Features
The product bears favorable heat-preservation ａnd cold-insulation specialties.In addition, the all-diameter of the valve is identical to pipe diameter to effectively reduce the heat loss from those medium in the pipeline. It is mainly applied to transport the full- bodied mediums which solidify under normal temperature in such fields as petroleum industry, chemical industry, metallurgical industry, pharmaceutical industry,food industry, etc.
For the monolithic construction is applied in design the product, the jacket valve with favorable sealing performance features smaller configuration ａnd weight than traditional ball valves without leakage. More overpressure-resistant ａnd firmer capacities are also
enjoyed by the jacket made through carbon steel welding than that through casting.

BQ41F縮徑保溫夾套球閥具有保溫、保冷特性。按GB設(shè)計(jì)制造法蘭連接按79-94標(biāo)準(zhǔn)制造用于石油、化工、冶金、制藥行業(yè)。以輸送常溫下會(huì)凝固的高粘度介質(zhì)。雙德BQ41F縮徑保溫夾套球閥由于采用了蒸氣夾套保溫。故即使外界溫度降到零度以下，該閥仍操作靈活保證輸油管道能斷開，其優(yōu)點(diǎn)是一般控制閥門所沒有的。它是重油輸送管道理想的控制閥門。
根據(jù)用戶需要夾套注入蒸氣、導(dǎo)熱油、冷卻水、冷氣等。使用整個(gè)閥門長(zhǎng)溫或降溫達(dá)到所需要的溫度。能防止介質(zhì)結(jié)晶。 BQ41F縮徑保溫球閥產(chǎn)品具有良好的保溫保冷特性，具閥門的痛徑與管徑一致，同時(shí)又能有效降管路中介質(zhì)熱量損失。主要用于石油、化工、冶金、制藥、食品等各類系統(tǒng)中，以輸送還常溫下會(huì)凝固的高粘度介質(zhì)。由于采用整體式結(jié)構(gòu)，因而保溫球閥比一般球閥體積更小，重量更輕，且無(wú)外漏,密封性能良好，夾套采用碳素鋼管焊接比鑄造的更加耐壓牢固。 |
