進口不銹鋼法蘭截止閥
德國巴赫進口不銹鋼法蘭截止閥概述：
進口不銹鋼法蘭截止閥的閥桿軸線與閥座密封面垂直。閥桿開啟或關(guān)閉行程相對較短，不銹鋼截止閥具有非?？煽康那袛鄤幼?，使得這種閥門非常適合作為介質(zhì)的切斷或調(diào)節(jié)及節(jié)流使用。
進口不銹鋼法蘭截止閥一旦處于開啟狀態(tài)，它的閥座和閥瓣密封面之間就不再有接觸，因而它的密封面機械磨損較小，由于大部分不銹鋼截止閥的閥座和閥瓣比較容易修理或更換密封元件時無需把整個閥門從管線上拆下來，這對于閥門和管線焊接成一體的場合是很適用的。介質(zhì)通過此類閥門時的流動方向發(fā)生了變化，因此不銹鋼法蘭截止閥的流動阻力較高于其它閥門。
Stainless steel flanged globe valve
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.
進口不銹鋼法蘭截止閥的定義：
1、不銹鋼截止閥結(jié)構(gòu)比閘閥簡單，制造與維修都較方便。
2、密封面不易磨損及擦傷，密封性好，啟閉時閥瓣與閥體密封面之間無相對滑動，因而磨損與擦傷均不嚴(yán)重，密封性能好，使用壽命長。
3、啟閉時，閥瓣行程小，因而截止閥高度比閘閥小，但結(jié)構(gòu)長度比閘閥長。
4、啟閉力矩大、啟閉較費力，啟閉時間校長。
5、流體阻力大，因閥體內(nèi)介質(zhì)通道較曲折，流體阻力大，動力消耗大。
6、介質(zhì)流動方向：公稱壓力PN≤16MPa時，一般采用順流，介質(zhì)從閥瓣下方向上流；公稱壓力PN≥20MPa時，一般采用逆流，介質(zhì)從閥瓣上方向下流．以增加密封件能。使用時，截止閥介質(zhì)只能單方向流動，不能改變流動方向。
7、截止閥全開時閥瓣經(jīng)常受沖蝕。
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.
