RETZ瑞茨『进口真空截止阀』详细介绍●RETZ真空阀系列●RETZ真空截止阀●产品数据
?进口真空截止阀描述--
RETZ真空截止阀用途广泛，适用于工作温度≤425℃和≤550℃，可用于半真空，中级，真空条件下。作为启闭装置，尤其适用于火电厂汽机冷凝和真空负压系统。
RETZ vacuum cut-off valves are widely used for working temperatures of less than 425 degrees centigrade and less than 550 degrees Celsius. They can be used in semi vacuum, intermediate and advanced vacuum conditions. As an opening and closing device, it is especially suitable for steam turbine condensing and vacuum negative pressure systems in thermal power plants.
?进口真空截止阀设计特点--
1.启闭迅速，扭拒小
2.安装长度短，传导系数
3.密封面运动摩擦力小，启闭轻便，而且密封面磨损有自动补偿功能。
4.阀盖调料室设有真空密封结构，具有自胀压紧作用，并且密封采用高强膨胀材料密封，使系统与大气完全隔离，具有很好的系统气密性。
1. opening and closing quickly and little twisting
2. the shortest installation length and the maximum conduction coefficient
3., the friction surface of the sealing surface is small, the opening and closing is light, and the surface of the seal has automatic compensation function.
The 4. valve cover dressing room has a vacuum sealing structure, with self expansion and pressure tightening, and sealed with high strength expansion material, so that the system is completely isolated from the atmosphere and has a good system air tightness.
