Description
Technical field
The utility model relates to a kind of pumping skid-mounted device, particularly relates to a kind of pumping skid-mounted device for LNG gas station.
Background technique
The flow process of LNG Vehicle Fueling Station is: the LNG cryogenic liquide in LNG storage tank enters through cryogenic piping, Subzero valve the pump pond that immersed pump is housed, LNG cryogenic liquide is filled in LNG vehicle-mounted bottle through cryogenic piping, Subzero valve by LNG liquid addition machine again after immersed pump adherence pressure, immersed pump in working order time, need in pump to be full of LNG liquid completely, gaseous state LNG must not be had to exist, if gaseous state LNG not yet emptying time start working, then very easily occur the pump housing blocking situation.
For avoiding LNG heated liquid gasification under extremely low temperature; Cryo Equipment, pipeline need carry out insulated heat; at present to vacuumize insulated heat; pipeline, valve, cryogenic pump sump all adopt and vacuumize; although it is good to vacuumize insulated heat heat-insulating property, vacuum pipe, valve and pump pond need be made to measure in advance, and after 3 ~ 5 years, heat-insulating property runs down; maintenance difficulty is large, and device overall cost is higher.
Model utility content
The deficiency that the utility model exists for above-mentioned prior art, provide a kind of pumping skid-mounted device for LNG gas station adopting multilayer insulant to carry out cold insulation, not only insulation effect is good for it, and cost is low, is convenient to safeguard.
The technological scheme that the utility model solves the problems of the technologies described above is as follows: a kind of pumping skid-mounted device for LNG gas station, comprise LNG pump pond and the liquid entering hole with LNG pump pond, what liquid outlet was communicated with respectively enters, go out pipeline, described enter, go out correspondence on pipeline be provided with into, go out valve, it is characterized in that, described LNG pump pond, enter, go out pipeline and enter, go out valve entirety for case structure, the outermost surface of described case structure is stainless protection layer, the inside of described stainless protection layer is heat insulation layer, in described LNG pump pond, enter, the surface going out pipeline and turnover valve is provided with elasticity Cold-keeping Layer, also thermal-protective coating is provided with between described elasticity Cold-keeping Layer and heat insulation layer.The outermost surface of case structure is stainless protection layer, and corrosion resistant plate can be adopted to be mainly used in carrying out protection against the tide and protection to heat insulation layer.
Further, described heat insulation layer adopts the thermoinsulation material of high sealed porosity rate.
Further, described thermal-protective coating adopts the material intercepting convection current and radiative heat transfer.
Further, described elasticity Cold-keeping Layer adopts the elasticity cold insulation material that thermal conductivity is little.
The beneficial effects of the utility model are: the four layers of operator guards arranged by case structure and case structure inside carry out insulated heat to LNG pump pond, pipeline and valve; not only ensure that LNG pump pond and surrounding conduit and valve thereof have the insulation effect identical or better with vacuum insulation; the pipeline making LNG pump pond and be connected with pump pond and valve are in low-temperature condition; avoid the LNG cryogenic liquide in pump pond due to insulation effect not good appearance gasification phenomenon; and do not need to make to measure; cost is low; easy to maintenance, extend its long service life.
