Question

 ______ valves are provided in reciprocating compressors.
1. Simply Supported
2. Plate
3. Poppet
4. Solenoid

Answer 1

Correct Answer - Option 2 : Plate

Explanation:

• Plate type or Reed type valves are used in reciprocating compressors.
• These valves are either floating or clamped, usually, backstops are provided to limit the valve displacement.
• Spring may be provided for smooth return after opening or closing
• The piston speed is decided by valve type. Too high speed will give excessive vapor velocities that will decrease the volumetric efficiency and throttling loss will decrease the compression efficiency. 
•  Plate valves are designed to withstand high pressure and dirty gas applications. 
•  Solenoid valve is control units which, when electrically energized or de-energized,  either shut off or allow fluid flow.
• A Poppet valve is typically used to control the timing and quantity of gas or vapor flow into an engine.
