Abstract
The utility model relates to an infix device of blowout prevention in oil field, in particular to a casing assembly of ram blowout preventer, which consists of a casing, a top seal base loop, a lock ring, a press bolt and a seal loop. The top seal base loop is arranged inside the body of the casing arranged on the end face of the casing. A tungsten-chromium-cobalt alloy coat is build-up welded on the end face of the top seal base loop. The top seal base loop is fixed with the casing by the lock ring and the press bolt. The utility model has the advantages that the top seal base loop can be detached from the casing, changed, manufactured and maintained conveniently. An elastic seal loop is arranged to reduce the wear between the seal loop and the top seal base loop to the maximum degree when the ram moves, thereby prolonging the life span of the top seal base loop.
Description
Technical field
The utility model relates to the housing unit of the drilling rig that a kind of oil field prevents blowout, particularly a kind of ram blowout preventer.
Background technology
Generally apart from ground three, four meters high of the positions at preventer place in drilling rig, the volume of housing is very huge, is a large component, generally weighs more than ten ton.In installing and using, owing to be subjected to the restriction of drilling rig working platform, the difficulty of installation and maintenance is quite big.The housing of existing preventer, as a whole part is owing to be applied in the oil drilling machinery, quite high to the requirement of the corrosion resistance of housing part and anti-wear performance.The particularly top of housing end face sealing directly contacts with medium during work, directly bears the impacting with high pressure of medium, is perishable, a rapid wear face.For anti-rotten, the anti-wear performance in the surface of improving the housing end face, on the end face surface of housing, generally need anti-rotten, the wear-resisting tungsten-chromium-cobalt alloy coating of surfacing one deck, to improve the application life of housing, technological requirement, difficulty of processing that surface spraying weld is handled are quite high.Because the part of housing is very big, and is again directly directly to carry out the surfacing coating on housing, so in case end face is damaged, leakage phenomenon occurs, whole housing is promptly scrapped.If housing is dismantled maintenance, must meet again the weldering on the end face and detect a flaw, find out crack; again weld again, eliminate stress; but be difficult at the scene finish for this a series of maintenance procedures, like this, certainly will will cause shutdown maintenance.For this large-scale component, general user also can not have a plurality of acknowledgment copies and be used for changing, so maintenance is quite difficult, and the use cost height.
Summary of the invention
Technical barrier to be solved in the utility model is, overcome in the prior art and cause whole deficiency of scrapping of housing because of alloy coat face rapid wear, a kind of housing unit with top seal holder ring and removable ram blowout preventer is provided, with the alloy coat surfacing on the seal holder ring of top, by screw the top seal holder ring is fixed on the housing again, make it to constitute the housing unit of a band top seal holder ring,, can from housing, the top seal holder ring be pulled down replacing easily in case the top seal holder ring damages.
Technical solution of the present utility model is, is provided with housing, is provided with the top seal holder ring in the enclosure body of housing end, and the end face of top seal holder ring is provided with alloy coat, and housing and top seal holder ring are fixedly connected; The top seal holder ring is provided with sealing ring with combining of housing between the end face.
Alloy coat on the seal holder ring end face of described top is tungsten-chromium-cobalt alloy coating.
Be respectively equipped with the annular groove that correspondence matches on housing and the top seal holder ring, be provided with the open type retaining ring in its annular groove, and be respectively equipped with the cammed surface that can cooperatively interact on the retaining ring and on the annular groove of housing; The top seal holder ring is provided with the hold-down bolt that can compress retaining ring, makes it to be fixedly connected by hold-down bolt and retaining ring between top seal holder ring and the housing.
Described top seal holder ring is an O type circle with the sealing ring that combines between the end face of housing, and is arranged in the seal groove on the seal holder ring of top.
The utility model advantage compared with prior art, the one,, the top seal holder ring that has an alloy coat is detachable from the housing, replaceable, in case the top seal holder ring damages, can change the top sealing ring at the scene, oil field, and easily convenient, complete machine need not stop during replacing.
The 2nd,, owing to change the rapid wear face of big of housing into removable smallclothes consumable accessory, make when occurring leaking maintenance very convenient, the top seal holder ring that only need change rapid wear gets final product, make field maintenance omit the original bigger activitiess of difficulty such as detecting a flaw again, weld, eliminate stress, greatly reduce use, maintenance cost whole of housing.
The 3rd,, the Enhancement Method of top seal, the top is sealed in avoid in the process that flashboard moves with the top seal holder ring tension on crisscross, can reduces the wearing and tearing of top seal and top seal holder ring to greatest extent, make the long service life of top seal holder ring.
The drawing explanation
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing of Fig. 1.
Specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment further is described in detail:
The utility model is made of housing 3, top seal holder ring 1, retaining ring 4, hold-down bolt 5 and sealing ring 2.Top seal holder ring 1 is located in the enclosure body of housing 3 ends, and makes it to fix by hold-down bolt 5 and retaining ring 4.In order to increase anti-corruption, the anti-wear performance of top seal holder ring 1, the end face of top seal holder ring 1 is provided with tungsten-chromium-cobalt alloy coating 7.
Top seal holder ring 1 makes it to be fixed on the housing 3 by interior hexagonal hold-down bolt 5 and retaining ring 4.Be respectively equipped with the annular groove that correspondence matches on housing 3 and the top seal holder ring 1, be provided with open type retaining ring 4 in its annular groove.Top seal holder ring 1 is provided with four interior hexagonal hold-down bolts 5, compresses retaining ring 4 by hold-down bolt 5, so that compress between housing 3 and the top seal holder ring 1, so make it relative fixed, sealing.For guaranteeing the adhesion and the sealing of 3 of top seal holder ring 1 and housings, also be respectively equipped with the cammed surface 6 that can cooperatively interact on the retaining ring 4 and on the annular groove of housing 3.
For increasing the sealing performance of top seal holder ring 1, reduce the wearing and tearing of top seal holder ring 1 simultaneously, two side end faces that top seal holder ring 1 combines with housing 3 are provided with " O " RunddichtringO 2, the seal groove of its setting " O " RunddichtringO 2 is located on the top seal holder ring 1, can realize 3 positiver sealings of top seal holder ring 1 and housing.
The utility model is located at the rapid wear face 7 on the housing 3 on the top seal holder ring 1 because the part of top seal holder ring 1 is little, can be very convenient from the preventer dismounting and change, so solved the deficiency that 3 whole rapid wears of housing are difficult to keep in repair effectively.When changing top seal holder ring 1,, pull down four interior hexagonal hold-down bolts 5 on the top seal holder ring 1, promptly detachably descend top seal holder ring 1 as long as open the side door of preventer, very convenient, in the application life of having improved housing 3, reduced cost.
