Abstract
The utility model discloses a secondary head drainage button panel structure of a breathing regulator with a wedge-shaped block. The circular drainage button panel is additionally provided with five wedge-shaped blocks which are uniformly distributed in a ring shape and have consistent inclination angles and inclination directions. The utility model avoids the phenomenon of gas ejection (FREEFLOW) caused by the passive opening of the water discharge button under the pressure of the two-stage head of the breathing regulator when the breathing regulator encounters strong current. The utility model effectively avoids the FREEFLOW phenomenon of the breathing regulator under the action of water flow, improves the environmental adaptability and safety of the breathing regulator, and has wide application prospect for diving operation with high safety requirement.
Description
Technical Field
The utility model relates to the field of diving equipment, in particular to a two-stage head drainage button panel structure of a breathing regulator with a wedge-shaped block.
Background
With the increasing popularization degree of diving movement, the diving movement also goes to more and more application fields such as underwater rescue, engineering construction, national defense and military and the like from leisure entertainment, scientific investigation and exploration. The diving activities of human beings pursue deeper diving, longer stay and more free activities, and the safety of diving is more important for people. On the basis of more scientific safety rules for making diving activities and more gradual diving adaptability training, engineering technicians continuously improve the safety and reliability of diving equipment, and strive to bring more perfect safety guarantee for diving operators. The water accumulation in the second grade head is got rid of under water to current breathing regulator second grade head for the help diver, has set up the drainage button of push type on the second grade head panel, and when pressing this button, the air inlet of second grade head is opened, and a large amount of air can be from this one-level head entering second grade head, passes through the second grade head gas vent with second grade head water accumulation and discharges. This button must be large enough to be easy to operate (this button is usually integral with the secondary head panel) and sensitive enough to meet the reliability requirements for underwater operation. Thus, another problem is brought, when a diver encounters strong water flow underwater, the drainage button is impacted by the water flow and is easy to malfunction, so that gas is quickly leaked, one gas bottle filled to 200bar can be emptied in a few minutes, and the safety of the diver is threatened fatally. The second grade head drainage button is equally important to the diver, does not have this function, will can't get rid of the interior ponding of second grade head under water, causes drowned, can lead to life danger equally.
There is a need for an improved arrangement that will retain the drain button for its important purpose and avoid the drain button from being mishandled when subjected to high currents.
SUMMERY OF THE UTILITY MODEL
The utility model mainly aims to improve the appearance of a drainage button of a secondary regulator by a wedge-shaped dispersive flow guide (WDI) technology of the secondary regulator, thereby effectively solving the problem of maloperation of the drainage button of the secondary regulator in the background technology when strong current is encountered.
In order to achieve the purpose, the utility model adopts the following technical scheme:
the utility model provides a breathing regulator second grade head drainage button panel structure with wedge, includes circular drainage button panel add five inclination and the consistent wedge of slope orientation that the annular was evenly arranged on circular drainage button panel.
The utility model improves the original circular plane or the secondary head drainage button panel with the plane slightly provided with the circular arc (different brands are slightly different) into a structure that five inclined angles are distributed on the outer circle of the circular plane in a ring shape and the wedge-shaped diversion block faces to the same direction, and is used for dispersing the water flow pressure born by the front face of the secondary head panel and reducing the front impact of the water flow through the turbulent flow area.
After the wedge-shaped dispersive flow (WDI) technology of the secondary regulator is applied, when the drainage button encounters strong current underwater, and water flow acts on the wedge-shaped block, the acting force is decomposed into vertical and horizontal forces due to a certain angle and radian of the wedge-shaped block, which is equal to the reduction of the acting force on the front surface of the drainage button.
After the wedge-shaped dispersive diversion (WDI) technology of the secondary regulator is applied, when the drainage button encounters strong current underwater, and water flow acts on the wedge-shaped block, most of the water flow is guided by the wedge-shaped block due to the fact that the wedge-shaped block has a certain angle and radian, and vortex-shaped turbulent flow is formed above the wedge-shaped block; a small amount of water flow is guided by the wedge-shaped block and flows clockwise along the excircle of the drainage button to form a vortex.
The formation of the turbulent flow zone can disperse the water flow impact on the central area of the button surrounded by the turbulent flow, thereby reducing the stress on the central area of the button.
Compared with the existing structure, the two-stage regulator drainage button panel adopting the two-stage regulator wedge-shaped dispersive flow guiding (WDI) technology has the advantages that when encountering strong current underwater, the impact force borne by the front surface is greatly weakened through the stress decomposition and turbulent flow dispersion of the wedge-shaped block, so that the misoperation of the button is avoided, and the safety of divers encountering extreme conditions underwater is improved.

FIG. 1 is a schematic view of the structure of the present invention.
Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further described with the specific embodiments.
As shown in fig. 1, the water discharging button comprises a circular water discharging button panel, and five wedge blocks 1 which are uniformly arranged in a ring shape and have the same inclination angle and inclination direction are additionally arranged on the circular water discharging button panel 2.
The breathing regulator adopting the wedge-shaped dispersive diversion (WDI) technology of the secondary regulator can greatly weaken the force of water flow received by the drainage button of the secondary regulator when encountering strong water flow underwater by decomposing the stress on the inclined surface of the wedge-shaped block and dispersing the further turbulent flow, so that the elasticity of the spring of the drainage button can not be exceeded, thereby avoiding the misoperation of the button, causing the quick leakage of gas, avoiding the loss of the gas source of a diver underwater due to the misoperation risk, and further causing the drowning safety risk. By applying the wedge-shaped dispersive flow (WDI) technology of the two-stage regulator, the safety of divers in extreme conditions under water is improved, and the wedge-shaped dispersive flow (WDI) technology has extremely high use prospect and application value.
The foregoing shows and describes the general principles, principal features, and principal advantages of the utility model. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the utility model as claimed. The scope of the utility model is defined by the appended claims and equivalents thereof.
