Abstract
A positive pressure oxygen respirator breathing chamber is composed of a circular hard outer wall with a breathing hose connector, a corrugated air bag group, a partition plate group and a loading spring, wherein the partition plate group is fixed in the middle of the inside of the circular hard outer wall with the breathing hose connector and is divided into an upper part and a lower part, the corrugated air bag group is fixed at the opening end of the circular hard outer wall with the breathing air bag hose connector, so that the breathing chamber is an independent closed space, one end of the loading spring is positioned by using the outer diameter of an exhaust valve, and the other end of the loading spring is fixed on a shell by using a screw.
Description
The utility model belongs to a kind of positive-pressure type mechanism that positive pressure oxygen respirator is realized the malleation principle.
Existing oxygen breathing apparatus all belongs to domestic suction type structural principle, and its shortcoming is that air-breathing, automatic supply is all worked under negative pressure condition on main breathing technique index, and is lower than the protection coefficient with the positive-pressure type oxygen breathing apparatus, poor safety performance; The BIOPAM-240 volume that the external oxygen breathing apparatus such as the U.S. produce is big, quality heavy, complex structure, the firstth, the volume of breathing the storehouse is bigger, complex structure, and breathing bag is with the large diameter structure of single ripple, give other the part manufacturing, increased very big difficulty in the technology, forming process, and manufacturing cost is bigger; The BG4EP complex structure that Germany Drqger company produces, electronic installation is more, and is incompatible at underwater work.
The purpose of this utility model provide a kind of simple in structure, volume is little, light weight, easy to assembly, easy to manufacture, cost is low, can breathe the storehouse at the positive pressure oxygen respirator of underwater work.
The purpose of this utility model is achieved in that the assembling of ripple air bag group and connecting mode are: liner plate (7) is packed in the ripple air bag (6), with rivet with liner plate (7) and ripple air bag (6) riveted and fixed, again the air bleeding valve (5) that assembles is utilized the helicitic texture of air bleeding valve (5) itself to connect with the ripple air bag that riveted joint finishes, at last three support rings (11) are put into the crest of ripple air bag, with quantitative oxygen supply valve (8), automatically oxygen supply valve (9) connects with the automatic replenishing valve seat with helicitic texture respectively, after connection finishes, be screwed on dividing plate, make it become dividing plate group (3), after the dividing plate group (3) that assembles being screwed on the reference column of pars intramuralis outside having the circular hard of tidal air hose connection, utilize the steel restraint zone to be fixed on ripple air bag group (2) to have the openend of the circular hard outer wall of tidal air hose connection again, loading spring (4) one ends utilize the external diameter location of air bleeding valve (5), and an end utilizes screw to be fixed on the shell of product.
The breathing storehouse of this structure has that volume is little, simple in structure, and dischargeable capacity is big, make assembling easily, low, the handling characteristics of can in water, meeting an urgent need of cost.
Concrete structure of the present utility model by following enforcement just and accompanying drawing provide.
Fig. 1 is a structural representation of the present utility model.
1, the circular hard outer wall 2, ripple air bag group 3, dividing plate group 4, loading spring 5, air bleeding valve 6, ripple air bag 7, liner plate 8, quantitative oxygen supply valve 9, automatic oxygen supply valve 10, dividing plate 11, the support ring that have the tidal air hose connection
Ripple air bag group 2 is by air bleeding valve 5, ripple air bag 6, liner plate 7, support ring 11 is formed, at first liner plate 7 is packed in the ripple air bag 6 then with rivet liner plate 7 and ripple air bag 6 riveted and fixed, again the air bleeding valve 5 that assembles is utilized air bleeding valve 5 helicitic textures own to connect with the ripple air bag that riveted joint finishes, at last three support rings 11 are put into the crest of ripple air bag, dividing plate group 3 is by timing oxygen supply valve 8, automatic oxygen supply valve 9, dividing plate 10 is formed, its connecting mode is with quantitative oxygen supply valve 8, automatically oxygen supply valve 9 connects with the automatic replenishing valve seat with helicitic texture respectively, after connection finishes, be screwed on dividing plate, at last the dividing plate group 3 that assembles is screwed after on the reference column of circular hard outer wall 1 inside that has the tidal air hose connection, utilize the steel restraint zone to be fixed on ripple air bag group 2 to have the openend of the circular hard outer wall 1 of tidal air hose connection again, loading spring 4 one ends utilize the external diameter location of air bleeding valve, and an end utilizes screw to be fixed on the shell.
The breathing storehouse of this structure is when carrying out work, oxygen at first flows into the top of breathing the storehouse by the quantitative oxygen supply valve that is fixed on the dividing plate group during suction condition, pod apertures on dividing plate flows into the bottom of breathing the storehouse then, just form a force value in breathing inside, storehouse like this, begin to move downward in (under the situation of this pressure) ripple air bag group under the effect of this pressure greater than loading spring power, after the air-breathing beginning, because the pressure of breathing in the storehouse descends, ripple air bag group begins again to move upward under the effect of loading spring power, and desired gas flows out through the inhaling hose interface; During expiration, the gas of exhalation enters the bottom of breathing the storehouse through the expiration hose connection, makes to breathe storehouse pressure inside increase, and ripple air bag group moves downward, and when internal pressure reached certain value, air bleeding valve began unnecessary gas is discharged.
Gas pressure in whole tidal air process in the breathing storehouse is combined with the motion of architectural characteristic of breathing the upper and lower air chamber in storehouse and ripple air bag by loading spring and remains malleation.
Claims (1)
1, a kind of positive pressure oxygen respirator is breathed the storehouse, is made up of the circular hard outer wall (1) that has the breathing hose interface, ripple air bag group (2), dividing plate group (3), loading spring (4), it is characterized in that:
The assembling and the connecting mode of A, ripple air bag group are: liner plate (7) is packed in the ripple air bag (6), with rivet with liner plate (7) and ripple air bag (6) riveted and fixed, again the air bleeding valve (5) that assembles is utilized the helicitic texture of air bleeding valve (5) itself to connect with the ripple air bag that riveted joint finishes, at last three support rings (11) are put into the crest of ripple air bag
B, with quantitative oxygen supply valve (8), automatically oxygen supply valve (9) connects with the automatic replenishing valve seat with helicitic texture respectively, after connection finishes, be screwed on dividing plate, make it become dividing plate group (3), after the dividing plate group (3) that assembles being screwed on the reference column of pars intramuralis outside having the circular hard of tidal air hose connection, utilize the steel restraint zone to be fixed on ripple air bag group (2) to have the openend of the circular hard outer wall of tidal air hose connection again
C, loading spring (4) one ends utilize the external diameter location of air bleeding valve, and an end utilizes screw to be fixed on the shell.
