Abstract
The utility model relates to a flow adjustment valve of the high pressure pipeline, comprising a valve body, an upper pressing cover, a valve rod, a sealing base, a lock nut, a fixed base, a sealing ring, a handle, a fixed screw nut and an upper cover. The sealing base is provided with a sealing plug in a cone shape. The upper pressing cover is pressed on the sealing base. The bottom end of the valve rod is provided with two liquid inlets. The valve rod and the fixed base are in thread connection. The high pressure water injection adjustment valve has simple structure, flexible operation, good flow adjustment performance and long service life.
Description
Technical field
The utility model relates to a kind of high pressure pipe line flow control valve.
Background technique
At present, the flow control valve on the high pressure pipe line has gate valve, flashboard easy to wear, stop valve, and it is easy to wear to annotate the plug sealing, and working life is short, because pipeline pressure is big, the valve open and close are dumb.
Summary of the invention
In order to overcome the problem that existing high pressure pipe line flow control valve exists, sealing plug of the present utility model is taper, sealing plug is fixed on the valve rod, after sealing plug is frayed, owing to be that screw thread cooperates, the valve rod rotation is descending, the compensate for wear position with fixed base for valve rod, fixed base adopts the screwed connection sectional area little, and ease off the pressure valve seal plug and sealed valve open and close are flexible.
The technological scheme that its technical problem that solves the utility model adopts is: the high pressure water injection modulating valve is made up of valve body, upper press cover, valve rod, sealing seat, locknut, fixed base, seal ring, sealing plug, handle, set screw nut and loam cake.Sealing plug is arranged on the sealing seat, and sealing plug is taper, and upper press cover is pressed on the sealing seat, and there are two inlet openings the valve rod bottom, and valve rod and fixed base are screwed connection.
The beneficial effects of the utility model are: simple in structure, flexible operation, good, the long service life of Flow-rate adjustment.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is a sectional drawing of the present utility model.
