天津明杆闸阀厂家告诉你什么是明杆闸阀?
天津明杆闸阀厂家告诉你闸阀的开启和关闭部件为闸板,闸板的运动方向与流体方向垂直。闸阀只能完全打开和关闭,不能调节和节流。闸门有两个密封面。最常见模式闸阀的两个密封面形成楔形,楔形角随阀门参数而变化,通常为50.当介质温度不高时,为2°52'。楔式闸阀的闸门可以做成一个整体,称为刚性闸门;也可以将其制成能够产生轻微变形的冲头,以提高其加工性能,并补偿加工过程中密封表面角度的偏差。这种闸板称为弹性闸板。
天津明杆闸阀厂家告诉你明杆闸阀的类型根据密封面配置可分为楔形闸阀和平行闸阀,楔形闸阀也可分为单闸阀、双闸阀和弹性闸阀;平行闸阀可分为单闸板和双闸板。根据阀杆的螺纹位置,可分为升杆闸阀和非升杆闸阀。当升杆闸阀关闭时,密封面只能由介质压力密封,也就是说,闸板的密封面只能通过介质压力压向另一侧的阀座,以确保密封面的密封,这就是自密封。大多数闸阀采用强制密封,即当阀门关闭时,应通过外力将闸板压到阀座上,以确保密封面的密封性。转动手轮,提升或降低与阀杆连接的阀板,通过手轮和阀杆之间螺纹的进退来打开和关闭阀门
天津明杆闸阀厂家告诉你明杆闸阀具有以下优点:
流体阻力小,密封表面较少被介质冲刷和侵蚀。它更容易打开和关闭。介质的流动方向不受限制,流动不受干扰,压力不降低。形状简单,结构长度短,制造工艺好,应用范围广。
升杆闸阀的缺点如下:密封表面之间容易产生腐蚀和磨损,维护相对困难。整体尺寸大,打开需要一定的空间,打开和关闭时间长。结构复杂。闸阀的类型根据密封面配置可分为楔形闸阀和平行闸阀,楔形闸阀也可分为单闸板极型、双闸板型和弹性闸板型;平行闸阀可分为单闸板和双闸板。根据阀杆的螺纹位置,可分为升杆闸阀和非升杆闸阀。明杆闸阀的特点:
重量轻:阀体由高级球墨铸铁制成,比传统闸阀轻约20%~30%,易于安装和维护。
平底阀座:传统的闸阀通常具有与水管机相同的平底设计,因此不容易导致石头、木块、水泥、废铁、碎屑等异物沉积在阀门底部凹槽中,由于无法紧密关闭,容易造成漏水。整体橡胶涂层:闸板采用优质橡胶进行整体内部和外部橡胶涂层。欧洲的橡胶硫化技术使硫化闸板能够精确的几何尺寸,橡胶和韧性铸造闸板连接牢固,不易脱落,具有良好的弹性记忆。精密铸造阀体:阀体由精密铸造制成,精确的几何尺寸使其能够确保阀门的密封,而无需在阀体内部进行任何修整。
