Abstract

The utility model relates to a pipe fitting connecting structure, which is characterized in that the utility model adopts a special connecter which is called as an inner plug body. At least one annular groove and a containing space are arranged on the inner plug body. A plurality of through holes are arranged at the connecting point of the inner plug body by a connecting pipe fitting. The inner plug body is arranged in the connecting point of the pipe fitting. An inner annular flange is arranged at the position which is on the pipe fitting and is opposite to the annular groove of the inner plug body, which leads the inner annular flange of the pipe fitting to be embedded in the inner annular groove of the inner plug body. After two pipe fittings are arranged in the inner plug body at the connecting point and connected, a combined coating body is integrally formed on the connecting point. The utility model abolishes the welding technology of pipe fittings, so the assembly and the connection of the pipe fittings can not deform, with the advantages of higher manufacturing quality and economic benefits.

Description

The pipe fitting joint construction

The utility model belongs to the engineering component, is specifically related to a kind of pipe fitting joint structure.

It is general as Fig. 8, shown in Figure 9 that two pipe fittings intersects connecting structure, ties up on the connecting end of side pipe spare a and be cut into a kerf a1 earlier, in the outside that side pipe spare a is leaned against person in charge's part b joint, welds afterwards then again.The third not parallel pipe fitting a that overlaps and for example shown in Figure 10, though it need not offer notch, but because after the welding, the intensity of part can reduce around weld, if under intensity quality requirements conditions of higher, then after welding assembly is finished, must heat-treat again usually, make weld and host material (being responsible for part and side pipe spare) reach the strength of materials than homogeneous.Yet, because of assembling after finishing framework or partly the volume of spare part is bigger, and shape and structure is also complicated, when it is heat-treated, the pipe fitting that then is not easy each is formed reaches the temperature of heating synchronously and equably, or lowers the temperature synchronously, makes that heat treated rate of warming of control and cooling rate are very difficult, therefore change expense expense in heat treatment is higher, and is not easy the thermal effectiveness that reaches desirable; And complex component is more difficult than simple member during heat treatment, so the heat treatment expense of complex component is higher, increases manufacture cost in rain.Moreover because the pipe fitting group volume that assembling is finished is bigger, the necessary bigger heat treatment furnace of use capacity has also promptly reduced the heat treatment amount that heat treatment furnace carries out at every turn, and yielding capacity is reduced.Again because of, distortion generally is difficult to avoid when the welding assembly pipe fitting, and can produce secondary deformation again after heat-treating.So traditional pipe fitting is welded to connect method, generally all to influence the boundary dimension of pipe fitting builtup member.

The purpose of this utility model provides a kind of pipe fitting joint construction, makes the connection between pipe fitting, particularly connect two intersect pipe fitting the time, can connect without welding manner, thereby can avoid the malformation of pipe fitting builtup member.

For achieving the above object, the utility model has adopted a hollow pipe fitting special use and has been called the special link of inner plug body, is provided with a ring groove and a containing space on this inner plug body at least; And this hollow pipe fitting is provided with several perforation in its joint; This inner plug body is inserted the joint in the hollow pipe fitting, and the ring groove place with respect to inner plug body is arranged to ring flange on hollow pipe fitting, and the interior ring flange of hollow pipe fitting can be embedded in the ring groove of inner plug body; When two hollow pipe fittings are connected, insert inner plug body respectively, and make one of them hollow pipe fitting lean against the joint of another hollow tubular in two hollow pipe fitting joints, and on this joint integrally formed one linked two hollow tubulars in conjunction with covering material.

Requirement according to various pipe fittings connections, above-mentioned inner plug body can have different physique structures, as can be a L shaped body, cross body, three-dimensional rectangular coordinates body or nonopiate body, and, no matter which kind of physique structure, it is equipped with ring groove on each end, and is formed with containing space between each ring groove.

Advantage of the present utility model has: because the little and simple shape of hollow pipe fitting volume before not making up, therefore can heat-treat it in advance, and it is easier to control heat treatment temperature when heat-treating, and improves the heat treatment quality easily, reduces the heat treatment cost; Also because the hollow pipe fitting system of assembling connection is earlier heat treated, so the utility model assembling can not produce distortion when connecting, thereby behind the utility model, the assembling of pipe fitting connection has higher workmanship.

For making the utility model disclose clear and definite more full and accurately, details are as follows to cooperate following drawings and Examples now.
