain extent, the water level sensor (6) sends a message, the water inlet controller (7) sends a control command, starts the water pump (8) and repeats the water filling process.
