Abstract
The invention discloses a depressurizing disk sheet for a maze-type adjusting valve. A flow passage (1) on the disk sheet consists of a plurality of groups of grooves which are distributed evenly and symmetrically. The depressurizing disk sheet is characterized in that the grooves are formed by alternatively communicating a plurality of straight flow sections (2) and zigzag sections (3); two ends of each groove are the straight flow sections; and the straight flow sections (1) at two ends of each groove comprise one or two parallel sections. The disk sheet is provided with fixing holes (4). The depressurizing disk sheet for the maze-type adjusting valve has good effects on depressurization and deceleration.
Description
Technical field
The invention belongs to valve technology field, relate in particular to a kind of modulating valve step-down disc.
Background technique
Modulating valve is one of most important element in the hydrodynamic pipeline, and under high pressure, high-velocity fluid effect, existing modulating valve can produce cavitation phenomenon, and trim is caused strong destruction, or produces phenomenons such as noise, vibration.To this, the mazy type modulating valve is by its mazy type dropping equipment, and the pressure and the speed of the reduction fluid that comes alleviating its destruction to trim, thereby are built the working life of valve.The dropping equipment of existing mazy type modulating valve is combined by some mazy type disc stacks, disc has the mazy type groove of distribution symmetrically and evenly as fluid course, this groove is generally some bends and forms, so that fluid consumes the kinetic energy of fluid through each bend the time, reduce its flow velocity, add that liquid clashes into mutually when flowing out runner, realizes the purpose that step-down is slowed down.But which kind of shape no matter the fluid course on the existing disc be, its fluid all is to move in the same direction, though thereby the effect of slowing down through its step-down of a plurality of bends also be limited.
Summary of the invention
The effective depressurizing disk sheet for maze-type adjusting valve that the objective of the invention is to overcome above-mentioned shortcoming and provide a kind of step-down to slow down.
Purpose of the present invention and solve its technical problem underlying and realize by the following technical solutions:
A kind of depressurizing disk sheet for maze-type adjusting valve of the present invention, grooves distributed constitutes the runner on the disc more by organizing symmetrically, and wherein: groove alternately is communicated with by some direct current sections and back-shaped section and forms, and the groove two ends are the direct current section.
The present invention can also adopt following technical measures further to realize.
Above-mentioned depressurizing disk sheet for maze-type adjusting valve, wherein: the direct current Duan Weiyi section at groove two ends or two parallel-segment.
Above-mentioned depressurizing disk sheet for maze-type adjusting valve, wherein: disc is provided with fixed hole.
The present invention compared with prior art, have following tangible advantage and beneficial effect, as can be known from the above technical solutions: the groove that constitutes runner on the disc alternately is communicated with by some direct current sections and back-shaped section and forms, make the fluid at first different direction of runner motion and realize that by bend first kind step-down slows down after entering runner, the kinetic energy that consumes fluid is clashed at the interflow in the same direction mutually when moving then, realizes second class step-down deceleration.After multistage step-down deceleration like this, add that liquid clashes into mutually when flowing out runner, its hydrodynamic pressure and flow velocity all greatly reduce.Thereby its step-down is slowed down effective.The direct current Duan Weiyi section at groove two ends or two groups of parallel-segment constitute, and can be that one-in-and-one-out, advances scene 2, two and advances one to go out, two advances scene 2.
The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.

Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to the depressurizing disk sheet for maze-type adjusting valve that foundation the present invention proposes, its embodiment, structure, feature and effect thereof, describe in detail as after.
Embodiment 1:
Referring to Fig. 1, the one-in-and-one-out depressurizing disk sheet for maze-type adjusting valve, grooves distributed constitutes the runner 1 on the disc more by organizing symmetrically, and wherein: groove alternately is communicated with by some direct current sections 2 and back-shaped section 3 and forms, the groove two ends are the direct current section, and the direct current section 1 at groove two ends is one section.Disc is provided with fixed hole 4.
Embodiment 2:
Referring to Fig. 2, the one-in-and-two-out depressurizing disk sheet for maze-type adjusting valve, grooves distributed constitutes runner 1 on the disc more by organizing symmetrically, wherein: groove alternately is communicated with by some direct current sections 2 and back-shaped section 3 and forms, the groove two ends are the direct current section, and direct current section 1 one ends at groove two ends are that one section, the other end are two parallel-segment.Disc is provided with fixed hole 4.
Embodiment 3:
Referring to Fig. 3, two advance one goes out depressurizing disk sheet for maze-type adjusting valve, grooves distributed constitutes runner 1 on the disc more by organizing symmetrically, wherein: groove alternately is communicated with by some direct current sections 2 and back-shaped section 3 and forms, the groove two ends are the direct current section, and direct current section 1 one ends at groove two ends are that two parallel-segment, the other end are one section.Disc is provided with fixed hole 4.
Embodiment 4:
Referring to Fig. 4, two advance two goes out depressurizing disk sheet for maze-type adjusting valve, grooves distributed constitutes runner 1 on the disc more by organizing symmetrically, wherein: groove alternately is communicated with by some direct current sections 2 and back-shaped section 3 and forms, the groove two ends are the direct current section, and the direct current section 1 at groove two ends is that an end is that two parallel-segment, the other end are two parallel-segment.Disc is provided with fixed hole 4.
During use, referring to Fig. 5, with the stack of multi-disc disc, coupling bar 5 passes the fixed hole 4 on the disc, and all discs are fixed between disc base 6 and the gland 7 as required.When spool 8 moves upward when lifting off a seat, (when actuator drives valve rod spool 8 and moves up and down) fluid enters runner 1 groove, comes the quantity of control panel sheet runner break-make by the height of valve element position, thus the size of control fluid flow (and pressure).
The above, it only is preferred embodiments of the present invention, be not that the present invention is done any pro forma restriction, any technical solution of the present invention content that do not break away from, any modification that technical spirit according to the present invention is done above example, equivalent variations and modification all still belong to the scope of technical solution of the present invention.
