Fig. 2 is the cryogenic insulated cylinder safety valve solar term seat sectional drawing with safety valve.
Embodiment
Below in conjunction with accompanying drawing, by mode of execution, describe cryogenic insulated cylinder safety valve solar term seat provided by the invention in detail.Should be understood that these enforcements are only not used in and limit the scope of the invention for the present invention is described.
A kind of cryogenic insulated cylinder safety valve solar term seat of the present invention, comprise air input joint 1, main body 4, air outlet adapter 11, air input joint 1 front end outer wall is provided with the screw thread being connected with cryogenic insulated cylinder, air input joint 1 rear end be connected with main body 4 front ends and air input joint 1 in be provided with the air inlet cavity 2 of ladder-type, main body 4 rear ends be connected with air outlet adapter 11 front ends and main body 4 in establish mobile cavity 5, in air outlet adapter 11, be provided with the cavity 12 of giving vent to anger, and air outlet adapter 11 front inner wall are provided with the screw thread being connected with safety valve 15.On-link mode (OLM) between described air input joint 1, main body 4 and air outlet adapter 11 can be also welding for screw thread link.Returnning spring 3, valve core nut 6, flap 7 are positioned at mobile cavity 5, wherein Returnning spring 3 one end are pressed on the inwall of air inlet cavity 2, the other end is pressed on the tail end of valve core nut 6, valve core nut 6 front ends are connected with flap 7 tail ends, and flap 7 front ends are pressed on the valve seat 8 that is arranged at air outlet adapter 11 front ends.Described spool 9 front end side wall are provided with more than one spool venting channels 10, spool 9 rear ends are bar-shaped and are provided with screw thread, flap 7 be provided with through hole and through hole internal diameter identical with the spool 9 bar-shaped external diameters in rear end, valve core nut 6 is provided with cavity, this cavity inner wall is provided with the internal thread matching with the spool 9 bar-shaped outer wall threads in rear end, bar-shaped cavity and valve core nut 6 stressed joint that screws in valve core nut 6 through the circular hole on flap 7 in spool 9 rear ends, spool 9 front ends insert gives vent to anger in cavity 12.
During the present invention uses, cryogenic insulated cylinder safety valve solar term seat air input joint 1 is arranged on cryogenic insulated cylinder, air outlet adapter 11 is arranged on safety valve 15, when safety valve 15 screw-in solar term seats are given vent to anger cavity 12 internal thread, safety valve 15 heads on spool 9 and drives valve core nuts 6 and flap 7 to air input joint 1 direction, to move mobile cavity 5 is interior, make flap 7 separated with the valve seat 8 on air outlet adapter 11, air inlet cavity 2, mobile cavity 5 form communication passage by spool venting channels 10 and the cavity 12 of giving vent to anger.During normal use, the pressure of cryogenic insulated cylinder internal gas acts directly on safety valve 15 by communication passage; When safety valve 15 periodic checks need to be changed, without by the gas emptying in cryogenic insulated cylinder, directly pull down safety valve 15, together with now valve core nut 7 drives flap 7 to reset to fit tightly with valve seat 8 under the effect of Returnning spring 3 gentle pressure of the inside of a bottle, play seal action, block the gas in cryogenic insulated cylinder.Load onto after the qualified safety valve of new verification 15, safety valve 15 heads on spool 9 and drives valve core nuts 6 and flap 7 to air input joint 1 direction, to move mobile cavity 5 is interior, make flap 7 separated with the valve seat 8 on air outlet adapter 11, communication passage is opened, and the pressure of cryogenic insulated cylinder internal gas acts directly on safety valve 15 by communication passage.
