進口鍛鋼閘閥

德國鍛鋼閘閥的啟閉件是閘板，閘板的運動方向與流體方向相垂直，閘閥只能作全開和全關 , 本類閥門在管道中一般應當水平安裝。不能作調節和節流。閘板有兩個密封面 , 最常用的模式閘板閥的兩個密封面形成楔形、楔形角隨閥門參數而異 , 通常為 50, 介質溫度不高時為 2°52' 。楔式閘閥的閘板可以做成一個整 體，叫做剛性閘板；也可以做成能產生微量變形的閘板 , 以改善其工藝性 , 彌補密封面角度在加工過程中產生的偏差 , 這種閘板叫做彈性閘板。期以來市場上使用的一般閘閥普遍存在著漏水或生銹現象，利用德國高科技橡膠及閥門制造技術所生產的彈性座封閘閥，克服了一般閘閥密封不良，生銹等缺陷，彈性座封閘閥利用彈性閘板產生微量彈性變形的補償作用達到良好的密封效果，該閥具有開關輕巧、密封可靠、彈性記憶佳及使用壽命等顯著優點。可廣泛用于自來水、污水、建筑、石油、化工、食品、醫藥、輕紡、電力、船舶、冶金、能源系統等體管線上作為調節和截流裝置使用。

進口鍛鋼閘閥關閉時

　　密封面可以只依靠介質壓力來密封 , 即依靠介質壓力將閘板的密封面壓向另一側的閥座來保證密封面的密封，這就是自密封。大部分閘閥是采用強制密封的 , 即閥門關閉時，要依靠外力強行將閘板壓向閥座 , 以保證密封面的密封性。

　　閘閥的閘板隨閥桿一起作直線運動的，叫升降桿閘閥 ( 亦叫明桿閘閥)。通常在升降桿上 有梯形螺紋，通過閥門頂端的螺母以及閥體上的導槽，將旋轉運動變為直線運動 , 也就是將操作轉矩變為操作推力。

進口鍛鋼閘閥開啟閥門時

　　當閘板提升高度等于閥門通徑的1：1倍時，流體的通道完全暢通，但在運行時，此位置是無法監視的。實際使用時，是以閥桿的頂點作為標志，即開不動的位置，作為它的全開位置。為考慮溫度變化出現鎖死現象，通常在開到頂點位置上，再倒回1/2－1圈，作為全開閥門的位置。因此， 閥門的全開位置，按閘板的位置（即行程〉來確定。

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.
