Plate valves are recommended up to 20 MPa differential or 40 MPa discharge pressureand 1800 rpm.
Ring Type Valve
Reciprocating Compressor Basics Components
As the name implies the ring-type valve consisting of concentric ring valve uses one
or more relatively narrow rings arranged concentrically about the centre line of the
valve (see Fig ). These valves have the advantage of a low-stress level due to the
lack of stress concentration points. It is difficult to maintain uniform flow control
across the ring-type valve.
Ring valves are recommended up to 30 MPa differential or 60 MPa discharge pressure
and 600 rpm.
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 crankshaft is connected to drive, to transfer the rotary motion.
When force lubrication is used, drilled oil passage is provided in the crankshaft.

The packing rings are the important element of rod packing assembly. The below-listed
packing rings are widely used in a reciprocating compressor.

Backup Ring支承环
The construction of the backup ring is similar to the radial ring. As the name
indicate this type of ring is used to backup all the rings when using in the high-
pressure application.
Compartments in the distance piece collect and control packing leakage when the gas is toxic or flammable. The leakage can be direct to a flare or buffer inert gas is used to prevent the toxic gas leakage to the atmosphere.
