安全阀与泄放阀的概述、定义与区别 一、概述 阀门网,阀门论坛,电动调节阀|气动调节阀|自力式调节阀|特殊疑难调节阀,计算选型,流量计算,控制阀阀门,控制阀,设计,资料,阀门标准, 阀门信 安全阀是锅炉、压力容器和其他受压力设备上重要的安全附件。其动作可靠性和性能好坏直接关系到设备和人身的安全，并与节能和环境保护紧密相关。而有的用户和设计部门在选型时，总是选错型号。为此本文对安全阀的选用加以分析。 二、定义 所谓安全阀广义上讲包括泄放阀，从管理规则上看，直接安装在蒸汽锅炉或一类压力容器上，其必要条件是必须得到技术监督部门认可的阀门，狭义上称之为安全阀，其他一般称之为泄放阀。安全阀与泄放阀在结构和性能上很相似，二者都是在超过开启压力时自动排放内部的介质，以保证生产装置的安全。由干存在这种本质上类似性，人们在使用时，往往将二者混同，另外，有些生产装置在规则上也规定选用哪种均可。因此，二者的不同之处往往被忽视。从而也就出现了许多间题。如果要将二者作出比较明确的定义，则可按照《ASME锅炉及压力容器规范》{dy}篇中所阐述的定义来理解： （1）安全阀（Safety Valve） 一种由阀前介质静压力驱动的自动泄压装置。其特征为具有突开的全开启动作。用于气体或蒸汽的场合。 （2）泄放阀（Relief Valve） 又称溢流阀一种由阀前介质静压力驱动的自动泄压装置。它随压力超过开启力的增长而按比例开启。主要用于流体的场合。 （3）安全泄放阀（Safety Relief Valve） 又称安全溢流阀一种由介质压力驱动的自动泄压装置。根据使用场合不同既适用作安全阀也适用作泄放阀。以日本为例，给安全阀和泄放阀作出明确定义的比较少，一般用作锅炉这类大型贮能压力容器的安全装置称之为安全阀，安装在管道上或其他设设施上的称之为泄放阀。不过，若按日本通产省的《火力发电技术》的规定看，设备上安全保障的重要部分，指定使用安全阀，如锅炉、过热器、再热器等。而在减压阀的下侧需要与锅炉和涡轮机相接的场合，都需要安装泄放阀或安全阀。如此看，安全阀要求比泄放阀更具可靠性。另外，从日本劳动省的高压气体管理规则、运输省及各级船舶协会的规则中，对安全排放量的认定和规定来看，我们把保证了排放量的称之为安全阀，而不保证排放量的阀门称作泄放阀。在国内不论全启式或微启式统称为安全阀。

Safety valve and discharge valve for an overview of definition and distinction between First, an overview of network valves, valve forums, Electric control valve | Pneumatic control valve | Self-regulating valve | control valve special difficult to calculate selection, volume, control valves valves, control valves, design, materials, valves standards, the letter Valve Safety valve is a boiler, pressure vessels and other pressure equipment subject to the security of an important attachment. Reliability and performance of its actions have a direct bearing on the safety of equipment and personal, and with energy-saving and environmental protection are closely related. However, some users and the design department at the selection, it always chose the wrong model. In this paper, the choice of safety valve for this analysis. Second, the definition of Broad sense, including the so-called safety valve discharge valve, from a management point of view the rules, directly installed in the steam boiler or pressure vessel on a class of its necessary conditions for technical supervision departments must be approved valves, called the safety valve on the narrowly Other commonly known as discharge valve. Safety valve and the discharge valve in the structure and performance is very similar, both are more than open automatically when the pressure within the discharge medium, in order to ensure the safety of production equipment. From the dry nature of the existence of such a similar nature, people use, often confuse the two, In addition, some production facilities are also provided in the rules which can be chosen. Therefore, the difference between the two are often neglected. So also there were many question. If you want to make a more precise definition of the two may in accordance with "ASME Boiler and Pressure Vessel Code," first enunciated in the definition to understand: (1) safety valve (Safety Valve) A kind of static pressure from the valve before the media-driven automatic pressure relief device. It is characterized by a sudden opening of the full-open action. For gas or steam occasions. (2) Relief Valves (Relief Valve) Also known as the relief valve of a static pressure from the valve before the media-driven automatic pressure relief device. It is with the pressure over opening force to open in proportion to the growth. Is mainly used for fluid occasions. (3) Safety Relief Valve (Safety Relief Valve)? Also known as the safety relief valve of a pressure-driven by the medium of automatic pressure relief device. According to the use of different occasions, both valid for the safety valve is also valid for the discharge valve. Japan, for example, to the safety valve and the bleed valve less clearly defined, the general large-scale energy storage such as a boiler pressure vessel safety device called the safety valve, installed in the pipeline or other established facilities in the said of the discharge valve. However, if according to MITI's "thermal technology" looks at the provisions on the device an important part of security, specify the use of safety valves, such as the boiler, superheater, reheater, and so on. Of the lower side in the valve needs and connecting the boilers and turbines of the occasion, they need to install the bleed valve or safety valve. This perspective, safety valves required more reliable than the bleed valve. In addition, from the Japanese Ministry of Labor of the high-pressure gas management rules, the Ministry of Transport and all levels of the ship association rules, the identification of safety and emissions regulations, we take the guarantee of the emissions called safety valve, but not guaranteed emissions, called the discharge valve valve. Kai-type in the country, whether full time or Enlight-type collectively known as the safety valve.
