Advantages of Relief Valve
A relief valve is a safety device that is used to prevent overpressurization in a system.
1
>>
Relief valves are used in a variety of applications, including boiler systems, pressure vessels, and piping systems.
2
>>
Relief valves are designed to open at a predetermined pressure in order to release excess pressure from the system.
3
>>
Relief valves can be either manually operated or automatically operated.
4
>>
Relief valves are an important safety feature in many industrial and commercial applications.
5
Low lift safety valve - The actual position of the disc determines the discharge area of the valve.
Full lift safety valve - The discharge area is not determined by the position of the disc.
Full bore safety valve - A safety valve having no protrusions in the bore, and wherein the valve lifts to an extent sufficient for the minimum area at any section, at or below the seat, to become the controlling orifice.
Conventional safety relief valve - The spring housing is vented to the discharge side, hence operational characteristics are directly affected by changes in the backpressure to the valve.
Balanced safety relief valve - A balanced valve incorporates a means of minimising the effect of backpressure on the operational characteristics of the valve.
Pilot operated pressure relief valve - The major relieving device is combined with, and is controlled by, a self-actuated auxiliary pressure relief device.
Power-actuated safety relief valve - A pressure relief valve in which the major pressure relieving device is combined with, and controlled by, a device requiring an external source of energy.
Components of Conventional safety relief valve
Cap - The safety valve cap, which may be threaded or fastened to the bonnet with a bolt, is the top portion that conceals the adjustment screw.
The bonnet is the valve's central section and contains a stem, spring, buttons, and guide plate. This device could be open or closed.
Body - The body is the bottom-most part and contains a disc, disc holder, locking nut, and nozzle blow-down ring.
Adjustment Screw The calibration of a pressure safety valve at a given fixed pressure is attained by adjustment.
Stem - This component distributes the spring force to the disc assembly while also aligning the parts.
Spring and spring buttons - A spring will keep the valve closed and the spring button can evenly distribute pressure.
Lift lever - Manual pressure release is achieved via the lift lever
Disc and Disc Holder - This device would be impacted by process pressure and susceptible to galling, erosion, and pitting.
Nozzle - The process fluid enters the valve through a channel called a nozzle. They come in a variety of styles, including fully threaded, and removable, partially threaded and removable, partially welded in the valve body, and partially pressed and removable.
Storage and transportation and installation should be done with care.
The valve should be protected from foreign substances and dust until the installation time.
The valve shaft should be mounted so that it is vertical.
No valve should be placed between safety valve and pressure vessel.
The safety valve must have an easily accessible area where installed.
Safety valve outlet pipe should be opened at the shortest path to the atmosfere.
The relief valve should be inclined in the direction of the outlet pipe.
If the safety valve is uplifted, then one of the options should be to design drainage, pot (diameter of inner pipe), diameter enlargement in order to get water that may occur at the elbow part.
Separate outlet line for each safety valve. If it is going to enter the exhaust pipe; the distance between the safety valve output and the exhaust must be at least 4 meters.
