Abstract
A big valve switch tool belongs to the technical field of oil field ground engineering. One end of the steel pipe is provided with a long claw and a short claw, the lower end of the long claw is provided with a through hole, and the through hole is connected with a switch handle; a groove is arranged between the long claw and the short claw. The utility model has the advantages that convenient, swift, the security is reliable, can not receive the valve sleeve instrument of space restriction, make operating personnel can many people carry out the switch valve operation subaerial. The potential safety hazard caused by the fact that an operator needs to stand on the semi-air pipeline to operate is eliminated, and human body injury caused by sliding off the high-altitude pipeline is avoided. The use of the tool improves the safety operability, greatly reduces the labor intensity and improves the working efficiency.
Description
Technical field
The utility model relates to a kind of large valve switch instrument, belongs to oilfield surface engineering technical field.Background technique
At present in each oil field system place, there is the process pipelines varying in size that control valve is installed on the ground, some valves (being mainly DN250mm-DN500mm) are larger, the handwheel of setting height(from bottom) from ground to valve has the height of 1.5-1.9 rice, can only two people during operation stand in and aspectantly on the pipeline being in midair connected with valve carry out valve switch operation, the large valve of DN250mm-DN500mm, in long-term use, exist corrosion, fouling, valve handle switch is heavy, sometimes need many people's operations, restriction due to operating position, many people can not operate simultaneously, flow process is long switching time, have influence on burst accident is processed in time.Operation, has ice and snow on pipeline in the winter time, and operator are easy to landing from pipeline and get off, and to personal safety, bring hidden danger.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of large valve switch instrument.
A large valve switch instrument, there are long pawl and short pawl in one end of steel pipe, and there is through hole the lower end of long pawl, through hole connecting valve handle; Between long pawl and short pawl, there is groove.
The utility model has the advantages that convenient, fast, Security is reliable, space-constrained valve sleeve barrel tool, does not make operator on the ground and can many people carry out switch valve operation.Eliminate operator and need to stand in the potential safety hazard that the enterprising line operate of pipeline brings in midair, avoid landing from the pipeline of high-altitude to cause human injury.The use of this instrument has improved safe operability, greatly reduces labor intensity, and working efficiency can be improved.
The large valve unit of DN250mm-DN500mm that is suitable for installing is on the ground used, and has certain promotional value.
Accompanying drawing explanation
When considered in conjunction with the accompanying drawings, by the detailed description with reference to below, can more completely understand better the utility model and easily learn wherein many advantages of following, but accompanying drawing described herein is used to provide further understanding of the present utility model, form a part of the present utility model, schematic description and description of the present utility model is used for explaining the utility model, do not form improper restriction of the present utility model, as schemed wherein:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is cross section structure schematic diagram of the present utility model.
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment
Obviously, the many modifications and variations that those skilled in the art do based on aim of the present utility model belong to protection domain of the present utility model.
Embodiment 1: as shown in Figure 1 and Figure 2, a kind of large valve switch instrument, according to handwheel lacing wire quantity different (having five lacing wires and six handwheel lacing wires), selects suitable caliber as handwheel sleeve, makes the valve handle sleeve barrel tool of different size.
The present embodiment uses the valve of DN350mm as the explanation of instrument.
A large valve switch instrument, there are long pawl 4 and short pawl 2 in one end of steel pipe 1, and there is through hole 5 lower end of long pawl 4, through hole 5 connecting valve handles; Between long pawl 4 and short pawl 2, there is groove 3.
Measure height and the valve handle internal diameter of the following convenient operation of handwheel.
According to the internal diameter size of handwheel, be ∮ 470mm, select the steel pipe 1 of ∮ 426mm, the length of intercepting convenient operation is as sleeve barrel tool, according to the width of the internal diameter of handwheel and lacing wire angle arc width and handwheel lacing wire, on steel pipe, cut out 3 corresponding long pawls 4, the through hole 5 of opening a diameter 25mm in the lower end of 3 long pawls level is used for wearing steel pipe as switch knob.
During operation, by the handle on socket bar, rotate handwheel, thereby carry out the switching manipulation of valve, thereby easy-to-operat personnel operate on ground.
As mentioned above, embodiment of the present utility model is explained, but as long as not departing from fact inventive point of the present utility model and effect can have a lot of distortion, this will be readily apparent to persons skilled in the art.Therefore, within such variation is also all included in protection domain of the present utility model.
