Pneumatic Systems Objective Questions

Function of pneumatic valve is to control the pressure, flow rate and direction of air flow in pneumatic circuits. Directional control valves start, stop or change the direction of flow in compressed air applications. Three way DCV are used to control single acting cylinders. Four way DCV are used to control double acting cylinders. The check valves are used to allow free flow of compressed air in only one direction and it prevents the flow of compressed air in the opposite direction.

Since check valves blocks the reverse flow, they are also known as Non-return valves. Shuttle valves , also known as double check valves, are used when control is required from more than one power source. It can be used as OR gate fluid logic control valve. It is used with spring return single acting cylinder to increase the piston speed of the cylinders. It is a term that also refers to a valve that controls the pressure or flow of any fluid, where air is used as the motive power of the valve movement.

Like above the valve can be one of many different types including globe control valves that have two or three ports. So when talking about Pneumatic Control valves , I thinks of any valve where air is the control signal, regardless of the process fluid.

Subsequent to repairs and heat treatment and prior to initial operation or commissioning of any plant it has to be ensured that there is no evidence of leakage by Pressure Testing. In the process Industry, two methods are widely used for pressure testing of piping or equipment. They are. Hydro test or Hydrostatic test is a type of pressure test performed on piping and pressure vessels to check system integrity under pressure condition. A hydrostatic test is performed by using water as the test medium. The pneumatic test is a type of pressure test for checking system integrity under the pressurized condition and applied to systems where the hydro-static test is difficult to apply. A pneumatic test uses air, nitrogen, or any non-flammable and non-toxic gas.

Он застонал. Проклятые испанцы начинают службу с причастия. ГЛАВА 92 Сьюзан начала спускаться по лестнице в подсобное помещение. Густые клубы пара окутывали корпус ТРАНСТЕКСТА, ступеньки лестницы были влажными от конденсации, она едва не упала, поскользнувшись. Она нервничала, гадая, сколько еще времени продержится ТРАНСТЕКСТ.

Единственный терминал в шифровалке, с которого разрешалось обходить фильтры Сквозь строй, принадлежал Стратмору. Когда коммандер заговорил, в его голосе звучали ледяные нотки: - Мистер Чатрукьян, я не хочу сказать, что вас это не касается, но фильтры обошел.  - Очевидно, что Стратмор с трудом сдерживает гнев.
