Water oil sleeve type soft sealing flange end connection lift type plug valve

Water oil sleeve type soft sealing flange end connection lift type plug valve

Lift type plug valve according to the sealing surface material can be divided into soft seal and hard seal two kinds. The basic principle is to make the cock rise when it is opened, and the valve can reduce the friction with the sealing surface of the valve body when the cock rotates 90 degrees to the full open process. When closing the valve, turn the cock 90 degrees to the closed position and then drop to contact the sealing surface of the valve body to seal.

Lift type plug valve according to the sealing surface material can be divided into soft seal and hard seal two kinds. The basic principle is to make the cock rise when it is opened, and the valve can reduce the friction with the sealing surface of the valve body when the cock rotates 90 degrees to the full open process. When closing the valve, turn the cock 90 degrees to the closed position and then drop to contact the sealing surface of the valve body to seal.
Connection lift type plug valve has the following advantages: lift plug valve for frequent operation, open and close quickly, light; Low fluid resistance; Lift type plug valve simple structure, relatively small size, light weight, easy maintenance; Good sealing performance; Lift plug valve is not limited by the direction of installation, the flow of media can be arbitrary; No vibration, low noise.
