Background technique
The control of the valve on the oil field equipment at present has handwheel control, hydraulic control, pneumatic control, and the valve of hydraulic control is after breaking down aspect the hydraulic control hydraulic pressure, and valve just can't be opened or be closed, and influences oil extraction operation and accident occurs.
The model utility content
Technical problem to be solved in the utility model is that the valve on the existing oil production equipment finishes (for example hydraulic control) by single control mode, when in case described single control mode breaks down, can not open timely or throttle down, influence oil extraction operation and the problem of accident occurs, and provide a kind of hydraulic sluice valve at this problem.
The utility model solves the problems of the technologies described above by the following technical programs:
A kind of hydraulic sluice valve, comprise valve body, be positioned at the flashboard of valve body and comprise oil hydraulic cylinder and the hydraulic pressure installation of piston, described piston is connected with flashboard, it is characterized in that described hydraulic sluice valve also comprises the device that flashboard is moved, this device comprises that the power post and the power post that are used for the power that applies to flashboard move driver part.
Adopt above-mentioned hydraulic sluice valve, when hydraulic pressure installation breaks down, suddenly stop motion, the power post that can open timely in the described device that flashboard is moved moves driver part, the post of exerting all one's strength applies corresponding power to flashboard, help flashboard to continue to finish and open or closing motion, thereby make the staff in time handle the burst accident of valve catastrophic failure, ensure that oil extraction operation carries out smoothly.
In order to solve other technical problem, the utility model has also adopted following technological scheme:
Described power post and flashboard are for dividing body structure;
Described hydraulic sluice valve is provided with two devices that flashboard is moved, and described two devices that flashboard is moved lay respectively on two opposite movement directions of flashboard;
Described power post moves driver part and comprises and the relatively-stationary power column base that comprises tapped through hole at least of valve body that described power column base is connected with the power male screw by tapped through hole.
Description of drawings
Fig. 1 is the structural representation of the described a kind of hydraulic sluice valve of embodiment.
Embodiment
This specification model utility content part has simply been introduced the technological scheme that the utility model adopted, yet, when this technological scheme of practical application, also can produce other technical problem, for this reason, this embodiment is with the detailed related technological scheme of the utility model of introducing.
A kind of hydraulic sluice valve, comprise valve body, be positioned at the flashboard of valve body and comprise oil hydraulic cylinder and the hydraulic pressure installation of piston, described piston is connected with flashboard, and described hydraulic sluice valve also comprises the device that flashboard is moved, and this device comprises that the power post and the power post that are used for the power that applies to flashboard move driver part.
When described power post moves the unexpected stop motion of the piston of driver part in hydraulic pressure installation, can apply corresponding power to flashboard by the power post, making flashboard continue to finish opens or closing motion, it can be the parts that any post of can exerting all one's strength is moved that such power post moves driver part, for example power post one end is connected with piston in the other hydraulic pressure installation, is moved by piston actuated power post; Also power post one end can be connected with piston in the Pneumatic actuator, be moved by piston actuated power post.
And the other end of power post can directly be connected with flashboard, also the piston that can be connected with flashboard (being the piston in the hydraulic pressure installation) connects, such structure makes valve when running, hydraulic pressure installation and described other hydraulic pressure installation or Pneumatic actuator move simultaneously, increased operating cost, still there are the risk that breaks down in the described other hydraulic pressure installation or the Pneumatic actuator that are adopted simultaneously.
As a kind of improvement, power post and flashboard are for dividing body structure, like this, the power post when flashboard applies power with flashboard or the contact of the piston that is connected with flashboard, and under normal conditions, can separate with flashboard or the piston that is connected with flashboard, also be that the motion of power post and flashboard is also asynchronous.
Adopt the branch body structure of epimere text description, make described power post move the mode driving force post that driver part can also adopt hand rotation, this driving mode is manually control, those skilled in the art can be easy to select suitable mechanical structure to move driver part as the power post, for example, when described power post moves driver part employing manual control mode, these parts can comprise and the relatively-stationary power column base that comprises tapped through hole at least of valve body that described power column base is connected with the power male screw by tapped through hole.Fault as hydraulic pressure installation or Pneumatic actuator can not take place in such mechanical structure, has fundamentally eliminated the risk of valve invalidation.
Yet, only adopt the mode driving force post of hand rotation, flashboard is moved along a direction (being the power post applies direction from power to flashboard), and the switch of flashboard needs flashboard to move on two opposite directions, for this reason, the described hydraulic sluice valve of this embodiment is provided with two devices that flashboard is moved, described two devices that flashboard is moved lay respectively on two opposite movement directions of flashboard (directions of opening and closing), described two devices that flashboard is moved were responsible for the opening and closing of flashboard respectively when hydraulic pressure installation lost efficacy.
Embodiment
See Fig. 1, a kind of hydraulic sluice valve, comprise valve body 8, be positioned at valve body 8 flashboard 7, comprise the hydraulic pressure installation of oil hydraulic cylinder 4 and piston 5 and the device that flashboard is moved, valve body 8 is provided with blind flange 6, the interior ring 10 of blind flange 6 is threaded with oil hydraulic cylinder 4 bottoms, and described piston 5 is provided with the link arm 9 that connects piston 5 and flashboard 7 tops.
The described device that flashboard is moved comprises that the power post 2 and the power post that are used for the power that applies to flashboard 7 move driver part, described power post moves driver part and comprises and valve body 8 relatively-stationary power column bases 3, for the present embodiment, power column base 3 is fixed on oil hydraulic cylinder 4 tops that the bottom is threaded with blind flange 6 on the valve body 8 by flange, being provided with tapped through hole in the power column base 3 is threaded with power post 2, power post 2 one ends are connected with handwheel 1, the other end stretches in the oil hydraulic cylinder 4, by rotation hand wheel 1, the technician can adjust the length that power post 2 stretches into oil hydraulic cylinder 4.
When oil hydraulic cylinder 4 runs well, power post 2 does not stretch in the oil hydraulic cylinder 4 (this point can realize by rotation hand wheel 1), and when oil hydraulic cylinder lost efficacy, rotation hand wheel 1, the post 2 of exerting all one's strength stretches into oil hydraulic cylinder 4, and the post 2 of finally exerting all one's strength props up the link arm 9 that is connected by nut with piston 5 with respect to the other end that handwheel 1 connects, and it is mobile simultaneously that the direction of closing to flashboard 7 promotes piston 5, link arm 9 and flashboard 9, and final plant closure flashboard 7.
