The expression of the technical forms and heat treatment process of the pump valve casting
The material of the pump valve casting is high quality and fine grey cast iron. The precise proportion of the product has higher tensile and bending strength when using. The international popular heat treatment process makes the stress deformation of the casting reduce to the minimum, and the long-term use of the casting tends to be more stable.
The pump valve casting has better noise absorbability and vibration absorbability. The casting stability of the valve body also can not be replaced by the cast steel lathe bed and welding lathe bed. The content of the casting process design of the pump valve is usually expressed in the technology files.
The process drawing of the pump valve casting is the most basic and important process file, which is the fundamental basis for the design and preparation of other process files. In the case of single piece and small batch production, the valve body casting process drawing is the process file which can directly guide the production. The casting drawing can be drawn according to the casting process drawing, which reflects the actual shape and size of the casting. It can be used as the basis for casting inspection of valve body, and it is usually used in a large number of production.
The mold assembly drawing of the pump valve casting can be drawn according to the casting process drawing. It can reflect the cavity position, sand core distribution and the main assembly dimensions through mould plane after mould assembling, which can be used to guide the operation of core setting and mould assembling. It is commonly used in the important castings or large quantities production of castings with many sand cores and difficulties.
The process card of the pump valve casting is mainly in the form of the sheet, and briefly describes the main content involved in the casting production process. In the case of single piece and small batch production, the valve body casting process drawing and process card should constitute the whole content of the casting process file. At the same time, the valve body casting process card or workshop issued plan should establish the basis of the casting.
