Description
Technical field
A kind of choke valve of present invention design, specific design is a kind of steady, and noise is small, and flow is accurately controlled, and erosion resistance is resistance to
Abrasion, the cage type throttling valve of long service life.
Background technology
It is main in the choke valve that uses at present to have needle valve choke valve, disc type choke valve, a cage type throttling valve, and cage shell type
Choke valve restriction effect is preferable, but cage type throttling valve has the following disadvantages at present：(1) with solids such as the grains of sand in fluid
Grain, the fluid high-speed of mixing directly washes away cage set hole and valve seat, and this can cause cage to cover hole and valve seat rapid deterioration, quick abrasion, longevity
Life is short.(2) cage set and valve rod are that gap be connected or cage set and valve rod are one overall, cause flow control inaccurately, when throttling not
Steady and noise is big.(3) in valve closing, cage covers and valve element directly contact, causes to clash, and causes cage to cover and damages.Cause
The wearability abrasion-resistance of this enhancing cage type throttling valve valve seat and cage set be improve cage type throttling valve service life must be by
Approach.
Therefore, it is necessary that a kind of reasonable in design of research and development is designed on the basis of prior art, operate steadily, make an uproar
Sound is small, and flow is accurately controlled, good seal performance, and erosion resistance is wear-resistant, the cage type throttling valve of long service life.
The content of the invention
Goal of the invention：The invention aims to provide a kind of reasonable in design, operate steadily, noise is small, flow
Accurately control, good seal performance, erosion resistance is wear-resistant, the cage type throttling valve of long service life.
Technical scheme：In order to realize the purpose of the present invention, the technical solution adopted by the present invention is：
A kind of cage type throttling valve, it include valve body, the valve seat in valve body, the spring in valve seat orifice,

Upper inner hole sleeve valve rod it is cylindrical on；Bonnet is arranged on valve body by bolt, and described bonnet is connected with threaded stem；Tubular
Filter holder is fixedly connected with bonnet lower end, and translucent cover is connected with bonnet upper end, and valve rod upper end is connected with handwheel, valve rod lower end with
Cage set connection, the cage set balance pipe that cage puts is communicated with the valve rod balance pipe on valve rod, and hard is provided with described cage set hole
Alloy bushing；
Described cartridge filtration support includes tubular frame, upper ring washer, lower ring washer and copper cash, described upper ring washer and lower ring washer
It is separately mounted on tubular frame, copper cash is arranged in order the outside for being wound on tubular frame, offers tubular frame radially on tubular frame is cylindrical
Hole and tubular frame cannelure；
Described valve seat it is cylindrical on three row throttle orifices are offered near longitudinal center line.
Preferably, above-described a kind of cage type throttling valve, described bonnet lower end and valve rod junction, from
Pad, metallic packing ring and back-up ring are up to sequentially provided with down.
Preferably, a kind of above-described cage type throttling valve, described valve rod top is provided with instruction nut,
Indicative function can be played to cage set position.
Preferably, above-described a kind of cage type throttling valve, the outer surface of described translucent cover is provided with finger
Indicating board.
Preferably, a kind of above-described cage type throttling valve, is provided with for standing valve on described bonnet
The holding screw of bar position, can firm discharge after holding screw fixes stem position.
Preferably, a kind of above-described cage type throttling valve, described often row throttle orifice has four to wait merogenesis
Discharge orifice, throttle orifice is interlaced between row and row, and throttle orifice is overlapped and progressively reduced from top to bottom.
A kind of cage type throttling valve specific work process for providing of the invention and principle are：
Fluid enters from the right entry of valve body, through entering tubular frame cannelure in the gap of copper cash, then through tubular frame radially
Hole enters in tubular frame, so using the gap filtering fluid between copper cash, can reduce the abrasion of cage set hole and valve seat, reduces fluid
Erosion to cage set and valve seat, improves cage type throttling valve service life.And the spring in valve seat makes cage cover all the time pressure upwards
Tightly on valve rod, in valve closing, cage set and valve seat will not clash into, and steady during throttling, noise is small.
During throttling, handwheel is rotated clockwise, band ovable valve stem and cage set decline, and the area of valve seat throttle orifice is gradually reduced, and flows
Amount is gradually reduced, until cage set closes throttle orifice.Handwheel is rotated counterclockwise, band ovable valve stem and cage set rise, the area of throttle orifice
Gradually increase, flow gradually increases, until throttle orifice all exposes maximum flow.When handwheel is rotated, by observing Pointing sign board
On scale when reaching the flow of regulation, lock holding screw, can firm discharge, reach flow control accurate.
Beneficial effect：Compared to the prior art a kind of cage type throttling valve that the present invention is provided has advantages below：
The cage type throttling valve that the present invention is provided, reasonable in design operates steadily, and noise is small, and flow is accurately controlled,
Good seal performance, erosion resistance is wear-resistant, long service life.
The choke valve filters fluid by gap between tubular frame and copper cash, be capable of achieving cage set hole and valve seat erosion resistance,
It is wear-resistant, improve choke valve service life.Spring in valve seat makes cage set be pressed on valve rod upwards all the time, in valve closing
When, cage set and valve seat will not clash into, and steady during throttling, noise is small and flow control is accurate.The ordered arrangement of throttle orifice on valve seat,
Realize the reduction of flow continuous and stable during throttling.
