S313 expansion valve is introduced
S313 expansion valve is also called the slip joint, expansion joint, compensator. Expansion in a certain range can be axial expansion, can overcome the pipe is not within an Angle of axial offset, can greatly convenient valve pipe installation and disassembly, free expansion in the pipeline allows expansion amount, once across its biggest ACTS as expansion amount limit, to ensure the safe operation of pipeline.
Expansion mainly to ensure the safe operation of the pipeline, and has the following functions: compensation Angle to the absorption pipeline axial, lateral, thermal deformation; Vibration absorption equipment, reduce equipment vibration influence on pipeline; Absorb the earthquake, subsidence deformation of pipeline. Bushing expansion for various water supply and drainage pipeline, the installation of a water tower, water pump, water meter, valve conversion provides great convenience, for long distance pipeline due to temperature difference expansion has played a very good regulatory role.

S313 expansion valve installation considerations
1. The installation should be between the maximum and minimum length, root tree actual situation can be adjusted.
2. When installation, loosen the packing pressure plate bolt, adjust the installation length, and ends with the pipe (or valves, water meter) installed according to design requirements, to check whether the packing is good, the pressure on the packing pressure plate, screw down the bolt by diagonal method do not partial pressure, make it stop leakage.
3. The expansion pipe installation after the check valve.
4. The expansion pipe ends must be set piers, it itself is not under axial tension, and prevent pulled off when necessary.
