日本油研單向節(jié)流閥特性,YUKEN單向節(jié)流閥技術(shù)特性
The throttle valve has no flow negative
feedback function and can not compensate for
 the instability caused by the load change.
It is only used when the load is not changed or the speed stability is not high
The performance requirements for the throttle valve are:
· Flow adjustment range is large, the flow of a pressure change smooth;
· Leakage within the small, if the leakage of oil leakage, the external leakage should be small;
· Adjust the torque is small, action sensitive.
Throttle valve shape structure and the cut-off valve is no different,
but they open and close the shape of the pieces are different.
Is a valve that controls the flow of fluid by changing the
throttling section or throttling length. The throttle valve and
check valve can be combined into a one-way throttle valve.
 Throttle valve opening and closing parts are mostly conical flow line type,
through which to change the channel cross-sectional area to adjust the flow and pressure.
 The throttle valve is used to reduce the medium pressure when the pressure drop is extremely large.
The velocity of the medium between the throttle valve and the valve seat is so
large that the surface of these parts is quickly damaged -
 the so-called cavitation phenomenon. In order to minimize
the impact of cavitation, the valve with anti-cavitation
materials (alloy steel) and made of the top angle of 140 to 180 streamlined cone,
which can make the valve flap can have a large opening height,
generally not recommended In the small gap under the throat.
Throttle and one-way throttle valve is a simple flow control valve,
in the quantitative pump hydraulic system,
