Industrial
Valve Course |
| |
Valve is a device that regulates the flow of
substances (either gases, fluidized solids,
slurries, or liquids) by opening, closing, or
partially obstructing various passageways. Valves
are technically pipe fittings, but usually are
discussed separately. Valves are used in a variety
of applications including industrial, military,
commercial, residential, and transportation. Oil &
Gas, Power Generation, Mining, Water Reticulation,
Sewerage & Chemical Manufacturing would constitute
the majority of valves used by industry. Plumbing
valves are the most obvious in everyday life, taps
for hot and cold water, gas control valves on
cookers and barbecues, small valves fitted to
washing machines and dishwashers, safety devices
fitted to hot water systems are all simple valves.
Most valves are operated manually, either by a hand
wheel or lever. Some valves are 'self operating'
driven by changes in pressure, temperature or flow.
These changes in pressure or temperature often act
against springs or capsules filled with expanding
substances. Examples of this type of valve found
commonly are safety valves fitted to hot water
systems or steam boilers. Valves are also found in
the Otto cycle (internal combustion) engines driven
by a camshaft, lifters and or push rods where they
play a major role in engine cycle control.

Course 1- Butterfly
Valve |
|
|
A butterfly valve is a type of flow control
device, typically used to regulate a fluid
flowing through a section of pipe. The valve is
similar in operation to a ball valve. A flat
circular plate is positioned in the center of
the pipe. The plate has a rod through it
connected to an actuator on the outside of the
valve. Rotating the actuator turns the plate
either parallel or perpendicular to the flow.
Unlike a ball valve, the plate is always present
within the flow, therefore a pressure drop is
always induced in the flow regardless of valve
position.

A Check valve or
Clack valve is a mechanical device, a valve,
that normally allows fluid (liquid or gas) to
flow through it in only one direction. Check
valves are two-port valves, meaning they have
two openings in the body, one for fluid to enter
and the other for fluid to leave. There are
various types of check valves used in a wide
variety of applications. Check valves are often
part of common household items. Although they
are available in a wide range of sizes and
costs, many check valves are very small, simple,
and/or cheap. Check valves work automatically
and most are not controlled by a person or any
external control; accordingly, most do not have
any valve handle or stem. The bodies (external
shells) of most check valves are made of plastic
or metal.

Course 3- Diaphragm Valve |
|
|
Diaphragm valves
(or membrane valves) consists of a valve body
with two or more ports, a diaphragm, and a
"saddle" or seat upon which the diaphragm closes
the valve. The valve is constructed from either
plastic or steel. Originally, the diaphragm
valve was developed for use in non-hygienic
applications. Later on the design was adapted
for use in the bio-pharmaceutical industry by
using compliant materials that can withstand
sanitizing and sterilizing methods. There are
two main categories of diaphragm valves: one
type seals over a "weir" (saddle) and the other
(sometimes called a "straight-way" valve) seals
over a seat.

A
safety valve is a valve mechanism for the automatic
release of a gas from a boiler, pressure vessel, or
other system when the pressure or temperature
exceeds preset limits. It is part of a bigger set
named Pressure Safety Valves (PSV) or Pressure
Relief Valves (PRV). The other parts of the set are
named relief valves, safety relief valves,
pilot-operated safety relief valves, low pressure
safety valves, vacuum pressure safety valves. Safety
valves were first used on steam boilers during the
industrial revolution. Early boilers without them
were prone to accidental explosion when the operator
allowed the pressure to become too high, either
deliberately or through incompetence.
