Now various industries are trying to find ways to reduce costs, and some valve industry owners in the cost reduction, it is found that the valve design costs for their overall cost impact is relatively large. Then, how does the design cost of the valve affect the overall cost of the valve?

The influence of design factors on cost is mainly manifested in the following aspects:

1, design the product function rationality

??The functional rationality of the designed product will affect the manufacturing cost and market reputation of the product, and affect the potential market of the product. The most reasonable design is to design a product that meets the user's requirements and minimizes the cost to itself. Therefore, as a valve designer, to collect user information, careful statistics and analysis, and then determine the basic function is complete, and has a certain basic type of valve can be improved as the setting of the series valve products.

?   This type can meet most users' requirements, and higher performance requirements, for those more a few users, we can based on the basic type, simple changes and combination, to meet the requirements. Such a product is a reasonable design, in order to truly reasonable cost to a minimum.

2. the design of product structure is reasonable

Product design will affect the process of structure rationality to the blank and the weight of the product, thereby affecting the purchasing costs of raw materials and process cost. For valve designers, "weight loss enhancement" is a constant pursuit.

For the valve of the special pressure vessel, because of the complexity of the structure and the shape of it, because the actual pressure uncertainty, not fixed, because it works in the pipeline on the actual capacity uncertainty due to the instability of the physical and chemical properties of the main material, due to lack of corrosion data of various materials in different medium and under pressure, so far not a perfect mechanical (strength and stiffness) calculation theory, which can meet the performance of products, but also can make the minimum weight of product.

However, with the progress of science, the development of material science and mechanics, especially the application of computer technology in the field of mechanics of materials, we calculate material ability is gradually improve, how to design a more reasonable structure, more reasonable and more reasonable weight shape products, will be the direction of each a valve designer.

3. design the product process rationality

The rationality of product design process rationality will affect the process, affect the processing cost. Products and parts of the structure of simple and complex processing, surface design, with precision design, assembly design form will affect the model making, blank forming, processing difficulty, processing and processing time, assembly difficulty, painting and packing transportation difficulty etc.. Therefore, a designer's craft experience is of paramount importance in the design process.

As a qualified designer, not only with the design, calculation, but also a process of knowledge, familiar with the whole process of their products. Whether it is the casting model making, casting, annealing and forging blank blanking, stamping molding, welding molding, welding or postprocessing parts, all parts of the machining process, assembly method and test process, and all kinds of standard parts of the size, performance, must have sufficient understanding. Only in this way can the actual design of the process experience be applied so as to avoid the waste of the product design in the process.

4. Design the appearance rationality of the product

The appearance of the product design rationality will affect the product's market volume, thereby affecting the batch cost. Machine design industry popular "experience", then called "ugly, it must be unreasonable."". That is to say, if the shape of the product we design is not good, there must be some unreasonable places in the stiffness and strength. And unreasonable shape, in order to achieve the required intensity, to meet the use of performance, it is necessary to increase the material to achieve. Therefore, a reasonable shape design is not only good-looking appearance, but also can save material and reduce costs.

Therefore, the user chooses the product of a certain enterprise according to the appearance, and must not simply say "look at the outward appearance, not see the essence". It is also based on these considerations, the German valve for the product packaging has also been trying to achieve beautiful appearance, beautiful appearance, packaging intact. Because once this product through the trial, it would be easy to form bulk orders, and if a product can be mass production, its utilization rate, process model, fluency, and management cost by the material will be greatly reduced.

5. Design the quality and rationality of the product

The quality of the product is affected by the quality of the product, especially the cost of after service. The quality of products not only determines the life of a product, but also determin
