进口燃气截止阀 液化气 天然气专用截至阀

进口燃气截止阀性能描述 Performance description

燃气截止阀（液化气，天然气专用截至阀）采用V型成型四氟为动密封、以填料压着为初始密封、随着介质压力上升而填料密封性能增强、既具有自密封功能The gas shut-off valve (liquefied gas, natural gas specialized shut-off valve) adopts V-shaped shaped PTFE as the dynamic seal, with the initial seal of packing pressure, and the sealing performance of the packing increases with the increase of medium pressure. It has both self sealing function

进口燃气截止阀产品详情 Product details

天然气专用截至阀增加了一个上密封.在阀门开启状态时,与填料一起两层密封作用,并对填料有一定的保护作用 ，并可带压更换复合软成形填料 RETZ An upper seal is added to the special stop valve for liquefied gas and fuel gas When the valve is open, it has a two-layer sealing effect with the packing, and has a certain protective effect on the packing, and can replace the composite soft forming packing under pressure

采用 PTFE制品作密封面,填料为复合软成形填料（PTFE+丁晴橡胶+弹簧）,上密封也为软材质,密封性能较好 PTFE products are used as the sealing surface. The filler is a composite soft shaped filler (PTFE+NBR+spring). The upper seal is also made of soft material, with good sealing performance

进口燃气截止阀主要特点DESIGN FEATURES

1.开关轻松，密封性能好 Easy switching and good sealing performance

2.阀杆填料自动密封：填料采用（PTFE+丁晴橡胶）复合软成形填料，下增加弹簧自动补偿，利用管道压力产生自动密封， 密封填料磨损弹簧自动补偿 retz品牌 Automatic sealing of valve stem packing: (PTFE+Buna-N rubber) composite soft shaped packing is used as the packing, and the lower spring is added for automatic compensation. The pipe pressure is used to generate automatic sealing, and the worn spring of the sealing packing is automatically compensated

3.密封填料损坏—带压更换填料。（手轮逆时针方向转到顶点，上密封产生密封，拿下手轮，松开填料室，拿下填料室，更换复合软成形填料（PTFE+丁晴橡胶+弹簧）The sealing packing is damaged - replace the packing under pressure. (Turn the hand wheel counterclockwise to the top, and the upper seal will produce a seal. Take off the hand wheel, loosen the packing chamber, take down the packing chamber, and replace the composite soft shaped packing (PTFE+NBR+spring)

4.阀杆耐磨功能：填料室增加 PTFE，使阀杆不会和填料室摩擦，增强阀杆使用寿命 Wear resistance function of valve rod: PTFE is added to the packing chamber to prevent the valve rod from rubbing with the packing chamber and enhance the service life of the valve rod

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 When opening, lift the valve rod to the highest point, so that the packing and upper seal play a sealing role at the same time The closing force shall not be too large to avoid damaging the sealing surface

6.密封材料特点说明：耐温（-196~120℃），耐腐∶耐强酸强碱、水和各种有机溶剂。无毒害/不粘附/高润滑/耐气候机械性质较软，有“塑料王”之称 Characteristics of sealing materials: temperature resistance (- 196~120 ℃), corrosion resistance: resistance to strong acids and alkalis, water and various organic solvents. No poison/no adhesion/high lubrication/weather resistance Mechanical property is soft, so it is called "the king of plastics"
