Abstract
The utility model provides an inner-threaded union with a 90-degree bend. The inner-threaded union with the 90-degree bend comprises a union nut, inner threads A are arranged on the inner wall of the union nut, a baffle ring is arranged at one end of the union nut, a straight connector is inserted in the baffle ring, a check ring is arranged at one end of the straight connector, and the check ring and the baffle ring contact. The inner-threaded union with the 90-degree bend is characterized in that the 90-degree bend is arranged at the other end of the union nut, outer threads are arranged at one end of the 90-degree bend, the outer threads are connected with the inner threads A of the union nut, inner threads B are arranged at the other end of the 90-degree bend, and the inner threads B are connected with a pipeline. The straight connector penetrates through the union nut, the check ring is blocked on the baffle ring of the union nut, then the end of the 90-degree bend with the outer threads and the inner threads A of the union nut are screwed tightly, the end face of the 90-degree bend is arranged on the end face of the straight connector in squeezed mode to prevent the straight connector from rotating, and when the angle of a pipe fitting needs to be changed on the same plane, only is the tightness of the union nut and the 90-degree bend needs to be adjusted, and the angle can be adjusted quickly without dismounting the whole pipe fitting.
Description
Technical field
The utility model relates to union, particularly relates to the internal thread elbow with 90-degree angle union, belongs to the plastic pipe field.
Background technique
Threaded for union refers to threaded pipe joint, is modal a kind of pipe fitting in industry and the life, and threaded for union makes the connection of pipeline become simpler, and dismounting and change is also easier, has greatly saved the cost that pipeline connects.Existing union can only connect two two pipelines on the same straight line, and to carry out 90 ° of connections to pipeline, will be with 90 ° of connecting tubes, but in some special occasions, such as narrow and small underground job space, the job site of duration anxiety, with common 90 ° of connecting tubes install, dismounting speed is slow, and can't regulate two pipelines angle in one plane, thereby reduce pipe fitting connection construction efficient.
Summary of the invention
The purpose of this utility model is the shortcoming that exists in order to overcome prior art, and a kind of angle that changes arbitrarily pipe fitting at same plane is provided, and pipe fitting is installed, dismounting is quick and convenient, simple in structure, the internal thread elbow with 90-degree angle union that connection sealing is good.
The technological scheme of the utility model internal thread elbow with 90-degree angle union is: comprise union nut, the union nut inwall is shaped with the internal thread first, one of union nut is shaped with baffle ring, insert straight connector in the baffle ring, be shaped with back-up ring one of straight connector, back-up ring contacts with baffle ring, it is characterized in that 90 ° of elbows of described union nut other end installation, one of 90 ° of elbows is shaped with outside thread, outside thread is connected with the internal thread first of union nut, be shaped with internal thread second in the other end of 90 ° of elbows, internal thread second connecting tube.
The utility model discloses a kind of internal thread elbow with 90-degree angle union, union nut is passed in straight connector, the back-up ring of straight connector is stuck on the baffle ring of union nut, then 90 ° of elbows being shaped with an externally threaded internal thread with union nut screws, the end face of 90 ° of elbows is squeezed on the end face of straight connector, avoid straight connector to produce rotation, when will be when same plane changes arbitrarily the angle of pipe fitting, as long as the degree of tightness of regulating a little union nut and 90 ° of elbows, just rapid adjusting angle, need not to disassemble whole, in addition, this internal thread elbow with 90-degree angle union Applicable scope is extensive, is fit to the operation of small space scope, has realized the quick connection of pipe fitting.
The union of the utility model internal thread elbow with 90-degree angle, the externally threaded end surface of described 90 ° of elbow systems is shaped with seal groove, and seal ring is installed in seal groove, and seal ring contacts with the upper-end surface of straight connector.Seal ring has been arranged, made the contacting point sealing of 90 ° of elbows and straight connector reliable, can prevent because the leaking of not tightly causing of twisting of union nut.The other end of described straight connector is female adapter or male connection.Connect in order to satisfy dissimilar pipe fitting, versatility is good.
Description of drawings
Fig. 1 is that the straight connector of internal thread elbow with 90-degree angle union is the structural representation of female adapter;
Fig. 2 is that the straight connector of internal thread elbow with 90-degree angle union is the structural representation of male connection.
Embodiment
The utility model relates to a kind of internal thread elbow with 90-degree angle union, such as Fig. 1-shown in Figure 2, comprise union nut 1, the union nut inwall is shaped with internal thread first 11, one of union nut is shaped with baffle ring 12, insert straight connector 2 in the baffle ring, be shaped with back-up ring 21 one of straight connector, back-up ring contacts with baffle ring, one that it is characterized in that 3,90 ° of elbows of described union nut 1 other end 90 ° of elbows of installation is shaped with outside thread 31, and outside thread is connected with the internal thread first 11 of union nut 1, be shaped with internal thread second 32 in the other end of 90 ° of elbows 3, internal thread second connecting tube.Union nut 1 is passed in straight connector 2, the back-up ring 21 of straight connector 2 is stuck on the baffle ring 12 of union nut 1, then an internal thread with union nut 1 that 90 ° of elbows 3 is shaped with outside thread 31 screws, the end face of 90 ° of elbows is squeezed on the end face of straight connector 2, avoid straight connector to produce rotation, when will be when same plane changes arbitrarily the angle of pipe fitting, as long as the degree of tightness of regulating a little union nut 1 and 90 ° of elbows 3, just rapid adjusting angle, need not to disassemble whole, in addition, this internal thread elbow with 90-degree angle union Applicable scope is extensive, be fit to the operation of small space scope, realized the quick connection of pipe fitting.One end surface of described 90 ° of elbows, 3 outside threads 31 processed is shaped with seal groove 33, and seal ring 4 is installed in seal groove, and seal ring contacts with the upper-end surface of straight connector 2.Seal ring 4 has been arranged, made 90 ° of elbows 3 reliable with the contacting point sealing of straight connector 2, can prevent because the leaking of not tightly causing of twisting of union nut 1.The other end of described straight connector 2 is female adapter 22 or male connection 23.Connect in order to satisfy dissimilar pipe fitting, versatility is good.
