Abstract
The invention discloses a ball valve, and relates to the technical field of ball valve application. At present, multiple ball valves all are controlled by directly pulling a handle; multiple large ball valves are controlled by consuming great effort, and when a handle of a valve is long, the handle occupies larger space. A spiral lead screw rod (1) and a ball valve plug (4) are connected by utilizing a ball spiral lead screw, a valve outer wall (5) fixedly connects two pressure cylinder tubes (3), and two cylinder tube pull rods (6) are connected with lead screw nuts (2). When the cylinder tube pull rods extend or retract and the states change, the two pull rods are connected with the lead screw nuts, so that the lead screw nuts cannot rotate and only can extend or retract along with the pull rods; the lead screw nuts extend or retract to drive the lead screw and the pull rods to rotate, the screw rod rotates and simultaneously drives the ball valve plug to rotate, and the travels of the cylinder tube pull rods are set just to drive the screw rod to rotate for 90 degrees; therefore, the state change of the cylinder tube pull rods just can control the circulation of opening and closing states of a valve in which the ball valve plug (4) is located.
Description
Technical field
The present invention relates to ball valve applied technical field.
Background technique
A lot of ball valve is at present all just have the method directly pulling handle to control.A lot of larger ball valve compares effort when controlling, and takes up room very much when valve handle is longer.
Summary of the invention
The present invention adopts ball screw leading screw, link together by helical screw screw rod (1) with ball valve valve plug (4), valve outer wall (5) is fixedly connected with two pressure cylinder (3), and two cylinder barrel pull bars (6) are connected with feed screw nut (2).
Stretch out when cylinder barrel pull bar or retract, when state changes, two pull bars are connected with feed screw nut, so nut can not rotate, nut can only elongate or shorten with pull bar, and nut elongates or shortens, screw mandrel pull bar is driven to rotate, screw rod rotates and drives ball valve valve plug to rotate simultaneously, and the setting of cylinder barrel rod stroke just in time can drive screw rod 90-degree rotation, thus cylinder barrel pull bar state change just in time can the circulation of control valve plug (4) place valve open-close state.
Installation method and the working procedure of ball screw are, screw mandrel screw rod is fixing up and down can not be moved up and down, can rotate, nut can not rotate, can move up and down during bearing up-down force, nut moves up and down and drives screw rod to rotate, this using method of helical screw has the feature overcoming its using method, by screw rod rotary control valve, has the feature overcoming technology prejudice especially.
Adopt pressure cylinder, the opening and closing of ball screw control valve, can greatly to facilitate, laborsaving control valve, and pressure cylinder is also very easy to be controlled, to reach the object of control valve by automation control systems such as solenoid valves.
Accompanying drawing illustrates:
Fig. 1 is ball-valve structure sketch.
Claims (2)
1. a ball valve, comprise valve outer wall, valve plug (4) its feature also comprise helical screw screw rod (1), nut (2), pressure cylinder, described screw rod and ball valve valve plug (4) link together, valve outer wall (5) is fixedly connected with two pressure cylinder (3), and two cylinder barrel pull bars (6) are connected with feed screw nut (2).
2. the installation method of ball screw and working procedure are, screw mandrel screw rod is fixing up and down can not be moved up and down, can rotate, nut can not rotate, can move up and down during bearing up-down force, nut moves up and down and drives screw rod to rotate, this using method of helical screw has the feature overcoming its using method, by screw rod rotary control valve, has the feature overcoming technology prejudice especially.
