进口法兰闸阀(德国OLES奥莱斯阀门)
【进口法兰闸阀】详细说明:
闸阀是一种常见的启闭阀,利用闸板(即启闭件,在闸板中启闭件称为闸板或闸门,闸座称为闸板座)来接通(全开)或截断(全关)管路中的介质。它不允许作为截流用,使用中应避免将闸板微量开启,因高速流动的介质的冲蚀会加速密封面的损坏。闸板在垂直于闸门座通道中心线的片面作为升降运动,象闸门一样截断管路中的介质,故称做闸阀。可广泛用于自来水、污水、建筑、石油、化工、食品、医药、轻纺、电力、船舶、冶金、能源系统等体管线上作为调节和截流装置使用
Gate valve is one of the most common open and close valves. The medium in the pipeline can be connected (fully opened) or cut off (fully closed) by using gate (that is, opening and closing parts, which are called gate or gate in the gate, and gate seat). It is not allowed to be used as interception. It should be avoided to open the gate slightly in use, because the erosion of high-speed flowing media will accelerate the damage of the sealing surface. The gate is called a gate valve because it acts as lifting motion on one side perpendicular to the center line of the gate pedestal passage and cuts off the medium in the pipeline like a gate. It can be widely used in water, sewage, construction, petroleum, chemical industry, food, medicine, textile, power, ship, metallurgy, energy system and other body pipelines as regulating and closing devices.
【进口法兰闸阀】特性:
1、流动阻力小。阀体内部介质通道是直通的,介质成直线流动,流动阻力小。
2、启闭时较省力。是与截止阀相比而言,因为无论是开或闭,闸板运动方向均与介质流动方 向相垂直。
3、高度大,启闭时间长。闸板的启闭行程较大,降是通过螺杆进行的。
4、水锤现象不易产生。原因是关闭时间长。
5、介质可向两侧任意方向流动,易于安装。闸阀通道两侧是对称的。
6、结构长度(系壳体两连接端面之间的距离)较小。
7、形体简单 , 结构长度短,制造工艺性好,适用范围广。
8、结构紧凑,阀门刚性好,通道流畅,流阻数小,密封面采用不锈钢和硬质合金,使用寿命长,采用PTFE填料.密封可靠.操作轻便灵活。
