Specification of ball valve model:
With the acceleration of the development of industrial machinery manufacturing industry, the application of valve products with social and industrial progress from low pressure, normal temperature development to high pressure, high temperature, and the use of ball valves is also increasing year by year. For different medium requirements and different working conditions, the ball valve models used are not the same, the multi-instrument valve model editing method provided here, mainly from the increase of additional conditions of the ball valve, the choice of driving mode, the connection of different forms, the change of structural form, the type of sealing material, the level of valve pressure and the valve body material more convenient to explain, For users in the ball valve selection and the correct recognition of the ball valve procurement.
Ball valve model preparation method:
