Zusammenfassung:	The utility model relates to a valve with a valve rod capable of moving at a high frequency. According to the valve, the valve rod is unlikely to swing, and a valve clack is unlikely to move transversely. An upper copper sleeve is fixed in a center hole in a valve cover, is arranged outside the center of the valve rod in a sleeving mode and is in sliding connection with the middle of the valve rod. A connection rod is fixed to the bottom of the valve clack, an installation hole is formed in the middle of the connection rod, and the upper portion of a guide rod is inserted into the installation hole. A nut is in threaded connection to the outer wall of the connection rod to make the upper portion of the guide rod fixed in the installation hole in the connection rod. The guide rod is coaxial with the valve rod. A lower copper sleeve is fixed to a guide seat and arranged outside the lower portion of the guide rod in a sleeving mode, is in sliding connection with the lower portion of the guide rod, and is coaxial with the upper copper sleeve. When the valve is opened and closed, the valve rod moves vertically in the upper copper sleeve, the guide rod moves vertically in the lower copper sleeve, the valve rod cannot move out of the upper copper sleeve, and the guide rod cannot move out of the lower copper sleeve. The guide seat is fixed to an inlet runner or a valve orifice.
