Quality control measures for delivery inspection of flexible electric ball valve in swimming pool 1. The quality of flexible electric ball valve attaches importance to the inspection of pipe materials. The construction unit is required to select pipes produced by regular manufacturers, and check whether the factory certificate and mechanical test report submitted for inspection of pipes are complete. 2. The quality of flexible electric ball valve attaches importance to the inspection of pipe appearance. After the pipes enter the site, the engineering materialman shall inspect the appearance of the pipes. The pipes shall not be damaged, peeled, honeycombed, exposed, cracked, etc. The pipes that fail the appearance inspection shall not be used. 3. The quality of flexible electric ball valve strengthens the protection of pipes. The manufacturer shall be required to strengthen the protection of pipes during transportation and installation.
The flexible electric ball valve produced by the electric ball valve manufacturer Hengchang Pipeline strictly controls the quality of the flexible electric ball valve, controls the quality, constantly requires scientific innovation, wins reputation with quality, makes friends with service, develops new technologies and materials, and has won many honors, Among all electric ball valve manufacturers, flexible electric ball valve manufacturers, electric ball valve manufacturers, and expansion device manufacturers, we ensure quality first, so that our electric ball valve prices, flexible electric ball valve prices, 02s404 flexible electric ball valve prices, electric ball valve prices, double flange limit expansion joint prices, and expansion device prices have the highest cost performance ratio in the market. Purpose of stainless steel electric ball valve Manufacturer Hengchang Pipeline aims at the purpose of stainless steel electric ball valve: stainless steel electric ball valve is applicable to structures (buildings) where the pipeline passes through the wall without bearing pipeline vibration and expansion deformation, and is applicable to the renovation of structures (buildings) or pipelines where the space of the pipeline passes through the wall is limited or the pipeline installation precedes the renovation of structures (buildings) or pipelines. For areas with seismic fortification requirements, if stainless steel electric ball valves are used, flexible connections should be set on the nearby pipes entering the pool wall or building exterior wall. Type A stainless steel electric ball valve is applicable to steel pipe, type B and type C are applicable to ductile iron pipe and cast iron pipe.
Installation together with civil construction "means that when the pipeline passes through the shear wall foundation, beam and special-shaped column of concrete structure, it shall be installed together with civil construction. The reason is that after the hole is reserved, the secondary pouring between the casing and the concrete is not easy to handle; Some cannot be handled, such as installing rigid electric ball valves on the concrete shear wall of basement foundation. For the use of ordinary casing, it is usually made of welded pipes. Both ends of the casing should be cut mechanically (e.g., with a toothless saw), and the wall thickness is not strictly required. Please pay special attention to the above precautions when using and installing, so as to reduce all kinds of unnecessary troubles in your future life or work.
