Technical Field
[0001] The utility model relates to the technical field of FRP pipe fittings, and specifically relates to a multifunctional FRP pipe fitting. Background Technique
[0002] At present, most of the FRP pipe fittings on the market are single-functional pipe fittings (such as single properties like static conduction, flame retardancy, acid and alkali resistance, solvent resistance, etc.). However, due to the increasing market demand, the demand for FRP pipe fittings is not satisfied with single functionality, and more functions need to be combined.
[0003] There is a existing multifunctional FRP pipe fitting (application number: 202321094254.5) that can endow the FRP pipe fitting with the functions of flame retardancy and static conduction. The flame retardant layer and the conductive layer are arranged alternately, thereby being able to reduce the production cost of the FRP pipe fitting. However, the above still has problems. When the FRP pipe fitting is used for transporting liquid, and after the FRP pipe fitting is installed, if it is squeezed by external objects, it is not convenient to buffer the squeezing external force, which is likely to cause damage to the FRP pipe fitting. Moreover, when the FRP pipe fitting is in use, affected by the use environment, it is not convenient to improve the corrosion resistance of the FRP pipe fitting, affecting the service life of the FRP pipe fitting. Content of the Utility Model
[0004] The purpose of the utility model is to solve the drawbacks in the prior art that it is not convenient to buffer the squeezing external force, which is likely to cause damage to the FRP pipe fitting, and it is not convenient to improve the corrosion resistance of the FRP pipe fitting, affecting the service life of the FRP pipe fitting, and to propose a multifunctional FRP pipe fitting.
[0005] To achieve the above purpose, the utility model provides the following technical solution:
[0006] Design a multifunctional FRP pipe fitting, including a pipe body. A rock wool layer is fixedly connected to the outer wall of the pipe body, and a buffer structure is provided on one side of the rock wool layer.
[0007] Preferably, the buffer structure includes a rubber layer. The inner wall of the rubber layer is fixedly connected to the outer wall of the rock wool layer, and through holes are processed on one side inner wall of the rubber layer.
[0008] Preferably, a flame retardant layer is fixedly connected to the outer wall of the rubber layer.
[0009] Preferably, an epoxy resin paint layer 1 is fixedly connected to the outer wall of the flame retardant layer.
[0010] Preferably, a wear-resistant layer 1 is fixedly connected to the outer wall of the epoxy resin paint layer 1.
[0011] Preferably, an epoxy resin paint layer 2 is fixedly connected to the inner wall of the pipe body.
[0012] A multifunctional FRP pipe fitting proposed by the present utility model has the beneficial effects that: through the cooperation of the pipe body and the buffer structure, when the device is in use, the rubber layer can be styrene-butadiene rubber, and styrene-butadiene rubber has the characteristics of wear resistance, cold resistance, good resilience and small permanent deformation. Therefore, when the pipe body is extruded by an external force, the rubber layer is extruded, thereby playing a buffering role, facilitating the buffering of the external extrusion force, and avoiding damage to the FRP pipe fitting.
[0013] Through the cooperation of the pipe body, the first epoxy resin paint layer and the second epoxy resin paint layer, when the device is in use, the first epoxy resin paint layer and the second epoxy resin paint layer have excellent water resistance, acid resistance, alkali resistance and organic solvent resistance characteristics, which is convenient for improving the corrosion resistance of the FRP pipe fitting and increasing the service life of the FRP pipe fitting.
