Abstract
It the utility model is related to a kind of variable-vane Drsplacement hydraulic turbine.At present, fire-fighting technique is also to be improved, fire-fighting fire extinguishing equipment some fields can't efficiently, the application of safety, the foam proportioning unit of such as domestic existing hydrodynamic force driving, the hydraulic turbine used still can not solution never sluice problem.The utility model includes hydraulic turbine housing, it is characterized in that the setting-up eccentricity set in hydraulic turbine housing, the position installation sharf of hydraulic turbine housing bias internal circle center, the both sides of hydraulic turbine housing set flow inlet and outlet, blade is installed, when current pass through the hydraulic turbine, under the power of current on sharf, blade is slided by blade Axial and radial on the circumference of housing, so as to export power on sharf.Variable-vane Drsplacement hydraulic turbine of the present utility model, does not sluice, and relative to the current hydraulic turbine, can save fire fighting supply, reduce the flow of fire-fighting main pump.Variable-vane, current dynamic resistance is small, is not influenceed by pressure of supply water, and range of flow is wide, 400L/min 12000L/min.
Description
Technical field
A kind of fire extinguisher is the utility model is related to automatically reset container valve arrangement.
Background technology
With China's economic sustained and rapid development, overall national strength progressively strengthens the quickening with Process of Urbanization Construction, and at different levels
Great attention of the government to fire-fighting work, country increase year by year to the input of urban fire-fighting equipment, and governments at all levels are used to purchase every year
The expense for buying fire-fighting equipment and goods and materials increases year by year.Meanwhile estimated fire-fighting equipment industry will continue to present soon in the coming years
Fast growth trend, annual growth or is up to 15% to 20%.Start to fire-fighting working depth weight in current governmental and the public
Depending on promotion under, fire-fighting equipment industry future will also keep faster growth rate.At present, fire-fighting technique is also to be improved, disappears
Fire extinguishing equipment some fields can't efficiently, the application of safety, the froth ratio mixing of such as domestic existing hydrodynamic force driving
Device, the hydraulic turbine used still can not solution never sluice problem.
Utility model content
The purpose of this utility model is the problem of presence for prior art, there is provided a kind of variable-vane positive displacement water wheels
Machine, the fire-fighting efficiency of existing fire control technology is improved, and a large amount of sluicing that can be directed to original hydraulic turbine are controlled, and are saved
About fire demand water.
To reach above-mentioned purpose, the utility model adopts the following technical scheme that：A kind of variable-vane Drsplacement hydraulic turbine, bag
Include hydraulic turbine housing, it is characterised in that the setting-up eccentricity set in hydraulic turbine housing, the position of hydraulic turbine housing bias internal circle center
Installation sharf is put, the both sides of hydraulic turbine housing set flow inlet and outlet, install blade on sharf, current pass through water wheels
During machine, under the power of current, blade is slided by blade Axial and radial on the circumference of housing, dynamic so as to be exported on sharf
Power.
The described hydraulic turbine and foam pump is directly connected to by shaft coupling.
The described hydraulic turbine is horizontally or vertically installed on standpipe.
The described hydraulic turbine is aluminium alloy structure or full bronze structures.
Variable-vane Drsplacement hydraulic turbine of the present utility model, does not sluice, and relative to the current hydraulic turbine, can save fire-fighting confession
Water, reduce the flow of fire-fighting main pump.Variable-vane, current dynamic resistance is small, is not influenceed by pressure of supply water, and range of flow is wide, 400L/
min-12000L/min.Positive displacement foam gear pump or high-pressure plunger pump can be coupled in main shaft output power, and foam solution is directly injected into,
Positive displacement matches, and mixing ratio is accurate, it is possible to provide and 3%, 6% adjustable mixed proportion.Structure and principle are simple, no more multi-part,
Mixing ratio is not influenceed by external factors, is equipped with simple pipeline and valve, is easy to clean.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is cross section structure schematic diagram of the present utility model.
Embodiment
With reference to specific implementation case, the utility model is expanded on further.
As depicted in figs. 1 and 2, a kind of variable-vane Drsplacement hydraulic turbine, including hydraulic turbine housing 1, in hydraulic turbine housing
Interior setting-up eccentricity set 2, the position installation sharf 4 of hydraulic turbine housing bias internal circle center, the both sides of hydraulic turbine housing are set
Flow inlet and outlet, blade 3 is installed, when current pass through the hydraulic turbine, under the power of current, blade passes through blade on sharf
Axial and radial slides on the circumference of housing, so as to export power on sharf.The hydraulic turbine and foam pump are direct by shaft coupling
Connection.The hydraulic turbine is horizontally or vertically installed on standpipe.The hydraulic turbine is aluminium alloy structure or full bronze structures.
Utility model works process is as follows：Water from fire-fighting main pump, variable-vane Drsplacement hydraulic turbine is flowed through, due to
Sharf is arranged on skew hydraulic turbine body circle center position, and when current pass through the hydraulic turbine, under the power of current, blade leads to
Cross blade Axial and radial to slide on body circumference, so as to export power on sharf.
The kinetic energy of current is converted into the kinetic energy of sharf, and foam gear pump or high-pressure plunger pump are transferred to by shaft coupling,
Foam gear pump or high-pressure plunger pump conveying foam concentrate liquid are injected into the outlet of variable-vane Drsplacement hydraulic turbine, produce foam and mix
Liquid is closed, because the hydraulic turbine and foam pump are directly connected to by shaft coupling, therefore foam can mix in proportion with water.Foam concentrate liquid
Injection automatically adjusted by the water-carrying capacity for flowing through the hydraulic turbine.Namely bigger by the water of the hydraulic turbine, blade axle speed is faster,
Foam pump conveying foam concentrate liquid is more, and vice versa, and unrelated with pressure of supply water change.
It the above is only preferred embodiment of the present utility model, be not limited to the utility model, it is noted that for
For those skilled in the art, on the premise of the utility model technical principle is not departed from, if can also make
Dry improvement and modification, these improvement and modification also should be regarded as the scope of protection of the utility model.
