RETZ瑞茨『进口天然气截止阀』详细介绍●RETZ截止阀系列●RETZ天然气截止阀●产品数据
?进口天然气截止阀描述--
RETZ天然气截止阀采用弹性V型聚匹氮乙烯或丁晴橡胶作为动密封填料, 由填料盖/不锈钢弹簧提供初始密封，填料密封性能随介质压力上升而增强,即具有自密封性能，无需人工维护
RETZ natural gas cut-off valve adopts the elastic V type PPPL or butadiene rubber as the dynamic seal packing, which provides the initial seal by the packing cover / stainless steel spring. The packing seal performance is enhanced with the pressure of the medium, that is, it has self sealing performance without manual maintenance.
?进口天然气截止阀特征--
1.开关轻松，密封性能好
2.阀杆填料自动密封：填料采用(PTFE+丁睛橡胶)复合软成形填料，增加弹簧自动补偿，利用管道压力产生自动密封，密封填料磨损弹簧自动补偿。
3.密封填料损坏可带压更换填料。(手轮逆时针万向转到顶点上密封产生密封，拿下手轮，松开填料室.拿下填料，更换复合软成形填料（PDFE+丁晴橡胶+弹簧)。
4.阀杆耐磨功能：填料室增加PDFE，使阀杆不会和填料室摩擦，增强阀杆使用寿命。
5.开启时将阀杆提到点，令填料与上密封同时起密封作用，关闭时关闭力不要过大，以免破坏密封面。
1. easy switch, good sealing performance
2. valve stem packing automatic seal: packing (PTFE+ butadiene rubber) composite soft forming packing, increasing spring automatic compensation, automatic seal using pipe pressure, sealing packing wear spring automatic compensation.
3. seal filler damage can be replaced with pressure. (hand wheel reverse clockwise to the top seal to seal, take off the handwheel, loose the packing room. Take down the packing, replace the composite soft forming packing (PDFE+ butadiene rubber + spring).
4. stem wear resistance: packing chamber increases PDFE, so that the stem will not be friction with the packing chamber, and enhance the service life of the stem.
5. when the valve is opened, the stem is mentioned to the highest point, so that the packing and the upper seal are sealed at the same time, and the closing force is not too large when closing, so as not to damage the sealing surface.
