For further setting forth the utility model air pressure regulator for the technological means reaching predetermined goal of the invention and take and effect, below in conjunction with accompanying drawing and preferred embodiment, to according to its embodiment of air pressure regulator, structure, feature and the effect thereof that the utility model proposes, be described in detail as follows.
Refer to Fig. 1, the external structure of air pressure regulator mainly comprises housing 1 and jam nut 5 as seen from the figure, and housing 1 has stub end 11 and little head end 12, and little head end 12 connects with jam nut 5, is provided with seal washer 52 in its joint.On housing 1 outer surface, in stub end 11 and little head end 12 joint, be provided with seal ring 113.
Jam nut 5 in use, screws off by this air pressure regulator, takes off seal washer 52, valve body ecto-entad is put into the mounting hole of container wall, by the in-built upper sealing washer 52 of packaging container, screw jam nut 5, make seal washer 52 and seal ring 113 all compress air tight; Then product is loaded packaging box, cover case lid and seal, in case, be filled with nitrogen to certain pressure by the charging air inlet on casing, stop inflation; Namely air pressure regulator is in normal working.
Refer to Fig. 2, the general structure sectional drawing of its utility model embodiment air pressure regulator.As shown in Figure 2, the utility model air pressure regulator has housing 1, it has stub end 11 and little head end 12, and the end face of stub end 11 and inside thereof are all stepped hollow, end face and the inside thereof of little head end 12 are all columnar hollow, stub end 11 has groove 112 with the outer surface of little head end 12 joint, is provided with seal ring 113 in this groove 112.
Be provided with jam nut 5 in the end of the little head end 12 of housing 1, its inside is columnar hollow, and one end end face connected with housing 1 is stepped hollow, and the end face of the other end is provided with pore.The connection of the little head end 12 of housing and jam nut 5 is for being threaded, and little head end 12 surface has outside thread, and jam nut 5 surface has internal thread.In addition, for ensureing this tightness be threaded, tight blind nut 5 has groove 51 on the surface of this joint, is provided with seal washer 52 in groove.
Be provided with axis 2 in the axial direction in the position of housing 1 and the inner middle of jam nut 5, it have boss 21 and groove 22, arranging ring in groove 22 has little back-up ring 23.At adjacent little back-up ring 23, be disposed with packing ring 9, internal partition 8 and large back-up ring 10 near the side, outer end of the little head end 12 of housing, wherein internal partition 8 is provided with pore, and large back-up ring 10 is located in the groove 121 of housing little head end 12 inside.
Inner near stub end 11 side at the little head end 12 of housing, also be provided with bearing 3, it is arranged around axis 2, and has groove 31 in the position relative with the boss 21 on axis 2, be provided with sealing gasket 4 in groove 31, sealing pad connects with the inner chamfer 111 near housing stub end 11.
In addition the utility model air pressure regulator is also provided with two springs, is respectively big spring 7 and little spring 6.It is all columnar design around axis, and wherein one end of big spring 7 is fixed on bearing 3, and the other end is fixed on packing ring 9; One end of little spring 6 is fixed on bearing 3, and the other end is fixed on little back-up ring 23, and two springs are all in compressive state.The both ends of the surface of two springs are vertical with axle of spring through polishing, and the material of spring can select corrosion resistant steel wire.
Refer to Fig. 3, it is the utility model air pressure regulator airtight position partial enlarged drawing.When packaging container internal and external pressure balance, axis 2 is positioned at neutral position; The elastic force that little spring 6 produces oppresses little back-up ring 11, makes it drive the trend of axis 2 oriented jam nut 5 direction movement, thus makes the boss 21 at axis 2 edge be pressed in the plane of sealing gasket 4, envelope of calming the anger in formation A.Meanwhile, the edge of sealing gasket 4 is pressed on the inclined-plane 111 of housing 1 inside by bearing 3 by the elastic force that big spring 7 produces, and forms external pressure sealing gland B; Now air pressure regulator is in two way sealed state.
When packaging container is with non-pressurised freight house air transport or when storing in high altitude localities, external ambient air pressure reduces.When container external and internal pressure difference reaches a timing, the elastic force that the pressure that gas in container is produced by the C plane of stomatal action on axis 2 that jam nut 5 and internal partition 8 are offered will overcome little spring 6 and produces, now axis 2 will move to housing stub end 11 direction, sealing gland A can open automatically, and a part of gas in amount discharge container is with pressure release; When internal tank air pressure is reduced to a certain degree, the elastic force that the underpressure that C plane produces produces to overcome little spring 6, axis 2 moves resile to container inside, and envelope of calming the anger in container A can close again automatically, reaches the balance of container external and internal pressure.
When packaging container returns to low altitude area by high altitude localities, internal tank gas pressure will lower than external ambient air pressure.When container external and internal pressure difference reaches a timing, the stomatal action D plane on axis 2 of container outer air by external partition 14 is offered, the elastic force that the pressure produced will overcome big spring 7 and little spring 6 and produces, bearing 3 is moved to jam nut 5 direction, axis 2 and sealing gasket 4 also move to container inside direction in company with bearing 3 simultaneously, sealing gland B can open automatically, and portion of air can enter in container; When container inner pressure raising makes inside and outside differential pressure be reduced to a certain degree, the elastic force that the underpressure that D plane produces produces to overcome big spring 7 and little spring 6, bearing 3, sealing gasket 4 and axis 2 move to housing stub end 11 direction again and are returned to origin-location, container external pressure sealing gland B can close again automatically, reaches container internal and external pressure balance.
Thus, the utility model air pressure regulator is a kind of bidirectional valve that automatically can regulate container inside and outside differential pressure.When ambient air pressure be reduced to acquire a certain degree with the pressure difference of internal tank air pressure time, the sealing gland of pressure regulator valve inside can be opened automatically, a part of gas in amount discharge container is with pressure release, when internal tank air pressure is reduced to a certain degree, sealing gland can be closed again automatically, thus eliminates " quick-fried case " hidden danger; Otherwise, when ambient air pressure raise be greater than internal tank air pressure to a certain extent time, sealing gland also can be opened automatically, sucks a part of gas to reach the balance of external and internal pressure.
The above, it is only the preferred embodiment of the utility model air pressure regulator, not any pro forma restriction is done to the utility model, although the utility model discloses as above with preferred embodiment, but and be not used to limit the utility model, any those skilled in the art, do not departing within the scope of technical solutions of the utility model, make a little change when the technology contents of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be the content not departing from technical solutions of the utility model, according to technical spirit of the present utility model to any simple modification made for any of the above embodiments, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
