Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of pipe connecting structure, particularly a kind of sealing configuration of pipe joint.
Background technique
In daily life and industrial production, water or other fluids are all generally by Cemented filling, are being connected by adjacent pipeline, or when being connected with valve body, tap etc. by pipeline, need to use pipe coupling.At present, start to use plastic pipe in a large number, to replace metallic conduit.Coordinate with plastic pipe, when needs connect the equipment such as valve body, tap, the pipe coupling used generally comprises joint body and metal threaded interior inserter, joint body adopts plastics preparation, in it with can with the inner passage of pipe fitting conducting, so-called metal threaded interior inserter, is inlaid in the inner passage of joint body by the female metal connecting piece of band exactly, so just can carrys out connecting tube by metal threaded interior inserter.
Existing metal threaded interior inserter is hollow tubular structure, one end is at least provided with three card bases protruded, the outer surface of interior inserter offers two grooves usually, inwall arranges female thread structure, metal threaded embedded component is embedded in pipe coupling body interior by the mode of molding and forming, arranging of fastener structure can prevent embedded component from rotating in use, arranging of groove can prevent inserter in metal from getting loose, avoid coming off out in pipe coupling body, female thread structure is used for pipe coupling and the leading connection waiting accessory.
But, in actual use, when the internal thread of pipe coupling and the equipment connection such as valve body or tap, need to seal, in prior art, often adopt the mode twining raw meal belt between internal thread and outside thread to carry out linear sealing, it needs to adopt the pipe wrench of specialty to tighten, just can reach sealing effect, in addition, what raw meal belt sealing adopted is linear sealing, its sealing effect is poor, and As time goes on its sealing effect easily lost efficacy.
Summary of the invention
The purpose of this utility model there are the problems referred to above for existing technology, proposes the pipe joint sealing structure that a kind of structure simple seal is effective.
The purpose of this utility model realizes by following technical proposal: a kind of pipe joint sealing structure, comprise tubular body, it is characterized in that, described inner body wall is provided with internal thread, the inwall of described body end is provided with inwardly protruded ring-shaped step, and described inner body wall is provided with annular cavity near ring-shaped step side, is provided with lip ring in described annular cavity, described Sealing sidewall is resisted against inner body wall, and bottom is resisted against on ring-shaped step.
In above-mentioned pipe joint sealing structure, described Sealing comprises department of assembly and sealed department, and described department of assembly embeds in annular cavity, and described sealed department is resisted against on the screw thread of inner body wall, and described department of assembly and sealed department are integral type.
In above-mentioned pipe joint sealing structure, described inner seal diameter is identical with the internal diameter of ring-shaped step.
In above-mentioned pipe joint sealing structure, described Sealing cross section is square, and described department of assembly is identical with sealed department internal diameter, and described department of assembly's external diameter is identical with annular cavity internal diameter, and described sealed department external diameter is identical with body internal diameter.
Compared with prior art, the sealing configuration of this pipe joint is by arranging ring-shaped step and annular cavity in pipe socket end, for mounting end Sealing, when pipe joint is threaded with outer tube, forms plane sealing by Sealing between the end of outer tube and pipe joint, effectively improve sealing, in addition, it is easy to operate, does not need pipe wrench can realize being tightly connected of pipe joint and pipe fitting, improves the applicability of product.
Accompanying drawing explanation
Fig. 1 is the sectional structure schematic diagram of this pipe joint sealing structure.
In figure, 1, body; 2, ring-shaped step; 3, annular cavity; 4, Sealing; 41, department of assembly; 42, sealed department.
Embodiment
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1, this pipe joint sealing structure, comprise tubular body 1, described body 1 inwall is provided with internal thread, the inwall of described body 1 end is provided with inwardly protruded ring-shaped step 2, and described body 1 inwall is provided with annular cavity 3 near ring-shaped step 2 side, is provided with lip ring 4 in described annular cavity 3, described Sealing 4 sidewall is resisted against body 1 inwall, and bottom is resisted against on ring-shaped step 2.Described Sealing 4 comprises department of assembly 41 and sealed department 42, and described department of assembly 41 embeds in annular cavity 3, and described sealed department 42 is resisted against on the screw thread of body 1 inwall, and described department of assembly 41 and sealed department 42 are integral type.Described Sealing 4 internal diameter is identical with the internal diameter of ring-shaped step 2.Described Sealing 4 cross section is square, and described department of assembly 41 is identical with sealed department 42 internal diameter, and described department of assembly 41 external diameter is identical with annular cavity 3 internal diameter, and described sealed department 42 external diameter is identical with body 1 internal diameter.
The sealing configuration of this pipe joint is by arranging ring-shaped step 2 and annular cavity 3 in pipe socket end, for mounting end Sealing 4, when pipe joint is threaded with outer tube, plane sealing is formed by Sealing 4 between the end of outer tube and pipe joint, effectively improve sealing, in addition, it is easy to operate, do not need pipe wrench can realize being tightly connected of pipe joint and pipe fitting, improve the applicability of product.
During use, first lip ring 4 is installed in annular cavity 3, the department of assembly 41 of Sealing 4 is connected in annular cavity 3, sealed department 42 is resisted against body 1 inwall, manually rotate and the body 1 of pipe joint is screwed in the link such as valve or tap, the outside of link is provided with the outside thread matched with internal thread, hand rotation pipe joint makes link embed the internal thread of body 1, the end of link is then resisted against the sealed department 42 of Sealing 4, link end and Sealing 4 form plane sealing, effectively improve the sealability of joint, improve operation ease simultaneously, do not need professional tool can realize the assembling of pipe joint.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
