Introduction: When the temperature reaches 95 ℃, the gasket can be made of grey paper cypress because it is more firm than rubber hemp cloth. The rubber linen cloth will be eroded by steam or water pressure. Before filling, the gasket should be soaked in the dry oil (tung oil). If there is any situation, the gasket should be soaked in the dry oil (tung oil)

When the temperature reaches 95 ℃, the gasket can be made of grey paper cypress. The reason why paper cypress is used is that it is more firm than rubber hemp cloth. The rubber linen cloth will be eroded by steam or water pressure. Before filling, the gasket should be soaked in the dry oil (tung oil). In case of any situation, the manufacturer must be required to replace and return the goods Expansion joint Not in the production process is not qualified products, that is, expansion joint refurbished parts, must not covet small cheap, be deceived.
The DN80 water pump supplies five DN80 water pipes at the same time, so the water pressure is not high. The pressure of the emergency expansion joint is set at 0. The expansion joint has a certain multi-directional displacement in the pipeline operation, and plays an important expansion compensation role in the pipeline operation due to heat expansion and contraction, crustal subsidence and stress. Therefore, the expansion joint can relieve the blind plate thrust during the pipeline operation The pipeline plays a certain protection, especially provides convenience for the installation and maintenance of the pipeline.
B2F type double flange limited expansion joint is suitable for both sides to be connected with flange. The single flange loose sleeve limited expansion joint is a limit screw device added on the basis of the expansion joint. The pipe can freely expand and expand in the allowable expansion amount. Once the expansion amount exceeds the limit, the double nut of the screw locking expansion and contraction can play a limiting role, and compensate the pipeline due to thermal expansion and cold contraction or foundation The pipeline axial displacement, distortion and eccentricity caused by sinking protect the connected pump or valve.
book Telescopic device Sealed by rubber ring, the expansion joint itself can not bear the axial tension, so it is generally installed on the straight pipe. Because the series products of expansion joint are metal products, which have high tensile and compressive strength, superior soft sealing performance and convenient loading and unloading, they are widely used in electric power, metallurgy, chemical industry, water supply and drainage, sewage treatment and other industries Connection between valve and pipe.
Adjustment method of expansion amount of double flange expansion joint: double flange expansion joint is composed of loose sleeve expansion joint and a flange limit short pipe. Double flange expansion joint can prevent leakage and damage of compensation joint caused by excessive displacement of pipeline. It is mainly used for loose sleeve connection of pipeline absorbing axial displacement and bearing axial pressure thrust within allowable displacement range When the temperature of the pipe is changed, the pipe can be welded with the foundation automatically.
