阀门型号编制方法、阀门编号说明 阀门型号通常应表示阀门类型、驱动方式、连接形式、结构特点、公称压力、密封面材料、阀体材料等要素。阀门型号的标准化对阀门的设计、选用、经销，提供了方便。当今阀门的类型和材料种类越来越多，阀门型号的编制也愈来愈复杂。我国虽然有阀门型号编制的统一标准，但逐渐不能适应阀门工业发展的需要。目前，阀门制造厂一般采用统一的编号方法；不能采用统一编号方法的，各生产厂可按自己的情况制订出编号方法。 一单元 二单元 三单元 四单元 五单元 － 六单元 七单元 阀门类型 传动方式 连接型式 结构形式 密封副材料 － 公称压力 阀体材料 □□□□□-□□ 一单元：阀门类型代号类型 安全阀 蝶阀 隔膜阀 止回阀 底阀 截止阀 节流阀 排污阀 球阀 疏水阀 柱塞阀 旋塞阀 减压阀 闸阀 代号 A D G H J L P Q S U X Y Z 二单元：传动方式传动 方式 电磁动 电磁-液动 电-液动 蜗轮 正齿轮 伞齿轮 气动 液动 气-液动 电动 手柄手轮 代号 0 1 2 3 4 5 6 7 8 9 无代号 三单元：连接型式连接方式 内螺纹 外螺纹 两不同连接 法兰 焊接 对夹 卡箍 卡套 代号 1 2 3 4 6 7 8 9 四单元：结构型式 每种阀门的结构型式都不同，请点击下面相应的阀门结构型式编制方法 闸阀结构形式 代号 明杆 楔式 弹性闸板 0 刚性单闸板 1 双闸板 2 平行式 单闸板 3 双闸板 4 暗杆 楔式 单闸板 5 双闸板 6 平行式 单闸板 7 双闸板 8 安全阀结构形式 代号 弹簧 封闭 带散热片 全启式 0 微启式 1 全启式 2 带扳手 全启式 4 不封闭 双弹簧微启式 3 微启式 7 全启式 8 带控制机构 全启式 6 脉冲式 9 杠杆式 5 减压阀结构形式 代号 直接作用波纹管式 1 直接作用薄膜式 2 先导活塞式 3 先导波纹管式 4 先导薄膜式 5 五单元： 密封副材料材料 锡基轴承合金 (巴氏合金) 搪 渗氮钢 18-8系 不锈钢 氟塑料 玻璃 Cr13 不锈钢 衬胶 蒙乃尔合金 尼龙塑料 渗硼钢 衬铅 Mo2Ti 不锈钢 塑料 铜合金 橡胶 硬质合金 阀体直接加工 代号 B C D E F G H J M N P Q R S T X Y W 当密封副的密封面材料不同时，以硬度低的材料代号表示。 六单元：公称压力数值用阿拉伯数字直接表示，它是MPa的10倍 七单元：阀体材料阀体材料 钛及钛合金 碳钢 Cr13系不锈钢 铬钼钢 可锻铸铁 铝合金 18-8系不锈钢 球墨铸铁 Mo2Ti系不锈钢 塑料 铜及铜合金 铬钼钒钢 灰铸铁 代号 A C H I K L P Q R S T V Z 灰铸铁底压阀和钢制中压省略此项 举例：Z543H-16C 伞齿轮传动法兰连接平板闸阀，公称压力1.6MPa，阀体材料为碳钢 阀门的命名 阀门的名称按传动方式、连接形式、结构形式、衬里材料和类型命名。但下面内容在命名中均予省略： (1) 连接形式中：“法兰”。 (2) 结构形式中： a：闸阀的“明杆”、“弹性”、“刚性”和“单闸板”； b：截止阀和节流阀的“直通式”； c：球阀的“浮动”和“直通式”； d：蝶阀的“垂直板式”； e：隔膜阀的“屋脊式”； f：旋塞阀的“填料”和“直通式”； g：止回阀的“直通式”和“单瓣式”； h：安全阀的“不封闭”。 (3) 阀座密封面材料中的材料名称。

Of model for valves, valve No. Description Valve type valve should normally be that type, drive type, connection type, structural features, PN, sealing surface material, body material and other factors. Standardization of the valve type of valve design, use, distribution, provides a convenient. The current type of valve types and materials are more and more models of the preparation of the valve even more complex. Although the preparation of our valve type of uniform standards, but gradually the need for industrial development can not meet the valve. At present, the valve manufacturer usually adopt a unified numbering; not uniform numbering, and the production plants can be worked out his own method of numbering the situation. 1 unit 2 units 3 units 4 units 5 units - 6 units 7 units Valve type of drive structure connected type sealing materials - nominal pressure valve materials □ □ □ □ □ - □ □ 1 unit: type safety valve butterfly valve type codes bottom valve diaphragm valve drain valve throttle valve ball valve Plug valve valve plunger trap Code A D G H J L P Q S U X Y Z 2 units: Transmission Transmission Means of electromagnetic action solenoid - hydraulic power - hydraulic worm gears bevel gear pneumatic fluid angry - hydraulic hand wheel electric handle Code 0123456789 No code Three modules: internal thread connection type connection to connect external thread flange welded on two different folders clamp ring Code 12346789 Four modules: structural type The structureof each valve type are different, please click on the appropriate type of valve structure methodology Gate structural form Ming elastic rod wedge gate 0 Rigid single-gate 1 2 double plate Parallel single-gate 3 4 double plate Dark pole wedge single slide 5 6 double plate Parallel single-gate 7 8 double plate Valve structure code Spring closed with heat sink the entire Kai 0 Weiqi 1 All Kai Type 2 With wrench the entire Kai 4 Not closed double spring Weiqi 3 Weiqi 7 The entire Kai 8 Control agencies with the entire Kai 6 Pulse 9 Leveraged 5 Valve structure code Bellows a direct role Direct role in membrane 2 Pilot Piston 3 Pilot bellows 4 Leading thin film 5 5 units: Sealing Materials Materials tin-based bearing alloys (Babbitt) Boring 18-8 Department of nitrided steel Fluorine plastic glass Cr13 stainless steel Monel alloy stainless steel with rubber nylon plastic lined lead Mo2Ti boride Stainless steel plastic copper alloy carbide valve direct processing of rubber Code B C D E F G H J M N P Q R S T X Y W When the seal pair of sealing surface material is not the same time, low hardness material code, said.

However, in the name of the content herein are the following omitted: (1) connection form: "flange." (2) structural form: a: Valve's "clear shot", "flexible" and "rigid" and "single-gate"; b: cut-off valve andthrottle the "straight through"; c: Valve's "floating" and "straight through"; d: Butterfly "vertical plate"; e: diaphragm "roof-type"; f: Plug the "filler" and "straight through"; g: Valve's "straight through" and "ill with style"; h: safety valve "not closed."
