進(jìn)口低溫截止閥德國(guó)洛克進(jìn)口品牌

進(jìn)口低溫截止閥結(jié)構(gòu)特點(diǎn)：

低溫截止閥以獨(dú)特的加長(zhǎng)型閥桿為基礎(chǔ)點(diǎn)，可讓低溫液態(tài)氣體在加長(zhǎng)閥桿套內(nèi)直接氣化，防止低溫液態(tài)氣體接觸填料零件造成損壞，所有部件采用深冷不銹鋼為主體材料，完全避免使用過程中密封變形泄露,具有開關(guān)靈活、密封可靠的特點(diǎn)

進(jìn)口低溫截止閥設(shè)計(jì)要求：

1、閥門在低溫介質(zhì)及周圍環(huán)境溫度下應(yīng)具有長(zhǎng)時(shí)間工作的能力。

2、閥門不應(yīng)成為低溫系統(tǒng)的一個(gè)顯著熱源。這是因?yàn)闊崃康牧魅氤档蜔嵝释?，如流入過多，還會(huì)使內(nèi)部流體急速蒸發(fā)，產(chǎn)生異常升壓，造成危險(xiǎn)。

3、低溫介質(zhì)不應(yīng)對(duì)手輪操作及填料密封性能產(chǎn)生有害的影響。

4、直接與低溫介質(zhì)接觸的閥門組合件應(yīng)具有防爆和防火結(jié)構(gòu)。

5、在低溫下工作的閥門組合件無法潤(rùn)滑，所以需要采取結(jié)構(gòu)措施，以防止摩擦件擦傷。

Design requirements of imported low temperature stop valve:
1. The valve should be able to work for a long time under low temperature medium and ambient temperature.
2. Valves should not be a significant heat source for cryogenic systems. This is because the inflow of heat not only reduces the thermal efficiency, but also makes the internal fluid evaporate rapidly if the inflow is too much, resulting in abnormal pressure rise and danger.
3. Low temperature medium should not have harmful effect on handwheel operation and packing sealing performance.
4. Valve assemblies in direct contact with low temperature medium shall have explosion-proof and fire-proof structure.
5. Valve assemblies working at low temperature cannot be lubricated, so structural measures should be taken to prevent friction parts from scratching.
                                                                               

進(jìn)口低溫截止閥產(chǎn)品簡(jiǎn)介：

低溫截止閥的閥體采用不銹鋼材質(zhì)，閥體經(jīng)過超低溫的處理，使閥門在極其低溫的條件下，仍然具有極強(qiáng)的耐腐蝕性能，閥門的加長(zhǎng)桿設(shè)置，使得閥門在低溫條件下，不易受影響，閥門還具有結(jié)構(gòu)體積小、重量輕、結(jié)構(gòu)簡(jiǎn)單、密封性好，閥內(nèi)管道對(duì)介質(zhì)阻力較小，閥門安裝拆卸方便，方便于維修，閥門具有雙重密封性能，使用安全可靠，截止閥的密封性極強(qiáng)，所以現(xiàn)在得到的廣泛的使用。

Introduction of imported low temperature stop valve products:
The valve body of the low-temperature stop valve is made of stainless steel. After ultra-low temperature treatment, the valve still has strong corrosion resistance under extremely low temperature conditions. The extension rod of the valve makes the valve not easy to be affected under low temperature conditions. The valve also has the advantages of small volume, light weight, simple structure, good sealing performance, and small resistance of pipeline to medium, The utility model has the advantages of convenient maintenance, convenient installation and strong safety.
