Installation of telescopic pipe butterfly valve installed on the left and right sides of the butterfly valve are possible, but must be added on both sides of the branch, side must be fixed, because the expansion joint can not withstand the axial pressure of the pipe and pipe gravity, telescopic section Can be divided into two major categories of force transmission and limit telescopic transmission, the transmission force is mainly to compensate for installation error, can not compensate for the displacement due to thermal expansion and contraction after installation, can withstand the axial pressure of the pipeline, Limit telescopic can compensate for installation errors and thermal expansion and contraction displacement, can only limit the installation position, but can not withstand the axial pressure on the pipe, the installation must be considered the maximum amount of each telescopic pipe can not exceed Selection of telescopic section of the rated expansion and contraction, the other two sides must have London, while the side is fixed, the branch that can withstand axial pressure pipe thrust and gravity. Can be reserved for tee, telescopic section can compensate for the installation error!
