What should be paid attention to when embedding Zhuhai flexible electric butterfly valve. Zhuhai flexible electric butterfly valve can be used as a kind of embedded part for structures with vibration or strict waterproof requirements where the pipeline passes through the wall. When embedding the flexible electric butterfly valve, attention shall be paid to that when more than two casings of the same pipe are reserved in a straight line, the line shall be drawn to ensure that the center line is on the same straight line; when the rows of pipe casings with the same elevation are reserved, the level ruler or horizontal pipe shall be used to read the level.
When the casing of the upper and lower parallel pipes is reserved, the plumb wire device is used. It is necessary to have high standards and strict requirements for reserved operations. All reserved openings shall have correct coordinates and elevations, and the openings shall be smooth and even. In case of broken reinforcement, it is necessary to obtain the approval of the civil engineering discipline in advance and adopt the necessary treatment methods before the reinforcement can be broken.
Since the space at the bottom of the flexible electric butterfly valve is small, when the concrete flows to the flexible electric butterfly valve, the vibrating rod should be immediately penetrated for vibration. When vibrating the concrete of flexible flexible electric butterfly valve, special personnel shall be assigned to stand beside the casing. When the concrete is poured to the bottom of the flexible flexible electric butterfly valve, the vibrating rod shall be used to vibrate continuously on the inner wall of the flexible casing, and the hammer shall be used to knock the inner wall of the casing and the formwork of the pool wall one by one manually to ensure the effective combination of the outer wall of the casing and the concrete.
