进口不锈钢螺纹球阀
德国托普进口不锈钢螺纹球阀应用领域:
适用于化工、石油、天然气、冶金、等行业及含硫化氢介质、杂质多、腐蚀严重的天然气
进口不锈钢螺纹球阀结构：
1.阀门全开、全关位置的锁紧装置：为防止启、闭阀门的误动作，在全开、全关位置设置有锁定孔。可将阀门位置锁定，以防止其他人误动，以及震动等原因引起的阀位误动，保证设备的安全。
2.阀杆防飞结构：阀杆的下部设计凸肩，装配时将阀杆从阀体内部下装，防止阀内压力生高阀杆飞出。同时也可以在意外火灾后，阀杆与阀体的密封性能。
3.防静电的机能：在使用于可燃性介质如燃点较低的汽油、天燃气、丙烷等易燃介质时，应考虑防止静电的问题，以避免因球体与聚四氟乙烯阀座间的摩擦产生静电而产生爆炸。
4.防火结构：当发生意外火灾时，阀座、填料、垫片等非金属材料被烧毁，为阻止介质的大量泄漏，设计了防火的密封结构。
The locking device 1 the valve is fully open and fully closed position to prevent misoperation of opening and closing the valve, a locking hole is arranged on the fully open and fully closed position. The position of the valve can be locked to prevent other people from moving, as well as the vibration caused by the valve position error, to ensure the safety of equipment.
2 stem anti fly structure: the lower design shoulder of the stem, the assembly will stem from internal under pressure in the valve body, to prevent the high blow out. At the same time, it can also be in the event of fire, the valve stem and valve sealing performance.
3 anti-static function: in use in flammable medium such as low burning gasoline, natural gas, propane and other combustible materials, should be considered to prevent electrostatic problems, to avoid static friction for sphere and PTFE seat between the explosion.
4 fire protection structure: when accidental fire, the valve seat, packing, gasket and other non-metallic materials were burned, in order to prevent a large number of media leakage, the design of the fire sealing structure.
