Description
Technical field
The utility model designs a kind of throttle valve, and specific design is steadily a kind of, and noise is little, and flow can accurately control, and erosion resistance is wear-resistant, the cage type throttling valve of long service life.
Background technique
Needle valve throttle valve, disc type throttle valve, cage type throttling valve is mainly contained in the throttle valve of current use, and cage type throttling valve restriction effect is better, but there is following shortcoming in cage type throttling valve at present: with solid particles such as the grains of sand in (1) fluid, the fluid high-speed of mixing directly washes away cage trepanning and valve seat, this can cause cage trepanning and valve seat rapid deterioration, quick abrasion, the life-span is short.(2) cage cover and valve rod are that recessed bond ing or cage overlap with valve rod is one overall, steady and noise is large when causing flow control inaccuracy, throttling.(3) when valve closing, cage cover directly contacts with spool, causes clashing, and causes cage to overlap and damages.Therefore strengthen wear resistance abrasion-resistance that cage type throttling valve valve seat and cage overlap be improve cage type throttling valve working life must by approach.
Therefore, necessary design on the basis of prior art researches and develops a kind of reasonable in design, and operate steadily, noise is little, and flow can accurately control, good seal performance, and erosion resistance is wear-resistant, the cage type throttling valve of long service life.

A kind of cage type throttling valve specific works process that the utility model provides and principle are:
Fluid enters from the right entry of valve body, tubular frame cannelure is entered in the gap of copper cash, enter in tubular frame through tubular frame radial hole again, the gap between copper cash is utilized to filter fluid like this, the wearing and tearing of cage trepanning and valve seat can be reduced, reduce fluid to cage cover and the erosion of valve seat, improve cage type throttling valve working life.And the spring in valve seat makes cage overlap upwards to be pressed on valve rod all the time, when valve closing, cage cover and valve seat can not clash into, steady during throttling, noise is little.
During throttling, rotate clockwise handwheel, band ovable valve stem and cage cover decline, and the area of valve seat throttle orifice reduces gradually, and flow reduces gradually, until throttle orifice closed by cage cover.Rotate counterclockwise handwheel, band ovable valve stem and cage cover rise, and the area of throttle orifice increases gradually, and flow increases gradually, until throttle orifice all to expose flow maximum.When rotation handwheel, when reaching the flow of regulation by the scale observed on Pointing sign board, locking Cock screw, can firm discharge, reaches flow control accurate.
Beneficial effect: compared to the prior art a kind of cage type throttling valve that the utility model provides has the following advantages:
The cage type throttling valve that the utility model provides, reasonable in design, operates steadily, and noise is little, and flow can accurately control, good seal performance, and erosion resistance is wear-resistant, long service life.
This throttle valve filters fluid by gap between tubular frame and copper cash, can realize the erosion resistance of cage trepanning and valve seat, wear-resistant, raising throttle valve working life.Spring in valve seat makes cage overlap upwards to be pressed on all the time on valve rod, and when valve closing, cage cover and valve seat can not clash into, steady during throttling, noise is little and flow control is accurate.The ordered arrangement of throttle orifice on valve seat, the reduction of flow continuous and stable when realizing throttling.
