Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a fire extinguisher nozzle, includes connecting piece 1, the 1 left and right sides of connecting piece all is provided with the external screw thread, 1 right side threaded connection of connecting piece has base 2, 2 one end threaded connection of base has honeycomb duct 3, honeycomb duct 3 falls into two and cuts, the protrusion is provided with screw thread 5 in the middle of honeycomb duct 3 first section, the junction cover that honeycomb duct 3 two cut has packing ring A6, honeycomb duct 3 second is cut and has been seted up 4 apopores 7, honeycomb duct 3 second is cut one pot head and has packing ring B8, the cover has sleeve 4 on the honeycomb duct 3, sleeve 4 corresponds packing ring A6 with the region between the packing ring B8, its the diameter of sleeve 4 inner wall by the diameter of packing ring A6 reduces gradually into the diameter of packing ring B8, manger plate 10 does not stretch out the horn mouth. The right end of the second section of the draft tube is provided with a connecting column 9, the right end of the connecting column is provided with a water retaining sheet 10, and the first section diameter of the draft tube 3 is larger than the second section diameter of the draft tube 3; the draft tube 3 is sleeved with a sleeve 4, the sleeve 4 is in threaded connection with the first section corresponding part of the draft tube 3 through the screwing thread 5, the diameter of the inner wall area of the sleeve 4, through which the gasket A6 slides, is the same as that of the gasket A6, the maximum diameter of the water retaining sheet 10 is smaller than that of the water outlet at the right side of the sleeve 4, and the water outlet at the right side of the sleeve 4 is connected with a bell mouth.
As shown in fig. 2, when using, install this fire extinguisher nozzle on spray gun 11, unscrew sleeve 4, gasket B8 and the 4 delivery ports separation of sleeve this moment, when spray gun 11 sprays water, rivers pass through connecting piece 1 in proper order, base 2, honeycomb duct 3, and spout from apopore 7, the spun water is followed and is dispersed between gasket B8 and the sleeve 4 and discharge, because breakwater 10 stretches out the delivery port, because water is from delivery port blowout spliced pole 9 and breakwater 10, thereby the rivers change conveniently and reflect to form the splash on the bellmouth inner wall again, water spun shape is vaporific in gondola water faucet this moment, the condition that the backward flow then appears in the gasket A6 of rear side avoids rivers.
In the unscrewing process, the water mist gradually changes into water spray and then becomes a water column, and the water flow gradually becomes larger.
Continuing to unscrew the sleeve 4, as the splash plate 10 retracts from the bell mouth to the water outlet, now forming a water column, the water flow forming the water column becomes smaller, but the throw is furthest because it is the time when the water column is formed when the gap between the gasket B8 and the inner wall of the sleeve is the smallest.
Continuing to unscrew the sleeve 4, when the washer B8 is rotated to the position of the washer a6 when the nozzle is closed, the gap between the washer B8 and the inner wall of the sleeve 4 is maximized, and the sprayed water is maximized and the range is far.
On continued unscrewing of the sleeve 4, the gap between the washer B8 and the inner wall of the sleeve 4 does not change, and at this time the washer B8 is located within the range of the movement region of the washer a6 of the sleeve 4, so the gap between the washer B8 and the inner wall of the sleeve 4 does not change.
And the stroke of the whole sleeve 4 movement is in a closed state when the gasket B8 is coincident with the sleeve water outlet, and other gradual change strokes are completed by matching the screwing thread 5 convexly arranged in the middle of the first section of the draft tube 3 with the corresponding screwing thread 5 matched with the sleeve 4, so that the adjustment of the integral water column distance and the adjustment of the water mist and the water spray size are realized.
After use, the cart-based water-based fire extinguisher 12 can be closed and the sleeve 4 can be tightened, and the water outlet of the sleeve 4 is blocked by the gasket B8 after the sleeve 4 is tightened, so that the nozzle is sealed.
As shown in FIG. 3, the nozzle of the fire extinguisher is threadedly coupled to a spray gun 11 of a cart type water-based fire extinguisher 12, and the fire extinguisher includes a hose detachably coupled to the cart type water-based fire extinguisher 12, and also includes the nozzle detachably coupled to the hose.
