There are many types of sealing surfaces, including plane, convex surface, concave-convex surface, tenon-groove surface and ring connection surface. Materials are carbon steel, stainless steel, alloy steel, copper, aluminum, PVC and PPR.
Function and classification of blind plate
From the appearance, blind plates are generally divided into plate-type flat blind plates, figure-eight blind plates, insert plates and cushion rings (the insert plates and cushion rings are mutually blind). Blind plate plays the role of isolation and cutting off, which is the same as that of head, pipe cap and welding plug. Because of its good sealing performance, it is generally used as a reliable isolation means for systems that need complete isolation. Plate blind plate is a solid circle with handle, which is normally used for isolation system.
The splayed blind plate is splayed, one end is a blind plate, and the other end is a throttling ring, but the diameter is the same as the pipe diameter, so it has no throttling effect. The figure 8 blind plate is easy to use. Use blind plate end when isolation is needed, and use throttle ring end when normal operation is needed. It can also be used to fill the installation gap of the blind plate on the pipeline. Another feature is that the logo is obvious and it is easy to identify the installation state.
