现代化工业对调节阀有哪些要求大家知道吗

发布时间:2020-06-18 10:51:39   发布人:http://www.sdjingtuo.com
  先进的现代工业是以生产自动化为标志的。从自动化系统的发展历史和进步来看,技术工具的变化起着极其重要的作用。
  Advanced modern industry is marked by production automation. From the development history and progress of automation system, the change of technical tools plays an extremely important role.
  传统使用的调节阀基本满足了许多工业系统的需要,但随着现代工业的大规模发展。如何生产出更多更好的先进产品,如何提高产品质量标准,如何更有效、更安全的运行,如何充分利用资源,节约能源,保护生态环境,人们对调节阀提出了更高的要求。这些需要可归纳如下:
  The traditional control valve basically meets the needs of many industrial systems, but with the large-scale development of modern industry. How to produce more and better advanced products, how to improve product quality standards, how to operate more effectively and safely, how to make full use of resources, how to save energy, and how to protect the ecological environment, people put forward higher requirements for the control valve. These needs can be summarized as follows:
  一,质量更稳定,工作更可靠,操作更安全
气液增压泵
  1、 More stable quality, more reliable operation and safer operation
  在过程控制中,调节器与流体直接接触,一旦发生故障,后果不堪设想。
  In the process control, the regulator is in direct contact with the fluid. Once it breaks down, the consequences are unimaginable.
  为了保证调节阀的工作性能和可靠性,必须满足以下要求:
  In order to ensure the working performance and reliability of the control valve, the following requirements must be met:
  1. 保证调节阀的质量
  1. Ensure the quality of control valve
  控制阀的选择要经过严格的计算;型号、口径和性能应符合要求;控制阀各部件的材料要严格选用,要有足够的强度和刚度,按照国家标准通过压力试验、气密性等试验。
  The selection of control valve shall go through strict calculation; the model, caliber and performance shall meet the requirements; the materials of each part of control valve shall be selected strictly, with sufficient strength and rigidity, and shall pass pressure test, air tightness test and other tests in accordance with national standards.
  2. 确保运行可靠
  2. Ensure reliable operation
  根据我国新颁布的气动调节阀标准(GB/T4213-92),气动执行机构铭牌上应至少注明生产厂家名称、产品型号、额定流量系数、设计编号、产品编号和生产日期。
  According to the newly issued standard of pneumatic control valve (GB / t4213-92), the nameplate of pneumatic actuator shall at least indicate the manufacturer's name, product model, rated flow coefficient, design number, product number and production date.
  表示介质流向的箭头和DN值,以及PN的文字和值,应在阀体上铸造或冲出。重要的阀门应该有适当的附件,如定位器、限制开关等。有足够的安装和操作空间。
  The arrow and DN values indicating the flow direction of the medium, as well as the characters and values of PN, shall be cast or punched out on the valve body. Important valves should have proper accessories, such as positioner, limit switch, etc. There is enough space for installation and operation.
  3.应急设备
  3. Emergency equipment
  高压气体设备发生故障时,为防止直接损坏其他设备,必须在与设备相连的管道上安装截止装置,必要时应安装快速截止阀。
  In case of failure of high-pressure gas equipment, in order to prevent direct damage to other equipment, a stop device must be installed on the pipeline connected with the equipment, and a quick stop valve shall be installed if necessary.
  第二,保护环境
  Second, protect the environment
  保护自然和生活环境的重要性和必要性是众所周知的。调节阀对环境的污染主要是空气污染和噪声。
  The importance and necessity of protecting nature and living environment are well known. Air pollution and noise are the main environmental pollution caused by regulating valve.
  1、为了防止空气污染,阀门的密封部分不能泄漏。
  1. In order to prevent air pollution, the sealing part of the valve shall not leak.
  2. 防止噪音
  2. Noise prevention
  第三,节约能源
  Third, energy conservation
  在使用调节过程中,要对节能阀的结构进行调节、使用、安装、维护。
  In the process of using and adjusting, the structure of energy-saving valve should be adjusted, used, installed and maintained.
  1. 使用低阻抗阀
  1. Use low impedance valve
  2、提高阀芯、阀座密封性能
  2. Improve the sealing performance of valve core and valve seat
  3.尽量使用电动执行机构
  3. Try to use electric actuator
  适用于新能源
  Applicable to new energy
  长期以来,石油是主要能源,近年来,许多新能源(液化天然气、液化煤浆、原子能),从加工到生产、运输、储存,对调节阀提出了更多的特殊要求。
  For a long time, oil is the main energy. In recent years, many new energy sources (liquefied natural gas, liquefied coal slurry, atomic energy), from processing to production, transportation, storage, put forward more special requirements for the control valve.
  与常规调节阀相比,调节阀的设计、制造、试验、检验和使用更加特殊、更加严格,为了确保安全,必须从各个方面加以保证。
  Compared with the conventional control valve, the design, manufacture, test, inspection and use of the control valve are more special and strict. In order to ensure safety, it must be ensured from all aspects.
  未来还会出现更多的问题,为了解决这些问题,有必要对旧的过程控制系统进行改进,或者创造一种新的过程控制方法,而新的系统对调节器也会有更高的要求。
  There will be more problems in the future. In order to solve these problems, it is necessary to improve the old process control system or create a new process control method, and the new system will have higher requirements for regulators.
