Specific embodiment
Embodiment one
Referring to attached drawing 1,2, extraordinary terminal core pipe valve described in the present embodiment is mainly used for vehicle-mounted tank body safety；It is described to contain
The valve core tube 1 being placed in shield 9 isShape be fixing piece its lateral coaxial sleeve I 2 through valve body 2 of pipeline section ', valve body 2
Inner cavity 200, the II 2 " throat of sleeve for touching valve body 2；There are two the radial recirculation hole 103 of well-balanced arrangement and ends for valve core tube 1
Axial two end faces of spool 101 ', end spool 101 ' are spherical surfaces；End spool 101 ' and " annular plate valve of throat of sleeve II 2
" annular inner wall composition secondary sealing that seat 201 constitutes sealing pair, around the sealing ring 302 ' and sleeve II 2 of 101 ' anchor ring of end spool
It is secondary；Valve core tube 1 and sleeve I 2 ' for shaft hole mode cooperate its engaging portion that bellows seal 300 is arranged；I 2 ' internal diameter of sleeve is greater than sleeve
" internal diameter, therefore, inner cavity 200 form pressure difference between axial two end faces to pipe II 2；With the shield of the lateral pipeline section coaxial line of valve core tube 1
There is a through-hole 900 in one end of cover 9, and " compressed spring is arranged in the inner face and sleeve II 2 of 900 circular periphery of through-hole between end face
4。
It shown in attached drawing 1, is in off state, at that time, pressure medium is normal in tank, compressed spring 4 applies pressure to sleeve II 2 " end
Face, valve body 2 moves axially to closed state, sleeve II 2, and " ring-shaped valve seats 201 of throat is closely affixed with end spool 101 ', close
" annular inner wall is closely affixed with sleeve II 2 for seal 302 '.
It is open state shown in attached drawing 2, at that time, pressure medium superelevation in tank, inner cavity 200 is axially between two end faces
Pressure difference forms thrust and valve body 2 is pushed to move axially, and " ring-shaped valve seats 201 of throat leaves end spool 101 ' to sleeve II 2, together
When, sleeve II 2 " ring inner wall leaves sealing ring 302 ', and superpressure medium is through recirculation hole 103, inner cavity 200, sleeve II 2 ", compressed spring
4 and through-hole 900 discharge.
The meaning that firm shield 9 is arranged is that protecting terminal core pipe valve not to be squeezed deformation causes to leak, meanwhile, really
It being capable of normal pressure release when protecting pressure inside the tank superelevation.
The purpose that secondary sealing pair is arranged is to prevent the axial runout either pressure inside the tank of the compressed spring 4 in carry process
