Abstract
The utility model discloses a separate bottom flange, which consists of a flange body, a ring flange and an adjusting ring; the flange body consists of a connecting end surface part and a neck part; the outer periphery of the connecting end surface part of the flange body is provided with a ledge, and the inner periphery of the ring flange is provided with a spigot; and when the bottom flange is used, the adjusting ring is clamped between the ledge and the spigot. Since the bottom flange adopts a separate structure, when the flange body is damaged and cannot be repaired, the flange body can bereplaced, the ring flange still can be used, consequently, the repairability of the bottom flange is enhanced, and the use cost is reduced for users. On the other hand, by replacing different adjusting rings, a flange body can be connected with ring flanges with different sizes, or a ring flange can be connected with flange bodies with different sizes, consequently, bottom flanges with various specifications can be quickly assembled, and the efficiency of the production preparation of manufacturers is greatly increased.
Description
Technical field
The utility model relates to oil drilling well control device technical field, relates in particular to a kind of end flange that is connected between preventer and the surface pipe.
Background technology
At present, in oil drilling, well head need be installed preventer.Preventer is installed on the flange of end flange, and neck endoporus place's turning of end flange has casing threads, and this casing threads is used for being connected with two public pipe nipples, and two public pipe nipples are connected with surface pipe again.So-called " two public pipe nipple " is actually one and is convenient to the pipe fitting that is connected with inner thread piece, is respectively equipped with external screw thread at the two ends of this pipe fitting.
Because end flange is threaded with two public pipe nipples, damages easily in unloading process, if the thread damage on the end flange neck endoporus just must be keeped in repair.One of method of maintenance will have the end flange neck turning of screw thread exactly and remove part or all, but so, the height of end flange will reduce, after being reduced to certain standard, although other position of end flange is excellent, flange of the whole end also will be scrapped, therefore, the end flange of monolithic construction, its maintenanceability is poor, has brought very big use cost to the user.
In addition, be under pressure at least restriction of rank, latus rectum and three indexs of connecting thread of the size of end flange because the oil well index has nothing in common with each other, therefore, has caused the too many situation of end flange specification.This situation, headache more concerning manufacturer if the specification of preparing is too much, must take substantial contribution, influence business capital and has enough to meet the need; If the specification of preparing is very few, in case need, be subjected to the restriction of process time, be difficult to make fast reaction, and influence the time of delivery.
Summary of the invention
Technical problem to be solved in the utility model is: flange of a kind of split type end is provided, to improve the maintenanceability of end flange, reduces user's use cost, and improve the production preparation efficient of producer.
For solving the problems of the technologies described above, the technical solution of the utility model is: flange of the split type end, comprise flange body, and described flange body comprises link face and neck; Flange; Described flange body is provided with a flange on the outer peripheral face of link face, described flange is provided with a seam on inner peripheral surface, during use, and described flange and described seam clamping.
Wherein, flange of the described end comprises that is also adjusted a circle, and during use, described adjustment circle is connected between described flange and the described seam.
After having adopted technique scheme, the beneficial effects of the utility model are: because described flange body is provided with a flange on the outer peripheral face of link face, described flange is provided with a seam on inner peripheral surface, during use, described flange and described seam clamping, thus the sealing and the linkage function of end flange guaranteed.If because dismounting has destroyed the screw thread on the end flange neck endoporus, under situation about can't repair, only need to change flange body, flange is still available, thereby improves the maintenanceability of end flange, reduce user's use cost, as producer, only need to prepare flange body, thereby can reduce difficulty of processing, shorten the process-cycle, improve to produce and prepare efficient.
Simultaneously, because flange of the described end comprises that is also adjusted a circle, by changing different adjustment circles, the flange of a flange body and different size can be coupled together, perhaps the flange body with a flange and different size couples together, thereby be combined into the end flange of a plurality of specifications apace, further improved the efficient that manufacturer production is prepared.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structure sectional view of the utility model first embodiment;
Fig. 2 is the structure sectional view of the utility model second embodiment;
Among the figure: 1. flange body; 2. flange; 3. adjust circle; 11. connecting thread; 12. connection end face.
The specific embodiment
First embodiment:
As shown in Figure 1, flange of a kind of split type end, it comprises flange body 1, flange 2 and adjusts circle 3.Described flange body 1 comprises link face and neck; Connect the end face that end face 12 is positioned at the link face, be used for being connected with preventer and sealing; Connecting thread 11 is arranged on the described neck endoporus, is used for being connected with two public pipe nipples; Described flange body 1 is provided with a flange on the outer peripheral face of link face, described flange is provided with a seam on inner peripheral surface, during use, and described flange and described seam clamping.
Second embodiment:
As shown in Figure 2, the structure of second embodiment and first embodiment are basic identical, and its difference is to have increased by one and adjusts circle 3, and during use, described adjustment circle 3 is connected between described flange and the described seam.
End flange adopts after the above-mentioned split-type structural, on the one hand, when the flange body damage can't be repaired, only needs to change flange body, and flange is still available, thereby improves the maintenanceability of end flange, minimizing user's use cost.On the other hand, by changing different adjustment circles, the flange of a flange body and different size can be coupled together, perhaps the flange body with a flange and different size couples together, thereby can be combined into the end flange of a plurality of specifications apace, improve the efficient that manufacturer production is prepared greatly.
