Abstract
The invention discloses a plastic-coated composite steel pipe. The two ends of the plastic-coated composite steel pipe are provided with a large sleeve head and a small sleeve head respectively. The large sleeve head, the small sleeve head and a plastic-coated composite steel pipe body are integrated. The large sleeve head comprises a sleeve section and a buckle section which are connected together. The sleeve section is located on the side close to the plastic-coated composite steel pipe body. The buckle section is located on the side away from the plastic-coated composite steel pipe body. A protruding snap ring is arranged at the tail end of the buckle section and provided with rubber rings. Multiple grooves are formed in the position inside the snap ring on the buckle section and the rubber rings are arranged in the grooves. The small sleeve head comprises a circular pipe and an annular protrusion arranged at the tail end of the circular pipe inwards. The annular protrusion is further provided with a rubber ring. The plastic-coated composite steel pipe is simple in structure, low in cost, convenient to use and capable of preventing a coating of the plastic-coated composite steel pipe from being damaged in the process of connection. The structure of the large sleeve head and the small sleeve head can be adopted in the plastic-coated composite steel pipe and the structure also can be adopted in steel pipes, pipe fasteners and the like of other types.
Description
Technical field
The invention belongs to pipe technology field, particularly a kind of plastic coated composite steel pipe, also has a kind of tube clamps.
Background technique
In engineering practice, often the pipeline of segmentation need to be linked together.Traditional metallic material pipeline Placement mainly contains the Placements such as screw thread, clip and flange.These traditional Placements easily produce the situation that accessory cannot effectively be connected with pipeline, complex process, and cost is also higher, and because accessory is perishable because of its material, working life is also shorter.
Plastic coated composite steel pipe is also plastic-coated steel, and plastic-coated steel is to take steel pipe as base tube, take plastic powders as cladding material, the last layer of melt surface coating within it plastic layer, and the steel that applies plastic layer or other materials anticorrosive coat in its outer surface painting is moulded joint product.Because the plastic coated composite steel length of tube of finished product is certain, in use for adaption demand, often need after sawed-off to re-use, but the traditional Placement of sawed-off rear use connects, need to carry out secondary operations, its coating of meeting heavy damage during secondary operations, also can reduction of service life.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of plastic coated composite steel pipe, uses this junction button without plastic coated composite steel pipe is carried out to secondary operations, when having guaranteed to connect effect, does not injure coating, has extended the working life of plastic coated composite steel pipe.
Plastic coated composite steel pipe of the present invention, its two ends arrange respectively large pullover and little pullover; Large pullover sleeve sections and the buckle section linking together that comprise is provided with the snap ring of protrusion on buckle section; The little pullover inside annular protrusion that comprises circular pipe and be arranged on circular pipe end.
As the further improvement of technique scheme, described snap ring is arranged on buckle section end.
Another kind as technique scheme improves, and on described snap ring, is provided with cushion rubber.This cushion rubber can stop inside and outside booty and erosion to enter pipeline.
Another kind as technique scheme improves, and on described buckle section, snap ring position is inwards provided with some grooves, and cushion rubber is set in groove.These cushion rubbers can guarantee sealing and the bearing capacity of the pipeline after connection.
Another kind as technique scheme improves, and is also provided with cushion rubber on described annular protrusion.This cushion rubber prevents the thing scratch coatings such as burr of the annular protrusion of little pullover end, can also strengthen the sealability of joint.
As the further improvement of technique scheme, described pullover greatly, little pullover and plastic coated composite steel tube body is one.
A tube clamps, is respectively arranged with large pullover and little pullover described in technique scheme at its two ends.
Plastic coated composite steel pipe of the present invention is simple in structure, and cost is lower, easy to use, during connection, can not cause damage to plastic coated composite steel pipe coating.Not only plastic coated composite steel pipe can adopt large pullover and little pullover structure, and the steel pipe of other type and tube clamps etc. also can adopt such structure.
Accompanying drawing explanation
Fig. 1 is this plastic coated composite steel pipe schematic diagram;
Fig. 2 is two joint plastic coated composite steel pipe connection diagrams.
Embodiment
Below in conjunction with accompanying drawing, a kind of plastic coated composite steel pipe junction button that the present invention is proposed is elaborated.
Embodiment 1
As shown in Figure 1, a kind of plastic coated composite steel pipe two ends arrange respectively large pullover 1 and little pullover 2, large pullover 1, little pullover 2 and plastic coated composite steel tube body 3 are one.Large pullover 1 comprises sleeve sections 1-1 and the buckle section 1-2 linking together, and sleeve sections 1-1 is positioned near that side of plastic coated composite steel tube body, and buckle section 1-2 is positioned at away from that side of plastic coated composite steel tube body.The snap ring 1-3 that is provided with protrusion at buckle section 1-2 end, is provided with cushion rubber on snap ring 1-3.On buckle section 1-2, snap ring 1-3 position is inwards provided with some grooves, and cushion rubber is set in groove.The little pullover 2 inside annular protrusion 2-2 that comprise circular pipe 2-1 and be arranged on circular pipe 2-1 end.On annular protrusion 2-2, be also provided with cushion rubber, also annular protrusion 2-2 can be set, during ringless-type projection 2-2, this cushion rubber is directly installed on circular pipe 2-1 end, little pullover end.
As shown in Figure 2, when plastic coated composite steel pipe connects, large pullover 1 has elasticity, and large pullover 1 of a plastic coated composite steel pipe is enclosed within on another root plastic coated composite steel pipe little pullover 2.Cushion rubber on annular protrusion 2-2 pushes up on the inner-walls of duct of buckle section 1-2, and two plastic coated composite steel pipes are with regard to successful connection.With such Placement, can connect continuously N root plastic coated composite steel pipe.If because length issue need to be by the sawed-off use of plastic coated composite steel pipe, sawed-offly should be arranged on least significant end or that root plastic coated composite steel pipe foremost.This plastic coated composite steel pipe still has large pulloverly or little pullover like this, attaches it to one little pullover or large pullover upper, does not therefore still need secondary operations.
Embodiment 2
Tube clamps, at its two ends, be respectively arranged with identical with structure in embodiment 1 large pullover 1 and little pullover 2, large pullover 1, little pullover 2 and tube clamps body be one.Large pullover 1 comprises sleeve sections 1-1 and the buckle section 1-2 linking together, and sleeve sections 1-1 is positioned near that side of tube clamps body, and buckle section 1-2 is positioned at away from that side of tube clamps body.The snap ring 1-3 that is provided with protrusion at buckle section 1-2 end, is provided with cushion rubber on snap ring 1-3.On buckle section 1-2, the inside position of snap ring 1-3 is provided with some grooves, and cushion rubber is set in groove.On annular protrusion 2-2, be also provided with cushion rubber, also annular protrusion 2-2 can be set, during ringless-type projection 2-2, this cushion rubber is directly installed on circular pipe 2-1 end, little pullover end.
