Abstract
The utility model discloses a switching device of fire pump water and foamite. The switching device comprises a fluidic device and a control valve, wherein the control valve is communicated with a water output end of a fire pump. The fluidic device comprises a straight pipe segment and a branch pipe segment, wherein the straight pipe segment and the branch pipe segment are mutually communicated. A liquid inlet which is communicated with the control valve is formed at one end of the straight pipe segment, and a connecting pipe which is communicated with the fire pump is installed at the other end of the straight pipe segment. An air chamber which is communicated with the branch pipe segment and a nozzle which is connected with the liquid inlet are formed in the straight pipe segment. The branch pipe segment is communicated with a foamite fluid reservoir through a suction pipe. The switching device can control the water outlet end of the fire pump to spray fire fighting water or foam fire-fighting liquid. The fact that different fire extinguishing agents can be rapidly switched according to different fire sources based on the same fire pump can be achieved. Application field of a single fire pump can be greatly expanded. Whole weight of equipment can be reduced, and fire extinguishing performance is improved.
Description
Technical field
The utility model relates to a kind of switching device shifter, relates in particular to the switching device shifter of fire pump water and fire foam.
Background technology
At present the mode according to the different fire-fighting fire extinguishings of burning things which may cause a fire disaster generally has the various ways such as water pump water outlet fire extinguishing, the fire extinguishing of foam fire pump spray foam, carbon dioxide fire extinguishing, also can be divided into cart type, vehicular, hand according to the difference of size and means of transportation and lift the various ways such as formula.The kind of above-mentioned fire extinguishing, mode all have its inborn limitation, the scope of application is comparatively small-sized, extinguishing property is single, the lane that can't arrive as vehicle under complex environment, mountain forest and burning things which may cause a fire disaster situation be complicated, have fuel oil is unsuitable in the Various Complex situation such as water source fire extinguishing, and traditional extinguishing device all can not be completed the fire extinguishing task effectively, timely.How to provide a kind of and move the good fire pump of energy for burning things which may cause a fire disaster strong adaptability, space, be the object that those skilled in the art study always.
Chinese invention patent application number 01143272.1 discloses a kind of duplex isotactic centrifugal foam fire pump that integrates fire pump, foam pump, pressure air-foam proportioner.Be specially fire pump, foam pump, pressure air-foam proportioner, power transmission box, shaft coupling and dynamic power machine are arranged on same public base, fire pump, foam pump can have different rotating speeds, but can only be dragged by a power source.This kind device has still adopted fire pump, two kinds of pumps of foam pump to realize two kinds of functions, and relative volume, weight are large and be not suitable for the space and move.
Summary of the invention
The utility model provide a kind of energy-saving, high-lift, on the same pump housing output fire pump waters of two kinds of extinguishing chemicals and the switching device shifter of fire foam.
The switching device shifter of a kind of fire pump water and fire foam, described switching device shifter comprise fluidic device and are communicated with the control valve of fire pump discharge end; Described fluidic device comprises straight length and a pipeline section that is interconnected, straight length one end is provided with the inlet that is communicated with control valve, the straight length other end is provided with the tube connector that is communicated with the fire pump water inlet end, and straight length inside is provided with the air chamber of connected component pipeline section and the nozzle that connects inlet; Described pipeline section is communicated with the fire foam fluid reservoir by suction line.Two kinds of extinguishing chemicals of water and fire foam are applicable to different burning things which may cause a fire disaster types, switching by switching device shifter, adopt the different extinguishing chemical of same fire pump output under the prerequisite that does not change fire pump, saved greatly manufacturing cost, improve the scope of application, enlarged the application of the single fire pump of this kind.This kind switching device shifter does not enable fluidic device when cutting out by control valve, fire pump discharge end ejection fire water fire extinguishing, when opening, control valve enters the straight length of fluidic device by control valve by part fire water in fire pump discharge end ejection fire water process, utilize jet current principle to form negative pressure at air chamber, input fire foam by a pipeline section by suction line, then input the water inlet end of fire pump by tube connector, through fire pump mix-froth extinguishing chemical and water, finally at fire pump discharge end ejection foam fire-fighting liquid, realize the switching of two kinds of extinguishing chemicals.
As being provided with flow valve between the preferred suction line of structure and a pipeline section or on a pipeline section, flow valve being set directly, the flow of controlling fire foam is mixed proportion.
The utility model is controlled the ejection fire water of fire pump discharge end or foam fire-fighting liquid by switching device shifter, realization difference according to burning things which may cause a fire disaster on the basis of same fire pump is switched different extinguishing chemicals fast, expanded greatly the application of single fire pump, alleviate the overall weight of equipment, improved extinguishing property.
Description of drawings
Be illustrated in figure 1 as the switching device shifter master TV structure schematic diagram of the utility model fire pump water and fire foam;
Be illustrated in figure 2 as the straight length internal structure schematic diagram of the utility model fire pump water and fire foam.
The specific embodiment
A kind of fire pump water comprises fluidic device 1 and the control valve 3 that is communicated with the fire pump discharge end with the switching device shifter of fire foam as shown in Figure 1, 2, fluidic device 1 comprises straight length and a pipeline section that is interconnected, straight length one end is provided with the inlet 6 that is communicated with control valve 3, the straight length other end is provided with the tube connector 2 that is communicated with the fire pump water inlet end, and straight length inside is provided with the air chamber 7 of connected component pipeline section and the nozzle 8 that connects inlet 6; Prop up pipeline section and be communicated with the fire foam fluid reservoirs by suction line 5.
As being provided with flow valve 4 between the preferred suction line 5 of structure and a pipeline section or on a pipeline section, flow valve 4 being set directly.
