Description
The pressure reducing valve of the excavator pressure control valve is a pressure control valve that makes the outlet pressure (secondary pressure) lower than the inlet pressure (primary pressure). Pressure reducing valves are widely used in clamping systems, lubriion systems and control systems of various hydraulic equipment. The pressure reducing valve is divided into three types: fixed value, fixed difference and fixed ratio; the most common of which is fixed value pressure reducing valve. If not specified, the pressure reducing valve is usually a fixed value pressure reducing valve. According to the installation structure, it can be divided into superimposed type, direct installation type and pipe type pressure reducing valve; in general, the pipe type is less used. According to the working form, it can be divided into two types: pilot type and direct-acting type. The pressure reducing valve is generally loed at the branch interface of the actuator; the pressure reducing valve is mainly used to reduce the pressure of a branch oil circuit of the hydraulic system, so that the branch pressure is lower and stable than the main oil circuit pressure, within the range of the set pressure. , the pressure reducing valve is also closed like the overflow valve. However, as the system pressure increases, when the pressure set by the pressure reducing valve is reached, the pressure reducing valve opens, and part of the oil will return to the fuel tank through him (at this time, there is a certain pressure of oil returning to the fuel tank, and the oil temperature of the fuel tank will rise) , the oil pressure of this branch will not rise. It plays the role of decompression and voltage stabilization for this branch.
