Description

Pipeline connecting piece

Technical Field

The utility model relates to a pipe connection accessory field especially relates to a pipe connection spare.

Background

The connecting mode of the pipeline is extrusion type, thread type, flange type, argon arc welding type, rolling type and groove type. The thread type is the most common at present, the thread connection is usually realized by directly adopting a threaded pipeline and a sleeve nut, and a polytetrafluoroethylene raw material belt is wound between the pipeline and the sleeve nut to achieve the purpose of connection.

The technical scheme is not suitable for being used because the pipeline is not easy to screw when the pipeline is too long or the diameter is too large. In order to make the pipeline connection convenient, sanitary without dead angle, high sealing degree and strong shock resistance and pressure resistance, a new technical scheme is provided.

SUMMERY OF THE UTILITY MODEL

The utility model discloses an overcome above-mentioned prior art at least one kind defect (not enough), provide a pipe connection spare.

In order to solve the technical problem, the technical scheme of the utility model as follows:

the utility model provides a pipeline connecting piece, is female and the pipeline including the cover, the pipe end of pipeline forms the flange, the cover is equipped with the thread bush on the pipeline, the one end of thread bush with the flange butt, female and thread bush threaded connection of cover for the structure is firm, antidetonation resistance to compression, while easy to assemble and dismantlement. Be equipped with protruding circle in the cover mother, protruding circle can with the flange butt, be equipped with first gasket between flange and the protruding circle, improve the leakproofness of pipeline, prevent to reveal, prevent to form good buffering simultaneously, be favorable to the stability of whole structure.

As preferred technical scheme, the inner wall of pipeline flushes with the surface of protruding circle for the pipeline does not have sanitary dead angle.

As preferred technical scheme, the one end of thread bush with be equipped with the second gasket between the flange, improve the leakproofness of pipeline, prevent to reveal, prevent to form good buffering simultaneously, be favorable to the stability of overall structure. Preferably, the other end of the threaded sleeve is provided with a protruding ring body, and the protruding ring body is abutted to the port of the female sleeve, so that the whole structure is more stable.

As preferred technical scheme, the circumference of the female outer wall of cover and the circumference of the outer wall of the thread bush other end are equipped with and are convenient for the structure of the female and thread bush installation of cover or dismantlement. More preferably, the structure is in the shape of a hexagon head bolt. More preferably, the other end of the threaded sleeve protrudes axially to form a plurality of convex teeth, so that the threaded sleeve is more convenient to mount and dismount.

As preferred technical scheme, the cover is female can carry out threaded connection with two thread bush, and the cover is female wholly to be a straight line, can be with two straight connections of pipeline. More preferably, the sleeve nut is in a shape of 'Γ', and the convex ring is in a shape of 'Γ', so that two pipelines in ninety degrees can be connected.

Compared with the prior art, the utility model discloses technical scheme's beneficial effect is:

the utility model has the advantages of connect convenient, the health does not have the dead angle, sealing degree is high, antidetonation compressive capacity is strong, made apparent progress for prior art.

Example 1:

referring to fig. 1, the pipe connector of the present embodiment includes a nut 1 and a pipe 2, a flange 2a is formed at a pipe end of the pipe 2, a threaded sleeve 3 is sleeved on the pipe 2, one end 3a of the threaded sleeve abuts against the flange 2a, and the nut 1 and the threaded sleeve 3 are connected by threads. A convex ring 1a is arranged in the sleeve nut, the convex ring 1a can be abutted to the flange 2a, and a first gasket 4 is arranged between the flange 2a and the convex ring 1 a. The inner wall of the pipe 2 is flush with the surface of the collar 1 a. Further, a second gasket 5 is arranged between one end 3a of the threaded sleeve and the flange 2 a. The circumference of the outer wall of the sleeve nut 1 and the circumference of the outer wall of the other end 3b of the threaded sleeve are provided with structures which are convenient for the installation or the disassembly of the sleeve nut and the threaded sleeve. The structure is in a hexagon head bolt shape. The other end of the threaded sleeve protrudes towards the axial direction to form a plurality of convex teeth.

Example 2:

referring to fig. 2, the difference between embodiment 2 and embodiment 1 is that the sleeve nut 1 can be screwed with two threaded sleeves 3. The whole sleeve nut 1 is a straight line and can straightly connect the two pipelines 2.

Example 3:

referring to fig. 3, embodiment 3 is different from embodiment 1 in that the sleeve nut 1 can be screwed to two threaded sleeves 3, the sleeve nut 1 is "Γ" shaped, and the cross section of the collar 1a is "Γ" shaped. Two ninety degree tubes 2 may be connected.
