Abstract
The utility model relates to a spherical rubber core component of a universal blowout preventer, which solves the technical problems that the intensity of a seal rubber core component is low, the heat-resistant and cold-resistant performance is low, and therefore a rubber core is easily ruptured and torn. The technical scheme is as follows: the spherical rubber core component structurally comprises a rubber body and rigid support bodies with concave cambered surfaces, wherein the rigid support bodies are equidistantly arranged in a circular shape in the rubber body at the bottom to form a spherical-crown-shaped spherical rubber core body. The spherical rubber core component is characterized in that abrasion-resistant packing made of flexible abrasion-resistant fibers is additionally arranged in the rubber body. The spherical rubber core component has the beneficial effects that the service life of the rubber core is prolonged by one time, the common rubber core can only pass through 200-500 pairs of hoops, and the rubber core of the utility model can pass through 1000-2000 pairs of hoops; the common abrasion-resistant drill only reaches 1000m, and the product can reach 3000m; and the intensity of the Kevlar fiber is five times the intensity of the steel fiber with the same weight, the density of the Kevlar fiber is very low, and the Kevlar fiber has a high fracture extension degree, so the abrasion-resistant performance is greatly increased besides high intensity.
Description
Technical field
The utility model belongs to the spherical glue core assembly that the oil field prevents the drilling technology field, particularly a kind of omnipotent preventer of blowout.
Background technology
The packing unit assembly is located on the omnipotent preventer, and it and top cover, housing, piston, support ring are formed omnipotent preventer.The packing unit assembly plays the effect of inwardly holding the sealing drilling tool tightly in preventer.The packing unit assembly is an annular or tapered assemblies, is made of polylith brace rod and rubber, and each brace rod is distributed in the rubber uniformly, and rubber is bonded as a black box by fluid technology and polylith brace rod.Existing low, the heat-resisting cold tolerance of packing unit assembly intensity is low, thereby easily causes the embrittlement of glue core and tear, and application life is very short.
Summary of the invention
The utility model is low for solving low, the heat-resisting cold tolerance of packing unit assembly intensity, thereby the technical problem that easily causes the embrittlement of glue core and tear, designed a kind of spherical glue core assembly of omnipotent preventer, by in rubber bodies, setting up the Kafra fiber of wear-resisting tension, strengthen the sealing performance of packing unit, prolonged the application life of packing unit.
The utility model for realizing the technical scheme that goal of the invention adopts is, the spherical glue core assembly of omnipotent preventer, comprise rubber bodies in the structure, have the rigid support of inner concave arc surface, rigid support is equidistant and be circular arranged distribution form spherical crown shape sphere glue core body in the rubber bodies of bottom, and key is: have additional in the described rubber bodies by the abrasion resistant fibrous wear-resisting glove of making that adds of flexibility.
The beneficial effects of the utility model are: the glue core life-span doubles, and common glue core only can be by 200 ~ 500 pairs of joint hoops, and this product glue core can be by 1000 ~ 2000 pairs of joint hoops, and common wear-resisting brill removes about 1000 meters, and this product can reach 3000 meters; Because Kafra fiber is 5 dual intensities of steel fibre under the identical weight, and the density that Kev draws is very low, and has the very high ductility of breaking, except high strength, anti-wear performance improves greatly.
Below in conjunction with accompanying drawing the utility model is elaborated.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 be among Fig. 1 A-A to generalized section.
In the accompanying drawing, 1 represents rigid support, and 2 represent rubber bodies, the wear-resisting glove that adds of 3 representatives, and through hole is reinforced in the 3-1 representative.
The specific embodiment
The spherical glue core assembly of omnipotent preventer, comprise rubber bodies 2 in the structure, have the rigid support 1 of inner concave arc surface, rigid support 1 is equidistant and be circular arranged distribution form spherical crown shape sphere glue core body in the rubber bodies 2 of bottom, has additional in the described rubber bodies 2 by the abrasion resistant fibrous wear-resisting glove of making 3 that adds of flexibility.
Described flexibility is abrasion resistant fibrous to be Kafra fiber.
The described wear-resisting glove 3 that adds is evenly distributed between the rubber bodies 2 between the adjacent rigid supporter 1.
The described wear-resisting glove 3 that adds is arranged between rubber bodies 2 and the rigid support 1, forms wear-resistant structure.
The described wear-resisting glove 3 that adds is distributed in the rubber bodies 2 in the form of sheets, and wear-resisting glove 3 bodies that add are provided with reinforcing through hole 3-1.
Specific embodiment of the utility model: add Kafra fiber in the rubber between rigid support 1 and add glove, adding glove is evenly distributed in the rubber bodies between the rigid support 1, rigid support 1 and add glove and rubber bodies is sulfided into an annular or tapered assemblies, the wear-resisting reinforcing through hole 3-1 that adds glove 3 is full of rubber in sulfidation, with firm the combining of rubber bodies.
