Reciprocating compressor
Thread Content
Which ones in the diagram are the valve caps and valve seats of a reciprocating compressor valve?
1. Intake valve seat； 2. Intake valve cover. 3. Exhaust valve seat ； 4. Exhaust valve cover. This can also be called a check valve; the key is the direction of use. The most straightforward way to determine the direction is to check whether the spring points toward the exhaust side; by using a screwdriver to press on the valve disc, it is possible to determine the direction. Remember, if you are unsure, do not install it to avoid accidents. For reference.
A compressor is used to compress gases, reducing their volume as a result. Based on this principle, the one with a larger diameter should be the inlet, while the one with a smaller diameter is the outlet.

You’re too kind:D I come from a worker background, so I’m just a bit better at on-site work; P
