Distinguishing between the valve plates in the suction and discharge valves of reciprocating compressors and the buffer plates in those same valves
Thread Content
A valve has only one valve disc, while a buffer disc has two identical ones
1. To distinguish between the intake and exhaust valves of a compressor, it is first necessary to understand the working principle of these valves as well as their mechanism； 2. The components of a valve include the valve body, valve disc, spring, and damping element; in some cases, there is also a damping spring ； 3. There are many ways to distinguish them; one method is to rely on the working principle of the air valve – by following the direction in which the spring and the valve disc move, a screwdriver can be used to press on the valve disc. If it moves under pressure, that indicates the direction in which it operates ； There is another simple method: the direction of the fixing bolts for the valve body assembly should always be toward the installation direction.
