Abstract
The utility model relates to a stainless steel sealed pipe fitting stuck with hot melt adhesive, which belongs to the technical field of pipeline connection and is mainly used for stainless steel-plastic composite pipes and can also be used for the interconnection of other composite pipes, metal pipes, plastic pipes, etc. The utility model is characterized in that the stainless steel sealed pipe fitting stuck with hot melt adhesive is composed of a pipe fitting outer sleeve, sealing washers which are arranged on inner walls on both ends and a hot melt adhesive layer. The utility model has the advantages of simple structure, low cost, convenient installation, double-seal, firm connection, detachable performance, previous injection molding of the hot-melt adhesive in the pipe fitting, electric heating, flame heating, wide use ranges, etc.
Description
The bonding formula stainless steel of a kind of hot melt adhesive sealed pipe fittings, belong to the pipeline connection technology field, being mainly used in outer is being connected to each other of composite pipe of plastics for the stainless steel internal layer, also can be used for being connected to each other between the tubing such as other forms of composite metal-plastic pipe, metal tube and plastics.
In the prior art, bonding between traditional metal tube and the metal pipe element generally is to adopt the epoxies adhesive.Being characterized in can be bonding at normal temperatures, but needs after bonding several hours even tens hours ability is solidified and cemented; In a single day another characteristics are bonding strength height, but bond together, then do not have way again and make them separately, and there is leakage phenomenon in poor sealing between the back discovery tube and tube spare if connect, and then must amputate pipe fitting, and replace tubes and pipe fitting are reinstalled again.
The purpose of this utility model is to provide a kind of structure very simple, and fitting operation is easy, double seal.Be connected firmly, in case find that sealing is bad, only need heat again connected pipe is extracted, replace tubes and pipe fitting can be handled again in addition, promptly easily adorn the bonding formula stainless steel of readily removable hot melt adhesive sealed pipe fittings.
The basic principle that is tightly connected according to tubing and the characteristic of hot melt adhesive, at existing questions in the prior art, basic design of the present utility model is: insert at the needs of stainless steel pipe fitting overcoat on that section inwall of connected plastic stainless-steel composite-tubes and be coated with the last layer hot melt adhesive by injection moulding, it is connected port is set with the melting point that just is heated to glue after the composite pipe that forms plastics in the outer stainless steel of seal washer of sealing by external diameter inserts in the above-mentioned pipe fitting overcoat at this overcoat outer surface, thus the realization purpose of design.
The bonding formula stainless steel of hot melt adhesive described in the utility model sealed pipe fittings is characterized in that the sealing pipe fitting is by pipe fitting overcoat 2 with at the seal washer 4 at connected plastic stainless-steel composite-tubes 1 connecting end mouth of pipe place and be injection molding and be coated in above-mentioned pipe fitting overcoat 2 inwalls and the heat-fusing glue layer 3 between connected composite pipe 1 outer wall constitutes.
The utility model has the advantages that: structure is very simple, easy processing and fabricating, cost is low, and fitting operation is easy, double seal, be connected firmly, be heated to 100～120 ℃ of glue and promptly melt, drop to (80～90 ℃) tubing below the softening point of hot melt adhesive and pipe fitting when fusion temperature moment and be bonding lived, in case find that sealing is bad, only need be added to melting point again tubing is extracted, on tubing, put and insert that heat fused gets final product in the pipe fitting overcoat behind the hot melt adhesive film again, very convenient.The utility model product is good seal performance not only, can dismantle, and its heat-fusing glue layer can be injection-moulded on the pipe fitting outer casing inner wall in advance, but both electricity consumptions of heating, also available flame.
Accompanying drawing 1 is that one of the utility model most preferred embodiment assembling back user mode is along axis vertical profile structural representation;
Accompanying drawing 2 is assembled the back user mode along axis vertical profile structural representation for one of the utility model change embodiment.
Further describe structure characteristic of the present utility model as follows with most preferred embodiment in conjunction with the accompanying drawings: on the long inwall of each about 30mm of the upright pipe fitting overcoat of stainless steel 2 two ends, scribble one deck heat-fusing glue layer 3 by injection moulding, be that the mouth of pipe place of insertion end of the composite pipe 1 of plastics has the seal washer 4 by the external diameter sealing at connected skin for the stainless steel internal layer, after composite pipe 1 is inserted in the pipe fitting overcoat 2, promptly be heated to 100～120 ℃ at outer surface, instantaneous temperature is reduced to 80～90 ℃ and is promptly cemented.
Change as present embodiment:
1, pipe fitting overcoat 2 can change into and outer is the compound pipe box of plastics and respectively processes an inner stopper platform that on its two ends inwall seal washer changes plane sealing into for the metal internal layer as shown in Figure 2;
2, the shape of pipe fitting overcoat can change elbow, threeway, reducing etc. into.
