Close main valve guide wall 3 to move, the secondary matching pair guide wall 4 of valve 403 is moved.
Multilayer complex casing Assemblies Example
Fig. 2 is the profile of multilayer complex casing component provided in an embodiment of the present invention.Fig. 5 is that the embodiment of the present invention provides
Multilayer complex casing component structural representation.As shown in Figure 2 and Figure 5, it is complicated to include multilayer for the multilayer complex casing component
Housing, main valve 400, main valve seat 401, main spring 402, secondary valve 403, auxiliary spring 404 and pin 405.Wherein, multilayer is complicated
The specific implementation process of housing will not be repeated here referring to described above, the present embodiment.
Main valve 400 includes sealing 410, main guide part 420 and secondary guide part 430;Wherein, sealing 410, dominate to
Portion 420 and secondary guide part 430 are integrally formed;Secondary valve 403 is embedded at the inside of secondary guide part 430, and auxiliary spring 404 is sheathed on pair
One end of valve 403;Secondary guide part 430 offers spacing hole 440, and pin 405 is arranged in secondary valve 403 and is stuck in spacing hole
440;One end of secondary guide part 430 is embedded at secondary guide wall 4;Main guide part 420 is embedded at main valve guide wall 3;Main spring 402
Be sheathed on main valve guide wall 3, one end and the spring support seat 10 of main spring 402 fit, the other end of main spring 402 with it is close
The side wall in envelope portion 410 fits;Main valve seat 401 is threadedly coupled with housing exterior walls 1, and main valve seat 401 fits with sealing 410.
Operation principle:The entrance of cryogenic media from housing exterior walls 1 flows into, then between housing exterior walls 1 and deflection cone 2
Passage flows into.Original state is:Main valve 400 is in the presence of the pretightning force of main spring 402, its sealing 410 and main valve seat 401
Fit, before cryogenic media is ended in main valve 400;Main valve 400 is set to overcome the power of main spring 402 in the presence of axial force
Main valve guide wall 3, secondary guide wall 4 it is spacing lower along axis to the lateral movement of arrival end one, open main valve.Secondary valve
403 prior to main valve 400 in place, and entrance through hole is closed, between the main end face of guide part 420 and the internal layer of main valve guide wall 3
A nearly sealing area is formed, the inside is full of cryogenic liquid medium, and main valve 400 continues that when moving to opening direction this portion can be compressed
Liquid separation body, principle can not be pressed by liquid, the liquid medium of sealing area can only slowly flow out from annular space for being oriented to position etc.,
Reach that a kind of fluid damping is slow to open effect so as to not increase independent spare part, protect each structural member not to be hit and cause damage;
Axial force is removed, main valve 400 can return to initial position under the compression force of main spring 402.
