(浮动式,固定式)进口气动法兰球阀的阀座多选用聚四氟乙烯、对位聚苯等高分子聚合材料,密封性能好,但材料相对较软。由于进口气动法兰球阀2.jpg材料较软,但又要达到一定的密封比压,势必增加启闭扭矩,为了尽量改善此种情况,RETZ采用双斜面弹性密封圈或V形槽弹性密封圈结构设计,利用管道内压力推动球体,帮助密封。当介质压力较小时,密封圈与球体接触面积较小,故有较大的密封比压,确保可靠密封。介质压力较大时,密封圈与球体接触面积增大。故密封圈能承受较大的介质推力而不会损坏。对于工作压力很低的球阀,考虑到介质压力不能确保阀座可靠密封,而预紧力长期使用后又会衰减,故对于低压、超低压或真空工况用球阀,采用弹簧加载的阀座密封结构,能确保球阀长期可靠的密封 retz品牌 (Floating type, fixed type) The valve seat of pneumatic flange ball valve is mostly made of polymer materials such as polytetrafluoroethylene, counterpoint polystyrene, which has good sealing performance, but the material is relatively soft. Since the material is relatively soft, but also needs to reach a certain sealing specific pressure, it is bound to increase the opening and closing torque. In order to try to improve this situation, RETZ adopts the structural design of double bevel elastic seal ring or V-groove elastic seal ring, and uses the pressure in the pipeline to push the ball to help seal. When the medium pressure is small, the contact area between the seal ring and the ball is small, so there is a large sealing specific pressure to ensure reliable sealing. When the medium pressure is large, the contact area between the seal ring and the ball increases. Therefore, the seal ring can withstand large medium thrust without damage. For the ball valve with very low working pressure, considering that the medium pressure cannot ensure the reliable sealing of the valve seat, and the preload will decay after long-term use, the spring loaded valve seat sealing structure is adopted for the ball valve with low pressure, ultra-low pressure or vacuum conditions to ensure the long-term reliable sealing of the ball valve

特点Characteristic

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

2、采用高平台结构,ISO5211连接标准,能使安装电/气动执行器更为专业化 High platform structure and ISO5211 进口进口气动法兰球阀3.jpgconnection standard are adopted to make the installation of electric/pneumatic actuators more professional

3、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 of built-in type. The shaft shoulder and PTFE (or reinforced graphite) thrust pad structure prevent the valve rod from blowing out due to the pressure in the pipeline. At the same time, the PTFE (or reinforced graphite) material reduces the opening and closing torque of the valve, so that the operation is more labor-saving

4、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。确保系统安全 It has a fireproof and anti-static structure. A conductive spring is set between the valve rod and the valve body and between the valve rod and the ball to avoid ignition of flammable media due to static electricity. Ensure system security

5、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. In case of burning of the sealing ring in case of fire, each sealing part of the ball valve can form a metal to metal hard sealing structure
