Abstract
The utility model discloses a low-temperature pipeline visual filter device. The low-temperature pipeline visual filter device comprises an outer housing, bolts, an outer view port flange, a first sealing pad, a second sealing pad, outer view port glass, an inner view port flange, inner view port glass, an outer view port housing, a molecular sieve, a high vacuum diaphragm valve, an inner view port housing, a filter element and an illuminating lamp, wherein the outer housing, the outer view port housing, the inner view port housing, the filter element and the high vacuum diaphragm valve are connected with one another by a welding mode; the outer view port glass is connected with the outer view port flange by a bolt, the inner view port glass is connected with the inner view port flange by the other bolt, and the first sealing pad and the second sealing pad are arranged between connecting surfaces; the molecular sieve is arranged on the inner side wall surface of the outer view port housing; the illuminating lamp is arranged on the outer view port flange. Due to the heat insulating effect of a vacuum cavity of the visual filter device, low-temperature liquid transfers heat with the outside by the outer view port housing. The heat transfer area is small, the temperature of the outer view port glass is close to room temperature, and thus the outer view port glass is free of frosting and dewing.
Description
Technical field
The utility model relates to the visual filter of a kind of cryogenic pipe, and particularly a kind of carrier rocket cryogenic liquid transfer pipeline is observed liquid flow and contaminant filter situation visual filter used.
Background technology
The visual filter of cryogenic pipe is carrier rocket pressurizing transmission system liquid oxygen Autogeneous pressurization original reason test device therefor, and its effect is in process of the test, to observe the pressurization gas of the impurity such as containing water vapor, carbon dioxide to be mixed into the fluid mobility status that liquid oxygen forms.
One section of glass transparent pipeline section of the many employings of existing visualization device, easily causes the frosting of glass transparent pipeline section outer surface under low temperature, cannot clearly observe the impurity situation of filtering on fluid mobility status and filter core.
Therefore, industry needs the visual filter of a kind of cryogenic pipe.
Utility model content
In order to solve above-mentioned the deficiencies in the prior art, the utility model provides a kind of visual filter with vacuum chamber structure.The utility model has taked to utilize the technical scheme in the parital vacuum chamber that layer glass and housing form, and to solve outer surface frosting problem under existing visualization device low temperature, thereby reaches visual object.
Above-mentioned purpose of the present utility model is achieved by following technical solution: the visual filter of a kind of cryogenic pipe, comprises shell body, bolt, outer viewport flange, the first sealing gasket, the second sealing gasket, outer viewport glass, interior viewport flange, interior viewport glass, outer viewport housing, molecular sieve, high-vacuum diaphragm valve, interior viewport housing, filter core, illuminating lamp; Described shell body, outer viewport housing, interior viewport housing, filter core, high-vacuum diaphragm valve connect by welding manner, outer viewport glass is connected with outer viewport flange by bolt, interior viewport glass is connected with interior viewport flange by bolt, the first sealing gasket, the second sealing gasket are installed between joint face, molecular sieve is installed on outer viewport housing interior sidewall surface, and illuminating lamp is installed on outer viewport flange.
Further, between described outer viewport glass and interior viewport glass, form enclosed cavity, by high-vacuum diaphragm valve, enclosed cavity is vacuumized, form vacuum chamber.
The utility model beneficial effect is compared with prior art:
In the cryogenic liquid process of circulation, the impurity in liquid rests on filter core one side through filter element filtering.Outer viewport glass by visual filter one side can be observed the impurity situation of filtering on liquid flow and filter core.Due to the heat insulating function of vacuum chamber, cryogenic liquid only conducts heat with extraneous by outer viewport housing.Because heat transfer area is little, to outer viewport glass place, approached room temperature, outer viewport glass there will not be frosting dewfall situation.
In the bilateral symmetry with shell body axis angle at 45 °, respectively have an observation window, when observation window and shell body axis are at 45 ° for fear of with formation right angle, housing intersection, with less cryogenic liquid, be detained and generating gasification.Unilateral observation window is installed lighting device, can improve the brightness in visual filter, is convenient to observe from another observation window.
Accompanying drawing explanation
By reading the detailed description that non-limiting example is done of doing with reference to the following drawings, it is more obvious that other features, objects and advantages of the present utility model will become:
Fig. 1 is the visual filter schematic diagram of cryogenic pipe of the present utility model.
In accompanying drawing, same or analogous Reference numeral represents same or analogous parts.
The specific embodiment
Referring to the accompanying drawing that the utility model embodiment is shown, below the utility model will be described in more detail.Yet the utility model can be with many multi-form realizations, and should not be construed as the restriction of the embodiment being subject in this proposition.
Figure 1 shows that the visual filter of a kind of cryogenic pipe, this visual filter comprises shell body 1, bolt 2, outer viewport flange 3, the first sealing gasket 4, the second sealing gasket 8, outer viewport glass 5, interior viewport flange 6, interior viewport glass 7, outer viewport housing 9, molecular sieve 10, high-vacuum diaphragm valve 11, interior viewport housing 12, filter core 13, illuminating lamp 14;
The bilateral symmetry at shell body 1 axis angle at 45 ° respectively has an observation window, unilateral observation window is installed illuminating lamp 14, improve the brightness in visual filter, opposite side observation window is used for the impurity situation that filter at liquid flow in observation tube and filter core place, also camera head can be installed.
Observation window is comprised of outer viewport glass 5, interior viewport glass 6, outer viewport flange 3, interior viewport flange 6, outer viewport housing 9, interior viewport housing 12, the first sealing gasket 4, the second sealing gasket 8, and interior viewport glass contacts with cryogenic liquid.Described shell body 1, outer viewport housing 9, interior viewport housing 12, filter core 13, high-vacuum diaphragm valve 11 connect by welding manner, outer viewport glass 5 is connected with outer viewport flange 3 by bolt 2, interior viewport glass 7 is connected with interior viewport flange 6 by bolt 2, the first sealing gasket 4, the second sealing gasket 8 are installed between joint face, and molecular sieve 10 is installed on outer viewport housing 9 interior sidewall surface.
Between described outer viewport glass 5 and interior viewport glass 7, form enclosed cavity, by 11 pairs of enclosed cavities of high-vacuum diaphragm valve, vacuumized, form vacuum chamber.At vacuum chamber inwall, place the molecular sieve of activated processing, the gas that sorbing material venting produces, maintains the vacuum of vacuum chamber.After assembling vacuum chamber, it is vacuumized to processing, while reaching regulation requirement, close high-vacuum diaphragm valve 11.On outer viewport housing 9, high-vacuum diaphragm valve 11 is installed, long-time placement of visual filter, is caused can continuing to vacuumize after vacuum decline, reach the long-time object of using of device.At vacuum chamber inwall, place the molecular sieve of activated processing, the gas that sorbing material venting produces, can maintain the vacuum of vacuum chamber.
Above embodiment is only for illustrating content of the present utility model, and except above-mentioned embodiment, the utility model also has other embodiment, and all employings are equal to replaces or technical scheme that equivalent deformation mode forms all drops in protection domain of the present utility model.
