Abstract

The utility model provides a spray nozzle. The appearance of the upper half section is a hexagon prism and the lower half section is in a portal frame structure; a principle that a piston releases pressure and is opened to spray, and an inclined sheet type splash box deflects, splits and atomizes is adopted; a nozzle body and a framework are screwed down by a straight thread; the center of the nozzle body is provided with the piston; the splash box is riveted to the inner side of the top of the framework through a tapered core; pressure is usually maintained through supplementing water at the upper side of the piston and the piston is pressed on a framework sealing seat to be located at a sealed state; the piston is opened through releasing the pressure on the upper side of the piston and a water flow flushes to the tapered core and the splash box; the water flow is deviated and decomposed into mutually-discontinuous fog drop groups to be sprayed and the spray nozzle belongs to the field of fire fighting; the conductive defect caused by that the water flow sprayed by a conventional spray nozzle is decomposed into straight-line continuous fog drop groups through the flat plate type splash box is eliminated and the problem that the spray nozzle cannot be flexibly applied at different points and different regions is solved; the spray nozzle is composed of the nozzle body, the piston, an O-shaped sealing ring, a sealing gasket, the tapered core, the splash box, the framework and a screw; and the spray nozzle has a wide application prospect in a power transformer, a cable tunnel, a cable interlayer, a diesel generating set and the like.

Description

Waterfog head

Technical field

The utility model relates to a kind of for fire protection sector, and the upper semisection profile is hexagon prism, lower semisection is gantry frame structure, adopt vent piston to press off and open spurt, the principle of oblique sheet type splash box shunting atomizing; Current are decomposed into the fine and closely woven droplet group of mutual interruption, spurt by predetermined atomizing angle, be convenient to branch, subregion flexible Application; Belong to fire-fighting fire extinguishing, control fire, fire prevention field.

Background technology

Existing GB GB5135.5-2003 waterfog head does not have piston sealing structure, and spout is open type, open at by-pass valve control, when being filled with press water in the pipe network, waterfog heads all on the pipe network spray together, subregion, branch are used flexibly, and system's water consumption is many, water damage is large.

The splash box of current waterfog head is tabular, and droplet is continuous shape, has electric conductivity; Can not be for the protection of electrical equipment.Such waterfog head can not satisfy the application requirements of power transformer, cable tunnel, cable interlayer, diesel generating set etc.

Summary of the invention

The current that spray in order to solve conventional waterfog head resolve into the continuous droplet group of straight line by flat splash box, and the conduction defective that causes; Can not branch, the problem of subregion flexible Application.The utility model provides a kind of waterfog head, and the upper semisection profile is hexagon prism, lower semisection is gantry frame structure, adopt vent piston to press off and open spurt, the principle of oblique sheet type splash box deflection shunting atomizing; Formed by sprayer body (1), piston (2), O RunddichtringO (3), seal washer (4), cone core (5), splash box (6), framework (7), screw (8); Sprayer body and framework are tightened by straight thread, and piston is equipped with at the sprayer body center, and splash box is riveted on the frame roof inboard by the cone core, and the piston upside is kept pressure by the moisturizing shoulder hole at ordinary times, and piston is pressed on the frame seal seat, makes waterfog head be in sealing state; By the pressure of venting piston upside, piston is opened, and the pressure flow punching is to boring core, splash box, and current deflection is decomposed into the fine and closely woven droplet group of mutual interruption, sprays by predetermined atomization angle, and its area of effective coverage reaches 12 meters ²

The utility model is achieved in that waterfog head is comprised of sprayer body (1), piston (2), O RunddichtringO (3), seal washer (4), cone core (5), splash box (6), framework (7), screw (8).The piston upside is kept pressure by the moisturizing shoulder hole at ordinary times, and piston is pressed on the frame seal seat, makes waterfog head be in sealing state; When action was spurted, by pressure automatic, electronic or manual mode venting piston upside, piston was opened, the pressure flow punching is to boring core, splash box, current deflection is decomposed into the fine and closely woven droplet group of mutual interruption, sprays by predetermined atomization angle, area of effective coverage reaches 12 meters ²After spurting end, close discharge opening by automatic, electronic or manual mode and sluice, piston upside pressure rise, driven plunger moves down, and contacts with the sprayer body seal receptacle to recover sealing.

The beneficial effects of the utility model are: eliminated the current that conventional waterfog head sprays, resolved into the continuous droplet group of straight line by flat splash box, and the conduction defective that causes, having solved can not branch, the problem of subregion flexible Application; Realize repeating to spurt, stop the function of single waterfog head, satisfied easily the logic control requirement that irregular guard plot each point water smoke spurts, reached the control application requirements that cuts off for a plurality of keypoint parts in large guard plot, doorway.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is section of structure of the present utility model.

Fig. 2 is outline drawing of the present utility model.

Fig. 3 is the vital part in the utility model: the sprayer body profile.

Sprayer body: sprayer body is provided with water inlet, pressure relief opening, plunger shaft, and water inlet and plunger shaft, frame seal seat are concentric, and keeps concentric with splash box, cone core; Sprayer body outlet side Excircle machining has straight thread, and the sprayer body end is provided with the groove of setting-in O RunddichtringO.

Splash box: be designed to disc, gear piece is oblique sheet type, and even circumferential is arranged in wavy, changes conventional plate impact straight line and atomizes continuously, for the deflection shunting is interrupted atomizing, has satisfied the insulation application requirement of disc type waterfog head in the electrical fire place that dabble.

The technical scheme in the invention for solving the technical problem is:

Press core component-sprayer body, the splash box of this waterfog head of hydrodynamics three dimensional design, by being provided with water inlet, pressure relief opening, plunger shaft at sprayer body, water inlet and plunger shaft, frame seal seat are concentric, and keep concentric with splash box, cone core; The piston upside is kept pressure by the moisturizing shoulder hole at ordinary times, and piston is pressed on the frame seal seat, makes waterfog head be in sealing state; The pressure of venting piston upside, piston are opened water outlet and are spurted; After spurting end, close discharge opening, piston upside pressure rise, driven plunger moves down, and stops water outlet and spurts, recovers sealing.Realized repeating the function spurting, stop.Splash box is designed to disc, and gear piece is oblique sheet type, and even circumferential is arranged in wavy, has realized injection water, and deflection splits into the droplet group of mutual interruption, has satisfied the insulation application requirement of protection electrical fire.
