Abstract

The utility model discloses the PE pipe of band one Upsetting head, comprise tubing and loose flange, tubing head end establishes Upsetting head, Upsetting head is protruding step, exterior edge face is junction surface, junction surface is communicated with endoporus, loose flange is sleeved on the outer wall of tubing, on establish some mounting holes, mounting hole is through hole, the Upsetting head that tubing and head end are established is integrated shape, processed by the tubing hot melt of through state without Upsetting head, loose flange endoporus is greater than the external diameter of tubing, the utility model is integral type, solve without the effective welding of PE of Upsetting head or splitting or loosening of Kraft connection, or the obscission of externally connected type Upsetting head, and process without Upsetting head PE pipe with standard straight general formula, reduce the manufacture cost of PE pipe, also can recycling after the processing of waste and old PE pipe, economic use, cost-saving, life cycle is long.

Description

The PE pipe of band one Upsetting head

Technical field

The PE pipe that a kind of life cycle of the utility model is long, especially the PE pipe of band one Upsetting head.

Background technique

PE pipe is plumbing conveyance conduit conventional in life, without Upsetting head PE pipe because of leak explosion frequency high, basic eliminating uses, PE pipe conventional is at present generally whole the overcoat Upsetting head without dimensional changes, in process of deployment, connect with Kraft between PE pipe, or Upsetting head is welded on the end of PE pipe, add Flange joint again, but, in use, due to pressure excessive time weld easily come off or burst, cannot normally use, simultaneously, it is also a kind of waste that the conventional PE pipe retained and the PE pipe changed cannot use, cause loss economically.

Model utility content

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, the band one Upsetting PE pipe of head is provided, the PE pipe of routine is generated in end by hot melting way the Upsetting head of protruding one, at a PE pipe outer suit loose flange, additional sealing gasket between the Upsetting head junction surface of then two PE pipes, connect with fastening nuts in the mounting hole penetrating loose flange with fastening screw, the conventional PE pipe of former retention can be utilized, also can the PE pipe processing recycling changed, Upsetting head and PE pipe are integrated, solve in use due to pressure excessive time weld come off or burst, and cause normally using.

For achieving the above object, the technical solution of the utility model is: the PE pipe of band one Upsetting head, comprise tubing and loose flange, described tubing head end establishes Upsetting head, and described Upsetting head is protruding step, and exterior edge face is junction surface, described junction surface is communicated with endoporus, described loose flange is sleeved on the outer wall of tubing, above establishes some mounting holes, and described mounting hole is through hole.

Further setting, the Upsetting head that described tubing and head end are established is integrated shape.

Further setting, to be through state process without the tubing hot melt of Upsetting head described Upsetting head.

Further setting, described loose flange endoporus is greater than the external diameter of tubing.

The beneficial effects of the utility model are: the Upsetting head being generated protruding one on the PE pipe of routine by hot melting way in end, at a PE pipe outer suit loose flange, additional sealing gasket between the Upsetting head junction surface of then two PE pipes, connect with fastening nuts in the mounting hole penetrating loose flange with fastening screw, the conventional PE pipe of former retention can be utilized, also can the PE pipe processing recycling changed, Upsetting head and PE pipe are integrated, solve in use due to pressure excessive time weld come off or burst, and cause normally using.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the right elevation of Fig. 1.

In figure: tubing 1, Upsetting 101, junction surface 102, endoporus 103, loose flange 2, mounting hole 201.

Embodiment

Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.

As shown in Fig. 1 ~ Fig. 2, the PE pipe of band one Upsetting head, comprise tubing 1 and loose flange 2, described tubing 1 head end establishes Upsetting 101, described Upsetting 101 is protruding step, exterior edge face is junction surface 102, described junction surface 102 is communicated with endoporus 103, described loose flange 2 is sleeved on the outer wall of tubing 1, on establish some mounting holes 201, described mounting hole 201 is through hole, the utility model generates the Upsetting head of protruding one on the PE pipe of routine in end by hot melting way, at a PE pipe outer suit loose flange 2, additional sealing gasket between Upsetting 101 junction surfaces of then two PE pipes, connect with fastening nuts in the mounting hole 201 penetrating loose flange 2 with fastening screw, the conventional PE pipe of former retention can be utilized, also can the PE pipe processing recycling changed, Upsetting 101 and PE pipe are integrated, solve in use due to pressure excessive time weld come off or burst, and cause normally using.

The Upsetting that establishes of described tubing 1 and head end 101 is integrated shape.

To be through state process without tubing 1 hot melt of Upsetting 101 described Upsetting 101.

Described loose flange 2 endoporus is greater than the external diameter of tubing 1.

Upsetting 101 adds man-hour, platform fixes PE pipe, heat to PE pipe with the flame that oxygen and acetylene produce, extrude under slow pressure, block puts in place and uses jack compacting, rear water cooling, remove mold forming again, one be successful after, be inserted in loose flange 2, with the other end of same way processing PE pipe.

More than show and describe basic principle of the present utility model and major character, and advantage of the present utility model.The technician of the industry also understands; the utility model is not by the restriction of above-mentioned case study on implementation; what describe in above-mentioned case study on implementation and specification just illustrates principle of the present utility model; do not departing under the utility model design category prerequisite; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appended claims and equivalent thereof.
