  • Through the valve and pipe connection, forming a plumbing system, can make the fluid flow. Therefore, the valve and the connecting part of the tube is very important, the connection, the operation need to be very careful, so as to avoid leakage and be damaged In addition, the classification of the valve, and sometimes by connecting the structure of the end of the classification. The following describes the most basic "thread connection type", "flange connection type", "welding type"
  • Thread connection type
  • The use of pipe thread connection, mainly for 2 feet below, pressure 1MPa the following connection.
  • Only need to carry on the screw processing, the construction is simple As a result, there is no
  • need for more parts, and very economical, compared with other connection methods.On the contrary,
  • there are also maintenance and installation is inconvenient.Types of thread, including the "internal
  • and external thread", "taper thread and pipe thread"; the valve is mostly used "cone thread".
  • Welding type
  • Valve and pipe direct welding methods,
  • mainly used for highTemperature and
  • high pressure and completely prevent
  • leakage of the pipeline and so on. this
  • The methods include the insertion of a
  • weld type (casing pipe) and the Welding
  • type (butt welding).
  • 1) Socket Welded
  • Under normal circumst
  • ances,the valve of the
  • welding ends of the tube
  • the tube will be inserted
  • welding. Suitable for small
  • size valves 2 inches below.
  • 2)Butt welding type
  • Engage the valve and pipe
  • to form a connection form
  • of the part In order to make
  • the joints for welding,mutual
  • chamfering processing. Suitable
  • for small to large sized valve.
  • Flange connection type
  • The connection part is made into a "collar", using the bolt and nut to connect the flange connection form,
  • which is called the method ofmy size to large size, is generally used in the most extensive way.
