Slurry Manual Knife Gate Valve
1. Introduction
Knife gate valve is a kind of valve gate and seat always close
contact sealing valve, its principle is the gate is open on the
size of a pass size of the round mouth, through the gate opening
and closing of the gate makes the gate on the round mouth with the
pass diameter to do completely detached and coincide with the
action. The advantage of this valve is that the valve body diameter
without grooves, the media will not be blocked blockage, and has a
full diameter circulation characteristics, the sealing structure
can be divided into soft seal, hard seal structure. Penetrating
knife gate valve is characterized by precision construction, good
workmanship, compact structure, etc. The sealing seat is designed
as a movable structure, with anti-wear and automatic compensation
function, thus the life is longer.
In the closing and opening process, the valve seat and the gate
have been close to the movement, so that the valve opening and
closing force is stable, and has the characteristics of cutting off
the medium and so on.
2. Characteristic

compensation function of long service life and other
characteristics.
3, manual plug valve in the normal use of the process of the
transmission parts should be regularly inspected, plus lubricants
to do a good job of maintenance.
