Description
Technical field
The present invention relates to tubing and manufacture field, be specifically related to a kind of preparation facilities installing the steel-plastics composite pipe of stainless steel lining additional.
Background technology
Existing lining moulds plough groove type and external thread connected type steel-plastics composite pipe, easily ftractures and gets rusty, have a strong impact on the service life of pipeline at tubing two end, so there is the multiple tube installing the stainless steel lining of flange slip-off preventing at the tubing two ends of steel-plastics composite pipe additional.Stainless steel lining serves the effect of coated protection to pipe end, solves the problem of rustiness that splits, and improves pipeline service life.For steel-plastics composite pipe install stainless steel lining additional time, its adherent problem is the key of product quality.If adherent bad, internal lining pipe can be made to frill, or produce gap between stainless steel lining and steel-plastics composite pipe, thus affect installation.The method of producing inner liner stainless steel multiple tube mainly contains the methods such as blast, drawing, cal rolling.Because explosion method has certain danger, and the use of explosive has many restrictions, and drawing makes the internal diameter of oil pipe reduce, and decreases flow.The equipment also more complicated of mechanical stitch, cost is higher, and these two kinds of methods also have a common shortcoming: be exactly that each point is stressed inconsistent, what stainless steel inner lining tube was fitted is uneven.Some technology are also had to utilize the method for hydraulic buckling that stainless steel bushing pipe is installed in addition, as the Chinese utility model document that the patent No. is ZL201120345177.7, the method of this patent utilization hydraulic buckling is at oil tube inner lining stainless steel composite pipe, make to manage interior each point uniform force, the oil pipe prepared and the laminating of stainless steel bushing pipe are closely.But this patent for be the situation that petroleum pipeline installs stainless steel bushing pipe additional, directly overlap with stainless steel lining at installation process mesohigh oil and contact, be not suitable for the fields such as water supply and drainage; And this device for be the situation installing stainless steel bushing pipe in whole piece oil pipe additional, be not suitable for the situation only needing to install additional at tubing two ends stainless steel lining.
Summary of the invention
The object of the invention is to address the deficiencies of the prior art, provide a kind of preparation facilities installing the steel-plastics composite pipe of stainless steel lining additional, the technical scheme of employing is as follows:
A kind of preparation facilities installing the steel-plastics composite pipe of stainless steel lining additional, comprise fueller, also comprise expansion gear, described expansion gear comprises oil connection, balloon core, be embedded in the oily core rod of mistake of balloon in-core, the positioner being installed on the expansion sleeve on balloon core and being installed on oily core rod two ends, during work, described oil connection is connected with the out splice going splice of fueller, the oil supply gallery into balloon core fuel feeding is provided with in the oily core rod of described mistake, the input of described oil supply gallery is connected with oil connection, the output core rod oil-through hole passed through on oily core rod of described oil supply gallery is balloon core fuel feeding, described positioner is used for preventing balloon core and expansion sleeve axially-extending.
During work, fueller supplies hydraulic oil to expansion gear, and after hydraulic oil injects balloon core, balloon core and expansion sleeve two ends, under the stop restriction of positioner, can swell to radial compliance.After pressure release, pushed back by balloon core and reduce under the effect of expansion sleeve elastic shrinkage, preparation facilities is retracted and is exited.Traditional apparatus structure preparing stainless steel lining line plastic-steel tube is complicated, and cost is higher.And what in installation process, stainless steel lining and steel-plastics composite pipe were fitted is uneven.And apparatus structure of the present invention is simple, low cost of manufacture.And expand equably because balloon core and expansion sleeve are slowly radial, stainless steel lining each point uniform force can be made, realize stainless steel lining is evenly arranged on steel-plastics composite pipe tubing port without dead point ground swelling.
As preferably, described expansion sleeve is polyurethane elastic force cushion rubber.
As preferably, described expansion sleeve is sleeved on balloon core.
As preferably, described positioner comprises and was installed on the pipe centring ring of oily core rod on one end of oil connection and was installed on oily core rod away from the clamping sleeve on one end of oil connection.
Pipe centring ring and clamping sleeve are hollow cylinder, and after hydraulic oil injects balloon core, balloon core and expansion sleeve two end are under clamping sleeve and the stop of pipe centring ring limit, and swell with realizing radial compliance, while can not axially swell.
Further, described pipe centring ring is also for positioning the insertion depth of stainless steel lining.
In use, described preparation facilities is filled in the stainless steel lining at pipe end place, and make pipe end face, bush drop-preventing falls flange and described pipe centring ring three compress put in place and keep concentric parallel.
As preferably, described pipe centring ring was sleeved on oily core rod on one end of oil connection.
As preferably, described clamping sleeve was arranged on oily core rod away from one end of oil connection by thread.
Compared with prior art, the beneficial effect that the present invention has: preparation facilities structure of the present invention is simple, low cost of manufacture, can make stainless steel lining each point uniform force, realizes stainless steel lining is evenly arranged on steel-plastics composite pipe tubing port without dead point ground swelling.
