Abstract
A high-pressure elbow sealer comprises an inner pipe, an outer pipe, steel balls, sealing plugs, wire plugs, clamp springs, a sealing spacer and an elastic corrugated spacer, wherein two corresponding annular semicircular round grooves are respectively formed in the outer pipe and the outer pipe, and circular steps are formed in the annular semicircular groove of the outer pipe. The elastic corrugated spacer and the U-shaped sealing plugs are arranged in the steps, an annular boss is arranged on the end surface of the inner pipe to be matched with the sealing spacer, through holes are respectively formed in the circumference, corresponding to the annular round grooves, of the outer pipe, a plurality of the steel balls are placed from the through holes and enable the inner pipe and the outer pipe to be movably connected, the annular sealing plugs which are provided with inner threaded holes are placed in the through holes, the wire plugs are screwed in the inner threaded holes, and the sealing plugs are positioned through the clamp springs. The high-pressure elbow sealer has the advantages of being novel in design, reasonable in structure, capable of solving the problems that the sealing is poor and a working medium is stabbed and leaked out of the high-pressure elbow sealer under the low-pressure condition, capable of avoiding the loss of oil and water and environmental pollution, and long in service life.
Description
Technical field
The utility model relates to the high pressure movable elbow Sealing Technology of using in oil field operation, the drilling process, particularly is a kind of high pressure elbow sealer.
Background technology
The high pressure movable elbow is used for cementing truck, fracturing unit truck, various manifolds, pipeline and other high-tension apparatus, it is the important pipe fitting of transferring oil, water, fracturing fluid and mixing material, in use, the high pressure movable elbow is realized pretension after relying on end face " U " RunddichtringO that is installed in the high pressure movable elbow to expand under the fluid pressure effect.Under low-pressure, it is limited that end face " U " RunddichtringO expands, and causes poor sealing and cause the working media thorn to leak, and causes environment pollution, the requirement that inconsistent oilfield safety environmental protection zero is polluted.Therefore, existing high pressure movable elbow structure can't solve the technical barrier that the low pressure thorn leaks.
Summary of the invention
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, has designed a kind of high pressure elbow sealer.
The utility model comprises: interior pipe, outer tube, steel ball, sealing-plug, plug, jump ring, sealing mat, elastic corrugated pad.Its high pressure elbow sealer namely is respectively equipped with the annular half slot of twice correspondence at interior pipe, outer tube, annular half slot the inside of outer tube is provided with ring-shaped step, be placed with elastic corrugated pad, " U " grommet type seal in the step, the inner tube face is provided with annular boss and cooperates with sealing mat, the corresponding annular half slot of outer tube excircle respectively is provided with a through hole, several steel balls are put into from through hole, interior pipe, outer tube are flexibly connected, pack in the through hole and be provided with the ring sealing plug of internal thread hole, be convenient to the lubrication oil of annotating, plug screws in internal thread hole, by jump ring sealing-plug is located.
The beneficial effects of the utility model are: modern design, and rational in infrastructure, solved high pressure movable elbow poor sealing working media thorn leakage problem under low pressure, avoid oil, water loss and environment pollution, long service life.
Description of drawings
Fig. 1-the utility model master looks the complete section structural representation.
Among the figure, 1. in pipe, 2. outer tube, 3. steel ball, 4. sealing-plug, 5. plug, 6. jump ring, 7. sealing mat, 8. elastic corrugated pad; A. annular half slot.
The specific embodiment
Below in conjunction with accompanying drawing enforcement of the present utility model is further elaborated:
The high pressure elbow sealer is made up of interior pipe 1, outer tube 2, steel ball 3, sealing-plug 4, plug 5, jump ring 6, sealing mat 7, elastic corrugated pad 8.Its high pressure elbow sealer namely is respectively equipped with the annular half slot A of twice correspondence at interior pipe 1, outer tube 2, annular half slot A the inside of outer tube 2 is provided with ring-shaped step, be placed with elastic corrugated pad 8, " U " grommet type seal 7 in the step, interior pipe 1 end face is provided with annular boss and cooperates with sealing mat 7, the corresponding annular half slot A of outer tube 2 excircles respectively is provided with a through hole, several steel balls 3 are put into from through hole, interior pipe 1, outer tube 2 are flexibly connected, the ring sealing plug 4 of packing in the through hole and being provided with internal thread hole, plug 5 screws in internal thread hole, by jump ring 6 sealing-plug 4 is located.
