Step, and it is equipped with cricoid stepped hole in spool bottom, which is sleeved on cartridge cover board bottom portion by the stepped hole of bottom
On step, fastener is detachably installed in spool cover board top outer, so that spool and spool cover board are integrally fixed.
Wherein fastener uses round nut, is also equipped with locked spacer outside the round nut.
The second elastic element wherein is installed in stem bottom and spool cover board junction, and in spool bottom and cartridge cover
Plate junction is equipped with the first elastic element.
Wherein the first elastic element is waveform spring or butterfly spring, and the second elastic element is also waveform spring or butterfly bullet
Spring.
Wherein stop pin is straight pin or taper bolt.
Wherein spool uses tungsten carbide, aluminium oxide or zirconium oxide material.
The beneficial effect of the connection structure of spool and valve rod of the present invention is: the connection structure of spool and valve rod of the present invention, knot
Structure reasonably stability can effectively solve the problem that temperature is high, pressure drop is big, cinder content is high, corrosivity is strong, and medium is solid, liquid, gas three
Mutually spool caducous problem from valve rod in the bad working environments of stream.
