Abstract

The invention discloses a magnetically-driven valve device. The magnetically-driven valve device comprises a power source, driver and a valve body which are connected in sequence, wherein a valve body flange is fixed to the other end of the valve body in a sealed mode, a drive shaft and a gate plate which are connected movably are arranged in a channel of the valve body, the drive shaft is connected with the driver, a magnetic flange penetrates through the side wall of the valve body to be arranged, a through medium channel penetrating through the magnetic flange, the gate plate and the valve body is radially formed, and the power source drives the driver to drive the gate plate to move in the channel of the valve body. The magnetically-driven valve device adopts a magnetic pair made of a high-temperature-resisting permanent-magnet material to provide the acting force required by valve sealing without a backpressure condition and adopts a high-temperature-resisting high-pressure corrosion and radiation resistance sealing pair to achieve planar and linear-contact rigid sealing of a valve. Reliable outer sealing can be achieved by adopting connection modes including the driver, static sealing structures of sealing rings and flanges, welding and the like. Smooth passing of a fluid and a large-particle medium can be achieved by adopting the full-sized medium channel.

Description

technical field [0001] The invention belongs to the technical field of valves, and in particular relates to a magnetically driven valve-like device. Background technique [0002] The nuclear power and petrochemical fields have very high requirements for the internal and external sealing of valves working under high temperature, high pressure, strong corrosive, strong leakage medium and strong radioactive working conditions, but they are subject to conditions such as sealing materials, sealing structures, radioactivity and force. It is difficult to realize the full sealing of the valve, especially in the medium of extremely small molecules such as helium, and the inner sealing is difficult to meet the requirements. [0003] At the same time, for the material conveying pipeline system, in addition to the strict requirements on the internal and external sealing of the valve, the problem of the smooth passage of larger particle size materials such as high-temperature gas-cooled ...
