Packing type conical plug valve sealing principle

Stuffed conical plug valves with a packing inside the valve body to seal between the valve plug and the valve body sealing surface by compressing the packing. This type of valve is a non-lubricated metal seal. Due to the high friction between such sealing surfaces, the allowable sealing load is limited to ensure that the valve plug can rotate freely within the valve body. Therefore, the sealing surface of the leakage gap is relatively wide, so this valve can only be used in the surface tension and viscosity of the liquid to achieve a satisfactory seal. However, if a plug of grease is applied to the valve plug prior to assembly, the valve can also be used for damp gases, such as wet or oily compressed air. This packing conical plug valve sealing performance is better, especially the leakage of better sealing, a large number of nominal pressure 1.0MPa occasions. Below the body of the screw can play a valve plug and valve body with the regulatory role of elastic.
