Abstract

The utility model relates to a kind of pipe joint, comprise the flange plate I and flange plate II that are mutually installed together, described flange plate I and flange plate II are provided with the mounting hole of centering, all protruding on described flange plate I and flange plate II have gear cylinder, flange plate I is provided with boss, corresponding flange plate II offers groove; Be provided with toroidal cavity in the middle of the end of described flange plate I and flange plate II, described flange plate I and the interconnective end face of flange plate II are provided with seal ring.The utility model, by being provided with seal ring on flange plate I and flange plate II, improves its sealability; Toroidal cavity is set simultaneously, on the one hand lightening material, carrying when being convenient on the other hand install; By being provided with boss and groove, being convenient to install, improving and effect is installed.

Description

A kind of pipe joint
Technical field
The utility model relates to pipeline connection area, particularly relates to a kind of pipe joint.
Background technique
It is exactly two pipelines, pipe fitting or equipment that pipeline connects, and is first fixed on separately on a flange plate, and then adds flange gasket between two flange plate, be bolted together, complete connection.Some pipe fittings and equipment carry flange plate, are also belong to Flange joint.Flange joint realizes sealing by tightened bolt presses pad, in general, fluid has two kinds of forms in the leakage at pad place, i.e. so-called " infiltration leakage " and " boundary leakage ", infiltration leakage is the leakage of fluid by this capillaries of gasket material, main relevant with structure with the material of pad; And boundary leakage be fluid from pad and flange contact boundary leakage, main relevant to interfacial gap size.In prior art, the volume of flange is large, weight large, effort is compared in transport installation, and sealing effect is poor simultaneously, and for the occasion that some seal requests are higher, general flange does not often reach usage requirement.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of pipe joint, the good sealing effect while that it being lightweight, is convenient to install.
The utility model technical solution problem adopts following technological scheme:
A kind of pipe joint, comprise the flange plate I and flange plate II that are mutually installed together, described flange plate I and flange plate II are provided with the mounting hole of centering, all protruding on described flange plate I and flange plate II have gear cylinder, flange plate I is provided with boss, corresponding flange plate II offers groove; Toroidal cavity is provided with in the middle of the end of described flange plate I and flange plate II.
As optimal technical scheme of the present utility model, described flange plate I and the interconnective end face of flange plate II are provided with seal ring.
As optimal technical scheme of the present utility model, described seal ring is " O " RunddichtringO.
As optimal technical scheme of the present utility model, the inwall of described gear cylinder and the inwall concentric of mounting hole.
As optimal technical scheme of the present utility model, described flange plate I and flange plate II offer concentric threaded mounting hole.
Compared with prior art, the beneficial effects of the utility model are: the utility model, by being provided with seal ring on flange plate I and flange plate II, improves its sealability; Toroidal cavity is set simultaneously, on the one hand lightening material, carrying when being convenient on the other hand install; By being provided with boss and groove, being convenient to install, improving and effect is installed.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-flange plate I; 2-flange plate II; 3-keeps off cylinder; 4-boss; 5-groove; 6-toroidal cavity; 7-seal ring; 8-threaded mounting hole.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
Described a kind of pipe joint, comprise the flange plate I 1 and flange plate II 2 that are mutually installed together, described flange plate I 1 and flange plate II 2 are provided with the mounting hole of centering, all protruding on described flange plate I 1 and flange plate II 2 have gear cylinder 3, flange plate I 1 is provided with boss 4, corresponding flange plate II 2 offers groove 5; Toroidal cavity 6 is provided with in the middle of the end of described flange plate I 1 and flange plate II 2.
Described flange plate I 1 and the interconnective end face of flange plate II 2 are provided with seal ring 7, and described seal ring 7 is " O " RunddichtringO.
The inwall of described gear cylinder 3 and the inwall concentric of mounting hole, described flange plate I 1 and flange plate II 2 offer concentric threaded mounting hole 8.
In sum, the utility model, by being provided with seal ring on flange plate I and flange plate II, improves its sealability; Toroidal cavity is set simultaneously, on the one hand lightening material, carrying when being convenient on the other hand install; By being provided with boss and groove, being convenient to install, improving and effect is installed.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
