Description

Technical Field

Therefore, the quality of the compressor intake valve directly affects the operation effect and life of the compressor.

When the compressor intake valve is used, the valve body 1 is activated, and the first sealing plug 2 and the second sealing plug 3 are inserted upward into the silencer cylinder 401. First, the second sealing plug 3 contacts the rubber gasket 503.
