Description

Integral type back taper connects

Technical Field

the utility model relates to a pipe fitting attach fitting, the be connected of specially adapted interface and pipe fitting.

Background

During mechanical assembly, the pipe fitting and the interface are often connected in a sealing manner, and a sealing ring and a reverse taper joint are usually required. Need once only to install fixedly during the use, if the condition that does not install well or not sealed good appears, then need pull down back taper joint and sealing washer and install again, often the sealing washer has deformed to can not use or the jam is difficult to take out in the interface, greatly increased operating personnel's work load, also increased the consumption of sealing washer simultaneously.

Moreover, to make the sealing ring can be fine with pipe fitting and interface connection and complete sealing clearance, then need with the interface face that the sealing ring pasted mutually enough level and smooth, can make the contact surface completely sealed, otherwise the condition of junction gas leakage or weeping appears very easily, this greatly increased the processing degree of difficulty of interface and sealing ring.

Disclosure of Invention

In view of the above problems, the present application provides a convenient and practical pipe fitting joint.

the utility model discloses a concrete technical scheme as follows:

Integral type back taper connects for with pipe fitting and pipe fitting interface connection, this back taper joint is cavity, and the main part is the screw thread section, and the screw thread section is equipped with round platform shape structure and ring structure forward in proper order, and the screw thread section is equipped with circular bead and fastening components backward in proper order, and back taper connects each part to be integrated into one piece.

preferably, still include and connect the cooperation with the back taper and be equipped with the pipe fitting interface, the inner structure and the back taper of pipe fitting interface connect looks adaptation, and the pipe fitting interface is including the first cylindrical cavity, toper chamber and the second cylindrical cavity that set gradually.

Preferably, R1> R2 is required between the caliber R1 of the inverted cone joint circular ring structure and the minimum caliber R2 of the pipe fitting interface conical cavity.

Preferably, the caliber of the reverse taper joint thread section is matched with the caliber R3 of the first cylindrical cavity of the pipe joint.

Preferably, the material of the inverted cone connector is plastic, aluminum or copper.

the utility model discloses following beneficial effect has:

During the use, insert the back taper with the pipe fitting and connect to aim at with the inner chamber of interface, make the ring shape structure edge paste with the interface inclined plane mutually, rotatory propulsion fastening component makes the ring shape structure atress move forward, and the edge of ring structure produces deformation because of receiving the extrusion, and then extrudees the pipe fitting interface, reaches the effect of fixed and sealed pipe fitting.

In the pipe connecting process of the utility model, no extra sealing ring is needed, and the integrated inverted cone joint can be used for many times, thereby saving the cost; the situation that the compression ring is difficult to take out of the interface after being deformed can not occur during disassembly, so that the assembly and disassembly of operators are more convenient; the edge deformation of the circular ring structure is utilized to play a role of line sealing, the defect that the service surface of the connector is sealed in the past is overcome, the sealing effect is better, and meanwhile, the machining precision requirements of the interface and the inverted cone connector are greatly reduced.

Detailed Description

The first embodiment is as follows:

as shown in fig. 1, the utility model discloses an integral type back taper connects for with pipe fitting and pipe fitting interface connection, the back taper connects and is cavity, and the main part is screw thread section 4, and round platform shape structure 3 and ring structure 2 are established to the screw thread section front end, and round platform shape structure small-bore end is towards ring structure. The rear end of the thread section is provided with a shoulder and a fastening part 5, and all parts can be integrally formed by adopting a die, so that the processing is convenient.

example two:

Optionally, in this embodiment, the material of the integral inverted cone connector is made of plastic, aluminum material or copper material.

example three:

Optionally, the present embodiment designs a pipe interface structure, as shown in fig. 2, the pipe interface structure includes three sections, namely a first cylindrical cavity 7, a tapered cavity 8, and a second cylindrical cavity 9. The existing interface structure is improved, the annular structure in the joint pressing ring is pressed through the inclined plane of the inner wall of the conical cavity, and an annular cavity is not arranged in the pipe fitting interface.

Example four:

Optionally, in this embodiment, as shown in fig. 3, R1> R2 needs to be satisfied between the caliber R1 of the inverted cone-shaped joint circular ring structure and the minimum caliber R2 of the pipe fitting interface tapered cavity, so as to utilize the edge deformation of the circular ring structure to perform the line sealing function.
