简 介
　　sf6气体单向阀主要用于sf6气体专用压力（密度）表与设备之间的过渡装配。可以使设备在充压下能够更换仪表或进行鉴定及其保养维护。
　　本产品的特点是使用方便，气密性能可靠也可用于其它类似的场所，但必须是非腐蚀性介质相配套的压力表系统。
使用单向阀时，将连接接头上的六方螺母悬紧，阀芯将被打开sf6 气体将通过单向阀进入仪表，进行压力轻度控制，使用完毕悬松六方螺母气路将被切断。备注：本公司也可根据情况满足客户的特殊需要！
introduction
sf6 gas check valves are used as an interim fitting between sf6 gas special pressure (density) gauge and the equipment.it enables replacement or verification or maintenance of the instrument while the equipment is filled with the gas. this instrument features easy utility, reliable sealability, and can be used in similar application where corrosive media does not exist. when using, fasten the hex nut to open the valve, sf6 gas enters the instrument via the valve, pressure is controlled slightly. after using, loosen the hex nut to cut off the gas. note: we can also built to customer’s need.
