Description
Technical field:
The utility model relates to a kind of composite pipe special purpose interface lining, belongs to the closed conduit connection area, is a kind of steel-plastic composite pipe interface lining specifically.
Background technique:
Steel-plastic composite pipe is made matrix with hot-dip galvanized steel pipe, and at inwall, outer wall also can when needing through the powder melts spraying technology.Applied plastic forms, excellent performance.Compare with galvanized pipe, have anticorrosively, non-corrosive, incrustation, smooth smoothness, cleaning are not nontoxic, advantages such as long service life.According to test, be more than three times of galvanized pipe the working life of steel-plastic composite pipe.Compare with plastic tube, have the mechanical strength height, advantage such as withstand voltage, good heat resistance.Because matrix is a steel pipe, so do not have embrittlement, problem of aging.Can be widely used in FLUID TRANSPORTATION and heating engineerings such as tap water, coal gas, chemical product, be the upgrading regeneration product of galvanized pipe.Because its installation and application is basic identical with traditional galvanized pipe, the pipe fitting form is also identical, and can replace aluminium-plastic composite pipe to play a role in the conveying of heavy caliber tap water, receives praises from customers, and has become the most competitive new material in pipeline market.
There is following defective in steel-plastic composite pipe in popularizing using process: because steel-plastic composite pipe will cut into specification different in size as required in installation process, make outside the section metallic material of pipe end and the adhesive portion between metal tube and the composite material be exposed to.Composite pipe in use can make inner plastic occur breaking and slowly peeling off from the connection section of pipeline because of long-term section is washed away of water, and makes metal layer be exposed in the current and oxidation takes place.Thereby make the tube wall attenuation shorten composite pipe working life, increased the probability of composite pipe generation deformation and seepage.
CN201014210 discloses a kind of jointing of composite plastic pipe, its disclosure is for preventing deformation acting as to composite pipe connecting end setting of cover, do not have the function of covering composite pipe section metal layer and plastic layer, only play the effect that deformation does not take place the inner support interface.
The utility model patent of ZL00249473.6 discloses a kind of FERRULETYPE band neck bush pipe joint, comprise pipe joint 1, lining 2, pipe nut 3, connect pipe 5 and cutting ferrule 4, acting as of this lining 2 from the medial support composite pipe, and this lining only is fit to and the supporting use of joints of rigid pipes.And just from preventing the pre-leakage proof of angle of multiunit tube joint generation deformation, be not exposed to outer metal layer and composite layer and grant asylum, particularly go into water (flow) direction at the composite pipe section.
Improvement of the present utility model is the deficiency at above-mentioned technology, has provided a kind of composite pipe entry one end that is specifically designed to, the neck bush that can also can cooperate other sealed members to use separately.Main effect is to give the exposing metal of metal composite pipe section and composite material and grants asylum and prevent that current scour from forming that composite material peels off and thereby metal rustization pollutes managing interior flowing water; have certain support simultaneously, prevent the action function of metal composite mouth of pipe generation deformation.
Above-mentioned material be the bilateral plug-in connection in installation because composite pipe rigidity and setting angle cause installing non-one-tenths inconvenience, and the bilateral embedded structure makes neck bush that deformation take place easily or fracture takes place and can't well play the effect that supports and seal.
The model utility content:
Problem to be solved in the utility model installs the interface lining additional for the water inlet end by the steel-plastic composite pipe joint, thoroughly avoided high-pressure water flow washing away to the composite pipe section, thereby preventing that composite pipe plastics composite bed from peeling off comes off and metal layer generation oxidative phenomena, the pollution that water quality is caused.
The utility model is achieved through the following technical solutions:
A kind of optimal technical scheme of the present utility model is a kind of steel-plastic composite pipe interface lining, described steel-plastic composite pipe is a hollow tubular with the interface lining, make by hard moulding material of high elasticity or metal, described steel-plastic composite pipe is a funnel shape with the interface lining, ring is given prominence to and be provided with in its big opening end outer, described ring cooperates substantially with steel-plastic composite pipe mouth of pipe external diameter, and described steel-plastic composite pipe stretches into the composite pipe inboard with the osculum end of interface lining, and is embedded on the internal diameter of steel-plastic composite pipe.
Described steel-plastic composite pipe is socketed in the water inlet end of every section steel-plastic composite pipe with the interface lining.
A kind of most preferred technique scheme of the present utility model is that described steel-plastic composite pipe is basic identical with the big opening end and the composite pipe nozzle diameter of interface lining, and described ring covers the metal layer and the composite layer of composite pipe water inlet end end face.
The overall technical architecture of the supporting installation pipeline of the utility model is a kind of water-feeding ﹠ drainaging pipeline that is made of with interface lining and steel-plastic composite pipe steel-plastic composite pipe, it comprises the peripheral hardware connecting sleeve, steel-plastic composite pipe interface lining, steel-plastic composite pipe A and steel-plastic composite pipe B, the periphery to be connected that described peripheral hardware connecting sleeve is provided with described steel-plastic composite pipe A of seal groove and B is provided with at least one circle inner annular recess, one circle outer annular recess is set in the described peripheral hardware connecting sleeve in week at least, described peripheral hardware connecting sleeve is provided with interface lining fixed groove in its corresponding steel-plastic composite pipe connection part inside, be provided with the lockhole corresponding near the interface of described steel-plastic composite pipe A and B with outer annular recess, described peripheral hardware connecting sleeve is connected steel-plastic composite pipe A by the bolt that inserts lockhole with B, in the described connecting sleeve inner seal ring recess seal ring is housed, described steel-plastic composite pipe is fixed in the interface lining fixed groove on the peripheral hardware connecting sleeve with the outer of interface lining.
The further improvement technological scheme of the supporting installation pipeline of the utility model is that described lockhole is a spiral hole, and promptly the axis of lockhole is inc.
The beneficial effects of the utility model are by above technological improvement, prolonged the working life of the water supply line that uses the steel-plastic composite pipe construction, and Security have obtained corresponding raising.Prolong the time of changing and maintaining pipeline, reduced energy consumption and personnel labor intensity, saved the social resources cost.And the interior water quality of pipe is cleaned for a long time.
