Description
Technical field
The utility model relates to architectural design and Drainage Design field of engineering technology, relates in particular to a kind of three form fire cistern systems.
Background technology
Fire cistern and fire water pump house are in the whole building fire protection facility, and most important power source is the heart of whole fire fighting supply facility, in fire extinguishing procedure, in fire water pump house fire cistern, fetch water, and fire pump is transported to the fire-extinguishing apparatus place with water.Total capacity according to standard " Code for fire protection design of high rise buildings " GB50045-95 (version in 2005) 7.3.3 bar regulation fire cistern surpasses 500 ton hours; Should be divided into two fire cisterns that can independently use, the dischargeable capacity of each fire cistern is 1/2 of a total measurement (volume).Reason is for guaranteeing that another still can supply water for fire when cleaning or overhauling a fire cistern.
" fire pump suction water pipe arrangement " is when being two lattice for fire cistern in " the special-purpose water pump of fire-fighting is selected for use and installed " 04S204 (hereinafter to be referred as " atlas ") that China Inst of Architectural Standard Design publishes and " national civil building design technical measures (water supply and drainage) " (version in 2009) (hereinafter to be referred as " measure "); The fire water pump house provides four kinds of arrangements; Wherein scheme one, two, three is selected from " atlas " 11 pages, and scheme four is selected from " measure " 272 pages.
Fire pump (description in the present specification is unified with " atlas ", refers to hydrant pump and spray pump) generally adopts the using and the reserved, and main pump starts automatically during fire, and when main pump was not activated, stand by pump started automatically, and main pump and stand by pump relation can on-the-spotly be set.Fire cistern and pump house arrangement principle are 1. 1 groups of fire pumps, and suction water pipe should not be less than two, when wherein one damage or during maintenance, all the other suction water pipes should still can pass through whole fire consumptions; 2. do not influence the fire pump suction when pond is cleaned; 3. the maintenance of suction line comprises each pipeline section of suction line and valve maintenance; 4. do not consider the valve maintenance when pond is cleaned; 5. do not consider that all water pump is out of order when pond cleaning or pipeline overhaul.
In four kinds of schemes, what scheme one and two adopted is the method for suction cross over pipe, and scheme three has added the pond cross over pipe between two ponds, but it all exists drawback and deficiency:
Scheme one: as shown in Figure 1, when valve middle on the cross over pipe need overhaul, communicating pipe two by-pass valve controls that need close the pond.Two groups of fire pumps are stopped using.
Scheme two: as shown in Figure 2, two suction headers are set between two fire cisterns, automatic water jetting water pump and hydrant water pump suction pipe are connected on respectively on two suction headers.When any one fire cistern cleans, close the valve on communicating pipe, cause one group of pump to quit work.
Scheme three: as shown in Figure 3, with scheme two, between two fire cisterns, water tank connection pipe is set.When any one fire cistern cleans, cause one group of pump to quit work.
Scheme four: as shown in Figure 4, two suction communicating pipes are set between two fire cisterns, every group of suction communicating pipe termination is provided with by-pass valve control.When cleaning the pond, close the by-pass valve control of an end, do not influence four fire pumps and use.When the by-pass valve control on communicating pipe need overhaul and change, need close the by-pass valve control of going up the other end communicating pipe, another communicating pipe can normally use, but the water in a pond needs emptying in two fire cisterns.Communicating pipe can be thought the prolongation of suction pipe line to a certain extent, and suction water pipe increased the right-angled bend of two places, the lengthening of length and turn and certainly will the suction flow velocity and the resistance of suction pipe line be impacted.Adopt when pipeline suction distance is longer when absorbing water communicating pipe, easy to accumulate gas in the pipeline is unfavorable for suction.Suction communicating pipe caliber is very big, and the by-pass valve control size is also very big on communicating pipe, in pump house, is difficult for arranging that floor space is bigger.
In addition; When the various schemes of " atlas " and " measure " adopt communicating pipe to design; Owing to generally connect four pumps (four pumps of two spray pumps of two hydrant pumps are designed to example) at least on communicating pipe; Communicating pipe can be thought the prolongation of suction pipe line to a certain extent, and suction water pipe increased the right-angled bend of two places, the lengthening of length and turn and certainly will the suction flow velocity and the resistance of suction pipe line be impacted.During the fire-fighting fire, hydrant pump and spray pump start simultaneously, and design discharge generally is not less than 70L/s, and the communicating pipe design caliber that causes absorbing water is very big, and by-pass valve control is also very big on communicating pipe, in pump house, is difficult for arranging, also can cause floor space bigger.
