Description
Technical field
The invention belongs to throttle valve technology field, is related to a kind of precise throttling valve.
Background technology
The construction of a kind of choke valve generally used now is：Including the valve body with valve pocket, it is formed through on valve body
Its body wall is respectively communicated with oil inlet and oil-out in described valve pocket, and reciprocating valve element, valve element are also equipped with valve pocket
Upper and lower ends be bore and described valve pocket internal diameter identical cock body up and down, formed than valve pocket internal diameter more between the upper and lower cock body
Small adjustment portion, oily Flow-rate adjustment are that by the movement of depression bar to adjust the displacement of adjustment portion to realize.
At present, the movement of adjustment portion is all that armrest is dynamic with feeling to be operated, or speed and displacement are all by fixed electricity
Dynamic operation.The precision of Flow-rate adjustment is not high, can not accomplish precisely to adjust, and regulations speed is too low, can not meet to be actually needed.
The content of the invention
It is an object of the invention to provide a kind of precise throttling valve, solves choke valve present in prior art and is adjusted in flow
The problem of precision is not high when section.
The technical solution adopted in the present invention is a kind of precise throttling valve, including valve body and valve seat, and valve body and valve seat pass through
Screw is fixed together, and the adjusting rod of up/down perforation is vertically arranged with inside valve seat, and the outside of valve seat is exposed on adjusting rod
Scale strip is provided with, the lower end of adjusting rod is connected with valve element, and valve element is arranged in valve body, and the both sides of valve element are respectively arranged with feed liquor
Pipe and drain pipe, feed tube and the drain pipe setting straggly, the place of intersection are provided with restriction, and restriction is located at the valve
The bottom of core.
The features of the present invention also resides in,
The top of adjusting rod is provided with adjusting handle, and the top of adjusting handle and adjusting rod welds together.
The center line of adjusting rod and valve element is on same straight line.
Screw is sunk screw.
Adjusting rod and valve element threaded connection.
The junction of feed tube, drain pipe and valve element is provided with rubber gasket.
The invention has the advantages that a kind of precise throttling valve of the present invention, by being set in the connecting rod of adjusting handle
It scale strip, can accurately be adjusted, be realized than prior art products degree of regulation accuracy, degree of regulation as needed
Stability, the big requirement of flow is applied widely, is not easy affected by environment while of the invention simple in construction, manufacture craft letter
Single, cost is low.
