Abstract
The utility model discloses a multi-orifice decompression flow regulating valve. A valve bush is arranged in a valve body, and is positioned between an inlet and an outlet; the upper end of the valve bush is connected with a valve cap; the lower end of the valve bush is provided with a sealing socket and is in sealed connected with the outlet; the lower part of the valve bush is provided with orifices communicated with the outlet; and a valve rod and the valve bush are perpendicularly arranged on the valve body. The utility model has the advantages that the multi-orifice decompression flow regulating valve has high differential pressure and good cavitation resistance and regulates the flow accurately and reliably, the flow in the whole process is controllable and linear, the driving force of the valve rod is not influenced by the pressure in the valve, and a guider and the orifices are connected to form the valve bush, so that the valve is easy and convenient to mount and maintain; and the valve bush is perpendicularly arranged, so the valve bush can be hoisted vertically and a sealing element can be changed on line. The multi-orifice decompression flow regulating valve comprises main parts such as the valve body, the valve cap, the valve bush, the sliding bush gate and the sealing socket, and does not comprise easily-worn parts except the sealing element, so the multi-orifice decompression flow regulating valve has long service life, and the sealing element can be replaced by opening the valve cap and taking the sliding sleeve gate out.
Description
Technical field
The utility model relates to the technical field of valve, a kind of specifically many spray orifice decompression flow-adjustable valve, particularly its mechanical connecting structure.
Background technique
At present, most flow-adjustable valves use General valve to substitute, and like butterfly valve, gate valve, ball valve etc., their total shortcoming is: 1, not omnidistance controlled, and uncontrollable basically under small flow.2, be easy to generate cavitation erosion under the higher operating mode of pressure reduction.3, there is not dissipating functions.4, the current-regulating voltage-regulating precision is low.5, generally can not on-line maintenance.
Summary of the invention
The purpose of the utility model is to provide a kind of many spray orifices decompression flow-adjustable valve, thereby reaches omnidistance controlled current-regulating voltage-regulating, can long-term work under High Pressure Difference and not cavitation erosion, and the current-regulating voltage-regulating validity is high, has dissipating functions, but the purpose of on-line maintenance.
To achieve these goals, the technological scheme of the utility model is: a kind of many spray orifice decompression flow-adjustable valves, and it comprises valve body, valve body is imported and exported coaxial; Valve body one side is provided with entrance point, and the valve body opposite side is provided with outlet end, it is characterized in that: said valve body upper end is provided with valve gap, and the valve gap place is provided with sealing axle sleeve; Valve rod and sealing axle sleeve sealed sliding are dynamically connected, and valve rod runs through valve gap, and an end of valve rod places valve gap outside; Stem lower portion and sliding sleeve lock top are affixed, and sliding sleeve lock place is provided with pressure compensation opening, is provided with valve pocket in the valve body; Valve pocket between entrance point and outlet end and with import and export axis normal, the valve pocket upper end is connected with valve gap, the valve pocket lower end be equipped with sealing seat also and outlet end be tightly connected; The valve pocket bottom is provided with spray orifice, and spray orifice is communicated with outlet end, and said valve rod and valve pocket are vertically installed in the valve body place.
The utility model discloses a kind of many spray orifice decompression flow-adjustable valves, its advantage is that pressure reduction is big, and anti-cavitation erosion is effective; Regulate accurately reliable; Omnidistance flow is controlled and be linear, and the driving force of valve rod does not receive the influence of valve internal pressure, and guiding makes installation and maintenance simple and convenient with spray orifice disjunctor formation valve pocket; Because valve pocket is vertically arranged, but can straight up and down lift and the on-line replacing Sealing.The critical piece of these many spray orifice decompression flow-adjustable valves has only valve body, valve gap, valve pocket, sliding sleeve lock and sealing seat, except Sealing, does not have quick-wear part, so the life-span of valve is long, only needs when changing Sealing valve gap is opened, and taking out the sliding sleeve lock is replaceable Sealing.Handwheel, hydraulic pressure or cylinder or electrical header in the configuration can become manually, surge or electronic decompression flow-adjustable valve.
