The valve is the control component in the fluid (liquid, gas, gas-liquid mixture or solid-liquid mixture) transmission system. It has the functions of cut-off, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief. It is one of the essential common equipment in the industrial system.

因为阀门的特殊作用，其具有定期和不定期的检修维护需求，因此工业保温隔热中，常常把阀门位置的保温工作所忽略。很多工厂有成千上万个阀门，如果阀门不做保温，具体有什么影响呢？

Because of the special function of the valve, it has regular and irregular maintenance needs. Therefore, in the industrial thermal insulation, the thermal insulation of the valve position is often neglected. Many factories have thousands of valves. If the valves are not insulated, what will be the specific impact?

阀门保温原因一：减少隐患

Valve insulation reason 1: reduce hidden dangers

热力管线上的阀门，如果不进行良好的保温，在多次开启和关闭过程中，由于热胀冷缩不均匀有可能引起泄漏。从而造成火灾隐患，或者对人员造成影响。特别是一些压力比较大的系统中，如果发生泄漏，可能造成物料喷溅造成更大影响。

If the valves on the heating pipeline are not well insulated, leakage may occur due to uneven thermal expansion and contraction during multiple opening and closing. Thereby causing fire hazards or affecting personnel. Especially in some systems with high pressure, if leakage occurs, it may cause material splashing and cause greater impact.

阀门保温原因二：影响阀门的使用寿命

Valve insulation reason 2: affect the service life of the valve

在热交变过程中，对同一个阀门而言，裸露情况下比有良好保温的情况下出现热态关闭、冷态开启的次数要多。对于裸露阀门而言在冷太通流的情况下，如果阀门零件之间的工作间隙设计的不是十分精确的话，在工作时发生擦伤和卡死的可能性要较保温良好的阀门发生的可能性大。如果阀门内外温差过大，还容易产生冷凝水。

In the process of thermal alternation, for the same valve, the number of hot state closing and cold state opening is more when it is exposed than when it is well insulated. For exposed valves, if the working clearance between valve parts is not designed accurately, the possibility of scratch and jamming during operation is greater than that of valves with good thermal insulation. If the temperature difference between the inside and outside of the valve is too large, it is easy to produce condensed water.

另外，冬季气温迅速下降，阀门等部位经常会出现冻结的情况。此时如果不加以保温隔热处理，阀门就很容易出现故障。

In addition, the temperature drops rapidly in winter, and valves and other parts often freeze. At this time, if no thermal insulation treatment is carried out, the valve is easy to fail.

阀门保温原因三：白白增加能量损耗

Valve insulation reason 3: increase energy loss for nothing

尤其是蒸汽系统中的热网管线，由于外部环境与蒸汽的温差而向环境散热，导致蒸汽热能的白白损耗，阀门数量众多，整体更造成车间的温度整体升高，无形中还会增加空调费用。

In particular, the heat supply network pipeline in the steam system radiates heat to the environment due to the temperature difference between the external environment and the steam, resulting in the white loss of steam heat energy, the large number of valves, and the overall increase in the temperature of the workshop, and the invisible increase in air conditioning costs.

阀门保温可以有效减少能量损失，节约能源，同时还可以降低企业运行成本，从而提高经济效益。

Valve insulation can effectively reduce energy loss, save energy, and also reduce the operating cost of enterprises, so as to improve economic efficiency.

据统计，一只DN100的阀门在在介质温度为110℃的管线上，未保温时的散热损失为286W，保温后的散热损失为26W，减少热损失260W。以蒸汽单价250元/吨计算，每年可节省费用为1000元。

According to statistics, a DN100 valve on the pipeline with a medium temperature of 110 ℃ has a heat loss of 286w when it is not insulated, 26W after insulation, and 260W less heat loss. If the unit price of steam is 250 yuan / ton, the annual cost can be saved as 1000 yuan.

也并非所有阀门都需要做保温

Not all valves need to be insulated

比如有蒸汽系统中一部分的疏水阀，需要降温阀门才能打开，做保温以后降温慢，阀门开启就会产生延迟。我们在具体应用中，保温隔热工作根据具体工况，可以灵活掌握。

For example, there is a part of the drain valve in the steam system, which can only be opened when the temperature is lowered. If the temperature is lowered slowly after thermal insulation, the opening of the valve will be delayed. In our specific application, the thermal insulation work can be flexibly mastered according to the specific working conditions.

柔性可拆卸阀门保温套（衣）的好处

Advantages of flexible removable valve insulation jacket

由此可见，阀门的保温工作是一项重要任务，给阀门“穿上衣服”，使用科好特柔性可拆卸阀门保温套（衣），能有效减少阀门工作过程中的热损失，提高相应的经济效益，改善周围的热环境。还能增加阀门的使用寿命，防止冬季冻坏。而且，保温衣的材质使用防火、耐酸碱的材料。在一些复杂工况中也可以使用。

It can be seen that the thermal insulation work of valves is an important task. It is recommended to "put on clothes" for valves. It is recommended to use Kehao special flexible detachable valve thermal insulation jacket (clothes), which can effectively reduce the heat loss during the working process of valves, improve the corresponding economic benefits and improve the surrounding thermal environment. It can also increase the service life of the valve and prevent freezing damage in winter. Moreover, the material of the thermal insulation coat is fireproof and acid and alkali resistant. It can also be used in some complex working conditions.

购买一个阀门保温套（衣）产品，根据不同的阀门大小、保温厚度、温度要求、制作工艺等，有所差别，但也不过几十几百元，短期就可以收回投资成本，平时使用过程中方便打理和拆卸，为设备的检修也提供了很好的保障，可谓一举多得！

The price of a valve insulation jacket (clothing) product varies according to the valve size, insulation thickness, temperature requirements, and manufacturing process, but it is only a few hundred yuan. The investment cost can be recovered in the short term. It is convenient to take care of and disassemble in the normal use process, and provides a good guarantee for the maintenance of the equipment. It can be said that it can do more with one stone!
