BQ41H一體式保溫球閥_球閥_閥門_機械設備_貨源

S48@VUK_Z6$G$)%BR[~[6)E_

該產品具有良好的保溫保冷特性,且閥門的通徑與管徑一致,同時又能有效降低管路中介質熱量損失。主要用於石油、化工、冶金、制藥、食品等各類系統中，以輸送常
溫下會凝固的高粘度介質。
由於采用整體式結構，因而保溫球閥比一般球閥體積更小，重量更輕，且無外漏,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。

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.
