Description

Technical Field

[0001] The utility model relates to a pressure and flow regulating valve for a hydraulic booster pump used in mining, in particular to a device capable of regulating the pressure and flow in a liquid supply system. Background Art

[0002] At present, most of the pressure and flow regulating valves in mining hydraulic systems are gate valves, which control pressure and flow by raising and lowering the height of the gate in the valve.

Firstly, the flow control is not accurate, and secondly, the force on the gate is large, making it difficult to easily turn the handwheel. However, there is currently no device that can both accurately control the flow and easily turn the handwheel to solve this problem. Summary of the Invention
