进口锻钢焊接闸阀德国巴赫进口锻钢焊接闸阀概述：?进口锻钢焊接闸阀有三种阀盖设计形式。*种是螺栓式连接阀盖，按这种设计形式设计的闸阀，其阀体与阀盖用螺栓接连，缠绕式垫片（304夹柔性石墨制造）或采用金属环连接密封。第二种设计形式是焊接式阀盖，按这种设计形式的闸阀，其阀体育阀盖用螺栓连接，全焊密封。第三种是压力自密封式阀盖，按这种设计形式设计的闸阀，其阀体与阀盖用螺栓连接，内压自密封环密封。Forged steel gate valveGermany Bach imported forged steel gate valve overview:Forged steel welding gate valve cover design in three forms. The first is bolted to the valve cover, according to the design of the design of the gate valve, the valve body and valve cover with a bolt, winding gasket (304 folder flexible graphite manufacturing) or the use of metal ring seal. The second form of design is the welded valve cover, according to the design of the gate valve, the valve cover of the valve cover with bolts, all welded seal. The third is the pressure self sealing valve cover, according to the design of the gate valve, the valve body and valve cover with bolts, internal pressure seal ring seal.进口锻钢焊接闸阀的定义：???看来锻钢焊接闸阀适用于Class150～2500、工作温度-29～425℃（碳钢）或 -29～500℃（不锈钢）的小口径管路上，用于截断或接通管路中的介质，选用不同的材质，可分别适用于水、蒸汽、油品、硝酸、醋酸、氧化性介质、尿素等多种介质。在石油管道上应用较多。The definition of forged steel welding gate:It is suitable for gate valve Class150 to 2500, the working temperature of -29 to 425 DEG C welding forged steel (Tan Gang) or -29 to 500 DEG C (stainless steel) small caliber pipeline, used to cut off or connect the line of medium, use different materials, can be separay applied to water, steam, oil, nitric acid, acetic acid, oxidation medium, urea and other media.
