The deficiency existing for prior art, when the purpose of this utility model is to provide a kind of keying, process-liquid medium can not enter the flashboard of valve rod and flashboard joint and good airproof performance.
For achieving the above object, the utility model provides following technological scheme: a kind of flashboard, comprise first component, second component and for being sheathed on the elastic component on valve rod, described first component is provided with the first sphenoid surface and connection groove for being connected with valve rod, described second component comprises vertical joint and level connection joint portion, one end of described vertical joint is connected with the end face of level connection joint portion, described level connection joint portion is provided with for wearing the through hole of valve rod, described vertical joint is provided with the second sphenoid surface, described the first sphenoid surface and the second sphenoid surface are close to setting, the other end of relative the second sphenoid surface of described first component and the vertically other end of the relative first component of joint are vertically level and smooth end face, described elastic component is located between level connection joint portion and the first assembly.
By adopting technique scheme, changed inclined-plane sealing means in the past, this makes flashboard and the contact surface of valve seat can be vertically level and smooth, so arrange, in the process opening and closing at flashboard, between valve seat and flashboard, there is not gap, flowing medium can not enter into valve rod and flashboard joint, and the elastic force providing due to elastic component, two sphenoid surface that first component and second component fit are pushed mutually, make two close-connected whiles of parts, a horizontal extruding force is provided, flashboard and valve seat are fitted tightly, good airproof performance.
The utility model is further set to: described vertical joint increases setting gradually along being cross-section area away from level connection joint portion direction.
By adopting technique scheme, make first component and second component under the elastic force effect of elastic component, two sphenoid surface can push mutually, fit tightly, and horizontal extruding force is provided, and flashboard and valve seat are fitted tightly, good airproof performance.
The utility model is further set to: described vertical joint and level connection joint portion are L-type setting.
By adopting technique scheme, make the rational in infrastructure of second component, make simply, save material, and vertical annexation is for elastic component provides good focusing surface, makes structural stability efficient.
The utility model is further set to: described elastic component is holddown spring.
By adopting technique scheme, the elastic force of holddown spring overcomes second component self gravitation, and a pretightening force is provided, and makes to fit tightly between two sphenoid surface of first component and second component always, and the mutual extruding between sphenoid surface makes flashboard integral body be close to valve seat, improves sealing.
The utility model is further set to: described the first sphenoid surface and the second sphenoid surface are equipped with plasma spraying nickel base alloy layer.
By adopting technique scheme, improve the frictional behaviour between the first sphenoid surface and the second sphenoid surface, play better sealing effect.
