Fire water monitor is as effective equipment of rescue large-sized fire; Have the reliability height, easy to operate, sensitive performance is high; Characteristics such as long service life are widely used in fire-prone protection zone in one's power, fields such as various inflammable and explosive petroleum chemical enterprises, tank farm, oil transportation harbour, hangar boats and ships.Fire water monitor head is determining the jet length and fire extinguishing effect of water smoke as its key equipment.But there are shortcomings such as jet length is short, the water smoke shape is too disperseed in general fire water monitor head at present, has influenced the fire extinguishing effect.
Summary of the invention
The purpose of the utility model is to provide a kind of fire water monitor head unit, can obtain long jet length and concentrated water smoke shape, and then can improve the fire extinguishing effect of fire water monitor.
In order to achieve the above object, the utility model adopts following technical scheme to be achieved.
A kind of fire water monitor head unit comprises the big gun head mount pad of tubular, and the one of which end connects water pipe; The other end outside is socketed with the inclined-plane spout; The exit portion of said inclined-plane spout is a flared structure, and stretches out outside the big gun head mount pad along water (flow) direction, and said big gun head mount pad inboard is provided with the baffle assembly through the socket support; It is characterized in that; The spout outside, said inclined-plane is socketed with main injection jet along water (flow) direction, and the export department of said main injection jet is disposed with columnar structured and the toroidal structure along water (flow) direction, and said baffle assembly comprises secondary baffle and the leading fluid that sets gradually along water (flow) direction.
The characteristics of the utility model are with further improving:
Said leading fluid is the revolving body of approximate T shape, and the longitudinal section of its guide face is approximate T section, and approximate T section two flanks are camber line, and the port of export tangential direction of its guide face and the elevation angle between the gun barrel cross section are 0 ° ± 15 °.
Form the major flow space between the inner surface of the guide face of said leading fluid and inclined-plane spout.
Said secondary baffle is grouped into by conical section that increases gradually along the water (flow) direction sectional area and trunk portion.Form preparatory diversion space between the inner surface of the outer surface of the conical section of said secondary baffle and big gun head mount pad correspondence.
Be installed in the end of secondary baffle along water (flow) direction after said leading fluid runs through through screw, said leading fluid, secondary baffle are connected with screw thread respectively.
In the fire water monitor head of the utility model, form preparatory diversion space between the inner surface of the outer surface of the conical section of secondary baffle and big gun head mount pad correspondence, form the major flow space between the guide face of leading fluid and the inner surface of inclined-plane spout.Like this, at preparatory diversion space, the resistance the when conical section of secondary baffle has reduced current entering big gun head; And owing to the discharge area reduces in water (flow) direction gradually; Thereby current have been produced a precompressed effect, and be equivalent to increase intake pressure, improved the water inlet flow velocity; After the current of high speed and high pressure got into the major flow space and obtain the pressurization water conservancy diversion of secondary, the water flow jet that forms high speed and high pressure more was to main injection jet; After the release of pressure of main injection jet cylindrical structure quickens the appropriateness diffusion of water conservancy diversion and horn mouth structure, form the concentrated fire extinguishing water smoke of far firing range, shape, thereby reach the purpose of remote fire extinguishing.In addition; After running through through screw, leading fluid is installed in the end of secondary baffle along water (flow) direction; And the secondary baffle of leading fluid is connected with screw thread respectively; Can produce axial displacement through the rotary screw rotation and regulate the distance between leading fluid, the secondary baffle, and then fine setting major flow space.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further explain.
Fig. 1 is the structural representation of a kind of fire monitor big gun head of the utility model;
Among the figure: 1, big gun head mount pad; 2, inclined-plane spout; 3, secondary baffle; 4, main injection jet; 5, leading fluid; 6, screw; 7, major flow space; 8, circlip; 9, socket support; 10, preparatory diversion space.
The specific embodiment
With reference to Fig. 1, be a kind of fire water monitor head of the utility model, comprise the big gun head mount pad 1 of tubular; The one of which end connects water pipe; The other end outside is socketed with inclined-plane spout 2, and the export department of inclined-plane spout 2 is a flared structure, and stretches out outside the big gun head mount pad 1 along water (flow) direction; Spout 2 outsides in inclined-plane are socketed with main injection jet 4 along water (flow) direction, and the export department of main injection jet 4 is disposed with columnar structured and the toroidal structure along water (flow) direction.Big gun head mount pad 1 inboard is provided with the baffle assembly through socket support 9, and the baffle assembly comprises the secondary baffle 3 and leading fluid 5 that sets gradually along water (flow) direction.
Leading fluid 5 is the revolving body of approximate T shape, and the longitudinal section of its guide face is approximate T section, and its two flank is a camber line, and the port of export tangential direction of its guide face and the elevation angle between the gun barrel cross section are 0 ° ± 15 °, and present embodiment is selected 0 ° for use.After running through through screw 6, leading fluid 5 is installed in the end of secondary baffle 3 along water (flow) direction.Leading fluid 5, secondary baffle 3 are threaded with screw 6, can produce axial displacement through rotary screw 6 rotations and regulate the distance between leading fluid 5, the secondary baffle 3.
