The precision of product size shall be set before the production of electric ball valve. Before the production of electric ball valve, we first need to blanking, and blanking should have a certain value, rather than blind blanking. Now customers need CAD drawings when purchasing expansion joints, electric ball valves, valve soft joints and other products, so our manufacturers should strictly follow the requirements of the drawings when producing, and there will be errors. We do any products with data, It will not be said that there is not a little error, but the error should not be too large, which will affect the use of electric ball valve and the construction of the project. The main purpose of production and assembly is to connect each individual part into a whole electric ball valve product, so that it has a predetermined size and position accuracy.
The reasonable production and assembly process should meet the requirements of product use. It should not only make the product easy to process, but also make its production and assembly convenient and economical. The production and assembly precision of the product is not only related to the precision of the parts processing electric ball valve product, but also related to the production and assembly process method. The relationship between the three can be analyzed using the dimension chain principle.
After the production and assembly of electric ball valve products, the total error of production and assembly parameters may be greater than, equal to or less than the production and assembly tolerance specified in the drawing. To ensure the production and assembly accuracy of electric ball valve and electric ball valve products, it is necessary to select appropriate production and assembly process methods to make the total error of production and assembly smaller or equal to the specified production and assembly tolerance. According to the specific production conditions and production types, there are five types of process methods to ensure the assembly accuracy of electric ball valve products: complete exchange production assembly method, incomplete exchange production assembly method, selective production assembly method, adjustment production assembly method and repair method. Our company can produce all kinds of electric ball valves and electric ball valves for pipelines with national standards and different standards. No matter from the outer diameter of the pipe to the installation length, there is no error, which can ensure the safe construction of the pipeline. We can also draw drawings for all kinds of electric ball valves for you, and they can be produced after verification.
