Document Type and Number:
WIPO Patent Application WO/2022/110532
Kind Code:
A1
Abstract:
A valve, a multifunctional combination valve, and a CFLVV valve. A valve core accommodating cavity is provided in a valve body, and a first inflow channel, a second inflow channel, a first discharge port and a second discharge port in communication with the valve core accommodating cavity are provided. A first valve core assembly and a second valve core assembly that can independently slide vertically are provided in the valve core accommodating cavity (19) for opening or closing the first discharge port (13) and the second discharge port (14). A pressure maintaining part is connected to the second discharge port (14) and contains a certain opening pressure; after the first valve core assembly closes the first discharge port (13), and after the valve core accommodating cavity needs to reach a certain pressure value, the pressure maintaining part opens the second discharge port (14), and a fluid flows out from the second discharge port (14). The two valve core assemblies can achieve different functions and do not affect each other, and a combination valve capable of satisfying different technical requirements by respectively adjusting the performance of the two valve cores solves the problem that two valve cores in an existing combination valve may affect each other.
