Abstract
The utility model discloses a novel standard metal measuring vessel for vacuum heat preservation, and belongs to the technical field of measurement instruments. The novel standard metal measuring vessel for the vacuum heat preservation aims at solving the problems that an existing standard metal measuring vessel for verification is unreasonable in structural design, and a metal measuring vessel main body is poor in heat preservation property. A metal measuring vessel main body container liner is composed of a lower conical body, a middle cylinder body and an upper conical body of the metal measuring vessel main body in a connection mode. An outer protective shell is covered on the metal measuring vessel main body container liner and the exterior of a gauge neck of the upper portion of the connection of the upper conical body. A sealed vacuumized clamping cavity is formed between the outer protective shell and the metal measuring vessel main body container liner and between the outer protective shell and the gauge neck. The metal measuring vessel for the vacuum heat preservation with a double-layer structure is combined. The novel standard metal measuring vessel for the vacuum heat preservation is simple in structure, good in heat preservation property, simple and convenient to operate and use and applicable to verifying various types of oiling machines, liquid measuring vessels and the like.
Description
Technical field
The utility model belongs to a kind of measurement verification standard capacity measure in the standard metering Instrument technology field.
Background technology
Along with development and the technical progress of standard metering instrument, also more and more higher with the technical requirement of the legal measurement instrument of standard capacity measure such as fuel oil refueling machinery etc. to measurement verification.in known technology, existing fuel oil refueling machinery is examined and determine with standard capacity measure mainly by the conjuncted single-layer metal measuring device main body that upper lower cone is arranged in the up and down of middle circle cylindrical shell, the metering neck, overflowing hood, the nozzle carriage, go out muzzle thermometric borehole jack, release shunting bend pipe, liquid level tube, the liquid level marking device, the tapping valve, the compositions such as leveling support, but limit by its structure, its structural design is unreasonable, heat-insulating property is poor, when being used for outdoor in-line calibration, especially in summer be in winter under the larger condition of the temperature difference of medium temperature and environment temperature, directly affect calibration operation, the calibrating effect is relatively poor, and complex operation, bring inconvenience to use.
Summary of the invention
In order to overcome the deficiencies in the prior art, solve existing calibrating and use the standard capacity measure structural design unreasonable, the problem that metal tank main body heat-insulating property is poor.The purpose of the utility model is to provide a kind of simple in structure, heat insulating ability and shock resistance are good, can in summer and winter oil temperature environment temperature differ under larger condition, no matter good at indoor or outdoors online assignment assay performance stablizing effect, operate new-type metal tank easy to use.
The technical scheme in the invention for solving the above technical problem is:
a kind of novel standard metal tank of vacuum heat-preserving, it is provided with: the metal tank main body, the metering neck, overflowing hood, the nozzle carriage, go out muzzle thermometric borehole jack, release shunting bend pipe, liquid level tube, the liquid level marking device, the tapping valve, the leveling support, the lower cone of metal tank main body, the middle circle cylindrical shell, the conjuncted outside ladle cover of metering neck in the metal tank main body container inner bag of the conjuncted composition of upper cone and upper cone top has outer protecting crust, press from both sides the chamber for vacuumizing of sealing between outer protecting crust and metal tank main body container inner bag and metering neck, the double-layer structural vacuum heat insulation type metal tank that consists of.
The novel standard metal tank of above-mentioned vacuum heat-preserving, the surface of described metal tank main body container inner bag, metering neck and outer protecting crust all are made for and stop thermal-radiating polished surface.
The novel standard metal tank of above-mentioned vacuum heat-preserving, the outside surface of described metal tank main body container inner bag, metering neck and the inside surface of outer protecting crust (i.e. the chamber perisporium is pressed from both sides in vacuumizing of sealing) all are made for and stop thermal-radiating silver coating; Or any of aluminium coated, tin coating, chromium coating, copper plate, and other applicable coating.
The novel standard metal tank of above-mentioned vacuum heat-preserving, described liquid level marking device are any among mechanical vernier caliper, electronic cursor slide calliper rule, magnetic railings ruler, magnetic stretching tank gage, liquid level sensor, and the liquid level marking device of other adaptive type.
When this Novel metal measuring vessel uses, the same with existing standard capacity measure, by design and standard-required, be no matter under summer and winter oil benign environment temperature differ larger condition, all can normally carry out the calibration operations such as the online fuel charger of indoor or outdoors, liquid measuring device.
Because technique scheme has been adopted in the utility model design, it is also the technical requirement according to national JJG259-2005 " standard capacity measure ", innovate in conjunction with long-term practice and complete, effectively solved existing calibrating unreasonable with the standard capacity measure structural design, the problem that metal tank main body heat-insulating property is poor.Show through testing result on trial for several times, it compared with prior art, have simple in structure, heat insulating ability and shock resistance are good, can in summer and winter oil temperature environment temperature differ under larger condition, no matter good at indoor or outdoor online assignment assay performance stablizing effect, operate the advantages such as easy to use, be applicable to examine and determine various fuel charger, liquid measuring device etc.
