    实验室气路系统主要由气源切换系统、管道系统、调压系统、用气点、监控及报警系统组成。对于一些易燃易爆气体,如氢气、乙炔等,可能在设计和施工过程中稍有差异,必须加入气体回火防止器等安全控制装置。那么实验室气路系统设计的标准有哪些?
    The laboratory gas circuit system is mainly composed of gas source switching system, pipeline system, pressure regulating system, gas consumption point, monitoring and alarm system. For some flammable and explosive gases, such as hydrogen and acetylene, there may be slight differences in the design and construction process, and gas flashback preventers and other safety control devices must be added. So what are the standards for the design of laboratory gas circuit system?
    在气体管路中的设计,需要做到以下几点:
    In the design of gas pipeline, the following points shall be achieved:
    1、管道设计根据仪器端的压力值,用量来确定管径的大小。
    1. The pipe diameter shall be determined according to the pressure value and consumption at the instrument end.
    2、所有气体管路都由高质量的、完全退火型、无缝连接的不锈钢管组成。
    2. All gas pipelines are composed of high-quality, fully annealed and seamless stainless steel pipes.
    3、所有的管路、阀门、压力表都由高质量的全不锈钢构成,并且都是标准配件。
    3. All pipelines, valves and pressure gauges are made of high-quality all stainless steel and are standard accessories.
    4、仪器的气体管路靠在仪器台后面。
    4. The gas pipeline of the instrument rests against the back of the instrument table.
    5、易燃气体,如乙炔与氢气,需要和其他气体分开,单独引人。

    5. Flammable gases, such as acetylene and hydrogen, need to be separated from other gases and introduced separately.
    实验室规划设计是实验室建设中必不可少的一部分,它的重要性是不言而喻的。
    Laboratory planning and design is an essential part of laboratory construction, and its importance is self-evident.
    一、防火
    1、 Fire prevention
    实验室当中会有各种各样的产生霍的设备,比如说酒精灯、电炉等等。这些都是有一定的安全隐患的,所以,我们在使用这些东西的时候,我们需要注意燃烧的三个基本要素:着火源、可燃物、助燃物,避免在火源附近出现助燃物引起火灾。
    There will be all kinds of equipment in the laboratory, such as alcohol lamp, electric stove and so on. These have certain potential safety hazards. Therefore, when we use these things, we need to pay attention to the three basic elements of combustion: ignition source, combustibles and combustion aids, so as to avoid fire caused by combustion aids near the fire source.
    二、防毒
    2、 Antivirus
    差不多所有的实验室都是会使用到有毒试剂的,所以我们在使用这些有毒物质的时候,一定要弄清楚毒物的理化特性、使用的方法以及应急措施。实验室规划的实验室设候要将药品和试剂通内容相符合的标签,如果是剧毒物品还需要做好“五双”制度。
    Almost all laboratories will use toxic reagents, so when we use these toxic substances, we must find out the physical and chemical characteristics, use methods and emergency measures of the poisons. During the laboratory design of laboratory planning, drugs and reagents shall be labeled according to the content. In case of highly toxic substances, the "five pairs" system shall also be done well.
    三、防水
    3、 Waterproof
    每一个实验室都会有纯水、高纯水或者是制作水的设备,比如说蒸馏器。而操作人员很可能在操作的过程当中忘记了要关闭水龙头,或者是土壤停水之后忘记关闭的。因此,在进行实验室规划的时候务必要做好防水措施。
    Every laboratory will have pure water, high-purity water or water making equipment, such as a distiller. The operator may forget to turn off the tap during the operation, or forget to turn off after the soil water is cut off. Therefore, it is necessary to take waterproof measures when planning the laboratory.
    四、防触电
    4、 Anti electric shock
    从用电的设备说起,电源的插座一定要接地线,如果是大功率的仪器、电气设备还需要接空气开关,实验室规划要做好漏电保护。此外,在使用电气设备的时候不能用带水的手去接触开关,在对设备进行检修的时候要做到停机、断电、挂牌这三个步骤。
    Starting from the electrical equipment, the power socket must be grounded. If it is a high-power instrument and electrical equipment, it also needs to be connected to the air switch. The laboratory planning should do a good job in leakage protection. In addition, when using electrical equipment, do not touch the switch with a hand with water. When overhauling the equipment, do the three steps of shutdown, power off and listing.
