Description

A kind of novel heating and ventilating pipeline

Technical field

The utility model is related to HVAC fields, and in particular to a kind of novel heating and ventilating pipeline.

Background technology

Heating and ventilating pipeline refers to the pipeline for being passed through high temperature liquid or gas in HVAC industry.For relatively long distance For heating and ventilating pipeline, generally docked by pipelines more than two sections or both ends.For the mode of pipeline connection, there is fast quick access The modes such as head connection, threaded connection, flange welding.Wherein, for the stainless steel heating and ventilating pipeline of threaded connection, due to being rigid Property connection, and in heating and ventilating pipeline medium temperature change it is bigger, therefore after long-play, threaded connection place is due to heat expansion The case where thread pitch caused by shrinkage becomes larger, leak is dripped is commonplace.

Utility model content

In view of the above-mentioned problems, the utility model provides a kind of novel heating and ventilating pipeline.

The purpose of this utility model is realized using following technical scheme：

The front end of a kind of novel heating and ventilating pipeline, including first pipe and second pipe, first pipe passes through thread head and The internal threads of two pipelines is threadedly coupled, and first pipe is affixed by the first insulation ring and thread head, thread head include internal perisporium with Periphery wall, it is affixed by multiple heat-insulated pillars between internal perisporium and periphery wall, be connected in the front-end surface of internal perisporium second every Gas ket is filled with heat-barrier material between internal perisporium and periphery wall；Pass through between thread barrel where second pipe and internal thread Three insulation rings are affixed, and when thread head is screwed on completely with thread barrel, third insulation ring is overlapped with the horizontal position of the second spacer ring.

Description of the drawings

Using attached drawing, the utility model is described in further detail, but the embodiment in attached drawing is not constituted to the utility model Any restrictions for those of ordinary skill in the art without creative efforts, can also be according to following attached Figure obtains other attached drawings.

Fig. 1 is the sectional view of first pipe；

Fig. 2 is the axonometric drawing of first pipe；

Fig. 3 is the axonometric drawing of second pipe；

Fig. 4 is the axonometric drawing of heat-insulated pillar；

Sectional view after Fig. 5 is first pipe and second pipe is screwed in place completely.

Specific implementation mode

The utility model is further described with the following Examples.

A kind of novel heating and ventilating pipeline as shown in Figs. 1-5, including first pipe 1 and second pipe 2, before first pipe 1 End is threadedly coupled by thread head 10 with the internal thread 3 of second pipe 2, and first pipe 1 is solid by the first insulation ring 4 and thread head It connects, thread head 10 includes internal perisporium 5 and periphery wall 6, affixed by multiple heat-insulated pillars 7 between internal perisporium 5 and periphery wall 6, interior It is connected with the second insulation ring 8 in the front-end surface of peripheral wall 5, heat-barrier material 9 is filled between internal perisporium 5 and periphery wall 6.Second pipe It is affixed by third insulation ring 13 between thread barrel 12 where road 2 and internal thread 3, when thread head 10 and thread barrel 12 revolve completely When connecing, third insulation ring 13 is overlapped with the horizontal position of the second spacer ring 8.

The side of scheme as a further preference, the periphery wall 6 has external screw thread 11.

The front end of scheme as a further preference, periphery wall 6 mortgages on the medial surface of the second insulation ring 8.

Scheme as a further preference, the first pipe 1 and second pipe 2 are stainless steel pipes, the thread head 10 and thread barrel 12 be made of stainless steel.

Scheme as a further preference, first insulation ring 4, the second insulation ring 8 and heat-insulated pillar 7 are poly- by foaming Urethane is made.

Scheme as a further preference, the heat-barrier material 9 are asbestos.

First pipe 1 and second pipe 2 all merely illustrate a portion.

The heating and ventilating pipeline is in use, first pipe 1 and 2 screw thread of second pipe are screwed on, on the one hand the first insulation ring 4 The heat conduction isolation of first pipe 1 and periphery wall 6 is come, another aspect heat-barrier material 9, heat-insulated pillar 7 by internal perisporium 5 with Heat conduction isolation between periphery wall 6 is come, and the second insulation ring 8 passes the direct heat of periphery wall 6 and pipeline internal medium Isolation is led to come, such periphery wall 6 by heat influenced very little, greatly reduce due to external screw thread 11 caused by expanding with heat and contract with cold Deformation；Thread barrel 12 is due to the presence of third insulation ring 13 and the second insulation ring 8, thread barrel 12 and pipeline internal medium, the second pipe Heat conduction between road 2, which is also isolated, comes, therefore internal thread 3 is also very small due to being deformed caused by expanding with heat and contract with cold.

The internal thread of the heating and ventilating pipeline, external screw thread cooperation influenced by the heat that pipeline internal medium is brought it is all small, can be very The deformation for reducing to big degree screw-thread fit, reduces water clock, and compact-sized, achieves good effect in actual use.

Finally it should be noted that above example is only to illustrate the technical solution of the utility model, rather than to this reality With the limitation of novel protected range, although being explained in detail to the utility model with reference to preferred embodiment, this field it is general Lead to it will be appreciated by the skilled person that can be modified or replaced equivalently to the technical solution of the utility model, without departing from this The spirit and scope of utility model technical solution.
