阀门生产厂家机械加工常用的毛坯有铸件、锻件、型材及焊接件。不同的毛坯种类以及毛坯的精度、粗糙度和硬度等对机械加工工艺过程有着直接的影响。

The commonly used blanks for mechanical processing by valve manufacturers include castings, forgings, profiles, and welded parts. The different types of blanks and the precision, roughness, and hardness of the blanks have a direct impact on the machining process.

选择阀门毛坯时应考虑如下的一些素：

When selecting valve blanks, the following factors should be considered:

零件的材料及对材料的组织和性能要求。设计图上规定的零件材料，大体上就决定了毛坯的种类。例如，零件材料为铸铁就必须用铸造方法来制造毛坯。对于钢制零 件，在选择毛坯时应考虑对材料的力学性能要求。例如，制造高压阀门的零件一般应昼选用锻件或焊接件，以保证材料具有良好的力学性能。 湿度传感器探头,不锈钢电热管 PT100 传感器,铸铝加热器,加热圈,流体电磁阀

The material of the parts and the requirements for the organization and properties of the materials. The material specified on the design drawing generally determines the type of blank. For example, if the component material is cast iron, the casting method must be used to manufacture the blank. For steel parts, the mechanical performance requirements of the material should be considered when selecting the blank. For example, parts for manufacturing high-pressure valves should generally be forged or welded to ensure that the material has good mechanical properties.

零件的结构形状和外形尺寸。零件的结构开关是影响毛坯选择的重要因素，例如，结构开关复杂的阀体可选用铸件。尺寸大的阀体可选用砂型铸造;尺寸小的则采用熔模铸造。

The structural shape and external dimensions of the parts. The structural switch of the component is an important factor affecting the selection of the blank. For example, for valve bodies with complex structural switches, castings can be selected. Large valve bodies can be cast in sand molds; For smaller sizes, investment casting is used.

生产纲领的大小。零件的生产纲领愈大，采用高精度和率的毛坯制造方法经济效果愈好。

The size of the production program. The larger the production program of the parts, the better the economic effect of using high-precision and high-efficiency blank manufacturing methods.

毛坯制造的条件。应根据现场的设备善和工艺水平来选择毛坯，并考虑到发展前景而逐步采用的毛坯制造方法。

The conditions for rough manufacturing. The selection of raw materials should be based on the on-site equipment and technological level, and advanced raw material manufacturing methods should be gradually adopted considering development prospects.
