Description
Technical field
The hose coupling of the relevant a kind of petrochemical pipe of the utility model is meant a kind of composite soft tube joint especially.
Background technique
Current composite soft tube joint structure has dual mode:
Before twining, the inside and outside steel wire of the first on plug, places one section seamless steel pipe, with interior steel wire welded at the seamless steel pipe outer surface, layering was smeared epoxy resin and is tied up with finer wire when stretch-resisting layer and sealing layer twined, outer steel wire welded is inserted in a Sheet Steel Pipe after being connected to the seamless steel pipe outer surface, fills a large amount of epoxy resin between steel pipe and outer steel wire and forms.But major defect:
Complex manufacturing, productivity is on the low side limit by the epoxy resin cure time;
2. the flexible pipe yield rate is low, and local damage can not be repaired in pipe shaft defective or the using process in process of production, is directed at the whole piece flexible pipe and scraps;
The flexible pipe manufacture cycle long, the flexible pipe after the production can't carry out the finished product pressure test short time.
It two is to have produced the composite soft tube pipe shaft earlier, then epoxy resin is poured between interior screwed pipe and outer rim, use pipe wrench or chain wrench that joint is screwed in the flexible pipe port, the working pressure machine promotes joint and realizes that by the mold cold fashion of extrusion joint and fitting tightly of pipe shaft form.But major defect:
1. because interior screwed pipe and pipe shaft exist the certain slope external diameter poor, the viscosity large fluidity difference of epoxy resin forms certain interior screwed pipe of damping obstruction and screws in pipe shaft smoothly, and requiring great effort during installation increases working strength of workers;
2. in a large amount of epoxy resin is gathered between screwed pipe and outer rim joint by mould after extrusion stress can't discharge and be prone to outer rim explosion phenomenon;
3. exist epoxy resin to overflow extremely difficult removing the behind the outer rim equally with said method one, flexible pipe can't carry out the finished product pressure test short time.
The composite soft tube joint is that steel part clamps the plastic article pipe shaft, and the compressibility that is had because of plastics itself in the production has certain degree of difficulty in the fastening operation well greater than steel part, adds epoxy resin to fill the gap in joint; Because of the chemical characteristics and the Temperature Influence of fed sheet of a media, the thermal expansion coefficient difference of hose coupling steel part and plastic article pipe shaft is bigger in actual use, causes with occurring relaxation between flexible pipe pipe shaft and joint easily.
The model utility content
The purpose of this utility model provides a kind of composite soft tube joint, with the operation easier of solution hose coupling explained hereafter and the reused value of product, is controlled in the controlled range at material thermal expansion coefficient difference, guarantees that the safety and stability of product is used.
For achieving the above object, solution of the present utility model is:
A kind of composite soft tube joint comprises flexible pipe and is fixed in the joint at flexible pipe two ends, the fixedly connected respectively flange in the outer end of each joint or connect soon, and described joint comprises the interior screwed pipe outer rim outer with being placed on flexible pipe that screws in the flexible pipe; Flexible pipe mainly comprises stretch-resisting layer and is positioned at the outer steel wire and the steel wire that is positioned at stretch-resisting layer inside of stretch-resisting layer outside that flexible pipe is to be folded between interior screwed pipe and the outer rim; Wherein between interior screwed pipe and outer rim, be provided with a rubber y-type seal ring, and the stretch-resisting layer of hose end is the Internal and external cycle that is folded in y-type seal ring, the outside filling epoxy resin of flexible pipe, screwed pipe, flexible pipe are connected with outer rim in realizing.
Screwed pipe is provided with the ring packing wire casing in the described joint, and the rubber Y-shaped ring is filled the sealing wire casing by external force extruding back; Also be provided with two thread grooves, the screw-thread fit that this thread groove is proper and the inside and outside steel wire of flexible pipe forms.
Be provided with reducer between the outer end of screwed pipe and the inner in described; And the outside of outer rim also forms the reducer place of reducing section with screwed pipe in being connected in; In the angle of proper adaptive outer rim of y-type seal ring and interior screwed pipe cooperation place.
Described outer rim reducing section is fixed by welding in the contact matching place of interior screwed pipe reducer.
After adopting such scheme, the utility model is by the setting of dry type rubber y-type seal ring, and can making behind the flexible pipe pipe shaft more earlier, the operation of erection joint shortens the manufacture cycle; Select the material seal ring of anti-chemical characteristics according to the medium of carrying, solve conflicting of fed sheet of a media and sealing material effectively, utilize the bigger compressibility of rubber remedies influence the thermal expansion coefficient difference generation because of medium temperature gap, the loose problem of elimination joint; Epoxy resin is smeared in outer rim inwall and flexible pipe pipe shaft appearance junction, solidify the back and be configured as one with the flexible pipe skin, forming the fixing flexible pipe pipe shaft that hinders draws outward because of pressure, epoxy resin does not directly contact with medium, so after hose coupling is installed, just can carry out pressure test, guarantee the safety and stability use of product, accelerate the delivery rate of product.
