Description
The technical field is as follows:
the invention relates to the technical field of water supply pipelines, in particular to a super-strong alkali-free glass fiber reinforced plastic reinforced water supply pipe, a connection structure and production equipment thereof.
Background art:
glass Fiber Reinforced Plastics (FRP), also known as GFRP, are fiber reinforced plastics, generally glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin matrices, reinforced plastics using glass fiber or its products as reinforcement material. The glass fiber reinforced plastic pipe mainly uses glass fiber and products thereof as reinforcing materials, and uses unsaturated polyester resin, epoxy resin and the like with high molecular components as basic materials. The glass fiber reinforced plastic pipe has the advantages of unique strong corrosion resistance, low energy consumption for transportation, long service life (more than 50 years), convenient transportation and installation, low maintenance cost, low comprehensive cost and the like, and is widely applied to industries such as petroleum, electric power, chemical industry, papermaking, urban water supply and drainage, factory sewage treatment, seawater desalination, gas transportation and the like.
In the field of urban water supply and drainage, the glass fiber reinforced plastic pipe is more and more widely applied due to the characteristics of light weight, corrosion resistance and the like, but the pure glass fiber reinforced plastic pipe has the defects of low load strength, poor impact resistance and low axial tensile capacity, and when the glass fiber reinforced plastic pipe is buried underground and used under a deeper condition, the conditions of pipeline fracture, external impact fracture, axial tensile fracture and pipe explosion caused by foundation subsidence often occur, so that the glass fiber reinforced plastic pipe cannot be used after water supply is stopped. Later, a glass fiber reinforced plastic sand inclusion pipe appears in the market, for example, in the chinese patent application with publication number CN202925604U, a certain amount of quartz sand is added into a glass fiber reinforced plastic pipe to improve the strength of a pure glass fiber reinforced plastic pipe, although the strength of the glass fiber reinforced plastic sand inclusion pipe reaches the standard, the addition amount of the quartz sand does not have a fixed standard, so that when the internal water pressure is too high, the water seepage and water leakage often occur, and finally the glass fiber reinforced plastic sand inclusion pipe is gradually eliminated by the market.
When the existing glass fiber reinforced plastic pipe is connected, as in the Chinese patent application with the publication number of CN206072567U, one end of the pipe is made into a socket while the other end is made into a socket, and the socket is inserted into the socket during connection, the connection mode has the defects that the outer diameter of the socket is larger than that of other parts of the pipe, the socket is greatly stressed after the pipe is installed, and the socket is easy to break to cause water leakage; secondly, the pipeline is settled and displaced in the ground sometimes, so that the socket and the socket are separated, and the connection failure of the socket and the socket occurs.
In conclusion, the existing glass fiber reinforced plastic water supply pipe cannot meet the market demand, and becomes a technical problem to be solved urgently in the industry.
The invention content is as follows:
the invention provides a super-strong alkali-free glass reinforced plastic reinforced water supply pipe, a connection structure and production equipment thereof in order to make up for the defects of the prior art, solves the problems of low compressive strength, weak impact resistance and weak axial tensile strength of the traditional pure glass reinforced plastic pipe, and thoroughly solves the problems of water seepage, water leakage and pipe explosion of the traditional glass reinforced plastic sand inclusion pipe.
