Abstract
the utility model discloses a regulating valve with a multi-stack depressurization sleeve, and the regulating valve includes a valve body (1) and a valve core (2), wherein the valve body (1) includes a depressurization sleeve assembly (3) sleeved outside the valve core (2); the depressurization sleeve assembly (3) includes a depressurization sleeve (31) with the multi-stack structure; the depressurization sleeve (31) includes at least one multi-stack unit; and each multi-stack unit includes annual base plates (311) stacked sequentially and at least two annual depressurization plates (311), wherein depressurization through holes (313) are arranged in the annual depressurization plates (311), and the depressurization through holes (313) between each two adjacent depressurization plates (311) are alternately arranged and mutually communicated. The regulating valve has the advantages of excellent depressurization effect, high frictional resistance, efficient avoidance of cavitation erosion and cavitation phenomena, and long service life.
Description
Technical field
The utility model relates to the industrial valves field, is specifically related to a kind of modulating valve with multi-layer stacks step-down sleeve.
Background technique
The sleeve throttleng surface of tradition modulating valve is a rectangular window, and sleeve has only one deck to constitute, in case run into the bigger operating mode of pressure drop ratio; The individual layer sleeve can not carry out effective step-down; Cavitation erosion and cavitation taking place easily, the trim of valve is damaged, has shortened the working life of valve.
The model utility content
The technical problem that the utility model will solve is the problems referred to above to existing technology, provide a kind of antihypertensive effect good, prolong the journey resistance big, can effectively avoid cavitating and the modulating valve with multi-layer stacks step-down sleeve of cavitation phenomenon, long service life.
In order to solve the problems of the technologies described above; The technological scheme that the utility model adopts is: a kind of modulating valve with multi-layer stacks step-down sleeve; Comprise valve body and spool; Said valve body comprises the step-down sleeve assembly that is sheathed on outside the spool, and said step-down sleeve assembly comprises the step-down sleeve with multi-layer stacks structure.
Further improvement as technique scheme:
Said step-down sleeve comprises at least one multi-layer stacks unit; Said multi-layer stacks unit comprises annular bottom plate and at least two annular decompression boards that stack gradually; Said annular decompression board is provided with the step-down through hole, and the step-down through hole interlaced arrangement between the adjacent annular decompression board also is interconnected.
Said step-down through hole is a circular port.
Said step-down sleeve assembly also comprises piece under pressure and last casting die, and said multi-layer stacks unit is clamped and fastened between piece under pressure and the last casting die.
Said piece under pressure is fixed on the valve seat of valve body.
The said casting die of going up is fixed on the middleware of valve body.
The utlity model has following advantage: the utility model step-down sleeve assembly comprises the step-down sleeve with multi-layer stacks structure; The runner of the step-down sleeve of multi-layer stacks structure changes multi-layer stacks into original individual layer circular hole and is formed by stacking; Fluid flows to have increased between multi-layer stacks and prolongs the journey resistance, has consumed the energy of fluid, step by step step-down; Let the pressure of fluid be higher than saturated pressure for vaporization all the time, avoided cavitation erosion and cavitation to take place; Also sub-thread high-energy fluid is dispersed into simultaneously the fluid of the little energy of multiply, step-down is slowed down, and the protection valve body is avoided washing away of high-pressure medium.
