Abstract
The utility model provides a kind of elbow, and comprise bend pipe, interior connecting head, outer connecting head, strengthen chamber, seal ring, the diameter of bend pipe inside is all identical, and interior connecting head is arranged on the internal diameter of one end of bend pipe, and outer connecting head is arranged on the external diameter of the bend pipe the other end.Strengthen the turning that chamber is arranged on bend pipe outside.Seal ring is arranged on interior connecting head, outer connecting head.Bend pipe inside diameter of the present utility model is identical, ensure that liquid can not make tube fluid pressure increase suddenly when circulating.Interior connecting head is arranged on the internal diameter of bend pipe, and outer connecting head is arranged on the external diameter of bend pipe, makes the connection bore of interior connecting head be less than the connection bore of outer connecting head, thus achieves the pipeline connecting different tube diameters.If break in the turning of bend pipe, strengthening chamber as tube wall for subsequent use, can ensure that liquid circulates smoothly, seepage can not occur.
Description
Technical field
The utility model relates to technical field of pipeline connection, especially a kind of elbow.
Background technique
In prior art, elbow usually arranges plastic whorl pipeline section and is used for connecting other pipe fitting.When connecting the pipeline of different tube diameters, make the caliber of two connecting ends different by the changeover portion in the middle part of reducing bend.But make tube fluid pressure increase suddenly like this, cause the long-term pressurized of reducing bend, working life shortens.In addition, usually need on screw thread, to be wound around the sealing material such as raw meal belt or the rope made of hemp to strengthen the sealing effect of connection when connecting, but when spinning installation, sealing material usually can loosen even to deviate from, and adds the difficulty of installation, also makes its sealing effect greatly reduce.
Summary of the invention
The purpose of this utility model is to provide a kind of elbow, ensure that liquid can not make tube fluid pressure increase suddenly when circulating, ensureing sealing when connecting, possess temporary protection function simultaneously when elbow breaks.
In order to achieve the above object, the utility model provides following technological scheme:
A kind of elbow, comprise bend pipe, interior connecting head, outer connecting head, the diameter of bend pipe inside is all identical, and interior connecting head is arranged on the internal diameter of one end of bend pipe, and outer connecting head is arranged on the external diameter of the bend pipe the other end.Because the inside diameter of bend pipe is identical, ensure that liquid can not make tube fluid pressure increase suddenly when circulating, improving the working life of elbow.Meanwhile, the internal diameter of bend pipe must be less than external diameter, so the port diameter of connecting head must be less than the port diameter of the outer connecting head be connected with external diameter in being connected with internal diameter, thus realizes connecting different calibers.
Further, also comprise and strengthen chamber, strengthen the turning that chamber is arranged on bend pipe outside.Turning due to elbow is easily subject to the shock of foreign material in liquid, thus breaks.When cracking occurs, outside reinforcement chamber forms new elbow outer wall, plays a protective role, and ensures that liquid can not leak.
Further, also comprise seal ring, seal ring is arranged on interior connecting head, outer connecting head.Seal ring is not easy to come off, and improves the sealing effect that elbow connects.
Further, interior connecting head, outer connecting head all arrange screw thread.Be threaded connection external pipe, connect and keep in repair more convenient.
Further, the material of interior connecting head, outer connecting head adopts stainless steel or carbon steel.Adopt the interior connecting head of metallic material and outer connecting head to be not easy to wear and tear, connect tightr.
Beneficial effect of the present utility model is:
1) adopt interior connecting head and outer connecting head, achieve the pipeline connecting different tube diameters;
2) strengthen the intensity that chamber is used for bend pipe turning, meanwhile, if break in the turning of bend pipe, strengthening chamber as tube wall for subsequent use, can also ensure that liquid circulates smoothly, seepage can not occur;
3) interior connecting head, outer connecting head arrange seal ring, improve the sealing that elbow connects;
4) interior connecting head, outer connecting head adopt stainless steel or carbon steel, are not easy wearing and tearing, connect tightr.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is sectional view of the present utility model;
Fig. 3 is using state figure of the present utility model;
In figure, 1, interior connecting head, 2, bend pipe, 3, strengthen chamber, 4, outer connecting head, 5, seal ring.
Embodiment
Below in conjunction with accompanying drawing of the present utility model, be clearly and completely described the technical solution of the utility model, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Shown in Fig. 1-2, a kind of elbow, comprise bend pipe 2, interior connecting head 1, outer connecting head 4, strengthen chamber 3, seal ring 5, the diameter of bend pipe 2 inside is all identical, interior connecting head 1 is arranged on the internal diameter of one end of bend pipe 2, and outer connecting head 4 is arranged on the external diameter of bend pipe 2 the other end.Interior connecting head 1, outer connecting head 4 all arrange screw thread.The material of interior connecting head 1, outer connecting head 4 adopts A105,304L or 316L, makes it be not easy wearing and tearing
Because the inside diameter of bend pipe is identical, ensure that liquid can not make tube fluid pressure increase suddenly when circulating.Interior connecting head 1 is arranged on the internal diameter of bend pipe, and outer connecting head 4 is arranged on the external diameter of bend pipe, makes the connection bore of interior connecting head be less than the connection bore of outer connecting head, thus achieves the pipeline connecting different tube diameters.As shown in Figure 3, in use, being threaded of the interior connecting head 1 of the less straight tube of caliber and elbow, the larger pipeline of caliber is threaded with outer connecting head 4.
Strengthen the turning that chamber 3 is arranged on bend pipe outside.Strengthen the intensity of chamber 3 for bend pipe turning.If break in the turning of bend pipe, strengthening chamber 3 as tube wall for subsequent use, can also ensure that liquid circulates smoothly, seepage can not occur.Seal ring 5 is arranged on interior connecting head 1, outer connecting head 4, improves the sealing that elbow connects.
The above; be only embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; change can be expected easily or replace, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should described be as the criterion with the protection domain of claim.
