Abstract
The utility model relates to a kind of multiple tube link that is adapted at operation in well; Object be to provide a kind of assemble convenient, be adapted at completing in small space pipeline and install, can increase the composite pipe multiple tube link in working life.A kind of multiple tube link, comprise adpting flange, the position that described adpting flange contacts with pipe end arranges the pipe outer shield that tube wall can be surrounded, and pipe outer shield inwall radially arranges groove along it, and nearly adpting flange end face one side of groove arranges U-shaped seal ring; Described adpting flange and pipe outer shield being axially divided into two along adpting flange end face diameter place.The utility model is by arranging seal ring; composite pipe end is protected; the life-span of composite pipe is extended greatly; the link that is simultaneously arranged on composite pipe one end is comprised of two-part; two-part close up and are connected on pipeline; by bolt, both are coupled together, need the setting tool of use small and exquisite, be extremely beneficial in the place of the narrow spaces such as well and operate.
Description
Technical field
The utility model relates to a kind of pipe joint, is specifically related to a kind of multiple tube link that is adapted at operation in well.
Background technique
In prior art, pipeline is widely used the conveying in various fluids, because the oxygen in fluid has corrosive action to pipeline, so in order to extend the working life of pipeline and the corrosion resistance that increases pipeline, conventionally can adopt corrosion-resistant material to make pipeline, as corrosion-resistant macromolecular material or zinc, copper etc., certainly, the price of these resistant materials is also wanted more expensive than common steel, and the intensity of pure macromolecular material can not be compared with steel, so conventionally can be with common iron as base material, at the compound last layer anti-corrosion layer of its appearance, so, provide cost savings and increased the corrosion resistance of pipeline.But, this composite pipe normally connects several pipelines when connecting with several logical links, and the shortcoming of composite pipe maximum is often to occur even break-off of interfacial corrosion between the anti-corrosion layer of its port and base material, its end of pipeline that common like this Placement connects still fully contacts with fluid, and the end of multiple tube still can be corroded.
Model utility content
Main purpose of the present utility model be to provide a kind of assemble convenient, be adapted at completing in small space pipeline and install, can increase the composite pipe multiple tube link in working life.
For achieving the above object, the technical solution adopted in the utility model is: a kind of multiple tube link, comprise adpting flange, the position that described adpting flange contacts with pipe end arranges the pipe outer shield that tube wall can be surrounded, pipe outer shield inwall radially arranges groove along it, and nearly adpting flange end face one side of groove arranges U-shaped seal ring; Described adpting flange and pipe outer shield being axially divided into two along adpting flange end face diameter place.
That is to say that the link that is set in a composite pipe one end is comprised of two-part, two-part are an end face flange altogether and are arranged on the pipe outer shield that composite pipe pipe outer wall can be surrounded on end face flange, composite pipe is provided with to the fixed groove of pipe sunken inside near the position of end, conventionally its processing method is pipe to be suppressed and obtained this fixed groove in past pipe in the position having with a certain distance from tube end with mould, fixed groove groove direction is radially arranging along composite pipe, pipe outer shield is radially also provided with groove along it, groove coordinates with the fixed groove on composite pipe away from the trough rim of flange, described trough rim can just be inserted in fixed groove, so, adpting flange can be fixed on composite pipe tube wall and can not move axially.In groove on pipe outer shield, be provided with U-shaped seal ring, be first U-shaped seal ring to be covered in composite pipe end end is surrounded when mounted, then two links that are divided into two are closed seal ring is fixed in this groove.
Further, described U-shaped seal ring inwall radially arranges a plurality of grooves along it.Can further improve sealing effect like this.
Further, between described adpting flange connecting end surface, pad is set.Pad can be flexible plastic material, plays further seal for pipe joints effect between the adpting flange end face of two pipelines.
The utility model is by the link with composite pipe clamping, and in link, arrange the seal ring of composite pipe end part seal, secondary seal is carried out in composite pipe end, avoided the composite pipe end contact being easily corroded to fluid, the life-span of composite pipe is extended greatly, the link that is simultaneously arranged on one end of a composite pipe is comprised of two-part, during use, two-part are closed up and are connected on pipeline, by bolt, both are coupled together, whole process only need to be used small-sized setting tool, extremely be beneficial in the place of the narrow spaces such as well and operate.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of multiple tube link of the utility model.
Embodiment
With reference to Fig. 1, be described as follows: a kind of multiple tube link, comprise adpting flange 6, the position that described adpting flange 6 contacts with pipe end arranges the pipe outer shield 1 that tube wall 5 can be surrounded, pipe outer shield 1 inwall radially arranges groove along it, and nearly adpting flange 6 end face one sides of groove arrange U-shaped seal ring 4; Described adpting flange 6 and pipe outer shield 1 being axially divided into two along adpting flange 6 end face diameter places; Further, described U-shaped seal ring 4 inwalls radially arrange a plurality of grooves along it; Further, between described adpting flange 6 connecting end surfaces, pad 7 is set.
In conjunction with Fig. 1 and specifically use step to describe the described preferred version of the utility model:
The position that adpting flange 6 contacts with pipe end arranges the pipe outer shield 1 that tube wall 5 can be surrounded, pipe outer shield 1 inwall radially arranges groove along it, nearly adpting flange 6 end face one sides of groove arrange U-shaped seal ring 4, and U-shaped seal ring 4 inwalls radially arrange a plurality of grooves along it; Described adpting flange 6 and pipe outer shield 1 being axially divided into two along adpting flange 6 end face diameter places.First seal ring 4 is covered in composite pipe end composite pipe end environmental sealing, then two halves link is buckled in the groove that in the fixed groove 3 on composite pipe, seal ring 4 compactings is firmly fixed on to pipe outer shield 1, with bolt, two halves link is fixed.Another root composite pipe to be connected is so operation also, and the end face alignment by two adpting flanges 6, arranges pad 7 therebetween, by being arranged on the flange fixed hole 2 of the end face of adpting flange 6, being screwed into bolt two pipelines are linked together.
