Abstract
The utility model relates to the technical field of cutting silk and discloses double-buckle cutting silk. The double-buckle cutting silk comprises a body, one end of the body is provided with a metric male buckle thread, and the other end of the body is provided with an inch male buckle thread. The double-buckle cutting silk has reasonable and compact structure. One end of the double-buckle cutting silk is the inch male buckle thread, and the other end is the metric male buckle thread, so the inch male buckle thread and the metric male buckle thread can be converted according to the actual situation, and the cutting silk does not need to be replaced. Thus, the working capacity is reduced, and the engineering time and cost is saved.
Description
Technical field
The utility model relates to the studding technical field, is a kind of dimorphism button studding.
Background technology
In under balance pressure drilling wellhead equipment installation process, be used to connect the studding of rotating blowout preventer and annular preventer, its two ends screw thread is general complete to be English system or metric system.When the screw thread of annular preventer top screwed hole is made in Great Britain, when being metric system, the screw thread at studding two ends just can't connect; Or when the screw thread of annular preventer top screwed hole be metric system, and the screw thread at studding two ends also can't connect when made in Great Britain, needs the on-the-spot studding of changing usually when running into above two kinds of situations, has not only increased workload, has also wasted engineering time and cost.
Summary of the invention
The utility model provides a kind of dimorphism button studding, has overcome the deficiency of above-mentioned prior art, and it can effectively solve the problem that studding has increased workload, wasted time and cost of changing.
The technical solution of the utility model realizes by following measure: a kind of dimorphism button studding, comprise body, and at an end of body metric system pin thread screw thread is arranged, at the other end of body pin thread screw thread made in Great Britain is arranged.
Be further optimization and/or improvements below to above-mentioned utility model technical scheme:
On the above-mentioned metric system pin thread screw thread metric system nut can be installed, on pin thread screw thread made in Great Britain, nut made in Great Britain be installed.
The length of above-mentioned body can be 230 millimeters.
The length of above-mentioned metric system pin thread screw thread can be 90 millimeters.
The length of above-mentioned pin thread screw thread made in Great Britain can be 80 millimeters.
The utility model reasonable and compact in structure, one end are pin thread screw thread made in Great Britain, and the other end is a metric system pin thread screw thread, can change by actual conditions, need not to change studding, have therefore reduced workload, have saved engineering time and cost.
Description of drawings
Accompanying drawing 1 is the main TV structure schematic diagram of the utility model most preferred embodiment.
Coding in the accompanying drawing is respectively: 1 is body, and 2 is metric system pin thread screw thread, and 3 is pin thread screw thread made in Great Britain, and L is the length of body, and B1 is the length of metric system pin thread screw thread 2, and B2 is the length of pin thread screw thread 3 made in Great Britain.
The specific embodiment
The utility model is not subjected to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.
In the utility model, for convenience of description, the description of the relative position relation of each parts all is that the Butut mode according to Figure of description is described, as: the position relation of upper and lower, left and right etc. is what to determine according to the Butut direction of Figure of description.
Below in conjunction with embodiment and accompanying drawing the utility model is further described:
As shown in Figure 1, this dimorphism button studding comprises body 1, end at body 1 has metric system pin thread screw thread 2, the other end at body 1 has pin thread screw thread 3 made in Great Britain, like this, when the screwed hole screw thread on annular preventer top was inch screw thread, available pin thread screw thread 3 made in Great Britain of the present utility model was attached thereto, and when the screwed hole screw thread on annular preventer top was metric thread, available metric system pin thread screw thread 2 of the present utility model was attached thereto.
Can according to actual needs above-mentioned dimorphism button studding be made further optimization and/or improvements:
As shown in Figure 1, as required, on metric system pin thread screw thread 2, the metric system nut is installed, on pin thread screw thread 3 made in Great Britain, nut made in Great Britain is installed.
As shown in Figure 1, as required, the length L of body 1 is 230 millimeters.
As shown in Figure 1, as required, the length B1 of metric system pin thread screw thread 2 is 90 millimeters.
As shown in Figure 1, as required, the length B2 of pin thread screw thread 3 made in Great Britain is 80 millimeters.
Above technical characterictic has constituted most preferred embodiment of the present utility model, and it has stronger compliance and best implementation result, can increase and decrease non-essential technical characterictic according to actual needs, satisfies the demand of different situations.
