The production standards for high-pressure shut-off valves in power plants usually refer to international standards, national standards, and industry standards. The following are some common production standards for high-pressure shut-off valves in power plants:

1. 標(biāo)準(zhǔn)：常見(jiàn)的標(biāo)準(zhǔn)包括標(biāo)準(zhǔn)化組織（ISO）和電工委員會(huì)（IEC）發(fā)布的標(biāo)準(zhǔn)。例如，ISO 15761-1《工業(yè)閥門(mén)-截止閥-部分：構(gòu)造和尺寸》和IEC 60534-4-2《流體控制設(shè)備-閥門(mén)-第4-2部分：工業(yè)過(guò)程閥-閥 D表示法 的閥門(mén)型式》等。

1. International standards: Common international standards include those issued by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). For example, ISO 15761-1 "Industrial valves - Globe valves - Part 1: Construction and dimensions" and IEC 60534-4-2 "Fluid control equipment - Valves - Part 4-2: Valve types for industrial process valves - Valve D representation".

2. 國(guó)家標(biāo)準(zhǔn)：國(guó)家標(biāo)準(zhǔn)由國(guó)家標(biāo)準(zhǔn)化管理委員會(huì)（SAC）發(fā)布。適用于電站高壓截止閥的國(guó)家標(biāo)準(zhǔn)包括GB/T、GB、GB/T等系列標(biāo)準(zhǔn)。例如，GB/T 12237-2015《工業(yè)閥門(mén)通則》和GB/T 12238-2008《工業(yè)閥門(mén)術(shù)語(yǔ)》等。

2. National Standards: In China, national standards are issued by the National Standardization Administration Committee (SAC). The national standards applicable to high-pressure shut-off valves in power plants include series of standards such as GB/T, GB, and GB/T. For example, GB/T 12237-2015 "General Principles for Industrial Valves" and GB/T 12238-2008 "Terminology of Industrial Valves".

3. 行業(yè)標(biāo)準(zhǔn)：除了標(biāo)準(zhǔn)和國(guó)家標(biāo)準(zhǔn)，根據(jù)不同行業(yè)的需求，還可以參考相應(yīng)行業(yè)協(xié)會(huì)或組織發(fā)布的標(biāo)準(zhǔn)。例如，在發(fā)電行業(yè)，可以參考電力行業(yè)標(biāo)準(zhǔn)，如DL/T、DL、DL/T、DL/T等系列標(biāo)準(zhǔn)。例如，DL/T 1081-2013《火力發(fā)電廠安裝工程建設(shè)與設(shè)計(jì)上基本標(biāo)準(zhǔn)》和DL/T 592-2014《電力企業(yè)施工與質(zhì)量檢驗(yàn)規(guī)范 法蘭閥門(mén)構(gòu)筑物》等。

3. Industry standards: In addition to international and national standards, according to the needs of different industries, standards published by corresponding industry associations or organizations can also be referenced. For example, in the power generation industry, reference can be made to the power industry standards, such as DL/T, DL/T, DL/T, and other series of standards. For example, DL/T 1081-2013 "Basic Standards for Construction and Design of Thermal Power Plant Installation Engineering" and DL/T 592-2014 "Code for Construction and Quality Inspection of Electric Power Enterprises - Flange Valve Structures".

需要注意的是，生產(chǎn)廠家在生產(chǎn)電站高壓截止閥時(shí)，通常會(huì)參考以上標(biāo)準(zhǔn)，并嚴(yán)格按照標(biāo)準(zhǔn)要求進(jìn)行設(shè)計(jì)、制造和檢驗(yàn)，以確保產(chǎn)品的質(zhì)量和性能符合要求，并滿足電站系統(tǒng)的安全可靠運(yùn)行。

It should be noted that manufacturers usually refer to the above standards when producing high-pressure stop valves for power plants, and strictly follow the standard requirements for design, manufacturing, and inspection to ensure that the quality and performance of the products meet the requirements and meet the safe and reliable operation of the power plant system.
