Description
Technical Field
The utility model relates to a floating roof jar does not have oily airtight structure belongs to oil tank seal structure technical field.
Background
At present, for an external floating roof oil tank, in order to ensure that a floating disc can flexibly move up and down, a gap with a certain distance is inevitably formed between the floating disc and the tank wall, so that an annular space with exposed oil surface is formed; the oil in the annular space of this exposed oil level will certainly volatilize, consequently for preventing that oil gas from volatilizing, need seal the setting to the annular space between floating plate and the jar wall.
Today, conventional sealing arrangements commonly take the form of a double seal; the primary sealing means is the direct cover of the oil surface. The commonly used primary sealing mainly comprises three forms of filling type elastic soft sealing, liquid filling type soft sealing and mechanical sealing. In order to guarantee better sealing effect, secondary sealing is arranged outside the primary sealing to form protection of the primary sealing and further reduce oil gas loss.
In the practical application process, a sealing tape with a T-shaped structure is adopted to form a primary sealing chamber and a secondary sealing chamber, and then elastic fillers such as sponge and the like are filled; however, in actual use, the T-shaped integrated structure is inconvenient to assemble and can only be integrally replaced during maintenance, so that the assembly efficiency is reduced, and the use cost is increased.
Disclosure of Invention
An object of the utility model is to overcome the aforesaid not enough, provide a floating roof jar does not have oily airtight structure that assembly efficiency is high and maintain convenient.
The purpose of the utility model is realized like this:
the utility model provides a floating roof jar does not have oily airtight structure, the structure includes the jar wall, floats the dish, bearing plate and scraper blade, and the one end of ring structure's bearing plate is fixed in and floats a top, makes the other end be fixed in on the scraper blade after the face bending of bearing plate, and ring structure's scraper blade closely slides and closes on the jar wall, and primary seal area and secondary seal area enclose in jar wall and the annular space between the dish and close and constitute primary seal space and secondary seal space, all pack in primary seal space and the secondary seal space and have the filler, and the secondary seal space is located primary seal space's top, are provided with spacing hook and clamp plate in this secondary seal space, the top of spacing hook is fixed in the top of floating the dish, and spacing hook is along the outer wall of floating dish down back, the level is outwards extended, spacing hook inlays in the filler in secondary seal space.
The utility model relates to an oil-free air sealing structure of a floating roof tank.A sealing strip is pressed on the outer wall of the top of a floating disc at one end, and the other end of the sealing strip goes down along the outer wall of the floating disc, goes around to the wall of a laminating tank and goes up, returns to the outer wall of the floating disc and goes up and is pressed on the outer wall of the top of the floating disc; the upper end of the secondary sealing belt is fixedly connected to the bottom of the scraper, and the lower end of the secondary sealing belt goes down along the tank wall, then goes around to the outer wall of the attaching floating disc and goes up and is pressed on the top of the floating disc.
The utility model relates to a floating roof jar does not have oily airtight structure, the filler in primary seal space and the secondary seal space is the sponge.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses a sealing strip and secondary sealing strip adopt split type structure to pack fillers such as sponge when being convenient for assemble, and more simple and convenient when later maintenance, reduced use cost.
