1、禁止在試水和操作階段打開橡膠軟連接螺栓和管道連接螺栓;
1. It is forbidden to open rubber soft connection bolts and pipe connection bolts during water test and operation;
2、橡膠軟連接的安裝長度按球兩端橡膠密封面外側(cè)計(jì)算,產(chǎn)品不流動(dòng);
2. The installation length of the rubber soft joint shall be calculated according to the outside of the rubber sealing surface at both ends of the ball, and the product shall not flow;
