Open Closed Type Manual Knife Gate Valve Flange Cast Steel Gate Valve Wafer 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
Knife gate valve has the advantages of simple and compact structure, reasonable design, lightweight and material saving, reliable sealing, light and flexible operation, small size, smooth channel flow, small flow resistance, light weight, easy to install, easy to dismantle, etc., can be in the working pressure of 1.0MPa-2.5MPa, the use of the temperature-29-650 ℃ under normal operation. Knife gate valve gate has a shear function, can scrape the adhesion on the sealing surface, automatically remove debris, stainless steel gate can prevent corrosion-induced seal leakage.
