Q: the reversing multi-way valve unloading performance profiling a: multiple directional control valves, because the structure is compact, easy to focus on driving, short circuit, the merits of small pressure loss, in agricultural machinery, engineering machinery hydraulic components more the implementation of the widely used in the system. Multiple combination often with one-way valve, reversing valve of hydraulic controlled check valve, safety valve, such as group as a whole, because of this but its reversing function, also has the system pressure limiting, unloading, lock of actuators, and other functions, especially the unloading function is shut. Cuts in agricultural machinery, especially the joint machine, the widespread use of multiple combination directional control valve, the components of interrupt office, hydraulic system often in unloading condition, the stand or fall of unloading performance greatly impact on the system, if the unloading pressure high, can + 羭 big losses, system temperature, can't even make the system normal office. Because this is indispensable to the unloading performance profiling, and reasonable default unloading valve. Unloading into channel and pressure valve was established. Unloading, each valve core position in the fence, the oil in the oil source to a dedicated permeate each valve oil discharge back to the fuel tank, unloading oil permeate each directional valve. When the President of valve all the way inside office ( Where the unloading oil duct truncation) 。 Oil source of oil is from which the reversing valve in the stem of actuators, office pressure volume pressure valve is framed by the picture. See fit and use this kind of unloading form strengths is the directional valve stem from the vertical position and office location in the process of moving, unloading oil duct is gradually being closed, oil amount increase gradually, components in the implementation of the system pressure is increasing, actuators began to work safe and secure, no impact, and constant speed control performance, a Marine valve pressure valve has simple structure. Long is the want of unloading oil, pressure loss is big, especially the reversing valve because for a long time, more MaoJian ills, this kind of unloading form for more because fewer occasions. Unloading valve and relief valve, pilot operated pressure valve, the valve is unloading valve and relief valve, sometimes overflow valve. When unloading the stem oil permeate each directional Industrial Valves, with the unloading oil. When multiple directional control valve is in the fence position, unloading valve stem oil way ( As shown in figure 1 and figure 2 b) Permeate each directional Industrial Valves and fuel tank connected. When unloading, most oil unloading, short channel, low pressure loss. Office as a reversing valve all the way, then truncate the stem oil duct, oil source to oil from reversing valve in actuators out of office, the office of pressure volume by the pilot valve stem. The system pressure for pilot testing. This kind of unloading form, even if the reversing valve road times increase, just stem oil increase, small as unloading pressure increases, exploring to maintain low unloading pressure, the unloading form for more hands move to the valve, unloading. 。 Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.
