进口电动切断球阀(V型阀芯，O型阀芯）具有结构紧凑，切换迅速，流通能力大，阀座与端面法兰距离近，物料滞留少，密封性能优良等特点

retz Imported electric cut-off ball valve (V-type valve core, O-type valve core) is characterized by compact structure, rapid switching, large flow capacity, close distance between valve seat and end flange, less material retention, and excellent sealing performance

功能介绍 Function introduction

进口电动切断球阀(V型阀芯，O型阀芯）具有全通径和缩径两种结构形式。用于输送粘性、易结渣介质管道上使用全通径的，方便定期的刮蜡吹扫器通过。进口电动切断球阀2.jpg用于输送气体或物理性能近似于水的介质的管道上宜使用缩径球阀，因其重量比全通径的电动球阀轻30%左右，有利于减轻管道负荷retz The imported electric cut-off ball valve (V-type valve core, O-type valve core) has two structural forms of full bore and reduced bore. It is used for conveying viscous and slag-prone medium, and it is convenient for regular paraffin scraper and purging to pass through. The reduced-diameter ball valve should be used on the pipeline for transporting gas or medium with physical properties similar to water, because its weight is about 30% lighter than the full-diameter electric ball valve, which is beneficial to reducing the pipeline load

设计特色 Design features

采用全通径或缩径设计，流通阻力小 Full bore or reduced bore design, low flow resistance

采用高平台结构，***5211连接标准，能使安装电/气动执行器更为专业化 High platform structure and ***5211 connection standard can make the installation of electric/pneumatic actuators more professional

阀杆采用内装式，轴肩及聚四氟乙烯（或增强石墨）推力垫结构防止阀杆因管道内压力 而吹 出，同时聚四氟乙烯（或增强石墨）材料减小阀门的启闭扭矩，使操作更为省力 The valve rod is internally mounted, with the shoulder and Teflon (or reinforced graphite) thrust pad structure to prevent the valve rod from blowing out due to the pressure in the pipe. At the same time, Teflon (or reinforced graphite) material reduces the opening and closing torque of the valve, making the operation more labor-saving

具有防火防静电结构，在阀杆与阀体及阀杆与球体之间设置导电弹簧，避免因静电打火点燃易燃介质 It has a fireproof and anti-static structure, and a conductive spring is set between the valve rod and the valve body and between the valve rod and the ball to avoid igniting flammable media due to static electricity

耐火结构双重保护，当万一发生火灾而使密封圈烧损时，球阀的各个密封部位均能形成金属对金属的硬密封结构 The fire-resistant structure has double protection. When the sealing ring is burnt in case of fire, all sealing parts of the ball valve can form a metal-to-metal hard sealing structure
