Description

Water jetting machine

The utility model belongs to B05B, and injection apparatus relates to a kind of Water jetting machine.

Injection apparatus is applied in the work such as fire-fighting, cleaning and dispensing agricultural chemicals by wide model.Generally all be provided with fire-fighting equipment in the modern building, for example by rotary hose one termination running water, the fire hydrant that another termination nozzle constitutes; Automatic fire extinguishing system of forming by temperature sensor or Smoke Sensor, warning device and automatic spraying device etc.These devices can be eliminated most of fire of just sending out effectively.But these several equipment have two common shortcomings, the first: when the insufficient pressure at water source (when the multilayer in the skyscraper is enabled fire-fighting equipment simultaneously, the hydraulic pressure deficiency often occurring), the water spray of nozzle distance reduces significantly, the influence fire extinguishing; Its two: the scope of existing equipment water spray is restricted, and leaves the dead angle in building.Also there is the dead angle outdoor in fire brigade when interior of building is sprayed water, be unfavorable for eliminating incipient fire.Be used for the injection apparatus that vehicle cleans, as hydraulic giant, also have this deficiency: hydraulic pressure is crossed when hanging down, and current lack flushing ability, when hydraulic pressure is too high, can damage the paint film of vehicle again.The flusher of agricultural chemicals faces such problem equally: spray power is not enough can produce spray less than the dead angle; Spray power is crossed conference damage crops.

In order to overcome these deficiencies of prior art, the utility model will provide a kind of new water injector, this device should be under the situation of hydraulic pressure deficiency, can be under long distance and bigger dynamics the effective current of ejection, operation such as be beneficial to fire extinguishing or clean, spray insecticide.Simultaneously, it should have bigger and more motor-driven working range, can adapt to the various spaces in building, washing bay or the farmland neatly, to eliminate the water spray dead angle.

The scheme that realizes the foregoing invention purpose is as follows: Water jetting machine, adopt a water-supply-pipe, a termination water source (said water source comprises liquid such as cleaning fluid or agricultural chemicals), another termination nozzle.Unlike the prior art be: the inwall of nozzle is provided with rifling.Said rifling is to use the rifling technology of firearms in the prior art.For example general 32 millimeters home-use calibers can be established 3-7 root rifling, and its degree of depth is the 0.5-3 millimeter; When caliber strengthens, can increase the rifling quantity or the degree of depth.When current when nozzle sprays, because of the effect of rifling, current are along the axis fast rotational of self, the diversity that this rotation reduces current also keeps its more stable directionality, thereby obtains bigger jet length and bigger injection dynamics.In most of the cases, water-supply-pipe is to adopt long delivery hose (for example rubber tube, plastic tube or composite material tube).This Water jetting machine can also be established a water pipe frame, and delivery hose is placed on the water pipe frame.On the water pipe frame, also can be provided with booster water pump, when hydraulic pressure deficiency or the no pressure water source of use, can enable the supercharging of booster pump feedwater flow, can enlarge the scope of application of this apparatus or further strengthen water spray strength.When doing the fire extinguisher use, be to guarantee the water source, this jet fire extinguisher can be provided with two to three water source branched pipes at the front end of water pipe, and each branched pipe connects running water, water tower or water tank respectively.

The Water jetting machine that the utility model provides, can adapt to different hydraulic pressure, under the situation of hydraulic pressure deficiency, nozzle with rifling still can spray effective current, under the normal pressure of general running water, does not enable booster pump, the ejection distance can reach more than 15 meters, though the flow-rate ratio of current is less, impulsive force is bigger, thus be used to put out from the beginning of flame the time than existing sprinkler better effect is arranged.Simultaneously, be placed in delivery hose long on the water pipe frame, can length on demand pull out, move nozzle to place to use, make it have bigger and more motor-driven working range, can adapt to various complex spaces neatly, and eliminate the dead angle.When enabling booster pump, its water spray ability can further be strengthened and can be applicable to no setting-out source.This jet machine also can be used for spraying insecticide and cleaning vehicle except that being used for fire-fighting.When being used to wash automobile, this rotating jet is when producing enough flushing abilities, and is less because of hydraulic pressure, and can not damage paint film on the car.When spraying insecticide, can increase the dispenser distance, the jet of rotation also can make soup be covered with each position of front, reverse side and the plant of blade, improves effect of spraying pesticide.
