Specific embodiment
A kind of fire-fighting atomizing lance comprising inner sleeve 4 and outer tube 6, the inner sleeve successively include hose transition
2, housing pipe jointing part 15 and water spray portion, integrally formed with multiple anticreep steps 1 on the outer wall of the hose transition, hose connects
Socket part and housing pipe jointing part are separated by being fixed at the postive stop baffle 3 of anticreep step front end, the housing pipe jointing part
Middle part is equipped with external screw thread 16, and externally threaded to be equipped with limit sleeve 14 below, the front end of housing pipe jointing part is fixed with outer tube
Interconnecting piece sealing plate 13, the water spray portion are located at the front end of housing pipe jointing part, and the water spray portion includes water spray casing 11, is located at
Spray water casing rear end water spray portion sealing plate 12 and water spray plug 9 positioned at water spray casing front, set on the water spray casing
There are multiple hole for water sprayings 8, the front of the outer tube is the reducer pipe of reduced diameter and rear portion is equipped with and housing pipe jointing part
The internal screw thread that matches of external screw thread, the outer diameter of the water spray casing is greater than/be equal to outer tube front end internal diameter.
Further, sealing ring 7 is set between the housing pipe jointing part sealing plate and water spray portion sealing plate.
Further, anticreep step is pyramidal structure.
Further, it sprays water the reduced diameter of plug.
Further, mouth 10 is diffused integrally formed with infundibulate water flow in the front end of outer tube.
Further, integrally formed with Anti-slip cover 5 on the outer wall of outer tube.
Further, postive stop baffle and inner sleeve are integrally formed.
Further, limit sleeve and inner sleeve are integrally formed.
It when operation, turns atomization flow down if necessary, turns outer tube backward, make the internal diameter of outer tube and casing of spraying water
Gap between outer diameter is gradually reduced, so that atomization flow be made to be gradually reduced, when outer tube move to its internal diameter just with inner sleeve
Stopping acts when pipe water spray portion sealing plate equal position, and the front end for casing of spraying water at this time is just stuck in the internal diameter of outer tube most
Small place, due to the outer diameter of water spray casing is greater than/be equal to outer tube front end internal diameter, water flow is thoroughly closed, when needing to tune up mist
