Description
Technical field
This utility model relates to flow control element technical field, is specifically related to valve technology field, particularly relates to one
Plant throttle.
Background technology
Valve is the control parts in fluid delivery system, has cut-off, regulation, water conservancy diversion, prevents adverse current, voltage stabilizing, shunting
Or the function such as overflow pressure relief.
Choke valve is by changing throttling cross section or chock length to control the valve of fluid flow.By choke valve and unidirectional
Valve parallel connection is then combined into one-way throttle valve.Choke valve and one-way throttle valve are easy flow control valves, at dosing pump hydraulic pressure
In system, choke valve and overflow valve coordinate, and can form three kinds of Metering Flow Control Circuits, i.e. in-line Metering Flow Control Circuits, oil return line
Metering Flow Control Circuits and bypass throttling speed governing system.Choke valve does not has flow negative feedback function, it is impossible to compensates and is changed institute by load
The speed caused is unstable, is typically only used for load and changes little or less demanding to speed stability occasion.
When choke valve in use, some technical problems can be produced.It is thin owing to hydraulic oil existing some abrasive dusts etc.
Little granule, under small guide vane, big differential pressure conditions, the velocity ratio of hydraulic oil is higher, and hydraulic oil forms impulsive force can be to spool and valve
Seat produces serious souring, and the fine particle in hydraulic oil is carry the surface rushing at spool, scrapes one by high speed liquid stream
Rule vestige.Simultaneously the most at high speeds, pressure surge transmission speed in hydraulic oil is fast and decays slow, produce vibration and
Noise.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that throttle.
This utility model is to be achieved through the following technical solutions:
A kind of throttle, including valve body, valve pocket, spool, valve rod, adjusting handle, flange, described valve rod is provided with
Spring base and lower spring cup, and it is arranged with spring on described valve rod；And along its axial line side on the front end face of described spool
To being machined with cylindrical groove, and inwardly it is machined with conical tank in the bottom of described cylindrical groove, at the end of described conical tank
End is provided with noise elimination screw plug；And uniformly it is machined with multiple nail collection slot at the outer surface of described spool.
Further, described valve pocket is arranged on the center position of valve body, and the two sides of valve body offer inlet respectively

Further, one end contact of described spring is in the lower surface of described upper spring seat, and other end contact is under described
The upper surface of spring base.
Further, described spool and described valve pocket are linear sealing, good sealing effect, easily obtain higher regulation pressure,
Reduce the fit tolerance between moving component, it is achieved minor leakage or zero is revealed；And described spool all uses conjunction of the same race with valve pocket
Gold copper-base alloy is made.
Compared with prior art, this utility model has the advantages that and is machined with cylinder in the front end of spool
Groove, its area of passage rate of change is the most constant, is conducive to improving the rigidity of discharge characteristic, and processes in the bottom of cylindrical groove
There is conical tank, noise elimination screw plug is installed in conical tank, it is simple to reduce vibration and noise；By being machined with storage on spool
Bits groove, it is possible to store the fine particle in hydraulic oil liquid, prevents fine particle from producing spool and corrodes, simultaneously when using one section
After between, spool is disassembled, it is simple to the impurity such as the abrasive dust in cleaning nail collection slot.
