Abstract

The utility model provides a pipe fitting for internal heating. The pipe fitting integrates a sealing joint and a fitting, and comprises a fitting body, wherein the fitting body is provided with an output port, and the inner wall of the output port is provided with screw threads which are cylindrical screw threads or conical threads. The fitting body further comprises the sealing joint matched with the threads of the output port. The fitting body is provided with the output port used for leading in a heating band, and is simple in structure, and extra fittings are not needed.

Description

Heating pipe fittings in a kind of
Technical field
The utility model belongs to pipe fittings field.
Background technique
Cold winter, in outdoor fluid pipeline, usually can occur freezing, prior art is to be enclosed with heating tape and thermal insulating material at the outer surface of liquid (tap water or former wet goods) pipeline, there is following shortcoming in this structure of thermal insulating material: the indivedual local breakages of thermal insulating material or the area for threshold state, cold makes certain part in pipeline occur freezing, often be difficult for finding freezing place, delay use, and while needing Maintenance and Repair, outermost thermal insulating material must accurately excavate and dismantle, it is very inconvenient to operate, and waste thermal insulating material, and to the pipeline using, can not exempt to dig and install or maintenance.
In order to realize at pipeline interior heating, need on pipeline, arrange heating wire is caused to the entrance in pipeline, conventionally can on pipeline, increase a three-way pipe and realize, troublesome poeration, increases cost.And this mode, heating tape will, away from stop valve, affect heating effect.
Model utility content
The utility model is the problem solving in background technique, and a kind of interior heating pipe fittings that integrates SEALING FITTING and accessory is provided.
Technical solution of the present utility model is:
Heating pipe fittings in a kind of, comprises accessory body, and its special way is: on described accessory body, be provided with output interface, on output interface inwall, be provided with screw thread.
Above-mentioned screw thread is cylindrical screw thread.
Or above-mentioned screw thread is conical screw thread.
Above-mentioned accessory body also comprises SEALING FITTING, described SEALING FITTING and output interface screwed connection.
Above-mentioned accessory body is stop valve or bipass or three-way pipe or bend pipe.
Above-mentioned SEALING FITTING is one or two.
The central axis of above-mentioned SEALING FITTING is vertical with the central axis of pipeline.
The central axis angle of the central axis of above-mentioned SEALING FITTING and pipeline is 5 °~45 °.
Or above-mentioned SEALING FITTING is cable clip tightening seal joint.
Above-mentioned SEALING FITTING is cable clip tightening seal joint.
The utility model has the advantages that:
(1) on accessory body, be provided with output interface, for introducing SEALING FITTING.
(2) the central axis angle of the central axis of SEALING FITTING and pipeline is 5 °~45 °, the introducing of the heating wire of being more convenient for, the resistance while reducing to introduce heating wire.
Accompanying drawing explanation
Fig. 1 is provided with vertical seal joint on stop valve;
Fig. 2 is provided with inclination SEALING FITTING on stop valve;
Fig. 3 is provided with vertical seal joint on bipass;
Fig. 4 is provided with inclination SEALING FITTING on bipass;
Fig. 5 is conical screw thread structural representation;
Fig. 6 is cylindrical wire buckle structure schematic diagram.
Wherein: 1-SEALING FITTING; 2-stop valve; 3-bipass; 4-output interface; 5-screw thread.
Embodiment
Heating pipe fittings in a kind of, comprises accessory body, is provided with output interface 4 on accessory body, is provided with screw thread 5 on output interface inwall.
Screw thread is conical screw thread, as Fig. 5.
Screw thread is cylindrical screw thread, as Fig. 6.
Accessory body also comprises SEALING FITTING 1, SEALING FITTING and output interface screwed connection.SEALING FITTING is one or two.
Accessory body is stop valve 2, as Fig. 1; Or bipass 3, as Fig. 3, or three-way pipe or bend pipe.
The central axis of SEALING FITTING is vertical with the central axis of pipeline, as Fig. 1 and Fig. 3.
The central axis angle of the central axis of SEALING FITTING and pipeline is 5 °~45 °, as Fig. 2 and Fig. 4, the introducing of the heating wire of being more convenient for is set like this, reduces resistance.
SEALING FITTING can be selected conventional cable clip tightening seal joint, and as the DQM of Yueqing City Yi Kesi Electric Applicance Co., Ltd series cable clip tightening seal joint, material is high-quality steel or stainless steel or engineering plastics or aluminum alloy, mechanical type cable clip tightening seal joint.
