閥門生產廠家機械加工常用的毛坯有鑄件、鍛件、型材及焊接件。不同的毛坯種類以及毛坯的精度、粗糙度和硬度等對機械加工工藝過程有著直接的影響。

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.

選擇閥門毛坯時應考慮如下的一些素：

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

零件的材料及對材料的組織和性能要求。設計圖上規定的零件材料，大體上就決定了毛坯的種類。例如，零件材料為鑄鐵就必須用鑄造方法來制造毛坯。對于鋼制零 件，在選擇毛坯時應考慮對材料的力學性能要求。例如，制造高壓閥門的零件一般應晝選用鍛件或焊接件，以保證材料具有良好的力學性能。 濕度傳感器探頭,不銹鋼電熱管 PT100 傳感器,鑄鋁加熱器,加熱圈,流體電磁閥

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.

零件的結構形狀和外形尺寸。零件的結構開關是影響毛坯選擇的重要因素，例如，結構開關復雜的閥體可選用鑄件。尺寸大的閥體可選用砂型鑄造;尺寸小的則采用熔模鑄造。

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.

生產綱領的大小。零件的生產綱領愈大，采用高精度和率的毛坯制造方法經濟效果愈好。

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.

毛坯制造的條件。應根據現場的設備善和工藝水平來選擇毛坯，并考慮到發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.
