DESIGN AND ANALYSIS OF GATE VALVE BODY AND SEAT RINGIAEME Publication
Gate valves are used when a straight-line flow of fluid and minimum restriction is desired. Gate valves are so named because the part that either stops or allows flow of fluid through the valve acts somewhat like the opening or closing of a gate and is called, appropriately, the gate. This gate valve is widely used in various industries like
refineries, petrochemical complexes, fertilizer plants, power generation plants (hydro
- electric, thermal and nuclear) steel plants and allied industries etc. for a various
process. The objective of this project is to perform a stress analysis and temperature distribution of valve body of the Gate Valve. The seat ring is welded with the valve body by using gas tungsten arc welding. A model of body and seat ring of Gate Valve
is developed in SOLID WORKS 2014, and analyzed in ANSYS 15. Gate valve stress

DIFFERENT TYPES OF FLOW CONTROL VALVES
1. BALL VALVE
A ball valve is a form of quarter-turn valve which uses a hollow, perforated and pivoting ball to
control flow through it. It is open when the ball\'s hole is in line with the flow and closed when it
is pivoted 90-degrees by the valve handle. The handle lies flat in alignment with the flow when
open, and is perpendicular to it when closed, making for easy visual confirmation of the valve\'s
status.
Ball valves are durable, performing well after many cycles, and reliable, closing securely even
after long periods of disuse. These qualities make them an excellent choice for shutoff and
control applications, where they are often preferred to gates and globe valves, but they lack their
fine control in throttling applications.
The ball valve\'s ease of operation, repair, and versatility lend it to extensive industrial use,
supporting pressures up to 1000 bar and temperatures up to 752 °F (500 °C), depending on
design and materials used. Sizes typically range from 0.2 to 48 inches (0.5 cm to 121 cm). One
disadvantage of a ball valve is that they trap water in the center cavity while in the closed
position. In the event of a freeze, the sides can crack due to expansion of ice forming. Some
means of insulation or heat tape in this situation will usually prevent damage. Another option for
cold climates is the \"freeze tolerant ball valve\". This style of ball valve incorporates a freeze
plug in the side so in the event of a freeze up, the freeze plug ruptures, (acts as a sacrificial disk),
thus making for an easy repair. Now instead of replacing the whole valve, just screw in a new
freeze plug.
2.GATE VALVE
A gate valve, also known as a sluice valve, is a valve which opens by lifting a round or
rectangular gate/wedge out of the path of the fluid. The distinct feature of a gate valve is the
sealing surfaces between the gate and seats are planar, so gate valves are often used when a
straight-line flow of fluid and minimum restriction is desired. The gate faces can be parallel, but
are most commonly wedge-shaped. Gate valves are primarily used to permit or prevent the flow
of liquids, but typical gate valves shouldn\'t be used for regulating flow, unless they are
specifically designed for that purpose. Because of their ability to cut through liquids, gate valves
are often used in the petroleum industry. For extremely thick fluids, a specialty valve often
known as a knife gate valve is used to cut through the liquid. On opening the gate valve, the flow
path is enlarged in a highly nonlinear manner with respect to percent of opening. This means that
flow rate does not change evenly with stem travel. Also, a partially open gate tends to vibrate
from the fluid flow. Most of the flow change occurs near shutoff with a relatively high fluid
velocity causing gate and seat wear and eventual leakage if u.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.
2. COMMON VALVE TYPES
A Ball Valve is a valve with a spherical disc, the part of the valve which controls the flow through it. The sphere has a hole, or port, through
the middle so that when the port is in line with both ends of the valve, flow will occur. When the valve is closed, the hole is perpendicular to
the ends of the valve, and flow is blocked. The handle or lever will be inline with the port position letting you “see” the valve's position. The
ball valve, along with the butterfly valve and plug valve, are part of the family of quarter turn valves.
Ball valves are durable and usually work to achieve perfect shutoff even after years of disuse. They are therefore an excellent choice for
shutoff applications (and are often preferred to globe valves and gate valves for this purpose). Ball valves are used extensively in industrial
applications because they are very versatile, supporting pressures up to 1000 bar and temperatures up to 752°F (500°C) depending on the
ball valve design and material. Sizes typically range from 0.2 to 48 inches (0.5 cm to 121 cm). They are easy to repair and operate.
OzLinc supplies full bore, reduced bore, L-Port and T-Port in 2 piece and 3 piece valves in nickel plated brass and full 316 stainless steel.
Gate Valves are also known as a sluice valve, is a valve that opens by lifting a round or rectangular gate/wedge out of the path of the fluid.
The distinct feature of a gate valve is the sealing surfaces between the gate and seats are planar, so gate valves are often used when a
straight-line flow of fluid and minimum restriction is desired. The gate faces can form a wedge shape or they can be parallel. Gate valves are
primarily used to permit or prevent the flow of liquids, but typical gate valves shouldn't be used for regulating flow, unless they are specifically
designed for that purpose. Because of their ability to cut through liquids, gate valves are often used in the petroleum industry. For extremely
thick fluids, a specialty valve often known as a knife valve is used to cut through the liquid
Butterfly Valves are valves which can be used for isolating or regulating flow. The closing mechanism takes the form of a disk. Operation
is similar to that of a ball valve, which allows for quick shut off. Butterfly valves are generally favoured because they are lower in cost to
other valve designs as well as being lighter in weight, meaning less support is required. The disc is positioned in the centre of the pipe,
passing through the disc is a rod connected to an actuator on the outside of the valve. Rotating the actuator turns the disc either parallel or
perpendicular to the flow. Unlike a ball valve, the disc is always present within the flow, therefore a pressure drop is always induced in the
flow, regardless of valve position.
A butterfly valve is from a family of valves called quarter-turn valves. In operation, the valve is fully open or closed when the disc is rotated a
quarter turn. The “butterfly” is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the
passageway. When the valve is fully open, the disc is rotated a quarter turn so that it allows an almost unrestricted passage of the fluid. The
valve may also be opened incrementally to throttle flow.
A Check Valve, Clack Valve, Non-Return Valve or One-Way Valve is 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, check valves generally are very small, simple, or inexpensive. 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.
An important concept in check valves is the cracking pressure which is the minimum upstream pressure at which the valve will operate.
Typically the check valve is designed for and can therefore be specified for a specific cracking pressure.
A Globe Valve, different from ball valve, is a type of valve used for regulating flow in a pipeline, consisting of a movable disk-type element
and a stationary ring seat in a generally spherical body.
Globe valves are named for their spherical body shape with the two halves of the body being separated by an internal baffle. This has an
opening that forms a seat onto which a movable plug can be screwed in to close (or shut) the valve. The plug is also called a disc or disk. In
globe valves, the plug is connected to a stem which is operated by screw action using a hand wheel in manual valves. Typically, automated
globe valves use smooth stems rather than threaded and are opened and closed by an actuator assembly.
