Abstract
The utility model provides a layer composite taper neck type plastic composite pipeline joint for a plastic glass pipeline, which is formed by compounding a surface layer 3, an intensity layer 4, a filter layer 5 and a plastic lining pipe 6. The quick connector comprises three types of a loop flange, a quick connector and a flange. The plastic-glass-fiber-reinforced-plastic composite pipeline has the advantages of high strength, good rigidity, reliable sealing and the like, can ensure the safe operation of the plastic-glass-fiber-reinforced-plastic composite pipeline, and is favorable for expanding the popularization and application range of the plastic composite pipeline.
Description
The utility model relates to the pipe joint technical field, is a kind of plastic composition pipeline joint.
The plastic pipe joint is to design according to the rerum natura of line transportation medium and relevant technologies parameter, in view of the joint on the pipeline should bear longitudinal stress, bear circumference stress again, maximum stress value even up to the several times of inner-walls of duct stress value, thereby it is for guaranteeing that sealing, Security that pipeline uses have the important effect of closing that causes.Because the Young's modulus of plastics is far below metallic material, so, if it is irrational the structural design of joint for plastic tube only simply being copied the mode of structure of metal joint, this will make the root of joint distortion, cracking often occur, so that medium phenomenons such as " run, drip, leak " takes place, as carry poisonous, inflammable, explosive medium can cause serious environmental to pollute and human casualty accident.
The purpose of this utility model is at the problems referred to above, considers the characteristic of resin glass reinforced plastics composite pipeline, according to iso-stress, etc. the design principle of allergic effect, and provide a kind of layer of composite conial neck type pipe coupling.
Description of drawings:
Fig. 1: lap joint flange joint schematic representation.
Fig. 2: rapid pipe joint schematic representation.
Fig. 3: flanged fitting schematic representation.
Fig. 4: the utility model layer composite structure generalized section.
The utility model is to realize (referring to Fig. 1-4) like this:
The plastic composition pipeline joint comprises three types of lap joint flange, rapid pipe joint and flanges, its technological points is that joint all adopts the compound awl neck structure of layer, it is composited by surface layer 3, intensity layer 4, transition layer 5, plastic inner lining pipe 6, this joint is divided into end face 1, awl neck 2, the wall thickness of awl neck bottom is 1.5～2 times of pipe thickness, and awl neck height is 1:3 with the ratio of tapering.
Below to other technical characterstic launch the explanation:
The trigonometric form potted line is arranged on the cross section of joint end face 1 and plastic inner lining pipe 6, or half garden camber seal ring.
Adopt the step shiplap mode between compound awl neck of joint layer and the pipeline.
Material of the present utility model is thermoplastic pipes, glass fibre reinforced plastics and auxiliary agent.
Thermoplastic pipes can be PVC, polypropylene, polyethylene, polyurethane, ABS and thermoplastic engineering plastic.
Glass fibre reinforced plastics can be fiber glass epoxy, unsaturated polyester resin glass fibre reinforced plastics, phenolic aldehyde, furans glass fibre reinforced plastics.
Auxiliary agent is conductive material, anti-static agent, fire retardant, ultraviolet light absorber.
In the surface layer 3 in the above-mentioned layer composite structure conductive material is arranged, anti-static agent to reduce surface resistance, makes it become conductive material by insulating material; Flame retardant material is arranged in the intensity layer 4 or adopt flame-retarded resin to guarantee its flame retardant property; Plastic inner lining pipe 6 is selected for use and is had plastic tube antistatic, fire-retardant, wear-resisting, decay resistance concurrently, in order to guarantee adhesion strength between liner and the intensity layer, then in transition layer 5, add the molding powder identical with liner, to regulate linear expansion coeffcient, the Young's modulus of transition layer, avoid intensity layer and liner to break away from.
Manufacture method of the present utility model is: adopt manual pasting forming process, cold-press process and circumvolution to combine.At first plastic inner lining pipe 6 outer surfaces are carried out hacking and handle, insert in the joint shaping die, spraying transition layer 5, with circumvolution processes intensity layer 4, then, with cold-press process processing awl neck, last circumvolution machined surface layer 3.In the resin formula of intensity layer and surface layer processing, put into auxiliary agent.
The utility model embodiment sees Fig. 1-3.
The utility model has following advantage than prior art:
This joint can guarantee pipeline attachment security, reliable, can improve bearing capacity effectively, avoids " run, drip, leak " phenomenon to occur, and is convenient to enlarge applying of resin glass reinforced plastics composite pipeline.
Claims (4)
1, a kind of plastic composition pipeline joint comprises three types of lap joint flanges, rapid pipe joint, flange, it is characterized in that all adopting the compound awl neck structure of layer, it is composited by surface layer 3, intensity layer 4, transition layer 5, plastic inner lining pipe 6, the wall thickness of awl neck 2 bottoms is 1.5～2 times of pipe thickness, and awl neck height is 1: 3 with the ratio of tapering.
2,, it is characterized in that having on the cross section of joint end face 1 and plastic inner lining pipe 6 a kind of structure in trigonometric form potted line or the half garden camber seal ring according to the described joint of claim 1.
