进口不锈钢球阀,(德国奥莱斯OLES阀门品牌)
【进口不锈钢球阀】详细说明:
弹性球体是在球体内壁的下端开一条弹性槽,而获得弹性。当关闭通道
时,用阀杆的楔形头使球体涨开与阀座压紧达到密封。在转动球体之前
先松开楔形头,球体随之恢复原原形,使球体与阀座之间出现很小的间
隙,可以减少密封面的摩擦和操作扭矩。三通球阀有T型和L型。T型能
使三条正交的管道相互联通和切断第三条通道,起分流、合流作用。L
型只能连接相互正交的两条管道,不能同时保持第三条管道的相互连通
,只起分配作用。
Elastic sphere is an elastic groove opened at the lower end of the sphere wall to obtain elasticity. When the channel is closed
The wedge head of the stem is used to make the sphere open and the valve seat compressed to seal. Before turning the sphere
The wedge head is loosened first, and the sphere is restored to its original shape, resulting in a very small gap between the sphere and the valve seat.
The clearance can reduce the friction and operating torque of the sealing surface. Three-way ball valves have T-type and L-type. T-type energy
The three orthogonal pipelines are connected with each other and the third passage is cut off to act as diversion and confluence. L
Type I can only connect two orthogonal pipes, but can not maintain the connection of the third pipe at the same time.
It only plays a distributive role.
【进口不锈钢球阀】结构说明:
流体阻力小、球阀是所有阀类中流体阻力小的一种,即使是缩径球阀,其流体阻力也相当小。止推轴承减小阀杆磨擦力矩,可使阀杆*操作平稳灵活。阀座密封性能好,采用聚四氟乙烯等弹性材料制成的密封圈,结构易于密封,而且球阀的阀封能力随着介质压力的增高而增大。阀杆密封可靠,由于阀杆只作彷转动运而不做升降运动,阀杆的填料密封不易破坏,且密封能力随着介质的压力增高而增大。由于聚四氟乙烯等材料具有良好的自润滑性,与球阀的磨擦损失小,故球阀的使用寿命长。。下装式阀杆和阀杆头部凸阶防止阀杆喷出,如火灾造成阀杆密封破坏,凸阶与阀体间还可形成金属接触,确保阀杆密封。防静电功能:在球体、阀杆、阀体之间设置弹簧,能将开关过程产生的静电导出。
【进口不锈钢球阀】特性:
双块和排气阀门保证双隔离函数由于两个闭孔插入一个单独的身体和他们提供流血函数通过一个流血/通风系统位于闭孔(身体港口和球,门或针阀),从浮动球阀设计、医疗数据备份系统阀门和几个不同的结构。
双固定球铰接在支架上,浮动金属或软阀座,中心针排气阀
