Description
Technical Field
The utility model relates to an oil is bored and is adopted accessory, concretely relates to oil is bored and is adopted union spare belongs to oil and bores and adopts accessory technical field.
Background
In an oil drilling and production operation exploitation manifold system, the connection mode adopted by the manifold system is divided into a welding type joint and a spiral type joint, but the welding type joint is very inconvenient in the processes of disassembly and reassembly; o-shaped sealing rings are mostly used in the spiral joints, and because the O-shaped sealing rings are made of rubber, the rubber can be aged after a long time or high temperature, and oil leakage is caused; the high-pressure union commonly used in China at present is mature in structure and process and wide in application; however, when the union male head and the union female head of the existing union piece are closed, the joint of the union piece is seriously leaked in a high-pressure state, and if a rubber sealing ring is arranged for protection, the rubber aging and corrosion conditions still exist in the using process of the union piece.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides an oil bores and adopts union piece, the female head of union and union adopts self structural seal and twice hard seal, and whole leakproofness is good.
The utility model discloses an oil drilling and production union piece, including union male head and union female head, and install in union male head and the union dish of union female head outside, the union male head and the union female head just set up the domatic of laminating each other respectively to one side; the union male head and the union female head are provided with an upper joint plane and a lower joint plane at the top and the bottom of the slope; a sealing pressure groove is formed right opposite to the two lower joint planes; an inner metal hard sealing ring is pressed in the sealing pressure groove; an open type external sealing groove is formed in the outer part of one side, opposite to the union male head and the union female head, of the union male head; rubber rings are sleeved at the inner corners of the two outer closed grooves; an outer metal hard sealing ring is arranged between the rubber rings; during assembly, an inner metal hard sealing ring is firstly sent into a sealing pressure groove of a union female head, then rubber rings are respectively sleeved on the union male head and the union female head, an outer metal hard sealing ring is placed above the rubber ring of the union female head, and finally a union disc penetrates through the union male head and is screwed with the union female head, so that three seals of the inner metal hard sealing ring, the slope and the outer metal hard sealing ring are formed; the outer metal hard seal ring is pressed between the two rubber rings.
Furthermore, at least one convex seat is integrally formed outside the union disc; at least one convex seat is communicated with the inner side of the union disc; a leakage observer is arranged on the inner side of the boss, when the union disc leaks, liquid enters the boss, and the liquid leakage can be observed through the leakage observer.
Further, the leakage observer is a transparent tube screwed on the top and the bottom of the boss; the two transparent tubes are communicated with the inner side of the boss, and whether the union part has large leakage or not can be determined by observing the transparent tubes.
Furthermore, the rubber ring and the outer metal hard sealing ring are externally wound with reinforcing packing, and external leakage prevention and final protection are performed by beating the reinforcing packing.
Compared with the prior art, the utility model discloses an oil bores and adopts union piece, adopts the bench formula contact with union male head and union female head, and self structure possesses better closure, sets up one hard seal simultaneously in the halfpace bottom, sets up the second in the halfpace outside and says hard seal, and whole leakproofness is good, high-pressure shock resistance.
