Abstract
The utility model relates to a secondary constant pressure water supply device for resident buildings, which is mainly composed of a constant pressure water supply part (5) which is composed of a primary water tank (1), a water pump (3) and a constant pressure controller (4) and a back end water supply pipe (6). the back end water supply pipe (6) directly leads to a water service pipe of each resident, and the upper side of the water service pipe is communicated with a fire-fighting water supply pipe (8). The tail end of the fire-fighting water supply pipe (8) is provided with a secondary water storage tank (9) and fire-fighting water output pipes (10) leading to each fire hydrant. The utility model solves the problems of secondary water pollution, unstable water pressure, no fire-fighting water or insufficient fire-fighting water pressure existing in the water supply device at present, and is used for water supply of the resident buildings.
Description
The utility model relates to a kind of building waterworks, particularly a kind of secondary constant pressure water-supply device that is formed by original high rise building water supply system reform.
At present, the secondary constant pressure water-supply device that highrise building uses, mostly form by water tank, water pump, two sub-reservoirs and a respective line, two sub-reservoirs are arranged on the building eminence, each floor water pipe and each fire plug all are communicated with it by respective line, therefore its shortcoming is, the use of two sub-reservoirs easily causes the drinking water secondary pollution, and pressure of supply water is also unstable.After this people partly directly supply water to each floor resident by feed pipe with a constant pressure water-supply that is made of water pump and constant-voltage controller, because leading to the supply channel of secondary water tank is cut off, cause not having water for fire in the water for fire pipeline, therefore its shortcoming is, water for fire can't provide, and can not in time utilize the fire plug fire extinguishing when condition of a fire appears in highrise building.
The purpose of this utility model is, provides a kind of and both can eliminate the drinking water secondary pollution, makes each fire plug place that the secondary constant pressure water-supply device of enough hydraulic pressure is arranged again simultaneously.
In order to achieve the above object, the solution that the utility model is taked is, it is directly injected a water tank of usefulness by tap water, the front end water service pipe, the constant pressure water-supply part that water pump and constant-voltage controller constitute, the rear end water service pipe is formed, described front end water service pipe is connected between an above-mentioned water tank and the water pump front end, described rear end water service pipe is connected between the delivery port and each floor water pipe of above-mentioned constant pressure water-supply part, be characterized in, on the water service pipe of described rear end, be communicated with the fire water supply pipe, be provided with two sub-reservoirs that are attached thereto logical automatic control water level in the end of described fire water supply pipe, described two sub-reservoirs are connected with each fire plug by the water for fire efferent duct.
For the ease of maintenance, be preferably in above-mentioned fire water supply pipe and be provided with control valve, the connecting line between above-mentioned rear end water service pipe and each the floor water pipe is provided with valve.Described two sub-reservoirs are a storage tank that comes automatic control water level by float valve preferably.
Because the utility model has adopted said structure, resident's drinking water is directly supplied with by the rear end water service pipe, two sub-reservoir water storage links have been saved, thereby eliminated the secondary pollution of drinking water, again owing to be communicated with the fire water supply pipe at rear end water service pipe place, two sub-reservoirs and fire water efferent duct, be specifically designed to the supply of water for fire, make that the pressure of water for fire is also ensured, therefore its advantage is, resident's water hygiene degree is good, feed pressure is stable, water for fire pressure abundance, both people's drinking water standard can be reached, and the requirement of esidential building fireproof can be met again.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a structural representation of the present utility model.
In structural representation shown in Figure 1, the utility model is made up of with constant pressure water-supply part 5, rear end water service pipe 6 that constant-voltage controller 4 constitutes a water tank 1, front end water service pipe 2, water pump 3 that tap water directly injects usefulness, front end water service pipe 2 is connected between water tank 1 and water pump 3 front ends, and rear end water service pipe 6 is connected between the delivery port and each floor water pipe of constant pressure water-supply part 5.On rear end water service pipe 6, be communicated with fire water supply pipe 8, be provided with two sub-reservoirs, 9, two sub-reservoirs 9 that are attached thereto logical automatic control water level in the end of fire water supply pipe 8 and be connected with each fire plug by water for fire efferent duct 10.In Fig. 1, urbanite water consumption pipe 11 is in each urbanite water consumption pipe, and fire plug 12 is in each fire plug.Above-mentioned fire water supply pipe 8 is provided with control valve 7, and the connecting line between rear end water service pipe 6 and each the floor water pipe is provided with valve 13.Certainly also can be on the rear end water service pipe 6, be provided with corresponding valve on the front end water service pipe 2 and on the tap water pipe line of water tank 1 front end.Two sub-reservoirs 9 are storage tanks that come automatic control water level by float valve.
When two sub-reservoirs 9 by other control mode control water level, as when utilizing control water level such as electromagnetic valve or motor operated valve, when control valve 7, valve 13 and other respective valves are not set on each pipeline, also belong to protection domain of the present utility model.
