Abstract
The utility model relates to an underground stock tank with a float top for a filling station. A tank body is a vertical vessel, an inner float is provided with a float top cover whose shape is similar to an inner cavity of the tank body, and the circumference of the float top cover is fixed with a circle of rubber elastic sealing ring. So the float top cover is contacted with the inner wall of the tank body in elasticity way. The middle part of the bottom of the inner of the tank body is fixedly provided with a supporter, and the height of the supporter is a bit higher than the position of an oil inlet and outlet. Loss by volatilization of the stock tank of the utility model can be reduced, the problem of environment polluted is solved basically, and the manufacture, the mounting, the overhaul, the operation, etc. are all convenient.
Description
The utility model relates to and a kind ofly is used for filling station and some other be embedded in the liquid oil product of underground storing volatile, the normal pressure basin of chemical products.
Existing subterranean tank is horizontal vessel, which is provided with liquid in-out mouth, air extractor vent and metered fuel orifice.Owing to have liquid-vaqor interface and gas-phase space all the time in jar, then the storage product are easy to volatilization, and reservoir capacity is less in addition, and the storage product use and fill frequently in jar, thereby not only storage product air loss is serious, but also cause environmental pollution.
The purpose of this utility model is to provide no liquid-vaqor interface and gas-phase space in a kind of jar, the top storage tanker of floating downward the petrol service station that air loss is little.
Technical solution of the present utility model:
The top storage tanker of floating downward a kind of petrol service station, it includes tank body 1 and cover 2, cover 2 is provided with air extractor vent 3 and metered fuel orifice 4, cover 2 and tank body 1 are tightly connected, the lower end sidewall of tank body 1 is provided with oil inlet 5 and oil outlet 14, it is characterized in that tank body 1 is vertical vessel, float the floating top cover 6 that has to coincide in it with tank body 1 cavity shape, a peripheral intrinsic circle caoutchouc elasticity seal ring 7 of floating top cover 6, make floating top cover 6 become Elastic Contact with the inwall of tank body 1, the intrinsic supporter 8 in lower surface middle part in tank body 1, the height of this supporter 8 is a little more than the position of oil inlet 5 and oil outlet 14.
The utility model adopts vertical floating roof tank structure, and it is about 90% that the air loss of the basin of original same volume is reduced, the also corresponding decline 90% of degree of contaminated environment simultaneously.And, but tank body of the present utility model, cover adopt opening-closing structure, thus make subterranean tank also the same with above-ground tank, have manufacturing, installation, maintenance, advantage such as easy to use, overcome the shortcoming that original subterranean tank is difficult to overhaul.In addition, the utility model has been owing to adopted the angle steel type bolt with flange to connect, the peripheral hardware seal groove structure, make equipment manufacturing, process, use and prevent that seepage is very simple, it is low effective to connect cost than general flange.
Fig. 1 is a structural representation of the present utility model.
As Fig. 1, the utility model all is embedded in below ground, has only top air extractor vent 3, and metered fuel orifice 4 reaches and protrudes upward after hydraulic fluid port 5,14(add an elbow) on the ground.Tank body 1 is preferably drum, and correspondingly floating top cover 6 also is circular.Be connected with a circle angle steel 9 at tank body 1 upper end outer wall, it and tank body 1 upper end outer wall constitute a circle groove, the also intrinsic circle angle steel 10 at the edge of cover 2, the horizontal surface of this circle angle steel 10 just in time falls in the tank body 1 outer wall one circle groove, between angle steel 9 and angle steel 10, be added with one deck seal ring 11, and the vertical surface of the horizontal surface of angle steel 10 and tank body 1 angle steel 9 constitutes a groove again, tank body 1 and cover 2 are tightly connected by bolt at this groove and are one, pour into a mould pitch prill at last again and get final product, can completely cut off earthing water like this and infiltrate in the jar.Only need open cover 2 during maintenance, hanging out floating top cover 6 can carry out.Cover 2 can be flat deck roof, vertex of a cone lid or vault head, if when vertex of a cone lid or vault head, cover 2 must be welded in earlier on the ring flat-plate 15, eliminating the diametral load of tank deck, and then is connected with angle steel 10.The supporter 8 at lower surface middle part can be cylinder in the tank body 1, have the hole on this cylinder perisporium, to be communicated with tank body 1, be connected with some brace panels 12 between cylinder outer wall and tank body 1 inwall, they are dispersion shape and arrange, the intrinsic one deck rubber plate 13 of last ora terminalis face of each brace panel 12 is to reduce the wearing and tearing to floating top cover 6.During operation, earlier oil inlet 5 blind flanges are opened, the RTC unloading pipe is connected with oil inlet 5, open the RTC unloading valve, gasoline enters tank body 1 bottom along oil inlet 5, because the truck tanker upper container is also higher than the highest liquid level in the tank body 1, so under the effect of fluid column static pressure and liquid, floating top cover 6 rises with the liquid level rising of tank body 1, the gas on tank body 1 top is discharged (or suction) by air extractor vent 3, when metered fuel orifice 4 records floating top cover 6 arrival extreme higher positions, stop oil-feed, and shut the blind flange of oil inlet 5 and metered fuel orifice 4.Oil outlet 14 is communicated with oil can, so that refuel a car at any time, at this moment, decline along with oil mass minimizing and liquid level in the tank body 1, floating top cover 6 under the deadweight effect also along with liquid level descends, when recording floating top cover 6 from metered fuel orifice 4 and dropped to extreme lower position, when promptly having rested on the supporter 8, just must in tank body 1, refuel, so move in circles from oil inlet 5.Because during the utility model work, liquid level contacts with floating top cover 6 all the time, thereby reaches the elimination gas-liquid interface, the purpose that reduces storage product air loss and control environment and pollute.
