Abstract
The invention relates to a sealing structure of a knife gate valve or a slurry valve, which is suitable for the sealing of a gate plate and a valve body. The sealing structure comprises a gate plate and a sealing strip, wherein the sealing strip is matched with the gate plate. The contact surface between the sealing strip and the gate plate is a concave-convex matching surface. The contact surface between the sealing strip and the gate plate can be a horn-shaped concave surface with sealed top, or a circular arc-shaped concave surface, or an approximate angle-shaped concave surface, and the like. As the contact surface between the sealing strip and the gate plate is the concave-convex matching surface, both sides of the gate plate are coated by the sealing strip. When the front surface or back surface of the gate plate is subjected to strong medium pressure, both two sides of the gate plate are respectively appressed with the back surface or the front surface of the sealing strip, the good sealing effect can be still maintained, and the service life of the sealing strip can be prolonged.
Description
Technical field
The present invention relates to the sealing configuration of a kind of disconnecting link valve or Parallel Slide Valves, be applicable to the sealing of flashboard and valve body.
Background technique
The flashboard of disconnecting link valve or Parallel Slide Valves and the sealing configuration between the valve body, comprise flashboard, valve body and be fixed on the valve body and with the Stamping Steel Ribbon of flashboard fitted seal.As shown in Figure 1, Stamping Steel Ribbon is that plane (facing directly) cooperates with the flashboard surface of contact, and promptly the side that contacts with flashboard of Stamping Steel Ribbon is shaped as the plane.There is following defective in the Stamping Steel Ribbon of this shape when using: when flashboard front or the back side were subjected to stronger medium (fluid) pressure, displacement before and after flashboard is easy to generate influence sealing effect, and flashboard can break away from Stamping Steel Ribbon in the time of seriously, causes valve leak.For preventing the flashboard displacement, must add the lateral pressure of big damper to Stamping Steel Ribbon, make flashboard be close to Stamping Steel Ribbon.Stamping Steel Ribbon is worked under overvoltage condition, damages easily, not only influences sealing effect, and shortens the working life of Stamping Steel Ribbon.
Summary of the invention
For overcoming the defective that sealing configuration exists between existing disconnecting link valve or Parallel Slide Valves flashboard and the valve body, the invention provides a kind of flashboard of good sealing effect and the sealing configuration between the valve body.
The technical solution used in the present invention is: the sealing configuration of a kind of disconnecting link valve or Parallel Slide Valves, comprise flashboard and the Stamping Steel Ribbon that cooperates with flashboard, and the surface of contact of described Stamping Steel Ribbon and flashboard is concavo-convex fitting surface.
Best, the face that Stamping Steel Ribbon contacts with flashboard be shaped as concave panel, the face that flashboard contacts with Stamping Steel Ribbon be shaped as convex panel.Flashboard is the intensity that convex panel can increase flashboard.
The beneficial effect that the present invention has is: because the surface of contact of Stamping Steel Ribbon and flashboard is concavo-convex fitting surface, especially the surface of contact of Stamping Steel Ribbon and flashboard is a concave panel, the flashboard of contact matching is a convex panel with it, the flashboard bi-side are in the parcel of Stamping Steel Ribbon, when flashboard front or the back side are subjected to than strong medium pressure, the flashboard bi-side are adjacent to the back or the previous section of Stamping Steel Ribbon respectively, still keep good sealing effect.And compare with the sealing of existing plane contact, can use less flashboard lateral pressure, reduce the lateral pressure of flashboard, the working life of effectively improving Stamping Steel Ribbon to the Stamping Steel Ribbon sealing surface.
The invention will be further described below in conjunction with the drawings and the specific embodiments.
