Abstract
This invention discloses glass fiber reinforced plastics external screw thread tube and tube fitting. A circuit of screw tread layer is added on the external surface of the connecting end of glass fiber reinforced plastics tube or tube fitting. The external screw tread is formed on the external surface of screw tread layer by mould. The connecting end external surface of glass fiber reinforced plastics tube or tube fitting is grinded. Then, resin is covered on the connecting end external surface by hand. The glass fiber is winded, after which added corrosion resistant layer. This invention greatly reduces the cost.
Description
Technical field
The present invention relates to the technical field of Glass Steel Tube and pipe fitting, special relevant with the outside thread shaping structure and the processing method thereof of glass fiber reinforced plastic external thread pipe and pipe fitting.
Background technique
At present, the connection of fiber reinforced plastic pipe adopts flange plate to flush or plug-in type connection dual mode usually.It is earlier straight tube (or pipe fitting) 100 to be docked with flange 110 that flange plate flushes, as shown in Figure 1, 2, add paste resin and glass fibre, straight tube (or pipe fitting) 100 docked with flange 110 be fixed together at joint 120, flush by flange 110 again, realize the connection between the pipeline.Plug-in type connects shown in Fig. 3,4, be with straight tube (or pipe fitting) 200 be plugged on sleeve pipe 210 pullover 230 in, add at socket place 220 and to stick with paste resin and glass fibre, straight tube (or pipe fitting) 200 and sleeve pipe 210 are fixed together, realize the connection between the pipeline.These two kinds of Placements to operator's technical requirements than higher, then require the operator that corresponding qualification must be arranged in developed countries such as the U.S., if human negligence occurs, then possibly can't reach corrosion-resistant or withstand voltage index, even the accident generation of seepage occur at connection procedure.Also have these two kinds of Placement speed slow, need 4 hours ability dryings, use after the connection, must stop work when mounted and wait for that cause certain loss, cost is higher relatively.Therefore, these two kinds of Placements have much room for improvement really.
The connecting means that other has a kind of less employing is in glass pipe 300 outer surface threadings 310, shown in Fig. 5,6, and then is connected with female adapter 320, realizes the connection between the pipeline.But, screw thread 310 heavy damages that machining forms pipeline 300 product structures, make tube wall attenuation, the intensity step-down of pipeline 300, cause the withstand voltage and decay resistance of product obviously to reduce.Therefore, do not adopt this Placement in the industry usually.
In view of this, inventor's fiber reinforced plastic pipe interconnection technique of concentrating on studies, finally develop can connect fast, cost is low, glass fiber reinforced plastic external thread pipe and the pipe fitting low to operator's technical requirements, has solved current fiber reinforced plastic pipe and has connected the worry of bringing to the dealer, this case produces thus.
Summary of the invention
The object of the present invention is to provide glass fiber reinforced plastic external thread pipe and pipe fitting and processing method,, reduce running cost to realize the quick connection of fiber reinforced plastic pipe system.
To achieve these goals, solution of the present invention is:
Glass fiber reinforced plastic external thread pipe and pipe fitting increase by a circle screw thread layer at the connecting end outer surface of Glass Steel Tube or pipe fitting, utilize mould directly to form outside thread at the outer surface of screw thread layer.
Described screw thread layer is formed by sticking with paste in the resin of the connecting end outer surface of Glass Steel Tube or pipe fitting and the glass fibre that is wrapped in the connecting end outer surface of Glass Steel Tube or pipe fitting.
The surface of described screw thread layer also has anticorrosion layer.
The processing method of glass fiber reinforced plastic external thread pipe and pipe fitting with the connecting end outer surface polishing of Glass Steel Tube or pipe fitting, is pasted resin in the hand mode of sticking with paste at the connecting end outer surface, and winding upper glass fiber, add anticorrosion layer, by mould, directly matched moulds is made external thread structure.
After adopting such scheme, the present invention is because at the other circle screw thread layer that increases of the connecting end outer surface of Glass Steel Tube or pipe fitting, the connecting end tube wall of Glass Steel Tube or pipe fitting is thickeied greatly, and utilize mould directly to form outside thread at the outer surface of screw thread layer, but not the screw thread that forms by machining, so the externally threaded formation of the present invention has guaranteed that the structure of pipe and pipe fitting product is not destroyed, and has guaranteed intensity, withstand voltage properties and the decay resistance of product.When pipeline connects, the outside thread that forms at the connecting end of Glass Steel Tube or pipe fitting by the present invention and the screw-internal thread fit of female adapter, can realize the quick connection between the pipeline, only half an hour can be dry fixing after the connection, come into operation, overcome existing pipe and pipe fitting Placement technical requirements height to operator, the shortcoming of taking a lot of work during on-the-spot installation fee, avoided because of the long loss that causes shut-down or wait for of installation time, greatly reduce on-the-spot installation cost, improved the feasibility that Glass Steel Tube and pipe fitting connect by outside thread, make it extensively to be promoted the use, economic benefit is very remarkable.

Embodiment
As Fig. 7 and shown in Figure 9, be preferred embodiment of the present invention, the present invention is that example describes with the glass fiber reinforced plastic external thread pipe, as for the glass fiber reinforced plastic external thread pipe fitting similarly, so please in the lump referring to this preferred embodiment.Improvement of the present invention is:
Connecting end outer surface at Glass Steel Tube 1 increases by a circle screw thread layer 2, this screw thread layer 2 as shown in Figure 8 in the present embodiment, form by sticking with paste in the resin 21 of the connecting end outer surface of Glass Steel Tube 1 and the glass fibre 22 that is wrapped in the connecting end outer surface of Glass Steel Tube 1, the surface of screw thread layer 2 also has anticorrosion layer 23.Outer surface at screw thread layer 2 utilizes mould directly to form outside thread.
Specific practice is after the connecting end outer surface grinding process with Glass Steel Tube 1, paste resin 21 in the hand mode of sticking with paste at the connecting end outer surface, and add glass chopped strand mats, twine upper glass fiber 22 again, add anticorrosion layer 23, by special mould, matched moulds is made external thread structure, and Glass Steel Tube 1 and screw thread layer 2 are become one structure fully.This structure had both guaranteed that the structure of pipe and pipe fitting product is not destroyed, and had guaranteed intensity, withstand voltage properties and the decay resistance of product again.
As shown in figure 10, when the present invention applies to the pipeline connection, by the outside thread of screw thread layer 2 on the Glass Steel Tube 1 and the screw-internal thread fit of female adapter 3, can realize the quick connection between the pipeline, only half an hour can be dry fixing after the connection, come into operation, overcome existing pipe and pipe fitting Placement technical requirements height to operator, the shortcoming of taking a lot of work during on-the-spot installation fee, avoided because of the long loss that causes shut-down or wait for of installation time, greatly reduce on-the-spot installation cost, improved Glass Steel Tube and pipe fitting by the feasibility that outside thread connects, made it extensively to be promoted the use, economic benefit is very remarkable.
Above-described embodiment only is explanation technological thought of the present invention and characteristics, its purpose makes those skilled in the art can understand content of the present invention and is implementing according to this, but do not limit claim of the present invention, the equalization that all spirit that discloses according to the present invention is done changes or modifies, and must be encompassed in the claim of the present invention.
