Abstract
The invention provides a connecting method for a line plastic-steel tube which is characterized in that a plastic layer is lined in a steel tube and two ends of the steel tube are covered by the plastic layer. A notch formed by rolling a slot is disposed on a steel tube layer close to the end of the line plastic-steel tube. A seal ring which is a U-shaped ring for completely sleeving the end of the line plastic-steel tube is disposed on the end of the line plastic-steel tube. The ends of the line plastic-steel tube sleeved with the seal ring are opposite to clamp the notch on the line plastic-steel tube by a hoop, so two line plastic-steel tubes can be tightly coupled. The hoop is provided with a hoop seal ring which can seal the edge of the U-shaped seal ring.
Description
Technical field
The present invention relates to a kind of connecting means of line plastic-steel tube, this method belongs to the groove connecting means of line plastic-steel tube.
Background technique
Line plastic-steel tube has been extensive use of the installation of water engineering, and in actual use, the heavy caliber line plastic-steel tube adopts the groove connecting means, and implementation methods is simple, convenient disassembly.Because when the line plastic-steel tube groove that uses connects at present, earlier the lining inner surface of tubes with plastics layer then slot rolling cause the two-sided roller clip of slot rolling equipment top plastic layer, excessive velocities during operation, excessive or the steel pipe of pressure and the not high generation of plastic layer adhesive strength is come unstuck or come unstuck in the part, and the pipe end seal ring is not installed, also not at steel pipe end face coating plastic layer, during use, press water washes away plastic layer makes press water enter interlayer, thereby washes the glued film that plastic layer is connected with steel pipe open make the plastic tube displacement that pipeline obstruction take place Accident due to quality.
Summary of the invention
The invention provides a kind of connecting means of line plastic-steel tube, it is characterized in that, lining inner surface of tubes with plastics layer and plastic layer coat the both ends of the surface of steel pipe, on the close steel pipe layer of line plastic-steel tube end face, has the notch that slot rolling obtains, on the line plastic-steel tube end face, seal ring is housed, the sealing circle is for coating the U type circle of line plastic-steel tube end face fully, the line plastic-steel tube end face that will be with seal ring then is relatively with the notch on the clip chucking line plastic-steel tube, thereby make two line plastic-steel tubes be tightly connected, and also have the clip seal ring in the clip, the clip seal ring can be so that the edge of U RunddichtringO be also sealed.
Wherein, the plastics of inner lining of steel pipe are polyethylene, polypropylene or PVC.
Wherein, the material of seal ring is an ethylene-vinyl acetate copolymer.
Wherein, the material of seal ring is a rubber.
Wherein, the material of seal ring is a teflon.
Line plastic-steel tube connecting means of the present invention, by using the U RunddichtringO, plastic layer Cladding Steel pipe end face, sealing was bad when heavy caliber line plastic-steel tube groove connected in the solution prior art, cause plastic layer and steel pipe to break away from and block the difficult problem of pipeline easily, obtained good social benefit and economic benefit.

Embodiment
In the connecting means of a kind of line plastic-steel tube of the present invention, at the end face A place of steel pipe 2 coating plastic layer, steel pipe 2 plastic lining layers 4 and plastic layer 4 coat the end face A place of steel pipe, on the close steel pipe layer of line plastic-steel tube end face, has the notch that slot rolling obtains, seal ring 3 is housed on the line plastic-steel tube end face, sealing circle 3 is for coating the U type circle of line plastic-steel tube end face fully, the line plastic-steel tube end face that will be with seal ring 3 then is relatively with the notch on the clip 1 chucking line plastic-steel tube, thereby make two line plastic-steel tubes be tightly connected, and also have clip seal ring 5 in the clip 1, clip seal ring 5 can be so that the edge of seal ring 3 be also sealed.
Claims (5)
