Abstract
The utility model discloses a hydraulic drive flat valve with a manually-closing device. The hydraulic drive flat valve comprises a valve body, a valve cover, a valve rod, a valve plate and an actuator. A screw type actuator and a hydraulic drive type actuator of a traditional flat valve are combined into a whole, under the condition of pipeline emergency in a field, hydraulic pressure can be conveniently and quickly released only by using a spanner to unscrew plugs on discharge holes of a hydraulic oil cylinder body, and the plugs can be manually closed. In addition, a screw type drive assembly is arranged in a sealed hydraulic drive piston cylinder body, so that the product efficacy loss caused by corrosion and blockage due to the fact that the manually-operated type drive assembly is exposed to the severe working condition environment is avoided.
