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?yàn)殚y門(mén)的特殊作用，其具有定期和不定期的檢修維護(hù)需求，因此工業(yè)保溫隔熱中，常常把閥門(mén)位置的保溫工作所忽略。很多工廠有成千上萬(wàn)個(gè)閥門(mén)，如果閥門(mén)不做保溫，具體有什么影響呢？

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?

閥門(mén)保溫原因一：減少隱患

Valve insulation reason 1: reduce hidden dangers

熱力管線(xiàn)上的閥門(mén)，如果不進(jìn)行良好的保溫，在多次開(kāi)啟和關(guān)閉過(guò)程中，由于熱脹冷縮不均勻有可能引起泄漏。從而造成火災(zāi)隱患，或者對(duì)人員造成影響。特別是一些壓力比較大的系統(tǒng)中，如果發(fā)生泄漏，可能造成物料噴濺造成更大影響。

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.

閥門(mén)保溫原因二：影響閥門(mén)的使用壽命

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

在熱交變過(guò)程中，對(duì)同一個(gè)閥門(mén)而言，裸露情況下比有良好保溫的情況下出現(xiàn)熱態(tài)關(guān)閉、冷態(tài)開(kāi)啟的次數(shù)要多。對(duì)于裸露閥門(mén)而言在冷太通流的情況下，如果閥門(mén)零件之間的工作間隙設(shè)計(jì)的不是十分精確的話(huà)，在工作時(shí)發(fā)生擦傷和卡死的可能性要較保溫良好的閥門(mén)發(fā)生的可能性大。如果閥門(mén)內(nèi)外溫差過(guò)大，還容易產(chǎn)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，冬季氣溫迅速下降，閥門(mén)等部位經(jīng)常會(huì)出現(xiàn)凍結(jié)的情況。此時(shí)如果不加以保溫隔熱處理，閥門(mén)就很容易出現(xiàn)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.

閥門(mén)保溫原因三：白白增加能量損耗

Valve insulation reason 3: increase energy loss for nothing

尤其是蒸汽系統(tǒng)中的熱網(wǎng)管線(xiàn)，由于外部環(huán)境與蒸汽的溫差而向環(huán)境散熱，導(dǎo)致蒸汽熱能的白白損耗，閥門(mén)數(shù)量眾多，整體更造成車(chē)間的溫度整體升高，無(wú)形中還會(huì)增加空調(diào)費(fèi)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.

閥門(mén)保溫可以有效減少能量損失，節(jié)約能源，同時(shí)還可以降低企業(yè)運(yùn)行成本，從而提高經(jīng)濟(jì)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.

據(jù)統(tǒng)計(jì)，一只DN100的閥門(mén)在在介質(zhì)溫度為110℃的管線(xiàn)上，未保溫時(shí)的散熱損失為286W，保溫后的散熱損失為26W，減少熱損失260W。以蒸汽單價(jià)250元/噸計(jì)算，每年可節(jié)省費(fèi)用為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.

也并非所有閥門(mén)都需要做保溫

Not all valves need to be insulated

比如有蒸汽系統(tǒng)中一部分的疏水閥，需要降溫閥門(mén)才能打開(kāi)，做保溫以后降溫慢，閥門(mén)開(kāi)啟就會(huì)產(chǎn)生延遲。我們?cè)诰唧w應(yīng)用中，保溫隔熱工作根據(jù)具體工況，可以靈活掌握。

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.

柔性可拆卸閥門(mén)保溫套（衣）的好處

Advantages of flexible removable valve insulation jacket

由此可見(jiàn)，閥門(mén)的保溫工作是一項(xiàng)重要任務(wù)，給閥門(mén)“穿上衣服”，推薦使用科好特柔性可拆卸閥門(mén)保溫套（衣），能有效減少閥門(mén)工作過(guò)程中的熱損失，提高相應(yīng)的經(jīng)濟(jì)效益，改善周?chē)臒岘h(huán)境。還能增加閥門(mén)的使用壽命，防止冬季凍壞。而且，保溫衣的材質(zhì)使用防火、耐酸堿的材料。在一些復(fù)雜工況中也可以使用。

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.

購(gòu)買(mǎi)一個(gè)閥門(mén)保溫套（衣）產(chǎn)品，根據(jù)不同的閥門(mén)大小、保溫厚度、溫度要求、制作工藝等，價(jià)格有所差別，但也不過(guò)幾十幾百元，短期就可以收回投資成本，平時(shí)使用過(guò)程中方便打理和拆卸，為設(shè)備的檢修也提供了很好的保障，可謂一舉多得！

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!
