| 全焊接球阀性能： Performance of all welded ball valve: 1)：不需要维护，调整及润滑，易于安装，在低运行费用下长期可靠运行。表面采用喷塑处理技术，光泽美观，在国内已处于领先水平。不会有外部泄漏等现象。阀体是焊接结构，所以阀门重量轻且易于进行绝缘。安装调节机构，非常简便，操作手柄可以拆下，换向安装。 1): it does not need maintenance, adjustment and lubrication, is easy to install, and operates reliably for a long time under low operating cost. The surface adopts spray plastic treatment technology, with beautiful luster, which has been in the leading level in China. There will be no external leakage. The valve body is welded, so the valve is light and easy to insulate. It is very simple to install the adjusting mechanism. The operating handle can be removed and installed by reversing. 2)：由于阀座是由碳纤维增强特氟隆密封环及碟形簧构成的，所以对压力和温度的变化适应能力强，在标注压力和温度范围内不会产生任何泄滑。 2): since the valve seat is composed of carbon fiber reinforced Teflon sealing ring and disc spring, it has strong adaptability to the change of pressure and temperature, and will not produce any leakage within the range of pressure and temperature indicated. 3)：球体的加工过程有先进的计算机检测仪跟踪检测，所以球体的加工精度高。 3): the machining process of the sphere is tracked and detected by an advanced computer detector, so the machining accuracy of the sphere is high. 4)：由于阀体材料跟管道材质一样，不会出现应力不均，也不会由于地震及车辆经过地面时而产生变形，管道耐老化。 4): as the valve body material is the same as the pipe material, there will be no uneven stress, and there will be no deformation due to the earthquake and when the vehicle passes the ground, so the pipe is resistant to aging. 5)：整体式全焊接，等径及变径通道，采用固定球及浮动球，双活塞效应密封系统，自动注入密封剂式轴承。 5): integral full welding, equal diameter and variable diameter channels, fixed ball and floating ball, double piston effect sealing system, automatic injection of sealant bearing. 6)：为了防止静电，阀杆与球体以及阀杆与填料箱之间分别装有钢球和弹簧，可以保持阀门所有零件与阀体的导电，让电流通过区，释放静电。不仅防止火灾，而且防止腐蚀，实现临时性切断，以便及时检修。 6): in order to prevent static electricity, steel balls and springs are installed between the valve rod and the ball and between the valve rod and the packing box respectively, which can keep the conductivity of all parts of the valve and the valve body, let the current pass through the area and release static electricity. Not only to prevent fire, but also to prevent corrosion, to achieve temporary cut-off, so that timely maintenance. 7)：阀杆防脱功能是因为阀杆受阀内压力影响，总产生脱离的力所以阀杆设计成防脱结构。 7): the anti stripping function of the valve stem is because the valve stem is affected by the internal pressure of the valve, which always produces the force of disengagement, so the valve stem is designed as an anti stripping structure. 8)：用低摩擦材料的止推垫圈支撑将压力推向阀杆，使阀杆仅仅起到传递扭矩的作用。 8): push the pressure to the valve rod with the low friction material thrust washer support, so that the valve rod only plays the role of transmitting torque. |
