Abstract
The utility model discloses a novel sealing and connecting structure used between straight pipe fittings. The novel sealing and connecting structure comprises the two straight pipelines needing to be connected and a connector. The connector is a straight connector with external threads at the two ends, inner frustum holes are formed in the two ends of the connector, the joints of each straight pipeline are connected with tightening screw caps, flat gaskets and sealing rubber gaskets in a sleeved mode respectively, and the straight pipelines are connected into the connector from the two ends of the connector. The novel sealing and connecting structure used between the straight pipe fittings has the advantages that fastness is achieved, welding is not needed, and the installation speed is more than three times that of flange connection; simplicity is achieved, a pipe connector system is lighter than a flange, the number of bolts is small, and only one wrench is needed for operation; reliability is achieved, and reliable and durable triple guarantees are provided for the pipelines because of scientific and reasonable design; security is achieved, flame operation is not needed in construction sites, no welding slag pollutants are generated in the pipeline, and the structure is especially suitable for fire prohibition construction sites; economy is achieved, and total cost is saved by 10%-20% compared with that of flange connection construction; maintenance and transformation are convenient to achieve, and the pipelines of a pipe system can be cleaned, maintained and replaced at any time.
Description
Technical field
The utility model relates to pipeline connection technology field, is specifically related to the linkage structure between a kind of Novel direct pipe fitting.
Background technique
In prior art, connection between straight pipeline need to be welded, flange connection, tapping connection etc., and these operations all exist shortcoming, and welding can be wasted time and energy and be caused installation rate slow, and get angry in job site, be subject to fire etc., exist welding slag to pollute in pipeline, guard system can not carry out the cleaning of pipeline at any time, safeguard and change, flange connection causes the problems such as link is heavy, bolt quantity is many, and Job Operations is loaded down with trivial details, also larger on cost.
Model utility content
The purpose of this utility model is for the defect of prior art and deficiency, and the linkage structure between a kind of Novel direct pipe fitting is provided.
For achieving the above object, the technical solution adopted in the utility model is:
Linkage structure between a kind of Novel direct pipe fitting described in the utility model, two straight pipelines that comprise that needs connect and joint, described joint is that two ends are with externally threaded straight joint, its two ends are provided with interior frustum hole, and the joint of straight pipeline is socketed respectively tightening nuts, flat gasket and cone seal rubber cushion and from the two ends of joint, accesses joint respectively.
As the preferred embodiment of this programme, the intermediate portion outside of described joint is nut type.
As the preferred embodiment of this programme, described interior frustum hole ecto-entad is gradually narrow.
Preferred embodiment as this programme, the joint of described straight pipeline is taken up in order of priority order to be socketed tightening nuts, flat gasket and cone seal rubber cushion, it is poroid that described seal rubber pad inside is cylinder, and its aperture is slightly larger than the external diameter of straight pipeline, and outside is the taper type coordinating with interior frustum hole.
As the preferred embodiment of this programme, described fastening nut is provided with the interior threaded hole coordinating with joint outside thread near joint one end, and the other end is the flat hole that aperture is slightly larger than straight pipeline external diameter, and outside is nut type.
Adopt after said structure, the utility model beneficial effect is: fast: do not need welding, installation rate is faster more than 3 times than flange connect; Simple and easy: pipe joint system is lighter than flange, bolt quantity is few, operation only needs a wrench, reliable: scientific and reasonable to be designed to triple guarantees that pipeline provides reliable durable, safety: do not get angry in the scene of construction, in pipeline, welding slag pollutes, and is particularly suitable for prohibiting firer ground, economical: to save 10%-20% with flange connect construction overall cost, safeguard that transformation is convenient: guard system can carry out the cleaning of pipeline at any time, safeguard and change, can prevent expanding with heat and contract with cold of pipeline.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical solution of the utility model, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is overall structure schematic diagram of the present utility model.
In figure: 1, straight pipeline, 2, flat gasket, 3, cone seal rubber cushion, 4, tightening nuts, 5, joint, 51, interior frustum hole, 6, straight pipeline.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, linkage structure between a kind of Novel direct pipe fitting described in the utility model, comprise two straight pipelines 1 that needs connect, 6 and joint 5, described joint 5 is that two ends are with externally threaded straight joint, its two ends are provided with interior frustum hole 51, interior frustum hole 51 ecto-entads are gradually narrow, the intermediate portion outside of joint 5 is nut type, spanner easy to use is tightened, straight pipeline 1, 6 joint is socketed respectively tightening nuts 4, flat gasket 2 and cone seal rubber cushion 3 also access joint 5 from the two ends of joint 5 respectively, straight pipeline 1, 6 joint is taken up in order of priority order to be socketed tightening nuts 4, flat gasket 2 and cone seal rubber cushion 3, it is poroid that described cone seal rubber cushion 3 inside are cylinder, its aperture is slightly larger than the external diameter of straight pipeline, outside is the taper type coordinating with interior frustum hole 51, tightening nuts 4 is provided with the interior threaded hole coordinating with joint 5 outside threads near joint one end, the other end is the flat hole that aperture is slightly larger than straight pipeline external diameter, outside is nut type.
During use, first tightening nuts 4, flat gasket 2 and cone seal rubber cushion 3 are set in respectively to the joint of straight pipeline 1,6 according to sequencing, the joint of straight pipeline 1,6 is put in joint 5 and by the interior frustum hole 51 of taper type seal rubber pad 3 aligning joints 5, use spanner to turn tightening nuts 4, just can carry out pipe coupling work, so can realize fast: do not need welding, installation rate is faster more than 3 times than flange connect; Simple and easy: pipe joint system is lighter than flange, bolt quantity is few, operation only needs two wrench, reliable: scientific and reasonable to be designed to triple guarantees that pipeline provides reliable durable, safety: do not get angry in the scene of construction, in pipeline, welding slag pollutes, and is particularly suitable for prohibiting firer ground, economy: save 10%-20% with flange connect construction overall cost, safeguard that transformation is convenient: guard system can carry out the cleaning of pipeline at any time, safeguard and change.
