Abstract
The invention belongs to the field of fire fighting, relates to high-pressure water mist fire fighting equipment and discloses a gas-liquid dual-phase mixer. The gas-liquid dual-phase mixer comprises a three-way body and a liquid boosting shower nozzle connected to the three-way body, wherein the three-way body comprises a mixing pipe cavity as well as a gas inlet passage and a liquid outlet passage which are respectively connected with the mixing pipe cavity; and the liquid boosting shower nozzle extends into the mixing pipe cavity and is coaxial with the liquid outlet passage.
Description
Technical field
The invention belongs to the fire-fighting fire extinguishing field, relate to the heavy pressure fine spray fire-fighting equipment, be specifically related to a kind of gas-liquid bipolar mixture device.
Background technology
Two-phase formula high-pressure fine spray extinguisher is a kind of novel fire-extinguishing apparatus, and its action principle is to utilize gases at high pressure (N
2) liquid in the tank (water) is pressed into fire protection pipeline, fire water is fully mixing with gas, at last through the laggard zone of going into to put out a fire of atomizer, thereby characteristics such as by absorbing the purpose that oxygen content around calory burning and the dilute combustion thing reaches fire extinguishing, that the fire-fighting mode of this device has is nontoxic, pollution-free, high-efficiency cleaning.
But the fluid motion rule of gas, liquid mixture is comparatively complicated, and whether the gas-liquid bipolar mixture device design in the two-phase fine spray extinguisher has rationally just directly determined the reliability of whole system.The gas-liquid bipolar mixture device that uses in the present two-phase high-pressure water mist fire-extinguishing equipment exists gas-liquid mixed than shortcoming such as inaccurate, that two-phase pressure is unbalanced, even the situation that the air-flow blocking-up extinguishing fluid of elevated pressures flows out, the effect of influence fire extinguishing may occur.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind of gas-liquid bipolar mixture device, can balanced gas-liquid two-phase pressure, stablize the gas-liquid mixed ratio, prevent air-flow blocking-up extinguishing fluid stream, effectively improve the reliability of a whole set of heavy pressure fine spray system.
In order to achieve the above object, the present invention is achieved by the following technical solutions.
A kind of gas-liquid bipolar mixture device is characterized in that, comprises the threeway body, and the liquid supercharging shower nozzle that connects the threeway body; Described threeway body comprises and mixes tube chamber and be communicated with inlet channel and the liquid outlet channel that mixes tube chamber respectively; Described liquid supercharging shower nozzle stretches into described mixing tube chamber, and coaxial with liquid outlet channel.
Further improvement of the present invention and characteristics are:
Described mixing tube chamber is coaxial with liquid outlet channel, and the diameter of mixing tube chamber is greater than the liquid outlet channel diameter.
Described liquid supercharging shower nozzle has horn-like contraction structure.
Among the present invention, its threeway body comprises and mixes tube chamber and be communicated with inlet channel and the liquid outlet channel that mixes tube chamber respectively, liquid supercharging shower nozzle stretches into the mixing tube chamber, and it is coaxial with liquid outlet channel, can improve to enter by liquid supercharging shower nozzle and mix intraluminal fluid pressure, can stablize the gas-liquid mixed ratio, prevent air-flow blocking-up extinguishing fluid stream, effectively improve the reliability of a whole set of heavy pressure fine spray system.
Simultaneously, it is coaxial with liquid outlet channel to mix tube chamber, and the diameter that mixes tube chamber helps the gas-liquid bipolar mixture greater than the liquid outlet channel diameter, and helps reducing the fluid pressure loss, the outlet pressure of assurance liquid outlet channel; Liquid supercharging shower nozzle has horn-like contraction structure, and it is simple in structure, and cost is low.
In addition, the present invention is simple in structure, easy for installation, reliability is high, easy to maintenance.
Description of drawings
Following accompanying drawing is described in further detail structure of the present invention and operation principle.
Fig. 1 is a structural representation of the present invention;
Wherein: 1, threeway body; 101, liquid outlet channel; 102, mix tube chamber; 103, inlet channel; 201, horn-like contraction structure; 202, feed pathway.
The specific embodiment
Referring to Fig. 1, a kind of gas-liquid bipolar mixture device of the present invention mainly comprises threeway body 1, and the liquid supercharging shower nozzle that connects threeway body 1.Wherein, threeway body 1 comprises and mixes tube chamber 102, and is communicated with inlet channel 103 and the liquid outlet channel 101 that mixes tube chamber 102 respectively; Inlet channel 103 vertical connection mixing tube chambers 102 mix tube chamber 102 and liquid outlet channel 101 horizontal coaxial arrangement, and mix the diameter of the diameter of tube chamber 102 greater than liquid outlet channel 101.Liquid supercharging shower nozzle has feed pathway 202 and horn-like contraction structure 201, and horn-like contraction structure 201 stretches into and mixes tube chamber 102, and is bolted to connection threeway body 1.
Operation principle of the present invention is: when high-pressure water mist fire-extinguishing equipment moves, water in the tank, after the high pressure nitrogen pressurization, feed feed pathway, spray into the mixing tube chamber through horn-like contraction-like structure supercharging, after high pressure nitrogen in the inlet channel fully mixes in tube chamber, go forward side by side into the fire extinguishing tube road from the liquid outlet channel ejection.
Although below in conjunction with the accompanying drawings embodiment of the present invention are described, the present invention is not limited to above-mentioned specific embodiments and applications field, and above-mentioned specific embodiments only is schematic, guiding, rather than restrictive.Those of ordinary skill in the art under the situation that does not break away from the scope that claim of the present invention protects, can also make a variety of forms under the enlightenment of this specification, these all belong to the row of the present invention's protection.
Claims (3)
1. a gas-liquid bipolar mixture device is characterized in that, comprises the threeway body, and the liquid supercharging shower nozzle that connects the threeway body; Described threeway body comprises and mixes tube chamber and be communicated with inlet channel and the liquid outlet channel that mixes tube chamber respectively; Described liquid supercharging shower nozzle stretches into described mixing tube chamber, and coaxial with liquid outlet channel.
2. gas-liquid bipolar mixture device according to claim 1 is characterized in that described mixing tube chamber is coaxial with liquid outlet channel, and the diameter of mixing tube chamber is greater than the liquid outlet channel diameter.
