The utility model has the advantages that the present invention proposes that a kind of novel pneumatic high temperature resistant rotary-cutting type V-shaped valve, spool take eccentric v-shaped structure
(shape of the symmetrical section of hemisphere, the axis of spool is not in hemispherical diameter), makes the spatial movement rail of hemisphere V-type valve core sealed cover
Mark reaches idealization, the sealing surface of spool and valve seat between each other without friction, without interference, in addition sealing material selection it is proper, from
And makes leakproofness, corrosion resistance, heat-resisting quantity and the wearability of ball valve etc. and obtained reliable guarantee；Solve it is inconvenient for operation,
The high problem of maintenance cost, more freely, mechanical pneumatic switchs switch valve, and has cooling device.Ball valve uses solid forging
V-shaped structure, guarantee the maximum intensity ratio of sphere.The position that rotates upwardly and downwardly of valve core valve stem is all made of installation and rotates upwardly and downwardly duplex bearing
Structure guarantees the better Push And Release of eccentric V-arrangement sphere.(adjustable) butterfly spring structure is used on seal receptacle, that is, valve seat at sealing,
Butterfly spring is cyclic structure, and butterfly spring is through sealing ring on valve seat, and position is adjustable, guarantees wearing in use
To automatic compensation, guarantee the service life of equipment.Dual airtight and watertight padding case designs on valve rod, and sealing can under the conditions of worst hot case
It leans on.The lower end of valve rod uses the cooling box structure with multiple groups cooling fin, and cooling box outer wall is equipped with multiple groups and protrudes cooling fin, guarantees
Heat dissipation of cooler bin under the conditions of worst hot case.Sphere and seal receptacle use laser melting coating different hardness alloy technology, wear-resistant
It is strong with corrosion resistance；It is applied widely.
