Disclosed is a position feedback device of a shock-resisting automatic valve. The position feedback device of the shock-resisting automatic valve is mounted at the top end of a valve body or an operating mechanism and comprises proximity switches, a fixing support and coaxial baffles. The coaxial baffles are welded to the portion of the valve core shaft of the automatic valve or the shaft of the operating mechanism, which extends out of the valve core and accordingly can rotate along with a valve core; the fixing support is welded on one side of the valve body; the two proximity switches are mounted on the fixing support in parallel and accordingly can be on the same plane with the coaxial baffles. Due to the fact that the feedback switches are in a non-contact state, the position feedback device of the shock-resisting automatic valve solves the problem of malfunction due to shock; according to the different requirements of a control system, the witches can be provided with appropriate voltage levels in appropriate wiring manners, so that the reliability of the system can be greatly enhanced.
