AI Technical Summary
In existing online inspection devices for sealed breather valves, the plastic-lined sealing surface is easily damaged due to local stress concentration, and the sealing status of the valve disc is not easy to determine, which leads to the risk of over-tightening of the plastic lining layer.
A plastic lining layer is placed on the mounting base surface of the valve seat, and a sealing fit with different widths is formed by the second annular sealing surface on the valve disc side and the first annular sealing surface on the valve seat side. Combined with the transmission component and the indicator component, the valve disc sealing position is indicated.
It reduces the risk of wear and peeling of the plastic lining, improves sealing reliability and service life, and makes it easier to judge the sealing status and avoids over-tightening.
