Summary: | The invention relates to a plug-in mounting type long-service-life zero-leakage hydraulic locking valve which is a compact integrated high-pressure-resistant zero-leakage hydraulic locking device. The valve body is installed in a servo mechanism valve body and used for communicating an oil pump with a servo actuator. In the shutdown process of the servo mechanism, the oil pump does not work, the hydraulic locking valve does not work, the valve element II is in a closed state, an oil way between the servo actuator and the oil pump is cut off, oil in the servo actuator is sealed, and a piston rod of the servo actuator is fixed to the middle position, cannot swing at will and is located in a locking loop. When the control cavity is not filled with oil, the function is the same as that of a common one-way valve, forward circulation and reverse cut-off are achieved, and when the control cavity is filled with oil, the valve element is opened, and oil can flow in the forward direction and the reverse direction.
