Description

Technical Field

[0001] The present invention relates to the technical field of pipeline connectors, and in particular to a PE pipeline connector with multiple protection functions. Background Art

[0002] PE pipes are made of polyethylene (PE) and are widely used in water supply, drainage, irrigation and other fields. PE pipes have the advantages of corrosion resistance and chemical erosion resistance in conveying water, which makes them a very popular choice in modern water supply systems.

[0003] The most commonly used connection methods for water supply polyethylene pipes are: hot melt connection, electric fusion connection, socket-type flexible connection, flange connection, steel-plastic transition joint connection, etc. The details are as follows:

[0004] 1. Hot melt connection

[0005] Hot melt connection is to use a special heating tool to heat the parts of polyethylene pipes or fittings to be connected under pressure, melt them, remove the heating tool, apply pressure to connect the two molten surfaces together, and keep them under stable pressure for a period of time until the joint cools down. Hot melt connection includes hot melt butt connection, hot melt socket connection, and hot melt saddle connection.

[0006] 2. Electric fusion connection

[0007] The electric fusion connection is to use a special electric fusion pipe fitting with an embedded resistance wire to closely contact the connecting part of the pipe or pipe fitting and energize it. The embedded resistance wire heats the connecting part to melt it into one until the joint cools down. The electric fusion connection can be used to connect polyethylene pipes or socket fittings of different types and different melt flow rates. The electric fusion connection is divided into electric fusion socket connection and electric fusion saddle connection.

[0008] 3. Socket-type flexible connection

[0009] The socket-and-spigot flexible connection of polyethylene pipe is a new type of connection developed with reference to the socket-and-spigot flexible connection principle of cast iron pipe and polyvinyl chloride pipe (PVC U). It is to weld a reinforced polyethylene socket on one end of the polyethylene pipe. The socket-and-spigot flexible connection is to directly insert one end of the polyethylene pipe into the special socket of the pipe or pipe fitting, and to achieve the purpose of connecting the pipe and the pipe fitting by pressing the locking ring in the socket to resist pulling and the rubber sealing ring to press and seal.

[0010] 4. Flange connection

[0011] Flange connection is mainly used for the connection between polyethylene pipes and metal pipes or valves, flow meters, pressure gauges and other auxiliary equipment. Flange connection mainly consists of polyethylene flange connectors, steel or aluminum back pressure slip-on flanges, steel or aluminum flanges, gaskets or sealing rings, bolts, nuts, etc. Flange connection is achieved by tightening bolts and nuts to make the flange connectors and flanges in close contact.

[0012] 5. Steel-plastic transition joint connection

[0013] Steel-plastic transition joint connection is to connect polyethylene pipes and metal pipes by using steel-plastic transition joints prefabricated by cold pressing or other methods. There are anti-pulling locking rings and sealing rings in the steel-plastic transition joints, which are usually required to have good sealing performance and anti-pulling and pressure resistance performance greater than the polyethylene pipes in the system.
