Abstract
The utility model discloses a fire water supply system of jointly-used water pump adapters. The fire water supply system of the jointly-used water pump adapters comprises a fire pool (1) arranged in a building, a fire water pump (2) connected with the fire pool, a fire hydrant (4) connected through fire protection pipe networks (3) and the water pump adapters (5) arranged outside the building. The water pump adapters of all branch areas are jointly used, and check valves (6) are additionally arranged between the water pump adapters (5) and the branch area pipe networks (3). Because the water pump adapters of high regions and low regions are jointly used, and the check valves are additionally arranged on all pipelines where all water pump adapters (5) are connected with all branch area pipe networks, the pipe networks of all branch areas are separated, indoor fire protection pumps and pressurizing pumps on a fire fighting truck are also separated and are prevented from generating possible backpressure, pipes and the water pump adapters are saved, and installment and maintenance costs are reduced.
Description
Technical field
The utility model fire-fighting domain relates in particular to a kind of fire supply system of shared siamese connection.
Background technology
High level or super highrise building fire supply system are through regular meeting's subregion; should be greater than 1.0Mpa as hydrant system requirement pressure; automatic sprinkler system should be greater than 1.2Mpa; therefore the vertical division block water system is the technology of generally taking in high level or super highrise building; the subregion of code requirement in fire fighting truck pressure of supply water scope should arrange siamese connection respectively.Because subregion is many, the fire-fighting water yield is big, and the quantity of siamese connection itself is just a lot; Simultaneously for the sake of security, the connector of same subregion, same type often will separate at least two places and arrange, such result is to be connector around the building, and the pipeline that the building interior fire_fighting pipe network links to each other with connector has also had more a lot, causes the installation and maintenance cost to increase.
Summary of the invention
The purpose of this utility model is the defective that exists at above-mentioned prior art, and a kind of fire supply system of shared siamese connection is provided.
The fire supply system of the shared siamese connection that the utility model proposes comprises: be arranged at the fire cistern in the building, the fire pump that is connected with fire cistern, hydrant and a plurality of building siamese connection outward of being located at by the fire_fighting pipe network connection, wherein, the siamese connection of each subregion shares, and adds flap valve between described siamese connection and subregion pipe network.
Compared with prior art, the utility model takes to share the measure of the siamese connection of high low area, the pipeline that links to each other with the subregion pipe network at siamese connection has added a flap valve, the pipe network that has separated each subregion like this, also separate the force (forcing) pump that carries on indoor fire-fighting pump and the fire fighting truck, avoided the issuable back pressure of two class pumps, saved tubing and siamese connection, and the installation and maintenance cost reduces.
Description of drawings
Fig. 1 is the schematic diagram of fire supply system in the prior art;
Fig. 2 is the schematic diagram of the fire supply system after the utility model improves.
The specific embodiment
Below in conjunction with drawings and Examples utility model is described in detail.
Fig. 1 is the schematic diagram of fire supply system in the prior art.The fire fighting system of highrise building requires to satisfy saves oneself and rescues mode outward, generally comprises the fire cistern 1, fire pump 2, fire_fighting pipe network 3 and the hydrant 4 that are arranged in the building.When saving oneself, fire plug 4 is connected to fire branch by fire hose, the water outlet fire extinguishing.Rescuing part outward comprises: be located at the outer siamese connection 5 of building, with the pipeline 7 that is used for being connected the fire_fighting pipe network 3 in the building.When rescuing, utilize water pot and vehicle-mounted water pump on the fire fighting truck outward, be connected with hydrant 4 with fire_fighting pipe network 3 in the building by the outer siamese connection 5 of fire hose and building and pipeline 7.
In the system shown in Figure 1, siamese connection 5 is divided into three subregions with the connection of subregion pipe network, the fire-fighting water yield is 40L/s, each subregion is established three siamese connections 5 and is divided into two groups (one group two, one group one) respectively, amount to nine, 6 groups, each siamese connection need be equipped with corresponding connecting pipe 7.As can be seen, be siamese connection 5 and pipeline 7 around the building among the figure, the pipeline that building interior fire_fighting pipe network 3 links to each other with siamese connection 5 is also a lot, and the installation and maintenance cost is very high.
Fig. 2 is the schematic diagram of the fire supply system after the utility model improves.The fire supply system that the utility model proposes comprises: the hydrant 4 that is arranged at the fire cistern 1 in the building, the fire pump 2 that is connected with fire cistern, connects by fire_fighting pipe network 3, be located at the outer siamese connection 5 of building, with for the pipeline 7 that is connected the interior fire_fighting pipe network 3 of building.Improvement of the present utility model is the measure of taking to share the siamese connection of high low area, and the pipeline 7 that links to each other with subregion pipe network 3 at siamese connection 5 has added a flap valve 6.Utilize the principle of flap valve 6, it is one group that siamese connection 5 integration of each subregion are simplified.Utilize the characteristic of flap valve 6 single water (flow) directions, under the situation that does not influence the fire extinguishing effect that supplies water, saved the many groups of fire department pumper connections that repeat to arrange 5 and corresponding connecting pipe 7 thereof.And the check function of flap valve 6 has separated the water supply of each subregion naturally, do not exist current go here and there mutually the district phenomenon, meet existing NFA code requirement.
As seen from Figure 2, the utility model adopts the technology that shares siamese connection, though increased by 4 flap valve, but the number that can save siamese connection 5 (is illustrated as 6,4 groups), can save the pipeline (be illustrated as 2 times, floor is more high, and it is more obvious to save tubing) that connects past subregion pipe network 3 in a large number from siamese connection 5.
Above-described embodiment only is used for the explanation specific embodiment of the present utility model.Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model design, can also make some distortion and variation, these distortion and variation all should belong to protection domain of the present utility model.
Claims (1)
1. the fire supply system of a shared siamese connection, comprise: be arranged at the fire cistern (1) in the building, the fire pump (2) that is connected with fire cistern, hydrant (4) and a plurality of building siamese connection (5) outward of being located at by fire_fighting pipe network (3) connection, it is characterized in that: the siamese connection of each subregion shares, and adds flap valve (6) between described siamese connection (5) and subregion pipe network (3).
