進口電動切斷球閥(V型閥芯，O型閥芯）具有結(jié)構(gòu)緊湊，切換迅速，流通能力大，閥座與端面法蘭距離近，物料滯留少，密封性能優(yōu)良等特點

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

功能介紹 Function introduction

進口電動切斷球閥(V型閥芯，O型閥芯）具有全通徑和縮徑兩種結(jié)構(gòu)形式。用于輸送粘性、易結(jié)渣介質(zhì)管道上使用全通徑的，方便定期的刮蠟吹掃器通過。進口電動切斷球閥2.jpg用于輸送氣體或物理性能近似于水的介質(zhì)的管道上宜使用縮徑球閥，因其重量比全通徑的電動球閥輕30%左右，有利于減輕管道負荷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

設(shè)計特色 Design features

采用全通徑或縮徑設(shè)計，流通阻力小 Full bore or reduced bore design, low flow resistance

采用高平臺結(jié)構(gòu)，ISO5211連接標(biāo)準(zhǔn)，能使安裝電/氣動執(zhí)行器更為專業(yè)化 High platform structure and ISO5211 connection standard can make the installation of electric/pneumatic actuators more professional

閥桿采用內(nèi)裝式，軸肩及聚四氟乙烯（或增強石墨）推力墊結(jié)構(gòu)防止閥桿因管道內(nèi)壓力 而吹 出，同時聚四氟乙烯（或增強石墨）材料減小閥門的啟閉扭矩，使操作更為省力 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

具有防火防靜電結(jié)構(gòu)，在閥桿與閥體及閥桿與球體之間設(shè)置導(dǎo)電彈簧，避免因靜電打火點燃易燃介質(zhì) 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

耐火結(jié)構(gòu)雙重保護，當(dāng)萬一發(fā)生火災(zāi)而使密封圈燒損時，球閥的各個密封部位均能形成金屬對金屬的硬密封結(jié)構(gòu) 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
