Title:
SEALING STRUCTURE OF VALVE BODY, VALVE AND CFLVV VALVE
Document Type and Number:
WIPO Patent Application WO/2022/110533
Kind Code:
A1
Abstract:
A sealing structure of a valve body, a valve and a CFLVV valve. A sealing part positioned between a large valve core (5) and a top surface of an inner cavity of the valve body (1) is arranged in the inner cavity of the valve body; when a large discharge port (2) needs to be closed, the large valve core (5) moves to a closing position and cooperates with the sealing part to close the large discharge port (2) and form a first communication channel communicating with a small discharge port (3); and when the small discharge port (3) needs to be further closed, a small valve core (6) is lifted to seal the first communication channel, so that the small discharge port (3) is closed. Only one sealing part is needed to realize the opening and closing of the two discharge ports, respectively, by the two valve cores, thereby solving the problem that sealing parts of an existing combined valve need to be separately arranged for two valve cores, respectively.
