Description
Technical field
The utility model relates to a kind of sealing arrangement, particularly a kind ofly at the liquid level instrument is installed opening on the aluminium floating plate is implemented the leak free sealing arrangement in petrol storage tank, belongs to oil tank monitoring technique field.
Background technology
The liquid of being stored in the petrol storage tank is generally effumability liquid, as gasoline, ethanol etc.The liquid of this effumability, when air of its surface contact did not reach certain concentration, the volatilization that this liquid will continue became gas by liquid, and after the gas (oily vapour) on surface reaches finite concentration, medium will progressively stop volatilization.
In actual industrial realized, the lasting volatilization of this oily vapour brought a large amount of losses and economic loss can for the storage of petrochemical industry.There is data statistics to show, 24 hours volatilizable 5.184 kilograms of gasoline in gasoline surface of every sq m area.Moreover, ethereal oil vapour still is flammable dangerous material.When oily vapour reaches finite concentration, meeting naked light will explode and burn, and control oily vapour and volatilize, be the important safety safeguard work of relevant unit.Simultaneously, oily vapour volatilization causes the environmental ambient air gross pollution, and plant growth is affected, and soil, water source are polluted, the life that influence is human.
The problem that the volatilization of oily in view of the above vapour is brought, people realize sealing to fluid by the mode that floating plate is set at the fluid upper surface.Wherein, a kind of more common floating plate mode is an aluminium floating plate mode.As shown in Figure 2, this aluminium floating plate is an aluminum flat board.Be provided with some ball floats between aluminium floating plate and fluid, this ball float floatability is on fluid.By this ball float with aluminium floating plate jack-up, thereby realize sealing function to fluid.
But people also need install the liquid level instrument simultaneously with real-time monitoring fluid height in petrol storage tank.This just need be in the floating plate upper shed to install the liquid level instrument.As shown in Figure 2, common way is to offer a hole on floating plate at present, pierces by this and establishes a standpipe.Welded seal between this standpipe and the floating plate.Like this liquid level instrument is placed in this standpipe, so that the fluid height is measured.Though such way still can guarantee the sealing function of floating plate to most of fluid surface, solved the problem that is provided with of liquid level instrument simultaneously.But in the pipe bucket zone of this standpipe, fluid still can be directly exposed in the air, thereby causes a series of problems that above-mentioned oily vapour volatilization is brought.
Given this, we are necessary to design the better aluminous floating disc opening sealing device of a cover sealing property.
Summary of the invention
The purpose of this utility model is to solve problems of the prior art, provides a kind of and in petrol storage tank the liquid level instrument being installed opening on the aluminium floating plate is implemented the leak free sealing arrangement.
The purpose of this utility model is achieved by following technical proposals:
Be used to install the aluminous floating disc opening sealing device of liquid level instrument, it is characterized in that: comprising: sealed tube, poted assemblies and sealant lid;
Described sealed tube is located at the downside of aluminium floating plate, and its upper port is corresponding with opening on the aluminium floating plate; Upper port place at sealed tube is provided with flange;
The lower port of described poted assemblies is corresponding with opening on the aluminium floating plate; Lower port place at poted assemblies is provided with flange; The top of sealing assembly is taper pipe, and the large mouth of this taper pipe is the upper end open of poted assemblies;
Described sealant lid is truncated cone-shaped; The taper pipe shape of the shape of sealing Jiao Gai and poted assemblies upper end is complementary; Center at the sealant lid offers a perforation.
The lower port of described poted assemblies prolongs, and makes the lower port of sealing assembly pass opening on the aluminium floating plate.
Between the flange of described sealed tube aluminium floating plate, and be provided with the oil resistant packing seal between the flange of aluminium floating plate and poted assemblies.
It is conical that the bottom of described sealed tube is, and wherein large mouth is the lower port of sealed tube.
What described sealant lid adopted is that tincture hydrogen elastomeric material is made.
The beneficial effects of the utility model are: the sealing device makes the liquid level instrument be installed in to carry out level gauging on the steel floating plate on the one hand, the sealing device is by being provided with poted assemblies and sealant lid on the other hand, the area of contact of fluid and air is narrowed down to the piercing aperture size, this has reduced the area of contact of fluid and air greatly, has controlled the evaporation rate of oily vapour.
Description of drawings
Fig. 1 is the mounting structure scheme drawing that is used to install the aluminous floating disc opening sealing device of liquid level instrument;
Fig. 2 is existing aluminous floating disc opening sealed structural representation.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is the mounting structure scheme drawing that is used to install the aluminous floating disc opening sealing device of liquid level instrument.As shown in the figure, the sealing device comprises: sealed tube 1, poted assemblies 2 and sealant lid 3.
This sealed tube 1 is located at the downside of aluminium floating plate, and its upper port is corresponding with opening on the aluminium floating plate.Upper port place at sealed tube 1 is provided with flange, fixes by opening on bolt and the aluminium floating plate.
