Poppet valves are recommended up to 15 MPa differential pressure or 30 MPa dischargepressure and 600rpm.
Plate Type Valve
Reciprocating Compressor Basics Components
The plate type valve contains concentric rings of valve plates. The concentric ring
valve plates are a single element. Since the valve plate is made of a single element,
flow control is much easier when compared to other types of valves.
The stress act on the valve plate is much higher than the Poppet valve. These type of
valves are widely used compressor handling of Oil-free gases.
Cross Head十字头
All industrial compressors are equipped with crosshead. The crosshead is used to
guide the piston in the cylinder bore. The following are the advantage of the crosshead.

The crosshead pin should have a replaceable bush bearing.

Connecting Rod连杆
Purpose of the connecting rod is to connect the crankshaft and the crosshead. The
connecting rod converts the rotary motion into reciprocating motion. The connecting
rod bolts and nuts shall be securely locked with cotter pins or wire after assembly.
Like Crankshafts, the connecting rod has drilled hole for oil passage.

Radial Ring or Pressure Breaker Ring径向环或压力断路器环
The radial ring or pressure breaker ring is cut into three segments so that each cut
lies on the side of a radial direction of the ring. The cuts in the ring are used to
break down the pressure act on the ring. The radial ring is the first ring of road
packing to face the cylinder pressure.
For lubricated service, metallic rings such as cast iron or bronze as well as non-metallic materials such as filled nylon are used. Nowadays the compressor manufacturers preferred non-metallic materials because of less weight and lower frictional force when compared with metallic rings.
