Compact type low-power-consumption rapid-response leakage-free hydraulic stop valve

The invention discloses a compact type low-power-consumption rapid-response leakage-free hydraulic stop valve. The compact type low-power-consumption rapid-response leakage-free hydraulic stop valve comprises an electromagnetic excitation device, a thrust actuation device, a hydraulic stop device and a manual control device, wherein the electromagnetic excitation device surrounds the thrust actuation device and is fixed on the thrust actuation device through a tightening nut; the thrust actuation device is connected with the hydraulic stop device through threads and is tightened by an open spring cushion; and the manual control device is arranged at the tail end of the thrust actuation device. The hydraulic stop valve is compact in structure, low in system power consumption and rapid in response, is capable of meeting accurate and force control requirements, and also has the advantages of no leakage, high usage pressure and strong anti-pollution capability. 本发明公开了一种紧凑型低功耗高速响应无泄漏液压截止阀，由电磁激磁装置、推力作动装置、液压截止装置及手动控
