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.
