Abstract
The utility model discloses a fire water branch. The fire water branch comprises a water inlet section, a cavity and a spray nozzle section, wherein the water inlet section, the cavity and the spray nozzle section are connected in sequence; the inner cavity of the water inlet section is gradually narrowed down from a water inlet end to a water outlet end; the cavity is a curved surface; and an inwards concave tapered surface is formed on the part connecting the curved surface with the spray nozzle section; the water inlet section and the spray nozzle water are revolving bodies surrounding the same axis; the centre line of the cavity is collinear with the axis of the water inlet section and the spray nozzle section; a reducing plate is arranged on the spray nozzle section; and the reducing plate is arranged at a spray hole of the spray nozzle section by a clamping device. A firefighter can adjust the size of the water column at any time according to the specific conditions of fire, so that the water outlet amount is controlled to satisfy the practical fire extinguishing needs of the firefighter.
Description
Technical field
The utility model relates to a kind of fire-fighting equipment, relates in particular to a kind of fire-fighting lance.
Background technology
In fire-fighting domain, fire hydrant and fire fighting truck fire extinguishing are common fire-fighting modes, using the fire extinguishing of fire hydrant or fire fighting truck is all that water pipe is connected with fire fighting truck or fire hydrant, then connect fire-fighting lance in the other end of water pipe, use the purpose of fire-fighting lance both can further increase the pressure of water, make the farther of water spray, can allow simultaneously water form water smoke, reach so very large fire extinguishing scope, just can realize large-scale fire extinguishing with a small amount of water, so the effect of fire-fighting lance is particularly important in fire-fighting domain.
Existing fire-fighting lance nozzle diameter size is certain, in the situation that the constant water column size that forms of hydraulic pressure can not change, the fire fighter can not regulate according to the concrete condition of the intensity of a fire size of water column, can only control by the size of controlling hydraulic pressure, controls very inconvenient.
The utility model content
In order to overcome defects, the utility model provides a kind of fire-fighting lance, and the fire fighter can regulate the size of water column at any time according to the concrete condition of the intensity of a fire, thereby controls water yield, satisfies the fire extinguishing needs of fireman's reality.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
Fire-fighting lance, comprise that the inlet segment, cavity and the nozzle segment that connect successively form, it is characterized in that: the inner chamber of described inlet segment by water inlet end to the water side constriction gradually, described cavity is curved body, and the position that this curved body is connected with nozzle segment is provided with the conical surface of indent, described inlet segment and nozzle segment are the revolving body around the same axis line, the axis conllinear of the center line of described cavity and inlet segment and nozzle segment, described nozzle segment is provided with the reducing sheet, and this reducing sheet is arranged on the spray orifice of nozzle segment by clamping device.
Radially be disposed with the circular hole that the aperture diminishes gradually on the axis of described reducing sheet.
Be bonded with sealing strip in described clamping device.
The utlity model has following advantage:
The utility model due to the inner chamber of inlet segment by water inlet end to the water side constriction gradually, cavity is curved body, and the position that this curved body is connected with nozzle segment is provided with the conical surface of indent, inlet segment and nozzle segment are the revolving body around the same axis line, and the axis conllinear of the center line of described cavity and inlet segment and nozzle segment makes water under high pressure through inlet segment, cavity and nozzle segment the time, make hydraulic pressure in the situation that constant, range enlarges markedly, and it is strong that anti-air stream tears ability, can not fall earthward halfway.At nozzle segment, the reducing sheet is set, this reducing sheet is arranged on the spray orifice of nozzle segment by clamping device, clamping device is clamped in the reducing sheet spray orifice of nozzle segment, effect by the reducing sheet, the fire fighter can come according to the concrete condition of the intensity of a fire size of Control Nozzle section spray orifice, thereby control the size of discharge, satisfy fire fighter's fire extinguishing demand.Adhering and sealing bar in clamping device, anti-sealing causes the damage of fire-fighting lance from the clamping device side leakage.

The specific embodiment
As shown in Figure 1, fire-fighting lance, comprise that the inlet segment 1, cavity 2 and the nozzle segment 3 that connect successively form, it is characterized in that: the inner chamber of described inlet segment 1 by water inlet end to the water side constriction gradually, described cavity 2 is curved body, and the position that this curved body is connected with nozzle segment 3 is provided with the conical surface of indent, described inlet segment 1 and nozzle segment 3 are the revolving body around the same axis line, the axis conllinear of the center line of described cavity 2 and inlet segment 1 and nozzle segment 3, described nozzle segment 3 is provided with reducing sheet 5, and this reducing sheet 5 is arranged on spray orifice 4 places of nozzle segment 3 by clamping device 6.
Radially be disposed with the circular hole that the aperture diminishes gradually on the axis of described reducing sheet 5.
Be bonded with sealing strip in described clamping device 6.
The utility model due to the inner chamber of inlet segment by water inlet end to the water side constriction gradually, cavity is curved body, and the position that this curved body is connected with nozzle segment is provided with the conical surface of indent, inlet segment and nozzle segment are the revolving body around the same axis line, and the axis conllinear of the center line of described cavity and inlet segment and nozzle segment makes water under high pressure through inlet segment, cavity and nozzle segment the time, make hydraulic pressure in the situation that constant, range enlarges markedly, and it is strong that anti-air stream tears ability, can not fall earthward halfway.At nozzle segment, the reducing sheet is set, this reducing sheet is arranged on the spray orifice of nozzle segment by clamping device, the handstand door font device that clamping device is comprised of 3 bar section of stainless steel that are fixed on spray orifice, clamping device is clamped in the reducing sheet spray orifice of nozzle segment, effect by the reducing sheet, the fire fighter can come according to the concrete condition of the intensity of a fire size of Control Nozzle section spray orifice, thereby controls the size of discharge, satisfies fire fighter's fire extinguishing demand.
