Abstract
The utility model belongs to the technical field of oil production equipment, and relates to a moving control device for a disc of a gate valve, aiming to solve the problems in the conventional control technology in controlling the disc of the gate valve that a ball screw is adopted to replace a traditional screw rod for reducing twisting moment, however, balls in the ball screw are contacted with one another, resulting in collision among the balls and large noise when the ball screw rotates; and the resisting force for rotating the ball screw is not reduced considerably to meet the demands of gate open/close. The utility model provides a moving control device for a disc of a gate valve, which comprises a ball screw connected with a disc and a screw rod seat at least comprising a screw rod seat main body; the screw rod seat further comprises a ball keeper arranged on the screw rod seat main body; the ball keeper comprises isolating cushions isolating adjacent balls; and sunken parts matched with adjacent balls are arranged on each isolating cushion. The mentioned technical problems can be effectively solved by adopting the technical scheme.
Description
Technical field
The utility model belongs to the oil exploration equipment technical field, relates to a kind of control device, is specifically related to a kind of gate valve flashboard mobile controller.
Background technology
Valve control on the oil field equipment at present has handwheel control, hydraulic control, pneumatic control, manually control is because the fluid pressure height of being controlled, resistance was big when danger caused valve opening greatly, valve can't be opened, though the valve of the gentle pressure-controlled of hydraulic control is arranged, but manually control is generally still adopted in the place in remote and condition difference, for solving big this problem of high pressure valve opening moment, prior art has substituted traditional screw mandrel with ball screw, yet the ball in the ball screw contacts, when the swing roller screw mandrel, can produce the collision between ball and the ball, send a large amount of noises, the resistance of swing roller screw mandrel is not significantly reduced to satisfy the purpose of controlled valve simultaneously.
The utility model content
Technical problem to be solved in the utility model is that the control technology of existing control gate valve flashboard adopts ball screw to replace traditional screw mandrel, to reduce rotating torque, yet the ball in this ball screw contacts, when the swing roller screw mandrel, can produce the collision between ball and the ball, send a large amount of noises, the resistance of swing roller screw mandrel is not significantly reduced the problem with the purpose that satisfies controlled valve simultaneously, and provides a kind of gate valve flashboard mobile controller at this problem.
The utility model solves the problems of the technologies described above by the following technical programs:
A kind of gate valve flashboard mobile controller, comprise ball screw that is connected with flashboard and the screw rodb base that comprises the screw rodb base body at least, it is characterized in that described screw rodb base also comprises the ball retainer that is arranged on the screw rodb base body, described ball retainer comprises the isolating pad of isolating adjacent ball, and isolating pad is provided with the depressed part that is complementary with adjacent ball.
In order to satisfy field produces, safety, demand efficiently, the utility model can make adjacent ball not contact by discovering the buffer action by the isolating pad in the ball retainer, thereby can not take place because of the metallic sound that conflicts and produce between ball and the ball, and ball disappears because of the isolation between ball and the ball with mutual friction mutually between the ball, the wearing and tearing of ball also disappear certainly, simultaneously, isolating pad is arranged ball equably and is carried out circulating rolling, makes motion become level and smooth stable.
Friction as for ball and isolating pad depressed part fully can be by adding lubricating grease at the isolating pad depressed part and reducing as much as possible, and thus, a kind of gate valve flashboard mobile controller described in the utility model need not maintenance for a long time.
The utility model is also further found, generally speaking, the relative friction velocity of the ball in the utility model only is about 1/2 of ball in the existing ball screw, face is pressed step-down, heating reduces, the rolling friction change more only is about 1/10 of traditional sliding screw, compares with traditional sliding screw, and the driving torque maximum of a kind of gate valve flashboard mobile controller described in the utility model only is 1/3rd of traditional sliding screw.
In order to solve other technical problem, the utility model has also adopted following technical scheme:
Described ball is connected with the screw rodb base body by the depressed part on the isolating pad.
Description of drawings
Fig. 1 is the structural representation of the described a kind of gate valve of embodiment;
Fig. 2 is the structure for amplifying schematic diagram of the flashboard mobile controller in the described a kind of gate valve of embodiment.
The specific embodiment
Embodiment
See Fig. 1, a kind of gate valve, the valve body control device that comprises valve body 6 (being provided with flashboard in it) and application valve body 6 switches, described valve body control device bottom is provided with first adpting flange 8, valve body 6 tops are provided with second adpting flange 7, and valve body 6 is connected with second adpting flange 7 by first adpting flange 8 with the valve body control device.
The body 9 that the valve body control device comprises gate valve flashboard mobile controller and entangles gate valve flashboard mobile controller.
See Fig. 2, described gate valve flashboard mobile controller comprises the ball screw 4 that is connected with flashboard, the screw rodb base that comprises screw rodb base body 2 and handwheel 5, the body 9 rotary screw rod seat bodies 2 of described handwheel 5 by being connected with screw rodb base body 2 thimbles.
Described screw rodb base also comprises the ball retainer that is arranged on the screw rodb base body 2, and described ball retainer comprises the isolating pad 3 of isolating adjacent ball 1, and isolating pad 3 is provided with the depressed part 10 that is complementary with adjacent ball 1.
Claims (2)
1. gate valve flashboard mobile controller, comprise ball screw that is connected with flashboard and the screw rodb base that comprises the screw rodb base body at least, it is characterized in that described screw rodb base also comprises the ball retainer that is arranged on the screw rodb base body, described ball retainer comprises the isolating pad of isolating adjacent ball, and isolating pad is provided with the depressed part that is complementary with adjacent ball.
