進口旋塞閥原理
進口旋塞閥詳細(xì)介紹:
美國歐可旋塞閥是關(guān)閉件或柱塞形的旋轉(zhuǎn)閥,通過旋轉(zhuǎn)90度使閥塞上的通道口與閥體上的通道口相同或分開,實現(xiàn)開啟或關(guān)閉的一種閥門。旋塞閥的閥塞的形狀可成圓柱形或圓錐形。在圓柱形閥塞中,通道一般成矩形;而在錐形閥塞中,通道成梯形。這些形狀使旋塞閥的結(jié)構(gòu)變得輕巧,但同時也產(chǎn)生了一定的損失。旋塞閥最適于作為切斷和接通介質(zhì)以及分流適用,但是依據(jù)適用的性質(zhì)和密封面的耐沖蝕性,有時也可用于節(jié)流。進口旋塞閥密封面之間運動帶有擦拭作用,而在全開時可完全防止與流動介質(zhì)的接觸,故它通常也能用于帶懸浮顆粒的介質(zhì)。旋塞閥的另一個重要特性是它易于適應(yīng)多通道結(jié)構(gòu),以致一個閥可以獲得兩個、三個,甚至四個不同的流道。這樣可以簡化管道系統(tǒng)的設(shè)計、減少閥門用量以及設(shè)備中需要的一些連接配件。
 
 
進口旋塞閥工作原理:
美國歐可旋塞閥的塞體多為圓錐體(也有圓柱體),與閥體的圓錐孔面配合組成密封副。旋塞閥是使用最早的一種閥門,結(jié)構(gòu)簡單、開關(guān)迅速、流體阻力小。普通旋塞閥靠精加工的金屬塞體與閥體間的直接接觸來密封,所以密封性較差,啟閉力大,容易磨損,通常只能用于低(不高于1兆帕)和小口徑(小于100毫米)的場合。
 
 
 
進口旋塞閥主要用途:
美國歐可旋塞閥廣泛地應(yīng)用于油田開采、輸送和精練設(shè)備中,同時也廣泛用于石油化工、化工、煤氣、天然氣、液化石油氣、暖通行業(yè)以及一般工業(yè)中。
 
 

Import plug valves are introduced in detail:

The United States of America Ou plug valve is closed or plunger type rotary valve, rotated through 90 degrees to make the valve plug the mouth of the channel and the channel port on the valve body the same or separate, realize the opening or closing a valve. Plug valve plug into a cylindrical or conical shape. In the cylindrical valve plug, generally rectangular channel; and the conical valve plug, the trapezoidal channel. These shapes allow the plug valve structure becomes lighter, but also produced a certain loss. Plug valve for cutting off and on as medium and the shunt applied, but in accordance with the applicable properties and erosion resistance of the sealing surface, sometimes also can be used for throttling. Plug valve sealing surface with a wiping action between movement, and when in full flow and can completely prevent the medium contact, so it usually can also be used with suspended particles in the medium. Plug valve is another important characteristic is that it is easy to adapt to multi channel structure, so that a valve can be obtained in two, three, or even four different channel. This can simplify the design of piping systems, reducing valve and the amount of equipment required for some connection fittings.

Plug valve working principle:

The United States of America Ou plug valve plug body is a cone (or cylindrical ), and valve conical bore surface matched to form a sealing pair. Plug valve is a valve using the first, has the advantages of simple structure, rapid opening and closing, small fluid resistance. General plug valve plug by the metal finishing and valve body to direct contact between the seal, so poor sealing, opening and closing force, easy abrasion, usually only for low ( less than 1MPa ) and small diameter ( less than 100 mm).

Import plug valves main use:

The United States of America Ou plug valves widely used in oil field exploitation, transportation and refining equipment, but also widely used in petrochemical, chemical, gas, natural gas, liquefied petroleum gas, HVAC industry and general industry.
