BQ41F保溫球閥產物特色:

法蘭保溫球閥具備杰出的保溫保冷特征,且閥門的通徑與管徑分歧,同時又能有用下降管 路中介質熱量喪失。首要用于火油、化工、冶金、制藥、食物等各種體系中，以保送常溫下會凝結的高粘度介質。
因(yin)為接(jie)(jie)納全體(ti)式(shi)布(bu)局，因(yin)此保溫球閥(fa)比(bi)普通球閥(fa)體(ti)積更(geng)小，分量更(geng)輕，且(qie)無外漏,密(mi)封機能杰出，夾套(tao)接(jie)(jie)納碳素鋼管(guan)焊接(jie)(jie)比(bi)鍛(duan)造(zao)的加(jia)倍(bei)耐壓安穩。

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.
