Abstract
The utility model discloses a pipeline welding structure which comprises a main pipe and a branch pipe. A ring-shaped welding piece is arranged on the lower end of the branch pipe, and the length of the branch pipe below the ring-shaped welding piece is matched with the wall thickness of the main pipe. Welding positions of the ring-shaped welding piece and the main pipe are connected in a sealed mode, and the lower end of the branch pipe is in welded connection with the main pipe through hot melting. According to the designed novel pipeline welding structure, the ring-shaped welding piece is arranged on the periphery of the branch pipe in a surrounded mode, the ring-shaped welding piece is participated into hot melting connection in construction so that waste of existing three-way connection is avoided, the technical defects in an existing adapting form hot melting connection is overcome, the technology requirements for pressure resistance property can be met by a system, and positive practical significance is achieved.
Description
Technical field
The utility model relates to a kind of pipeline welding structure.
Background technique
In recent years, plastic pipe is applied in the productive life more and more.For the supervisor of plastic pipe and the connection between the arm, current threeway connection, two kinds of linkage structures of socket hot-melting welding of mainly containing.
Three-way connection structure is present the most general technology, and it is the connection that utilizes between threeway realization supervisor and the arm, shown in accompanying drawing 1; This Placement needs first cutting supervisor 1 in application process, and then is connected with threeway 5 thermofussion weldings, and its hot melt junction surface 4 is on the tube wall of pipeline.One has caused the waste of supervisor's leftover pieces, and two come each three port to need the twice welding process, have increased greatly construction cost (such as artificial, equipment, power cost etc.).
The socket hot-melting welding manner is mainly used on the little exposed installation pipeline of operating pressure at present, and the method is specifically referring to shown in Fig. 2 ~ 3, and its hot melt junction surface 4 is supervisor 1 tube wall and the bottom sides of arm 2.Compare three-way connection structure, this Placement can avoid being responsible for cutting and welding in construction, but having relatively high expectations for bore size, welding technique in the practice of construction process, occur easily that boring is excessive to cause closely interlock of socket weld, welding technique is not in place to cause the problem such as system's bearing capacity deficiency.
Summary of the invention
The purpose of this utility model provides a kind of pipeline welding structure.
To achieve the above object of the invention, the technical solution adopted in the utility model is: a kind of pipeline welding structure, comprise supervisor and arm, and the lower end of described arm is provided with annular weldment, and the length of the arm of annular weldment below cooperates with supervisor's wall thickness; Described annular weldment and supervisor's weld is tightly connected; The lower end of arm is connected by sweat soldering with supervisor.
Above, the length of the arm of described annular weldment below cooperates with supervisor's wall thickness, and is preferred, and the length of the arm of annular weldment below is identical with supervisor's wall thickness, stretches into long and the fluid flow impact supervisor to avoid arm.
Described annular weldment and supervisor's weld is tightly connected, and namely the shape of annular weldment matches with the shape of supervisor's weld, and namely the bending amplitude of annular weldment is consistent with supervisor's outer surface.
The utility model arm periphery is around establishing annular weldment, namely one enclose shape of a saddle weldment, and in construction, participate in together the hot melt connection, thus the waste of both having avoided existing threeway to connect, can remedy again the technological deficiency of existing spigot and socket type sweat soldering, the system resistance to pressure of making satisfies technological requirement.
In the technique scheme, the width of described annular weldment is 1/3 ~ 1/2 of arm diameter.The width of annular weldment can be adjusted according to working pressure, and its material must not be lower than the tubing material of arm.
In the technique scheme, described annular weldment and arm are structure as a whole.
Because technique scheme is used, the utility model compared with prior art has following advantages:
1. the utility model design has obtained a kind of new pipeline welding structure, be peripherally installed with an annular weldment at arm, in construction, should participate in together the hot melt connection by the annular weldment, thereby the waste of having avoided existing threeway to connect, can remedy again the technological deficiency of existing spigot and socket type sweat soldering, the system resistance to pressure of making satisfies technological requirement, has obtained positive realistic meaning.
2. pipeline welding structure of the present utility model can be applied to condensate correcting-distribuing device, facts have proved, adopts this linkage structure greatly to increase work efficiency, and can reduce the scrap waste residue, avoids supervisor's waste, can satisfy the green construction requirement.
3. of the present utility model simple in structure, be easy to preparation, have fabulous applicability, be suitable for applying.

Embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment one
Shown in Fig. 4 ~ 5, a kind of pipeline welding structure comprises supervisor 1 and arm 2, and the lower end of described arm is provided with annular weldment 3, and the length of the arm of annular weldment below cooperates with supervisor's wall thickness; Described annular weldment and supervisor's weld is tightly connected; The lower end of arm is connected by sweat soldering with supervisor.Its hot melt junction surface 4 is referring to shown in Figure 5.
The width of described annular weldment is 30mm, and the arm diameter is 63mm.Described annular weldment and arm are structure as a whole.
The utility model in the arm periphery around a ring shape weldment (shape of a saddle weldment) is set, and in construction, participate in together hot melt and connect, both can avoid the waste of threeway connection, and also can remedy the technological deficiency of spigot and socket type sweat soldering, the system resistance to pressure of making satisfies technological requirement.
The constituent element of described annular weldment (shape of a saddle weldment) is to increase the circle bending amplitude shape of a saddle annex consistent with subjective outer surface in the arm outer.Pipeline and annex form by professional Mold Making as a weldment integral body.The similar horn shape of the shape of a saddle, its purposes are to substitute threeway as the primary branch link.On making, shape of a saddle weldment inserts supervisor's partial-length should be consistent with wall thickness, avoids stretching into long impact supervisor fluid flow; Shape of a saddle annex width can be according to the working pressure adjustment; The weldment material must not be lower than the tubing material.
On benefit, adopt linkage structure of the present utility model can improve operator's efficiency; Improve job site civilized construction level, reduced the waste residue scrap, avoid supervisor's waste, improve construction environment; Meet save land, energy-conservation, material-saving and environmental requirement, can satisfy the green construction requirement; Increase on-the-spot serious forgiveness and maintenance activities, saved the expenses such as transportation of materials.
