Face is equipped with the concentric lower annulus wall of several circles, and upper annulus wall and lower annulus wall are interlaced, upper annulus wall and lower annulus wall it
Between form accumulation of energy annular groove, several decompression throttle orifices are offered on annulus wall and lower annulus wall on every circle, and adjacent
The position of upper annulus wall and the decompression throttle orifice of lower annulus wall mutually staggers.
The decompression throttle orifice of the upper annulus wall from the decompression throttle orifice of the upper annulus wall of innermost circle to outmost turns
It gradually becomes smaller, the decompression throttle orifice of the lower annulus wall from the decompression throttle orifice of the lower annulus wall of innermost circle to outmost turns
It gradually becomes smaller.
The mutual radially aligned of decompression throttle orifice of every circle upper annulus wall, the decompression throttle orifice of every circle lower annulus wall
Mutual radially aligned.
The upper surface of the lower disc is equipped with locating piece, and location hole is provided on locating piece, and the lower surface of upper disc is corresponding
Locating piece offers positioning recess, and location hole is corresponded in positioning recess equipped with positioning pin.
Compared with prior art, the invention has the following advantages:
1 present invention is main by the way of " water storage " buffering, designs accumulation of energy annular groove after every grade of decompression throttle orifice and slows down
Flow rate of liquid improves the static pressure of the liquid in accumulation of energy annular groove, slows down liquid to the lasting high speed impact of decompression disc.In liquid
After entering accumulation of energy annular groove by decompression throttle orifice, the effect of the liquid retained in the effect and accumulation of energy annular groove due to accumulation of energy,
Under the liquid medium buffer function that retains in accumulation of energy annular groove of high-speed liquid medium that outside flows into, flow velocity is by fast prompt drop
Low, for the liquid medium retained in accumulation of energy annular groove when being impacted by high-speed liquid, the liquid that retains is by the impact of high-speed liquid
Energy absorption, and the impact energy of high-speed liquid is reduced, the impact being transferred on annulus wall and pressure reducing disc also will be just reduced in this way
Power, the impact energy for receiving pressure relief assembly are substantially reduced, and are reduced high-speed liquid and are washed away to the destruction inside pressure reducing disc, to prolong
Its long service life.
2, the pressure reducing disc of pressure relief assembly of the invention after assembling due to can guarantee using being fastened up and down to dress mode
Enough reduction of speed annular channels, the decompression throttle orifice of punching press can use uneven distribution mode on each annulus wall, as long as guaranteeing
Enough decompression areas at different levels.
3, the present invention solves the cavitation damage of regulating valve, every in multi-step pressure reduction mainly by the way of multi-step pressure reduction
Level-one all consumes part energy, so that the inlet pressure of next stage is relatively low, reduces the pressure difference of next stage, pressure recovery drop
It is low, the intensity of cavitation is reduced, and design accumulation of energy annular groove in every level-one relief outlet, accumulation of energy annular groove can make flow rate of liquid quick
It reduces, forms opposite static pressure field, slow down the direct impact between each pressure reduction stage, can effectively improve the antifatigue of pressure relief assembly
Ability.
4, the processing and forming of lower-cost accurate heat stamping and shaping can be used in the present invention, changes original electricity
Burn into electric carving carves contour cost processing technology, greatly reduces the production cost of regulating valve.And it is of the invention easy for assembly, significantly
Reduce the manufacturing cost of regulating valve.

Specific embodiment
The present invention is further described below with reference to embodiment.
The multistage accumulation of energy buck configuration regulating valve of the present embodiment includes valve body, valve seat, spool, valve deck and pressure relief assembly, is subtracted
Pressing component includes pressure reducing disc, and the through hole 5 passed through for spool is provided in the middle part of pressure reducing disc.The pressure reducing disc that pressure relief assembly includes
Quantity can be one, be also possible to multiple, and when there is multiple pressure reducing discs, multiple pressure reducing discs are corresponding in turn to overlapping by thickness direction
Together, the through hole among each pressure reducing disc is mutually aligned.As shown in figures 1-4, pressure reducing disc includes the upper of upper and lower corresponding fastening
Disc 2 and lower disc 1, the lower surface of upper disc 2 are equipped with the concentric upper annulus wall 21 of several circles, and the upper surface of lower disc 1 is equipped with
The concentric lower annulus wall 11 of several circles, upper annulus wall 21 and lower annulus wall 11 are interlaced, in upper annulus wall 21 and lower annulus wall
Accumulation of energy annular groove 4 is formed between 11.The present embodiment is provided with five and encloses upper annulus wall 21 and the lower annulus wall 11 of five circles, certainly, upper circle
The quantity of ring wall 21 and lower annulus wall 11 can be according to actual use Demand Design.Annulus wall 21 and lower annulus wall 11 on every circle
On offer several decompression throttle orifices 3, and the position of the decompression throttle orifice 3 on adjacent upper annulus wall 21 and lower annulus wall 11
Set and mutually stagger, i.e., not it is same radially.16 are offered on annulus wall and lower annulus wall on every circle of the present embodiment
