Description
技术领域 technical field

背景技术 Background technique
基于公知技术的钢制管件一般有钢管管道用弯头、变径和三通等,主要用于钢管管道,连接形式多以焊接或法兰连接为主。当钢制管件用于塑料类管道时,一般采用法兰连接,这就需要制作特殊的纯塑或带骨架钢塑法兰盘用于与钢制管件的连接,增加成本,当塑料类管道采用法兰连接密封时,由于管道本体热胀冷缩受环境温度和介质温度变化影响较大,所以法兰密封应用于塑料类管道连接并不可靠,随着时间的推移,法兰密封泄露的几率将会增大,对管道使用安全带来隐患。本实用新型将解决上述钢制管件与塑料类管道的连接密封问题。 Steel pipe fittings based on known technologies generally include steel pipe elbows, variable diameters and tees, etc., which are mainly used for steel pipes, and the connection forms are mostly welded or flanged. When steel pipe fittings are used for plastic pipes, flange connection is generally used, which requires special pure plastic or steel-plastic flanges with skeletons to be used for connection with steel pipe fittings, which increases costs. When plastic pipes are used When the flange connection is sealed, because the thermal expansion and contraction of the pipe body is greatly affected by the change of the ambient temperature and the temperature of the medium, the flange seal is not reliable when applied to the plastic pipe connection. As time goes by, the probability of flange seal leakage It will increase, which will bring hidden dangers to the safety of pipeline use. The utility model will solve the connection and sealing problem of the above-mentioned steel pipe fittings and plastic pipes.
