Abstract
The invention provides a pipeline connecting connector. According to the connector, no assembly stress is generated when a compressor and an external pipeline are assembled, and an assembly technology is simple. The pipeline connecting connector is applied to connection between the compressor and the external pipeline and comprises a straight pipe section, a straight hole section, a seal groove and a seal ring, wherein the seal ring is installed in the seal groove in a clamped mode, the straight pipe section is in clearance fit with the straight hole section, and the clearance seal is achieved through the seal groove and the seal ring.
Description
Technical field
The present invention relates to mechanical manufacturing field, particularly a kind of pipe joint.
Technical background
In modern mechanical manufacturing technique, along with the output of gas compressor class machinery constantly increases, the intrinsic problem of installing and using of such machine highlights gradually.
Fig. 1 is the flange connection diagram that conventional construction gas compressor air port is connected with external pipeline, comprises that gas compressor 11, external pipeline 12, gas compressor pipe flange 13, external pipeline flange 14, gas compressor footing 15, footing support 16.Such assembly structure, at gas compressor pipe flange 13, external pipeline flange 14 use bolt tightenings, gas compressor footing 15, footing support 16 with after bolt tightening simultaneously, and in 12 formed closed loop dimensional chains of gas compressor 11 and external pipeline, by the size error of processing and assembling generation, can, in the very large erection stress of the interior generation of gas compressor 11, affect the safe operation of main frame.Gas compressor pipe flange 13 and external pipeline flange 14 position narrow spaces, during installation, wrench operated is very difficult.
Fig. 2 is the flexible joint connection diagram that conventional construction gas compressor air port is connected with external pipeline, comprises gas compressor 21, external pipeline 22, gas compressor pipe flange 23, external pipeline flange 24, gas compressor footing 25, footing support 26, flexible joint 27.Such assembly structure, between gas compressor pipe flange and externally connected pipe flange, installs a flexible joint additional, the erection stress producing to eliminate said structure, but general structure size increased a lot, increased the space that unit takies.Gas compressor pipe flange 13, external pipeline flange 14 and 27 liang of end flange position narrow spaces of flexible joint, during installation, wrench operated is very difficult.
In prior art, between structure, the generation of erection stress has had a strong impact on the safe operation of gas compressor, and gas compressor and external pipeline while installing because narrow space makes dismounting operation very difficult.
Summary of the invention
The embodiment of the present invention provides a kind of pipe joint, produce, and assembly technology is simple when to gas compressor and external pipeline assembling without erection stress.
A kind of pipe joint that the embodiment of the present invention provides, being applied to gas compressor is connected with external pipeline, comprise: straight length, straight hole section, seal groove, seal ring, in described seal groove, be installed with seal ring, described straight length and described straight hole section are Spielpassung, by described seal groove and described seal ring, realize clearance seal.
Wherein, described seal groove is arranged at described straight length outer side surface.
Wherein, described seal groove is arranged at described straight hole section inner side surface.
Wherein, the quantity of described seal groove is at least one.
Wherein, described sealing ring material is for tolerating the elastic material of operating temperature.
Wherein, described seal ring cross section is C type, wedge type, X-type or O type.
Wherein, there is enough large chamfering the end of described straight length and described straight hole section.
A kind of pipe joint that the embodiment of the present invention provides, the mode of inserting straight hole section with straight length between gas compressor in/out air tube and external pipeline is connected, make gas compressor and external pipeline when assembling, not form the dimensional chain of sealing, thereby produce without erection stress, and assembly technology is simple.

Embodiment
Below in conjunction with accompanying drawing, the mode of execution of the embodiment of the present invention is clearly and completely described.
The pipe joint that the embodiment of the present invention provides, for connecting gas compressor and external pipeline, arranges seal groove at straight length outer side surface or straight hole section inner side surface, and in seal groove, seal ring is set, and realizes being tightly connected of gas compressor and external pipeline.
Figure 3 shows that the embodiment of the present invention provides for connecting the pipe joint structural representation of gas compressor and external pipeline.As shown in Figure 3, gas compressor 31 is connected with external pipeline 32 by this pipe joint.Wherein, pipe joint comprises: straight length 33, straight hole section 34, seal groove 35 and seal ring 36, seal ring 36 is arranged in seal groove 35.In the present embodiment, 34 designs of straight hole section are on gas compressor 31, and straight length 33 is light pipe, and design is on external pipeline 32, and seal groove 35 is arranged on straight hole section 34 outer side surfaces.Gas compressor 31 also supports being connected and fixed of 38 realizations and external pipeline 32 by gas compressor footing 37 and footing.Owing to being Spielpassung between straight length 33 and straight hole section 34, make unit after installation, between pipe, connect and do not have erection stress to produce, sealing configuration is simple, significantly reduces physical dimension, and only need insert while installing, during dismounting, only need transfer to, assembly technology is simple.
In another embodiment of the present invention, straight hole section 34 can be arranged on external pipeline 32, and straight length 33 is arranged on gas compressor 31; Seal groove 35 also can be arranged on straight length 33 inner side surfaces.
The pipe joint partial schematic diagram providing for the embodiment of the present invention is provided.As shown in Fig. 4 a, this joint comprises: straight length 41, straight hole section 42, seal groove 43, seal ring 44, straight length pipe end chamfering 48 and straight hole sector hole chamfer 49.Wherein, on straight hole section 42 inner side surfaces, be provided with shown at least one seal groove 43(figure one), in seal groove 43, be installed with seal ring 44, sealing circle 44 adopts the elastic material that can tolerate operating temperature to make, its cross section can be C type, O type, X-type or wedge type, respectively as shown in Fig. 4 a, 4b, 4c, 4d.The end of straight length 41 and straight hole section 42 is respectively arranged with pipe end chamfering 48 and nose end chamfering 49, facilitates straight length 41 to insert straight hole section 42.Seal groove 43 also can be arranged on straight length 41 outer side surfaces, as shown in Fig. 4 c and 4d.
A kind of pipe joint that the embodiment of the present invention provides, the mode of inserting straight hole section with straight length between gas compressor in/out air tube and external pipeline is connected, make gas compressor and external pipeline when assembling, not form the dimensional chain of sealing, thereby produce without erection stress, and assembly technology is simple.
Above-described embodiment is only for explanation technical conceive of the present invention and feature, not in order to limit the present invention, within the spirit and principles in the present invention all, any modification of doing, is equal to replacement etc., within all should being included in protection scope of the present invention.
