The related statement on the elbow and the extender of the pump valve fitting

Dec 26, 2017

The elbow on the pump valve fittings is an important pipe in the pipeline system.Pump valve accessories on the Angle of the bend is divided into 45 ° and 90 ° 180 °, these three are the most commonly used.According to the needs of the project will have 60 °, and other series of abnormal Angle bend.

The bent material on the parts of the pump valve includes cast iron, stainless steel or alloy steel and its malleable iron, carbon steel, nonferrous metal and plastic.The connection of the pipe will be directly welded (the most commonly used way) flange connection, as well as the thermal fusion connection and its electric fusion connection, thread connection and related socket connection.

The bend of the pump valve fittings is divided into the welding elbow and the punching elbow according to the production process, including the bending head, the casting bend, etc., which are the bending equipment on the pump valve accessories.Of course, it also has other names, including quarter bend and Ai’er bend

The extender on the pump valve accessories is also known as telescopic section, expansion joint, compensator and expansion joint.The extender is divided into steel extender, rubber extender and stainless steel extender according to the material.

The telescopic device on the pump valve accessories can be axial and telescopic in a certain range, which can directly overcome the deviation caused by the pipe docking and non-coaxial direction in a certain Angle.This will greatly facilitate the installation and disassembly of the valve piping, and it will also be able to scale freely in the pipe.When it overcomes the maximum extension, it will be a limit function, which will also ensure the safe operation of the pipe.http://www.pump-casting.com/
