主要性能 Main performance

(排污)进口高温导热油，蒸汽球阀是直接依靠介质压力产生的作用力来帮助作用于阀瓣上的机械荷密封的，作用在阀瓣上的机械载荷主要是来自压缩弹簧，这种几乎是固定的机械载荷。虽然对于压缩弹簧，加载的排污阀可以通过调整弹簧力来达到良好密封，但密封压差 必须足够强，以保证足够的密封力，从而在阀正常运行时达到密封。密封压差还应小于启闭压差，以确保开启灵活  RETZ integrated high-temperature blowdown ball valve directly relies on the force generated by the medium pressure to help seal the mechanical load acting on the valve disc. The mechanical load acting on the valve disc mainly comes from the compression spring, which is almost a fixed mechanical load. Although the loaded blowdown valve can achieve good sealing by adjusting the spring force for compression spring, the sealing pressure difference must be strong enough to ensure sufficient sealing force, so as to achieve sealing during normal operation of the valve. The sealing differential pressure should also be less than the opening and closing differential pressure to ensure flexible opening.

(排污)进口高温导热油，蒸汽球阀 特点∶ Performance characteristics

1、先进的阀座：聚多年球阀制造经验而设计的阀座，确保阀门密封，磨擦系数低，操作力矩小、多种阀座材料、适应范围广  Advanced valve seat: the valve seat designed based on years of ball valve manufacturing experience ensures the valve sealing, low friction coefficient, small operating torque, multiple valve seat materials, and wide application range

2、开关无误的手柄：采用扁头阀杆，与手柄的连接不会错位，从而保证手柄指示的开关状态与阀一致辞 RETZ Handle with correct opening and closing: flat head valve stem is used, and the connection with the handle will not be misplaced, so as to ensure the opening and closing status indicated by the handle and the valve address

3、锁紧装置：为防止阀门开关误操作，在阀门全开、全关位置有锁定孔，确保阀门处于正确的位置  Locking device: to prevent misoperation of valve opening and closing, there are locking holes in the fully open and closed positions of the valve to ensure that the valve is in the correct position

4、阀杆防飞结构：阀杆为下装式，防止受压飞出，同时可在火灾后，与阀体形成金属接触，确保阀杆密封  RETZ Anti flying structure of the valve stem: the valve stem is bottom mounted to prevent pressure from flying out, and can form metal contact with the valve body after a fire to ensure the sealing of the valve stem
