When work, regulating valve is closed, and the water or oil of cylinder interior cannot flow out, then flap 5 is immovable, is in valve body 1
Intermediate position, at this time valve wide open, flow resistance very little；
4. when booster occurs, velocity of medium is more than Zm/s, and the active force that flow velocity generates at this time is set more than elastomeric element 26
The small valve core 25 of fixed power, regulating valve is opened, and the water or oil of cylinder interior are extruded under 5 thrust of flap, then flap 5 is opened
Begin to move, executes and close valve events, close the speed of valve by the adjusting of needle-valve 19, the closing of two benches speed may be implemented, avoid
Occur closing valve water hammer.
In conclusion the above is only the preferred embodiments of the present utility model only, the utility model should not be limited with this
Range.It is i.e. every according to simple equivalent changes and modifications made by the utility model claims book and description, all answer
Still belong in the range of the utility model patent covers.
