The present invention relates to a pipe material connector, in the joint connection of various pipe materials, by the easy and flexible connection construction according to the site conditions without any additional fusion welding work, the operator can reduce the work maneuver while working It relates to a pipe fitting end which is convenient and provides excellent workability and economy.

In general, piping materials are largely divided into galvanized pipes, non-ferrous metal pipes, and concrete pipes formed by supplementing the disadvantages of corrosion of ferrous metals. Such ferrous metal pipes or non-ferrous metal pipes are expensive to manufacture and easily corroded after installation. It was uneconomical for the equipment, and ineffective for the aftercare.

Recently, synthetic resin pipes developed and developed in the petrochemical industry are mainly used for water pipes, drinking water and sewage pipes, which are drinking water pipes for homes and factories, as well as industrial piping materials such as highly poisonous fluids. In particular, plastic piping materials, which are made of polyethylene, polyvinyl chloride, polypropylene, and the like, are widely used in various industrial fields described above.

This pipe material is as important as the material and shape, and the work of connecting each other in the basic piping work of long-distance flow paths or large buildings is a very important element. In most cases, the flange is fused to one end and fixed with a fastener in the field, or a large length of pipe material that is pre-welded is constructed as a graph.

Looking at the method of connecting such a conventional synthetic resin piping material as follows.

First, the connection method by the electronic fusion sheet (Electronic fusion sheet), as shown in Figure 4, horizontally align the piping material (10, 10a) and remove the foreign substances at the joint portion of the electric wire 21 is integrated electric fusion The connection part is wound with the connection pipe 20 and the end is fixed. The heat is supplied to the heating wire 21 of the fixed fusion connection tube 20 in this way to generate heat from the heating wire 21 and by this heat the inner surface of the fusion connection tube 20 and the outer surface of the piping material (10, 10a) Melting while fusion is bonded to the abutment pipe material (10, 10a).

However, since the electric fusion sheet method has to use electricity, it is difficult to use in an area where electricity supply is not desired, and a problem in which leakage occurs due to weak welding force on the overlapping portion of the fusion connection pipe 20 is overlapped. There was. In addition, the electrofusion sheet method is difficult in the rainy construction work, the construction of connecting a plurality of piping materials (10, 10a) is difficult to simultaneously construction, the construction period is long, there is a problem that the work process is complicated and economic efficiency is reduced.

On the other hand, as shown in Figure 5, the socket band joining method also aligns the piping material (10, 10a) horizontally and remove the foreign matter at the joint, then wound the heat shrink sheet 30 and the heat shrink sheet 30 using a torch lamp The ends of the end are heated and attached so that both ends are pushed out. After the heating, the heat shrink sheet 30 is wrapped in a stainless band 40 so that the angles 41 are disposed to face each other, and the angles 41 are reinforcement 42. When supported by the bolt 43 and the nut 44 is fixed to the piping material (10, 10a) is connected.

However, such a coupling method requires not only heat providing means such as a torch lamp to connect the piping material 10 and the other piping material 10a, but also a pipe connection in a fire hazard area and a gas leakage area of the torch lamp. Of course, there are many problems, such as a decrease in productivity due to two or more labor hours.

The present invention is coupled to the stopper inside the body, the inclined surface is formed so that the inner diameter becomes narrower from the front to the rear so as to be combined with the stopper, while the plurality of fixing holes are coupled to the other flange on the surface between the inner diameter and the outer peripheral surface A flange formed at equal intervals along the circumferential direction; A stopper that is coupled to the inner diameter of the flange by interference fit, the outer surface of which is inclined narrower from the front to the rear, and a plurality of locking protrusions are formed on the through-wall wall through which the pipe member penetrates to be supported and fixed to the outer diameter of the pipe member; The object is achieved by a pipe fitting coupler, which is formed between a pipe member and a connecting portion of another pipe member to form a packing for completely sealing the connection seam.

Next will be described in more detail the present invention in accordance with the accompanying drawings.

First, as shown in Figure 1, the subject innovation is the inner body is coupled to the stopper 200, the inclined surface 120 is narrower from the front side to the rear so that the stopper 200 and the interference fit coupled to the front On the other hand, on the surface between the inner diameter 130 and the outer circumferential surface, a plurality of fixing holes 110 are formed at equal intervals along the circumferential direction so as to be coupled to the other flange, and the inner diameter 130 of the flange 100. While coupled to the interference fit, the outer diameter 230 is formed to become narrower from the front to the rear, while a plurality of locking projections 210 are formed on the outer wall of the through hole 220 through which the piping material 10 penetrates the piping material 10 ) Is formed between the stopper 200 formed to be supported and fixed to the outer diameter, and the packing 300 is inserted between the connecting portion of the pipe member 10 and the other pipe member 10a to fully seal the connection seam.

At this time, the stopper 210 of the stopper 200 is a plurality of right triangular shape is formed upside down toward the inside of the through hole 220 is protruded, the vertical side forming a right angle is formed to the front side.

At this time, the stopper 200 is formed on the outer circumferential surface side of the incision groove 240 is cut in the longitudinal direction, while the fixing protrusion 211 protruding toward the inner side on the inner wall of the through-hole 220 through which the piping material 10 passes It is formed in the shape of a tetrahedron.

At this time, the packing 300 has a plate-shaped ring-shaped packing surface 320 is formed, the fitting surface 310 to be fitted to the outer diameter of the pipe member 10 on one side of the plate-shaped packing surface 320. Protrudes perpendicular to the packing surface.

Referring to such a configuration in more detail as follows.

First, as shown in Figures 1 to 3, the pipe material 10 is a synthetic resin pipe material in addition to the double wall pipe or triple wall pipe in addition to the multi-wall wall, laminated pipe, sewage sewage pipe, general smooth sewage pipe, respectively. It can be formed and applied, any of which differs in its use and appearance.

The flange 100 initially inserted through the end of the one pipe member 10 is loosely positioned in a free state for a while due to the inner diameter 130 wider than the outer diameter of the pipe member 10.

At this time, the second stopper 200 is inserted through the end of the pipe member 10 has a through-hole 220 is formed in the body, the through-hole 220 has a rectangular triangular projection protrusion 210 projecting toward the inner center. ) Are formed in plurality.

Such a plurality of engaging projections 210 are formed in the reverse direction of the right triangular shape, at this time the perpendicular surface forming a vertical plane is formed on the opposite side that is inserted into the pipe member 10, that is, the front of the body of the stopper 200 when the right triangular shape Easily inserted along the inclined surface, stop the insertion of the stopper in the appropriate position 210 is the end of the pipe member 10, that is, the insertion resistance is received due to the right angled edge portion to the opposite side inserted.

At this time, the first inserted flange 100 is fitted into the inclined outer diameter 230 of the stopper 200 is coupled, which is the stopper 200 and the inner diameter 130, the inclined surface is formed so that the outer diameter 230 is narrowed from the front to the rear The coupling is basically achieved by the surface contact of the inner and outer diameters of the flange 100 in which the inclined surface 120 is formed so as to narrow from the front side to the rear side.

At this time, the end of the pipe member 10 is fitted with a packing 300 through which the inner center of the pipe member 10 has the same size as the inner diameter of the pipe member 10, which is inserted into the pipe member 10 toward one side of the packing surface 320 having a plate-shaped annular shape. The fitting protrusion 310 is fitted to the pipe member 10 by being protruded orthogonal to the packing surface 320 so that the fitting protrusion 310 may be inserted therein.

On the other hand, the above-mentioned stopper 200 is applicable to other embodiments, and forms a predetermined cutting groove 211 in one side of the stopper 200 in the longitudinal direction, that is, the direction inserted from the front to the rear, Instead of the plurality of locking protrusions 210 formed in the inner through hole 220 of the stopper 200, one or more fixing protrusions 211 of the rectangular parallelepiped are formed to protrude toward the inner center of the through hole 220.

 This causes the stopper 200 to be more firmly fixed on the outer circumferential surface of the pipe member 10 due to the protruding fixing protrusion 211 of the stopper 200. In this case, the excessively protruding fixing protrusion 211 is the pipe member 10. The stopper 200 can be easily fitted to the pipe member 10 due to elasticity, such that the cutting groove 240 opens the body to the outside so that the locking jaw 11 can be easily fitted to the preformed locking jaw 11. Is formed.

The stopper 200 is fixedly coupled to the outer peripheral surface of the pipe member so that the fixing protrusion 211 is fixed to the pipe member in advance.

Referring to the embodiment of the present invention according to the configuration as described above are as follows.

As shown in FIGS. 2 to 3, the stopping protrusion 210 or the fixing protrusion 211 of the stopper 200 inserted through an end portion of the one pipe member 10 fixes the stopper 200 and stops the stopper 200. 200) the flange 100 is inserted and coupled to the outside to have a firm fixing force by the friction force by the surface contact.

At this time, the end of the piping material 10 has a predetermined thickness, while the annular plate-shaped packing (300) is fitted to the end of the piping material 10 by the fitting protrusion 310 protruding to one side, wherein the ring The inner through groove of the shaped packing 300 is the same as the inner diameter of the piping material.

When the connector of the one pipe member 10 is completed, the connectors of the other pipe member 10a formed in the same manner are connected to each other and symmetrically connected to each other, and a plurality of fixing holes 110 formed on the flanges 100 on both sides connected to each other. ) Also face each other, and tighten the symmetrical flange 100 by using a fastener 400 such as a bolt and a nut.

This is because the fastener 400 pulls the body of the flange 100 through the fixing hole 110 of the flange 100, and thus the inclined surface 120 and the stopper 200 of the inner diameter 130 of the flange 100. The inclined surface of the outer diameter 230 is tightened with more firm friction toward the end sides of the piping materials 10 and 10a, respectively, wherein the locking projections 210 and the fixing projections 211 of the stopper 200 are both piping materials 10 and 10a. Are attracted to each other.

At this time, the annular packing 300 is inserted between the end portions of the piping materials 10 and 10a, and the piping materials 10 and 10a are tightened toward the packing 300, thereby compressing both ends thereof. Promoting a complete seal, such as to prevent leakage at the source.

The connector having such a coupling structure can be realized in the double wall pipe or triple wall pipe in the same way. In particular, it can easily withstand the pressure resistance and watertightness caused by the undergrounding and the like, and it is easy to construct the pipe connection without the expert piping skills of skilled workers. can do.

In this way, the fitting coupling piping material of the present invention, when connecting the joints of various piping materials, by connecting easily and flexibly according to the site conditions without any pre-welding work, the operator reduces the man-hours, There is an economical effect that the work is convenient and the production cost is reduced together with the excellent workability.
