详细参数    

进口锻钢闸阀

德国锻钢闸阀的启闭件是闸板,闸板的运动方向与流体方向相垂直,闸阀只能作全开和全关 , 本类阀门在管道中一般应当水平安装。不能作调节和节流。闸板有两个密封面 , 最常用的模式闸板阀的两个密封面形成楔形、楔形角随阀门参数而异 , 通常为 50, 介质温度不高时为 2°52' 。楔式闸阀的闸板可以做成一个整 体,叫做刚性闸板;也可以做成能产生微量变形的闸板 , 以改善其工艺性 , 弥补密封面角度在加工过程中产生的偏差 , 这种闸板叫做弹性闸板。期以来市场上使用的一般闸阀普遍存在着漏水或生锈现象,利用德国高科技橡胶及阀门制造技术所生产的弹性座封闸阀,克服了一般闸阀密封不良,生锈等缺陷,弹性座封闸阀利用弹性闸板产生微量弹性变形的补偿作用达到良好的密封效果,该阀具有开关轻巧、密封可靠、弹性记忆佳及使用寿命等显著优点。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。

进口锻钢闸阀关闭时

  密封面可以只依靠介质压力来密封 , 即依靠介质压力将闸板的密封面压向另一侧的阀座来保证密封面的密封,这就是自密封。大部分闸阀是采用强制密封的 , 即阀门关闭时,要依靠外力强行将闸板压向阀座 , 以保证密封面的密封性。

  闸阀的闸板随阀杆一起作直线运动的,叫升降杆闸阀 ( 亦叫明杆闸阀)。通常在升降杆上 有梯形螺纹,通过阀门顶端的螺母以及阀体上的导槽,将旋转运动变为直线运动 , 也就是将操作转矩变为操作推力。

进口锻钢闸阀开启阀门时

  当闸板提升高度等于阀门通径的1:1倍时,流体的通道完全畅通,但在运行时,此位置是无法监视的。实际使用时,是以阀杆的顶点作为标志,即开不动的位置,作为它的全开位置。为考虑温度变化出现锁死现象,通常在开到顶点位置上,再倒回1/2-1圈,作为全开阀门的位置。因此, 阀门的全开位置,按闸板的位置(即行程〉来确定。

进口阀门锻钢高温闸阀:标准尺寸:DN15~2000压力等级:1.0-32mpa适用温度:-196~800℃,阀体材料:碳钢,不锈钢,内件材质:碳钢,不锈钢,操作方式:手动,气动,产地:德国,产品品牌:德国Orsen奥尔申 ,其产品和服务在化工、石化、石油、造纸、蒸汽、天然气、采矿、电力、液化气、食品、制药、给排水等领域市场处于领先地位。

Imported forged steel valve

German forged steel gate valve opening and closing parts is, the direction of movement of the fluid direction perpendicular to the gate, gate can only be fully open and fully closed, this type valve generally be installed horizontally in the pipeline. Can not be adjusted and the throttle. Ram has two sealing surface, the two most common mode of sealing surface to form a wedge gate valve, wedge angle with the valve parameters vary, usually 50, the medium temperature is not high for 2 ° 52 '. Wedge gate valve can be made into a whole, called the rigid gate; can also be made to produce small quantities of deformation gate in order to improve its process, to make up the sealing surface angle deviations arising during processing, this gate board called the flexible gate. Since the term is generally used on the market gate leakage or rusting widespread use of German high-tech rubber valve manufacturing technology and the production of resilient seated gate valve, to overcome the general bad valve seals, rust and other defects, resilient seated gate valve use flexible gate trace produce elastic deformation compensation to achieve a good seal, the valve has a switch, lightweight, reliable sealing, excellent elastic memory and life and other significant advantages. Can be widely used as a regulator and shutoff device using the water, sewage, construction, petroleum, chemical, food, pharmaceutical, textile, electric power, shipbuilding, metallurgy, energy systems and other body pipelines.

Imported forged steel valve is closed

Sealing surface can only rely on media pressure to seal, which rely on the sealing surface of the medium pressure to ram pressure to the other side of the seat to ensure the sealing surface, which is self-sealing. Most of the valve is sealed by force, that is, when the valve is closed, to rely on external pressure to force the gate valve to ensure the tightness of the sealing surface.

Gate valve with the valve stem linear movement, called the lift rod valve (also called clear shot valve). Often movements are trapezoidal threaded rod through the top of the valve guides and valve nut on the rotary motion into linear motion, which is the operating torque thrust into action.

Imported forged steel valve when the valve is opened

When the gate valve lift height equal to the diameter of the 1: 1 times, the fluid channel is completely smooth, but at run time, this position is not monitored. Actual use, is the apex of the stem as a sign that the fixed position, as its fully open position. Temperature appears to consider locking phenomenon, usually open to the vertex position, and then rewind 1 / 2-1 circle, as the position of the valve fully open. Therefore, the fully open position of the valve, according to gate position (ie, travel> to determine.

Hot forged steel valve inlet valve: Standard size: DN15 ~ 2000 pressure levels: 1.0-32mpa Temperature: -196 ~ 800 ℃, body material: carbon steel, stainless steel, inner parts material: carbon steel, stainless steel, operating modes: manual Pneumatic, Origin: Germany Brand: Germany Orsen Orr Shen, its products and services in the chemical, petrochemical, oil, paper, steam, gas, mining, electricity, gas, food, pharmaceutical, water supply and drainage areas of the market in leader.
