閥門是流體（液體、氣體、氣液混合或固液混合體）輸送系統(tǒng)中的控制部件，具有截止、調(diào)節(jié)、導(dǎo)流、防止逆流、穩(wěn)壓、分流或溢流泄壓等功能，是工業(yè)系統(tǒng)中必不可少的常用設(shè)備之一。
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.
因為閥門的特殊作用，其具有定期和不定期的檢修維護需求，因此工業(yè)保溫隔熱中，常常把閥門位置的保溫工作所忽略。很多工廠有成千上萬個閥門，如果閥門不做保溫，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?
閥門保溫原因一：減少隱患
Valve insulation reason 1: reduce hidden dangers
熱力管線上的閥門，如果不進行良好的保溫，在多次開啟和關(guān)閉過程中，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.
閥門保溫原因二：影響閥門的使用壽命
Valve insulation reason 2: affect the service life of the valve
在熱交變過程中，對同一個閥門而言，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)開啟的次數(shù)要多。對于裸露閥門而言在冷太通流的情況下，如果閥門零件之間的工作間隙設(shè)計的不是十分精確的話，在工作時發(fā)生擦傷和卡死的可能性要較保溫良好的閥門發(fā)生的可能性大。如果閥門內(nèi)外溫差過大，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，閥門等部位經(jīng)常會出現(xiàn)凍結(jié)的情況。此時如果不加以保溫隔熱處理，閥門就很容易出現(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，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，閥門數(shù)量眾多，整體更造成車間的溫度整體升高，無形中還會增加空調(diào)費用。
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.
閥門保溫可以有效減少能量損失，節(jié)約能源，同時還可以降低企業(yè)運行成本，從而提高經(jīng)濟效益。
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，一只DN100的閥門在在介質(zhì)溫度為110℃的管線上，未保溫時的散熱損失為286W，保溫后的散熱損失為26W，減少熱損失260W。以蒸汽單價250元/噸計算，每年可節(jié)省費用為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，需要降溫閥門才能打開，做保溫以后降溫慢，閥門開啟就會產(chǎn)生延遲。我們在具體應(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.
柔性可拆卸閥門保溫套（衣）的好處
Advantages of flexible removable valve insulation jacket
由此可見，閥門的保溫工作是一項重要任務(wù)，給閥門“穿上衣服”，推薦使用科好特柔性可拆卸閥門保溫套（衣），能有效減少閥門工作過程中的熱損失，提高相應(yīng)的經(jīng)濟效益，改善周圍的熱環(huán)境。還能增加閥門的使用壽命，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.
購買一個閥門保溫套（衣）產(chǎn)品，根據(jù)不同的閥門大小、保溫厚度、溫度要求、制作工藝等，價格有所差別，但也不過幾十幾百元，短期就可以收回投資成本，平時使用過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!
