Electric Gate Valve Cast Steel Plug-in 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
Electric plug valve in the use of precautions and its
characteristics: plug valve opening and closing member is the gate,
the movement direction of the gate is perpendicular to the
direction of the fluid, the plug valve can only be used for full
open and full closed, can not be used for regulation and
throttling. Gate has two sealing surfaces, the most commonly used
mode of gate valve two sealing surfaces to form a wedge, wedge
angle with the valve parameters vary, usually 50, wedge-type gate
valve gate can be made into a whole, called the rigid gate; can
also be made to produce a small amount of deformation of the gate,
in order to improve its craftsmanship, to make up for the angle of
the sealing surface of the bias in the machining process, this gate
is called the resilient gate gate gate valve closure, the sealing
surface can only rely on the medium pressure, the sealing surface
can only rely on the pressure of the fluid, the sealing surface can
only be closed, not for regulating and throttling. Sealing surface
can only rely on media pressure to seal, that is, relying on media
pressure will be the sealing surface of the gate to the other side
of the valve seat to ensure that the sealing surface of the seal,
this is the self-sealing. Most of the plug valve is used to force
sealing, that is, when the valve is closed, to rely on external
forces to force the gate to the valve seat to ensure that the
sealing surface of the sealing. Plug valve sealing structure can be
divided into soft seal, hard seal structure.
