顺序阀和溢流阀的区别在哪?
Where is the difference between a sequence valve and relief valve?
Sequence valve and sequence valve from the structure points can be divided into two kinds of, pilot operated and direct acting and
pilot operated frequently used in super high pressure hydraulic system, and straight acting more for low pressure systems.

Coming up from drainage way points, sequence valve can be divided into inside leaking and leaked again. Leakage is not to say that
the hydraulic oil leaking and drain into the tank, but is leaked through a separate line of the petrol tank, and internal drainage
directly from the oil outlet can row the petrol tank. Because has a certain pressure function, so a lot of people will get mixed up
the overflow valve and sequence valve, in fact, there are still a lot of difference between them, such as:

 first, sequence valve of higher precision, because it is a series of components in hydraulic system to control the non-standard
order action, can't be a little deviation.

Second, the sequence valve drainage quantity is less, this also is in order to guarantee the precision of the sequence valve.
Third, the overflow valve is internal drainage, and the order of the leaked type of valve is used to drain alone leads to a path.
Fourth, the function is different, the overflow valve is to prevent the pressure is too high, there is no other function, so the
emission of oil there would be no more effect, direct return to the fuel tank, and the sequence valve leakage of hydraulic oil can
in some cases the load.

Fifth, the working principle is different, the overflow valve inlet pressure is constant, outlet pressure decreases, and the sequence
valve is according to the requirement of the outlet pressure, directly from the inlet pressure began to adjust.
