Abstract
The utility model discloses a light tank ventilation check valve. The light tank ventilation check valve is characterized by comprising a valve body made of aluminum magnesium alloy ZAIMg5Si1 and a valve body cover; the valve body is provided with an inner cavity, an outer cavity and a flange connecting hole; one side of the outer cavity is provided with an inlet, the upper portion of the outer cavity is provided with an inner air inlet, a floating seal ball is arranged in the outer cavity, a rubber seal seat is arranged at the inner air inlet, a protective cover is arranged above the rubber seal seat, and a cover plate is arranged below the rubber seal seat. The valve body and valve body cover of the light tank ventilation check valve are made of aluminum magnesium alloy ZAIMg5Si1 and 1Cr18Ni9Ti, the weight is reduced by 60% as compared with that of steel products, and the weight of a ship and the carbon dioxide emission can be reduced accordingly; by adopting the design of the floating seal ball, sealing operation is facilitated and flexible, and blockage is omitted; a Teflon sleeve is nested in a flange connecting hole to isolate bolts, nuts and a steel flange from connection, and service lives of products are prolonged.
Description
Technical field
The utility model relates to air duct, cap technical field, is specifically related to the ventilative safety check of a kind of lightweight cabin cabinet.
Background technique
The ventilative safety check of cabin cabinet be we according to international advanced innovative technology, in conjunction with warship, bunker oil, the logical exhaust of water tank cabinet and with extraneous medium folder from principle, from the external form of product, weight, calculates design after the comprehensive consideration maturations such as performance and purposes again.1), floating drum Seal Design old-fashioned marine air pipe head adopts:, be connected to seal with rubber seal seat by floating drum floating, and floating drum positions by the positioning shaft on body, in the time that air pipe head tilts, floating drum and positioning shaft are easy to occur jam phenomenon, thereby cause floating drum to float, produce air pipe head significant leakage phenomenon, product loses its due performance simultaneously, and cause the medium of outside and the medium of cabin cabinet the inside muddy enter together with produce and pollute afterwards, serious may produce great consequence; 2) design of two limit vents and insect protected/flame screen is added in the round design of profile soil, makes small product size bigger than normal, and on naval vessel, limited space becomes less, also can cause a lot of inconvenience simultaneously and damage; 3) flange ventilating mode adopts two limits shuntings to carry out, and each two the arcuation bends in two limits, to producing resistance in product running, its flow velocity is reduced, and cabinet stock up speed and effect in cabin is reduced simultaneously; 4) old-fashioned air pipe head material adopts spheroidal graphite cast iron, its wall thickness is thicker than my cabin cabinet venting check valve, and profile is bigger than normal than the ventilative safety check of my cabin cabinet again, make its weight substantially exceed my existing product, the weight on naval vessel is increased simultaneously, and the minimizing of this cargo loading and transporting amount to naval vessel ship makes a big impact.
Summary of the invention
The utility model is for deficiency of the prior art, and cabinet safety check of breathing freely in a kind of lightweight cabin is provided.
The utility model is to realize by following technological scheme: a kind of lightweight cabin cabinet safety check of breathing freely, comprise body, the body cap made by aluminum-magnesium alloy ZAIMg5Si1, body is provided with inner chamber, exocoel, flange connecting hole, exocoel one side is provided with import, top is provided with interior suction port, in exocoel, be provided with the buoyancy ball sealer of being made by 1Cr18Ni9Ti or SUS316L, interior suction port place is provided with rubber seal seat, rubber seal seat top be provided with by 1Cr18Ni9Ti or SUS316L make protective housing, below is provided with cover plate.
Wherein, the joint of body and body cap is also provided with sealing gasket, preferably adopts aramid fiber rubber to make.
Preferably, in flange connecting hole, be provided with the flange connecting hole cover for adpting flange.
Wherein, flange connecting hole cover preferably adopts polytetrafluoroethylmaterial material to make.
Preferably, the inside and outside external coating sea water resistance anti-corrosion paint of body and body cap.
Preferably, in exocoel, be also provided with antivibration pad.
Wherein, the material of antivibration pad, for adopting nitrile rubber or fluorine rubber, preferably adopts nitrile rubber.
Compared with prior art, body and the body cap of the ventilative safety check of cabin cabinet in the utility model are made up of aluminum-magnesium alloy ZAIMg5Si1, and its weight has reduced 60% than steel product, thereby can reduce the discharge capacity of ship weight and carbon dioxide; Adopt the design of buoyancy ball sealer, seal operation light and flexible, there will not be jam phenomenon, and aluminium alloy flange attachment hole should be gone up tetrafluoro cover mutually, to press from both sides from the connection of bolt, nut and steel flange, extends life of product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, body; 2, inner chamber; 3, sealing gasket; 4, protective housing; 5, rubber seal seat; 6, cover plate; 7, buoyancy ball sealer; 8, antivibration pad; 9, body cap; 10, flange connecting hole; 11, exocoel.
Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.
As shown in Figure 1, the ventilative safety check of a kind of lightweight cabin cabinet, comprise body, the body cap made by aluminum-magnesium alloy ZAIMg5Si1, body is provided with inner chamber, exocoel, flange connecting hole, exocoel one side is provided with import, top is provided with interior suction port, in exocoel, be provided with the buoyancy ball sealer of being made by 1Cr18Ni9Ti or SUS316L, interior suction port place is provided with rubber seal seat, rubber seal seat top be provided with by 1Cr18Ni9Ti or SUS316L make protective housing, below is provided with cover plate, is also provided with antivibration pad in exocoel.
Wherein, body and body cap are with bolts, and its joint is also provided with sealing gasket, preferably adopt aramid fiber rubber to make.
In flange connecting hole, be provided with the flange connecting hole cover for adpting flange.
The inside and outside external coating sea water resistance anti-corrosion paint of body and body cap.
Working principle of the present utility model is: work as oil, oil-feed in water tank cabinet, when water, in the cabinet of cabinet cabin, cabin, air can be discharged from the ventilative safety check of the cabin cabinet of cabinet air duct upper end, cabin, otherwise when the oil in the cabinet of cabin, when water is emitted, air can be come in by the cabin cabinet venting check valve supply of cabinet air duct upper end, cabin simultaneously, make the pressure in the cabinet of cabin keep balance, but in the time that liquid medium is immersed in territory, the ventilative safety check place of cabin cabinet, the buoyancy ball sealer of the ventilative safety check of cabin cabinet can stop the identical sealing of rubber seal seat on valve at the floating function float downward of liquid medium, thereby outside medium cannot be entered in the cabinet of cabin, medium in the cabinet of cabin just can not pollute and cause damage.
The foregoing is only the preferred embodiment that embodies the utility model principle, therefore do not limit protection domain of the present utility model, within every equalization of doing according to the utility model changes the scope of the claims of all containing at the utility model with modification.
