Abstract
The invention discloses a low-pressure pipeline pressure ring seal quick connector for petroleum drilling and production operation. The low-pressure pipeline pressure ring seal quick connector comprises a connecting male connector, a sealing ring, a pressure ring, a connecting nut and a connecting pipe. One side, in contact with the sealing ring, of the male connector is connected with the pressure ring, the male joint is connected with the connecting nut through threads, by screwing in the connecting nut to push the pressure ring to press the sealing ring, the sealing ring is inwards deformed to press the connecting pipe and thus sealed connection between the connecting male connector and the connecting pipe is realized. The low-pressure pipeline pressure ring seal quick connector has the advantages that the nut screwing torque is small, the sealing reliability is high, the connector is convenient to assemble and disassemble, and the sealing pressure can reach 1MPa.
Description
Technical field
The present invention relates to joint, be used in the mud cleaning system of petroleum drilling operation.
Background technique
The low-pressure line joint being used in petroleum drilling operation is at present pneumatic tyre type union, and its deficiency is the easy explosion of pneumatic tyre or gas leakage, causes pipeline seal failure, and changes pneumatic tyre difficulty, and mud loss is large.
Summary of the invention
The object of the invention be to provide a kind of dismounting convenient, seal reliable low-pressure line pressure ring sealing fast connector.
In order to reach as above object, the present invention takes following technological scheme: it comprises tool joint pin, seal ring, pressure ring, attaching nut, and the side of tool joint pin Contact Seal ring connects with pressure ring, and tool joint pin and attaching nut are threaded connection.
Further technological scheme of the present invention is: described attaching nut has can by the convex wing structure knocked.
Adopt the low-pressure line pressure ring sealing fast connector of as above technological scheme, have following beneficial effect: joint of the present invention, nut rotation torque is little, and sealing is reliable, and installing/dismounting is quick.Strong adaptability, easy maintenance.Have the attaching nut of convex wing structure under several with adze-eye hammer hammering, get final product reliable sealing, sealing load can reach 1MPa.
accompanying drawing illustrates:
In order to further illustrate the present invention, be described further below in conjunction with accompanying drawing:
Accompanying drawing is the structural representation of invention:
Wherein: 1 tool joint pin; 2 seal rings; 3 pressure rings; 4 attaching nuts; 5 connecting tubes.
embodiment:
As shown in the figure, low-pressure line pressure ring sealing fast connector of the present invention, it comprises tool joint pin 1, seal ring 2, pressure ring 3, attaching nut 4, and seal ring 2 side that tool joint pin 1 contacts connects with pressure ring 3, and tool joint pin 1 and attaching nut 4 are threaded connection.
Its structural principle is one end of tool joint pin 1 and container or steel-pipe welding, tool joint pin 1 and attaching nut 4 are threaded connection, and during attaching nut's 4 precession, promote pressure ring 3 press seal circle 2 and produce to internal strain, compress connecting tube 5, realize being tightly connected of tool joint pin l and connecting tube 5.
Described pressure ring 3 makes seal ring be extruded tightly, and therefore sealing effect is better, and when making attaching nut's 4 precession, moment of torsion is little.
Described attaching nut 4 has can, by the convex wing structure knocked, can make attaching nut screw reliably.
More than show and describe basic principle of the present invention, major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
