A differential pressure balanced oil drain valve, a control valve assembly, and an electric pump station
This utility model relates to the field of horizontal jack manufacturing technology, and in particular to a differential pressure balanced oil discharge valve, a control valve assembly, and an electric pump station. The differential pressure balanced oil discharge valve is the core component for achieving smooth jack descent, and includes a valve body, a valve core assembly, a pressure balancing mechanism, and a drive assembly. The valve body has a first oil passage and a second oil passage; the inner valve core of the valve core assembly has a pressure balancing channel, and an elastic reset element provides initial sealing pre-tightening force; the pressure balancing mechanism seals the pressure balancing channel through a sealing body. The drive assembly employs a two-stage control: the first stage pushes the pusher to open the sealing body, initially connecting the first and second oil passages, balancing the oil pressure, and reducing the pressure difference of the inner valve core; the second stage directly acts on the inner valve core, causing it to overcome the pre-tightening force to fully connect the first and second oil passages, achieving smooth hydraulic oil return, ensuring stable and vibration-free jack descent, while reducing operating force and improving safety and convenience.
