进口不锈钢法兰截止阀

 

德国巴赫进口不锈钢法兰截止阀概述：Overview of stainless steel flanged stop valves imported from Germany by Bach:

进口不锈钢法兰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，不锈钢截止阀具有非常可靠的切断动作，使得这种阀门非常适合作为介质的切断或调节及节流使用。Imported stainless steel flange stop valve stem axis and valve seat sealing surface vertical. Valve opening or closing stroke is relatively short, stainless steel stop valve has a very reliable cutting action, so that this valve is very suitable for cutting or regulating medium and throttling use.

进口不锈钢法兰截止阀一旦处于开启状态，它的阀座和阀瓣密封面之间就不再有接触，因而它的密封面机械磨损较小，由于大部分不锈钢截止阀的阀座和阀瓣比较容易修理或更换密封元件时无需把整个阀门从管线上拆下来，这对于阀门和管线焊接成一体的场合是很适用的。介质通过此类阀门时的流动方向发生了变化，因此不锈钢法兰截止阀的流动阻力较高于其它阀门。

Germany Bach imported stainless steel flange valve overview:

Imported stainless steel flange valve stem axis and valve seat sealing surface vertical. Valve stem to open or close the trip is relatively short, stainless steel valve has a very reliable cutting action, making this valve is very suitable for use as a medium cut or regulation and throttle use.

Imported stainless steel flange once the valve is turned on, there is no contact with its seat and disc sealing surface between the sealing surface mechanical wear small, because there is no need to remove the valve from the pipeline most stainless steel valve seat and valve easily repaired or replaced seals, for this the valves and pipes welded into one of the occasion is appropriate. The flow direction of the medium is changed by the valve, so the flow resistance of the stainless steel flange is higher than that of other valves.
进口不锈钢法兰截止阀的定义：Definition of stainless steel flanged stop valve:   

1、不锈钢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、截止阀全开时阀瓣经常受冲蚀。

The definition of imported stainless steel flange valve:

1, stainless steel gate valve structure than simple, easy to manufacture and maintenance.

2, the sealing surface is not easy to wear and abrasion, good sealing, open and close the valve flap and the valve body sealing surface between the relative sliding, so wear and abrasion are not serious, good sealing performance, long service life.

3, open and close, the valve flap stroke is small, so the valve height than the gate valve is small, but the length of the structure than the gate length.

4, opening and closing torque is large, open and close more laborious, open and close time principal.

5, fluid resistance, due to the valve body in the media channel more twists and turns, fluid resistance, power consumption.

6, medium flow direction: nominal pressure PN is less than 16MPa, generally use the media from the valve downstream, under the direction of flow; nominal pressure PN = 20MPa, using reflux, medium from the valve on the downstream direction to increase the seal. When the utility model is used, the valve can only flow in one direction and can not change the flow direction.

7, the valve is fully open when the valve flap is subject to erosion.
