Abstract
The utility model discloses a kind of multiplex straight stream nozzle, be characterized in, be made up of upper end hydraulic giant body (7) and lower end hydraulic giant body (4), the bottom of lower end hydraulic giant body (4) is water inlet (5), the top of upper end hydraulic giant body (7) is delivery port (6), middle part has a circle to protrude (9) outward, convergent-divergent body (2) is established in upper end hydraulic giant body (7), the convergent-divergent body (2) of one circle protrusion (9) of corresponding hydraulic giant body (7) middle part, upper end establishes a circle projecting inward (10), in protrusion (10), establishes annular ex-pansion circle (3); Described convergent-divergent body (2) is made up of the shell of two and half Rotary-table shapes, and the top of convergent-divergent body (2) is convergent-divergent delivery port (1); Do not need during use to change various model fire-fighting lance, namely on a kind of fire-fighting lance body of model, can the fire-fighting lance of the various model of scale conversion, thus save time, increase work efficiency, it is easy to operate, simultaneously cost-saving.
Description
Technical field:
The utility model relates to extinguisher technical field, specifically a kind of multiplex straight stream nozzle.
Background technology:
Fire-fighting lance is fire extinguishing appliance water is ejected into effectively on comburant, fire-fighting lance refers to playpipe rifle that carry operation by single or many people, that take water as extinguishing chemical, and fire-fighting lance is divided into according to the difference of pattern and feature: single flow shut-off nozzle and straight stream nozzle; Single flow shut-off nozzle is made up of valve switch, gun barrel and nozzle; Straight stream nozzle is made up of gun barrel and nozzle.Conventional single flow shut-off nozzle and the nozzle diameter of straight stream nozzle have 13mm, 16mm, 19mm tri-kinds, need change the fire-fighting lance of different size model during use according to pattern, have so both delayed the working time to again reduce efficiency.
Utility model content:
The purpose of this utility model is the deficiency overcoming above-mentioned prior art, and provides a kind of multiplex straight stream nozzle; Mainly solve the fire-fighting lance need changing different size model according to pattern when existing fire-fighting lance uses to waste time inefficient problem.
The technical solution of the utility model is: multiplex straight stream nozzle, and its special character is, be made up of upper end hydraulic giant body and lower end hydraulic giant body, the two is threaded; The bottom of described lower end hydraulic giant body is water inlet; The top of described upper end hydraulic giant body is delivery port, middle part has a circle to protrude outward, convergent-divergent body is established in the hydraulic giant body of upper end, the bottom flanging of convergent-divergent body is stuck in the boss bottom the hydraulic giant body of upper end, the convergent-divergent body of one circle protrusion of corresponding hydraulic giant body middle part, upper end establishes a circle projecting inward, in a circle is projecting inward, establishes annular ex-pansion circle; Described convergent-divergent body is made up of the shell of two and half Rotary-table shapes, and the top of convergent-divergent body is convergent-divergent delivery port.
Compared with the prior art multiplex straight stream nozzle described in the utility model has following good effect: do not need during use to change various model fire-fighting lance, namely on a kind of fire-fighting lance body of model, can the fire-fighting lance of the various model of scale conversion, thus save time, increase work efficiency, it is easy to operate, simultaneously cost-saving.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
In order to Comprehension and Implementation better, provide specific embodiment below in conjunction with accompanying drawing and describe the utility model in detail.
Embodiment 1, see Fig. 1, according to design needs, be processed into upper end hydraulic giant body 7 and lower end hydraulic giant body 4, the bottom of lower end hydraulic giant body 4 is water inlet 5, and the top of upper end hydraulic giant body 7 is delivery port 6, and hydraulic giant body 7 middle part, upper end has a circle to protrude 8 outward; The shell of two and half Rotary-table shapes is processed into according to design size, the two is a round table-like shell after merging, i.e. convergent-divergent body 2, convergent-divergent body 2 upper and lower opening, upper end is convergent-divergent delivery port 1, the intermediate member of convergent-divergent body 2 has a circle projecting inward 9, convergent-divergent body 2 is arranged in upper end hydraulic giant body 7, the flanging of its lower end is stuck in the boss bottom upper end hydraulic giant body 7, protrude 8 outside one circle projecting inward 9 of intermediate member and of hydraulic giant body 7 middle part, upper end encloses to match, in a circle projecting inward 9 of convergent-divergent body 2, annular expansion loop 3 is installed; Finally upper end hydraulic giant body 7 and lower end hydraulic giant body 4 are threaded togather, form multiplex straight stream nozzle of the present utility model.
Multiplex straight stream nozzle described in the utility model, during use, according to the needs of fire extinguishing, the various states of adjust flux and jet, while rotating upper end hydraulic giant body, two and half Rotary-table shells of composition convergent-divergent body change, rotate upper end hydraulic giant body in the direction of the clock, convergent-divergent delivery port amplifies, by counterclockwise rotating upper end hydraulic giant body, convergent-divergent delivery port reduces, can at one time in, the fire-fighting lance of different size model need not be changed, adjust required nozzle diameter, which save material, save time, it is easy to operate, play best effort effect.
