Fig. 2 is the structural representation of face sealing among the present invention.
Embodiment
The below lifts a preferred embodiment, and comes by reference to the accompanying drawings the clearer the present invention that intactly illustrates.
As shown in Figure 1, the super abrasion-resisting sliding plate valve of the present invention comprises valve body 1, the first bolt 2, the one O type circle 3, valve gap 4, limiting stopper 5, the 2nd O type circle 6, spring 7, right valve disc 8, left valve disc 9, the 3rd O type circle 10, the 4th O type circle 11, slide plate 12, the second bolt 13, valve shaft 14, axle sleeve 15, the 5th O type circle 16, the 6th O type circle 17, the 3rd bolt 18, land 19, valve gap 4 is fixing with valve body 1 by the first bolt 2, limiting stopper 5 is positioned at the valve pocket of valve body 1 and valve gap 4 formation, spring 7 is between right valve disc 8 and valve body 1, right valve disc 8, left valve disc 9 lays respectively at the both sides of limiting stopper 5, slide plate 12 is positioned at the top of limiting stopper 5, the second bolt 13 is fixed on the valve body 1, valve shaft 14 is positioned at the top of slide plate 12, axle sleeve 15 is enclosed within on the valve shaft 14, and land 19 is fixing with valve body 1 by the 3rd bolt 18.The one O type circle 3 is between valve body 1 and valve gap 4, the 2nd O type circle 6, the 3rd O type circle 10 are between valve gap 4 and right valve disc 8, the 4th O type circle 11 is between valve gap 4 and left valve disc 9, the 5th O type circle 16 is between the 3rd bolt 18 and axle sleeve 15, and the 6th O type circle 17 is between valve shaft 14 and axle sleeve 15.
The stuffing box packing at the movable position of the super abrasion-resisting sliding plate valve of the present invention has V-type teflon and graphite, adds the spring of stainless steel in the stuffing box bottom, keeps a stable filler impacting force with the elastic force of spring.
The present invention is super, and abrasion-resisting sliding plate valve has following characteristics: one, face sealing: relatively linear sealing (such as ball valve etc.), as shown in Figure 2, sealing between slide plate and the valve disc is the face sealing, even the part sealing surface is damaged, the face of periphery can continue to seal, so the long service life of the super abrasion-resisting sliding plate valve of the present invention.Two, automatically cleaning: the motion between slide plate and the valve disc is shearing motion, so the solid dielectric that is bonded on slide plate or the valve disc is easy to be cleaned.Three, friction is little: shearing motion is so that exist without the solid of diameter greater than sealing surface roughness and flatness between slide plate and the valve disc face, and diameter is all very little less than dust and the self-friction between the sealing surface of sealing surface roughness and flatness, it is little to wear and tear, long service life.Four, zero leakage: (slide plate and valve disc surface roughness and flatness are all less than 3um) that zero leakage mainly guarantees by machining accuracy, the up and down valve disc of super abrasion-resisting sliding plate valve has spring system behind, super abrasion-resisting sliding plate valve can remedy the loss of friction, so can be accomplished lifelong zero leakage.And; because diameter can enter between the sealing surface less than the dust of sealing surface roughness and flatness, these media can not scratch sealing surface, can not increase friction yet; on the contrary so that sealing effect become better and better because these dust have been filled up the space between the rough surface.Five, without stopping up: in the process of valve from the standard-sized sheet to the complete shut-down, medium only might with the slide plate circular hole of duct size in temporarily pile up, when valve by complete shut-down in the process of standard-sized sheet, all accumulation mediums all enter pipeline, have not a particle of residual (valve pocket of ball valve easily stops up).Six, complete hiding: when valve wide open, the sealing surface Hide All of slide plate and valve disc can not be subject to the impact of medium, so prolong greatly working life.And the time of full-gear accounts for more than 95% of total possible wearing-in period.Because any valve only has three states: during complete shut-down: the sealing surface of any valve can not impacted, without wearing and tearing.When half-open: any valve all can be impacted, but the time is very short, and general pneumatic valve switch once only has 3-5 second.During standard-sized sheet: the part valve can be subject to impacting (such as moushroom valve), and this state accounts for the overwhelming majority of the time that may wear and tear.Seven, without leaking outside: the face sealing of super abrasion-resisting sliding plate valve is with the interior leakage of valve and the together solution that leaks outside, and medium can only suspend between slide plate and valve disc, can not let out in the valve pocket.
Although more than described the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, under the prerequisite that does not deviate from principle of the present invention and essence, can make various changes or modifications to these mode of executions.Therefore, protection scope of the present invention is limited by appended claims.
