Abstract
The utility model discloses a fast joint for oil drilling and production operation, comprising a connecting pipe, a gland connected with the other mouth of the connecting pipe through a thread, as well as a through hole arranged on the middle part of a gland cover plate. The mouth of the connecting pipe where the gland is positioned has a horn-shaped conical surface structure, and a sealing ring is arranged between the horn-shaped conical surface and the gland cover plate. The fast joint has the advantages that as the mouth of the connecting pipe where the gland is positioned has the horn-shaped conical surface structure, when the gland is twisted, the O-shaped sealing ring moves in the axial direction of the conical surface at the same time when the O-shaped sealing ring is extruded and deformed, thereby raising sealing effect, and then the sealing pressure of the hand-twisted gland can reach 1.5 MPa; meanwhile, the friction force between the contact surfaces of the gland cover plate and the sealing ring is reduced, which increases the life span of the sealing ring and reduces the rotary twisting force of the gland. Therefore, sealing can be realized only by twisting a boss on the peripheral surface of the gland with a hand, and the fast joint is very convenient to install and detach.
Description
Technical field
The utility model relates to pipe joint, especially relates to the quick connector that is used for the petroleum drilling and mining operation.
Background technology
The quick connector that is used in the petroleum drilling and mining operation at present has three kinds of pneumatic tyre formula unions, I type paddle type mill union, II type paddle type mill union.The weak point of pneumatic tyre formula union is easy explosion of pneumatic tyre or gas leakage, causes the pneumatic tyre seal failure, and the mud loss is too big; The medium operating pressure is lower, is generally 0.3MPa.The medium operating pressure of I type paddle type mill union increases, and is 0.6MPa.But the I type paddle type mill union consumptive material of same specification is 3-4 times of pneumatic tyre formula union.II type paddle type mill union quite I type paddle type mill union has saved pressure ring and makes consumptive material reduce, but sealing load can only reach 0.5MPa, and the medium operating pressure is 0.3MPa; Because sealing ring is installed in the tube connector mouth of pipe inwall arc-shaped ring groove, the gland crush seal circle distortion at sealing tube mouth place realizes, so the sealing ring distortion is little, and sealing effectiveness is not good.
The utility model content
The utility model purpose is to provide the quick connector that is used for the petroleum drilling and mining operation that a kind of dismounting is convenient, operating pressure is high.
For achieving the above object, the utility model can be taked following technical proposals:
The quick connector that is used for the petroleum drilling and mining operation described in the utility model comprises tube connector and by being threadedly connected to the gland at another mouth of pipe place of described tube connector; And the through hole that is opened in described gland cover plate middle part; The tube connector mouth of pipe that is positioned at the gland end is horn-like cone structure; Between the described horn-like conical surface and gland cover plate, be provided with sealing ring.
Dismounting for convenient described gland is provided with boss vertically on the gland outer peripheral face.
The utility model advantage is that the tube connector mouth of pipe that is positioned at described gland end is set to horn-like cone structure, therefore in turn-knob gland process, " O " RunddichtringO moves axially along the conical surface in crimp, improved sealing effectiveness, hand-screw gland seal pressure can reach 1.5MPa, also reduced simultaneously the application life that the frictional force between gland cover plate and the sealing ring contact surface has improved sealing ring, reduced the rotary torsion of gland, make and adopt the boss on the described gland outer peripheral face of hand-screw can realize sealing, installing/dismounting is very convenient.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in the figure, the quick connector that is used for the petroleum drilling and mining operation described in the utility model, it comprises tube connector 1, a mouth of pipe of tube connector 1 is used for and connected container or pipeline welding.Another mouth of pipe is by the gland 2 that is threaded; Offer at described gland cover plate 3 middle parts and to be used for the through hole 4 that connected pipe penetrates; The mouth of pipe that is positioned at the tube connector 1 of gland 2 ends is the horn-like conical surface 5 structures; Between the described horn-like conical surface 5 and gland cover plate 3, be provided with " O " RunddichtringO 6; On gland 2 outer peripheral faces, be provided with boss 7 vertically.
Claims (2)
1, a kind of quick connector that is used for the petroleum drilling and mining operation, it comprises tube connector (1), by being threadedly connected to the gland (2) at described tube connector (1) one mouth of pipe place; And the through hole (4) that is opened in described gland cover plate (3) middle part; It is characterized in that: the tube connector mouth of pipe that is positioned at gland (2) end is the horn-like conical surface (a 5) structure; Between the described horn-like conical surface (5) and gland cover plate (3), be provided with sealing ring (6).
