进口蒸汽截止阀

蒸汽截止阀（stop valve,Globe Valve）的启闭件是塞形的阀瓣，密封上面呈平面或海锥面，阀瓣沿阀座的中心线作直线运动。阀杆的运动形式，（通用名称：暗杆），也有升降旋转杆式可用于控制空气、水、蒸汽、各种腐蚀性介质、泥浆、油品、液态金属和放射性介质等各种类型流体的流动。因此，这种类型的截流截止阀阀门非常适合作为切断或调节以及节流用。由于该类阀门的阀杆开启或关闭行程相对较短，而且具有非常可靠的切断功能，又由于阀座通口的变化与阀瓣的行程成正比例关系，非常适合于对流量的调节。此阀是德国先进机械技术，采用双层波纹管设计，焊于阀杆保持稳定的运行性能，避免由于阀塞振动引起阀杆振动。在高温情况下，阀杆不与介质接触，确保阀杆零泄漏。同时保证足够的强度和韧性，可以开关上万次。手轮采用人体工程学设计，使用寿命更长，操作轻松便捷。蒸汽截止阀的启闭件是塞形的阀瓣，密封面呈平面或锥面，阀瓣沿流体的中心线作直线运动，也叫截门，是使用最广泛的一种阀门，它之所以广受欢迎，是由于开闭过程中密封面之间摩擦力小，比较耐用，开启高度不大，制造容易，维修方便，不仅适用于中低压，而且适用于高压。广泛适用于食品、医药、石油、化工、天然气、钢铁、环保、造纸等输送管路中做介质切断或流通。

进口蒸汽截止阀 - 优点

(1)蒸汽截止阀结构比闸阀简单，制造与维修都较方便。

(2)密封面不易磨损及擦伤，密封性好，启闭时阀瓣与阀体密封面之间无相对滑动，因而磨损与擦伤均不严重，密封性能好，使用寿命长。

(3)启闭时，阀瓣行程小，因而截止阀高度比闸阀小，但结构长度比闸阀长。

(4)启闭力矩大、启闭较费力，启闭时间校长。

(5)流体阻力大，因阀体内介质通道较曲折，流体阻力大，动力消耗大。

(6)介质流动方向公称压力PN≤16MPa时，一般采用顺流，介质从阀瓣下方向上流；公称压力PN≥20MPa时，一般采用逆流，介质从阀瓣上方向下流．以增加密封件能。使用时，截止阀介质只能单方向流动，不能改变流动方向。

(7)全开时阀瓣经常受冲蚀。蒸汽截止阀的阀杆轴线与阀座密封面垂直。阀杆开启或关闭行程相对较短，并具有非常可靠的切断动作，使得这种阀门适合作为介质的切断或调节及节流使用。

Imported steam stop valve

Steam stop valve (stop valve, Globe Valve) opening and closing parts are plug-shaped valve, seal or sea centerline plane was above the cone, the valve seat along a straight line. Stem form of exercise, (generic name: dark bar), but also lift rotating rod can be used to control air, water, steam, corrosive media, mud, oil, liquid metals and radioactive fluids and other types of media flow. Therefore, this type of shut-off valve shut-off valve is very suitable as cut or regulation and throttle use. As such the valve stem to open or close the relatively short trip, but also has a very reliable cutting function, but also due to travel proportional to changes in the valve seat and the valve port valve is very suitable for flow regulation. This valve is Germany advanced mechanical technology, using double bellows design, welded to the valve stem to maintain a stable operating performance, avoid the vibration caused by the valve plug stem vibration. At high temperatures, the stem is not in contact with the media to ensure zero leakage valve stem. While ensuring sufficient strength and toughness, can be thousands of times the switch. Ergonomically designed hand wheel, longer life, easy and convenient operation. Steam stop valve opening and closing parts of the plug-shaped valve, leaving it flat or cone seal, fluid along the centerline of the valve in a straight line, also known as the cross-sectional doors, is the most widely used as a valve that reason popularity is due to the process of opening and closing between the sealing surface friction is small, more durable, opening height is not easy to manufacture, easy maintenance, not only for low pressure, and is suitable for high pressure. Widely used in food, medicine, petroleum, chemical, natural gas, steel, environmental protection, paper and other media to do the transfer line cut or circulation.

Imported steam stop valve - Benefits

(1) steam stop valve structure simpler than the gate, manufacturing and maintenance are more convenient.

(2) sealing surface easy to wear and abrasion, sealing, and no relative sliding between the valve and valve sealing surface when opening and closing, and thus wear and scratches are not serious, good sealing performance and long service life.

(3) When opening and closing, the valve stroke is small, and therefore smaller than the height of the valve shut-off valves, but the structure is longer than the length of the gate.

(4) opening and closing torque, relatively effortless opening and closing, opening and closing time of the principal.

(5) fluid resistance, due to the valve body media path more tortuous, large fluid resistance, power consumption.

(6) Nominal medium flow direction PN≤16MPa, generally used downstream, upstream from the media under the direction of the valve; when nominal PN≥20MPa, generally countercurrent, media orientation downstream from the valve. To increase the seal performance. When used, the cut-off valve medium can only flow in one direction, you can not change the direction of flow.

(7) when fully open valve is often affected by erosion. Stem and seat sealing surface perpendicular to the axis of the steam shut-off valve. Stem to open or close the relatively short trip, and have very reliable cutting action, making this valve is suitable for medium cut or regulation and throttle use.
