Abstract
The invention discloses a kind of mounting structure that can make the LNG storage tank level meter of level meter Measurement accuracy, comprise the gas phase PRESSURE PIPE be connected with storage tank inner bag top and the liquid phase PRESSURE PIPE be connected bottom storage tank inner bag, be arranged on level meter between gas phase PRESSURE PIPE and liquid phase PRESSURE PIPE, described gas phase PRESSURE PIPE comprises the interior pipe of the gas phase be located in storage tank thermal insulation interlayer and passes the gas phase outer tube of storage pipe shell, and in gas phase, pipe is connected with storage tank shell by some Steel Supports.
Description
Technical field
The present invention relates to a kind of LNG storage tank, particularly relate to a kind of mounting structure of LNG storage tank level meter.
Background technique
The mounting structure of LNG storage tank level meter comprises the gas phase PRESSURE PIPE be connected with storage tank inner bag top and the liquid phase PRESSURE PIPE be connected bottom storage tank inner bag, be arranged on level meter between gas phase PRESSURE PIPE and liquid phase PRESSURE PIPE, the equilibrium valve in parallel with level meter is also provided with, for checking whether level meter can normally work between gas phase PRESSURE PIPE and liquid phase PRESSURE PIPE.The end of gas phase PRESSURE PIPE is provided with pressure gauge.When checking level meter, open equilibrium valve, level meter zero then illustrates that level meter can normally use.But owing to containing a certain amount of propane in LNG, its boiling point is at about-42 DEG C, opening equilibrium valve can make some propane enter in the gas phase PRESSURE PIPE of storage tank, after long-time use, propane easily forms fluid column at meteorological pilot in-tube condensation, causes gaseous pressure to be forbidden thus affects the accuracy of level meter.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of mounting structure that can make the LNG storage tank level meter of level meter Measurement accuracy.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: the mounting structure of LNG storage tank level meter, comprise the gas phase PRESSURE PIPE be connected with storage tank inner bag top and the liquid phase PRESSURE PIPE be connected bottom storage tank inner bag, be arranged on level meter between gas phase PRESSURE PIPE and liquid phase PRESSURE PIPE, described gas phase PRESSURE PIPE comprises the interior pipe of the gas phase be located in storage tank thermal insulation interlayer and passes the gas phase outer tube of storage pipe shell, and in gas phase, pipe is connected with storage tank shell by some Steel Supports.
As the preferred scheme of one, in described Steel Support and described gas phase, between pipe, be provided with layers of glass fibre matting.
As the preferred scheme of one, described liquid phase PRESSURE PIPE comprises the interior pipe of the liquid phase be located in storage tank thermal insulation interlayer and passes the liquid phase outer tube of storage pipe shell, and described level meter is arranged between described gas phase outer tube and liquid phase outer tube.
As the preferred scheme of one, described Steel Support is stainless steel stent.
The invention has the beneficial effects as follows: manage because described gas phase PRESSURE PIPE comprises in the gas phase be located in storage tank thermal insulation interlayer and pass the gas phase outer tube of storage pipe shell, in gas phase, pipe is connected with storage tank shell by some Steel Supports, because the heat-conducting property of metal is good, the energy heats PRESSURE PIPE of shell can be utilized, avoid propane at gas phase pilot in-tube condensation and form fluid column, thus guaranteeing the accuracy that level meter is measured.
Owing to being provided with layers of glass fibre matting between pipe in Steel Support and described gas phase, the speed that cold passes to shell can being extenuated, shell is not arrived by low-temperature frozen.
Manage because liquid phase PRESSURE PIPE comprises in the liquid phase be located in storage tank thermal insulation interlayer and pass the liquid phase outer tube of storage pipe shell, shortening the length that liquid phase PRESSURE PIPE is positioned at the outer part of storage tank, the loss of heat can be reduced.

Embodiment
Below in conjunction with accompanying drawing, describe specific embodiment of the invention scheme in detail.
As shown in Figure 1-2, the mounting structure of LNG storage tank level meter, comprises the gas phase PRESSURE PIPE be connected with storage tank inner bag top and the liquid phase PRESSURE PIPE be connected bottom storage tank inner bag, is arranged on level meter between gas phase PRESSURE PIPE and liquid phase PRESSURE PIPE.Described gas phase PRESSURE PIPE comprises the interior pipe of the gas phase be located in storage tank thermal insulation interlayer and passes the gas phase outer tube of storage pipe shell, and in gas phase, pipe is connected with storage tank shell by some stainless steel stents.Layers of glass fibre matting is provided with between pipe in stainless steel stent and described gas phase.Liquid phase PRESSURE PIPE comprises the interior pipe of the liquid phase be located in storage tank thermal insulation interlayer and passes the liquid phase outer tube of storage pipe shell, and described level meter is arranged between described gas phase outer tube and liquid phase outer tube.The equilibrium valve in parallel with level meter is provided with between gas phase outer tube and liquid phase outer tube.The end of gas phase PRESSURE PIPE is provided with pressure gauge.
The mounting structure of this LNG storage tank level meter, even if make propane enter in the gas phase PRESSURE PIPE of storage tank when checking level meter, stainless steel stent can, by pipe in the heat conduction of storage tank shell to gas phase, prevent propane from forming fluid column at meteorological pilot in-tube condensation.
The above embodiments are the principle of illustrative the invention and effect thereof only, and the embodiment that part is used, but not for limiting the present invention; It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection scope of the present invention.
