material:
The medium flows between the throttle valve and the valve seat,
So that the surface of these parts 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 the top angle of 140 to 180 streamlined cone,
This can also make the valve flap can have a large opening height,
generally not recommended in the small gap under the throttling.
Ambient temperature range + 0 ° C / + 80 ° C
The performance requirements for the throttle valve are:
· Flow adjustment range is large, the flow of a pressure change smooth
Shell aluminum, anodized
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 and one-way throttle valve is a simple flow control valve,
In the quantitative pump hydraulic system,
throttle valve and relief valve can be composed of three kinds of throttle speed control system,
That is, into the oil flow throttling speed control system,
return to the oil flow throttling speed control system and bypass throttling speed control system.
Throttle valve no flow negative feedback function,
can not compensate for the load caused by the instability caused by the speed,
Generally only for the load changes little or less stability requirements of the occasion.
The throttle valve is used to reduce the medium pressure when the pressure drop is extremely large.
