Abstract
The utility model relates to a pipeline connecting structure with adjustable application range, which comprises a conduit, an outer nut and a screwed pipe joint, and also comprises a spherical pipe joint, wherein the inner conical surface of the screwed pipe joint is matched with the spherical surface of the spherical pipe joint, the outer nut is sleeved on the spherical pipe joint and the screwed pipe joint and fixes the spherical pipe joint and the screwed pipe joint together; the guide pipe is matched with the inner hole of the spherical pipe joint and is welded and fixed together at the joint. The utility model discloses on ordinary through coupling's basis, change a coupling joint connection position into the bulb form to with another interior conical surface coupling cooperation, the angle can be according to the needs when the assembly suitable adjustment, has expanded its use extension greatly.
Description
Technical field
Thereby the utility model relates to a kind of pipeline jointing construction that can rotate its Applicable scope of realization adjusting within the specific limits.
Background technique
Machinery all can relate to the complicated pipelines system especially as complex mechanical equipments such as aircraft, aeroengines, because all need pipe-line system to control power source for its proper functioning provides necessary fuel oil, lubricant oil, air, water etc.Complicated pipelines system again, also be nothing but diameter do not wait, different body is formed by connecting through various forms of pipe joints.Should, the pipe-line system that these pipeline connecting parts constitute, especially the joint of pipe-line system all must satisfiedly connect functions such as reliable, withstand voltage.Common pipeline connecting mode is connected to principal mode with the encased nut of screwed pipe joint, but this structure has satisfied not some harsh requirement, like the joint occasion of regulating Applicable scope etc. that can suitably turn an angle.
The model utility content
Thereby providing, the technical problem that the utility model will solve a kind ofly can rotate the pipeline jointing construction of realizing adjustable Applicable scope within the specific limits.
A kind of pipeline jointing construction of adjustable Applicable scope; This pipeline jointing construction comprises conduit, cap nut, is screwed into pipe joint; This linkage structure also comprises the bulb tube joint simultaneously; The inner conical surface that is screwed into pipe joint matches with the spherical surface of bulb tube joint, and cap nut is sleeved on the bulb tube joint and is screwed on the pipe joint, and with the bulb tube joint be screwed into pipe joint and be fixed together; Conduit matches with the endoporus of bulb tube joint, and is weldingly fixed on together in the joint.
The said inner conical surface angle that is screwed into pipe joint is 90～95 degree.
The utility model makes a pipe joint connection part into the bulb shape on the basis of ordinary straight connection for bbreather pipe, and cooperates with another inner conical surface pipe joint, and angle can suitably be adjusted according to the needs in when assembling, has expanded it greatly and has used extension.The utility model is simple in structure, easy to implement, effect is obvious, safe and reliable.
Description of drawings
Fig. 1 is the structural representation of the pipeline jointing construction of the adjustable Applicable scope of the utility model;
Embodiment
From Fig. 1, can find out, the pipeline jointing construction of the adjustable Applicable scope of the utility model by: conduit 1, bulb tube joint 3, cap nut 4, be screwed into pipe joint 5 and form.During assembling; With the ball head branch of bulb tube joint 3 be assemblied in have an inner conical surface be screwed into 5 li of pipe joints; Add cap nut commonly used 4 then and carry out firm fixation, at last conduit 1 is put into the endoporus of bulb tube joint 3, and conduit 1 and bulb tube joint 3 is fastening with welding manner at joint 2 places.Bulb tube joint 3 is an arc structure with the joint that is screwed into pipe joint 5, bulb tube joint 3 can be in the inner conical surface that is screwed into pipe joint 5 the free adjustment angle.The angle beta that is screwed into the inner conical surface of pipe joint 5 is between 90～95 degree.
Compare with existing technology, the utility model is on the basis of ordinary straight connection for bbreather pipe, and wherein a pipe joint connection part makes the bulb shape into, and cooperates with another inner conical surface pipe joint, adds the structural type that cap nut is fastenedly connected.Bulb can turn an angle at inner conical surface as required, and two pipe joints to remain " Contact Pair " form constant, the needs when angle can be according to assembling are suitably adjusted, and have expanded it greatly and have used extension.The utility model is simple in structure, easy to implement, effect is obvious, safe and reliable.The utility model can be popularized and applied to various mechanical industries, and good economic benefits and social benefit are arranged.
Claims (2)
