Abstract
A spiral groove type multilevel throttling and pressure reducing disc belongs to the technical field of valves, particularly relates to a throttling and pressure reducing disc used inside an adjusting valve, and comprises an outer sleeve in a bowl shape. A hole is arranged at the bottom of the outer sleeve, a plurality of through holes are arranged on the side wall of the outer sleeve, at least two inner sleeves are arranged inside the outer sleeve, a spiral groove is arranged on the side wall of each inner sleeve, and a plurality of through holes are arranged in each spiral groove. The spiral groove type multilevel throttling and pressure reducing disc has the advantages of fine throttling effect and long service life.
Description
Technical field
The utility model belongs to the valve technology field, is specifically related to the expenditure and pressure dish of the inner usefulness of a kind of modulating valve.
Background technique
The expenditure and pressure dish is to be used for the equipment that valve inside is used to regulate flow, and existing valve inside is not established the throttling dish or expenditure and pressure dish simple in structure is set, and restriction effect is not obvious, and the life-span of valve device is short.
Summary of the invention
The purpose of this utility model is: provide that a kind of pressure relief ranges is wide, can regulate, good linearity, long expenditure and pressure dish of life-span.
The purpose of this utility model is achieved in that a kind of spiral groove type multistage throttle decompression dish, the bowl-shape outside cover that comprises a bottom opening, the sidewall of described outside cover is offered some through holes, at least two inboard covers of the inner setting of described outside cover, the sidewall of described each inboard cover is provided with spiral chute, and some through holes are set in the described spiral chute.
When the utility model passes through pressurized gas, owing to have a plurality of inboard covers, can realize the process of compression-expansion-recompression-expansion-recompression, compressing and expanding all can reduce hydrodynamic pressure each time, eliminates hydraulic potential.Final hydrodynamic pressure is descended greatly, realize the step-down discharging; Fluid enters lumen by the outside during work, and every layer of cover all constitutes throttleng surface, makes hydrodynamic pressure reduce gradually, can alleviate the High Pressure Difference fluid so greatly to the washing away of downstream unit, and protects equipment effectively, realizes exempting to wash away, and prolongs the working life of equipment.
In sum, the utlity model has good throttle effect, long beneficial effect of life-span.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the structural representation of an inboard cover of model utility.
Embodiment
As shown in Figure 1, 2, a kind of spiral groove type multistage throttle decompression dish comprises that the bowl-shape outside of a bottom opening overlaps 4, the sidewall of outside cover 4 is offered some through holes, cover 4 inside, the outside are provided with three inboard covers 1,2,3, and the sidewall of each inboard cover is provided with spiral chute 5, and some through holes are set in the spiral chute 5.
