Can the 6 screws at the midpoint of the valve in a reciprocating compressor be tightened?
The valve stem screw is used to tighten the valve cover, preventing the valve from moving within the sealed structure
Piston rod for the air valve, used to press the valve cover in place to prevent the air valve from moving around inside the sealing chamber
The set screw must not loosen; it needs to be tightened every six months
Those six bolts are used to hold the valve in place~~~~ They can be removed and replaced with clamps in order to adjust the load~~~~ You can look up more information on this topic~~~~ It seems unnecessary to tighten them that much~~~
Piston rod for the air valve, used to press the valve cover and thus secure the seal of the air valve
That is the valve cover set screw cap. What is being tightened inside is the valve cover set screw. This cap generally doesn’t loosen; it’s usually the set screw inside that becomes loose. One needs to remove the cap, tighten the set screw inside, and then tighten the cap again
It can be tightened; these are 6 set screw caps used to prevent leakage at the threads of the set screws, and tightening them can help if there is any air leakage.
The one inside is called the valve stem screw, which prevents the valve from moving; the one visible on the outside is called the screw cap, and it, together with the copper gasket, serves to prevent leaks
