Abstract
The invention discloses a fire control water spraying gun which comprises a spraying cylinder (1) and a gun holder (2), wherein the lower section of the spraying cylinder (1) is connected with the gun holder (2) through a thread, a main water spraying channel (5) is arranged in the spraying cylinder (1) and is communicated with an inner cavity of the gun holder (2), one end, which is connected with the gun holder (2), of the main water spraying channel (5) is a water inlet end (51), the other end of the main water spraying channel (5) is a water spraying end (52), the water inlet end (51) of the main water spraying channel (5) is horn-shaped, and the diameter of an opening of the water inlet end (51) is more than that of an opening of the water spraying end (52). Because the water inlet end of the main water spraying channel is horn-shaped, the water inlet end of the main water spraying channel can be fully fit with the inner cavity of the gun holder, and water can smoothly flow into the spraying cylinder without reflowing so that the spraying range is large.
Description
Technical field
The present invention relates to a kind of fire-fighting equipment, especially relate to a kind of fire-fighting water spraying gun.
Background technology
Fire-fighting lance is the jetting instrument of fire extinguishing, is connected with the water band with it and understands the intensive current of injection, and fire-fighting lance has the advantages such as far firing range, the water yield are large.When fire extinguishing, the fire fighter often uses fire-fighting water spraying gun, forms a lot of network of rivers, controls spreading of the intensity of a fire.The Chinese patent that application number is 201220299726.6 discloses a kind of fire-fighting water spraying gun, by shower nozzle and gun platform, formed, the afterbody of shower nozzle is with connecting cylinder, connecting cylinder has external screw thread, connecting cylinder is threaded with gun platform, inner chamber and the fire protection pipeline of gun platform are connected, be evenly equipped with hole for water spraying on the connecting cylinder barrel, sleeve is nested with outside connecting cylinder and with connecting cylinder and is threaded, the afterbody of shower nozzle also has annular sleeve groove, the sleeve groove is corresponding with sleeve, sleeve is provided with pushing block, pushing block is evenly arranged on the outer wall of sleeve, above-mentioned water pistol not only can put out the fire of fire-fighting lance front, also can put out the fire on the fireman whole body, but due to connecting cylinder with certain thickness, the opening of connecting cylinder end can not be fitted with the inner chamber of gun platform, current are when flowing to the connecting cylinder end, the part current are understood adverse current after bumping against on barrel, affect the flow velocity of current, thereby affect range.
Summary of the invention
The present invention is in order to address the above problem, a kind of fire-fighting water spraying gun that can strengthen the water pistol range is provided, comprise spray canister 1 and gun platform 2, the hypomere of described spray canister 1 and gun platform 2 are threaded connection, have a main jet Aquaporin-5 be communicated with gun platform 2 inner chambers in described spray canister 1, the end that described main jet Aquaporin-5 is connected with gun platform 2 is water inlet end 51, the other end is water spray end 52, the water inlet end 51 of described main jet Aquaporin-5 is tubaeform, and the port diameter of water inlet end 51 is greater than the port diameter of water spray end 52.
Fire-fighting water spraying gun of the present invention, also have some side spray aquaporins 6 on the barrel of described spray canister 1, on the outer wall of described spray canister 1, cover has a slidably regulating sleeve 3, and the front end of spray canister 1 also is provided with a circle front boss 4.
Fire-fighting water spraying gun of the present invention, also be provided with pushing block 7 on described regulating sleeve 3, and the two ends of regulating sleeve 3 also are provided with rubber blanket 8.
Fire-fighting water spraying gun of the present invention, the hypomere of described spray canister 1 is provided with external screw thread, in gun platform 2, is provided with internal thread, by internal thread, with externally threaded, coordinates, and spray canister 1 is connected on gun platform 2.
The invention has the beneficial effects as follows:
The present invention is because the water inlet end of main jet aquaporin is tubaeform, so the water inlet end of main jet aquaporin can fit fully with the inner chamber of gun platform, and current can flow into spray canister glibly, can, toward refluxing, not make range farther.
The accompanying drawing explanation
Examples of the present invention will be described by way of reference to the accompanying drawings, wherein:
Fig. 1 is schematic diagram of the present invention.
The specific embodiment
Disclosed all features in this specification, or the step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.
Disclosed arbitrary feature in this specification (comprising any accessory claim, summary and accompanying drawing), unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is,, unless special narration, each feature is an example in a series of equivalences or similar characteristics.
Fire-fighting water spraying gun as shown in Figure 1, comprise spray canister 1 and gun platform 2, and the hypomere of described spray canister 1 is provided with external screw thread, in gun platform 2, is provided with internal thread, by internal thread, with externally threaded, coordinates, and spray canister 1 is connected on gun platform 2; Have a main jet Aquaporin-5 be communicated with gun platform 2 inner chambers in described spray canister 1, the end that described main jet Aquaporin-5 is connected with gun platform 2 is water inlet end 51, the other end is water spray end 52, the water inlet end 51 of described main jet Aquaporin-5 is tubaeform, the port diameter of water inlet end 51 is greater than the port diameter of water spray end 52, so the water inlet end of main jet aquaporin can fit fully with the inner chamber of gun platform, and current can flow into spray canister glibly, can, toward refluxing, not make range farther.Also have some side spray aquaporins 6 on the barrel of described spray canister 1, on the outer wall of described spray canister 1, cover has a slidably regulating sleeve 3, also be provided with the pushing block 7 of being convenient to fireman's hand push on regulating sleeve 3, the front end of spray canister 1 also is provided with the front boss 4 of a circle for blocking regulating sleeve, and the rear end of regulating sleeve is blocked by the front end of gun platform.When the needs sidewall is sprayed water, regulating sleeve is slipped from the side spray aquaporin, when not needing the sidewall water spray, regulating sleeve is slided to the side spray water channel is covered and gets final product.The two ends of described regulating sleeve 3 also are provided with rubber blanket 8, can avoid because of regulating sleeve the slide spray gun cause and the wearing and tearing of gun platform.
The present invention is not limited to the aforesaid specific embodiment.The present invention expands to any new feature or any new combination disclosed in this manual, and the arbitrary new method disclosed or step or any new combination of process.
