Description
Technical field
The utility model belongs to detection field, especially a kind of device for measuring LNG gas cylinder liquid level.
Background technology
LNG is a kind of clean, efficient novel energy, is mainly used in city bus, environmental sanitation vehicles, taxi, intercity big bus, heavily blocks on these vehicles.The capacitance level transducer generally used at present is made up of coaxial two stainless-steel tubes substantially, is welded on LNG gas cylinder internal and uses.Problems existing is the problems such as processing technology is many, construction is complicated, measuring accuracy is not high.
Summary of the invention
The utility model in order to processing technology, cost-saving, better guarantee liquid level meter measuring accuracy and ensure good flowing properties, provide a kind of novel insulating medium sensor construction.
To achieve these goals, the technical solution of the utility model is achieved in that the new structure of a kind of insulating medium sensor of the utility model, comprise welding base, upper centring ring, upper insulation sleeve, urceolus, inner core, lower centring ring and lower insulation sleeve, described welding base is fixed together by wringing fit and described urceolus, on described, lower insulation sleeve is pressed on the top and bottom of described inner core inwall respectively, on described, lower centring ring be arranged on described on, be welded on urceolus in the endoporus of lower insulation sleeve, described inner core upper end is provided with inner core air equalizer opening, lower end is provided with liquid level equilibrium hole, described welding base is provided with messenger string holes and pore.
Further, in described inner core, be provided with internal fixtion circle, described internal fixtion circle is provided with aperture.
Further, described upper and lower centring ring is a kind of petal type centring ring.
Further, described urceolus lower end is provided with lead channel.
After adopting said structure, have the following advantages:
1, urceolus lower end does not need welding base, structure simple, solid and reliable, stable performance, minimizing processing technology after making monoblock type, reduces costs;
2, urceolus upper end and welding base utilize to be tightly fixed, and facilitates the fine setting of short transverse;
3, adopt the centring ring of petal type, void ratio is conducive to more greatly liquid and flows into and prevent blocking and Stability Analysis of Structures is reliable;
4, urceolus adopts integral type, and lower end has inlet opening directly can be welded on LNG gas cylinder inwall, reduces manufacturing procedure, structure is simple, easy for installation, measuring accuracy is high.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1: the utility model structural drawing.
Wherein, 1, pore; 2, messenger string holes; 3, welding base; 4, upper centring ring; 5, upper insulation sleeve; 6, urceolus; 7, inner core air equalizer opening; 8, internal fixtion circle; 9, inner core; 10, liquid level equilibrium hole; 11, lower centring ring; 12, lower insulation sleeve; 13, lead channel.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As shown in Figure 1, the new structure of a kind of insulating medium sensor of the utility model, comprises welding base (3), upper centring ring (4), upper insulation sleeve (5), urceolus (6), inner core (9), lower centring ring (11) and lower insulation sleeve (12), described welding base (3) is fixed together, on described by wringing fit and described urceolus (6), lower insulation sleeve (5), (12) top and bottom of described inner core (9) inwall are pressed on respectively, on described, lower centring ring (5), (11) be arranged on described on, lower insulation sleeve (5), (12) be welded on urceolus (6) in endoporus, described inner core (9) upper end is provided with inner core air equalizer opening (7), lower end is provided with liquid level equilibrium hole (10), described welding base (3) is provided with messenger string holes (2) and pore (1), internal fixtion circle (8) is provided with in described inner core (9), described internal fixtion circle (8) is provided with aperture, and described is upper, lower centring ring (5), (11) be a kind of petal type centring ring, described urceolus (6) lower end is provided with lead channel (13).
Described inner core relies on inwall to be fixed with insulation sleeve up and down, is directly welded on outer tube inner wall after insulation sleeve endoporus is fixing with centring ring, inner/outer tube is kept coaxially and firm.The lower end of inner core leaves liquid level equilibrium sky, and air pressure balance sky is left in upper end.Centring ring makes petal type, leaves enough spaces and ensures that liquid flows into inner/outer tube, prevent the blocking of impurity.Insulation sleeve and urceolus directly leave a fixed gap, and make taper type and be easy to feed liquor.
Internal fixtion lap welding is connected on inner core upper end, is connected and has some ventholes with signal wire.Urceolus lower end is uniformly distributed four lead channel, directly can weld with ING gas cylinder, and the operation reducing welding base compared with the past, also saves cost simultaneously.
Upper welding base is closely fixed by a kind of wringing fit relation and urceolus, is convenient to the assembling fine setting of short transverse, reduces welding technology.Welding base has a signal string holes, upper end has outgassing groove.
More than show and describe ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
