Abstract
The utility model discloses a plug-in connecting piece used to connect stainless steel plastic clad pipes, namely, a plastic pipe having steps which is bonded in a thin wall stainless steel pipe, wherein, the steps of the plastic pipe forms a socket at the connecting part of the connecting piece and the size of the socket is just matched with the size of the pipe needing to be connected. When in use, the inner wall of the stainless steel pipe in the socket is coated with stainless steel to stainless steel bond, and the outer wall of the plastic pipe in the socket is coated with plastic to plastic bond, then the pipe needing to be connected is inserted into the socket, thus the pipe needing to be connected and the connecting piece are agglutinated as a whole. The structure of the connecting piece is simple, the operation of plug-in and bonding connection is convenient and the bond and seal effects of the two interfaces of the stainless steel to stainless steel and the plastic to plastic are excellent.
Description
Technical field
The utility model relates to a kind of link of composite pipe, specifically a kind of plug-in type link that is used to connect plastic stainless-steel composite-tubes.
Background technique
For the advantages that plastic tube good corrosion resistance and metal tube intensity is high is got up, constantly the someone attempts to manufacture experimently various composite pipes, as plastic stainless-steel composite-tubes, insert plastic tube in thin-wall stainless steel, the pipe fitting performance is fine, but connecting means is comparatively complicated, can not be as common plastics tube, connect with the heating and fusing method, can not adopt the method that is threaded into of common metal pipe to connect, but need special-purpose link.Special-purpose link comprises special locking nut, just parts such as matter collar, seal ring, makes loaded down with trivial detailsly relatively, and price is more expensive, thereby has influenced promoting the use of of plastic stainless-steel composite-tubes.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, connecting means is easy, the suitable plastic stainless-steel composite-tubes of good sealing effect connects usefulness link.
For finishing technological scheme that above-mentioned purpose adopts be: the built-in plastic tube that has step of Stainless Steel Tube, bonding between the outer wall of the inwall of Stainless Steel Tube and built-in plastic tube by bonding layer.Described link produces groove because built-in plastic tube has step at connection part, and it is horn-like that groove is, and the bore of groove mouth is slightly larger than the shoulder height of plastic tube at the bottom of the groove.
Described groove position plastic tube outer wall is adapted with taking over internal diameter, and the Stainless Steel Tube internal diameter is consistent with the external diameter of being taken over.
During use, in the groove of link, stainless steel inside pipe wall is smeared stainless steel-stainless steel tackiness agent, and plastic tube outer wall is smeared plastics-plastic binder, will be taken over and insert in the link groove, will be taken over link by tackiness agent to fuse.
The beneficial effect of this programme is: link is simple in structure, inserts bonded type and connects, and is easy and simple to handle, two interfacial adhesion good sealing effects of stainless steel-stainless steel and plastics-plastics; Link is thin-wall stainless steel with the outer surface of being taken over, and unified appearance is attractive in appearance, and internal surface is engineering plastics, corrosion resistance and good.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1: link structural representation;
Fig. 2: link user mode erection drawing.
Among the figure, 1. Stainless Steel Tube, 2. bonding layer, 3. plastic tube, 4. step, 5. groove, 6. flow-guiding mouth is 7. taken over.
Embodiment:
The link structure as shown in Figure 1, the Stainless Steel Tube 1 built-in plastic tube 3 that has step 4, bonding between the outer wall of the inwall of Stainless Steel Tube 1 and plastic tube 3 by bonding layer 2.The link connection part forms groove 5 because of the step 4 of plastic tube 3.Described groove 5 position plastic tubes 3 outer walls are adapted with taking over 7 internal diameters, and Stainless Steel Tube 1 internal diameter is consistent with the external diameter of being taken over 7.
The link user mode is seen Fig. 2, in the groove 5 of link, Stainless Steel Tube 1 inwall is smeared stainless steel-stainless steel bonding layer 2 ', plastic tube 3 outer walls are smeared plastics-metal layers 2 "; will be taken over 7 and insert in the link groove 5, by bonding layer 2 ' and 2 " will be fused by adapter 7 and link.
Be obstructed for preventing that tube fluid from splashing, flow-guiding mouth 6 circular arc lines of plastic tube 3 are bell mouth shape.
Link can be established the groove connection by adapter 7 by an end, but also groove is all established at two ends, two velamens is taken over connect.
