Body and valve body integrally connected, valve inner body are double-layer structure, and the same end outer surface of inside and outside layer is pyramidal structure, in valve in vivo,
Cavity is equipped between outer layer, volume surrounding is hollow body in valve, and valve inner body vertical direction is a support construction, through valve inner body
Inside and outside layer, and be connected with valve body.
As a further improvement on the present invention, waveform spring is equipped between the sleeve and valve inner body, and passes through valve seat quilt
Trim ring is pressed in valve inner body.
As a further improvement on the present invention, Q shape sealing rings, the Q shape sealing rings are equipped between the sleeve and valve seat
With spool axial direction auxiliary seal.
As a further improvement on the present invention, it is equipped with the first balanced seal ring between the spool and valve inner body, described the
One balanced seal ring is Bidirectional seal structure.
As a further improvement on the present invention, the second balanced seal ring and third are used between the guide rod and guide sleeve
Balanced seal ring seals, and sets the first guidance tape and the second guidance tape in guide sleeve to be oriented to guide rod.
The technical effects of the invention are that:High Pressure Difference axial flow control valve of the present invention is suitable for High Pressure Difference operating mode, monoblock type
Structure, securely and reliably, production and assembly are convenient;Spool, guide rod use balance type structure, can realize medium two-way flow, and
And executing agency's thrust needed for action is smaller;Balanced seal ring and guide ring composite structure, guide effect is good, is less prone to bite
Phenomenon, service life is long, and reliability is high.
