In figure: the 1-extension tube; 2-valve body compensator; The 3-inner valve body; The 4-vacuum jacket; 5-vacuumizes mouth; The 6-pneumatic diaphragn actuating mechanism; 7-side dress turbo type handwheel; The 8-venting plug; The 9-valve hole part; 10-glass fibre layer of cloth; The 11-mounting bracket; The 12-adsorbent of molecular sieve.
Embodiment
Further illustrate the utility model below in conjunction with Figure of description.
As shown in the figure, a kind of vacuum thermal insulation low temperature modulating valve comprises vacuum jacket 4, and vacuum jacket 4 is vertical chuck, and vacuum jacket 4 bottoms are provided with mounting bracket 11, be convenient to the valve transportation fixing and on-the-spot install fixing.Be provided with inner valve body 3 in vacuum jacket 4, inner valve body 3 outer surfaces coat at least layer of glass layer of cloth 10 are set, glass fibre layer of cloth 10 can effectively strengthen heat insulation effect, be provided with adsorbent of molecular sieve 12 between glass fibre layer of cloth 10 and inner valve body 3, adsorbent of molecular sieve 12 can effectively adsorb the rarefied gas in vacuum jacket 4, the degree of vacuum that maintains a more long.
Inner valve body 3 both sides connect extension tube 1, are provided with valve body compensator 2 between extension tube 1 and inner valve body 3, avoid valve body to shrink under low-temperature condition and pull pipe welding seam, and valve body compensator 2 is with stopper simultaneously, pull valve body compensator 2 when avoiding valves test own.Be equipped with valve hole part 9(in inner valve body 3 and comprise spool and valve seat), be equipped with pneumatic diaphragn actuating mechanism 6 on valve hole part 9, and be provided with side dress turbo type handwheel 7 between pneumatic diaphragn actuating mechanism 6 and valve hole part 9, side dress turbo type handwheel 7 makes modulating valve die, realize during break signal manually-operable, the advantages such as it is little that side dress turbo type handwheel 7 has a volume, laborsaving.
For the ease of will be in inner valve body 3 in time discharge the unnecessary gas of the inside, be provided with venting plug 8 on inner valve body 3 tops.For the ease of vacuumizing the vacuum of chuck 4 inner chambers, be provided with on vacuum jacket 4 and vacuumize mouth 5.
During work, cryogenic media enters inner valve body 3 through extension tube 1, valve body compensator 2, flows out from outlet extending pipe 1 through valve hole part 9 throttlings.Thereby the spool that promotes in valve hole part 9 by the difference of inputting pneumatic diaphragn actuating mechanism 6 bleed pressure signals moves up and down change valve seat orifice size, and output flow is changed, and regulates medium filling speed.
Shown in the above and figure is only preferred implementation of the present utility model.Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model principle, can also make some modification and improvement, these also should be considered as belonging to protection domain of the present utility model.
