Abstract
The invention discloses a tank breathable check valve. The tank breathable check valve comprises a body, and an inner cavity and an outer cavity arranged on the body, wherein a body cover is installed on the body; an inlet is formed on one side of the outer cavity; an inner air inlet is formed at the upper part of the outer cavity; a crash pad and a buoyancy sealed ball which can move freely are arranged in the outer cavity; a sealing seat is arranged at the inner air inlet; a cover plate is arranged below the sealing seat; and a protective cover is arranged above the sealing seat. The tank breathable check valve has the advantages that the body and the body cover are made of aluminum magnesium alloy, and the weight of the tank breathable check valve is 60 percent lower than that of steel products, so that the weight of a ship and the emissions of carbon dioxide are reduced; and the buoyancy sealed ball design is adopted, the sealing operation is light and flexible, the phenomenon of jamming can not occur, the insect preventing and fire preventing cover is arranged above the sealing seat, the sealed ball has buffering effect on the impact force of the sealing seat, and the service life is prolonged.
Description
Technical field
The present invention relates to air duct, cap technical field, be specifically related to the ventilative safety check of a kind of cabin cabinet.
Background technique
Cabinet ventilative safety check in cabin is that we are 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, external form from product, weight, calculate again design after the comprehensive consideration maturation such as performance and purposes, old-fashioned marine air pipe head adopts: 1), the floating drum Seal Design, by the floating drum floating, with the rubber seal seated connection, really sealed, and floating drum positions by the positioning shaft on body, when air pipe head tilts, floating drum and positioning shaft are easy to occur the jam phenomenon, thereby cause floating drum to float, produce air pipe head significant leakage phenomenon, product loses its due performance simultaneously, and the medium of medium and cabin cabinet the inside that causes outside is muddy produces and pollute afterwards together with entering, 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) the flange ventilating mode adopts two limits shuntings to carry out, and each two arcuation bends of two limits, in the product running, producing resistance, 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 my cabin cabinet venting check valve again, make its weight substantially exceed my existing product, the weight on naval vessel is increased simultaneously, and the minimizing of this amount of cargo loading and transporting to the naval vessel ship makes a big impact.
Summary of the invention
The present invention is directed to deficiency of the prior art, cabinet safety check of breathing freely in a kind of cabin is provided.
The present invention realizes by following technological scheme: a kind of cabin cabinet safety check of breathing freely, comprise body and be located at inner chamber, the exocoel on body, body cap is installed on body, exocoel one side is provided with import, top is provided with interior suction port, in exocoel, be provided with antivibration pad, can be freely movable buoyancy ball sealer, interior suction port place is provided with sealing seat.
Wherein, the joint of body and body cap also is provided with sealing gasket, preferably adopts aramid fiber rubber to make.
Wherein, the material of antivibration pad, for adopting nitrile rubber or fluorine rubber, preferably adopts nitrile rubber.
Preferably, below sealing seat, add cover plate, above increase insect protected, fire cover; Material nitrile rubber or the fluorine rubber of sealing seat, preferably adopt nitrile rubber.
Preferably, also be provided with flange connecting hole on the aluminum alloy body, be provided with in flange connecting hole for connecing the flange connecting hole cover of true flange.
Wherein, the flange connecting hole cover preferably adopts polytetrafluoroethylmaterial material to make.
Preferably, the material of body and body cap is stainless 1Cr18Ni9Ti, big gun ZCuSn10Zn2, cast steel ZG235-450 or aluminum-magnesium alloy ZAIMg5Si1, most preferably adopts aluminum-magnesium alloy ZAIMg5S i1.
Preferably, the material of buoyancy ball sealer and protective housing is 1Cr18Ni9Ti or SUS316L.
Preferably, the inside and outside external coating sea water resistance anti-corrosion paint of body and body cap.
Compared with prior art, the body of the ventilative safety check of the cabin cabinet in the present invention and the material of body cap are aluminum-magnesium alloy ZAIMg5Si1,1Cr18Ni9Ti Stainless Steel Products, gunmetal ZCuSn5Pb5Zn5 or cast steel ZG235-450, aluminum-magnesium alloy goods particularly, its weight ratio steel product has reduced 60%, thereby reduces the discharge capacity of ship weight and carbon dioxide; Adopt the design of buoyancy ball sealer, the seal operation light and flexible, not there will be the jam phenomenon, and be provided with protective housing above sealing seat, and ball sealer plays buffer function to the impact force of sealing seat, increases the service life.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1, body; 2, inner chamber; 3, body cap; 4, sealing gasket; 5, protective housing; 6, sealing seat; 7, cover plate; 8, buoyancy ball sealer; 9, antivibration pad; 10, flange connecting hole cover; 11, exocoel.
Embodiment
Below in conjunction with specific embodiment, the invention will be further described.
As shown in Figure 1, a kind of cabin cabinet safety check of breathing freely, comprise body and be located at the inner chamber on body, exocoel, body cap is installed on body, the joint of body and body cap is provided with the sealing gasket of being made by nitrile rubber, exocoel one side is provided with import, top is provided with interior suction port, be provided with by nitrile rubber and make antivibration pad in exocoel, the freely buoyancy ball sealer of activity of being made by 1Cr18Ni9Ti, interior suction port place is provided with the sealing seat of being made by nitrile rubber, add cover plate below sealing seat, top increases the insect protected of being made by 1Cr18Ni9Ti, the protective housing of fire, the body lower end is provided with flange connecting hole, in the aluminium alloy flange attachment hole, be provided with by teflon, made for connecing the flange connecting hole cover of true flange, in addition, in body and body cap, outer surface application sea water resistance anti-corrosion paint.
Working principle of the present invention is: work as oil, oil-feed in the water tank cabinet, during water, cabin cabinet Air can be discharged by ventilative safety check from the cabin cabinet of cabinet air duct upper end, cabin, otherwise the oil in the cabinet of cabin, when water is emitted, air can be come in by the cabin cabinet of cabinet air duct upper end, cabin simultaneously in ventilative safety check supply, make the pressure in the cabinet of cabin keep balance, but when liquid medium is immersed in territory, cabinet venting check valve place, cabin, the buoyancy ball sealer of cabin cabinet venting check valve can stop at the floating function float downward of liquid medium the identical sealing of rubber seal seat on valve, thereby the outside medium can't be entered in the cabinet of cabin, medium in the cabinet of cabin does not cause damage with regard to not polluting.
