Document Type and Number:
WIPO Patent Application WO/2022/111252
Kind Code:
A1
Abstract:
A composite sealing gas valve. The composite sealing gas valve comprises a valve body (1), a valve element assembly, a pressure spring (4) and a valve cover (5). The valve body (1) comprises a valve element cavity (11), a valve element seat (12) arranged at the closed end of the valve element cavity (11), and a gas guide hole (13) provided in the valve element seat (12); the valve element assembly comprises a valve element (2) and a valve element fixing seat (3); the valve cover (5) is screwed into the valve element cavity (11), and the pressure spring (4) matches the valve element assembly and the valve cover (5); and one end of the valve element assembly is provided with a curved-surface-shaped head (21) and an annular protrusion (22) surrounding the curved-surface-shaped head (21), the curved-surface-shaped head (21) extending into the gas guide hole (13) to form annular line contact sealing with the valve body (1), and the annular protrusion (22) being plane-sealed with the valve body. The gas valve can reduce the rising amplitude of the valve element assembly relative to a set gas pressure value.
