Valve products are widely used, and the performance requirements of valves in different environmental occasions are also different. Here, our Hunan valve manufacturer will introduce a new type - low temperature valve. The working medium of low-temperature valve is mainly flammable and explosive substances, and the low temperature can reach - 269 ℃. Therefore, the following requirements are generally met in the design:

1)支持長(zhǎng)時(shí)間低溫工作

1) Support long-time low-temperature operation

閥門(mén)及其組合件在低溫介質(zhì)及周圍環(huán)境溫度下應(yīng)具有長(zhǎng)時(shí)間工作的能力(一般為10年或是3500~5000次循環(huán));

The valve and its assembly shall be capable of working for a long time under low temperature medium and ambient temperature (generally 10 years or 3500 ~ 5000 cycles);

2)避免成為熱源

2) Avoid becoming a heat source

閥門(mén)相對(duì)于低溫介質(zhì)，不應(yīng)成為一個(gè)顯著熱源，這是因?yàn)闊崃康牧魅霑?huì)降低熱效率，而且熱量流入過(guò)多，還可能使閥門(mén)內(nèi)部的低溫介質(zhì)汽化，產(chǎn)生異常升壓，造成危險(xiǎn);

Compared with the low-temperature medium, the valve should not become a significant heat source, because the inflow of heat will reduce the thermal efficiency, and too much heat inflow may also vaporize the low-temperature medium inside the valve, resulting in abnormal pressure rise and danger;

3)手輪手輪不受低溫影響

3) The handwheel is not affected by low temperature

低溫介質(zhì)不應(yīng)對(duì)手輪的操作性能和填料的密封性能產(chǎn)生有害影響;

Low temperature medium shall not adversely affect the operating performance of handwheel and the sealing performance of packing;

4)防爆防火

4) Explosion proof and fire prevention

直接和低溫介質(zhì)接觸的閥門(mén)組合件的結(jié)構(gòu)應(yīng)當(dāng)符合相關(guān)的防爆和防火要求;

The structure of valve assemblies in direct contact with low-temperature medium shall meet relevant explosion-proof and fire-proof requirements;

5)預(yù)防摩擦部件擦傷

5) Prevent chafing parts

在低溫狀態(tài)下工作的閥門(mén)組合件不能潤(rùn)滑，所以需要采取措施，防止摩擦部件被擦傷。

The valve assembly working at low temperature cannot be lubricated, so measures need to be taken to prevent the friction parts from being scratched.
