Abstract
The utility model discloses a steel-plastic composite pipe with a protective device positioned at the port, which is characterized in that the outer wall of the tubular sealing element has a certain taper or zero draft, and is tightly combined with the inner pipe wall of the composite tube. The utility model has the advantages of good sealing, rust protection and negative pressure resistance.
Description
Technical field
The utility model relates to a kind of steel-plastic composite pipe, relates in particular to the steel-plastic composite pipe that a kind of port is equipped with protective equipment.
Background technique
The steel-plastic composite pipe that the straight carbon steel pipe obtains by processing technologys such as inner lining plastic tube or plastic-coateds is the clean tubing of anti-corrosion.But also there are some shortcomings in it in application practice.1, composite pipe incision steel pipe end face easy-to-rust.2, because steel differs from 15 times approximately with the coefficient of linear expansion of moulding, though work in-process was done processing to the expansion coefficient of plastic tube, but under the effect of fed sheet of a media, particularly under delivering hot water's operating mode, the slit very easily at first appears in the port, medium infiltrates gradually and causes the corrosion of steel pipe inwall, steel, moulds integral body and peels off, and the anti-positive and negative pressure ability of pipeline reduces greatly simultaneously.
The model utility content
At above-mentioned deficiency, the utility model provides a kind of port to be equipped with the steel-plastic composite pipe of protective equipment.
For achieving the above object the utility model by the following technical solutions: a kind of port is equipped with the steel-plastic composite pipe of protective equipment, pipe and outer tube in comprising, and it is characterized in that: the port at described composite pipe is equipped with protective equipment.
A kind of port is equipped with the steel-plastic composite pipe of protective equipment, it is characterized in that, described protective equipment is that the cross section is " L " type tubular seal.
A kind of port is equipped with the steel-plastic composite pipe of protective equipment, it is characterized in that, described protective equipment is that the cross section is " C " type tubular seal.
A kind of port is equipped with the steel-plastic composite pipe of protective equipment, it is characterized in that, the outer tube wall of described tubular seal has certain taper, and the outer tube wall of described tubular seal and the inner pipe wall of described composite pipe are combined closely.
A kind of port of the utility model is equipped with the steel-plastic composite pipe of protective equipment, " L " type confidential paper or " C "
The type Sealing is coated on the port of steel-plastic composite pipe, and the outer tube wall of " L " type or " C " type Sealing has certain tapering, and the multiple tube inner tube tube wall is produced outside tension force.Can reach sealing, antirust, the effect of anti-negative pressure.
Description of drawings
Fig. 1 is a L type seal configuration schematic representation;
Fig. 2 is a C type seal configuration schematic representation;
Fig. 3 is equipped with the schematic representation of the steel-plastic composite pipe of L type Sealing for port;
Fig. 4 is equipped with the schematic representation of the steel-plastic composite pipe of C type Sealing for port.
Embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, steel-plastic composite pipe 1, pipe 3 and outer tube 2 in comprising, pipe 3 is a plastic tube generally speaking, outer tube 2 is a steel pipe, the outer tube wall 6 of C type Sealing 4 and L type Sealing 5 has a close tapering (also can make the Sealing that inside and outside tube wall does not have tapering), combines closely with interior pipe 3 tube walls of steel-plastic composite pipe 1.The multiple tube inner tube tube wall is produced outside tension force.Can reach sealing, antirust, the effect of anti-negative pressure.
Claims (4)
1, a kind of port is equipped with the steel-plastic composite pipe of protective equipment, pipe and outer tube in comprising, and it is characterized in that: the port at described composite pipe is equipped with protective equipment.
2, a kind of port according to claim 1 is equipped with the steel-plastic composite pipe of protective equipment, it is characterized in that, described protective equipment is that the cross section is " L " type tubular seal.
3, a kind of port according to claim 1 is equipped with the steel-plastic composite pipe of protective equipment, it is characterized in that, described protective equipment is that the cross section is " C " type tubular seal.
4, be equipped with the steel-plastic composite pipe of protective equipment according to claim 1,2 or 3 described a kind of ports, it is characterized in that, the outer wall of described tubular seal has certain taper or does not have tapering, and the outer wall of described tubular seal and the inner pipe wall of described composite pipe are combined closely.
