Description

Temporary connector for steel pipes

Technical Field

The invention relates to the field of steel pipes, in particular to a temporary connector for steel pipes.

Background

The building pipeline is connected according to the application and the pipe material by the following common connecting methods: threaded connection, flange connection, welding, groove connection (clamp connection), ferrule connection, clamping connection, hot melt connection, socket connection and the like. The threaded connection is realized by using a pipeline fitting with threads, and galvanized steel pipes with the pipe diameter less than or equal to 100mm are preferably connected by the threads and are mostly used for open-mounted pipelines. The steel-plastic composite pipe is also generally connected by screw threads. The galvanized steel pipe is connected by adopting threads, and the surface of the galvanized layer and the exposed thread part damaged when the galvanized steel pipe is screwed are subjected to anti-corrosion treatment; the flange or the ferrule type special pipe fitting is adopted for connection, and secondary galvanizing is carried out on the welding position of the galvanized steel pipe and the flange. The pipelines with larger diameters are connected by flanges, and the flange connection is generally used at the positions of a main pipeline connecting valve, a check valve, a water meter, a water pump and the like and on pipe sections which need to be frequently disassembled and overhauled. The galvanized pipe is connected by welding or flanges, and secondary galvanizing or corrosion prevention is carried out at the welding position. The joint is suitable for non-galvanized steel pipes, is mainly used for concealed pipelines and pipelines with larger diameters, and is more applied to high-rise buildings. The copper pipe connection can adopt a special joint or welding, when the pipe diameter is less than 22mm, socket or sleeve welding is adopted, the bell mouth is installed in the medium flow direction, and when the pipe diameter is more than or equal to 2mm, butt welding is adopted. The stainless steel pipe can adopt socket welding. The groove type connecting piece can be used for galvanized steel pipes with the diameter of more than or equal to 100mm of fire water, cold and hot water of an air conditioner, water supply, rainwater and the like, and has the characteristics of simplicity in operation, no influence on the original characteristics of pipelines, safety in construction, good system stability, convenience in maintenance, labor and time conservation and the like. The plastic composite pipe is generally pressed by a thread cutting sleeve. Sleeving the fitting nut on the end of the pipeline, sleeving the inner core of the fitting into the end, and tightening the fitting and the nut by using a wrench. The connection of the copper pipe can also adopt the compression joint of a thread clamping sleeve. The steel clamping and pressing type pipe fitting connection technology replaces the traditional water supply pipeline connection technology such as threads, welding, gluing and the like, and has the characteristics of water quality protection, strong corrosion resistance, long service life and the like. The PPR pipe is connected by hot melting through a hot melting device. The connection between cast iron pipes and pipe fittings for water supply and drainage. The flexible connection and the rigid connection are adopted, the flexible connection is sealed by a rubber ring, the rigid connection is sealed by asbestos cement or expansive packing, and lead sealing can be used in important occasions.

The connection of steel pipe generally adopts the welded mode, but in the welded time, time is wasted relatively, if the installation of steel pipe is not suitable, still need dismantle the steel pipe, also some connect through the flange of steel pipe tip, need fasten a plurality of bolts, it is also more troublesome to operate, to the temporary connection complex operation between the steel pipe, also perhaps use the nut to connect, when using the nut to connect, need carry out the slotted screw to the steel pipe, also need the nut that matches simultaneously to connect, therefore, the not enough of prior art is solved to the urgent need of design a steel pipe temporary connection ware.
