It sets, the elastic sealing device includes block, spring and spring base, and the spring is between block and spring base, the valve
The disk other side is equipped with laser cladding layer, sealing ring and two friction blocks, and the sealing ring two sides are inlaid with nickel-base alloy ring, described
Laser cladding layer is WC-Co hard alloy.
As preferred: the ash stop plate matches with sleeve.
As preferred: there are gaps between the card slot and sleeve.
As preferred: the coefficient of friction of described two friction blocks is different.
The utility model has the beneficial effects that
1. the setting of sealing ring guarantees the leakproofness of valve disc and the contact surface of valve seat, nickel-base alloy ring is arranged in sealing ring two sides,
Nickel-base alloy has good wearability, corrosion resistance and heat resistance, and sealing ring is avoided directly to contact with material, extends sealing ring
Service life, reduce valve disc and the contact surface of valve seat abrasion loss.Laser cladding layer, laser cladding layer WC- are set on valve disc
Co hard alloy, WC-Co hard alloy have good thermal conductivity, impact flexibility and wearability, so that it is guaranteed that valve disc is with excellent
Good wearability and high-temperature erosion-resistant performance.
2. there are gaps between card slot and sleeve, different coefficients of friction is set on sleeve rotating, valve disc convenient for valve disc
Friction block, the frictional force for being subject to valve disc on the move is different, so that valve disc rotation be made to carry out self-grind, guarantees good sealing
Property, prolong the service life.Wear plate is set in card slot, avoids valve disc from directly contacting with sleeve and spring base, effectively extends valve
The service life of disk, the setting of ash stop plate can be effectively prevented dust and enter elastic sealing device, guarantee elastic sealing device
It operates normally, the elastic force of spring precompressed fits closely valve disc and valve base surface by spring base, guarantees the leakproofness of valve disc, together
When can also compensate the abrasion loss and thermal deformation amount of valve disc, valve seat, card slot and wear plate, so that valve disc is possessed enough flying abilities
The environment of high temperature, low temperature and high/low temperature alternation is adapted to, is avoided because temperature change leads to spool bite, locking or serious leak
Possibility.
3. chamfering is arranged in valve disc edge, it is equivalent to scraper, the material of valve base surface can be cleaned, material can be prevented to enter close
Cover prevents material from scratching the sealing surface of valve disc and valve seat, extends the service life of spool.

Specific embodiment
A kind of novel wear resistant valve disc of -2 pairs of the utility model is described further referring to Fig.1.
A kind of novel wear resistant valve disc, including valve disc 1, it is characterized in that: the valve disc side is equipped with card slot 5,5 bottom of card slot
Face is equipped with wear plate 10, and the wear plate 10 is equipped with ash stop plate 11, sleeve 6 is equipped in the card slot 5, is set in the sleeve 6
Flexible sealing device, the elastic sealing device include block 7, spring 8 and spring base 9, and the spring 8 is located at 7 He of block
Between spring base 9,1 other side of valve disc is equipped with laser cladding layer 2, sealing ring 3 and two friction blocks 12, the sealing ring 3
Two sides are inlaid with nickel-base alloy ring 4, and the laser cladding layer 2 is WC-Co hard alloy.The ash stop plate 11 and 6 phase of sleeve
Match.There are gaps between the card slot 5 and sleeve 6.The coefficient of friction of described two friction blocks 12 is different.
