Description

MPP pipe convenient to welding

Technical Field

The utility model relates to a MPP pipe welding technology field, concretely relates to MPP pipe convenient to welding.

Background

The MPP pipe is also called as an MPP power cable protection pipe, the main raw material is modified polypropylene, the MPP pipe has the characteristics of high temperature resistance and external pressure resistance, and is suitable for a calandria pipe of a high-voltage transmission line cable with the voltage of more than 10 kV. The connected mode of current MPP pipe mainly has hot melt to connect and fixed head to connect two kinds, and when the connected mode of MPP pipe was hot melt to connect, use welding machine hot melt welding butt joint, need be with the help of the fixed MPP pipe rewelding of outside fixer, during welded connection simultaneously, because the vibration of equipment and the influence of welding thermal stress lead to the condition that welding mouth dislocation or interface pipeline cracked, intraductal leakproofness is destroyed, the damage cable conductor.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve the problem that proposes in the above-mentioned technical background, provide a MPP pipe convenient to welding, simple structure can carry out the accuracy to many tubular products fast and fix, makes things convenient for the operation personnel to weld MPP pipe, improves welding effect, save time.

The utility model adopts the following technical scheme:

the utility model provides a MPP pipe convenient to welding, includes the MPP pipe, MPP pipe one end is equipped with outer fixed head, and the other end is equipped with interior fixed head, outer fixed head inner wall is close MPP pipe port department and is equipped with opening ring groove, opening ring groove open end one side is equipped with one-way stationary blade, and the opposite side is equipped with the fixed plate, be equipped with the extension plate on the interior fixed head, be equipped with the joint boss on the extension plate, be equipped with stationary blade draw-in groove on the joint boss side.

As the utility model relates to a preferred technical scheme of MPP pipe convenient to welded, the circle footpath is greater than the interior circle footpath of MPP pipe in the external fixation head, the outer circle footpath of internal fixation head is less than MPP pipe outer circle footpath, external fixation head, internal fixation head and MPP pipe are concentric.

As the utility model relates to a preferred technical scheme of MPP pipe convenient to welded, opening ring groove opening is the same with joint boss quantity, and the equidistance distributes.

As a preferred technical scheme of MPP pipe convenient to welded, one-way stationary blade is established on MPP pipe terminal surface, one-way stationary blade is elastic material.

As the utility model relates to a be convenient for the preferred technical scheme of welded MPP pipe, joint boss terminal surface and MPP pipe end face laminating are fixed.

The utility model has the advantages that:

the utility model relates to a MPP pipe convenient to welding adopts the fixed form of draw-in groove ka tai joint, can carry out the accuracy fast to many tubular products and fix, uses the elastic fixation piece fixed simultaneously, lets the MPP pipe not shift when the welding, improves the welding effect.

Drawings

Fig. 1 is a schematic structural view of an MPP tube convenient to weld according to the present invention;

the symbols in the drawings illustrate that: MPP pipe 1, outer fixed head 2, interior fixed head 3, opening ring groove 4, one-way stationary blade 5, fixed plate 6, extension plate 7, joint boss 8, stationary blade draw-in groove 9.

Detailed Description

The invention will now be described in further detail with reference to the accompanying drawings.

As shown in fig. 1, an MPP pipe convenient to welding, including MPP pipe 1, 1 one end of MPP pipe is equipped with external fixation head 2, and the other end is equipped with internal fixation head 3, 2 inner walls of external fixation head are close 1 mouth department of MPP pipe end and are equipped with opening ring groove 4, 4 open end one sides of opening ring groove are equipped with one-way stationary blade 5, and the opposite side is equipped with fixed plate 6, be equipped with extension plate 7 on the internal fixation head 3, be equipped with joint boss 8 on the extension plate 7, be equipped with stationary blade draw-in groove 9 on the joint boss 8 side.

Specifically, in this embodiment, circle footpath is greater than MPP pipe 1 inside circle footpath in the outer fixed head 2, the outer circle footpath of the internal fixation head 3 is less than MPP pipe 1 outside circle footpath, outer fixed head 2, internal fixation head 3 and MPP pipe 1 are concentric.

In this embodiment, the number of the openings of the open ring slots 4 is the same as that of the clamping bosses 8, and the openings are distributed at equal intervals.

In this embodiment, the one-way fixing piece 5 is disposed on the end surface of the MPP pipe 1, and the one-way fixing piece 5 is made of an elastic material.

In this embodiment, 8 terminal surfaces of joint boss and MPP pipe 1 terminal surface laminating are fixed.

The specific implementation mode is as follows: prepare the work before the welding, then with the butt joint of the MPP pipe of two different ports, the joint boss pushes away an annular draw-in groove opening part, then rotatory MPP pipe, the one-way stationary blade of extrusion, with the joint boss revolve to the space that opening annular draw-in groove and fixed plate formed in, the one-way stationary blade reconversion of this moment, the card is on the stationary blade draw-in groove, lets the MPP pipe not shift when the welding, improves the welding effect.

Finally, it should be noted that: these embodiments are merely illustrative of the present invention and do not limit the scope of the invention. In addition, other variations and modifications will be apparent to persons skilled in the art based on the foregoing description. And are neither required nor exhaustive of all embodiments. And obvious changes and modifications may be made without departing from the scope of the present invention.
