Reciprocating Compressor Valves Assignment Flashcards
What are the four main components of a compressor valve?
Seat
Guard
Sealing Elements
Assembly Elements
What is the distance a valve opens called?
Lift
Valve flutter is caused by?
Excessive Lift
What are 3 advantages of a synthetic sealing elements?
- Less Noise
- Reduced seat wear
- Good for oil free applications
What is the main advantage of a V shaped sealing element?
Better Flow
Which valve offers the least restriction to flow?
Concentric Ring Valve
Discharge valves generally need more maintenance than suction valves.
True;
more pressure on discharge, more wear is my theory
Which valve is best suited when there may be liquids in the gas stream?
Poppet Valve
Which valve is best suited for high-speed applications?
Dampened Disc Valve
True or False
Only replace the springs that are broken when repairing a compressor valve.
False, replace them all
What measurements are necessary when inspecting a channel valve: (3)
- Valve Lift
- Spring End Clearance
- Spring Side Clearance
Filling a valve with a liquid is a precise way to check valve sealing.
False; not precise because this test “Leak test” does not simulate the conditions found inside the compressor
What could cause excessive rod loading?
Installing the valves incorrectly
(backwards, or mixing up suction and discharge valves)
True or False;
Compressor Valves are opened by the reciprocating action of the piston.
False;
pressure differential opens the valves
True or False;
Leaking suction valves can result in increased discharge valve temperatures.
True
