The national standard DN600 Square Cap Gate Valve is refers to
closes the piece (the gate plate) along the Path Center line the
Vertical Direction Movement Valve. National Standard DN600 Square
Cap Gate Valve in the pipeline can only be fully open and fully
closed off, can not be used for regulation and throttling. DN600
Square Cap Gate Valve is a kind of valve which is widely used. It
is usually used for cutting device with diameter DN ≥50mm, and
sometimes for cutting device with small diameter DN600 square cap
gate valve. The opening and closing part of DN600 Square Cap Gate
Valve is the gate plate, the Movement Direction of the gate plate
is perpendicular to the flow direction, the DN600 square cap gate
valve can only be fully opened and fully closed, can not be
adjusted and throttled. DN600 Square Cap Gate Valve is a kind of
valve which is widely used. It is usually used for cutting devices
with diameter DN ≥50mm, and sometimes for cutting devices with
small diameter DN600 square cap gate valve has two sealing
surfaces, the wedge-shaped and wedge-shaped angles of the two
sealing surfaces of the commonly used pattern gate valves vary with
the valve parameters, usually 50, and 2 ° 52'when the medium
temperature is not high. The gate plate of DN600 square cap gate
valve can be made as a whole, which is called rigid gate. It can
also be made into gate plate which can produce slight deformation
to improve its workability and make up for the deviation of sealing
surface angle in the process, this type of gate is called an
elastic gate. National Standard DN600 Square Cap Gate Valve is the
main control equipment for the flow or transportation of powder
material, crystal material, granular material and small piece of
material, widely used in metallurgy, mining, building materials,
grain, chemical and other industries to control flow changes or
rapid cut-off. GB DN600 Square Cap Gate Valve refers to the type of
cast steel GB DN600 Square Cap Gate Valve. According to the sealing
surface configuration can be divided into wedge-type GB DN600
square cap gate valve and parallel GB DN600 square cap gate valve,
dN600 square cap wedge-type National Standard Gate Valve can be
divided into: Single Gate, Double Gate and Elastic Gate; parallel
gate DN600 Square Cap Gate Valve can be divided into single gate
and double gate. According to the screw position of valve stem, can
be divided into stem DN600 square cap gate valve and dark stem
DN600 square cap gate valve. When DN600 Square Cap Gate Valve is
closed, the sealing surface can be sealed only by medium pressure,
that is, the sealing surface of the gate plate is pressed to the
valve seat on the other side by medium pressure to ensure the
sealing surface, which is self-sealing. Most national standard
DN600 Square Cap Gate Valve is the use of forced sealing, that is,
when the valve closed, to rely on external force to press the gate
to the valve seat, to ensure the sealing surface of the seal. GB
DN600 square cap gate valve with the stem of the gate plate for
linear motion, called lifting Rod DN600 Square Cap Gate Valve (is
also known as stem DN600 square cap gate valve) . Usually on the
lifting Rod, there are trapezoidal threads, through the top of the
valve nut and the valve body on the guide Groove, the Rotary
Movement into linear movement, that is, the operation of Torque
into operation thrust. When the valve is opened, the flow path is
fully open when the gate lift is 1:1 of the valve size, but this
position can not be monitored during operation. In actual use, the
apex of the stem is used as a symbol, that is, the position of the
open fixed, as its full open position. In order to take into
account the temperature lock phenomenon, usually in the open to the
top position, and then back 1/2-1 turns, as a full-open Valve
position. Therefore, the full open position of the valve, press the
gate position (I. E. Stroke) to determine. Some national standard
DN600 square cap gate valve, stem nut set on the gate, hand wheel
rotation drive stem rotation, and make gate plate lift, this valve
is called rotating rod DN600 Square Cap Gate Valve or dark rod
DN600 Square Cap Gate Valve./* March 10, 2023 17:59:20
