1 目前阀门标准方面存在的问题

1.1 阀门检查验收标准不统一

可能会有人解释这样做是为了吸收和采用国外先进标准。但笔者认为:制修订标准时积极采用国际标准和国外先进标准是完全正确和应该的,问题是要经过分析对比,学其所长,取其精华,形成自己的体系,不能见到一个搬一个,使自己的标准五花八门,乱了套路,成为国外标准的混合体。国外工业发达国家的标准经常修订,但总也不会乱了体系。例如美国石油协会的 API598《阀门试验与检验》标准,经过 20 年的多次修改,发展为 API598-96 第七版,但标准号始终还是 API598,只是在年号上和版本上作相应改变。而不象我们修改后另起新号,使人们无法分辨新旧标准的发展轨迹。德国的阀门供货标准 DIN3230,是采用在标准号下又分列分号的办法。如 DIN3230-Pt1 供货技术条件,Pt2 供货一般要求,Pt3 试验总汇,Pt4 供水阀试验,Pt5 煤气阀检验等,这种编号给人以条理清晰的感觉,值得我们借鉴。

1.3 阀门标准与法兰标准不配套

1.4 阀门结构长度不统一

阀门除了连接法兰本身尺寸标准较乱以外,两端法兰面之间的尺寸——结构长度也分长、中、短系列。对同一个压力级同一个规格口径的阀门,过去的阀门结构长度尺寸是唯一的,要更换一台阀门只要选好型号、压力、口径,买来一定能安装到管道法兰间。现在采用新的标准不行了,首先阀门没有一个统一的结构长度标准可查,有一个标准是 GB12221《法兰连接金属阀门结构长度》,列出的是法兰阀门的结构长度,可是又包括了对夹式蝶阀止回阀的结构长度。又有一个标准是 GB/T15188《阀门的结构长度》,从标准名字看,这个标准应该是包括所有阀门,可是它只包括了对焊连接、对夹连接和内外螺纹连接的小口径阀门,而不包括法兰连接阀门,而且对夹连接的蝶阀和止回阀与 GB12221 中的压力口径范围又不相同,让人无所适从。另外承插焊连接,卡套、卡箍连接的阀门其结构长度又无从查找或者根本没有标准。即使好不容易从 ZBJ16005《锻钢阀门》中找到了几个口径的内螺纹连接、承插焊连接的阀门的结构长度尺寸,过了几年又被 JB/T7746 所代替,其内容中的内螺纹、承插焊结构长度尺寸表又变了,还有一些阀门的结构长度分别“埋藏”在不同的专门产品标准中。例如在 GB12233 中能找到内螺纹阀门结构长度,在 GB12240 中也有内螺纹连接阀门的结构长度,在 GB12237 中又能找到对焊连接阀门的结构长度尺寸表,其中有些和 GB/T5188 又不一致。
