Description

Valve with pressure difference compensation structure Technical Field The invention relates to the technical field of valves, in particular to a valve with a differential pressure compensation structure. Background The valve is a pipeline accessory for opening and closing a pipeline, controlling the flow direction, adjusting and controlling the parameters of a conveying medium. The valve is a control component in the system and has the functions of stopping, guiding flow, preventing backflow, stabilizing pressure, shunting or overflow pressure relief and the like. The current ball valve for hydraulic system is at the in-process of opening, because the pressure differential at ball valve both ends is great, leads to the ball valve when opening, and the pivoted resistance of case of ball valve is great to lead to the handle of ball valve to pull comparatively laboriously, leads to the ball valve to open very laboriously, and the pressure differential is too big also can cause great impact to hydraulic system when opening, influences hydraulic system's safety in utilization.
