Document Type and Number:
WIPO Patent Application WO/2019/080365
Kind Code:
A1
Abstract:
Disclosed are a valve rod connecting structure for a sealing water valve, and a sealing water valve. The valve rod connecting structure for a sealing water valve comprises a fastener (1), a valve rod (2) used for controlling the opening and closing of a valve body control mechanism, and a moving plate (3) provided in an inner cavity of a sealing water valve body as a part of the valve body control mechanism to form fluid passages of different radial sizes by means of running fit. The valve rod (2) is assembled onto a valve body control mechanism assembling opening by means of the fastener (1). The moving plate (3) is connected to the valve rod (2) and rotates along with the valve rod (2). The valve rod (2) is sealed in a chamber formed by attachment and sealing fit between the upper end face of the moving plate (3) and the lower end face of the fastener (1). Water flow in the inner cavity of the valve body is enabled or disabled by means of the running fit between the moving plate and a static plate directly provided in the inner cavity of the valve body, so that sealing links are fewer, the dynamic sealing reliability is high, and the service life of the sealing water valve is long.
