Effect of Spring on Operating Characteristic of Spring Loaded Safety Valves

چکیده
It IS well known about the principle of popping at spring loaded safety valves. It is also essential that the valves should operate surely judging by their purposes. In this study, operating tests have been carried out systematically using a safety valve, which belongs to lift type for air service and has a nominal size of 1 inch. In the beginning, we focussed on coiled spring whicl1 is one of the most important factors for balance of forces at safety valves. The influence of spring constant of coiled spring on operating characteristic of the valves is reporled in this paper. And, the influence of spent coiled spring on it is also reported in deta i I .

Influence of Pipeline Operating Pressure on Value Setting of Automatic Control Valves at Different Pressure Drop Rates
When a natural gas pipeline ruptures, the adjacent upstream and downstream automatic control valves (ACV) should close quickly to prevent leakage or explosion. The differential pressure set point (DPS) at each valve location is the main criteria for value setting in ACV actions. If the DPS is not properly adjusted, the ACV may mistakenly close or it may not take any actions at a proper ti...

Direct acting spring loaded pressure relief valve is one of the most important devices to ensure security to pipeline oil transport. However, relief valves’ manufactures generally only provide information on valve characteristics under full opening stage, which is obtained under steady state regime, therefore, valve and flow’s transient behavior are neglected. Understanding the transient behavi...

When a natural gas pipeline ruptures, the adjacent automatic line control valves (ALCVs) should close quickly to prevent leakage or explosion. The differential pressure set point (DPS) at each valve location is the main criteria for value setting in ALCV action. If the DPS is not properly adjusted, the ALCV may mistakenly close or it may not take any action at proper time. This study focused on...
متن کاملThe Dynamics Of Reciprocating Compressor Valve Springs
The valves in reciprocating compressors use springs to control the timing of the valve closing. These springs are subjected to dynamic loading by the motion of the valve element. The element motion is periodic, but includes rapid acceleration and deceleration. It can therefore excite a wide range of frequencies in the spring. The resulting spring surge creates high stresses and is a major contr...
متن کاملMetabolic energy expenditure during spring-loaded crutch ambulation.
CONTEXT Individuals using traditional axillary crutches to ambulate expend approximately twice as much energy as individuals who perform able-bodied gait. A relatively novel spring-loaded crutch now being marketed may reduce metabolic energy expenditure during crutch ambulation. This idea, however, had not yet been tested. OBJECTIVE To determine whether the novel spring-loaded crutch reduces ...
