Description
Technical field
The utility model relates to a kind of frictional force that valve rod and nut are reduced using ball to reduce valve switch torque
Ball screw gate valve.
Background technique
In case of high pressures, the opening and closing of valve are all very laborious for oil field shaft mouth gate valve, when worker operation normally all
It is to increase the opening and closing arm of force using extension bar come smaller torque.
Summary of the invention
The purpose of this utility model is the situation laborious for the switch for operating valve under high-pressure state, and providing one kind makes
The frictional force of valve rod and nut is reduced with ball to reduce the ball screw gate valve of valve switch torque.
The purpose of this utility model solves by the following technical programs：
A kind of ball screw gate valve, including valve body, valve deck, it is characterised in that：Ball-screw is equipped on the upside of the valve deck
Assembly, the lower part of the nut set in ball-screw assembly is in box cupling and box cupling is fixed at the upper end of valve deck, nut
The upper end of set is connected by bolt with the connector with inner cavity, handwheel is fixed on connector, the ball wire as valve rod
Ball screw in thick stick assembly driving ball screw can rise or fall in handwheel band follower link and nut set rotation.
The inner cavity internal diameter of the connector is greater than the outer diameter of ball screw.
The lower part of the nut set is equipped with a circular step column, and circular step column is embedded in the top of valve deck by bearing
Between the inner cavity roof of box cupling.
Be equipped with ball sleeve in the described nut set, ball screw be arranged in ball sleeve and can under the action of handwheel edge
The axial direction of ball sleeve rise or fall.
The lower end of the ball screw is protruded into valve chamber and is connected with the valve plate in valve seat.
The utility model has the following advantages compared with prior art：
As effort-saving mechanism, valve rod and nut are reduced using ball by using ball-screw assembly for the utility model
Frictional force, to reduce valve switch torque；The gate valve structure is compact, easy for installation and use is safe, easy to operate, greatly mitigates
The labor intensity of worker, effectively save production cost improve production efficiency and increase economic benefit.

Specific embodiment
The utility model is further described with embodiment with reference to the accompanying drawing.
As shown in Figs. 1-2：A kind of ball screw gate valve, including valve body 1, valve deck 2 are equipped with ball-screw on the upside of valve deck 2
Assembly 3, nut set 4 in ball-screw assembly 3 lower part is in box cupling 5 and box cupling 5 is fixed at the upper of valve deck 2
The upper end at end, nut set 4 is connected by bolt with the connector 6 with inner cavity, handwheel 7 is fixed on connector 6, as valve
Ball screw 8 in the ball-screw assembly 3 of bar can drive ball wire when handwheel 7 is with follower link 6 and nut 4 rotation of set
Bar 8 rises or falls, and the lower end of ball screw 8 is protruded into valve chamber 12 and is connected with the valve plate 14 in valve seat 13.?
In above-mentioned gate valve, it is equipped with a circular step column 9 in the lower part of nut set 4, and circular step column 9 is embedded in valve deck by bearing 10
Between 2 top and the inner cavity roof of box cupling 5；Ball sleeve 11 is equipped in nut set 4, ball screw 8 is arranged in ball sleeve 11
It is interior and can be risen or fallen under the action of handwheel 7 along the axial direction of ball sleeve 11.It should be noted that the inner cavity of connector 6
Internal diameter is greater than the outer diameter of ball screw 8, in order to the lifting on 8 top of ball screw.
As shown in Figs. 1-2, rotation hand wheel 7 make the nut in ball-screw assembly 3 cover 4 rotations, to drive ball sleeve 11
Rotation forces ball screw 8 to move up or down, so that the valve plate being connected on ball screw 8 14 is moved up and down,
Valve is formed to open and close.
The utility model is used as effort-saving mechanism by using ball-screw assembly 3, reduces valve rod and nut using ball
Frictional force, to reduce valve switch torque；The gate valve structure is compact, easy for installation and use is safe, easy to operate, greatly subtracts
The light labor intensity of worker, effectively save production cost improve production efficiency and increase economic benefit.
Above embodiments are only to illustrate the technical idea of the utility model, and the protection model of the utility model cannot be limited with this
Enclose, it is all according to the utility model proposes technical idea, any changes made on the basis of the technical scheme each falls within this reality
Within the scope of novel protected；The technology that the utility model is not directed to can be realized by the prior art.
