Abstract
The utility model relates to a fire monitor, and specifically relates to a variable head of a fire monitor. The variable head of the fire monitor comprises an inner spray pipe and an outer spray pipe sleeved to the inner spray pipe, wherein the rear end of the inner spray pipe is exposed out of the outer spray pipe; a small support is arranged at the exposed part of the inner spray pipe; an L-shaped support is arranged on the outer spray pipe; and the small support is connected with the L-shaped support through an electric push rod. The variable head of the fire monitor further comprises a water flow core arranged at the rear end of the inner spray pipe, a water flow core sleeve for sealing the rear end portion of the water flow core, and a water flow grid arranged in the inner spray pipe, wherein the rear end portion of the water flow core is not closed, a spring is sleeved to the front end portion of the water flow core sleeve, and the rear end portion of the water flow grid is inserted into the water flow core sleeve and fixed by a screw. Compared with the prior art, the variable head of the fire monitor is simple in structure, long in firing range and easy to repair.
Description
Technical field
The utility model relates to a kind of fire monitor, is exactly a kind of fire monitor variable big gun head specifically.
Background technology
Present some domestic fire water monitors, because of the structural relation of big gun head, aloft because both speed differences produce resistance, its range is limited for the current of its ejaculation.
Summary of the invention
The utility model provides a kind of fire monitor variable big gun head in order to overcome the deficiencies in the prior art.
To achieve these goals, the utility model has designed a kind of fire monitor variable big gun head, comprise inner nozzle, and be set in outer nozzle on the inner nozzle, the rear end of inner nozzle exposes to outer nozzle, and be provided with small rack at the exposed parts of inner nozzle, and outer nozzle is provided with L type support, and small rack is connected by electric pushrod with L type support; Also comprise the current core that is arranged on the inner nozzle rear end, the rearward end of current core is what do not seal, and the current core retainer plate that is used for sealing current core rearward end, the sheathed spring of the leading section of current core retainer plate; Also comprise the current lattice that are arranged in the inner nozzle, the rearward end of current lattice is inserted in the current core retainer plate and adopts screw to fix.
Be evenly equipped with through hole on the sidewall on the right side of described current core.
Seal by sealing ring between described current core retainer plate and the current core.
The utility model is compared with prior art, have simple in structure, far firing range, the easily characteristics of repairing.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Referring to Fig. 1,1 is screw; 2 is the current core retainer plate; 3 is spring; 4 is the current core; 5 is outer nozzle; 6 is inner nozzle; 7 is electric pushrod; 8 is handwheel; 9 is the current lattice; 10 is through hole; 11 is sealing ring; 12 is small rack; 13 is L bracket.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, the utility model comprises inner nozzle 6, and be set in outer nozzle 5 on the inner nozzle 6, the rear end of inner nozzle 6 exposes to outer nozzle 5, and has a small rack 12 at the exposed parts of inner nozzle 6, outer nozzle is provided with L type support 13, and small rack 12 is connected by electric pushrod 7 with L bracket 13.Also comprise the current core 4 that is arranged on inner nozzle 6 rear ends, the rearward end of current core 4 is what do not seal, and the current core retainer plate 2 that is used for sealing current core 4 rearward end, the sheathed spring 3 of the leading section of current core retainer plate 2.Also comprise the current lattice 9 that are arranged in the inner nozzle 6, the rearward end of current lattice 9 is inserted in the current core retainer plate 2 and adopts screw 1 fixing.Seal by sealing ring 11 between current core retainer plate 2 and the current core 4 in the present embodiment, be evenly equipped with through hole 12 on the sidewall on the right side of current core 2.
Supply water when spraying, current are by the inner chamber of the groove ingoing stream core 4 around the sealing ring 11, the inner chamber of current core 4 is set up isopiestic state with the end that supplies water, the pretension compression stress that relies on spring 3 overcomes the difference in areas of current core 4 cylindricals and interior circle and the water supply axial force that produces, when pressure of supply water rises to pretightning force greater than spring 3, break away from sealing between current core 4 and the inner nozzle 6 and begin water spray.Electric pushrod 7 can make outer nozzle 6 relative inner nozzles 5 make move left and right, realizes the step-less adjustment of direct current spray jetting, and also rotatable handwheel 8 is realized above-mentioned adjusting not to electric pushrod 7 power supplies the time.
Compare with prior art, have simple in structure, far firing range, the easily characteristics of repairing.
