Ball valve
Ball valve, a valve in which the opening and closing parts (ball)
are driven by the valve stem and rotate around the axis of the ball
valve. It can also be used for fluid adjustment and control. The
hard-sealed V-shaped ball valve has a strong shear force between
the V-shaped core and the metal seat of the hard alloy overlay,
which is especially suitable for fibers and small solid particles.
And other media.
The multi-way ball valve can not only flexibly control the
confluence, divergence, and flow direction switching of the medium
in the pipeline, but also close any channel and connect the other
two channels.
Gate Valve
The gate valve is a gate for opening and closing. The movement
direction of the gate is perpendicular to the direction of the
fluid. The gate valve can only be fully opened and fully closed,
and cannot be adjusted or throttled.
The gate valve is sealed by the contact between the valve seat and
the gate plate, and the sealing surface is usually welded with
metal materials to increase wear resistance, such as 1Cr13, STL6,
stainless steel, etc.
The gate has a rigid gate and an elastic gate. According to the
difference of the gate, the gate valve is divided into a rigid gate
valve and an elastic gate valve.
Check valve
This kind of valve is used to prevent the medium from flowing back,
using the kinetic energy of the fluid itself to open by itself, and
automatically close when flowing in the reverse direction. Standing
at the outlet of the water pump, the outlet of the steam trap and
other places where the reverse flow of fluid is not allowed. There
are three types of check valves: swing type, lift type and wafer
type. For the swing check valve, when the fluid can only flow from
left to right, it will automatically close when it flows in the
reverse direction. For the lift check valve, when the fluid flows
from left to right, the valve core is lifted to form a passage.
When the flow is reversed, the valve core is pressed to the valve
seat and closed. For the wafer check valve, when the fluid flows
from left to right, the valve core is opened to form a passage.
When the flow is reversed, the valve core is pressed to the seat
and closed. The wafer check valve can be multiple positions
Installation, small size, light weight and compact structure.
