The utility model discloses a hydraulic wear-resistant gate valve, including the main valve of the wear-resistant gate valve and the hydraulic cylinder component that drives the main valve of the wear-resistant gate valve. The main valve of the wear-resistant gate valve consists of a valve body, a gate, a valve seat, a valve cover and a valve stem. The gate is set in the body of the valve body, the valve cover is fixed above the valve body, and the stem is set inside the valve cover and the stem is one. The end is connected with the gate plate. The other end of the stem is connected with the power output end of the hydraulic cylinder assembly. The seat is mounted on both sides of the upper and lower ends of the valve body and contacts with the two sides of the gate to form a sealing surface. The outside of each valve seat is equipped with a adjusting pad. The outer end of each adjustment cushion is equipped with a compression spring, and the outer end of the compression spring is adjusted with the adjusting screw. Fixed. The valve seat of the hydraulic wear-resistant gate valve of the utility model has spring prepressure and automatic compensation to form a double-sided forced seal. When the seal face is found to wear for a long time, only the adjusting screw and spring on both sides of the valve seat should be loosened, and a little bit of rotation is used when closing, and the automatic compensation and reliable seal can be realized, and the service life can be extended.
