Details to be paid attention to when installing the electric ball valve in the water supply pipeline The electric ball valve can be used as a pipeline compensation joint in the water supply pipeline system. When installing the product in the pipeline, it can reduce the pressure thrust (blind plate force) of the connected parts and the error caused by the installation of the compensation pipeline. When the electric ball valve is used to connect the horizontal water supply pipeline, it is not set with a certain slope, and the height of the start end and the end end are the same. When the water supply pipeline fails and needs maintenance, it is difficult to drain the water in the pipeline and the double flange electric ball valve completely, forming water in the pipeline, which will bring difficulties to maintenance. In order to facilitate maintenance, when using double flange electric ball valve to connect horizontal pipes, a slope of 0.002-0.005 should be set to form a slope drainage device inside the pipe connected by double flange electric ball valve.
When the electric ball valve connecting pipe passes through the external wall of the structure, no waterproof measures will be taken, which will cause a certain gap between the external wall of the pipe and the external wall. When it rains or snows, water will seep into the basement or underground structures from the gap, resulting in leakage. In serious cases, the structure of the structure will be damaged, affecting the normal progress of production and life. Therefore, When the connecting pipe of double flange force transfer joint passes through the wall, certain waterproof measures shall be taken, such as filling the gap with hard materials to prevent leakage, or penetrating the wall with a certain slope to make the outside low and the inside high, so as to avoid leakage into the interior of the structure.
