overflow valve


Relief valves in the form of the structure and type of moving into straight-pilot, and it's up in Hydraulic Pump export guarantee system, or limitation of the maximum pressure constant pressure, sometimes adjacent to import components in the implementation of the components of its security role. Straight moving type relief valves, mainly valve disc, valve body,, spring-loaded, roof, regulation pole, conditioning nut, and other integral parts.

Pilot valves and pilot-type relief valves are the main valves of two parts, pilot valves for cone valve, the flow is a small direct action type relief valves. With import pressure relief valves, pilot vavel disc role in the fluid pressure Fx attendant increase, when more than equal to Fx Pt2, pilot valves valves mouth opened, the pressure relief valves to import oil by damping hole, Pilot valves valves mouth overflow relief valves to export, and then back to the fuel tank. Imported oil pressure relief valves to the main valve valves mouth overflow back containers. Main valves valves mouth open for some time, pilot valves and the valve Faxin Faxin respectively in the balance of power, pressure flow valves meet the equation mouth, and the main valve to the pressure of a determined value of imports.
